Abstract
Background The average age of childbearing has increased over the years contributing to infertility, miscarriages, and chromosomal abnormalities largely invoked by an age-related decline in oocyte quality. In this study, we investigate the role of nitric oxide (NO) insufficiency and protein nitration in oocyte chronological aging. Methods Mouse oocytes were retrieved from young breeders (YB, 8-14 weeks [w]), retired breeders (RB, 48-52w) and old animals (OA, 80-84w) at 13.5 and 17 hours after ovulation trigger. They were assessed for zona pellucida dissolution time (ZPDT); ooplasmic microtubule dynamics (OMD); cortical granule (CG) status and spindle morphology (SM), as markers of oocyte quality. Sibling oocytes from RB were exposed to NO supplementation and assessed for aging phenomena (AP). All oocyte cumulus complexes were subjected to fluorescence nitrotyrosine (NT) immunocytochemistry and confocal microscopy to assess morphology and protein nitration. Results At 13.5 h from hCG trigger, oocytes from RB compared to YB had significantly increased ZPDT (37.8 ± 11.9 vs 22.1 ± 4.1 seconds [s]), OMD (46.9 vs 0%), CG loss (39.4 vs 0%), and decreased normal SM (30.3 vs 81.3%), indicating premature AP that worsened among oocytes from RB at 17 hours post-hCG trigger. When exposed to SNAP, RB AP significantly decreased (ZPDT: 35.1 ± 5.5 vs 46.3 ± 8.9s, OMD: 13.3 vs 75.0% and CG loss: 50.0 vs 93.3%) and SM improved (80.0 vs 14.3%). The incidence of NT positivity was significantly higher in cumulus cells (13.5 h, 46.7 ± 4.5 vs 3.4 ± 0.7%; 17 h, 82.2 ± 2.9 vs 23.3 ± 3.6%) and oocytes (13.5 h, 57.1 vs 0%; 17 h, 100.0 vs 55.5%) from RB compared to YB. Oocytes retrieved decreased with advancing age (29.8 ± 4.1 per animal in the YB group compared to 10.2 ± 2.1 in RB and 4.0 ± 1.6 in OA). Oocytes from OA displayed increased ZPDT, major CG loss, increased OMD and spindle abnormalities, as well as pronuclear formation, confirming spontaneous meiosis to interphase transition. Conclusions Oocytes undergo zona pellucida hardening, altered spindle and ooplasmic microtubules, and premature cortical granule release, indicative of spontaneous meiosis-interphase transition, as a function of chronological aging. These changes are also associated with NO insufficiency and protein nitration and may be alleviated through supplementation with an NO-donor.

Abstract
Purpose The current definition of menstrual cycle length in a Japanese woman is different from those of WHO definition, and the original data are outdated. We aimed to calculate the distribution of follicular and luteal phases length in modern Japanese women with various menstrual cycles. Methods This study determined the lengths of the follicular and luteal phases of Japanese women using basal body temperature data collected via a smartphone application from 2015 to 2019, and the data were analyzed using the Sensiplan method. Over 9 million temperature readings from more than 80 000 participants were analyzed. Results The mean duration of the low-temperature (follicular) phase averaged 17.1 days and was shorter among participants aged 40-49 years. The mean duration of the high-temperature (luteal) phase was 11.8 days. The variance and maximum-minimum difference of the length of the low temperature period were significant in women under 35 years old than women aged more than 35 years. Conclusions The shortening of the follicular phase in women aged 40-49 years implied a relationship with the rapid decline of ovarian reserve in these women, and the age 35 years old was turning point of ovulatory function.

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

Abstract
Ovarian ectopic pregnancy (OEP) represents the rarest type of ectopic pregnancy, accounting for 1–3% of this pathology. The diagnosis of this pathology is challenging due to the non-specific clinical aspects and the ultrasound examination hampered by the lack of visible gestational sac in the presence of hematocele and hemoperitoneum. The purpose of the extended histopathological (HP) examination was to identify particular aspects of the OEP trophoblast and to highlight potential local ovarian modifications which can determine pregnancy fixation at this level. The patient presented local favorable conditions for intraovarian nidation, conditions confirmed by the HP classical examination and by the immunohistochemical evaluation. We identified, using classical Hematoxylin–Eosin, Masson’s trichrome and Periodic Acid–Schiff (PAS)–Hematoxylin, necrotic hemorrhage, accentuated vascular thrombosis and high density lymphoplasmocytary infiltrate. These modifications increased local adhesivity and cell destruction through hypoperfusion. Anti-cluster of differentiation antibodies (CD34, CD38, tryptase) revealed the low number of intravillous vessels and the high number of macrophages and mastocytes involved in the local inflammatory process heighten. We identified the presence of trophoblast tissue in the ovarian structure using anti-cytokeratin AE1/AE3 (CK AE1/AE3)/anti-cytokeratin 7 (CK7) antibodies. The anti-alpha-smooth muscle actin (α-SMA) and anti-vimentin (VIM) antibodies displayed the density of myofibroblasts and intravillous stromal cells and with the aid of anti-progesterone receptor (PR) antibody, we identified the corpus luteum hormonal response in the OEP. The placental villosities present a blocked multiplication process at the anti-apoptotic B-cell lymphoma 2 (BCL2) protein, confirmed by the Ki67 cell proliferation and tumor protein 63 (p63) immunomarkers. Anti-neuron specific enolase (NSE), anti-calretinin and anti-inhibin A antibodies showed the particular aspects of the granulosa and internal theca cells, which may be involved in oocyte release blockage, intraluteal and extraluteal fecundation of the OEP.

Abstract
Anti-Müllerian hormone (AMH) and inhibin B are considered possible biomarkers of central precocious puberty (CPP). The aim of this study was to evaluate serum levels of AMH and inhibin B, to investigate their regulatory patterns, and to study their clinical significance in girls with CPP. In total, 48 girls with CPP and 35 age-matched prepubertal control girls were enrolled in the study. AMH and inhibin B levels were determined in the CPP and control groups. In the patient group, AMH and inhibin B levels were evaluated during 1 year of gonadotropin releasing hormone analog (GnRHa) treatment. The mean inhibin B level in the CPP group was significantly higher than that in the control. AMH levels were not different between the two groups. After GnRHa treatment. AMH and inhibin B levels decreased significantly. Based on the ROC analysis, the cutoff value for inhibin B to determine CPP was 19.59 pg/mL, with 83.3% sensitivity and 82.9% specificity, and the area under the curve was 0. 852. Inhibin B was useful for determining CPP and the therapeutic effects of GnRHa treatment in girls with CPP. AMH interacted, in part, with the hypothalamo-pituitary gonadal axis, but its clinical implications in CPP should be further investigated.

Abstract
In the prenatal quad screen, the levels of four analytes in maternal serum are used to calculate the risk of serious birth defects. The Beckman Access2 Immunoassay System is an automated analyzer that enables rapid measurement of alpha-fetoprotein, unconjugated estriol, human chorionic gonadotropin, and dimeric inhibin A. The Benetech PRA software package is used to convert maternal serum analyte concentrations to multiples of the median (MoM) and calculates the risks of particular birth defects. The results from this simple and minimally invasive screen determine the need for more sensitive, specific, and usually riskier diagnostic procedures. We present herein some recent data from our experience at Columbia University Medical Center in New York, NY, using the Beckman Access2 immunoassay analyzer and Benetech PRA software package.

Abstract
Objective This retrospective study was conducted to explore causes of unsynchronized follicular maturation (UFM) and analyze the effects of large follicle puncture on embryo quality and pregnancy outcome. Methods Clinical features and controlled ovulation hyperstimulation (COH) were compared between the puncture group (n = 48) and the control group (n = 2545). We analyzed the COH process with in vitro fertilization during fresh cycle embryo transfer with different clinical pregnancy outcomes. We compared clinical characteristics and COH process of patients in the clinical pregnancy (n = 774) and non-clinical pregnancy (n = 527) groups. Finally, factors related to pregnancy outcomes were analyzed using multivariate logistic regression analysis. Results Age, level of estradiol on down-regulation day, and initial gonadotropin dose were significantly higher in the puncture group than in the control group. We detected significant differences in age, infertility, and body mass index (BMI) between the clinical and non-clinical pregnancy groups. Age, BMI, and endometrial thickness on the day of human chorionic gonadotropin administration were the independent factors influencing pregnancy outcome. Conclusions Patient’s age and level of anti-Müllerian hormone were the main factors causing UFM in patients undergoing COH. Large follicle puncture had no significant effect on pregnancy outcome.

Abstract
Bone loss in women accelerates during perimenopause, and continues into old age. To-date, there has been little progress made in stratifying for fracture risk in premenopausal and early postmenopausal women. Epidemiologic data suggests that changes in serum FSH could predict decrements in bone mass during peri- and postmenopause. In bone, FSH stimulates osteoclast formation by releasing osteoclastogenic cytokines. Here, we address the evidence for bone loss across the menopausal transition, discuss strategies for detection and treatment of early postmenopausal osteoporosis, and describe the role FSH plays in physiology and likely in pathophysiology of early postmenopausal bone loss.

Abstract
Women of advanced maternal age (AMA) (age ≥ 35) have increased rates of infertility, miscarriages, and trisomic pregnancies. Collectively these conditions are called "egg infertility." A root cause of egg infertility is increased rates of oocyte aneuploidy with age. AMA women often have elevated endogenous FSH. Female senescence-accelerated mouse-prone-8 (SAMP8) has increased rates of oocyte spindle aberrations, diminished fertility, and rising endogenous FSH with age. We hypothesize that elevated FSH during the oocyte's FSH-responsive growth period is a cause of abnormalities in the meiotic spindle. We report that eggs from SAMP8 mice treated with equine chorionic gonadotropin (eCG) for the period of oocyte growth have increased chromosome and spindle misalignments. Activin is a molecule that raises FSH, and ActRIIB:Fc is an activin decoy receptor that binds and sequesters activin. We report that ActRIIB:Fc treatment of midlife SAMP8 mice for the duration of oocyte growth lowers FSH, prevents egg chromosome and spindle misalignments, and increases litter sizes. AMA patients can also have poor responsiveness to FSH stimulation. We report that although eCG lowers yields of viable oocytes, ActRIIB:Fc increases yields of viable oocytes. ActRIIB:Fc and eCG cotreatment markedly reduces yields of viable oocytes. These data are consistent with the hypothesis that elevated FSH contributes to egg aneuploidy, declining fertility, and poor ovarian response and that ActRIIB:Fc can prevent egg aneuploidy, increase fertility, and improve ovarian response. Future studies will continue to examine whether ActRIIB:Fc works via FSH and/or other pathways and whether ActRIIB:Fc can prevent aneuploidy, increase fertility, and improve stimulation responsiveness in AMA women.

Abstract
Inhibins, as members of the transforming growth factor beta (TGF-β)
superfamily, downregulate the synthesis and secretion of follicle-stimulating hormone
(FSH) in an endocrine manner. The role of inhibin/betaglycan in the ovary regulation
recently gained attention. To date, no data exist on the function of inhibin α subunit and
betaglycan in cystic follicles. In this study, the expressions of inhibin α subunit and
betaglycan in cystic follicles were investigated using immunohistochemistry, real-time PCR
and Western blot analysis. Both inhibin α subunit and betaglycan immunoreactivities were
mainly localized in the granulosa cells of follicles. Expression of inhibin α subunit and
betaglycan was inferior in cystic follicles compared with that in normal large follicles.
However, the result of enzyme-linked immunosorbent assay showed no significant difference
in the decreasing in concentration of inhibin α subunit in cystic follicular fluid
compared with the control (P>0.05). In this study, we explored the
effects of FSH on betaglycan expression in granulosa cells in vitro. As
expected, a significant increase in the expressions of betaglycan mRNA and protein in
granulosa cells was observed in response to exogenous FSH (30
ng/ml) (P<0.05) compared with the
control. Consequently, this study provides evidence that the expressions of inhibin α
subunit and betaglycan are inferior in cystic follicles, and this may be caused by the
decrease in FSH in the presence of a cystic follicle.

Abstract
BACKGROUND Aim of the study was to investigate whether menstrual cycle length may be considered as a surrogate measure of reproductive health, improving the accuracy of biochemical/sonographical ovarian reserve test in estimating the reproductive chances of women referred to ART. METHODS A retrospective-observational-study in Padua' public tertiary level Centre was conducted. A total of 455 normo-ovulatory infertile women scheduled for their first fresh non-donor IVF/ICSI treatment. The mean menstrual cycle length (MCL) during the preceding 6 months was calculated by physicians on the basis of information contained in our electronic database (first day of menstrual cycle collected every month by telephonic communication by single patients). We evaluated the relations between MCL, ovarian response to stimulation protocol, oocytes fertilization ratio, ovarian sensitivity index (OSI) and pregnancy rate in different cohorts of patients according to the class of age and the estimated ovarian reserve. RESULTS In women younger than 35 years, MCL over 31 days may be associated with an increased risk of OHSS and with a good OSI. In women older than 35 years, and particularly than 40 years, MCL shortening may be considered as a marker of ovarian aging and may be associated with poor ovarian response, low OSI and reduced fertilization rate. When AMH serum value is lower than 1.1 ng/ml in patients older than 40 years, MCL may help Clinicians discriminate real from expected poor responders. Considering the pool of normoresponders, MCL was not correlated with pregnancy rate while a positive association was found with patients' age. CONCLUSIONS MCL diary is more predictive than chronological age in estimating ovarian biological age and response to COH and it is more predictive than AMH in discriminating expected from real poor responders. In women older than 35 years MCL shortening may be considered as a marker of ovarian aging while chronological age remains most accurate parameter in predicting pregnancy.

Abstract
Background: Studies reveal that lifestyles such as physical activity patterns, obesity, nutrition, and smoking, are factors that affect laboratory test results and pregnancy outcomes induced by assisted fertility techniques in infertile couples. The present study is a narrative review of studies in this area. Methods: In this study, researchers conducted their computer search in public databases Google Scholar general search engine, and then more specific: Science Direct, ProQuest, SID, Magiran, Irandoc, Pubmed, Scopus, cochrane library, and Psych info; Cumulative Index to Nursing and Allied Health Literature (CINAHL), using Medical Subject Headings (MeSH) keywords: infertility (sterility, infertility), lifestyle (life behavior, lifestyle), Assisted Reproductive Techniques (ART), antioxidant and infertility, social health, spiritual health, mental health, Alcohol and drug abuse, preventive factors, and instruments., and selected relevant articles to the study subject from 2004 to 2013. Firstly, a list of 150 papers generated from the initial search. Then reviewers studied titles and abstracts. Secondly, 111 papers were included. Finally, quality assessment of full text studies was performed by two independent reviewers. Researchers reviewed summary of all articles sought, ultimately used data from 62 full articles to compile this review paper. Results: Review of literature led to arrangement of 9 general categories of ART results’ relationship with weight watch and diet, exercise and physical activity, psychological health, avoiding medications, alcohol and drugs, preventing diseases, environmental health, spiritual health, social health, and physical health. Conclusion: The following was obtained from review of studies: since lifestyle is among important, changeable, and influential factors in fertility, success of these methods can be greatly helped through assessment of lifestyle patterns of infertile couples, and design and implementation of healthy lifestyle counseling programs, before and during implementing assisted fertility techniques.

Abstract
Physiological reproductive aging occurs as a result of a decrease in the number and quality of oocytes in ovarian cortex follicles. Although the reason for the decrease in the quality of the pool and follicular oocytes is not fully understood, endocrine, paracrine, genetic, and metabolic factors are thought to be effective. Nowadays, in order to understand the mechanisms of ovarian aging, genomic research has gained importance. The effect of co-factors, such as telomerase and ceramide, in the ovarian aging process is only getting ascertained with new research studies. The most important tests in the assessment of ovarian aging are antral follicle count and anti-Mullerian hormone.

Abstract
OBJECTIVE To determine the efficacy of using natural family planning (NFP) methods to avoid unintended pregnancy among women of perimenopause age (i.e., age 40-55 years). DESIGN A secondary analysis of subset data from two prospective observational cohort studies. SETTING A university based in-person and online NFP service program. PARTICIPANTS One hundred and sixty couples who used either a website or an in-person NFP service to learn how to avoid pregnancy from January 2001 to November 2012. METHODS A prospective 12-month effectiveness study among 160 women (between ages 40-55) who used NFP to avoid pregnancy. The women used either a hormonal fertility monitor, cervical mucus monitoring, or both to estimate the fertile phase of their menstrual cycles. Survival analysis was used to determine the pregnancy rate over 12 months of use. RESULTS There were a total of five unintended pregnancies among the participants. The typical use pregnancy rate was six per 100 women over 12 months. The monitor alone participants (n = 35) had a 12-month pregnancy rate of three, the participants (n = 73) who used mucus alone had a pregnancy rate of four, and the participants (n = 42) who used the fertility monitor plus mucus had a pregnancy rate of six. CONCLUSION Natural family planning methods can be effective for older women to avoid an unintended pregnancy with correct use and adequate instructions. The pregnancy rate most likely was affected by diminished fertility and motivation to limit family size.

Abstract
STUDY QUESTION Is it possible to construct an age curve denoting the ages above which women are biologically too old to reproduce? SUMMARY ANSWER We constructed a curve based on the distribution of female age at last birth in natural fertility populations reflecting the ages above which women have become biologically too old to have children. WHAT IS KNOWN ALREADY The median age at last birth (ALB) for females is ∼40-41 years of age across a range of natural fertility populations. This suggests that there is a fairly universal pattern of age-related fertility decline. However, little is known about the distribution of female ALB and in the present era of modern birth control, it is impossible to assess the age-specific distribution of ALB. Reliable information is lacking that could benefit couples who envisage delaying childbearing. STUDY DESIGN, SIZE, DURATION This study is a review of high-quality historical data sets of natural fertility populations in which the distributions of female age at last birth were analysed. The studies selected used a retrospective cohort design where women were followed as they age through their reproductive years. PARTICIPANTS/MATERIALS, SETTING, METHODS Using a common set of eligibility criteria, large data files of natural fertility populations were prepared such that the analysis could be performed in parallel across all populations. Data on the ALB and confounding variables are presented as box and whisker plots denoting the 5th, 25th, 50th, 75th and 95th percentile distribution of the age at last birth for each population. The analysis includes the estimation of Kaplan-Meier curves for age at last birth of each population. The hazard curve for ALB was obtained by plotting the smoothed hazard curve of each population and taking the lowest hazard within a time period of at least 5 years. This lowest hazard curve was then transformed into a cumulative distribution function representing the composite curve of the end of biological fertility. This curve was based on the data from three of the six populations, having the lowest hazards of end of fertility. MAIN RESULTS AND THE ROLE OF CHANCE We selected six natural fertility populations comprising 58 051 eligible women. While these populations represent different historical time periods, the distribution of the ages at last birth is remarkably similar. The curve denoting the end of fertility indicates that <3% of women had their last birth at age 20 years meaning that almost 98% were able to have at least one child thereafter. The cumulative curve for the end of fertility slowly increases from 4.5% at age 25 years, 7% at age 30 years, 12% at age 35 years and 20% at age 38 years. Thereafter, it rises rapidly to about 50% at age 41, almost 90% at age 45 years and approaching 100% at age 50 years. LIMITATIONS, REASONS FOR CAUTION It may be argued that these historical fertility data do not apply to the present time; however, the age-dependent decline in fertility is similar to current populations and is consistent with the pattern seen in women treated by donor insemination. Furthermore, for reproductive ageing, we note that it is unlikely that such a conserved biological process with a high degree of heritability would have changed significantly within a century or two. WIDER IMPLICATIONS OF THE FINDINGS We argue that the age-specific ALB curve can be used to counsel couples who envisage having children in the future. Our findings challenge the unsubstantiated pessimism regarding the possibility of natural conception after age 35 years. STUDY FUNDING/COMPETING INTEREST(S) No external funding was either sought or obtained for this study. There are no conflicts of interest to be declared.

Abstract
OBJECTIVE Studies have shown that excess body fat negatively affects reproductive functions in females. However, whether obesity affects the ovarian follicle development and ovarian lifespan and the underlying mechanism has not been well elucidated. The aim of the present study was to investigate the association between obesity and ovarian follicle development. METHODS Adult female Sprague-Dawley rats (n = 36) were randomly divided into three groups: the normal control (NC) group, the caloric restriction (CR) group (fed 70% food of the NC group) and the high-fat diet (HF) group. They were maintained on these regimens for 18 weeks. RESULTS The body weight, ovary weight and visceral fat in the HF group were significantly higher than those in the NC group and the CR group at the end of treatment. Histological analysis showed that the HF rats had significantly less number and percentage of primordial follicles, but greater number and percentage of developing and atretic follicles than the NC rats and CR rats. Western blot analysis demonstrated that the level of mTORC1 and p-S6K1 proteins significantly increased in the ovaries of HF rats, whereas that of SIRT1, SIRT6, FOXO3a and NRF-1 decreased compared to the NC rats. In contrast, the expression of mTORC1 and p-S6K1 dramatically declined, while that of SIRT1, SIRT6, FOXO3a and NRF1 increased in the ovaries of CR rats. CONCLUSIONS Our study suggests that the HF diet induced obesity may accelerate the ovarian follicle development and rate of follicle loss through activating mTOR and suppressing SIRT1 signaling, thus leading to POF, and that CR may inhibit the activation of primordial follicles, follicular development and loss, thus extending the ovarian lifespan through suppressing mTOR and activating SIRT1 signaling.

Abstract
It is well known that maternal ageing not only causes increased spontaneous abortion and reduced fertility, but it is also a high genetic disease risk. Although assisted reproductive technologies (ARTs) have been widely used to treat infertility, the overall success is still low. The main reasons for age-related changes include reduced follicle number, compromised oocyte quality especially aneuploidy, altered reproductive endocrinology, and increased reproductive tract defect. Various approaches for improving or treating infertility in aged women including controlled ovarian hyperstimulation with intrauterine insemination (IUI), IVF/ICSI-ET, ovarian reserve testing, preimplantation genetic diagnosis and screening (PGD/PGS), oocyte selection and donation, oocyte and ovary tissue cryopreservation before ageing, miscarriage prevention, and caloric restriction are summarized in this review. Future potential reproductive techniques for infertile older women including oocyte and zygote micromanipulations, derivation of oocytes from germ stem cells, ES cells, and iPS cells, as well as through bone marrow transplantation are discussed.

Abstract
The reproductive system of human female exhibits a much faster rate of aging than other body systems. Ovarian aging is thought to be dominated by a gradual decreasing numbers of follicles, coinciding with diminished quality of oocytes. Menopause is the final step in the process of ovarian aging. This review focuses on the mechanisms underlying the ovarian aging involving a poor complement of follicles at birth and a high rate of attrition each month, as well as the alternated endocrine factors. We also discuss the possible causative factors that contribute to ovarian aging, e.g., genetic factors, accumulation of irreparable damage of microenvironment, pathological effect and other factors. The appropriate and reliable methods to assess ovarian aging, such as quantification of follicles, endocrine measurement and genetic testing have also been discussed. Increased knowledge of the ovarian aging mechanisms may improve the prevention of premature ovarian failure.

Abstract
The current trends to postpone motherhood and the increase in demand for assistance in reproductive medicine highlight the need for seeking guidelines for the establishment of individualized treatment protocols. Currently available ovarian reserve tests do not provide sufficient evidence to be solely considered ideal, but they may occupy important place in initial counseling, predicting unsatisfactory results that could be improved by individualized induction schemes and reducing excessive psychological and financial burdens, and adverse effects. In this paper, we revise the role of hormonal basal and dynamic tests, as well as ultrasonographic markers, as ovarian reserve markers, in order to provide embasement for propaedeutic strategies and their interpretation in order to have reproductive success.

Abstract
GOALS Gynecologic cancers represent a significant proportion of malignancies affecting women. Historically, cancer treatment focused primarily on eradicating disease, irrespective of the impact on fertility. The implementation of early detection protocols and advanced treatment regimens has resulted in improved prognosis for gynecologic cancer patients. With this improvement, more attention is now paid to quality-of-life issues. Fertility preservation (FP) has become an integral component in the selection and execution of gynecological cancer management. In this report we address gynecologic malignancies as they relate to future fertility potential. METHODS We review reproductive principles such as ovarian reserve, uterine function, cervical competence, and early obstetrical management, as well as available FP methods. In addition, we discuss the potential damage that cancer and cancer treatments can impart on the female reproductive system. We offer general recommendations regarding baseline screening tests useful in assessing the feasibility of FP. Lastly, cancer-specific FP methods are presented. RESULTS Oocyte quantity and quality naturally decline with advancing age. In most patients, the slope of decline steepens significantly after the age of 35. Reliable ovarian reserve measures exist and should be utilized to assess and triage potential candidates for FP. Advancements in FP, particularly in oocyte cryopreservation (OC), have improved the success rates associated with the techniques available to cancer patients. Currently, where successfully available, OC appears to be the preferred method for single women diagnosed with a gynecologic malignancy as it affords reproductive autonomy, whereas embryo cryopreservation using a donor gamete remains an alternative. CONCLUSIONS In gynecologic oncology, effective treatments to achieve cancer survival can compromise the ability to subsequently conceive and/or carry a child. Therefore, as the field of oncofertility continues to expand, a discussion regarding FP should be initiated when tailoring a cancer treatment protocol.

Abstract
Two patients with severely diminished ovarian reserve who were refractory to aggressive ovarian stimulation conceived with oocytes from prematurely developing antral follicles after dehydroepiandrosterone supplementation. The first patient had 11 and 14.5 mm, and the second patient had 13 mm antral follicles on cycle days 2 and 3 respectively. In the first case, no ovarian stimulation was performed, while the second case received one dose of gonadotrophins with a gonadotrophin-releasing hormone antagonist. Following very early human chorionic gonadotrophin (HCG) triggering on cycle day 5, when antral follicles reached 15 and 18.5 mm in the first case, and 19 mm in the second case, IVF intracytoplasmic sperm injection treatment resulted in pregnancies in both cases, which are currently ongoing at 35 and 14 weeks of gestation. The results in these patients show that pregnancy can be achieved in poor responder patients with prematurely developing antral follicles following early HCG triggering based on follicle size rather than cycle day, with no or minimal stimulation. Whether DHEA supplementation had any impact on the success of these cycles remains to be determined.

Abstract
BACKGROUND The ovaries are the primary targets of senescence effects in mammalian and avian species. In the present study, relationships between reproductive aging, sex steroids and the growth pattern of the pre-ovulatory follicle wall were investigated using young hens with long clutch (YLC), old hens with long clutch (OLC), old hens with short clutch (OSC), and old hens with interrupted long clutch (OILC). METHODS Experiment 1: Hens were sacrificed 1.5 and 14.5 h after ovulation. Experiment 2: YLC and OILC hens were sacrificed 3.5 h after treatments with LH and/or aminoglutethimide (AG), an inhibitor of steroid synthesis. Volumes of pre-ovulatory follicles (F1-F5) and plasma concentrations of ovarian steroids were determined. Experiment 3: Granulosa and theca cells from F3 follicles of OSC and/or YLC hens were exposed in vitro to estradiol-17beta (E2), testosterone (T) and LH and the proliferative activity of the cells was examined using CellTiter 96 Aqueous One Solution Assay. RESULTS In YLC and OLC groups, the total volume of F1-F5 follicles rose between 1.5 and 14.5 h after ovulation (P < 0.01), negatively correlating with the plasma level of E2 (P < 0.01). There was no growth of pre-ovulatory follicles in the middle of the ovulatory cycle in the OSC group, with a positive correlation being present between E2 and the follicular volume (P < 0.05). In young hens, AG caused a rise in the total follicular volume. This rise was associated with a fall in E2 (r = -0.54, P < 0.05). E2 enhanced proliferation of granulosa cells from YLC and OSC groups. The proliferative activity of granulosa and theca cells of YLC hens depended on the interaction between T and LH (P < 0.01). CONCLUSIONS These data indicate for the first time that the growth pattern of pre-ovulatory follicles during the ovulatory cycle changes in the course of reproductive aging. E2 seems to play a dual role in this adjustment; it stimulates the growth of the follicular wall in reproductive aged hens, whereas it may inhibit this process in young birds. T and LH are apparently involved in the growth regulation during the pre-ovulatory surge in young hens.

Abstract
Menopause is the final step in the process referred to as ovarian ageing. The age related decrease in follicle numbers dictates the onset of cycle irregularity and the final cessation of menses. The parallel decay in oocyte quality contributes to the gradual decline in fertility and the final occurrence of natural sterility. Endocrine changes mainly relate to the decline in the negative feedback from ovarian factors at the hypothalamo-pituitary unit. The declining cohort of antral follicles with age first results in gradually elevated FSH levels, followed by subsequent stages of overt cycle irregularity. The gradual decline in the size of the antral follicle cohort is best represented by decreasing levels of anti-Mullerian hormone. The variability of ovarian ageing among women is evident from the large variation in age at menopause. The identification of women who have severely decreased ovarian reserve for their age is clinically relevant. Ovarian reserve tests have appeared to be fairly accurate in predicting response to ovarian stimulation in the assisted reproductive technology (ART) setting. The capacity to predict the chances for spontaneous pregnancy or pregnancy after ART appears very limited. As menopause and the preceding decline in oocyte quality seem to have a fixed time interval, tests that predict the age at menopause may be useful to assess individual reproductive lifespan. Especially genetic studies, both addressing candidate gene and genome wide association, have identified several interesting loci of small genetic variation that may determine fetal follicle pool development and subsequent wastage of his pool over time. Improved knowledge of the ovarian ageing mechanisms may ultimately provide tools for prediction of menopause and manipulation of the early steps of folliculogenesis for the purpose of contraception and fertility lifespan extension.

Abstract
In modern society with women delaying pregnancy, predicting the age of the natural menopause with its preceding infertility will allow making informed choices about when to try starting to have children. Also if premature menopause could be predicted in young women, strategies could be instigated to reduce the long term health risks of early estrogen deficiency. This review examines the physiology of ovarian ageing, with the menopause being the final outcome. Long and short term predictive markers of the age of the menopause and the preceding natural infertility are evaluated. Many subtle changes in the endocrine regulation of ovarian function with advancing age may seem interesting but currently are not clinically useful as a predictive test. Examples are changes in concentrations of estradiol, progesterone, luteinizing hormone (LH) and activin, as well as follicle dynamics. Other features hold more promise. Among these are chronological age, family history, anti-Müllerian hormone (AMH), poor response to in vitro fertilization (IVF), basal follicle-stimulating hormone (FSH) and the antral follicle count for long term prediction. For short term prediction, cycle shortening and occurrence of vasomotor symptoms may prove useful. To date, none of these markers has been found to have sufficient predictive accuracy in individual women. Results of new and ongoing longitudinal studies may provide better predictive models. In particular, use of genetic profiles may add to the accuracy of currently known markers.

Abstract
OBJECTIVE The menopausal transition is characterized by irregular menstrual cycles and unpredictable hormone levels, including dramatic swings in estradiol (E2). An increasing number of studies have found variable high E2 and low luteal phase progesterone occur with progression of Stages of Reproductive Aging Workshop (STRAW)stage, but the cause remains unclear. To explore the causes of the erratic changes in E2, individual within-cycle secretion patterns of E2, progesterone, follicle-stimulating hormone, luteinizing hormone, inhibin A, and inhibin B were explored in detail. DESIGN Blood samples taken three times per week over 1 1/3 menstrual cycles from 77 women aged 21 to 55 classified as mid-reproductive age (STRAW stages 5 and 4; n = 21), late-reproductive age (STRAW stages 4 and 3; n = 16), early menopausal transition (STRAW stage 2; n = 17), and late menopausal transition (STRAW stage 1; n = 23) were analyzed. RESULTS Eleven of the 29 (37%) early and late menstrual transition ovulatory cycles exhibited a specific pattern of E2 secretion that was characterized by a second increase in E2 during the mid- and late luteal phases and that continued to a peak during the subsequent menstrual phase. This second rise and fall in E2 was typical in appearance of a normal follicular phase, except that it was superimposed on an existing ovulatory cycle(specifically during the luteal and menstrual phases). The pattern was therefore referred to as a luteal out-of-phase(LOOP) follicular event. In four of these LOOP cycles, a luteinizing hormone peak and ovulatory episode followed the second E2 peak early in the subsequent cycle. Compared with the typical ovulatory cycles, the cycles with LOOP events exhibited lower luteal phase progesterone, higher early cycle follicle-stimulating hormone, and lower early cycle inhibin B. They were also associated with abnormally short (<21 d) or long (>40 d) cycle length. CONCLUSIONS Many of the marked increases in ovulatory cycle E2 and cycle irregularities during the menopausal transition may be due to LOOP events and appear to be triggered by prolonged high follicular phase follicle-stimulating hormone levels.

Abstract
PURPOSE Variability in menstrual cycle length, largely determined by variation in follicular phase length, is related to several health outcomes, yet the causes of this variability are incompletely understood. We sought to identify characteristics associated with follicular phase length. METHODS We used the North Carolina Early Pregnancy Study to describe factors correlated with timing of ovulation (follicular phase length). Women collected daily urine specimens and recorded vaginal bleeding. Specimens were assayed for estrone 3-glucuronide and pregnanediol 3-glucuronide, which in turn were used to estimate the day of ovulation. All other variables were assessed through interview. Associations with follicular phase length were evaluated using a multiple regression model. RESULTS We determined follicular phase length for the first cycles of 201 women. Women with a history of miscarriage tended to have shorter follicular phases (2.2 days). Longer duration of oral contraceptive (OC) use and recent OC use (in the last 90 days) were both correlated with longer follicular phase. Occasional marijuana users (up to three times in the last 3 months) had a longer follicular phase than nonusers (3.5 days); the follicular phase in frequent users (more than three times) was almost 2 days longer than that of nonusers. CONCLUSIONS The association between marijuana use and longer follicular phase is consistent with prior rhesus monkey research that shows ovulatory delay or inhibition.

Abstract
Rising serum FSH levels is one of the earliest signs of human female reproductive aging. Whether or not elevated FSH remains a passive reflection of a diminishing ovarian follicle pool or actively contributes to declining female fertility with age has not been established. We therefore investigated female reproduction in mice expressing progressively rising serum levels of transgenic human FSH (Tg-FSH, 2.5-10 IU/liter) independently of follicle depletion. We show that serum LH and estradiol levels and uterine size remained normal in Tg-FSH females, whereas ovarian weight and corpora lutea number were significantly increased up to 1.3- and 5-fold, respectively. Furthermore, the monotrophic FSH rise produced a striking biphasic effect on female fertility. Tg-FSH females less than 22 wk old delivered increased litter sizes, then beyond 23 wk, litter sizes decreased rapidly culminating in premature infertility despite continued ovary follicle development, and increased ovulation and uterine embryo implantation sites as well as normal serum levels of anti-Mullerian hormone, a marker of ovarian follicle reserve. We found that rising circulating Tg-FSH produced premature infertility by increasing embryo-fetal resorption and parturition failure with age. Thus, our Tg-FSH mice present a novel paradigm to investigate selective contributions of elevated FSH to age-related female infertility, which revealed that rising FSH levels, despite no exhaustion of ovarian reserve, actively accelerates female reproductive aging primarily by postimplantation reduction of embryo-fetal survival.

Abstract
This article considers methodology for hierarchical functional data analysis, motivated by studies of reproductive hormone profiles in the menstrual cycle. Current methods standardize the cycle lengths and ignore the timing of ovulation within the cycle, both of which are biologically informative. Methods are needed that avoid standardization, while flexibly incorporating information on covariates and the timing of reference events, such as ovulation and onset of menses. In addition, it is necessary to account for within-woman dependency when data are collected for multiple cycles. We propose an approach based on a hierarchical generalization of Bayesian multivariate adaptive regression splines. Our formulation allows for an unknown set of basis functions characterizing the population-averaged and woman-specific trajectories in relation to covariates. A reversible jump Markov chain Monte Carlo algorithm is developed for posterior computation. Applying the methods to data from the North Carolina Early Pregnancy Study, we investigate differences in urinary progesterone profiles between conception and nonconception cycles.
