Abstract
Embryo vitrification is a standard procedure in assisted reproductive technology. Previous studies have shown that frozen embryo transfer is associated with an elevated risk of adverse maternal and neonatal outcomes. This study aimed to explore the effects of mouse blastocyst vitrification on the phenotype of vitrified-warmed blastocysts, their intrauterine and postnatal development, and the long-term metabolic health of the derived offspring. The vitrified-warmed blastocysts (IVF + VT group) exhibited reduced mitochondrial activity, increased apoptotic levels, and decreased cell numbers when compared to the fresh blastocysts (IVF group). Implantation rates, live pup rates, and crown-rump length at E18.5 were not different between the two groups. However, there was a significant decrease in fetal weight and fetal/placental weight ratio in the IVF + VT group. Furthermore, the offspring of the IVF + VT group at an age of 36 weeks had reduced whole energy consumption, impaired glucose and lipid metabolism when compared with the IVF group. Notably, RNA-seq results unveiled disturbed hepatic gene expression in the offspring from vitrified-warmed blastocysts. This study revealed the short-term negative impacts of vitrification on embryo and fetal development and the long-term influence on glucose and lipid metabolism that persist from the prenatal stage into adulthood in mice.

Abstract
STUDY QUESTION Does ambient temperature exposure affect outcomes including clinical pregnancy and live birth in women undergoing IVF? SUMMARY ANSWER Both extreme cold and hot ambient temperatures were significantly associated with adverse pregnancy outcomes of IVF cycles. WHAT IS KNOWN ALREADY Heat exposure has been linked to adverse pregnancy outcomes worldwide. However, the effect of ambient temperature on infertile women undergoing IVF treatment is unclear. STUDY DESIGN, SIZE, DURATION A retrospective cohort study was conducted from a database of 3452 infertile women who underwent their first fresh or frozen embryo transfer in the Shanghai First Maternity and Infant Hospital from April 2016 to December 2020. PARTICIPANTS/MATERIALS, SETTING, METHODS Daily mean ambient temperature exposure for each patient was obtained based on their residential address. Temperature-stratified multiple logistic regression analysis was performed to investigate associations between temperature exposure and pregnancy outcomes after controlling for confounders. Vulnerable sub-groups were identified using forest plots. MAIN RESULTS AND THE ROLE OF CHANCE The clinical pregnancy rate and live birth rate were 45.7% and 37.1%, respectively. Regarding clinical pregnancy, a higher temperature during cold weather was significantly associated with a higher pregnancy rate in the period about 11 weeks before ovarian stimulation (adjusted odds ratio (aOR) = 1.102, 95% CI: 1.012-1.201). Regarding live birth, an increased temperature during cold weather was significantly related to a higher live birth rate in the period after confirmation of clinical pregnancy or biochemical pregnancy, with the aORs of 6.299 (95% CI: 3.949-10.047) or 10.486 (95% CI: 5.609-19.620), respectively. However, a higher temperature during hot weather was negatively associated with the live birth rate in the periods after confirmation of clinical pregnancy or biochemical pregnancy, with the aORs at 0.186 (95% CI: 0.121-0.285) or 0.302 (95% CI: 0.224-0.406), respectively. Moreover, the decline in live birth rates during cold and hot weather was accompanied by increased rates of early miscarriage (P < 0.05). Stratified analyses identified susceptibility characteristics among the participants. LIMITATIONS, REASONS FOR CAUTION Climate monitoring data were used to represent individual temperature exposure levels according to the patient's residential address in the study. We were not able to obtain information of personal outdoor activity and use of indoor air conditioners in this retrospective study, which may affect actual temperature exposure. WIDER IMPLICATIONS OF THE FINDINGS This study highlights that the ambient temperature exposure should be taken into account during IVF treatment and afterwards. There is a need to be alert to extremes in cold and hot ambient temperatures, especially during the period of follicle development and pregnancy. With this knowledge, clinicians can scientifically determine the timing of IVF treatment and reinforce patients' awareness of self-protection to minimize adverse pregnancy outcomes associated with extreme temperatures.

Abstract
This retrospective cohort study aimed to compare clinical outcomes following fresh or frozen embryo transfer (FET) in women with advanced reproductive age (ARA). Women aged 35-45 years who underwent their first autologous fresh or frozen cleavage stage embryo transfer cycle in the Centre for Assisted Reproduction of Shanghai First Maternity and Infant Hospital between January 2016 and December 2020 were included. The primary outcome was live birth after the first embryo transfer of the in vitro fertilization (IVF) cycle. Multiple covariates were used for propensity score matching (PSM) and generalized estimating equations were performed to examine the independent association between FET and live birth. Of the total 1453 patients, 327 patients had FET and 1126 patients had fresh ET. After the PSM procedure, 274 patients were included in each group. The live birth rate was 24.8% in the FET group and 25.2% in the fresh ET group (OR 0.98, 95% CI: 0.67-1.44, P = 0.92). Other pregnancy, perinatal and neonatal outcomes were all comparable between the two groups. This study showed that FET did not improve live birth and other clinical outcomes as compared with fresh embryo transfer in women with ARA who underwent their first IVF cycle.

Abstract
Dormant human oocytes contain a perinuclear super-organelle, called the Balbiani Body, which is not present in mature oocytes. Here, we use confocal imaging to visualize two Balbiani Body markers-mitochondria and the DEAD-box helicase DDX4-in preantral follicles isolated from a 20-year-old female patient. In primordial follicles, mitochondria were concentrated in a ring near the oocyte nucleus, while DDX4 formed adjacent micron-scale spherical condensates. In primary and secondary follicles, the mitochondria were dispersed throughout the oocyte cytoplasm, and large DDX4 condensates were not visible. Our data suggest that the Balbiani Body breaks down during the primordial to primary follicle transition, thus releasing mitochondria and soluble DDX4 protein into the oocyte cytoplasm.

Abstract
Spermatogonial stem cells (SSCs) in the testis support the lifelong production of sperm. SSCs reside within specialized microenvironments called "niches," which are essential for SSC self-renewal and differentiation. However, our understanding of the molecular and cellular interactions between SSCs and niches remains incomplete. Here, we combine spatial transcriptomics, computational analyses, and functional assays to systematically dissect the molecular, cellular, and spatial composition of SSC niches. This allows us to spatially map the ligand-receptor (LR) interaction landscape in both mouse and human testes. Our data demonstrate that pleiotrophin regulates mouse SSC functions through syndecan receptors. We also identify ephrin-A1 as a potential niche factor that influences human SSC functions. Furthermore, we show that the spatial re-distribution of inflammation-related LR interactions underlies diabetes-induced testicular injury. Together, our study demonstrates a systems approach to dissect the complex organization of the stem cell microenvironment in health and disease.

Abstract
Purpose The target population for fertility preservation recently has been expanded from adolescents with cancer undergoing gonadotoxic chemotherapy to include transgender youth before initiating gender-affirming hormone therapy. Patients and providers may have knowledge deficits regarding options for fertility preservation, accessibility, and feasibility of its techniques, and impact of treatment on future fertility. This study describes outcomes of sperm cryopreservation in transgender male-to-female (affirmed female) youth and compares semen parameters with adolescents diagnosed with cancer. Methods Medical records of transgender-affirmed female adolescents and adolescent males diagnosed with cancer who underwent sperm cryopreservation at the Fertility and Advanced Reproductive Medicine clinic of the University of Texas (UT) Southwestern Medical Center between March 2015 and March 2020 were reviewed. Demographic data were recorded and values for sperm parameters (volume, count, total count, motility (%), total motile) were collected. When available, hormone levels (luteinizing hormone, follicle-stimulating hormone, testosterone, and estradiol) and Tanner stages were also assessed. The two populations were compared using chi-square analysis and two-sample student's t-test. Data are presented as mean±standard deviation. Results While semen quality parameters trended lower in transgender youth compared with adolescents with cancer, there was no statistically significant difference between groups. While four out of 18 patients in the transgender group had azoospermia, mean semen quality parameters fell within normal adult reference ranges for both groups. Conclusion Sperm cryopreservation for transgender youth and adolescents with cancer is feasible, inexpensive, and does not result in significant treatment delays. This information can improve counseling and access to these procedures, particularly in the transgender population.

Abstract
Understanding how gene regulatory elements influence ovarian follicle development has important implications in clinically relevant settings. This includes understanding decreased fertility with age and understanding the short-lived graft function commonly observed after ovarian tissue cryopreservation and subsequent autologous transplantation as a fertility preservation treatment. The Assay for Transposase Accessible Chromatin by sequencing (ATAC-seq) is a powerful tool to identify distal and proximal regulatory elements important for activity-dependent gene regulation and hormonal and environmental responses such as those involved in germ cell maturation and human fertility. Original ATAC protocols were optimized for fresh cells, a major barrier to implementing this technique for clinical tissue samples which are more often than not frozen and stored. While recent advances have improved data obtained from stored samples, this technique has yet to be applied to human ovarian follicles, perhaps due to the difficulty in isolating follicles in sufficient quantities from stored clinical samples. Further, it remains unknown whether the process of cryopreservation affects the quality of the data obtained from ovarian follicles. Here, we generate ATAC-seq data sets from matched fresh and cryopreserved human ovarian follicles. We find that data obtained from cryopreserved samples are of reduced quality but consistent with data obtained from fresh samples, suggesting that the act of cryopreservation does not significantly affect biological interpretation of chromatin accessibility data. Our study encourages the use of this method to uncover the role of chromatin regulation in a number of clinical settings with the ultimate goal of improving fertility.

Abstract
In assisted reproductive technology treatment, diminished ovarian reserve (DOR) is a condition of utmost clinical and scientific relevance because of its negative influence on patient outcomes. The current methods of infertility treatment may be unsuitable for many women with DOR, which support the need for development of additional approaches to achieve fertility restoration. Various techniques have been tried to improve the quality and increase the quantity of oocytes in DOR patients, including mitochondrial transfer, activation of primordial follicles, in vitro culture of follicles, and regeneration of oocytes from various stem cells. Herein, we review the science behind these experimental reproductive technologies and their potential use to date in clinical studies for infertility treatment in women with DOR.

Abstract
Objective This prospective study aimed to assess the effect of short-acting
gonadotropin-releasing hormone agonist (GnRHa) administration on pregnancy
outcomes in frozen–thawed embryo transfer (FET) cycles. Methods Patients who planned to have FET in Peking Union Medical College Hospital
(China) were recruited for this study and randomly assigned into two groups.
Patients in the experimental group (n = 460) received triptorelin acetate on
the day of embryo transfer along with routine luteal support. Patients in
the control group (n = 433) only received luteal support. One dose (0.1 mg)
of a short-acting GnRHa was administered on the day of blastocyte transfer.
The rates for clinical pregnancy, biochemical pregnancy, implantation,
miscarriage, and ectopic pregnancy were compared between the groups. Results There were no significant differences in the number and quality of
blastocytes transferred between the two groups. In the experimental and
control groups, the clinical pregnancy rate was 56.3% and 50.58%, the
biochemical pregnancy rate was 15.78% and 18.94%, and the median
implantation rate was 39.98% and 38.01%, respectively, with no significant
difference between the groups. Biochemical pregnancy and abortion and the
ectopic pregnancy rate were not significantly different between the two
groups. Conclusion In FET cycles, a GnRHa does not affect the pregnancy outcome.

Association between ambient air pollution and pregnancy outcomes in patients undergoing in vitro fertilization in Shanghai, China: A retrospective cohort study. Environ Int 2021; 148:106377.

Abstract
BACKGROUND The effects of ambient air pollutants on adverse pregnancy outcomes have been reported. However, studies about air pollutants exposure and pregnancy outcomes in patients undergoing IVF were limited and inconclusive. To date Shanghai has been the only city in China to implement a compulsory single embryo transfer policy for all patients undergoing their first embryo transfer procedure effective from January 2019. We aimed to investigate the associations between exposure to ambient air pollutants and biochemical pregnancy and live births, and to identify potential vulnerability characteristics of patients undergoing IVF in Shanghai, China. METHODS A retrospective cohort study was conducted on 2766 infertile patients aged ≤ 45 years who underwent first fresh or frozen-thawed cleavage stage embryo transfer in the Shanghai First Maternity and Infant Hospital during April 2016 and December 2019. Daily average ambient levels of six air pollutants (PM2.5, PM10, NO2, SO2, CO and O3 max-8h) were obtained from fixed air monitors located in closest proximity to patients' residences. The cumulative average level was calculated during three different exposure periods (period1: three months before oocyte retrieval to serum hCG test; period 2: from serum hCG test to live birth outcome; period 3: from three months before oocyte retrieval to live birth). Multiple logistic regression model was performed to investigate associations between exposure to ambient air pollutants and pregnancy outcomes. Stratified analyses were conducted to explore the potential effects modifier. RESULTS The biochemical pregnancy rate and live birth rate were 54.2% and 36.4%, respectively. The ambient NO2 exposure was significantly associated with a 14% lower pregnancy rate during period 1 (aOR = 0.86, 95%CI: 0.75-0.99). The ambient PM10 was related to significantly increased risk of lowering live birth rate among the patients during period 3 [aOR = 0.88(0.79-0.99)]. Stratified analysis showed that ambient PM10 was also significantly associated with a reduced pregnancy rate (aOR = 0.82, 95% CI: 0.69-0.97) in patients who underwent single embryo transfer during period 1. Subjects who underwent single embryo transfer also had a decreased likelihood of a live birth when exposed to ambient SO2 and O3 during period 3 [aOR = 0.74(0.57-0.95), and 0.92 (0.83-0.98), respectively]. Moreover, O3 exposure was associated with decreased live birth rates in patients living in non-urban areas. Sensitivity analyses indicated robust negative association between PM10 exposure and live birth outcomes. CONCLUSIONS Our study suggested that exposure to ambient air pollutants, in particular NO2 and PM10, was associated with an increased risk of lower rates of pregnancy and live birth respectively in patients undergoing IVF. Stratified analyses indicated that ambient SO2 and O3 levels were related to adverse pregnancy outcomes in some subgroups of IVF patients in this study. Notably, patients who underwent single embryo transfer were more susceptible to ambient air pollution exposure. Thus, prospective cohort studies are needed to investigate the underlying mechanisms and the susceptibility windows for women undergoing IVF treatment.

Abstract
BACKGROUND Early cumulus cell removal combined with early rescue intracytoplasmic sperm injection (ICSI) has been widely practiced in many in vitro fertilization (IVF) centers in China in order to avoid total fertilization failure. However, uncertainty remains whether the pregnancy and neonatal outcomes are associated with early cumulus cell removal. OBJECTIVES To investigate if early cumulus cell removal alone after 4 hours co-incubation of gametes (4 h group), has detrimental effect on the pregnancy and neonatal outcomes in patients undergoing IVF, through a comparison with conventional cumulus cell removal after 20 hours of insemination (20 h group). METHODS This retrospective cohort study included 1784 patients who underwent their first fresh cleavage stage embryo transfer at the Centre for Assisted Reproduction of Shanghai First Maternity and Infant Hospital from June 2016 to December 2018 (4 h group, n=570; 20 h group, n=1214). A logistic regression analysis was performed to examine the independent association between early cumulus cell removal and pregnancy outcomes after adjustment for potential confounders. The neonatal outcomes between the two groups were compared. RESULTS When compared with the 20 h group, the 4 h group had similar pregnancy outcomes, including rates for biochemical pregnancy, clinical pregnancy, ongoing pregnancy, miscarriage, ectopic pregnancy, multiple pregnancy, live birth. There were 1073 infants delivered after embryo transfer (4 h group, n=337; 20 h group, n=736). Outcomes in both groups were similar for both singleton and twin gestations, including preterm birth rate and very preterm birth rate, mean birth weight, mean gestational age, sex ratio at birth and rate of congenital birth defects. In addition, findings pertaining to singleton gestations were also similar in the two groups for Z-scores (gestational age- and sex-adjusted birth weight), rates of small for gestational age, very small for gestational age, large for gestational age and very large for gestational age infants. CONCLUSIONS In this study early cumulus cell removal alone was not associated with adverse pregnancy and neonatal outcomes. From this perspective, early cumulus cell removal to assess for a potential early rescue ICSI is therefore considered to be a safe option in patients undergoing IVF.

Abstract
Although it is well appreciated that ovarian stimulation protocols for in vitro fertilization (IVF) alter endometrial receptivity, the precise cellular mechanisms are not known. To gain insights into potential mechanisms by which different ovarian stimulation protocols alter the endometrium, we compared histologic and gene expression profiles of endometrium from women undergoing conventional ovarian stimulation for IVF (C-IVF) with those undergoing minimal stimulation with clomiphene citrate (MS-IVF). Sixteen women undergoing MS-IVF (n = 8) or C-IVF (n = 8) were recruited for endometrial biopsy at the time of oocyte retrieval. Endometrial glands were large, tortuous, and secretory with C-IVF but small and undifferentiated with MS-IVF. Whereas RNA sequencing did not reveal changes in estrogen receptor or its co-regulators or classic proliferation associated genes in MS-IVF, together with immunohistochemistry, Wnt signaling was disrupted in endometrium from MS-IVF cycles with significant upregulation of Wnt inhibitors. Secreted frizzled-related protein 1 (sFRP1) was increased fourfold (p < 0.01), and sFRP4 was upregulated sixfold (p < 0.01) relative to C-IVF. Further these proteins were localized to subepithelial endometrial stroma. These data indicate that MS-IVF protocols with CC do not seem to impact endometrial estrogen signaling as much as would be expected from the reported antiestrogenic properties of CC. Rather, the findings of this study highlight Wnt signaling as a major factor for endometrial development during IVF cycles.

Abstract
Objective Minimal stimulation IVF is a treatment option that uses clomiphene citrate
(CC). We sought to evaluate how CC impacts endometrial thickness during
minimal stimulation IVF cycles. Methods We retrospectively analyzed a cohort of 230 cycles in 119 poor ovarian
response patients. The IVF cycles were studied in three groups: 130 minimal
stimulation cycles, 29 mild stimulation cycles, and 30 conventional high
dose gonadotropin releasing hormone (GnRH) antagonist cycles. Thirty-three
minimal stimulation IVF patients had 41 frozen embryo transfers (FET) which
allowed us to study whether the CC effects were prolonged. Results Endometrial thickness in the minimal stimulation group was significantly
lower than the mild and conventional stimulation groups (7.3±2.2mm
versus 11.4±3.3mm versus 12.9±3.8mm, respectively,
p<0.0001). In patients who underwent minimal
stimulation IVF followed by FET, significantly thicker endometrial thickness
was achieved during their FET cycles as compared to their minimal
stimulation cycles (7.95±2.1mm versus 10.3±1.8mm,
p<0.0001). Conclusion We concluded that endometrial thickness is impacted during minimal
stimulation IVF cycles. Since negative effects on endometrial thickness are
not observed in the patients’ subsequent FET cycle, a freeze-all approach is
justified to mitigate adverse endometrial effects of CC in minimal
stimulation IVF cycles.

Abstract
INTRODUCTION Obesity is an epidemic affecting more than one-third of adults in the United States. Obese women experience decreased fertility, explained in part by oocyte quality. Since follicular fluid (FF) provides an important microenvironment for oocyte growth, we sought to evaluate the effect of increased body weight on FF levels of 11 metabolic hormones and fatty acid metabolism. METHODS The FF was collected from 25 women (10 normal weight, 10 overweight, and 5 obese) with diminished ovarian reserve undergoing in vitro fertilization (IVF) following a minimal stimulation protocol. Hormone levels were determined by multiplex immunoassay using the MAGPIX (Luminex, Austin, Texas) instrument. Fatty acid metabolites were determined using gas and ultra-high pressure liquid chromatography coupled with mass spectrometry. RESULTS Levels of hormones related to glucose and energy homeostasis and regulation of fat stores (insulin, glucagon, glucagon-like peptide-1, C-peptide, and leptin) were increased significantly in FF from obese women compared to FF from nonobese(normal weight and overweight) women. Interestingly, FF levels of branched-chain amino acids (BCAA) isoleucine, leucine, and valine as well as uric acid, isocaproic acid, butanoic acid, tyrosine, threonine, glycine, and methionine correlated positively with body mass index. CONCLUSION This pilot study demonstrates significant alterations in the FF milieu of obese women undergoing IVF, which may contribute to the decreased fecundity of obese women. Although the impact of this environment on oocyte and embryo development is not fully realized, these changes may also lead to imprinting at the genomic level and long-term sequelae on offspring.

Abstract
BACKGROUND Androgenic compounds have been implicated in induction of endometrial atrophy yet the mechanisms of androgen effects on human endometrium have not been well studied. We hypothesized that androgens may promote their endometrial effects via modulation of progesterone receptor (PR) expression. METHODS Proliferative phase endometrial samples were collected at the time of hysterectomy. We evaluated the effect of the potent androgen 5α-dihydrotestosterone (DHT) on endometrial PR expression by treating human endometrial explants, endometrial stromal cells, and Ishikawa cells with DHT. Ishikawa cells were also treated with DHT ± the androgen receptor (AR) blocker flutamide. The PR-B, total PR messenger RNA (mRNA), and PR protein expression were assessed. Expression of cyclin D1 and D2 was checked as markers of cell proliferation. RESULTS As expected, estradiol induced PR expression in isolated stromal cells, endometrial epithelial cells, and tissue explants. The DHT treatment also resulted in increased PR expression in endometrial explants and Ishikawa cells but not in stromal cells. Further, protein levels of both nuclear PR isoforms (PR-A and PR-B) were induced with the DHT treatment. Although flutamide treatment alone did not affect PR expression, flutamide diminished androgen-induced upregulation of PR in both endometrial explants and Ishikawa cells. Although estradiol induced both cyclin D1 and cyclin D2 mRNA, DHT did not induce these markers of cell proliferation. CONCLUSION Androgens may mediate endometrial effects through upregulation of PR gene and protein expression. Endometrial PR upregulation by androgens is mediated, at least in part, through AR.

Abstract
As women are increasingly delaying childbearing into their 30s and beyond, diminished ovarian reserve (DOR) and advanced reproductive age (ARA) patients are bound to become a large proportion of all assisted reproductive technology practices. Traditional controlled ovarian stimulation (COS) protocols for DOR and/or ARA have had some limited success, but pregnancy rates are lower and cycle cancellation rates are higher than their younger counterparts with normal ovarian reserve. Though many physicians have a selection of favorite standard protocols that they use, patients with DOR may require closer monitoring and customization of the treatment cycle to address the common problems that come with low ovarian reserve. Frequent issues that surface in women with DOR and/or ARA include poor follicular response, premature luteinizing hormone surge, and poor embryo quality. Limited published evidence exists to guide treatment for DOR. However, use of minimal or mild doses of gonadotropins, avoidance of severe pituitary suppression, and consideration for luteal phase stimulation and a "freeze all" approach are possible customized treatment options that can be considered for such patients who have failed more traditional COS protocols.

Abstract
Potential roles of gonadotropin-releasing hormone (GnRH) antagonists on GnRH/GnRH receptor systems and their effects on the extrapituitary tissues are largely elusive. In this narrated review, we summarized the systemic effects of GnRH antagonists on ovary, endometrium, embryo implantation, placental development, fetal teratogenicity, reproductive tissue cancer cells, and heart while briefly reviewing the GnRH and GnRH receptor system. GnRH antagonists may have direct effects on ovarian granulosa cells. Data are conflicting regarding their effects on endometrial receptivity. The GnRH antagonists may potentially have detrimental effect on early placentation by decreasing the invasive ability of cytotrophoblasts if the exposure to them occurs during early pregnancy. The GnRH antagonists were not found to increase the rates of congenital malformations. Comparative clinical data are required to explore their systemic effects on various extrapituitary tissues such as on cardiac function in the long term as well as their potential use in other human cancers that express GnRH receptors.

Abstract
A number of microRNAs (miRNAs), including miR-200 family, are aberrantly expressed in endometriosis and endometrial cancer. Here we assessed the expression and functional aspects of miR-200c in endometrial tissues (N = 52) from normal endometrial biopsies (N = 15), endometrial tissues including those exposed to hormonal therapies (N = 20), and grade I-III endometrial cancer (N = 17). miR-200c expression was elevated in normal endometrial biopsies from mid- and late-luteal phase, and in endometrial tumors as compared to endometrial tissues from peri- and postmenopausal period (P < .05) and its pattern of temporal expression displayed an inverse relationship with the expression of ZEBs. The expression of E-cadherin (CDH1) varied, but expressed at low levels, specifically in endometrial tissues and endometrial tumors. The endometrial expression of ZEBs and CDH1 in patients who were exposed to Depo-Provera and gonadotropin-releasing hormone agonist GnRHa displayed a trend toward lower expression as compared to proliferative phase; however, treatment of Ishikawa cells with 17β-estradiol, progesterone, and medroxy progesterone acetate had modest effects on the expression of miR-200c and ZEBs without affecting CDH1 expression. Gain of function of miR-200c in Ishikawa cells repressed ZEBs, as well as VEGFA, FLT1, IKKβ, and KLF9 expression at transcriptional and translational levels through direct interaction with their respective 3'untranslated regions and increased the rate of their proliferation. These results indicated that endometrial miR-200c expression undergoes dynamic changes during transition from normal into cancerous states; possibly influenced by hormonal milieu and by targeting the expression of specific genes with key regulatory functions in cellular transformation, inflammation, and angiogenesis may influence these events during normal and disease progression.

Abstract
MicroRNAs (miRNAs) which regulate gene expression stability displayed an aberrant expression profile in ectopic endometrium (ECE) as compared to eutopic (EUE) and normal endometrium (NE). We assessed the expression of miR-17-5p, miR-23a, miR-23b and miR-542-3p, their predicted target genes, steroidogenic acute regulatory protein, aromatase and cyclooxygenase-2, and influence of ovarian steroids on their expression in endometrial stromal (ESC) and glandular epithelial cells (GEC). The results indicated a lower expression of miR-23b and miR-542-3p and higher level of miR-17-5p in paired ECE and EUE as compared with NE. These levels were elevated and inversely correlated with the level of expression of their respective target genes in ECE. The expression of these miRNAs and genes was differentially regulated by 17beta- estradiol, medroxyprogesterone acetate, ICI-182780 and RU-486, or their respective combinations in ESC and GEC. We concluded that altered expression of specific miRNAs in ECE, affecting the stability of their target genes expression, has direct implications in pathogenesis of endometriosis.

Abstract
Endometriosis is a complex trait with significant environmental and genetic influences that are likely to affect its phenotype. Natural history of the disease varies from one individual to another. The gold standard of surgical diagnosis is limited in accuracy by visibility and recognition of lesions by the attending surgeon. Several lines of evidence suggest that pelvic endometriosis results from the reflux of viable endometrial tissue through the fallopian tubes. Endometriosis is an inflammatory disease that nuclear factor kappa B pathway may play an important role in its pathogenesis. Endometriotic lesions demonstrate increased aromatase expression in association with increased cyclo-oxygenase-2 expression, especially in red lesions which represent earlier stages of inflammation. Estrogen and progesterone receptor expressions vary according to the morphology and the inflammatory status of the endometriotic lesions. Normal endometrial tissue fragments can adhere and implant to peritoneum. Aromatase expression, a possible intrinsic survival factor for endometrial tissue, is inducible in human endometrial fragments by androstenedione at physiological concentrations found in peritoneal fluid. Inflammatory response to ectopic endometrial tissue, which may vary in each individual seems to be important in disease progression. Current therapies for endometriosis include surgical and medical approaches aimed at cytoreduction or hormonal suppression. However, the disease have tendency to recur in many symptomatic women. Although new management approaches are emerging, properly designed clinical trials are desperately needed in treatment of pain and subfertility associated with endometriosis. Future studies should also focus on identifying risk population to develop preventive strategies, since the treatment of endometriosis is costly and challenging.

Abstract
OBJECTIVE To determine if the anti-Müllerian hormone (AMH), a proposed marker of ovarian aging, decreases with repetitive oocyte donation. DESIGN Retrospective cohort. SETTING Academic. PATIENT(S) Thirty-six young women who underwent three to seven oocyte donation cycles. INTERVENTION(S) Assessor blind determination of AMH levels from serum samples collected during each treatment cycle. MAIN OUTCOME MEASURE(S) Cycle trends of serum AMH levels. RESULT(S) The AMH was the only predictor of oocyte yield in the first cycles. The AMH was negatively associated with donor age and follicle stimulating hormone (FSH) dose used. Serum AMH levels did not show any decrease per treatment cycle basis and per maximum number of oocyte donation cycles performed per woman. Whereas donors who underwent six cycles showed increasing AMH levels when controlled for studied covariates, the slopes of the multiple regression curves were not significantly different from donors who underwent three, four, and five cycles. Clinical outcome assessed by FSH dose/number of oocytes ratio did not show significant change over repetitive cycles. Intercycle variation of AMH in all patients over three cycles was found to be 12.5%, which was within the reported intermenstrual range. CONCLUSION(S) Serum AMH levels do not decrease over repetitive oocyte donation cycles, which may imply that accelerated ovarian aging may not occur in oocyte donors.

Abstract
The interactions between ovarian germ and somatic cells and expression of several intraovarian autocrine/paracrine regulators are major contributing factors in the ovary. These intraovarian mediators regulate various ovarian cellular activities including cell growth, differentiation, and apoptosis, which are critical in follicular development. MicroRNAs (miRNAs) have emerged as key components of posttranscriptional gene expression. Recent evidence generated in mice implicates the regulatory function of miRNAs in oocyte maturation and ovarian follicular development. In the human, miRNAs may target specific gene expression in granulosa cells and participate in establishment and progression of ovarian cancer. Here, we review the currently available information on the expression and potential regulatory functions of miRNAs in the ovary under normal and pathologic conditions. Understanding the underlying mechanisms of how ovarian germ cell and somatic cell miRNAs are regulated and identifying their specific target genes and their functions may lead to the development of strategies to achieve target-specific gene regulation for the prevention and treatment of various ovarian disorders.

Abstract
CONTEXT Up-regulation of aromatase expression in endometrial cells disseminated into the peritoneal cavity may enhance their survival via local estrogen synthesis, which may lead to endometriosis. The factors that mediate induction of aromatase in the endometrium are not well defined, but increased expression of steroidogenic factor (SF)-1 may play a role. OBJECTIVE The objective of the study was to determine whether androstenedione (A4), the predominant sex steroid in peritoneal fluid, regulates endometrial aromatase expression. DESIGN This was a cell/tissue culture study. SETTING The study was conducted at an academic center. METHODS Quantitative real-time PCR, HPLC, and chromatin immunoprecipitation were used in this study. RESULTS Treatment of cultured human endometrial explants and stromal cells with A4 (10 nm) significantly up-regulated expression of aromatase mRNA transcripts containing exon IIa at their 5'-ends. In endometrial stromal cells and the human endometrial surface epithelial (HES) cell line, induction of aromatase mRNA by A4 was associated with increased expression of SF-1. In HES cells, tritiated A4 was metabolized to estradiol, testosterone (T), dihydrotestosterone, and androstanediol. Both estradiol and T, but not nonaromatizable androgens, up-regulated aromatase and SF-1 mRNA in HES cells. Chromatin immunoprecipitation revealed that A4 enhanced recruitment of SF-1 to its response element (-136 bp) upstream of CYP19 exon IIa. This, together with the findings that both estrogen receptor antagonist, ICI 182,780, and aromatase inhibitor, fadrozole, suppressed A4 and T induction of aromatase and SF-1 mRNA, indicates that the inductive effects of A4 and T are mediated by their conversion to estrogens. CONCLUSIONS Exposure of endometrial cells to A4 may enhance CYP19 gene expression through its aromatization to estrogens.

Abstract
Aberrant up-regulation of aromatase in eutopic endometrium and implants from women with endometriosis has been reported. Aromatase induction may be mediated by increased cyclooxygenase-2 (COX-2). Recently, we demonstrated that progesterone receptor (PR)-A and PR-B serve an antiinflammatory role in the uterus by antagonizing nuclear factor kappaB activation and COX-2 expression. PR-C, which antagonizes PR-B, is up-regulated by inflammation. Although estrogen receptor alpha (ERalpha) is implicated in endometriosis, an antiinflammatory role of ERbeta has been suggested. We examined stage-specific expression of aromatase, COX-2, ER, and PR isoform expression in eutopic endometrium, implants, peritoneum, and endometrioma samples from endometriosis patients. Endometrial and peritoneal biopsies were obtained from unaffected women and those with fibroids. Aromatase expression in eutopic endometrium from endometriosis patients was significantly increased compared with controls. Aromatase expression in endometriosis implants was markedly increased compared with eutopic endometrium. Aromatase mRNA levels were increased significantly in red implants relative to black implants and endometrioma cyst capsule. Moreover, COX-2 expression was increased in implants and in eutopic endometrium of women with endometriosis as compared with control endometrium. As observed for aromatase mRNA, the highest levels of COX-2 mRNA were found in red implants. The ratio of ERbeta/ERalpha mRNA was significantly elevated in endometriomas compared with endometriosis implants and eutopic endometrium. Expression of PR-C mRNA relative to PR-A and PR-B mRNA was significantly increased in endometriomas compared with eutopic and control endometrium. PR-A protein was barely detectable in endometriomas. Thus, whereas PR-C may enhance disease progression, up-regulation of ERbeta may play an antiinflammatory and opposing role.

Abstract
OBJECTIVE To analyze the potential association between serum cetrorelix levels and clinical pregnancy outcome in patients who had undergone assisted reproduction cycles with a GnRH antagonist cetrorelix acetate 3-mg injection. DESIGN Retrospective case-control study. SETTING University-affiliated private-assisted reproduction center. PATIENT(S) 130 IVF and intracytoplasmic sperm injection first cycles, treated with the same cetrorelix acetate protocol, in two matched groups according to whether the cycle resulted in clinical pregnancy (n = 56) or not (n = 74). INTERVENTION(S) Cetrorelix acetate administration at 3 mg in a sandwich protocol. MAIN OUTCOME MEASURE(S) Serum cetrorelix concentrations on the day of hCG administration with regard to clinical pregnancy outcome, pre- versus post-hCG percent change in serum E(2) levels and implantation rates. RESULT(S) The cetrorelix serum concentrations were in the range of 0.29 to 5.12 ng/mL. The comparisons between groups with and without clinical pregnancy revealed comparable serum cetrorelix levels. There was no significant correlation between the serum cetrorelix concentrations and percent change in pre- versus post-hCG serum E(2) levels. Serum cetrorelix levels were comparable among patients with various implantation rates. CONCLUSION(S) Although a wide range of serum cetrorelix levels could be detected during a GnRH antagonist cycle, these levels were comparable in patients with and without clinical pregnancies.

Abstract
Therapeutic manipulation of cytokines may be accomplished by inhibition of a particular cytokine using an antagonist or by administering the cytokine itself. Cytokines appear to have a number of physiological roles, and consequently therapeutic implications, in obstetrics and gynaecology. In the central nervous system, interleukin-1 (IL-1) decreases gonadotropin releasing hormone and luteinising hormone levels and increases prolactin levels. Interferon-alpha and -gamma and tumour necrosis factor-alpha have negative effects on sperm motility and penetration rates. Seminal IL-6 and IL-8 levels correlate negatively with fertility. IL-8 seems to be involved in periovulatory events by attracting and activating neutrophils that play a role in timely follicular rupture. Leukaemia inhibitory factor has been shown to be essential for blastocyst implantation. Interleukin-1 may be one of the signals for the onset of human parturition, and may also play a role in the initiation of preterm labour associated with intra-amniotic infection. In a mouse model, pretreatment with subcutaneous IL-1 receptor antagonist (IL-1ra) prevented IL-1-induced preterm parturition, suggesting a role for the use of anticytokine agents in the treatment of infection-associated preterm labour. IL-8 induces cervical ripening when applied locally to the cervix in rabbits, which indicates its pivotal role in cervical maturation. The evaluation of cytokine levels, especially IL-1, may be used as a diagnostic tool to monitor osteoporosis, and drugs such as IL-1ra that interfere with cytokine action could provide new therapies for the effective management of postmenopausal osteoporosis. In spite of all these possibilities, current cytokine-based therapies are still experimental, and numerous problems need to be resolved before they are used in routine clinical applications.

Abstract
OBJECTIVE To determine whether women with hydrosalpinx would have diminished endometrial HOXA10 expression and whether salpingectomy would reverse HOXA10 suppression. The homeobox gene HOXA10 is a transcription factor that is necessary for embryo implantation; its expression in human endometrium correlates with receptivity and implantation. Increased endometrial HOXA10 expression may be one mechanism by which salpingectomy results in increased implantation rates in IVF. DESIGN Prospective clinical trial. SETTING Academic medical center. PATIENT(S) Women with unilateral or bilateral hydrosalpinx. INTERVENTION(S) Expression of HOXA10 was examined prospectively during the midluteal phase in endometrium obtained from infertile women (n = 9) with hydrosalpinges before and after salpingectomy, as well as from fertile controls (n = 6). Quantitative HOXA10 mRNA expression was determined by real-time reverse-transcription polymerase chain reaction, and HOXA10 protein expression was determined by immunohistochemistry. MAIN OUTCOME MEASURE(S) Expression of HOXA10 mRNA and protein. RESULT(S) Expression of HOXA10 mRNA was significantly lower in infertile women with hydrosalpinges, compared with the case of fertile controls. Salpingectomy resulted in a statistically significant, 15-fold increase in endometrial HOXA10 expression. Immunohistochemical analysis confirmed the quantitative real-time reverse-transcription polymerase chain reaction findings. Increased HOXA10 expression was evident in both glandular epithelial cells and endometrial stroma. CONCLUSION(S) HOXA10 is necessary for implantation. Here, we demonstrate decreased HOXA10 expression in response to hydrosalpinx fluid as a potential molecular mechanism for diminished implantation rates. Salpingectomy restores endometrial HOXA10 expression. This may be one mechanism by which salpingectomy results in augmented implantation rates in IVF.

Abstract
Uterine myomas are the most common solid pelvic tumors in women and the primary indication for hysterectomy. Most of the myomas are asymptomatic. The most common symptoms associated with uterine myomas are abnormal uterine bleeding and pelvic discomfort mostly caused by the mass effect. Vaginal bleeding may lead to iron deficiency anemia. Uterine myomas have a significant role in reproductive dysfunction, although a causal relationship between infertility and intramural or subserosal myomas not disturbing the uterine cavity has not been established clearly. Nevertheless myomas, especially the tumors distorting the uterine cavity, are associated with infertility and spontaneous miscarriage. In addition, the myomas may be the potential cause for numerous obstetric complications, especially if they are located adjacent to placenta. The transformation of myomas to leiomyosarcomas is a very rare event. Leiomyosarcomas may be suspected in postmenopausal women with rapidly growing symptomatic solid pelvic mass. Despite the high prevalence of these tumors, there is paucity of data available regarding the natural clinical history of myomas.

Abstract
The outcome of a novel protocol utilizing precycle gonadotrophin-releasing hormone (GnRH) antagonist administration and LH activity support with microdose recombinant human chorionic gonadotrophin (HCG) was compared to GnRH agonist long protocol used in patients undergoing their first ICSI (n=707) or IVF (n=571) cycles, which had resulted in one or two blastocyst transfers. In GnRH antagonist cycles, cetrorelix acetate (3 mg) was administered s.c. 4 days before FSH stimulation and a repeat dose was given when the lead follicular diameter was 13-14 mm. LH support was provided by recombinant HCG (2.5 microg). Embryo progression and blastulation were evaluated using embryo progression indices and blastocyst quality scores. The tested protocol demonstrated reduced implantation and clinical pregnancy rates as compared with GnRH agonist long protocol, although the embryo progression and blastulation parameters and blastocyst quality were comparable among the groups. Logistic regression models further supported the significant negative impact of GnRH antagonist/microdose HCG protocol on clinical pregnancy rates in both ICSI and IVF patients. Assisted reproduction cycles with fresh blastocyst transfers utilizing precycle GnRH antagonist administration and microdose HCG support resulted in lower implantation and clinical pregnancy rates as compared with GnRH agonist cycles, although the embryo progression and blastulation parameters were comparable.
