Abstract
The mechanisms and aetiology underlying the development of premature ovarian insufficiency (POI) are poorly understood. However, the oocyte clearly has a role as demonstrated by the Double Mutant (DM) mouse model where ovarian dysfunction (6 weeks) is followed by POI (3 months) due to oocyte-specific deletion of complex and hybrid N- and O-glycans. The ovaries of DM mice contain more primary follicles (3a stage) accompanied by fewer developing follicles, indicating a block in follicle development. To investigate this block, we first analysed early follicle development in postnatal (8-day), pre-pubertal (3-week) and post-pubertal (6-week and 3-month) DM (C1galt1 F/F Mgat1 F/F:ZP3Cre) and Control (C1galt1 F/F Mgat1 F/F) mice. Second, we investigated if transplantation of DM ovaries into a "normal" endocrine environment would restore follicle development. Third, we determined if replacing DM ovarian somatic cells would rescue development of DM oocytes. At 3-week, DM primary 3a follicles contain large oocytes accompanied by early development of a second GC layer and increased GC proliferation. At 6-week, DM primary 3a follicles contain abnormally large oocytes, accompanied with decreased GC proliferation. Transplantation of DM ovaries into a 'normal' endocrine environment did not restore normal follicle development. However, replacing somatic cells by generating reaggregated ovaries (ROs) did enable follicle development to progress and thus highlighted intra-ovarian factors were responsible for the onset of POI in DM females. Thus, these studies demonstrate oocyte-initiated altered communication between GCs and oocytes results in abnormal primary follicles which fail to progress and leads to POI.

Abstract
BACKGROUND Premature ovarian insufficiency (POI) is a clinical syndrome resulting from loss of ovarian function before the age of 40. It is a state of hypergonadotropic hypogonadism, characterised by amenorrhoea or oligomenorrhoea, with low ovarian sex hormones (oestrogen deficiency) and elevated pituitary gonadotrophins. POI with primary amenorrhoea may occur as a result of chromosomal and genetic abnormalities, such as Turner syndrome, Fragile X, or autosomal gene defects; secondary amenorrhoea may be iatrogenic after the surgical removal of the ovaries, radiotherapy, or chemotherapy. Other causes include autoimmune diseases, viral infections, and environmental factors; in most cases, POI is idiopathic. Appropriate replacement of sex hormones in women with POI may facilitate the achievement of near normal uterine development. However, the optimal effective hormone therapy (HT) regimen to maximise the reproductive potential for women with POI remains unclear. OBJECTIVES To investigate the effectiveness and safety of different hormonal regimens on uterine and endometrial development in women with POI. SEARCH METHODS We searched the Cochrane Gynaecology and Fertility (CGF) Group trials register, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, and two trials registers in September 2021. We also checked references of included studies, and contacted study authors to identify additional studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) investigating the effect of various hormonal preparations on the uterine development of women diagnosed with POI. DATA COLLECTION AND ANALYSIS We used standard methodological procedures recommended by Cochrane. The primary review outcome was uterine volume; secondary outcomes were endometrial thickness, endometrial histology, uterine perfusion, reproductive outcomes, and any reported adverse events. MAIN RESULTS We included three studies (52 participants analysed in total) investigating the role of various hormonal preparations in three different contexts, which deemed meta-analysis unfeasible. We found very low-certainty evidence; the main limitation was very serious imprecision due to small sample size. Conjugated oral oestrogens versus transdermal 17ß-oestradiol We are uncertain of the effect of conjugated oral oestrogens compared to transdermal 17ß-oestradiol (mean difference (MD) -18.2 (mL), 95% confidence interval (CI) -23.18 to -13.22; 1 RCT, N = 12; very low-certainty evidence) on uterine volume, measured after 12 months of treatment. The study reported no other relevant outcomes (including adverse events). Low versus high 17ß-oestradiol dose We are uncertain of the effect of a lower dose of 17ß-oestradiol compared to a higher dose of 17ß-oestradiol on uterine volume after three or five years of treatment, or adverse events (1 RCT, N = 20; very low-certainty evidence). The study reported no other relevant outcomes. Oral versus vaginal administration of oestradiol and dydrogesterone We are uncertain of the effect of an oral or vaginal administration route on uterine volume and endometrial thickness after 14 or 21 days of administration (1 RCT, N = 20; very low-certainty evidence). The study reported no other relevant outcomes (including adverse events). AUTHORS' CONCLUSIONS No clear conclusions can be drawn in this systematic review, due to the very low-certainty of the evidence. There is a need for pragmatic, well designed, randomised controlled trials, with adequate power to detect differences between various HT regimens on uterine growth, endometrial development, and pregnancy outcomes following the transfer of donated gametes or embryos in women diagnosed with POI.

Abstract
Estrogen mainly binds to estrogen receptors (ERs) to regulate menstrual cycles and reproduction. The expression of ERalpha (ERα), ERbeta (ERβ), and G-protein-coupled estrogen receptor (GPER) mRNA could be detected in ovary, suggesting that they play an important role in estrogen signal transduction in ovary. And many studies have revealed that abnormal expression of estrogen and its receptors is closely related to ovarian disease or malignant tumors. With the continuous development and research of animal models, tissue-specific roles of both ERα and ERβ have been demonstrated in animals, which enable people to have a deeper understanding of the potential role of ER in regulating female reproductive diseases. Nevertheless, our current understanding of ERs expression and function in ovarian disease is, however, incomplete. To elucidate the biological mechanism behind ERs in the ovary, this review will focus on the role of ERα and ERβ in polycystic ovary syndrome (PCOS), ovarian cancer and premature ovarian failure (POF) and discuss the major challenges of existing therapies to provide a reference for the treatment of estrogen target tissue ovarian diseases.

Abstract
We recently reported the application of human menstrual blood stem cells' (HuMenSCs) transplantation as a treatment modality in a rat model of premature ovarian failure (POF). We continued to investigate further in this respect. Female rats were injected intraperitoneally with 36 mg/kg busulfan. HuMenSCs were obtained, grown, and analyzed for immunophenotypic features at passage three. The cells were labeled with CM-Dil and infused into the rats. There were four groups: normal, negative control, treatment, and Sham. One month after treatment, the ovaries were collected and weighed. Histological sections were prepared from the ovary and HuMenSCs were tracking. Subsequently, we examined the changes of expression of Bax and B cell lymphoma 2 (Bcl2) genes by real-time polymerase chain reaction assay. One month after HuMenSCs transplantation, these cells were located in the ovarian interstitium and granulosa cells (GCs). The number of TUNEL-positive cells significantly decreased in the treatment group. Also the expression level of Bax genes, unlike Bcl2 gene, significantly decreased compared with negative and sham groups. In our study, HuMenSCs were tracked in ovarian tissues within 2 months after transplantation, and they differentiated into GCs. Therefore, the use of these cells can be a practical and low-cost method for the treatment of POF patients.

Abstract
The developmental potential of early embryos is mainly dictated by the quality of the oocyte. Here, we explore the utility of the maternal spindle transfer (MST) technique as a reproductive approach to enhance oocyte developmental competence. Our proof-of-concept experiments show that replacement of the entire cytoplasm of oocytes from a sensitive mouse strain overcomes massive embryo developmental arrest characteristic of non-manipulated oocytes. Genetic analysis confirmed minimal carryover of mtDNA following MST. Resulting mice showed low heteroplasmy levels in multiple organs at adult age, normal histology and fertility. Mice were followed for five generations (F5), revealing that heteroplasmy was reduced in F2 mice and was undetectable in the subsequent generations. This pre-clinical model demonstrates the high efficiency and potential of the MST technique, not only to prevent the transmission of mtDNA mutations, but also as a new potential treatment for patients with certain forms of infertility refractory to current clinical strategies.

Abstract
The molecular mechanisms underlying the activation of primordial follicles are poorly understood. The serine/threonine protein kinase phosphoinositide‑dependent kinase 1 (PDK1), a pivotal downstream effector of phosphatidyl inositol‑3 kinase (PI3K) signaling, plays a vital role in cellular signaling. In order to identify the function of PDK1 in ovarian follicle development, this study used conditional Pdk1 deletion in mouse oocytes by crossing Pdk1loxP/loxP mice with transgenic mice carrying Gdf‑9 promoter‑mediated Cre recombinase and found that Pdk1flx/flxGdf9Cre mice were subfertile with increased serum follicle‑stimulating hormone (FSH) and luteinizing hormone (LH) levels compared with Pdk1flx/flx mice. The deletion of Pdk1 in oocytes induced massive primordial follicle activation, leading to premature ovarian failure (POF). Further investigation revealed that enhanced Yes‑associated protein (YAP) expression and an increased pro‑inflammatory response also contributed to massive primordial follicle activation. PDK1 formed the complex with the core kinases of Hippo signaling and regulated the expression levels of YAP. On the whole, the findings of the present study demonstrate that PDK1 serves as an indispensable gatekeeper for maintaining the primordial follicle pool and provide a deeper understanding of POF treatment.

Abstract
PURPOSE To evaluate the effect of 12-month DHEA supplementation on menstrual pattern and ovarian reserve markers in women with premature ovarian insufficiency (POI) METHODS: This is a prospective observational study. Women with POI were given DHEA supplements (25 mg three times daily) for 12 months. Sonographic assessment for ovarian volume and antral follicle count (AFC) and serum measurement for anti-Mullerian hormone (AMH), follicle stimulating hormone (FSH), estradiol, testosterone, liver function, and hemoglobin level were performed at baseline and monthly for 13 months after the supplementation. Menstrual pattern, ovarian reserve markers, and side-effects were recorded. RESULTS Between August 2011 and July 2014, 38 women with POI were recruited and 31 completed the study. The median age of women was 36 years, and the median baseline FSH and AMH concentrations were 82.2 IU/L and 0.01 ng/ml, respectively. No women had resumption of regular menstruation after DHEA supplementation. AMH, FSH, and AFC did not change significantly. No serious side effects were reported. CONCLUSIONS Our results do not support any significant improvement in ovarian function by 12-month DHEA supplementation in women with POI.

Abstract
BACKGROUND There are very few biomarkers available to diagnose cases with premature ovarian failure. Some complete blood count parameters have been introduced to be diagnostic biomarkers for several disorders associated with inflammatory process. Due to the evidence that indicated chronic inflammatory process to be underlying pathophysiology in premature ovarian insufficiency (POI), we aimed to assess the predictive value of complete blood count parameters for POI diagnosis. METHOD A total of 96 women diagnosed to have premature ovarian failure were compared with 110 otherwise healthy women in terms of some basal hormone levels and complete blood count parameters. RESULTS Mean age was similar between groups. Neutrophil/lymphocyte and mean platelet volume/lymphocyte ratios were significantly higher in group with POI (P < .001, P < .003, respectively). In group with POI, there were significant correlations between anti-Mullerian hormone and follicle stimulating hormone (r = -.30, P <.05), anti-Mullerian hormone and white blood cell count (r = .23, P < .05). Mean platelet volume/lymphocyte ratio significantly predicted cases with POI (AUC = 0.607, %95 CI: 0.529-0.684; P < .001). CONCLUSIONS Neutrophil/lymphocyte and mean platelet volume/lymphocyte ratios are elevated in POI. There have been some controversies about the value of neutrophil/lymphocyte in POI diagnosis. We suggest mean platelet volume/lymphocyte ratio as a new biomarker in early POI because it is cheap and easily accessible compared to anti-Mullerian hormone.

Abstract
This study was to investigate the bidirectional estrogen-like effects of genistein on murine experimental autoimmune ovarian disease (AOD). Female BALB/c mice were induced by immunization with a peptide from murine zona pellucida. The changes of estrous cycle, ovarian histomorphology were measured, and the levels of serum sex hormone were analyzed using radioimmunoassay. Proliferative responses of the ovary were also determined by immunohistochemistry. Administration of 25 or 45 mg/kg body weight genistein enhanced ovary development with changes in serum sex hormone levels and proliferative responses. Meanwhile, the proportions of growing and mature follicles increased and the incidence of autoimmune oophoritis decreased, which exhibited normal ovarian morphology in administration of 25 or 45 mg/kg body weight genistein, while a lower dose (5 mg/kg body weight genistein) produced the opposite effect. These findings suggest that genistein exerts bidirectional estrogen-like effects on murine experimental AOD, while a high dose (45 mg/kg body weight) of genistein may suppress AOD.

Abstract
Premature ovarian insufficiency (POI) occurs in 1% of women under 40 years of age and is predominantly idiopathic. In a transgenic mouse model of follicular POI, the Double Mutant (DM), female mice are fertile at 6 weeks of age, become infertile by 9 weeks and exhibit POI by 3 months. DM female mice generate oocytes lacking mucin O-glycans and complex N-glycans due to deletion of core 1 synthase, glycoprotein-N-acetylgalactosamine 3-β-galactosyltransferase 1 (C1galt1) and mannoside acetylglucosaminyltransferase 1 (Mgat1) respectively (DM, C1galt1F/FMgat1F/F:ZP3Cre; Control, C1galt1F/FMgat1F/F). To determine whether DM follicle development could be improved in a controlled environment, follicles from DM and Control mice were cultured individually and follicle growth, morphology, survival and antrum formation were evaluated. DM ovaries were more rigid than Control ovaries at 3, 6 and 9 weeks, which was exacerbated with age, resulting in a failure to isolate follicles from 9 week-old DM females. DM follicles had decreased survival compared with Control follicles from females at 3 and 6 weeks of age. Furthermore, survival rate of DM follicles decreased with age between 3 and 6 weeks. DM follicles at both 3 and 6 weeks had accelerated follicle growth and altered antrum formation during the first few days of culture but, after 6 days, follicles were equivalent in size to the Controls. In conclusion, a population of DM follicles retain the potential to develop in vitro, and therefore follicle culture offers a reliable method to generate antral follicles from preantral follicles after the onset of POI in these female mice.

Abstract
Premature menopause, that is, menopause – spontaneous or iatrogenic – occurring at or before the age of 40 years, affects sexual identity, sexual function and sexual relationships. The woman's health, wellbeing and achievement of life's goals may be variably impaired. Factors modulating the individual's sexual outcome after premature menopause include: etiological heterogeneity of premature menopause and associated medical and sexual comorbidities; psychosexual vulnerability to premature menopause and associated infertility in survivors of childhood and adolescent cancers; impact of premature menopause on women's sexual identity, sexual function – particularly the biological basis of desire, arousal, orgasm and vaginal receptivity – and sexual relationships; partner-related factors; fertility issues; and preventive/therapeutic measures. Hormone therapy is indicated but long-term safety data are lacking. An interdisciplinary medical and psychosexual approach comprises appropriate counseling, fertility protection, when feasible, individualized hormone therapy and specific psychosexual treatment(s). Further research on fertility protection and the safety of long-term hormone therapy after premature menopause is needed.

Abstract
Premature ovarian insufficiency (POI) occurs in 1% of reproductive-age women. The ovarian manifestation ranges from the presence of a variable population of follicles (follicular) to the absence of follicles (afollicular), and in the majority of cases the cause is unknown. A transgenic mouse model of follicular POI, the Double Mutant (DM), arises from oocyte-specific deletion of Mgat1 and C1galt1 required for the generation of O- and N-glycans. DM females are subfertile at 6 weeks, infertile by 9 weeks and exhibit POI by 12 weeks of age. In this study we investigate the cause of the reduced fertility at 6 weeks and infertility at 9 weeks of DM females. Ovary sections were used to analyse follicle and corpora lutea (CL) numbers, apoptosis, and levels of laminin and 3β-hydroxysteroid dehydrogenase using immunohistochemistry. After POI, DM females unexpectedly remained sexually receptive. At both 6 and 9 weeks, DM ovaries contained more primary follicles, however, at 9 weeks DM follicles were proportionally healthier, revealed by TUNEL analysis compared with Controls. In 9 week DM ovaries (collected post-mating), secondary follicles had theca and basal lamina structure abnormalities, whilst preovulatory follicles failed to ovulate resulting in the presence of numerous luteinised unruptured follicles, indicative of ovulation failure. Finally, DM ovaries contained more regressing CL with decreased luteal cell apoptosis indicative of a defect in CL regression. Identifying these follicular modifications have provided insight into the aetiology of a model of POI and highlight targets to investigate with the hope of developing new fertility treatments.

Abstract
The narrow standard age range of menopause, ∼50 yr, belies the complex balance of forces that govern the underlying formation and progressive loss of ovarian follicles (the "ovarian reserve" whose size determines the age of menopause). We show here the first quantitative graph of follicle numbers, distinguished from oocyte counts, across the reproductive lifespan, and review the current state of information about genetic and epidemiological risk factors in relation to possible preservation of reproductive capacity. In addition to structural X-chromosome changes, several genes involved in the process of follicle formation and/or maintenance are implicated in Mendelian inherited primary ovarian insufficiency (POI), with menopause before age 40. Furthermore, variants in a largely distinct cohort of reported genes-notably involved in pathways relevant to atresia, including DNA repair and cell death-have shown smaller but additive effects on the variation in timing of menopause in the normal range, early menopause (age <45), and POI. Epidemiological factors show effect sizes comparable to those of genetic factors, with smoking accounting for about 5% of the risk of early menopause, equivalent to the summed effect of the top 17 genetic variants. The identified genetic and epidemiological factors underline the importance of early detection of reproductive problems to enhance possible interventions.

Abstract
Premature ovarian failure (POF) affects up to 1.4% of women under the age of 40 yr and less than 30% of cases have a known cause. Here we describe a new mouse model of POF resulting from oocyte-specific ablation of core 1-derived (mucin) O-glycans and complex and hybrid N-glycans. Females carrying floxed alleles of both the C1galt1 (T-syn) and Mgat1 glycosyltransferase genes and a ZP3Cre transgene, generate oocytes lacking complex O- and N-glycans following oocyte-specific deletion at the primary follicle stage. We previously showed that few double-mutant females are fertile, and those produce only a single small litter. Here we show that ovarian function declined rapidly in double-mutant females with less than 1% ovulating at 11 wk of age after superovulation with exogenous gonadotropins. Ovary weight was significantly decreased in double-mutant females by 3 months of age, consistent with a decrease in the number of developing follicles. FSH levels in double-mutant females were elevated at 3 months of age, and testosterone and inhibin A were decreased, showing that the loss of complex N- and O-glycans from oocyte glycoproteins affected hypothalamic-pituitary-gonadal feedback loops. The absence of developing follicles, ovary dysfunction, reduced testosterone and inhibin A, and elevated FSH in double-mutant females lacking C1galt1 and Mgat1 in oocytes represents a new mouse model for the study of follicular POF.

Abstract
BACKGROUND Chemotherapy-induced ovarian failure (CIOF) is a frequent side-effect of adjuvant chemotherapy that results in rapid bone loss. We hypothesised that zoledronic acid (ZA), a third-generation amino bisphosphonate, would prevent bone loss in premenopausal women who developed CIOF. METHODS Women (439) were randomised to intravenous (i.v.) ZA 4 mg every 3 months for 2 years starting within 1-3 months after randomization (arm A) or 1 year after randomization (arm B, controls). CIOF was prospectively defined as ≥ 3 months of amenorrhoea, follicle-stimulating hormone (FSH) ≥ 30 MIU/ml and non-pregnant at 1 year. The primary end-point was the percentage change in bone mineral density (BMD) in the lumbar spine (LS) from baseline to 12 months in the ZA and in control groups in women who developed CIOF; the secondary end-point was BMD in LS at 3 years in all randomised women. FINDINGS One hundred and fifty (56%) met the definition of CIOF at 1 year. Overall, grade 3 toxicities of ZA were fatigue (1%) arthralgias (21%) and pain (84%). The median percent change (interquartile range, IQR) at 1 year was +1.2% (-0.5% to +2.8%) and -6.7% (-9.7% to -2.9%) p<0.001 and at 3 years was +1.0% (-1.6% to +5.2%) and -0.5% (-3.7% to +3.2%) p=0.019 in arms A and B, respectively. INTERPRETATION ZA every 3 months is well tolerated and prevents rapid bone loss in premenopausal women that develop CIOF. Giving ZA with rather than 1 year after the start of adjuvant chemotherapy is the preferred sequence to prevent bone loss.

Abstract
PURPOSE OF REVIEW To review the pathogenesis of premature ovarian insufficiency due to steroid cell autoimmunity (SCA-POI). RECENT FINDINGS Autoimmune oophoritis is characterized by a selective mononuclear cell infiltration into the theca layer of large, antral follicles, with earlier stage follicles consistently free of lymphocytic infiltration. SCA-POI is caused by the selective autoimmune destruction of theca cells with preservation of granulosa cells that produce low amounts of estradiol because of lack of substrates. Typically, serum concentrations of inhibins are increased in women with SCA-POI, as compared to both healthy fertile women and women with other forms of ovarian insufficiency. Normal serum antimüllerian hormone (AMH) concentrations were detected in two-thirds of women with recently diagnosed SCA-POI, which demonstrates that this form of ovarian insufficiency is associated with a preserved pool of functioning follicles. SUMMARY The combined measurement of autoantibodies and markers of ovarian reserve (as inhibin B and AMH) may permit to identify women with POI due to steroid cell autoimmunity with a preserved proportion of primordial and primary follicles. In the future the development of techniques of in-vitro folliculogenesis may permit new treatment strategies for women with SCA-POI-related infertility.

Abstract
Premature ovarian failure (POF) is a syndrome characterised by amenorrhoea, hypoestrogenism and hypergonadotropinism before the age of 40. It is a disorder affecting approximately 1% of women <40 years, 1/1,000 women by the age of 30 and 1/10,000 women by the age of 20. POF is not merely an early menopause. Up to 50% of the patients with POF will have intermittent and unpredictable ovarian function which may persist for some years. Heterogeneity of POF is also reflected by the variety of possible causes, including autoimmunity, toxics, drugs, radiation, infectious as well as genetic defects. HRT remains the cornerstone of treatment and the only proven method of achieving pregnancy in these patients is by ovum donation.

Abstract
This article focuses on primary ovarian insufficiency and the experimental models used in recent years to explain the probable mechanisms of autoimmune oophoritis and idiopathic primary ovarian insufficiency. The relationship between the immune system and the neuroendocrine system is also an important focus of this article. Activation of the immune system is necessary for maintaining homeostasis and this requires multiple interactions and regulation between the immune system and the neuroendocrine system. Neuropeptides, neuroendocrine mediators, are expressed and released primarily, but not exclusively, by the nervous system and have profound effects on the immune system. As an example of one of these peptides we describe the α-melanocyte-stimulating hormone and its anti-inflammatory properties.

Abstract
In addition to cancers, many non-oncological conditions, including chromosomal abnormalities and autoimmune disorders, are currently treated with gonadotoxic agents that can lead to premature ovarian failure. Because of the young age of some of the women affected by these conditions, attempts to preserve fertility and ovarian function are recommended. To date, retrieval of immature oocytes followed by in-vitro maturation and vitrification has been found to be especially useful for women who cannot undergo ovarian stimulation, or when there is a contraindication.

Abstract
OBJECTIVE To assess the glycoform distribution patterns of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) during the menstrual cycle at different ages and FSH levels, after menopause, and with premature ovarian failure (POF). DESIGN Controlled clinical study. SETTING Healthy volunteers in an academic research environment. PATIENT(S) Women aged 20 to 25 years with normal early follicular (EF) serum FSH (<10 IU/L), women aged 40 to 45 years with normal or increased EF serum FSH, postmenopausal women, and women with POF. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) FSH and LH glycoform distributions as assessed by chromatofocusing. RESULT(S) In both postmenopausal and in women with POF, more acidic FSH glycoforms were found compared with young cyclic premenopausal women. In women aged 40 to 45 years with normal FSH levels, these acidic glycoform profiles already showed a statistically significant difference from the younger women. This difference was to attributable to the early follicular and luteal cycle phases. Overall, during aging and after ovarian failure, FSH becomes more acidic, a difference that is already statistically significantly detectable in premenopausal, older women before FSH rises. This is not seen for LH glycoforms. CONCLUSION(S) The occurrence of postmenopausal-like acidic FSH isoforms precedes the rise of FSH before menopause.

Abstract
We investigated the presence of mutations/polymorphisms in the FSH receptor (FSHR) gene and their association with phenotype in women with premature ovarian failure (POF) in southern Brazil. Clinical and hormonal variables were determined in 36 46,XX women with primary or secondary amenorrhea before the age of 40 yr, FSH >40 IU/l and ovarian failure. DNA was isolated from peripheral leukocytes. Exons 6, 7, 9, and 10 of the FSHR gene were analyzed by PCR, restriction enzyme analysis, denaturing gradient gel electrophoresis, and direct sequencing. No inactivating mutations were found. Exon 10 had two polymorphisms, Ala307Thr and Ser680Asn (allelic frequency: 52.9 and 35.7%, respectively), which were not related to FSH, LH or estradiol serum levels. Ovarian size and small ovarian follicles on transvaginal sonography were not associated with FSHR genetic variants. In contrast, the last menstruation occurred significantly earlier in patients with the Ala307Thr polymorphism (A: age=33.3+/-7.1 yr vs T: 28.6+/-11.4 yr, p=0.04). In conclusion, we did not identify inactivating mutations in exons 6, 7, 9, and 10 of the FSHR gene. A high frequency of two polymorphisms that are in linkage disequilibrium was found in exon 10 of the FSHR gene. The presence of the Ala307Thr polymorphism may be associated with a more precocious onset of clinical disease.

Since the first successful birth at our center following treatment with DHEA in a patient with premature ovarian failure (POF), all subsequent patients with POF underwent the same treatment protocol. Receiving very encouraging results (FSH level was decreased in the first five patients and all achieved pregnancy), it was decided to study the action of DHEA for a reasonable length of time and in a larger number of patients to confirm the effectiveness of this particular therapeutic regime.

Abstract
The action of estrogen in the female reproductive organs is well known in terms of the expression pattern and gene regulation of the estrogen receptor (ER). The significance of ERs in female reproduction is undisputed. The role of the androgen receptor (AR) is less clear. Clinical hyperandrogenism, a typical feature of polycystic ovary syndrome (PCOS), highlights pathological androgen production by the ovary. By contrast, the physiological impact of androgen action in female reproductive organs remains elusive. Androgens affect folliculogenesis in a variety of experimental approaches and ARs are expressed in developing follicles. Recent observations have discovered that inactivation of ARs in female mice results in premature ovarian failure (POF), indicating that normal folliculogenesis requires AR-mediated androgen action. Moreover, these results imply that POF might be caused by impairment of AR-mediated androgen action.

Abstract
An origin of bidirectional DNA replication was mapped to the promoter of the FMR1 gene in human chromosome Xq27.3, which has been linked to the fragile X syndrome. This origin is adjacent to a CpG island and overlaps the site of expansion of the triplet repeat (CGG) at the fragile X instability site, FRAXA. The promoter region of FMR2 in the FRAXE site (approximately 600 kb away, in chromosome band Xq28) also includes an origin of replication, as previously described [Chastain II, P.D., Cohen, S.M., Brylawski, B.P., Cordeiro-Stone, M., Kaufman, D.G., 2006. A late origin of DNA replication in the trinucleotide repeat region of the human FMR2 gene. Cell Cycle 5, 869-872]. FMR1 transcripts were detected in foreskin and male fetal lung fibroblasts, while FMR2 transcripts were not. However, both FMR1 and FMR2 were found to replicate late in S phase (approximately 6 h into the S phase of normal human fibroblasts). The position of the origin of replication relative to the CGG repeat, and perhaps the late replication of these genes, might be important factors in the susceptibility to triplet repeat amplification at the FRAXA and FRAXE sites.
