The relationship between CYP19A1 gene expression in luteinized granulosa cells and follicular estradiol output in women with endometriosis. J Steroid Biochem Mol Biol 2024; 237:106439. [PMID: 38048918 DOI: 10.1016/j.jsbmb.2023.106439] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 11/09/2023] [Accepted: 11/27/2023] [Indexed: 12/06/2023]
Abstract
Endometriosis was claimed to negatively affect the intrafollicular environment, hindering oocyte competence. Previous studies evaluated expression levels of cytochrome P450 aromatase (CYP19A) in granulosa and cumulus oophorus cells collected from endometriosis women, but results are controversial. To further investigate the intrafollicular environment whose alteration may potentially disturb ovarian steroidogenesis in endometriosis, gene expression of CYP19A and of its upstream enzymes, StAR and 3βHSD was assessed in luteinized granulosa cells isolated from follicular fluids (FF) collected during Assisted Reproduction Technology (ART) procedures in women with stage III-IV disease and from subjects without the condition. In a subgroup of patients, cumulus oophorus cells (COCs) were also assessed for CYP19A, StAR and 3βHSD gene expression. No difference in mRNA expression of CYP19A1, StAR and 3βHSD in both granulosa cells and COCs was observed between the two groups of patients. No significant difference was also found between estradiol FF levels detected in endometriosis patients (median=873, IQR=522-1221 ng/ml)) and control patients (median=878, IQR=609-1137 ng/ml). To gain more insight into the intrafollicular regulation of CYP19A in patients with endometriosis, associations between expression of the analyzed genes, systemic and follicular 17β-estradiol levels and ART outcomes were assessed. While in the control group, levels of CYP19A1, StAR and 3βHSD transcripts significantly correlated with follicular estradiol levels (adjusted R² of 0.60), no significant association was detected in affected women (adjusted R² of 0.23). After stratification of the populations based on the presence of the disease, CYP19A1 expression was shown to correlate with the number of oocytes retrieved [β:- 1.214;95%CI: - 2.085 - (-0.343); p = 0.007] in the control group while this association was not present in patients with endometriosis [β:- 0.003; 95%CI:- 0.468-0.461; p = 0.988)]. These results do not support data from the literature indicating a reduced aromatase expression in granulosa cells of affected women, but they highlight a potential subtle mechanism affecting the ovulation process in these women.

Abstract
BACKGROUND The aim of this study was to investigate late follicular progesterone (P) serum levels in women with a low number of preovulatory follicles in the assisted reproductive technologies (ART) setting. METHODS Fifty-five consecutive women having four or fewer preovulatory follicles of >14 mm on the day of human chorionic gonadotropin (hCG) administration were prospectively evaluated. Spearman correlation tests were performed between serum estradiol (E2) level, serum P level, P/E2 ratio, number of preovulatory follicles, oocytes and embryos. Women enrolled were further divided into two groups in accordance with the P/E2 ratio on the day of hCG administration and compared. RESULTS Serum E2 level correlated positively with P serum level (rs=0.36, P<0.01), number of mature follicles (rs=0.50, P<0.01) and number of oocytes retrieved (rs=0.36, P<0.05), whereas negatively with P/E2 ratio (rs=- 0.68, P<0.01). Likewise, number of preovulatory follicles correlated positively with E2 level (rs=0.50, P<0.01), P level (rs=0.27, P<0.05) and number of oocytes retrieved (rs=0.33, P<0.05), while it correlated negatively with P/E2 ratio (rs=-0.33, P<0.05). Furthermore, women with P/E2 ratio >1 on the day of hCG administration received considerably higher total follicular stimulating hormone (FSH) dosage and achieved significantly lower number of oocytes and embryos as compared to controls. CONCLUSIONS The reverse relationship between number of preovulatory follicles and P/E2 ratio implies that P rise is not only the result of increased steroidogenic activity, but other oocyte-follicle disrupted mechanisms seem to be involved. An exaggerated FSH stimulation appears to disrupt further these mechanisms.

Abstract
BACKGROUND Because often introduced without proper validation studies, so-called "add-ons" to IVF have adversely affected in vitro fertilization (IVF) outcomes worldwide. All-freeze cycles (embryo banking, EB) with subsequently deferred thaw cycles are such an "add-on" and, because of greatly diverging reported outcomes, have become increasingly controversial. Based on "modeling" with selected patient populations, we in this study investigated whether reported outcome discrepancies may be the consequence of biased patient selection. RESULTS In four distinct retrospective case control studies, we modeled in four cohort pairings how cryopreservation with subsequent thaw cycles affects outcomes differently in good-, average- and poor-prognosis patients: (i) 127 fresh vs. 193 frozen donor-recipient cycles to model best-prognosis patients; (ii) 741 autologous fresh non-donor IVF cycles vs. 217 autologous frozen non-donor IVF cycles to model average prognosis patients; (iii) 143 favorably selected autologous non-donor IVF cycles vs. the same 217 frozen autologous cycles non-donor to monitor good- vs. average-prognosis patients; and (iv) 598 average and poor-prognosis autologous non-donor cycles vs. the same 217 frozen autologous non-donor cycles to model poor vs. average prognosis patients. In best-prognosis patients, EB marginally improved IVF outcomes. In unselected patients, EB had no effects. In poor-prognosis patients, EB adversely affected IVF outcomes. Unexpectedly, the study also discovered independent-of-age-associated chromosomal abnormalities, a previously unreported effect of recipient age on miscarriage risk in donor-egg recipients. CONCLUSIONS In poor-prognosis patients, EB cycles should be considered contraindicated. In intermediate-prognosis patients EB does not appear to change outcomes, not warranting additional cost and time delays. Therefore, only good-prognosis patients are candidates for EB, though they will experience only marginal benefits that may not be cost-effective.

Abstract
Background To determine whether progestin-primed ovarian stimulation (PPOS) is more effective for women with diminished ovarian reserve (DOR) than clomiphene citrate (CC)/letrozole (LE) plus gonadotropin in IVF or ICSI treatment. Methods Nine databases were searched until May 24, 2023, to identify relevant studies. Forest plots were used to present the results of this meta-analysis. Begg's and Egger's tests were applied to estimate publication bias. Subgroup and sensitivity analysis were performed to check the potential sources of heterogeneity and verify the robustness of the pooled results, respectively. Results A total of 14 studies with 4182 participants were included for meta-analysis. There was evidence of a statistically notable increase in clinical pregnancy rate (OR = 1.39, 95%CI [1.01, 1.91], p = 0.05), optimal embryos rate (OR = 1.50, 95%CI [1.20, 1.88], p = 0.0004), and cumulative pregnancy rate (OR = 1.73, 95%CI [1.14, 2.60], p = 0.009), the duration and the amount of gonadotropin required (MD = 1.56, 95%CI [0.47, 2.66], p = 0.005; SMD = 1.51, 95%CI [0.90, 2.12], p < 0.00001), along with decrease cycle cancellation rate (OR = 0.78, 95%CI [0.64, 0.95], p = 0.02), luteinizing hormone (LH) level on the day of hCG (SMD = -0.81, 95%CI [-1.10, -0.53], p < 0.00001), and premature LH surge rate (OR = 0.10, 95%CI [0.07, 0.15], p < 0.00001) when PPOS was used. No evidence for publication bias within results was revealed. Conclusions Based on evidence-based results, PPOS protocol seems to improve IVF/ICSI outcomes for women with DOR. More research with larger sample sizes and rigorous designs are required to further explore the value of PPOS among women diagnosed with DOR.

Abstract
In current IVF practice, metaphase-2 (M2) oocytes are considered most efficient in producing good quality embryos. Maximizing their number at all ages is standard clinical practice, while immature germinal vesicle (GV) oocytes are mostly automatically discarded. We present preliminary evidence that oocyte maturity grades with advancing age significantly change in their abilities to produce good quality embryos, with M2 oocytes significantly declining, GV oocytes improving, and M1 oocytes staying the same. These data contradict the over-40-year-old dogma that oocyte grades functionally do not change with advancing age, supporting potential changes to current IVF practice: (1) Stimulation protocols and timing of oocyte retrieval can be adjusted to a patient's age and ovarian function. (2) In older and younger women with prematurely aging ovaries, GV oocytes may no longer be automatically discarded. (3) In some infertile women, rescue in vitro maturation of immature oocytes may delay the need for third-party egg donation.

Abstract
Maternal aging has been reported to reduce oocyte quality and, in turn, lower the developmental potential of the resulting embryos. Here, we show that maternally aged oocytes display two strikingly different phenotypes: some have normal morphology, whereas others have significantly shrunk cytoplasm. The latter phenotype usually prevails in aged females. Our objective was to characterize both types of maternally aged oocytes and investigate the origins of this diversity. Importantly, our experiments indicate that shrunk maternally aged oocytes are severely compromised in terms of mitochondrial functionality as compared to their young or morphologically normal maternally aged counterparts: they display significantly decreased mitochondrial activity and lower amounts of ROS. In contrast, morphologically normal maternally aged oocytes had the same mitochondrial activity as young ones, while their ROS levels were higher. Surprisingly, the shrunk phenotype was completely absent in maternally aged oocytes that matured in vitro, suggesting that it is not caused inherently by maternal aging, but may be related to other factors, like postovulatory aging. Indeed, an additional culture of in vitro matured young and old oocytes (i.e., in vitro postovulatory aging) significantly decreased their mitochondrial activity and led to cytoplasm shrinkage. In vivo postovulatory aging had a similar effect on oocytes from both young and old females. Finally, we examined the developmental potential of oocytes obtained from aged females. Shrunk (i.e., most likely postovulatory aged) oocytes failed to become fertilized, whereas morphologically normal ones (i.e., most likely not subjected to postovulatory aging) underwent fertilization and subsequent cleavage divisions, although they achieved the 2-cell stage less frequently than morphologically normal oocytes from young females. Importantly, the quality of blastocysts as well as the live birth rate for morphologically normal oocytes from old and young females were similar. In summary, our data clearly indicate that two pools of oocytes present in oviducts of aged females differ significantly in their quality and developmental potential and that the more severely affected phenotype results most likely from a synergistic action of maternal and postovulatory aging.

Abstract
This study is designed to investigate the effects of increased progesterone (P4) levels on the quality of retrieved oocytes and embryos during IVF. This retrospective analysis included 982 all-freezing in vitro fertilization (IVF) cycles (conducted between November 2019 and June 2020 at CHA Fertility Center Bundang, South Korea) in which serum P4 levels were measured on the day of human chorionic gonadotropin (hCG) administration. Our study revealed that the serum P4 levels on the day of hCG administration are strongly associated with the rates of oocyte maturation, displaying a positive correlation in patients with serum P4 < 2.25 ng/mL (p = 0.025). Moreover, patients with serum P4 < 1.25 ng/mL showed relatively low fertilization rates (p = 0.037), and the rates of good embryo retrieval were significantly increased with the serum P4 level < 1.5 ng/mL (p = 0.001). Interestingly, serum P4 level on the day of hCG administration affects the rate of good-quality embryo development, especially at the cleavage stage, and is associated with the status of ovarian responses. Our current study suggests that serum P4 level on the day of hCG administration negatively affects the rates of oocyte maturation, fertilization, and the development of good embryos.

Abstract
Abstract
STUDY QUESTION
Does intraovarian injection of platelet-rich plasma (PRP) change ovarian function in patients with extremely low functional ovarian reserve (LFOR) who, otherwise, would likely only have a chance of pregnancy through third-party oocyte donation?
SUMMARY ANSWER
No clinically significant effects of PRP treatment on ovarian function were observed over 1 year of follow-up.
WHAT IS KNOWN ALREADY
Several investigators have reported improved responses to ovulation induction after treatment with PRP. However, previous published reports have involved, at most, only small case series. Whether PRP actually improves ovarian performance is, therefore, still unknown. PRP is nevertheless widely offered as an ‘established’ fertility treatment, often under the term ‘ovarian rejuvenation’.
STUDY DESIGN, SIZE, DURATION
We are reporting a prospective cohort study of 80 consecutive patients at ages 28–54 with LFOR, defined by anti-Müllerian hormone <1.1 ng/ml, FSH >12 mIU/ml or at least one prior IVF cycle with ≤3 oocytes within 1 year. The women were followed for 1 year after an intraovarian PRP procedure.
PARTICIPANTS/MATERIALS, SETTING, METHODS
PRP (1.5 ml) was injected into the cortex of ovaries with an average of 12 injections per ovary. Study participants were followed every 3 days for 2 weeks after PRP treatment with estradiol and FSH measurements and vaginal ultrasound to observe follicle growth and thereafter followed weekly. Beginning 1 month after their PRP treatment, participants underwent one or more cycles of ovarian stimulation for IVF. Outcome measures were endocrine response, and numbers of oocytes and embryos produced in response to a maximal gonadotropin stimulation before and after PRP treatment.
MAIN RESULTS AND THE ROLE OF CHANCE
In this study, women failed to demonstrate statistically significant outcome benefits from intraovarian PRP. However, two 40-year-old very poor-prognosis patients, with prior failed IVF cycles that never reached embryo transfer at other centers, achieved pregnancy, resulting in an ongoing pregnancy rate of 4.7% among patients who, following PRP, produced at least one oocyte (n = 42).
LIMITATIONS, REASONS FOR CAUTION
As an observational study of patients who performed poorly in past ovarian stimulation cycles, the improvement may be accounted for by regression to the mean. Similar considerations may also explain the occurrence of the two pregnancies.
WIDER IMPLICATIONS OF THE FINDINGS
This study demonstrates that, even in extremely poor prognosis patients due to LFOR, sporadic pregnancies are possible. The study, however, does not allow for the conclusion that those pregnancies were the consequence of PRP treatments. A case series, indeed, does not allow for such conclusions, even if results are more suggestive than here. This registered study, therefore, must be viewed as a preliminary report, with further data expected from this study but also from two other prospectively randomized ongoing registered studies with more controlled patient selection.

[PMID: 35572405 PMCID: PMC9091735 DOI: 10.1016/j.jare.2021.09.001] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2021] [Revised: 09/01/2021] [Accepted: 09/03/2021] [Indexed: 01/25/2023] Open
Abstract
Mesenchymal stem cells transplantation (MSCs’) to the ovaries of POF patients could lead to effective clinical outcomes. Assessment of MSCs’ effect for single transplantation was performed using 3 transplantation methods. MSCs into ovaries by ovarian local injection was determined as the most effective route. This technique exerted marked effect on antagonizing age-associated ovarian hypofunction. Histopathological data showed that no neoplasms and obvious prosoplasia were found after MSCs transplantation.
Introduction The transplantation of mesenchymal stem cells (MSCs) in patients with premature ovarian failure (POF) could lead to clinical improvement. The transplantation to the ovaries among other transplantation methods have been reported in various animal models, however, there is little evidence regarding the optimal method, including the clinical safety and the efficiency for the treatment of age associated ovarian hypofunction. Objectives To establish the most effective transplantation route of MSCs, explore the resistance to therapy, its safety and role in the natural aging process of the ovaries. Methods Highly purified MSCs were injected intraperitoneally, directly into the ovaries or tail-intravenously in mice animal model. The ovarian function, quantity and quality of oocytes, cell viability/apoptosis, were evaluated, applying chemiluminescence analysis (CLIA), western blotting, immunofluorescence staining, transmission electron microscope (TEM), TdT mediated dUTP Nick End Labeling (TUNEL) assay and other techniques. The organ tumorigenicity was also evaluated by long-term observation and histopathological examination. The efficiency of MSCs was further verified in non-human primates by the most effective transplantation route. Results The 32nd week was ultimately determined as the time point of MSCs transplantation. Our results showed that the intra-ovarian injection was the best transplantation method with a more conspicuous effect. With deeper investigations, we found that the transplanted MSCs showed an effective influence on the follicular number, promoted follicle maturation and inhibited cell apoptosis, which was further verified in non-human primates. In addition, the long-term observation and the histopathological examinations ruled out neoplasms or obvious prosoplasia after MSCs transplantation. Conclusion MSCs transplantation by intra-ovarian injection could within a month exert the most conspicuous anti-age-associated ovarian hypofunction effects, which may improve the quantity and quality of oocytes by changing the mitochondrial structure, regulating mitochondrial function and attenuating cell apoptosis to increase the storage of the follicle pool without a remarkable potential of tumorigenicity.

Importance of IGF-I levels in IVF: potential relevance for growth hormone (GH) supplementation. J Assist Reprod Genet 2022; 39:409-416. [PMID: 35066698 PMCID: PMC8956770 DOI: 10.1007/s10815-021-02379-8] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/11/2021] [Accepted: 12/10/2021] [Indexed: 12/28/2022] Open
Abstract
Purpose Growth hormone (GH) supplementation in association with in vitro fertilization (IVF) is worldwide again increasing, even though study outcomes have been discrepant. Since GH acts via insulin-like growth factor-1 (IGF-1), its utilization in IVF would only seem to make sense with low IGF-1. We, therefore, determined whether IGF-I levels affect IVF outcomes. Methods Retrospectively, 302 consecutive first fresh, non-donor IVF cycles were studied, excluding patients on GH supplementation. Patients were divided into 3 subgroups: IGF-1 in lower 25th percentile (group A, < 132 ng/mL, n = 64); 25th–75th percentile (B, 133–202 ng/mL, n = 164), and upper 25th percentile (C, > 202 ng/mL, n = 74). IGF-1 was tested immunochemiluminometric with normal range at 78–270 ng/mL. Because of the study patients’ adverse selection and low pregnancy chances, the main outcome measure for the study was cycle cancellation. Secondary outcomes were oocyte numbers, embryos transferred, pregnancies, and live births. Results Group A was significantly older than B and C (P = 0.019). IGF-1 decreased with increasing age per year by 2.2 ± 0.65 ng/mL (P = 0.0007). FSH was best in group B and worst in A (trend, P = 0.085); AMH was best in B and worst in A (N.S.). Cycle cancellations were lowest in C (11.6%) and highest in A (25.0%; P = 0.042). This significance further improved with age adjustment (P = 0.021). Oocytes, embryo numbers, pregnancies, and live birth rates did not differ, though oocyte numbers trended highest in B. Conclusions Here presented results support the hypothesis that IGF-1 levels affect IVF outcomes. GH treatments, therefore, may be effective only with low IGF-1.

Abstract
OBJECTIVE To analyze the duration of gonadotropin hyperstimulation's impacts on oocyte quality and clinical outcomes in aged in vitro fertilization (IVF) patients. MATERIALS AND METHODS This retrospective study was carried out using IVF records of the Chang Gung Memorial Hospital IVF center from January 2017 to December 2019. A total of 308 IVF cycles with patients aged 40-44 years were included. Clinical characteristics of patients who received a short controlled ovarian hyperstimulation (COH) (i.e., 6-7 days; s-COH group) or a long COH treatment (i.e., 9-10 days; l-COH group) were compared. In addition, analysis was conducted using data within two age subgroups: 40-42 years and 42-44 years subgroups. RESULTS The s-COH group received significantly lower total doses of gonadotropin and had smaller leading follicles at the time of ovulation trigger when compared to the l-COH group. The s-COH group also produced a significantly lower number of oocytes, mature metaphase II (MII) oocytes, and 2 PN zygotes compared to the l-COH group. However, there was no significant difference in the number of transferable and good-quality embryos between the two treatment groups. Likewise, the pregnancy rate and live birth rate were comparable in the s-COH and l-COH groups. Similar results were obtained when the analysis was limited to select age subgroups (i.e., 40-42 and 42-44 years subgroups). CONCLUSION While a long COH generates more oocytes per cycle, a 6-7 days COH treatment, which is at the lower end of the recommended window of stimulation, could achieve a pregnancy outcome comparable to that applied 9-10 days of COH in aged patients.

Abstract
Objective To answer the question if the freeze-all strategy and subsequent frozen embryo transfer is preferable to fresh embryo transfer for patients with normal response to ovarian stimulation (4 to 15 oocytes recovered) during in vitro fertilization treatments. Methods A retrospective cohort from two human reproduction centers between 2013 and 2017. A total of 471 frozen embryo transfers from freeze-all cycles, and 3,208 fresh transfers were included. Results After propensity score matching adjustment for age and number of eggs, 467 freeze-all cycles and 934 fresh cycles were analyzed, revealing no statistically significant difference between groups in relation to clinical pregnancy rate (32.5% in the Freeze-all Group and 32.3% in the Fresh Group, p=0.936). For women aged 40 years and older, we observed a statistically significant higher clinical pregnancy rate when freeze-all strategy was used (29.3% in the Freeze-all Group and 19.8% in the Fresh Group, p=0.04). Conclusion Freeze-all strategy was not superior to fresh transfer for all patients with normal response to ovarian stimulation. However, women aged 40 years and older could benefit from this strategy. This deserves further investigation in future research, preferable in a prospective randomized study.

Double daily doses of cetrorelix may raise follicular phase progesterone more compared to single doses in poor ovarian response patients. J Gynecol Obstet Hum Reprod 2021; 50:102223. [PMID: 34509694 DOI: 10.1016/j.jogoh.2021.102223] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Revised: 08/26/2021] [Accepted: 09/05/2021] [Indexed: 10/20/2022]
Abstract
PURPOSE There is evidence that follicular phase progesterone rise [FPPR] adversely affects fresh in vitro fertilization [IVF] cycles. A single daily dose of cetrorelix has been used to prevent early luteinizing Hormone (LH) surge. We speculated that doubling the daily dose might have a positive effect in patients who have early LH surges despite receiving the single daily dose treatment. However, a double daily dose of cetrorelix seems to cause FPPR in poor ovarian response (POR) patients. MATERIALS AND METHODS On human chorionic gonadotropin [hCG] injection days, the progesterone levels of POR patients who received a single daily dose of cetrorelix (group 1, n = 59) were compared with progesterone levels of the patients who received a double daily dose of cetrorelix (group 2, n = 75). The two groups had statistically similar demographic data. The patients who had FPPR were detected, and a comparison of progesterone levels, using 0.8, 1.0, and 1.2 [ng/mL] of progesterone as cut-off levels, was made between patients of both groups. RESULTS FPPR patients in group 2 had significantly higher progesterone levels during hCG day, contrary to expectations. When progesterone cut-off levels of 0.8, 1.0, and 1.2 [ng/mL] were used for group 1 patients, 15.3%, 13.6%, and 6.8% of the patients developed FPPR, respectively When the progesterone cut-off levels of 0.8, 1.0, and 1.2 [ng/mL] were used for group 2, the results detected were 45.3%, 30.7%, and 21.3%, respectively. A significant statistical difference in progesterone levels was observed between the groups. CONCLUSION While the double daily dose of cetrorelix was initially thought to more effectively suppress early LH rise by some authors, we have seen that it increases the FPPR more when compared to a single daily dose regime. We suggest using frozen cycles instead of fresh cycles in order to have better endometrial receptivity in patients who seem to benefit from higher daily doses of cetrorelix.

Abstract
Objectives Progestin-primed ovarian stimulation (PPOS) is a new ovarian stimulation protocol that can block the luteinizing hormone (LH) surge through progesterone instead of traditional down regulating or gonadotropin-releasing hormone (GnRH) antagonist, and in order to achieve multi-follicle recruitment. This paper aims to investigate the effectiveness of PPOS and its suitability for infertile patients with different ovarian reserve functions. Methods We searched published randomized controlled trials (RCTs) about PPOS on Cochrane Library, PubMed, Embase, and Web of Science. The search period spanned from January 1, 2015 to November 16, 2020. The data were extracted, and the meta-analysis was performed on ovarian stimulation as well as embryological and clinical outcomes. The outcomes were pooled by a random effects model, and the risk of heterogeneity was evaluated. Subgroup analysis was performed for different ovarian reserve patients. Results The clinical pregnancy rates and live birth or ongoing pregnancy rates with the PPOS protocol were not different from those with the control group. In the diminished ovarian reserve (DOR) subgroup, the PPOS protocol had a lower rate of premature LH surge [RR = 0.03, 95% CI = 0.01 to 0.13, p < 0.001]. The PPOS protocol had a lower rate of ovarian hyperstimulation syndrome (OHSS) [RR = 0.52, 95% CI = 0.36 to 0.76, p < 0.001, I2 = 0.00%]. The secondary outcomes showed that the number of oocytes retrieved, MII oocytes, and viable embryos was higher than that of the control protocol in DOR patients [(MD = 0.33, 95% CI = 0.30 to 0.36, p < 0.001), (MD = 0.30, 95% CI = 0.27 to 0.33, p < 0.001), (MD = 0.21, 95% CI = 0.18 to 0.24, p < 0.001)] and normal ovarian reserve (NOR) patients [(MD = 1.41, 95% CI = 0.03 to 2.78, p < 0.001), (MD = 1.19, 95% CI = 0.04 to 2.35, p < 0.001), (MD = 1.01, 95% CI = 0.21 to 1.81, p = 0.01)]. Conclusion The findings suggest that PPOS is an effective ovarian stimulation protocol and is beneficial for patients with different ovarian reserve functions, which needs to be validated in more RCTs with larger samples.

The m6A mRNA demethylase FTO in granulosa cells retards FOS-dependent ovarian aging. Cell Death Dis 2021; 12:744.

Abstract
Multifunctional N6-methyladenosine (m6A) has been revealed to be an important epigenetic component in various physiological and pathological processes, but its role in female ovarian aging remains unclear. Thus, we demonstrated m6A demethylase FTO downregulation and the ensuing increased m6A in granulosa cells (GCs) of human aged ovaries, while FTO-knockdown GCs showed faster aging-related phenotypes mediated. Using the m6A-RNA-sequence technique (m6A-seq), increased m6A was found in the FOS-mRNA-3'UTR, which is suggested to be an erasing target of FTO that slows the degradation of FOS-mRNA to upregulate FOS expression in GCs, eventually resulting in GC-mediated ovarian aging. FTO acts as a senescence-retarding protein via m6A, and FOS knockdown significantly alleviates the aging of FTO-knockdown GCs. Altogether, the abovementioned results indicate that FTO in GCs retards FOS-dependent ovarian aging, which is a potential diagnostic and therapeutic target against ovarian aging and age-related reproductive diseases.

Abstract
OBJECTIVE The aim of this retrospective case-control study was to analyze the effect of administering indomethacin after triggering final oocyte maturation in patients with poor ovarian response (POR) on the cycle cancellation rate due to premature ovulation (PO), the number of oocytes retrieved and the clinical outcomes of IVF cycles. STUDY DESIGN A total of 214 patients with POR, diagnosed according to the Bologna criteria, who underwent fresh IVF cycle via flexible gonadotrophin-releasing hormone antagonist (GnRH-ant) protocol were enrolled in the study. The control group consisted of 100 patients, whereas the indomethacin group included 114 patients who received 100 mg rectal indomethacin administered twice within the same day (twelve hours apart) -starting at twelve hours after triggering. Cycle cancelation rates (CCR), number of oocytes retrieved (nOR), implantation rates (IR), biochemical pregnancy (BP) and clinical pregnancy loss rates (CPL), ongoing pregnancy rates (OPR) and live birth rates (LBR) were compared between the indomethacin and control groups. RESULTS The CCR rate was significantly lower in the indomethacin group (1.8%) compared to the control group (1.8% vs %12%, p = 0.01). In the control group, those with cycle cancellation were older than those without cycle cancellation (mean age 42.2 ± 2.3 years vs. 39.36 ± 4.3 years, p = 0.001) and had lower anti-Müllerian hormone levels and lower antral follicle count (0.59 ± 0.2 ng/mL vs 0.79 ± 0.2 ng/mL, p = 0.001 and 4 ± 0.6 vs 5.7 ± 1.7, p = 0.001, respectively). In multivariable analysis, when the dependent variable in the logistic regression model was coded as the absence of cycle cancellation, it was observed that only indomethacin had a statistically significant effect on cycle cancellation (β = -1.931, standard error = 0.832, Exp(B) = 0.145, p = 0.020). nOR was higher in the indomethacin group than control group but the difference did not reach significance (p = 0.07). Moreover, the IR, OPR and LBR, BP and CPL values were similar in the indomethacin and control groups (p > 0.05). CONCLUSIONS Based on data from this study, it can be concluded that indomethacin reduces cycle cancelation due to PO in patients with POR -without compromising implantation and pregnancy rates. However, further randomized controlled trials with larger sample sizes are required to clarify the definitive effect of indomethacin in the treatment of patients with POR.

Endocrine 2021; 72:260-267. [PMID: 33009651 DOI: 10.1007/s12020-020-02512-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2020] [Accepted: 09/23/2020] [Indexed: 10/23/2022]
Abstract
BACKGROUND Mediated via the androgen receptor on granulosa cells, models of small growing follicle stages demonstrate dependence on testosterone. Androgen deficiency reduces ovarian response to follicle stimulation hormone (FSH), granulosa cell mass and estradiol (E2) production falls and FSH, therefore, rises. Though potentially of adrenal and/or ovarian origin, androgen deficiency in association with female infertility is almost universally primarily of adrenal origin, raising the possibility that women with presumptive diagnosis of primary ovarian insufficiency (POI), also called primary ovarian failure (POF) may actually suffer from secondary ovarian insufficiency (SOI) due to adrenal hypoandrogenism that leads to follicular arrest at small-growing follicle stages. METHODS This retrospective cohort study was performed in a private, academically affiliated infertility center in New York City. We searched the center's anonymized electronic research data bank for consecutive patients who presented with a diagnosis of POI, defined by age <41 year, FSH > 40.0 mIU/mL, amenorrhea for at least 6 month, and low testosterone (T), defined as total T (TT) in the lowest age-specific quartile of normal range. This study did not include patients with oophoritis. Since dehydroepiandrosterone sulfate (DHEAS) is the only androgen almost exclusively produce by adrenals, adrenal hypoandrogenism was defined by DHEAS < 100ug/dL. Thirteen of 78 presumed POI women (16.67%) qualified and represented the original study population. POI patients are usually treated with third-party egg donation; 6/13, however, rejected egg donation for personal or religious reasons and insisted on undergoing at least one last IVF cycle attempt (final study population). In preparation, they were supplemented with DHEA 25 mg TID and CoQ10 333 mg TID for at least 6 weeks prior to ovarian stimulation for IVF with FSH and human menopausal gonadotropins (hMG). Since POI patients are expected to be resistant to ovarian stimulation, primary outcome for the study was ovarian response, while secondary outcome was pregnancy/delivery. RESULTS Though POI/POF patients usually are completely unresponsive to ovarian stimulation, to our surprise, 5/6 (83.3%) patients demonstrated an objective follicle response. In addition, 2/6 (33.3%) conceived spontaneously between IVF cycles, while on DHEA and CoQ10 supplementation and delivered healthy offspring. One of those is currently in treatment for a second child. CONCLUSIONS This preliminary report suggests that a surprising portion of young women below age 41, tagged with a diagnosis of POI/POF, due to adrenal hypoandrogenism actually suffer from a form of SOI, at least in some cases amenable to treatment by androgen supplementation. Since true POI/POF usually requires third-party egg donation, correct differentiation between POI and SOI in such women appears of great importance and may warrant a trial stimulation after androgen pre-supplementation for at least 6 weeks.

D-Chiro-Inositol Treatment Affects Oocyte and Embryo Quality and Improves Glucose Intolerance in Both Aged Mice and Mouse Models of Polycystic Ovarian Syndrome. Int J Mol Sci 2020; 21:E6049. [PMID: 32842637 PMCID: PMC7504697 DOI: 10.3390/ijms21176049] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2020] [Revised: 08/17/2020] [Accepted: 08/20/2020] [Indexed: 12/15/2022] Open
Abstract
Polycystic ovarian syndrome (PCOS) is the main cause of female infertility. It is a multifactorial disorder with varying clinical manifestations including metabolic/endocrine abnormalities, hyperandrogenism, and ovarian cysts, among other conditions. D-Chiro-inositol (DCI) is the main treatment available for PCOS in humans. To address some of the mechanisms of this complex disorder and its treatment, this study examines the effect of DCI on reproduction during the development of different PCOS-associated phenotypes in aged females and two mouse models of PCOS. Aged females (8 months old) were treated or not (control) with DCI for 2 months. PCOS models were generated by treatment with dihydrotestosterone (DHT) on Days 16, 17, and 18 of gestation, or by testosterone propionate (TP) treatment on the first day of life. At two months of age, PCOS mice were treated with DCI for 2 months and their reproductive parameters analyzed. No effects of DCI treatment were produced on body weight or ovary/body weight ratio. However, treatment reduced the number of follicles with an atretic cyst-like appearance and improved embryo development in the PCOS models, and also increased implantation rates in both aged and PCOS mice. DCI modified the expression of genes related to oocyte quality, oxidative stress, and luteal sufficiency in cumulus-oocyte complexes (COCs) obtained from the aged and PCOS models. Further, the phosphorylation of AKT, a main metabolic sensor activated by insulin in the liver, was enhanced only in the DHT group, which was the only PCOS model showing glucose intolerance and AKT dephosphorylation. The effect of DCI in the TP model seemed mediated by its influence on oxidative stress and follicle insufficiency. Our results indicate that DCI works in preclinical models of PCOS and offer insight into its mechanism of action when used to treat this infertility-associated syndrome.

Abstract
Based on national registry reports, after age 42, the number of IVF cycles utilizing autologous oocytes is very small; after age 43, autologous oocyte use in US IVF cycles is almost non-existent. We here argue that the in vitro fertilization (IVF) field has created a self-fulfilling prophecy by basically abandoning the utilization of autologous oocytes after ages 42-43 years. This not only resulted in almost no IVF cycles with autologous oocytes being performed but also in abandonment of research that could lead to improvements in IVF outcomes in older women when using autologous oocytes. As a consequence, IVF has largely stagnated in this area. We further argue that third-party oocyte donation in clinical IVF should be considered a treatment failure, as it requires patients to choose a second rather than a first-choice treatment. Such a redesignation of third-party egg donation would not only be appropriate but could lead to necessary changes in physician attitudes, considering that women almost exclusively prefer to conceive with their autologous oocytes.

Abstract
BACKGROUND Previous studies have demonstrated that progestin-primed ovarian stimulation (PPOS) protocol was a feasible and efficient method in in vitro fertilization (IVF) cycle. However, its application in women with advanced age has not been determined yet. The purpose of this study was to investigate its efficacy in women aged ≥40 years old. METHODS This retrospective cohort study included patients with ages of ≥40 years old at the time of ovarian stimulation. The embryonic and clinical outcome of mild stimulation and PPOS were compared. Primary outcome was top-quality embryo rate on day 3, and secondary outcome was clinical pregnancy rate. RESULTS Baseline characteristics of patients was similar in mild stimulation (122 cycles) and PPOS (47 cycles). No significant difference was found in the number of retrieved and mature oocytes and the fertilization and cleavage rates. Of interest, the rate of top-quality embryos was significantly higher in PPOS group (50.08% vs 33.29%, p = 0.015), with an increasing trend of viable embryo rate (73.55% vs 61.16%). A greater amount of gonadotropin was observed in PPOS group (2061.17 ± 1254.63 IU vs 1518.14 ± 547.25 IU, p < 0.05) in spite of comparable duration of stimulation. After FET cycle, no significant difference was found in the clinical pregnancy rates between mild stimulation (12.5%) and PPOS group (16.7%). CONCLUSIONS Higher percentage of top-quality embryos on Day 3 and comparable clinical pregnancy rate was obtained in PPOS protocol, which could be considered as a feasible ovarian stimulation protocol in women aged above 40 years old.

Abstract
The impact of the prematurely elevated serum progesterone on the late follicular phase, commonly known as premature luteinization (PL), is a matter of continuing debate. Available evidence supports that serum progesterone ≥ 1.5 ng/ml on the day of ovulation triggering could reduce the pregnancy potential in fresh in vitro fertilization (IVF) cycles by jeopardizing endometrial receptivity. Causes of PL during ovarian stimulation are unclear. Recent studies point toward the daily follicle-stimulating hormone dosage, duration of controlled ovarian stimulation, number of oocytes retrieved, and peak estradiol level as factors affecting the incidence of PL. Emerging data show additional influence on embryo quality. The prevention of PL has been challenging. The key elements in preventing PL include individualization of ovarian stimulation according to patient's ovarian reserve, proper ovulation trigger timing, and use of medications such as corticosteroids and metformin. Embryo cryopreservation with deferred embryo transfer is the established strategy to overcome PL, yet it is an extra burden to the IVF laboratory and increased cost for patients. Herein, we review the up-to-date knowledge of this frequent IVF problem including causes, proposed diagnostic criteria, and its impact on endometrial receptivity, embryo quality, and pregnancy outcomes. The preventive measures and rescue strategies are also discussed.

Age, body weight and ovarian function affect oocyte size and morphology in non-PCOS patients undergoing intracytoplasmic sperm injection (ICSI). PLoS One 2019; 14:e0222390.

Abstract
The size of oocytes was previously reported to be smaller in obese women with polycystic ovary syndrome (PCOS). In the present prospective cohort study, we sought to determine whether oocyte size and morphology are associated with patient characteristics in non-PCOS women. Oocyte and oolemmal diameter were measured, enlarged perivitelline space (PVS) and ooplasmic granulation were assessed in 308 MII oocytes from 77 IVF/ICSI couples. Statistical analysis was undertaken using SAS version 9.4 (SAS institute Inc., USA). Continuous values are presented as mean ± SD and compared using a two-sample t-test or Mann-Whitney U test as appropriate. Categorical parameters are presented as proportions and compared using a Fisher exact test. Logistic and linear regression models were used to control for the effect of age for categorical and continuous variables respectively. P-value < 0.05 was considered statistically significant. Patients presented with a mean age of 40.3±5.0 years, had a BMI of 25.1±6.1 kg/m2, median AMH levels of 0.6 ng/ml and produced a median of 4 oocytes. Mean total oocyte diameter was 163.2±7.4 μm (range 145.8–182.1 μm), while oolemmal diameter was 109.4±4.1 μm (range 98.5–122.3 μm). After adjusting for age and ovarian reserve increasing BMI was associated with decreased total oocyte diameter (p<0.05). Total oocyte diameter was also inversely associated with AMH levels (p = 0.03) and oocyte yield (p = 0.04). In contrast to total oocyte diameter, oolemmal diameter was not related to patient characteristics. Younger women and those with large oocyte yields demonstrated fewer oocytes with ooplasmic granulation (p<0.05 and p = 0.01). After adjustments for age, ooplasmic granulation was also less frequently observed in oocytes from women with higher AMH (p = 0.03) and increasing BMI (p<0.01). Fertilization was more likely in oocytes with larger oolemmal diameter (p = 0.008). Embryos from oocytes with larger total and ooplasmic diameters were more likely to be transferred or frozen (p = 0.004 and p = 0.01). In non-PCOS infertile women, BMI and ovarian function relate to total oocyte diameter. These results expand on previously observed associations between oocyte size and BMI in women with PCOS. They indicate the importance of detailed oocyte assessments, which may aid the currently used criteria for embryo selection and help to better understand how oocyte status is associated with later embryo development.

Abstract
OBJECTIVE The aim of this study was to investigate cumulative live birth rate (CLBR) per oocyte retrieval cycle and per patient in women over 40 years old undergoing IVF/ICSI treatments, stratified for age, ovarian response and oocyte retrieval cycle number. MATERIALS AND METHODS 244 patients with poor ovarian response (POR) and 372 patients with normal ovarian response (NOR) were retrospectively investigated. RESULTS Of the patients aged 40 to 43 years, CLBR per oocyte retrieval cycle and per patient (4.3%; 8.8%) in POR group were both lower than those in NOR group (15.8%; 24.8%) (P < 0.01). No significant differences in live birth rate (LBR) per oocyte retrieval cycle or CLBR per patient were observed in the group of POR patients irrespective of oocyte retrieval cycles they underwent. Similarly, CLBR per patient in NOR group did not increase significantly with the oocyte retrieval cycle number. However, LBR per oocyte retrieval cycle in the first cycle (Cycle 1, 20.3%) was significantly higher than that in the second cycle (Cycle 2, 9.2%) and the third cycle (Cycle 3, 4.4%) (P < 0.01). And 94.8% (73/77) of live births were achieved during the first two cycles. Of the patients aged 44 to 45 years and over 45 years old, there were no significant differences in CLBR per oocyte retrieval cycle or per patient between POR and NOR groups. CONCLUSION Relatively higher cumulative live birth rate was only found in the patients aged 40 to 43 years without poor ovarian response. These findings may provide some information that further sub-classification of advance-age women according to ovarian response may help both clinicians and patients to balance decision-making about their infertility treatment.

The role of progesterone/estradiol ratio in exploring the mechanism of late follicular progesterone elevation in low ovarian reserve women. Med Hypotheses 2019; 125:126-128. [PMID: 30902140 DOI: 10.1016/j.mehy.2019.02.047] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2018] [Revised: 02/04/2019] [Accepted: 02/27/2019] [Indexed: 11/22/2022]
Abstract
Late follicular progesterone (P) elevation continues to complicate a significant part of assisted reproductive technologies (ART) cycles, despite the ardent employment of gonadotropin releasing hormone (GnRH) analogues. In women with good ovarian reserve, late follicular P elevation is believed to be the result of the controlled ovarian stimulation (COS) itself, multiple follicular development and excessive ovarian steroidogenic activity. These mechanisms do not seem to be plausible in women with low ovarian reserve. In these women, excessive COS achieve a small number of pre-ovulatory follicles, which is not coupled to considerable ovarian steroidogenic activity. Therefore, other mechanisms should be pursued and explored. Delicate paracrine and autocrine mechanisms within the oocyte-cumulus complex were suggested to preserve the integrity of the pre-ovulatory follicle, including inhibition of P increase and follicular luteinization. However, clinical studies to demonstrate the disruption of these mechanisms in cases with low ovarian reserve and ageing oocytes are still lacking. Late follicular progesterone/estradiol (P/E2) ratio was introduced into clinical practice as a more appropriate way to analyze P rise in women undergoing COS to control for the E2 increase. The current hypothesis claims that in a follicular environment were the mechanism that prevent premature luteinization is disrupted, independent to LH surge; P rise at the late follicular phase may relatively bypass normal E2 production, at the pre-ovulatory stage of steroidogenesis, causing a rise in the P/E2 ratio. Therefore, in women with low ovarian reserve and few pre-ovulatory follicles, undergoing conventional COS, a negative (reverse) correlation between number of maturing follicles and P/E2 ratio may support the existence of such a mechanism as its disruption, while a no or a positive correlation may disapprove it.

Abstract
BACKGROUND Progress in vitrification techniques has allowed reproductive physicians to consider new strategies for using progestin as an alternative to a GnRH analogue to improve in vitro fertilisation (IVF). However, the role of progestin in blocking luteinising hormone (LH) surges and its potential in clinical practice are unclear, especially for poor responders. We designed a prospective randomised controlled trial (RCT) to compare the efficacy of a gonadotropin-releasing hormone (GnRH) antagonist and progestin in blocking LH surges and premature ovulation in poor responders. METHODS/DESIGN Poor responders who meet the Bologna criteria will be randomised to one of two stimulation regimens-gonadotropin-releasing hormone (GnRH) antagonist or progestin-primed ovarian stimulation (PPOS)-using a computer-generated random number. Fresh embryos were transferred in the GnRH antagonist group and frozen embryos were transferred in the PPOS group. The primary outcome is the incidence of premature LH surges. Secondary outcomes include the number of oocytes retrieved, the number of embryos available for transfer, implantation rates and clinical pregnancy. The sample size for this trial is estimated as 340 participants, with 170 participants in each group. The data analysis will be by intention to treat. DISCUSSION To our knowledge, this is the first RCT to examine the efficacy of administering progestin orally to block LH surges and premature ovulation compared with the GnRH antagonist protocols in poor responders undergoing IVF treatment.

Abstract
PURPOSE Premature luteinization (PL) affects 12.3-46.7% of fresh in vitro fertilization cycles, and there is accumulating evidence confirming its negative effect on success rates. However, despite its clinical significance, PL is poorly understood and defined. This narrative review aims to provide a fresh look at the phenomenon of PL by summarizing the existing evidence and re-evaluating fundamental issues. METHODS A thorough electronic search was conducted covering the period from 1978 until January 2018 in PubMed, Embase, and Medline databases, and references of relevant studies were cross-checked. Meeting proceedings of the European Society of Human Reproduction and Embryology and the American Society for Reproductive Medicine were also hand searched. RESULTS In the curious case of PL, one should go back to the beginning and re-consider every step of the way. The pathogenesis, definition, measurement methods, clinical implications, and management strategies are discussed in detail, highlighting controversies and offering "food for thought" for future directions. CONCLUSIONS Authors need to speak the same language when studying PL in order to facilitate comparisons. The terminology, progesterone cut-off, measurement methods and days of measurement should be standardized and globally accepted; otherwise, there can be no scientific dialog. Future research should focus on specific patient profiles that may require a tailored approach. Progesterone measurements throughout the follicular phase possibly depict the progesterone exposure better than an isolated measurement on the day of hCG. Adequately powered randomized controlled trials should confirm which the best prevention and management plan of PL is, before introducing any strategy into clinical practice.

Abstract
RESEARCH QUESTION What level of IVF pregnancy success is currently possible in women of extremely advanced age? DESIGN This study reports on outcomes in women aged 43-51 years at the Centre for Human Reproduction, an academically affiliated private clinical fertility and research centre in New York City. RESULTS During the study years of 2014-2016, 16 pregnancies were established, all through day 3 transfers. Based on 'intent to treat' (cycle start), clinical pregnancy rates were 4/190 (2.1%), 5/234 (2.1%) and 7/304 (2.3%) and live birth rates were 2/190 (1.1%), 1/234 (0.43%) and 4/304 (1.3%) in 2014, 2015 and 2016, respectively. With reference to embryo transfer, clinical pregnancy rates were 4/140 (2.9%), 5/159 (3.1%) and 7/167 (4.2%) and live birth rates were 2/140 (1.4%), 1/159 (0.63%) and 4/167 (2.4%) for the same years. The results for 2016 also included what are probably the two oldest autologous IVF pregnancies ever reported in the literature. These results were obtained with patient ages, percentage of cycle cancellations and other adverse outcome parameters steadily increasing year by year. CONCLUSIONS Female age above 42 is widely viewed as the ultimate barrier to conception with IVF. Data reported here, although small and preliminary, demonstrate that potential outcomes are better than widely perceived, while pregnancy and live birth rates remain significantly inferior to donor egg recipient cycles. However, for selected women at very advanced ages, especially with higher egg/embryo numbers, autologous oocyte IVF offers a better option than widely acknowledged, if they are given individualized age-specific care.

Abstract
This paper serves to fill a gap in the literature regarding evidence for the use of botanical remedies in the promotion of fertility. It examines the botanical remedies that were used in North America (1492-1900) for all stages of reproduction from preconception to birth, and discusses their potential for future use with present-day infertility treatments. Each medicinal plant discussed in this paper is assessed using an ethnomedicinal methodology that entails examining the published ethnobotanical, phytochemical and pharmacological data. A few clinical trials have shown that there is potential for medicinal plants to improve the success rate of assisted reproductive technology (ART) treatment if used in an integrated manner, similar to the integrated use of traditional Chinese medicine with ART treatment. For example, research has shown that older women who become pregnant have a high miscarriage rate, and this is one area that complementary and alternative medicines can address.

Abstract
Human female reproductive aging features declining ovarian follicle reserve and oocyte quality, and rising levels of circulating follicle-stimulating hormone (FSH). We determined the effects of elevated FSH on oocyte-embryo development in mature mice exhibiting premature infertility caused by progressively rising transgenic human FSH (TgFSH) levels. Oocyte-embryo developmental competence and quality were examined using oocyte maturation and aneuploidy rates, biomarkers of oocyte quality, and reciprocal embryo transfers assessed for implantation and pregnancy. In vitro maturation suggested that TgFSH exposure only hindered oocyte developmental competence in old females, as significantly more oocytes from ≥12-month-old TgFSH females remained at germinal vesicle stage compared with age-matched control oocytes. Aneuploidy rates were equivalent in oocytes from aging TgFSH compared with wildtype females. Cumulus cell expression levels of candidate biomarker Inhba, Egfr, and Rgs2 transcripts were elevated in associated aneuploid vs euploid oocytes from both TgFSH and wildtype females. In vivo, embryos transferred from subfertile 6-month-old TgFSH females to wildtype recipients yielded normal implantation rates and more pups born compared with controls. Transfer of wildtype embryos rescued the fertility of 6-month-old TgFSH-recipient females, although pup birth weight was reduced in TgFSH vs wildtype recipients. Our current findings show that elevated FSH had minimal disruption of either embryo developmental capacity or uterine function when examined in isolation, and the subfertility of TgFSH female mice was not caused by altered oocyte aneuploidy or quality.

With low ovarian reserve, Highly Individualized Egg Retrieval (HIER) improves IVF results by avoiding premature luteinization. J Ovarian Res 2018; 11:23. [PMID: 29548330 PMCID: PMC5857093 DOI: 10.1186/s13048-018-0398-8] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2018] [Accepted: 03/13/2018] [Indexed: 01/06/2023] Open
Abstract
Background Highly Individualized Egg Retrieval (HIER), defined as age-specific early oocyte retrieval (ER), has been demonstrated to avoid premature luteinization in women ≥43. We here investigated whether HIER also applies to younger women with premature ovarian aging (POA), and what best lead follicle size should be for administration of ovulation-triggers. Methods Fifty-six women ≥43, and 37 POA patients underwent IVF cycles. Granulosa cells (GCs) were isolated, cultures were established, RNA was extracted and real-time PCR analyses performed, with gene expressions at mRNA level investigated for FSH receptor (FSHR), luteinizing hormone receptor (LHCPR), P450 aromatase (CYP19a1) and progesterone receptor (PGR). POA was defined by age < 40, FSH above 95%CI and/or AMH below 95%CI for age. Women ≥43 years were divided into very early retrieval (VER), with human chorionic gonadotropin (hCG) trigger at 13.5–15.5 mm, ER at 16.0–18.0 mm or standard retrievel (SR) at 18.5–20.5 mm; POA patients were divided into ER and SR. Pregnancy rates and and molecular markers of premature luteinization (PL) were main outcome measures. Results ER resulted in a significantly higher clinical pregnancy rate (16.7%) than VER (5.9%) or SR (6.7%; both P < 0.05). Molecular markers of PL were highest with SR and lowest with VER. In POA, ER improved pregnancy chances even more than in women ≥43 (7.7% with SR vs. 41.7% with ER), while also reducing molecular markers of PL. With low ovarian reserve (LOR), by avoiding PL, ER with hCG trigger at 16.0–18.0 mm, thus, improves clinical pregnancy rates at all ages. As VER demonstrated lowest molecular PL marker but equally poor pregnancy rates as SR, too early ovulation triggers, likely, result in cytoplasmatic immaturity. Conclusions HIER is even more effective in POA patients than women above age 43, demonstrating that HIER should be further investigated going into even more advanced ages.

Abstract
STUDY QUESTION What effect does multigenerational (F2) and transgenerational (F3) cigarette smoke exposure have on female fertility in mice? SUMMARY ANSWER Cigarette smoking has a multigenerational effect on female fertility. WHAT IS KNOWN ALREADY It has been well established that cigarette smoking decreases female fertility. Furthermore, a growing body of evidence suggests that smoking during pregnancy decreases the fertility of daughters and increases cancer and asthma incidence in grandchildren and great-grandchildren. STUDY DESIGN, SIZE, DURATION Six-week-old C57BL/6 female mice were exposed nasally to cigarette smoke or room air (controls) for 5 weeks prior to being housed with males. Females continued to be exposed to smoke throughout pregnancy and lactation until pups were weaned. A subset of F1 female pups born to these smoke and non-smoke exposed females were bred to create the F2 grandmaternal exposed generation (multigenerational). Finally, a subset of F2 females were bred to create the F3 great-grandmaternal exposed generation (transgenerational). The reproductive health of F2 and F3 females was examined at 8 weeks and 9 months. PARTICIPANTS/MATERIALS, SETTING, METHODS Ovarian and oocyte quality was examined in smoke exposed and control animals. A small-scale fertility trial was performed before ovarian changes were examined using ovarian histology and immunofluorescence and/or immunoblotting analysis of markers of apoptosis (TUNEL) and proliferation (proliferating cell nuclear antigen (PCNA) and anti-Mullerian hormone (AMH)). Oocyte quality was examined using immunocytochemistry to analyze the metaphase II spindle and ploidy status. Parthenogenetic activation of oocytes was used to investigate meiosis II timing and preimplantation embryo development. Finally, diestrus hormone serum levels (FSH and LH) were quantified. MAIN RESULTS AND THE ROLE OF CHANCE F2 smoke exposed females had no detectable change in ovarian follicle quality at 8 weeks, although by 9 months ovarian somatic cell proliferation was reduced (P = 0.0197) compared with non-smoke exposed control. Further investigation revealed changes between control and smoke exposed F2 oocyte quality, including altered meiosis II timing at 8 weeks (P = 0.0337) and decreased spindle pole to pole length at 9 months (P = 0.0109). However, no change in preimplantation embryo development was observed following parthenogenetic activation. The most noticeable effect of cigarette smoke exposure was related to the subfertility of F2 females; F2 smoke exposed females displayed significantly increased time to conception (P = 0.0042) and significantly increased lag time between pregnancies (P = 0.0274) compared with non-smoke exposed F2 females. Conversely, F3 smoke exposed females displayed negligible oocyte and follicle changes up to 9 months of age, and normal preimplantation embryo development. LARGE SCALE DATA None. LIMITATIONS, REASONS FOR CAUTION This study focused solely on a mouse model of cigarette smoke exposure to simulate human exposure. WIDER IMPLICATIONS OF THE FINDINGS Our results demonstrate that grandmaternal cigarette smoke exposure reduces female fertility in mice, highlighting the clinical need to promote cessation of cigarette smoking in pregnant women. STUDY FUNDING/COMPETING INTEREST(S) This study was funded by the Australian Research Council, National Health and Medical Research Council, Hunter Medical Research Institute, Newcastle Permanent Building Society Charitable Trust, and the University of Newcastle Priory Research Centers in Chemical Biology, Healthy Lungs and Grow Up Well.

Human amniotic mesenchymal stem cells improve ovarian function in natural aging through secreting hepatocyte growth factor and epidermal growth factor. Stem Cell Res Ther 2018.

Abstract
Background Although many reports show that various kinds of stem cells have the ability to recover function in premature ovarian aging, few studies have looked at stem cell treatment of natural ovarian aging (NOA). We designed this experimental study to investigate whether human amniotic mesenchymal stem cells (hAMSCs) retain the ability to restore ovarian function, and how hAMSCs work in this process. Methods To build the NOA mouse model, the mice were fed for 12–14 months normally with young fertile female mice as the normal control group (3–5 months old). Hematoxylin and eosin staining permitted follicle counting and showed the ovarian tissue structure. An enzyme-linked immunosorbent assay was used to detect the serum levels of the sex hormones estradiol (E2), anti-mullerian hormone (AMH), and follicle-stimulating hormone (FSH). The proliferation rate and marker expression level of human ovarian granule cells (hGCs) (ki67, AMH, FSH receptor, FOXL2, and CYP19A1) were measured by flow cytometry (FACS). Cytokines (growth factors) were measured by a protein antibody array methodology. After hepatocyte growth factor (HGF) and epidermal growth factor (EGF) were co-cultured with hGCs, proliferation (ki67) and apoptosis (Annexin V) levels were analyzed by FACS. After HGF and EGF were injected into the ovaries of natural aging mice, the total follicle numbers and hormone levels were tested. Results After the hAMSCs were transplanted into the NOA mouse model, the hAMSCs exerted a therapeutic activity on mouse ovarian function by improving the follicle numbers over four stages. In addition, our results showed that hAMSCs significantly promoted the proliferation rate and marker expression level of ovarian granular cells that were from NOA patients. Meanwhile, we found that the secretion level of EGF and HGF from hAMSCs was higher than other growth factors. A growth factor combination (HGF with EGF) improved the proliferation rate and inhibited the apoptosis rate more powerfully after a co-culture with hGCs, and total follicle numbers and hormone levels were elevated to a normal level after the growth factor combination was injected into the ovaries of the NOA mouse model. Conclusions These findings provide insight into the notion that hAMSCs play an integral role in resistance to NOA. Furthermore, our present study demonstrates that a growth factor combination derived from hAMSCs plays a central role in inhibiting ovarian aging. Therefore, we suggest that hAMSCs improve ovarian function in natural aging by secreting HGF and EGF.

Front Endocrinol (Lausanne) 2018; 9:767.

Abstract
Gonadotropin-releasing hormone antagonist (GnRH-ant) has been shown to negatively influence endometrial receptivity. Reducing the GnRH-ant dose during controlled ovarian stimulation (COS) when using a GnRH-ant protocol may be beneficial to embryo implantation. However, whether or not the minimum daily GnRH-ant dose should be individualized remains uncertain. In this retrospective study, we aimed to elucidate the feasibility and effectiveness of moderately reducing the daily GnRH-ant dose to 0.125 mg, and then adjusting the dose to 0.25 mg based on subsequent luteinizing hormone (LH) levels. Of the 434 patients analyzed in this study, 209 received our new flexible low-dose GnRH-ant protocol (Group 1) and 225 received a conventional GnRH-ant protocol with a fixed daily dose of 0.25 mg (Group 2). Furthermore, 105 and 114 cycles from groups 1 and 2 received fresh embryo transfer. In Group 1, 30 patients whose dose of 0.125 mg GnRH-ant was adjusted according to their LH levels and 179 patients who received consistently low doses were further divided into subgroups 1 and 2, respectively. Neither the number of retrieved oocytes and available embryos nor the implantation rate, clinical pregnancy rate, and ongoing pregnancy rate significantly differed between the two groups. However, GnRH-ant dose and stimulation duration were much lower and shorter in Group 1 than in Group 2 (p < 0.05). Subgroup 1 exhibited higher basal follicle-stimulating hormone (FSH) and lower antral follicle count (AFC) than subgroup 2 significantly. The number of retrieved oocytes and available embryos were lower in subgroup 1 than in subgroup 2 (6.83 ± 3.28 vs. 11.83 ± 4.82, 2.93 ± 1.86 vs. 4.99 ± 3.46, respectively, p < 0.05), while more canceled cycles for pre-ovulation occurred in subgroup 1 than in subgroup 2 (3/30 vs. 1/179, p < 0.05). The results showed that the flexible low-dose GnRH-ant protocol was as effective as the conventional fixed-dose GnRH-ant protocol with 0.25 mg per day for most patients with normal ovarian reserve. This retrospective analysis and the small sample size are the main limitations of this study, and a large sample RCT will be carried out in the future.

Abstract
Because of the deep involvement of granulosa cells in the processes surrounding the cycles of menstruation and reproduction, there is a great need for a deeper understanding of the ways in which they function during the various stages of those cycles. One of the main ways in which the granulosa cells influence the numerous sex associated processes is hormonal interaction. Expression of steroid sex hormones influences a range of both primary and secondary sexual characteristics, as well as regulate the processes of oogenesis, folliculogenesis, ovulation, and pregnancy. Understanding of the exact molecular mechanisms underlying those processes could not only provide us with deep insight into the regulation of the reproductive cycle, but also create new clinical advantages in detection and treatment of various diseases associated with sex hormone abnormalities. We have used the microarray approach validated by RT-qPCR, to analyze the patterns of gene expression in primary cultures of human granulosa cells at days 1, 7, 15, and 30 of said cultures. We have especially focused on genes belonging to ontology groups associated with steroid biosynthesis and metabolism, namely “Regulation of steroid biosynthesis process” and “Regulation of steroid metabolic process”. Eleven genes have been chosen, as they exhibited major change under a culture condition. Out of those, ten genes, namely STAR, SCAP, POR, SREBF1, GFI1, SEC14L2, STARD4, INSIG1, DHCR7, and IL1B, belong to both groups. Patterns of expression of those genes were analyzed, along with brief description of their functions. That analysis helped us achieve a better understanding of the exact molecular processes underlying steroid biosynthesis and metabolism in human granulosa cells.

Abstract
Current studies have revealed that aging is a negative factor that suppresses granulosa cell functions and causes low fertility in women. However, the difference in gene expression between normal and aging granulosa cells remains undefined. Therefore, the aim of this study was to investigate the gene expression profiles of granulosa cells during aging. Granulosa cells from young healthy porcine ovaries were aged in vitro by prolonging the culture time (for 48h). First, the extracellular ultrastructure was observed by scanning electron microscopy followed by RNA-seq and KEGG pathway analysis. The results showed that the extracellular ultrastructure was significantly altered by aging; cell membranes were rough, and cavitations were found. Moreover, the formations of filopodia were greatly reduced. RNA-seq data revealed that 3411 genes were differentially expressed during aging, of which 2193 genes were up-regulated and 1218 genes were down-regulated. KEGG pathway analysis revealed that 25 pathways including pathway in cancer, PI3K-Akt signaling pathway, focal adhesion, proteoglycans in cancer, and cAMP signaling pathway were the most changed. Moreover, several high differentially expressed genes (CEBPB, CXCL12, ANGPT2, IGFBP3, and BBOX1) were identified in aging granulosa cells, The expressions of these genes and genes associated with extracellular matrix remodeling associated genes (TIMP3, MMP2, MMP3, and CTGF), energy metabolism associated genes (SLC2A1, PPARγ) and steroidogenesis associated genes (StAR, CYP11A1 and LHCGR) were confirmed by quantitative PCR. This study identifies the differently changed pathways and their related genes, contributes to the understanding of aging in granulosa cells, and provides an important foundation for further studies.

Abstract
'Poor responders' is a term used to describe a subpopulation of IVF patients who do not respond well to ovarian stimulation with gonadotrophins. While there is no standard definition of a poor responder, these patients tend to be of advanced maternal age (≥40 years), have a history of poor ovarian response with conventional stimulation protocols, and/or have low ovarian reserve. Despite the heterogeneity of this patient group, there are characteristics and needs common to many poor responders that can be addressed through a holistic approach. Stimulation during the earlier stages of follicle maturation may help synchronize follicle development for improved response to later gonadotrophin stimulation, and supplementation with dehydroepiandrosterone or human growth hormone may promote early follicle development in poor responders. IVF protocols should be specifically tailored to poor responders to complement the patient's natural cycle. Because poor responders tend to have high levels of stress and anxiety, patients should receive psychological counselling and support, both prior to and during IVF cycles, to ensure optimal outcomes and improve patients' experience. It is important to set realistic expectations with poor responders and their partners to help patients make informed decisions and better manage their distress and anxiety.

Abstract
BACKGROUND The use of progestin (P) during ovarian stimulation is effective in blocking the luteinizing hormone (LH) surge in women with normal ovarian reserve, however, its effects have not been determined in poor responders. This study aimed to explore the follicular dynamics in P-primed minimal stimulation in poor responders. METHODS A total of 204 infertile women with diminished ovarian reserve were allocated into the medroxyprogesterone acetate (MPA) group or the natural-cycle control group in an alternating order. MPA (10 mg) was administered daily beginning from the early follicular phase and a low dose of hMG was added in the late follicular phase if the serum FSH level was lower than 8.0mIU/ml. When a dominant follicle reached maturity, triptorelin 100 μg and hCG 1000 IU were used for trigger, and oocytes were retrieved 34-36 h later.All viable embryos were cryopreserved for subsequent frozen embryo transfer. Natural cycle IVF was used as controls. RESULTS Compared with the natural cycle group, the MPA group exhibited a larger pre-ovulatory follicle (18.7 ± 1.8 mm vs 17.2 ± 2.2 mm), a longer follicular phase (13.6 ± 3.6 days vs 12.3 ± 3.2 days), and higher peak oestradiol values (403.88 ± 167.16 vs 265.26 ± 122.16 pg/ml), while maintaining lower LH values (P < 0.05). The incidences of spontaneous LH surge and premature ovulation decreased significantly (1.0% vs 50%; 2% vs. 10.8%, respectively; P < 0.05). A greater number of oocytes and viable embryos were harvested from the MPA group than from the natural cycle group (P < 0.05). Moreover,the clinical pregnancy rate was slightly higher in the MPA group than in the natural cycle controls, but the difference was not significant (11.8% vs 5.9%, P > 0.05). CONCLUSION This study supported the hypothesis that P-primed minimal stimulation achieved ovulation control of the dominant follicle and did not adversely affect the quality of oocytes in poor responders. Therefore, P-priming is a promising approach to overcome premature ovulation in minimal stimulation for poor responders. TRIAL REGISTRATION ChiCTR-OCH-14004176 . Registered on January 8, 2014.

Abstract
Members of the transforming growth factor-beta (TGF-beta) superfamily are key regulators of various physiological processes. Anti-Müllerian hormone (AMH) which is also commonly known as Müllerian-inhibiting substance (MIS) is a member of the TGF-beta superfamily and an important regulator of reproductive organ differentiation and ovarian follicular development. While AMH has been used for diagnostic purposes as a biomarker for over 15 years, new potential therapeutic applications of recombinant human AMH analogues are now emerging as pharmacologic agents in reproductive medicine. Therapeutic uses of AMH in gonadal tissue may provide a unique opportunity to address a broad range of reproductive themes, like contraception, ovulation induction, onset of menopause, and fertility preservation, as well as specific disease conditions, such as polycystic ovarian syndrome (PCOS) and cancers of the reproductive tract. This review explores the most promising therapeutic applications for a novel class of drugs known as AMH analogues with agonist and antagonist functions.

Abstract
The endocrine function of the ovary is dependent upon the ovarian follicle, which on a cellular basis consists of an oocyte surrounded by adjacent somatic cells responsible for generating sex steroid hormones and maintenance of hormonal stasis with the hypothalamic-pituitary axis. As females age, both fertility and the endocrine function of the ovary decline due to waning follicle numbers as well as aging-related cellular dysfunction. Although there is currently no cure for ovarian failure and endocrine disruption, recent advances in ovarian biology centered on ovarian stem cell and progenitor cell populations have brought the prospects of cell- or tissue-based therapeutic strategies closer to fruition. Herein, we review the relative contributions of ovarian stem cells to ovarian function during the reproductive lifespan, and postulate steps toward the development of ovarian stem cell-based approaches to advance fertility treatments, and also importantly to provide a physiological long-term means of endocrine support.

Abstract
How anti-Müllerian hormone (AMH) and testosterone (T) interrelate in infertile women is currently largely unknown. We, therefore, in a retrospective cohort study investigated how infertile women with high-AMH (AMH ≥75th quantile; n=144) and with normal-AMH (25th-75th quantile; n=313), stratified for low-T (total testosterone ≤19.0ng/dL), normal-T (19.0-29.0ng/dL) and high-T (>29.0ng/dL) phenotypically behaved. Patient age, follicle stimulating hormone (FSH), dehyroepiandrosterone (DHEA), DHEA sulphate (DHEAS), cortisol (C), adrenocorticotrophic hormone (ACTH), IVF outcomes, as well as inflammatory and immune panels were then compared between groups, with AMH and T as variables. We identified a previously unknown infertile PCOS-like phenotype, characterized by high-AMH but, atypically, low-T, with predisposition toward autoimmunity. It presents with incompatible high-AMH and low-T (<19.0ng/dL), is restricted to lean PCOS-like patients, presenting delayed for tertiary fertility services. Since also characterized by low DHEAS, low-T is likely of adrenal origina, and consequence of autoimmune adrenal insufficiency since also accompanied by low-C and evidence of autoimmunity. DHEA supplementation in such patients equalizes low- to normal-T and normalizes IVF cycle outcomes. Once recognized, this high-AMH/low-T phenotype is surprisingly common in tertiary fertility centers but, currently, goes unrecognized. Its likely adrenal autoimmune etiology offers interesting new directions for investigations of adrenals control over ovarian function via adrenal androgen production.

Time- and Dose-Dependent Effects of 17 Beta-Estradiol on Short-Term, Real-Time Proliferation and Gene Expression in Porcine Granulosa Cells. BIOMED RESEARCH INTERNATIONAL 2017; 2017:9738640.

Abstract
The key mechanisms responsible for achievement of full reproductive and developmental capability in mammals are the differentiation and transformation of granulosa cells (GCs) during folliculogenesis, oogenesis, and oocyte maturation. Although the role of 17 beta-estradiol (E2) in ovarian activity is widely known, its effect on proliferative capacity, gap junction connection (GJC) formation, and GCs-luteal cells transformation requires further research. Therefore, the goal of this study was to assess the real-time proliferative activity of porcine GCs in vitro in relation to connexin (Cx), luteinizing hormone receptor (LHR), follicle stimulating hormone receptor (FSHR), and aromatase (CYP19A1) expression during short-term (168 h) primary culture. The cultured GCs were exposed to acute (at 96 h of culture) and/or prolonged (between 0 and 168 h of culture) administration of 1.8 and 3.6 μM E2. The relative abundance of Cx36, Cx37, Cx40, Cx43, LHR, FSHR, and CYP19A1 mRNA was measured. We conclude that the proliferation capability of GCs in vitro is substantially associated with expression of Cxs, LHR, FSHR, and CYP19A1. Furthermore, the GC-luteal cell transformation in vitro may be significantly accompanied by the proliferative activity of GCs in pigs.

Abstract
In poor prognosis patients undergoing in vitro fertilization, advance determinations of likely oocyte yields are especially important since oocyte numbers to large degree determine in vitro fertilization cycle outcomes. Based on baseline follicle stimulating hormone and anti-müllerian hormone levels at time of initial presentation, we here, therefore, determined at all ages the probabilities of obtaining 1-≥5 oocytes in a retrospective analysis of 1554 consecutive patients undergoing in vitro fertilization cycles at an academically affiliated private fertility center. At lowest levels (≤2.5 mIU/mL), Follicle stimulating hormone at all ages was highly predictable for ≥1 oocyte (88-96 %). Probabilities declined and diverged between ages with increasing follicle stimulating hormone, though narrowed again at high follicle stimulating hormone. Anti-Müllerian hormone demonstrated at higher levels (2.5-≥5 ng/ml) at all ages almost perfect probabilities (99-100 %). With declining anti-Müllerian hormone, age categories, however, increasingly diverged, though to lesser degree than follicle stimulating hormone. In poor prognosis patients, follicle stimulating hormone and anti-Müllerian hormone, thus, offer at different ages very specific probabilities for retrieval of 1-≥5 oocytes. Since oocyte numbers are associated with embryo numbers, and numbers of transferable embryos with live birth rates, here presented probability tables should facilitate improved prognostication of poor prognosis patients. Discrepancies in here reported probabilities between follicle stimulating hormone and anti-müllerian hormone also further define follicle stimulating hormone and anti-müllerian hormone in their respective abilities to represent functional ovarian reserve at different ages.

Abstract
With granulosa and theca cells, the ovaries are responsible for producing oocytes and secreting sex steroids such as estrogen and progesterone. Endoplasmic reticulum stress (ERS) plays an important role in follicle atresia and embryo implantation. In this study, goat granulosa cells were isolated from medium-sized (4-6 mm) healthy follicles. Primary granulosa cells were immortalized by transfection with human telomerase reverse transcriptase (hTERT) to establish a goat granulosa cell line (hTERT-GGCs). These hTERT-GGCs expressed hTERT and had relatively long telomeres at passage 50. Furthermore, hTERT-GGCs expressed the gonadotropin receptor genes CYP11A1, StAR, and CYP19A1, which are involved in steroidogenesis. Additionally, progesterone was detectable in hTERT-GGCs. Although the proliferation potential of hTERT-GGCs significantly improved, there was no evidence to suggest that the hTERT-GGCs are tumorigenic. In addition, thapsigargin (Tg) treatment led to a significant dose-dependent decrease in progesterone concentration and steroidogenic enzyme expression. In summary, we successfully generated a stable goat granulosa cell line. We found that Tg induced ERS in hTERT-GGCs, which reduced progesterone production and steroidogenic enzyme expression. Future studies may benefit from using this cell line as a model to explore the molecular mechanisms regulating steroidogenesis and apoptosis in goat granulosa cells.

Abstract
Women above age 40 years in the US now represent the most rapidly growing age group having children. Patients undergoing in vitro fertilization (IVF) are rapidly aging in parallel. Especially where egg donations are legal, donation cycles, therefore, multiply more rapidly than autologous IVF cycles. The donor oocytes, however, are hardly ever a preferred patient choice. Since with use of own eggs, live birth rates decline with advancing age but remain stable (and higher) with donor eggs, older patients always face the difficult and very personal choice between poorer chances with own and better chances with donor oocytes. Physician contribution to this decision should in our opinion be restricted to accurate outcome information for both options. Achievable pregnancy and live birth rates in older women are, however, frequently underestimated, thereby mistakenly biasing fertility providers, private insurance companies and even regulatory government agencies. Restriction on access to IVF for older women is then often the consequence. In this review, we summarize the limited published data on best treatments of 'older' ovaries, while also addressing treatment approaches that should be avoided in older women. This focused review, therefore, to a degree is subjective. Research addressing aging ovaries in IVF has been disappointingly sparse, and has in our opinion too heavily concentrated on methods of embryo selection (ES), which, especially in older women, not only fail to improve IVF outcomes, but actually, negatively affect live birth chances. We conclude that, aside from breakthroughs in gamete creation, only pharmacological interventions into early (small growing follicle stages) follicle maturation will offer new potential to positively impact oocyte and embryo quality and, therefore, IVF outcomes. Research, therefore, should be accordingly redirected.

Definition by FSH, AMH and embryo numbers of good-, intermediate- and poor-prognosis patients suggests previously unknown IVF outcome-determining factor associated with AMH. J Transl Med 2016; 14:172. [PMID: 27286817 PMCID: PMC4901433 DOI: 10.1186/s12967-016-0924-7] [Citation(s) in RCA: 29] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2016] [Accepted: 05/30/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Though outcome models have been proposed previously, it is unknown whether cutoffs in clinical pregnancy and live birth rates at all ages are able to classify in vitro fertilization (IVF) patients into good-, intermediate- and poor prognosis. METHODS We here in 3 infertile patient cohorts, involving 1247, 1514 and 632 women, built logistic regression models based on 3 functional ovarian reserve (FOR) parameters, including (1) number of good quality embryos, (2) follicle stimulating hormone (FSH, mIU/mL) and (3) anti-Müllerian hormone (AMH, ng/mL), determining whether clinical pregnancy and live birth rates can discriminate between good, intermediate and poor prognosis patients. RESULTS All models, indeed, allowed at all ages for separation by prognosis, though cut offs changed with age. In the embryo model, increasing embryo production resulted in linear improvement of IVF outcomes despite transfer of similar embryo numbers; in the FSH model outcomes and FSH levels related inversely, while the association of AMH followed a bell-shaped polynomial pattern, demonstrating "best" outcomes at mid-ranges. All 3 models demonstrated increasingly poor outcomes with advancing ages, though "best" AMH even above age 43 was still associated with unexpectedly good pregnancy and delivery outcomes. Excessively high AMH, in contrast, was at all ages associated with spiking miscarriage rates. CONCLUSIONS At varying peripheral serum concentrations, AMH, thus, demonstrates hithero unknown and contradictory effects on IVF outcomes, deserving at different concentrations investigation as a potential therapeutic agent, with pregnancy-supporting and pregnancy-interrupting properties.

Abstract
STUDY QUESTION Can RNA sequencing of human cumulus cells (CC) reveal molecular pathways involved in the physiology of reproductive aging? STUDY FINDING Senescent but not young CC activate gene pathways associated with hypoxia and oxidative stress. WHAT IS KNOWN ALREADY Shifts in socioeconomic norms are resulting in larger numbers of women postponing childbearing. The reproductive potential is sharply decreased with aging, and the reasons are poorly understood. Since CCs play an integral role in oocyte maturation and direct access to human oocytes is limited, we used whole transcriptome analysis of these somatic cells to gain insights into the molecular mechanisms playing a role in follicular senescence. STUDY DESIGN, SAMPLES/MATERIALS, METHODS Twenty CC samples (from a total of 15 patients) were obtained from oocytes of either male factor or egg donor patients. RNA sequencing and bioinformatic tools were used to identify differentially expressed genes between CCs from seven aged and eight young patients (<35 (years old) y.o. vs >40 y.o.). Quantitative-PCR and immunoflourescent staining were used for validation. MAIN RESULTS AND THE ROLE OF CHANCE RNA sequencing identified 11 572 genes expressed in CC of both age cohorts, 45 of which were differentially expressed. In CC collected from patients >40 y.o., genes involved in the hypoxia stress response (NOS2, RORA and NR4A3), vasculature development (NR2F2, PTHLH), glycolysis (RALGAPA2 and TBC1D4) and cAMP turnover (PDE4D) were significantly overexpressed when compared with CC of patients younger than 35 y.o. LIMITATIONS, REASONS FOR CAUTION This study focused almost exclusively on assessing the genetic differences in CC transcriptome between young and older women. These genetic findings were not fully correlated with embryonic development and clinical outcome. WIDER IMPLICATIONS OF THE FINDINGS Our data provide a new hypothesis-follicular hypoxia-as the main mechanism leading to ovarian follicular senescence and suggest a link between cumulus cell aging and oocyte quality decay. If specific molecular findings of hypoxia would be confirmed also in oocytes, genetic platforms could screen CC for hypoxic damage and identify healthier oocytes. Protocols of ovarian stimulation in older patients could also be adjusted to diminish oocyte exposure time to hypoxic follicles.
