Abstract
PURPOSE To analyze the copy number variation (CNV) in the X-linked genes BCORL1, POF1B, and USP9X in idiopathic diminished ovarian reserve (DOR). METHODS This case-control study included 47 women, 26 with DOR and 21 in the control group. Age, weight, height, BMI, and FSH level were evaluated, as well as antral follicle count (AFC), oocyte retrieval after controlled ovarian stimulation, and metaphase II (MII) oocytes. The CNVs of BCORL1, USP9X, and POF1B genes were measured by quantitative real time PCR (qPCR) using two reference genes, the HPRT1 (X-linked) and MFN2 (autosomal). Protein-protein interaction network and functional enrichment analysis were performed using the STRING database. RESULTS The mean age was 36.52 ± 4.75 in DOR women and 35.38 ± 4.14 in control. Anthropometric measures did not differ between the DOR and control groups. DOR women presented higher FSH (p = 0.0025) and lower AFC (p < .0001), oocyte retrieval after COS (p = 0.0004), and MII oocytes (p < .0001) when compared to the control group. BCORL1 and POF1B did not differ in copy number between DOR and control. However, DOR women had more copies of USP9X than the control group (p = 0.028). CONCLUSION The increase in the number of copies of the USP9X gene may lead to overexpression in idiopathic DOR and contribute to altered folliculogenesis and oocyte retrieval.

Abstract
Evolutionary and comparative approaches can yield novel insights into human adaptation and disease. Endometriosis and polycystic ovary syndrome (PCOS) each affect up to 10% of women and significantly reduce the health, fertility, and quality of life of those affected. PCOS and endometriosis have yet to be considered as related to one another, although both conditions involve alterations to prenatal testosterone levels and atypical functioning of the hypothalamic-pituitary-gonadal (HPG) axis. Here, we propose and evaluate the novel hypothesis that endometriosis and PCOS represent extreme and diametric (opposite) outcomes of variation in HPG axis development and activity, with endometriosis mediated in notable part by low prenatal and postnatal testosterone, while PCOS is mediated by high prenatal testosterone. This diametric disorder hypothesis predicts that, for characteristics shaped by the HPG axis, including hormonal profiles, reproductive physiology, life-history traits, and body morphology, women with PCOS and women with endometriosis will manifest opposite phenotypes. To evaluate these predictions, we review and synthesize existing evidence from developmental biology, endocrinology, physiology, life history, and epidemiology. The hypothesis of diametric phenotypes between endometriosis and PCOS is strongly supported across these diverse fields of research. Furthermore, the contrasts between endometriosis and PCOS in humans parallel differences among nonhuman animals in effects of low versus high prenatal testosterone on female reproductive traits. These findings suggest that PCOS and endometriosis represent maladaptive extremes of both female life-history variation and expression of sexually dimorphic female reproductive traits. The diametric disorder hypothesis for endometriosis and PCOS provides novel, unifying, proximate, and evolutionary explanations for endometriosis risk, synthesizes diverse lines of research concerning the two most common female reproductive disorders, and generates future avenues of research for improving the quality of life and health of women.

[PMID: 34068234 PMCID: PMC8153136 DOI: 10.3390/jcm10102101] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2021] [Revised: 05/09/2021] [Accepted: 05/10/2021] [Indexed: 01/21/2023] Open
Abstract
The knowledge of polycystic ovary syndrome (PCOS) natural history is limited. Our objective was to assess the effect of aging on clinical, hormonal and sonographic ovarian PCOS features and additionally to identify parameters that impact the course of PCOS. A secondary aim was to supply additional information on the reproductive outcome in women with previously diagnosed PCOS. A longitudinal cohort study with a median follow-up of 120.9 months was conducted, and 31 Caucasian women previously diagnosed with PCOS according to the Rotterdam criteria were re-examined at a median age of 35. Clinical examinations; transvaginal ultrasound scans; and lipid, E-selectin and sex hormone assessments were performed at the beginning and at the end of the follow-up. It was observed that menstrual cycles became regular and sonographic morphology of ovaries was normalized in 55% and 49% of the participants, respectively (all p < 0.05). At the final assessment, 55% of the women no longer met the criteria for PCOS (p < 0.05). The age, follicle-stimulating hormone (FSH) and E-selectin assessed at the baseline were the most important predictors of the PCOS persistence into later years (respectively, OR = 0.84, OR = 0.39, OR = 1.08, all p < 0.05). Ninety-five percent of the patients who had ever been trying to conceive became pregnant a minimum of once. The women with persistent PCOS had worse metabolic and reproductive parameters compared to the women with resolved PCOS. Positive correlations were found between the number of miscarriages and ovarian volume, LH, androstenedione, 17-hydroxyprogesterone and an increase in E-selectin during the follow-up (R = 0.46, R = 0.59, R = 0.54, R = 0.49, R = 0.47, all p < 0.05). In conclusion, progressing from the third to the fourth decade is connected with a reduction in PCOS features, which seems to have a great impact on fertility of women with a previous diagnosis of PCOS. FSH and E-selectin, as determined at the initial PCOS diagnosis, had an impact on the disappearance of the syndrome years after.

Abstract
OBJECTIVE To analyse whether sex hormone replacement therapy (HRT) improves periodontal parameters and dental implants osseointegration in humans. MATERIALS AND METHODS Electronic databases and hand searches were performed from June to August 2018 in SciELO, LILACS and PubMed/MEDLINE. Human observational and interventional studies that evaluated the following parameters were included: clinical attachment loss (CAL), probing pocket depth (PPD), bleeding on probing (BOP), radiographic bone loss (RBL) or osseointegration. RESULTS Initial search retrieved 1,282 non-duplicated articles. Fifteen studies were selected after inclusion criteria were applied. All studies were performed in postmenopausal women. Mean differences for PPD reduction ranged from 0.02 to 0.2 mm in HRT-positive patients; mean CAL gain -0.18 to 0.54 mm; mean RBL reduction -0.87 to 0.15 mm; and mean BOP reduction 9%-30.3%. Failure rate of dental implants increased -5.5% to 11.21% when HRT was used. CONCLUSIONS Very low but consistent evidence suggests a reduction in BOP and no impact on RBL in postmenopausal women receiving HRT. There are inconsistent reports that suggest that HRT in postmenopausal women: (a) improves or does not impact PPD reduction and CAL gain; and (b) does not impact or increase implant loss. In summary, there is no evidence to support HRT prescription for either men or women for periodontal/implant placement purposes.

Abstract
PURPOSE Follicle-stimulating hormone (FSH) and its receptor play a major role in the development of follicles and regulation of steroidogenesis in the ovary and spermatogenesis in the testis. We aim to analyze the role of FSHR gene variants (single nucleotide polymorphisms (SNPs) in exon 10 (codon 307 and 680) and in the core promoter region (at position -29) and Ala189Val inactivating mutation) in Turkish infertile women. There were studies analyzing the effects of the SNPs in exon 10 (codon 307 and 680) and in the core promoter region (at position -29) of the FSHR gene on spermatogenesis, but to our knowledge, there were no studies analyzing the effects of these three SNP combinations on female fertility. METHODS In this study, the allelic, genotype, and haplotype frequency distributions of these three SNPs in the FSHR gene were analyzed in 102 infertile women and 99 unrelated healthy control individuals. The distribution of the polymorphisms was conformed by Hardy-Weinberg equilibrium test. RESULTS There were no statistical differences (P > 0.05) in the allele, genotype, and haplotype frequencies of the polymorphisms and FSH, luteinizing hormone (LH), estradiol (E2), and prolactin (PRL) levels between the infertile patients and the controls. However, a significant relation was found between 307 SNP GA genotype and FSH level ≥12. We did not find any homozygous or heterozygote mutations in infertile patients and healthy fertile controls. CONCLUSION The present study was the first study analyzing gma mutation and the polymorphism of the FSHR core promoter at position -29 alone and in combination with the two common SNPs in exon 10 in Turkish infertile women population. These findings indicate the significance of Ala307Thr GA genotype may be a predictive marker for poor ovarian reserve and infertility.

Abstract
INTRODUCTION Cyclophosphamide (CPA) chemotherapy leads to ovarian failure and infertility. Tocotrienol (T3) is an antioxidant and anti-inflammatory agent. The role of T3 in ovarian protection throughout chemotherapy remains unclear. AIM To investigate the role of T3 in the preservation of female fertility in CPA treatment. METHOD Sixty female mice were divided into five treatment groups, namely, normal saline, corn oil only, T3 only, CPA and CPA + T3. The treatment was given for 30 days, followed by administration of gonadotrophin to induce ovulation. After killing, both ovaries were collected and examined histologically. RESULTS There was significant reduction in ovarian size in the CPA group compared with the normal group (CPA versus normal, mean area ± SD; 0.118 ± 0.018 vs. 0.423 ± 0.024 cm(2); p ≤ 0.005), whilst concurrent administration of T3 with CPA leads to conservation of ovarian size (CPA + T3 vs. CPA, mean area ± SD; 0.285 ± 0.032 vs. 0.118 ± 0.018 cm(2); p ≤ 0.005). Ovaries in CPA group showed abnormal folliculogenesis with accompanied reduced ovulation rate, follicular oedema, increased vascularity and inflammatory cell infiltration. These changes were reversed by concurrent T3 administration. CONCLUSION Co-administration of T3 with CPA confers protection of ovarian morphology and function in vivo. These findings contribute to the further elucidation of CPA effect on ovary and suggest the potential of T3 use in preserving fertility in chemotherapy.

Abstract
The Polycystic Ovary Syndrome (PCOS) is a complex endocrine disorder characterised both by reproductive and metabolic disturbance, and is the most common cause globally of ovarian infertility. It is also a familial polygenic condition, linked genetically to both Type 2 diabetes and the metabolic syndrome. The striking evolutionary paradox of this prominent genetically-based condition, which impairs fertility, is that not only should it have diminished in prevalence, but it should have done so rapidly - unless there has been some form of balancing selection. The emerging discipline of evolutionary medicine can provide important insights into the causes and patterns of occurrence of common diseases such as PCOS. In this paper we review the impacts of PCOS on infertility, fecundability and lifetime reproductive success and then critically appraise published hypotheses about the evolutionary origins of PCOS and related conditions.

Abstract
CONTEXT Previous studies have suggested that antimüllerian hormone (AMH) levels are positively associated with in vitro fertilization (IVF) outcome through their relationship with oocyte yield and not by reflecting oocyte or embryo quality. OBJECTIVE The aim was to investigate whether AMH levels are associated with pregnancy and live-birth rates and whether the results may also reflect qualitative aspects of oocytes and embryos. DESIGN The study was a prospective cohort study between April 2008 and June 2011. SETTING The study was done at a university-affiliated private infertility center. PATIENTS The study cohort consisted of 892 consecutive women undergoing 1230 IVF-intracytoplasmic sperm injection cycles. INTERVENTION(S) AMH levels, analyzed using the DSL ELISA kit, were statistically adjusted for repeated treatments and age and analyzed for associations with treatment outcome. MAIN OUTCOME MEASURES Pregnancy rates, live-birth rates, and stimulation outcome parameters were measured. RESULTS AMH was log-normally distributed with a mean (SD) of 2.3 (2.5) ng/mL. Live-birth rates per started cycle (mean [95% confidence interval]) increased log-linearly from 10.7% [7.2-14.1] for AMH < 0.84 ng/mL (25th percentile) to 30.8% [25.7-36.0] for AMH > 2.94 ng/mL (75th percentile), Ptrend < .0001, being superior in women with polycystic ovaries. These findings were significant also after adjustments were made for age and oocyte yield. AMH was also associated with ovarian response variables and embryo scores. CONCLUSIONS AMH is strongly associated with live-birth rates after IVF-intracytoplasmic sperm injection. AMH may therefore serve as a prognostic factor for the chance of a pregnancy and live birth. Treatment outcome was superior in patients with polycystic ovaries. The findings also indicate that AMH may partially comprise information about oocyte quality.

Abstract
Although in the UK the upper age limit for National Health Service (NHS) provision of in vitro fertilisation (IVF) is 39 years of age there has been an increase in number of women having fertility treatment in their 40s. However, the success rates of IVF and intra-uterine insemination (IUI) in this group remain low. Human Fertilisation and Embryology Authority (HFEA) data from 2006 showed that the live-birth rate from IVF in the UK was 11% in the age group 40-42, 4.6% in the age group 43-44 and less than 4% in women over 44. We performed a literature search for studies using terms and combinations of terms in online databases and published meta-analyses reporting the outcome of interventions in older women. This review showed that assisted reproduction technologies (ARTs) continue to have low live-birth rates in women over 40. Trials showed that assisted hatching may increase the chance of pregnancy in women with poor history. Blastocyst transfer is associated with better outcome, whereas application of pre-implantation genetic screening (PGS) in older women has not increased the success rates. It appears that, with the exception of egg-donation, ART has no answer yet to age-related decline of female fertility.

Abstract
The objective of this study was to determine whether there was a threshold for the number of CGG repeats in the FMR1 (fragile X) gene in premature ovarian ageing and premature ovarian failure and to investigate the association of this sequence with serum concentrations of anti-Müllerian hormone (AMH), inhibin B, anti-thyroid and anti-adrenal autoantibodies. In this prospective randomized controlled preliminary study, the number of triple CGG repeats and serum concentrations of FSH, AMH and aforementioned autoantibodies were evaluated in 79 women who were younger than 40 years old. FSH concentrations were between 12 and 50 IU/ml (premature ovarian ageing) in 30 women and were higher than 50 IU/ml (premature ovarian failure) in nine women; FSH concentrations were normal in 40 women. All women whose FSH concentrations were higher than 12 IU/ml had CGG repeats greater than 30. No women whose FSH concentrations were normal had a repeat number above 30. There was no significant relationship between the levels of antibodies and either CGG repeat numbers or FSH concentrations. In conclusion, the number of CGG repeats between 30 and 40 might be used to predict premature ovarian ageing and premature ovarian failure in infertile women.

METHODS Three hundred twenty-eight women (40 to 69 years old) who participated in a previous oral survey in South Brazil were included. Women who reported not having their monthly menstrual cycles for >or=12 months were classified as postmenopausal. Postmenopausal women were categorized according to HRT. Women with >or=30% teeth with PAL >or=5 mm were classified as having periodontitis. The data were analyzed using a multivariable logistic regression model and adjusted for age, smoking, socioeconomic status, and dental care. RESULTS The prevalence of periodontitis was significantly greater among postmenopausal women not using HRT (HRT-) than among premenopausal women (64.4% versus 46.3%; P = 0.005). Similarly, the multivariable analysis demonstrated a significantly higher chance of having periodontitis in postmenopausal HRT- women than in premenopausal women (odds ratio [OR], 2.1; 95% confidence interval [CI]: 1.1 to 4.0). In contrast, no significant differences were observed in the prevalence of periodontitis between postmenopausal women using HRT (HRT+) and premenopausal women (48.8% versus 46.3%; P = 0.77). After adjusting for cofactors, postmenopausal HRT+ women did not have a greater likelihood of having periodontitis than premenopausal women (OR, 1.2; 95% CI: 0.6 to 2.5). No significant differences in tooth loss were observed among the study groups after adjusting for confounders. CONCLUSIONS Postmenopausal HRT- women had a greater chance of having periodontitis than premenopausal women. In contrast, postmenopausal HRT+ women and premenopausal women had similar periodontal status. HRT may have a beneficial effect on periodontal health.

Abstract
PURPOSE OF REVIEW It is estimated that 10% of women experience a rapid decline in their ovarian reserve from the early 30s. This is called 'early ovarian ageing'. With the development of the so-called 'ovarian reserve tests', it was hoped that it would be possible to assess each woman's ovarian biological age and screen for 'early ovarian ageing' in the general population. This review examines the progress that has been made in this area. RECENT FINDINGS Almost the entire literature on ovarian reserve tests refers to women having IVF, rather than women in the general population. Recent systematic reviews have shown that the currently known 'ovarian reserve' tests are reasonably good at predicting the number of eggs that are collected following ovarian stimulation with gonadotrophins in the context of an IVF cycle. They show very poor correlation with live-birth rates. The reason is that they cannot directly assess oocyte quality. SUMMARY Screening for 'early ovarian ageing' in the general population is desirable but still not possible. Therefore, postponing childbearing to the late 30s remains a risky gamble. Advice to individual women should be given by specialist reproductive endocrinologists, though home-testing is not advisable.

Abstract
BACKGROUND The purpose of the present study was to examine long-term reproductive outcome and ovarian reserve in an unselected population of women with polycystic ovary syndrome (PCOS). METHODS A total of 91 patients with confirmed PCOS and 87 healthy controls were included in the study. Patients had been diagnosed between 1987 and 1995 and at the time of the follow-up, subjects were 35 years of age or older. RESULTS Among women who had attempted a pregnancy, 86.7% of PCOS patients and 91.6% of controls had given birth to at least one child. Among PCOS patients who had given birth, 73.6% had done so following a spontaneous conception. Mean ovarian volume and the number of antral follicles in PCOS patients were significantly greater than in control women (P < 0.001, respectively). PCOS patients also had higher serum concentrations of anti-Müllerian hormone and lower follicle-stimulating hormone levels. CONCLUSIONS Most women with PCOS had given birth, and the rate of spontaneous pregnancies was relatively high. Together with the ultrasound findings and the hormonal analyses, this finding could imply that PCOS patients have a good fecundity, and an ovarian reserve possibly superior to women with normal ovaries.

Abstract
OBJECTIVE To assess whether abnormal autoimmune function and number of triple CGG repeats on the FMR1 (fragile X) gene, both historically associated with risk toward premature ovarian senescence, represent independent risk factors. DESIGN Retrospective cohort study. SETTING Academically affiliated, private fertility center. PATIENT(S) Forty consecutive, new infertility patients, of which 11 presented with a primary diagnosis of repeat pregnancy loss, 23 with prematurely elevated, age-specific baseline follicle stimulating hormone (FSH) levels (i.e., premature ovarian aging) and 6 with premature ovarian failure. INTERVENTION(S) Determination of triple CGG repeats on both alleles of the FMR1 gene, assessment of ovarian reserve via FSH and anti-Müllerian hormone levels, and evaluation of autoimmune status by antiphospholipid antibody panel, antinuclear antibody panel, total immunoglobulin levels (IgG, IgM, IgA), thyroid antibodies (antiglobulin and antimicrosomal), antiovarian, and antiadrenal antibodies. RESULT(S) Twenty-two of 40 patients (55%) demonstrated autoimmune abnormalities. Women with and without autoimmune abnormalities did not differ in age. Patients with autoimmune abnormalities, however, demonstrated significantly lower FSH levels and higher anti-Mullerian hormone levels. Although triple repeats on the lower count allele (allele-1) of the FMR1 gene did not differ statistically, autoimmune patients demonstrated in the higher count allele (allele-2) significantly fewer triple repeats, significantly fewer triple repeats >or=30, and, in contrast to nonautoimmune patients, a normal mean level of triple repeats. CONCLUSION(S) Abnormal autoimmune function and expansions in triple CGG repeats on the FMR1 gene represent distinctively different etiologies for premature ovarian senescence in infertile patients and may, indeed, constitute its two principal causes.

Abstract
Polycystic ovarian syndrome (PCOS) is universally recognised as the commonest endocrinopathy of women. The definition and the aetiological hypotheses of PCOS are continuously evolving to accommodate expanding knowledge on the syndrome, which is now known to be more complex than purely a reproductive disorder. Increased androgen synthesis, disrupted folliculogenesis and insulin resistance lie at the pathophysiological core of PCOS. An intriguing concept involves the perpetuation of a vicious circle with endocrine/reproductive and metabolic components. An unfavourable metabolic environment may unmask genetic traits of ovarian dysfunction, and the unfolding endocrine derangement could further aggravate the metabolic disarray. This article reviews the molecular mechanisms known to underlie the ovarian and metabolic abnormalities characterising PCOS. The putative interdependence between reproductive and metabolic aspects of PCOS, and therapeutic implications for the management of PCOS, are also discussed.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a frequent cause of infertility. Despite an impressive number of reports, few have evaluated the influence of age upon fertility. We present the outcomes of three infertile women with PCOS who achieved spontaneous pregnancies when ageing. CASE REPORTS Three patients with PCOS were monitored for more than 20 years. PCOS was confirmed by clinical data (oligo/amenorrhoea, infertility, hirsutism), hormonal measures and ovarian ultrasonography. All three infertile patients were treated for several years using numerous ovulation induction protocols with varying responses. When ageing, they gained more regular cycles and spontaneously became pregnant at 39, 40 1/2 and 36 years of age, more than 5 years after induction treatment was stopped, and in spite of increasing weight in each of them. CONCLUSIONS These clinical observations suggest improved fertility in some PCOS ageing women. The positive impact of ageing on cycle regularisation in PCOS has recently been claimed but the fertility outcome was not evaluated. Ovary ageing results in diminution of the follicular cohort in both normal and PCOS women, associated with decreased inhibin B and anti-müllerian hormone (AMH) levels. Lower inhibin B levels induce FSH enhancement, with a rise in FSH rate per follicle which may determine better follicle maturation, regular and ovulatory cycles in PCOS ageing women. The best proof of this improved fertility was the occurrence of spontaneous pregnancies which never occurred previously.

Abstract
The 'ESHRE/ASRM consensus on diagnosis, nomenclature and long-term health risks of polycystic ovarian syndrome (PCOS)' (conference in Rotterdam, Netherlands, March, 2003), which was criticized shortly after its oral presentation in 2003, is still being debated following its publication in 2004. Therefore, an extended, intensive analysis of all parameters and their combinations has been performed, differentiating between inclusion and exclusion criteria. By doing this, the profound significance of the endocrinological part of the syndrome is highlighted. The nomenclature, semantic meaning of terms, definitions, structural balancing, specificity, practicability, flexibility, limitations and reproducibility for both individualization, as well as grouping from the clinical and scientific perspective, have been examined in detail. This analysis supports previous critical comments, and reaches the conclusion that the recommendations of the consensus lack accuracy and specificity, a weakness that results in the risk of overdiagnosis and in a lack of reproducibility. Altogether, they fail to fulfil the criteria of universal guidelines on several levels. Instead, a profound paradigm shift is demanded, from an inconsistent perception to a more systematic, balanced and comprehensive view. A short indication on an alternative sweeping concept of a strictly defined, therapy-targeted classification and diagnostic procedure of female functional androgenization is presented.

Abstract
Polycystic ovarian disease (PCOD) is currently considered as possibly the most frequent cause of female infertility. It is also closely associated with syndrome XX, which, in turn, is closely linked with premature and excessive mortality. Considering these adverse effects on reproductive success and human survival, the evolutionary survival of PCOD, itself considered by many to be a genetically transmitted condition, would, on first glance, appear surprising, since evolution usually discriminates against both of these traits. However, an analysis of some recently reported characteristics of the condition calls for the reconsideration of PCOD as a condition which, from an evolutionary viewpoint, favours decreased reproductive success. Indeed, the reported observations that patients with PCOD will resume spontaneous ovulation with even relatively minor weight loss, and experience later menopause than controls, suggests exactly the opposite. Under an evolutionary concept, PCOD can thus be seen as a 'fertility storage condition' which in fact favours human reproductive success and allows the human species to maintain fertility even during adverse environmental circumstances, such as famines.

Abstract
AIM The present study aimed to establish inhibin A and B serum levels during the menstrual cycle of obese women, and its usefulness as an index of luteal-phase follicular development. MATERIALS AND METHODS Twenty-one obese patients (mean body mass index: 34.9+/-3.7 kg/m2; range: 30.0-45.0 kg/m2) were submitted to basal hormonal measurements and an oral glucose tolerance test after challenge with 75 g glucose. Progesterone and inhibin A and B levels were determined 5-7 days after the menstrual cycle and 7 days prior to expected menses. RESULTS As expected, an increase in inhibin A and a decrease in inhibin B were observed when first-phase samples were compared with samples obtained after 15-20 days. On the other hand, the percentage variation of both inhibin A and B was at least four times smaller than the values for normal women described previously by other authors employing the same enzyme-linked immunosorbent assays. A small number of obese women presented ovulatory cycles characterized by progesterone concentration higher than 5.8 ng/ml. The percentage elevation (>190%) of inhibin A in the second samples was in agreement with the progesterone levels, but it seemed to be more sensitive for the detection of follicle luteinization. CONCLUSION We conclude that obese women present less percentage variation of both inhibin A and B during the menstrual cycle, associated with a low frequency of ovulatory cycles. In obese women, the percentage increase of inhibin A can represent an additional marker to recognize follicle luteinization.
