Abstract
PURPOSE To compare the effects of the gonadotrophin-releasing hormone (GnRH) agonist protocol, GnRH antagonist protocol, progestin-primed ovarian stimulation (PPOS) protocol, and mild stimulation/natural cycle protocol on the cumulative live birth rate (CLBR) in patients with adenomyosis and Poseidon group 3/4. METHODS A total of 1090 patients diagnosed with adenomyosis and Poseidon groups 3/4 group who underwent in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) from January 2013 to December 2020 were included. Demographic characteristics, laboratory indicators, and clinical outcomes of the four ovarian stimulation protocols were compared. The primary outcome was the CLBR, with binary logistic regression analysis used to explore the factors influencing CLBR. RESULTS Among the patients with adenomyosis and Poseidon groups 3/4, the CLBR in GnRH agonist protocol group was higher than that in PPOS protocol group (45.78% vs. 22.33%, P = 0.005). Binary logistic regression analysis revealed that GnRH agonist protocol had a higher CLBR compared to PPOS protocol (adjusted odds ratio (aOR) 3.26, 95% confidence interval (CI): 1.56-6.83, P = 0.002), while no significant differences were found when comparing PPOS protocol with GnRH antagonist protocol (P = 0.093) and mild stimulation/natural cycle protocol (P = 0.125). In the < 35 years subgroup, the CLBR of GnRH agonist protocol was significantly higher (55.26% vs. 33.82%; P = 0.032), which wasn't observed in elder subgroups (P > 0.05). CONCLUSION For patients with both adenomyosis and Poseidon groups 3/4, GnRH agonist protocol showed a higher CLBR, especially in patients < 35 years (Poseidon group 3).

Comparison of Assisted Reproductive Technology (ART) Outcomes in Two Controlled Ovarian Stimulation Protocols Using Follitropin Delta, a Recombinant Follicle-Stimulating Hormone (rFSH) Injection. Cureus 2025; 17:e81281. [PMID: 40291328 PMCID: PMC12032857 DOI: 10.7759/cureus.81281] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/26/2025] [Indexed: 04/30/2025] Open
Abstract
AIM This study aimed to compare the outcomes of assisted reproductive technology (ART) between progestin-primed ovarian stimulation (PPOS) and antagonist protocols, using follitropin delta as the sole ovarian stimulation agent. While many comparative studies on PPOS and antagonist protocols exist, most utilize follitropin alpha or beta as stimulatory agents. Notably, no studies have reported on the use of follitropin delta in this context. METHODOLOGY A retrospective analysis was conducted on ART cases initiated in 2022, including 529 PPOS cycles and 298 antagonist cycles. Subgroup analyses were performed based on anti-Müllerian hormone (AMH) levels, dividing patients into four groups: <1.2 ng/mL, 1.2≤ AMH <2.03 ng/mL, 2.03≤ AMH <5.0 ng/mL, and ≥5.0 ng/mL. Assessed outcomes included the number of retrieved oocytes, fertilization rates, cleavage rates, blastocyst formation rates (BL rates), and good-quality blastocyst formation rates (GBL rates), as well as the number of retrieved oocytes, fertilized embryos, cleavage-stage embryos, BL, and GBL. All cases were planned for complete blastocyst vitrification, including those in the antagonist group. RESULTS The mean patient age was 35.1 years in the PPOS group and 36.2 years in the antagonist group. Other baseline characteristics included the causes and duration of infertility, proportion of primary infertility, baseline hormone levels, BMI, duration and dosage of follitropin delta administration, and duration of medroxyprogesterone acetate (MPA) use. There were no significant differences in the background characteristics between the two groups. In AMH levels of 2.03 ng/mL and above, the two groups with AMH-based subgroups showed that the PPOS protocol demonstrated a significantly higher number of retrieved oocytes, BL, and GBL compared to the antagonist protocol. CONCLUSION While previous studies have indicated that no significant differences in outcomes between these protocols, the present study observed that the follitropin delta enhanced the formation of blastocysts and good-quality blastocysts. Further research is needed to determine whether these findings are specific to follitropin delta or extend to other recombinant follicle-stimulating hormone (rFSH) preparations.

Abstract
CONTEXT Progestins have recently been used as an alternative for gonadotropin-releasing hormone (GnRH) analogues to prevent premature luteinizing hormone surge due to the application of vitrification technology. However, the long-term efficacy and safety of a progestin-primed ovarian stimulation (PPOS) regimen, including oocyte competence, cumulative live birth rate (LBR), and offspring outcomes, remain to be investigated. OBJECTIVE To compare cumulative LBR of preimplantation genetic testing (PGT) cycles between a PPOS regimen and GnRH analogues. METHODS This was a retrospective cohort study at a tertiary academic medical center. A total of 967 patients with good prognosis were categorized into 3 groups: 478 patients received a long GnRH agonist, 248 patients received a GnRH antagonist, and 250 received a PPOS regimen. Medroxyprogesterone 17-acetate was the only progestin used in the PPOS regimen. The primary outcome was cumulative LBR. Secondary outcomes included time to live birth, cumulative rates of biochemical and clinical pregnancy and pregnancy loss, and perinatal outcomes. RESULTS The PPOS regimen was negatively associated with cumulative LBR compared with GnRH antagonists and GnRH agonists (28.4% vs 40.7% and 42.7%). The average time to live birth was significantly shorter with GnRH antagonists than with the PPOS regimen. The cumulative biochemical and clinical pregnancy rates were also lower in the PPOS regimen than GnRH analogues, while cumulative pregnancy loss rates were similar across groups. Furthermore, the number and ratio of good-quality blastocysts were significantly reduced in the PPOS regimen compared with GnRH analogues. In addition, perinatal outcomes were comparable across 3 groups. CONCLUSION A PPOS regimen may adversely affect cumulative LBR and blastocyst quality in women with good prognosis compared with GnRH analogues in PGT cycles.

Flexible progestin-primed ovarian stimulation versus a GnRH antagonist protocol in predicted suboptimal responders undergoing freeze-all cycles: a randomized non-inferiority trial. Hum Reprod 2025; 40:319-327. [PMID: 39729571 DOI: 10.1093/humrep/deae286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2024] [Revised: 11/28/2024] [Indexed: 12/29/2024] Open
Abstract
STUDY QUESTION Are live birth rates (LBRs) per woman following flexible progestin-primed ovarian stimulation (fPPOS) treatment non-inferior to LBRs per woman following the conventional GnRH-antagonist protocol in expected suboptimal responders undergoing freeze-all cycles in assisted reproduction treatment? SUMMARY ANSWER In women expected to have a suboptimal response, the 12-month likelihood of live birth with the fPPOS treatment did not achieve the non-inferiority criteria when compared to the standard GnRH antagonist protocol for IVF/ICSI treatment with a freeze-all strategy. WHAT IS KNOWN ALREADY The standard PPOS protocol is effective for ovarian stimulation, where medroxyprogesterone acetate (MPA) is conventionally administered in the early follicular phase for ovulatory suppression. Recent retrospective cohort studies on donor cycles have shown the potential to prevent premature ovulation and maintain oocyte yields by delaying the administration of MPA until the midcycle (referred to as fPPOS), similar to GnRH antagonist injections. With milder pituitary suppression, the fPPOS protocol may be a less costly option for women expected to have a low or suboptimal response if a fresh embryo transfer is not intended. STUDY DESIGN, SIZE, DURATION This was a non-inferiority, open-label randomized controlled trial conducted at a tertiary assisted reproduction center. A total of 484 participants were randomized in the study between July 2020 and June 2023 with a 1:1 allocation. PARTICIPANTS/MATERIALS, SETTING, METHODS Infertile women with a predicted suboptimal ovarian response (<40 years old, antral follicle count <10, and basal serum FSH < 12 mIU/ml) were randomly assigned to receive either fPPOS treatment or GnRH antagonist treatment. MPA (10 mg) or GnRH antagonist (0.25 mg) was administered daily once the leading follicle reached 14 mm and continued until the day of trigger. All viable embryos were cryopreserved for subsequent frozen-thawed embryo transfer in both groups. The primary endpoint was the proportion of live births per woman within 12 months post-randomization (with a non-inferiority margin of -12.5%). The analysis was assessed in the per-protocol population. MAIN RESULTS AND THE ROLE OF CHANCE Twenty-two women withdrew at the beginning of the stimulation phase due to COVID-19. Eight women did not proceed with the assigned frozen embryo transfer, and six switched from the fPPOS to the antagonist protocol. Overall, 449 women were included in the per-protocol analysis, with 216 in the fPPOS group and 233 in the GnRH antagonist group. The LBRs per woman were 44.4% (96/216) for participants in the fPPOS group and 48.9% (114/233) for participants in the GnRH antagonist group [risk ratio (RR) 0.91 (95% CI, 0.74, 1.11), risk difference (RD) -4.5% (95% CI, -13.7, 4.7)], which did not meet the non-inferiority criterion (-12.5%). Oocyte and embryonic parameters were not significantly different between the two groups. Nine women (4.17%) in the fPPOS group experienced a premature luteinizing hormone surge, compared to five women (2.15%) in the antagonist group. Only one woman in the fPPOS group ovulated before oocyte retrieval. LIMITATIONS, REASONS FOR CAUTION The distinct routes of administration for the medications precluded blinding in this open-label trial, potentially influencing outcome assessments. All participants were recruited in a single center from one country, limiting the generalizability. WIDER IMPLICATIONS OF THE FINDINGS While MPA is considered a patient-friendly alternative to antagonists for women undergoing scheduled freeze-all cycles, the GnRH antagonist protocol should still be the preferred treatment for anticipated suboptimal responders in terms of LBR.

Abstract
OBJECTIVE To investigate the chromosome abnormality rates and clinical pregnancy outcomes after preimplantation genetic testing for aneuploidy (PGT-A) using either the progestin-primed ovarian stimulation (PPOS) protocol or the gonadotropin-releasing hormone (GnRH) antagonist protocol. METHODS The study included 431 PGT-A cycles in which controlled ovarian stimulation was performed using the PPOS protocol (n = 320 cycles) or GnRH antagonist protocol (n = 111 cycles) between January 2018 and December 2021. Frozen embryo transfer was subsequently performed in 307 cycles with transferable blastocysts. The number of retrieved oocytes, embryo development, next-generation sequencing results, and clinical pregnancy outcomes were compared between the two protocols. The primary outcome measure was the aneuploidy rate. Secondary outcome measures were clinical pregnancy per first frozen-thawed embryo transfer cycle and cumulative live birth rates per PGT-A cycle. RESULTS There were no statistically significant between-group differences in the number of retrieved oocytes, available blastocysts, and high-quality blastocyst rate. The aneuploidy rates were similar between the two groups. There was no significant difference in clinical pregnancy outcomes, including the clinical pregnancy, implantation, miscarriage, live birth, or cumulative live birth rates, after frozen-thawed embryo transfer cycles (P>0.05). CONCLUSIONS The study found no significant differences in the aneuploidy rate, clinical pregnancy rate and cumulative live birth rate after PGT-A cycles between those using the PPOS protocol and those using the GnRH antagonist protocol.

Abstract
The judicious selection of ovulation inhibitors in ovarian stimulation protocols is crucial for the success of assisted reproductive technology (ART). Herein, we investigate the dose-dependent effects of chlormadinone acetate (CMA) and cetrorelix, two distinct ovulation inhibitors, on oocyte maturation in patients with normal ovarian reserve, using univariable and multivariable Poisson regression analyses. Patients undergoing progestin-primed ovarian stimulation (PPOS) with CMA (n = 299) or gonadotropin-releasing hormone antagonist (GnRH-ant) with cetrorelix (n = 605) during their initial in vitro fertilization cycle were enrolled at our center from March 2018 to October 2020 (N = 904). The primary and secondary outcomes were the oocyte maturation and fertilization rates, respectively. After adjusting for several covariates including age, anti-Müllerian hormone levels, total gonadotropin dose, and type of trigger, we calculated the dose-dependent adjusted relative risk (aRR) and 95% confidence interval (CI) for 1 mg of CMA or 0.25 mg of cetrorelix. In the PPOS group, the median age was 34.0 years, and the median total CMA dosage was 22 mg (interquartile range [IQR]: 18.0-32.0). In the GnRH-ant group, the median age was 35.0 years, and the median total cetrorelix dosage was 0.5 mg (IQR 0.5-0.5). The aRR of the maturation rate was 1.003 (95% CI: 0.999-1.007) with PPOS (p = 0.194) and 1.009 (95% CI: 0.962-1.059) with GnRH-ant (p = 0.717). The aRR of the fertilization rate was 1.002 (95% CI: 0.985-1.020) with PPOS (p = 0.783) and 1.022 (95% CI: 0.839-1.246) with GnRH-ant (p = 0.829). Collectively, these findings indicate that within the applied dosages, ovulation inhibitors do not significantly impact oocyte maturation or fertilization rates in patients with normal ovarian reserve. These valuable insights can be applied when designing ART protocols and may guide clinicians in optimizing infertility treatments.

Abstract
This study aimed to evaluate the cumulative live birth rate (cLBR) of progestin-primed ovarian stimulation (PPOS) protocol versus gonadotropin-releasing hormone antagonist (GnRH-ant) protocol for in vitro fertilization (IVF) cycle in infertile women with normal ovarian reserve (NOR). Infertile women with NOR who underwent their first IVF cycle were enrolled in an open-label randomized controlled trial. Patients were randomly assigned 1:1 to receive a freeze-all strategy with delayed embryo transfer (PPOS group, n = 174) and fresh embryo transfer first (GnRH-ant group, n = 174). The primary outcome was the cLBR per aspiration. The cLBR between the PPOS group and GnRH-ant group were comparable (55.75% vs. 52.87%, p = 0.591). A premature luteinizing hormone surge was not observed in the PPOS group, while there were six cases (3.45%) in the GnRH-ant group, but no premature ovulation in either of the groups. The pregnancy outcomes, including implantation rate, clinical pregnancy rate and miscarriage rate, were all comparable. In addition, the number of retrieved oocytes, mature oocytes and viable embryos were similar (all p > 0.05) between the two groups.

Zeng Y, Liu Y, Nie Y, Shen X, Wang T, Kuang Y, Wang L. Women may not benefit from repeated frozen embryo transfers: a retrospective analysis of the cumulative live birth rate of 43 972 women. Hum Reprod Open 2024; 2024:hoae063. [PMID: 39539356 PMCID: PMC11557905 DOI: 10.1093/hropen/hoae063] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2024] [Revised: 09/24/2024] [Indexed: 11/16/2024] Open
Abstract
STUDY QUESTION Which specific groups of women would not benefit from repeated frozen embryo transfers (FETs)? SUMMARY ANSWER Women over 45 years of age should stop treatment after three FET attempts due to the absence of further benefits, while women aged 40-45 years and those with a diminished ovarian reserve and other causes of infertility have a lower chance of improving their cumulative live birth rate (CLBR) within five FET cycles and experience fewer advantages from repeated transfers. WHAT IS KNOWN ALREADY In real-life scenarios of ART, women who fail to achieve a live birth often choose to undergo repeated FETs via the freeze-all strategy. STUDY DESIGN SIZE DURATION This retrospective study included 43 972 women who underwent 86 496 oocyte retrieval cycles and 82 022 FET cycles between January 2010 and March 2023 under the freeze-all strategy. PARTICIPANTS/MATERIALS SETTING METHODS We categorized the population based on the female's age at the first oocyte pick-up (OPU) cycle (Groups 1-6: <30, 30-34, 35-39, 40-42, 43-44, and ≥45 years of age), number of retrieved oocytes at the first OPU cycle (Groups 1-5: 1-5, 6-10, 11-15, 16-20, and >20 oocytes), and causes of infertility (Groups 1-9: tubal factor, male factor, polycystic ovary syndrome, diminished ovarian reserve, endometriosis, other uterine factors, combined factors, unexplained infertility, and other infertility) to analyse their CLBRs within different FET cycles via Kaplan-Meier analysis (optimistic method) and the competing risk method (conservative method). We utilized multivariate Cox and Fine-Gray models to examine the associations between the CLBR and age, the number of retrieved oocytes, and nine causes of infertility. MAIN RESULTS AND THE ROLE OF CHANCE The CLBR decreased with increasing female age over five FET cycles (Groups 1-6: optimistic method: 96.4%, 94.2%, 86.0%, 50.2%, 23.1%, and 10.1%; conservative method: 87.1%, 82.0%, 67.8%, 33.9%, 13.8%, and 3.5%, respectively). Moreover, there was an increasing trend in the number of retrieved oocytes (Groups 1-5: optimistic method: 82.5%, 91.7%, 93.6%, 94.1%, and 96.2%; conservative method: 58.6%, 76.7%, 84.8%, 88.0%, and 92.5%, respectively). Furthermore, the CLBR varied across different causes of infertility (Groups 1-9: optimistic method: 91.7%, 93.1%, 96.6%, 79.2%, 89.9%, 76.1%, 90.0%, 92.9%, and 35.4%; conservative method: 77.3%, 79.4%, 88.9%, 46.7%, 72.7%, 62.1%, 74.4%, 78.8%, and 20.1%, respectively). LIMITATIONS REASONS FOR CAUTION Calculating the actual CLBR for each person is difficult because some patients have remaining embryos that have not been transferred; additionally, the current statistical methodology uses both optimistic and conservative methods to calculate the CLBR, and in real life, the CLBR falls between the optimistic and conservative curves. WIDER IMPLICATIONS OF THE FINDINGS Our study is the first to identify specific subgroups of women who fail to benefit from repeated FETs and who require rational discontinuation of treatment following unsuccessful transfer. STUDY FUNDING/COMPETING INTERESTS This study was financially supported by grants from the National Natural Science Foundation of China (grant numbers: 82271732 to Y.K., 82071603 to L.W., 82001502 to Y.L., and 82201888 to X.S.).

Fertil Steril 2024; 121:937-945. [PMID: 38272383 DOI: 10.1016/j.fertnstert.2024.01.027] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2023] [Revised: 01/17/2024] [Accepted: 01/17/2024] [Indexed: 01/27/2024]
Abstract
OBJECTIVE To compare the live birth rate of the first frozen embryo transfer (FET) after ovarian stimulation by the progestin-primed ovarian stimulation (PPOS) protocol vs. the antagonist protocol in women with an anticipated high ovarian response who were undergoing in vitro fertilization. DESIGN Randomized controlled trial. SETTING A tertiary assisted reproduction center. PATIENTS Women with infertility aged <43 years undergoing the first in vitro fertilization cycle and having antral follicle count of >15. INTERVENTIONS Medroxyprogesterone 10 mg daily was given from the start of ovarian stimulation until the day of ovulation trigger in the PPOS protocol. In the antagonist protocol, an antagonist 0.25 mg daily was given from the sixth day of ovarian stimulation until the day of ovulation trigger. Blinding was not possible for women or physicians but the biostatistician was blinded to the group assignment. MAIN OUTCOME MEASURE Live birth rate of the first FET cycle. RESULTS A total of 784 women were recruited from June 2020 and October 2021 and assigned randomly in a 1:1 ratio into two groups: PPOS group (n = 392) and antagonist group (n = 392). Embryo transfer was either cancelled or postponed in 62 women (62/392, 15.8%) in the PPOS group and 65 (65/392, 16.6%) in the antagonist group because of no transferable embryos or no FET within 6 months after randomization. The two groups were similar in demographic characteristics and the numbers of oocytes obtained or fertilized, cleaving embryos, good-quality embryos at day 3, blastocysts developed, and embryos or blastocysts frozen. There was no statistically significant difference in the live birth rate of the first FET cycle between the PPOS and antagonist groups on the basis of both the intention-to-treat analysis (37.5.0% [147/392] vs. 32.7% [128/392]; relative risk, 1.148 [95% confidence interval, 0.949-1.390]) and per-protocol analysis (44.5% [147/330] vs. 39.1% [128/327]; relative risk, 1.138 [95% confidence interval, 0.950-1.364]). Both groups showed comparable clinical pregnancy, ongoing pregnancy, miscarriage, multiple pregnancy, ectopic pregnancy, and cumulative live birth rates. CONCLUSION The live birth rates of the first FET following the PPOS and antagonist protocols were comparable in women with an anticipated high ovarian response. CLINICAL TRIAL REGISTRATION NUMBER NCT04414761 (ClinicalTrials.gov).

Abstract
PURPOSE To evaluate the effectiveness of the progestin-primed ovarian stimulation (PPOS) protocol versus the gonadotropin-releasing hormone antagonist (GnRH-ant) protocol in ovarian stimulation. METHODS In this retrospective cohort study, we included 804 patients who were treated between January 1st, 2022, and July 1st, 2023. Outcomes of ovarian stimulation were compared between the PPOS (n = 206) and GnRH-ant (n = 598). The primary outcome was the number of good cleavage embryos. RESULTS Baseline characteristics were comparable in both groups. In both unadjusted and adjusted analysis, the mean number of good cleavage embryos in PPOS (6.33) was non-inferior to GnRH-ant (6.44; unadjusted ratio of two means 1.02, 95%CI 0.92, 1.13). The trigger-day estradiol level in patients with PPOS was higher than in patients with GnRH-ant (4,420 vs 3,830 pg/ml, respectively) despite similar total follicle stimulating hormone dose and fewer days of ovarian stimulation. The number of oocytes, MII oocytes, cleavage and blastocyst embryos were comparable between the two protocols. After the first transfer of embryos, the clinical pregnancy rate and implantation rate were higher in the PPOS group, while the pregnancy rate and ongoing pregnancy were not significantly different. None of the PPOS patients had an unexpected LH surge, and serum LH levels decreased slightly during ovarian stimulation. CONCLUSIONS The PPOS protocol with dydrogesterone provided similar embryo outcomes to the GnRH-ant protocol, with notable distinctions in clinical pregnancy and implantation rate. The serum LH concentration during ovarian stimulation using PPOS was well-controlled.

Abstract
OBJECTIVES Assessing dienogest's efficacy in endometriosis patients undergoing in vitro fertilization (IVF). DATA SOURCES Systematic search in databases (PubMed, MEDLINE, Embase, Web of Science, Cochrane CENTRAL, Google Scholar) until 1 October 2022. STUDY SELECTIONS Randomized trials and observational studies comparing extended dienogest pre-treatment, no pre-treatment, or gonadotropin-releasing hormone (GnRH) agonist pre-treatment in endometriosis-linked IVF. OUTCOME MEASURES live birth, clinical pregnancy rates, oocytes collected, miscarriage rate, gonadotropin consumption. DATA EXTRACTIONS AND SYNTHESES Two authors independently assessed eligibility. Dichotomous variables were analyzed via a random-effect model and Mantel-Haenszel method to calculate weighted estimates and 95% confidence intervals (CI). I2 statistic gauged study heterogeneity; GRADE criteria evaluated evidence quality. CONCLUSIONS Out of 191 publications, five studies with 723 participants were included. Uncertainty persists on whether prolonged dienogest affects live birth (RR 1.42, 95% CI 0.29 to 6.84; 3 studies, n = 289; I2 86%) and clinical pregnancy rates (RR 1.33, 95% CI 0.31 to 5.65; 3 studies, n = 289; I2 86%) compared to conventional IVF. Moreover, uncertainty remains regarding intervention impact on live birth (RR 1.46, 95% CI 0.63 to 3.37; 1 study, n = 34) and clinical pregnancy rates (RR 1.32, 95% CI 0.78 to 2.23; 3 studies, n = 288; I2 0%) versus long-term GnRH agonist therapy before IVF. Given limited data and very low evidence quality, doubts arise about the benefits of long-term dienogest pre-treatment before conventional IVF in endometriosis patients.

Abstract
PURPOSE Poor ovarian response (POR) is a big challenge for in vitro fertilization. The traditional Chinese medicine, Cai's Prescription of Tonifying Kidney and Strengthening Vitals (Cai's Prescription) has yielded satisfactory results for POR treatment clinically, but systematic scientific research of Cai's Prescription is not well reported. This study aimed to investigate the clinical effect of Cai's Prescription on poor ovarian responders and its biological mechanism. METHODS Serum was collected from poor ovarian responders, and IL-1β, INFγ, FSH, E2 and AMH levels were analyzed by ELISA. Ovarian antral follicles were identified and counted using transvaginal ultrasound. The embryo quality grading were done on day 3 after retrieval. We used high-throughput sequencing of granulosa cells to investigate the gene transcription patterns of ovarian granulosa cells in poor ovarian responders after Cai's Prescription pretreatment. The expression level of ARHGAP4 was analyzed by quantitative real-time PCR and western blot. The effects of ARHGAP4 for granulosa cells were analyzed by CCK-8 assay, annexin-V and PI staining, ELISA and western blot. The effects of Cai's Prescription on the expression of PI3K-Akt pathway and apoptosis were analyzed by western blot. RESULTS In this study, we found that Cai's Prescription pretreatment had the tendency to improve the ovarian reserve function and could increase the number of high quality embryos for poor ovarian responders. Through high-throughput sequencing of mRNA in granulosa cells, we discovered ARHGAP4, which is a member of GTPase-activating proteins (GAPs) may be a candidate target for POR treatment. ARHGAP4 was significantly increased in poor ovarian responders and can be recovered after Cai's Prescription pretreatment. Mechanically, combining the cell line model and clinical tissue samples, we found that ARHGAP4 can accelerate cell apoptosis and inflammation response in granulosa cells via PI3K-Akt signaling pathway. In addition, Cai's Prescription pretreatment for three months significantly reduced the high level of ARHGAP4 in poor ovarian responders. CONCLUSION This study shows that the traditional Chinese medicine, Cai's Prescription yielded satisfactory results for poor ovarian responders clinically and ARHGAP4 may be a candidate target for POR treatment.

Abstract
Progestin-primed ovarian stimulation (PPOS) is being increasingly used for ovarian stimulation in assisted reproductive technology. Different progestins have been used with similar success. The available studies suggest a similar response to ovarian stimulation with gonadotrophin-releasing hormone (GnRH) analogues. Any differences in the duration of stimulation or gonadotrophin consumption are minor and clinically insignificant. PPOS has the advantage of oral administration and lower medication costs than GnRH analogues. As such it is clearly more cost-effective for fertility preservation and planned freeze-all cycles, but when fresh embryo transfer is intended PPOS can be less cost-effective depending on the local direct and indirect costs of the additional initial frozen embryo transfer cycle. Oocytes collected in PPOS cycles have similar developmental potential, including blastocyst euploidy rates. Frozen embryo transfer outcomes of PPOS and GnRH analogue cycles seem to be similar in terms of both ongoing pregnancy/live birth rates and obstetric and perinatal outcomes. While some studies have reported lower cumulative live birth rates with PPOS, they have methodological issues, including arbitrary definitions of the cumulative live birth rate. PPOS has been used in all patient types (except progesterone receptor-positive breast cancer patients) with consistent results and seems a patient friendly and cost-effective choice if a fresh embryo transfer is not intended.

Abstract
Purpose To validate the effectiveness of a gonadotropin starting dose calculator for progestin-primed ovarian stimulation (PPOS), we conducted a study comparing the outcomes of oocyte retrieval between a group assigned gonadotropin doses via the calculator and a control group, where doses were determined by the clinician's empirical judgment. Methods Patients underwent controlled ovarian stimulation (COS) using the PPOS method, followed by oocyte retrieval. We assessed and compared the results of COS and oocyte retrieval in both groups. Additionally, we examined the concordance rate between the number of oocytes actually retrieved and the target number of oocytes in each group. Results The calculated group demonstrated a significantly higher number of preovulation follicles and a higher ovarian sensitivity index than the control group. Furthermore, the discrepancy between the target and actual number of oocytes retrieved was notably smaller in the calculated group. The concordance rate between the target and actual number of oocytes was significantly greater in the calculated group. Conclusions The gonadotropin starting dose calculator proved to be effective within the PPOS protocol, offering a reliable method for predicting the approximate number of oocytes to be retrieved, irrespective of the COS protocol employed.

Abstract
CONTEXT Progestins have recently been used as an alternative for gonadotropin-releasing hormone (GnRH) analogues to prevent premature luteinizing hormone surge due to the application of vitrification technology. However, the long-term efficacy and safety of a progestin-primed ovarian stimulation (PPOS) regimen, including oocyte competence, cumulative live birth rate (LBR), and offspring outcomes, remain to be investigated. OBJECTIVE To compare cumulative LBR of preimplantation genetic testing (PGT) cycles between a PPOS regimen and GnRH analogues. METHODS This was a retrospective cohort study at a tertiary academic medical center. A total of 967 patients with good prognosis were categorized into 3 groups, of which 478 patients received a long GnRH agonist, 248 patients received a GnRH antagonist, and 250 received a PPOS regimen. Medroxyprogesterone 17-acetate was the only progestin used in the PPOS regimen. The primary outcome was cumulative LBR. Secondary outcomes included time to live birth, cumulative rates of biochemical and clinical pregnancy and pregnancy loss, and perinatal outcomes. RESULTS The PPOS regimen was negatively associated with cumulative LBR compared with GnRH antagonists and GnRH agonists (28.4% vs 40.7% and 42.7%). The average time to live birth was significantly shorter with GnRH antagonists than with the PPOS regimen. The cumulative biochemical and clinical pregnancy rates were also lower in the PPOS regimen than GnRH analogues, while cumulative pregnancy loss rates were similar across groups. Furthermore, the number and ratio of good-quality blastocysts were significantly reduced in the PPOS regimen compared with GnRH analogues. In addition, perinatal outcomes were comparable across 3 groups. CONCLUSION A PPOS regimen may be adversely affect cumulative LBR and blastocyst quality in women with good prognosis compared with GnRH analogues in PGT cycles.

The cumulative live birth rates of 18 593 women with progestin-primed ovarian stimulation-related protocols and frozen-thawed transfer cycles. Hum Reprod Open 2023; 2024:hoad051. [PMID: 38188854 PMCID: PMC10769816 DOI: 10.1093/hropen/hoad051] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 11/20/2023] [Indexed: 01/09/2024] Open
Abstract
STUDY QUESTION What are the odds of achieving pregnancy when adopting progestin-primed ovarian stimulation (PPOS)-related protocols combined with repetitive frozen-thawed transfer (FET) cycles in patients with different clinical characteristics? SUMMARY ANSWER The cumulative live birth rates (CLBRs) of women undergoing different PPOS-related protocols can be significantly and consistently enhanced within six FET cycles when the female age is <40 years (or even <45 years) and when >5 oocytes are retrieved, regardless of antral follicle count (AFC). WHAT IS KNOWN ALREADY There have been numerous studies on the live birth rate of the first FET cycle in patients with PPOS-related protocols. These studies have focused mainly on comparing pregnancy outcomes with those of other stimulation protocols. However, owing to the unique features of the PPOS-related strategy, such as its flexible timing of oocyte retrieval and repeated transfer of frozen embryos, studies using the CLBR as an overall indicator of success and investigating which types of patients would benefit from this protocol are lacking. STUDY DESIGN SIZE DURATION This retrospective cohort study included 18 593 women who underwent PPOS-related protocols (dydrogesterone + hMG, medroxyprogesterone acetate + hMG, micronized progesterone + hMG treatment, and luteal-phase ovarian stimulation protocol) from 1 March 2011 to 31 September 2022 in our centre. PARTICIPANTS/MATERIALS SETTING METHODS The population was categorized by female age, number of oocytes retrieved, and AFC in the analysis of CLBR within six FET cycles. The age groups (Groups 1-5, respectively) were <30, 30-34, 35-39, 40-44, and ≥45 years. The number of oocytes retrieved was grouped as 1-5, 6-10, 11-15, 16-20, and >20. AFC was grouped as <5, 5-10, 11-15, and >15. The Kaplan-Meier analysis (optimistic method), which hypothesized that patients who did not continue treatment had the same chance of achieving a live birth as those who continued, and the competing risk method (conservative method) which hypothesized they had no chance of achieving a live birth, were applied. In further analyses, the Cox model and Fine-Gray model were adopted: the former corresponds to the optimistic scenario, and the latter corresponds to the pessimistic scenario. MAIN RESULTS AND THE ROLE OF CHANCE CLBR had a declining trend with female age over six FET cycles (Groups 1-5, respectively: optimistic: 96.9%, 96.6%, 91.4%, 67.3%, and 11.7%; conservative: 87.3%, 85.0%, 74.0%, 41.3%, and 7.5%), requiring more FET cycles to achieve a success rate of at least 50% (Groups 1-5, respectively: optimistic: 2, 2, 2, 4, and >6 cycles; conservative: 2, 2, 2, >,6 and >6 cycles). CLBR showed an increasing trend with the number of oocytes retrieved (Groups 1-5, respectively: optimistic: 93.8%, 94.3%, 95.8%, 96.0%, and 95.6%; conservative: 66.2%, 78.3%, 85.6%, 88.9%, and 91.0%). All groups needed the same number of FET cycles to achieve a success rate of at least 50% (Groups 1-5, respectively: optimistic: 2, 2, 2, 2, and 2 cycles; conservative: 2, 2, 2, 2, and 2 cycles). Furthermore, the CLBR within six FET cycles had an increasing trend with AFC number (Groups 1-4, respectively: optimistic: 89.2%, 94.8%, 95.9%, and 96.3%; conservative: 67.4%, 78.2%, 83.9%, and 88.1%), with all four groups achieving a success rate of at least 50% by the second FET cycle. LIMITATIONS REASONS FOR CAUTION The current research is limited by its retrospective design and single-centre nature, which may restrict the generalizability of our findings. WIDER IMPLICATIONS OF THE FINDINGS This work describes two models (the Kaplan-Meier analysis and the competing risk method) to evaluate the clinical outcome of patients using PPOS-related protocols, which are especially useful for patients of advanced age or those with diminished ovarian reserve. Our findings encourage patients below 45 years old, especially younger than 40 years, and patients with lower AFCs and fewer retrieved oocytes to try this new protocol. Moreover, this study demonstrates the degree of improvement in the CLBR within six FET cycles for patients with different clinical characteristics, providing a valuable point of reference to determine whether to continue ART after a transfer failure. STUDY FUNDING/COMPETING INTERESTS The study was supported by grants from the National Natural Science Foundation of China (82071603 to L.W., 82001502 to Y.L.). There are no conflicts of interest to declare. TRIAL REGISTRATION NUMBER N/A.

Abstract
Introduction: Fetal ventriculomegaly (VM) is associated with neurodevelopmental disorders, partly caused by genetic factor. Methods: To systematically investigate the genetic etiology of fetal VM and related pregnancy outcomes in different subgroups: IVM (isolated VM) and NIVM (non-isolated VM); unilateral and bilateral VM; mild, moderate, and severe VM, a retrospective study including 131 fetuses with VM was carried out from April 2017 to August 2022. Results: 82 cases underwent amniocentesis or cordocentesis, of whom 8 cases (9.8%) were found chromosomal abnormalities by karyotyping. Meanwhile, additional 8 cases (15.7%) with copy number variations (CNVs) were detected by copy number variation sequencing (CNV-seq). The detection rate (DR) of chromosomal abnormalities was higher in NIVM, bilateral VM and severe VM groups. And CNVs frequently occurred in NIVM, bilateral VM and moderate VM groups. In the NIVM group, the incidence of chromosomal aberrations and CNVs in multiple system anomalies (19.0%, 35.7%) was higher than that in single system anomalies (10.0%, 21.1%). After dynamic ultrasound follow-up, 124 cases were available in our cohort. 12 cases were further found other structural abnormalities, and lateral ventricular width was found increased in 8 cases and decreased in 15 cases. Meanwhile, 82 cases underwent fetal brain MRI, 10 cases of brain lesions and 11 cases of progression were additionally identified. With the involvement of a multidisciplinary team, 45 cases opted for termination of pregnancy (TOP) and 79 cases were delivered with live births. One infant death and one with developmental retardation were finally found during postnatal follow-ups. Discussion: CNV-seq combined with karyotyping could effectively improve the diagnostic rate in fetuses with VM. Meanwhile, dynamic ultrasound screening and multidisciplinary evaluation are also essential for assessing the possible outcomes of fetuses with VM.

Pai AHY, Sung YJ, Li CJ, Lin CY, Chang CL. Progestin Primed Ovarian Stimulation (PPOS) protocol yields lower euploidy rate in older patients undergoing IVF. Reprod Biol Endocrinol 2023; 21:72. [PMID: 37550681 PMCID: PMC10408156 DOI: 10.1186/s12958-023-01124-3] [Citation(s) in RCA: 17] [Impact Index Per Article: 8.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Accepted: 07/30/2023] [Indexed: 08/09/2023] Open
Abstract
BACKGROUND To explore if exogenous progestin required for progestin primed ovarian stimulation (PPOS) protocol compromises the euploidy rate of patients who underwent preimplantation genetic testing cycles when compared to those who received the conventional gonadotropin-releasing hormone (GnRH) antagonist protocol. METHODS This retrospective cohort study analyzed 128 preimplantation genetic testing for aneuploidy (PGT-A) cycles performed from January 2018 to December 2021 in a single university hospital-affiliated fertility center. Infertile women aged 27 to 45 years old requiring PGT-A underwent either PPOS protocol or GnRH-antagonist protocol with in-vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) for fertilization. Frozen embryo transfers were performed following each PGT-A cycle. Data regarding the two groups were analyzed using the Statistical Package for Social Sciences (SPSS) version 22.0 (SPSS Inc., Chicago, IL). RESULTS Patients who underwent PPOS treatment had significantly reduced blastocyst formation rate and euploidy rate compared to those who received the GnRH antagonist protocol. Subgroup-analysis was performed by stratifying patients' age into elder and young subgroups (elder: ≥ 38-year-old, young: < 38-year-old). In the elder sub-population, the blastocyst formation rate of the PPOS group was significantly lower than that of the GnRH-antagonist group (45.8 ± 6.1% vs. 59.9 ± 3.8%, p = 0.036). Moreover, the euploidy rate of the PPOS group was only about 20% of that of the GnRH-antagonist group (5.4% and 26.7%, p = 0.006). In contrast, no significant differences in blastocyst formation rate (63.5 ± 5.7% vs. 67.1 ± 3.2%, p = 0.45) or euploidy rate (30.1% vs. 38.5%, p = 0.221) were observed in the young sub-population. Secondary outcomes, which included implantation rate, biochemical pregnancy rate, clinical pregnancy rate, live birth rate, and miscarriage rate, were comparable between the two treatment groups, regardless of age. CONCLUSION When compared to the conventional GnRH-antagonist approach, PPOS protocol could potentially reduce the euploidy rate in aging IVF patients. However, due to the retrospective nature of this study, the results are to be interpreted with caution. Before the PPOS protocol is widely implemented, further studies exploring its efficacy in larger populations are needed to define the optimal patient selection suitable for this method.

Abstract
OBJECTIVE To use causal inference to investigate whether the flare or antagonist protocol is better for poor responders going through controlled ovarian stimulation. DESIGN A retrospective study. SETTING Retrieval cycles from the Society for Assisted Reproductive Technology Clinic Outcomes Reporting System. PATIENTS Patients in the United States underwent autologous in vitro fertilization cycles from 2014 to 2019 using either the flare or antagonist protocol. INTERVENTION Not applicable. MAIN OUTCOME MEASURE Primary outcomes included oocytes retrieved, fertilized oocytes (2PNs), blastocysts, the cumulative live birth rate (CLBR), and cycle cancelation rate. RESULTS After propensity score matching, patients with a predicted poor response (antimüllerian hormone, <0.5) on their first in vitro fertilization cycle had similar outcomes on the antagonist protocol (CLBR of 14.2%, 95% confidence intervals [CIs]: 13.6%, 14.8%) compared with flare (CLBR of 13.6%, 95% CIs: 12.4%, 14.8%). We evaluated patients undergoing a second cycle after having a poor response (<4 oocytes retrieved) on their first cycle. Patients in the antagonist-to-antagonist group had a similar change in outcomes between the first and second cycles (average CLBR improvement of 13.9%, 95% CIs: 12.1%, 15.6%) compared with the antagonist-to-flare group (average CLBR improvement of 14.4%, 95% CIs: 10.9%, 18.3%). In addition, patients in the flare-to-antagonist group had a similar change in outcomes between the first and second cycles (average CLBR improvement of 10.4%, 95% CIs: 6.6%, 14.5%) compared with the flare-to-flare group (average CLBR improvement of 9.0%, 95% CIs: 5.1%, 13.4%). CONCLUSION Poor responders have similar outcomes on an antagonist protocol compared with a flare protocol for both the first and second cycles.
