Abstract
Previously, this study group found that female childhood cancer survivors could be at risk of early cessation of fertility. The aim of the present study was to evaluate reproductive function in the same group of survivors 10 years after the initial study. Of the original cohort of 100, 71 were re-examined. Thirty-six survivors reported regular menstrual cycles. When they were compared with 210 controls, they differed significantly in antral follicle count (AFC) (median 15 versus 18, P=0.047) but not in anti-Müllerian hormone (AMH) (median 13.0 versus 17.8 pmol/l). Survivors cured with minimal gonadotoxic treatment had significantly higher AMH and AFC compared with survivors cured with either potentially gonadotoxic treatment or treatment including alkylating chemotherapy and ovarian irradiation (20.0, 5.8 and

Abstract
Do infertile patients below the age of 40 years have a lower ovarian reserve, estimated by anti-Müllerian hormone (AMH) and total antral follicle count (AFC), than women of the same age with no history of infertility?
Serum AMH and AFC were not lower in infertile patients aged 20-39 years compared with a control group of the same age with no history of infertility. WHAT IS KNOWN ALREADY?: The management of patients with a low ovarian reserve and a poor response to controlled ovarian stimulation (COS) remains a challenge in assisted reproductive technologies (ART). Both AMH levels and AFC reflect the ovarian reserve and are valuable predictors of the ovarian response to exogenous gonadotrophins. However, there is a large inter-individual variation in the age-related depletion of the ovarian reserve and a broad variability in the levels of AMH and AFC compatible with conception. Women with an early depletion of the ovarian reserve may experience infertility as a consequence of postponement of childbearing. Thus, low ovarian reserve is considered to be overrepresented among infertile patients.
A prospective cohort study including 382 women with a male partner referred to fertility treatment at Rigshospitalet, Copenhagen, Denmark during 2011-2013 compared with a control group of 350 non-users of hormonal contraception with no history of infertility recruited during 2008-2010.
Included patients and controls were aged 20-39 years. Women with polycystic ovary syndrome were excluded. On Cycle Days 2-5, AFC and ovarian volume were measured by transvaginal sonography, and serum levels of AMH, FSH and LH were assessed.
Infertile patients had similar AMH levels (11%, 95% confidence interval (CI): -1;24%) and AFC (1%, 95% CI: -7;8%) compared with controls with no history of infertility in an age-adjusted linear regression analysis. The prevalence of very low AMH levels (

Abstract
Is the ovarian reserve in a woman at a given age associated with her mother's age at menopause?
We demonstrated a significant, positive association between age at maternal menopause and serum anti-Müllerian hormone (AMH) levels and antral follicle count (AFC) in daughters. The rate of decline in serum-AMH level and AFC is also associated with age at maternal menopause.
The association between menopausal age in mothers and daughters has been established through several epidemiological studies. This paper shows that early maternal menopause is related to an advanced depletion of the ovarian reserve and that late maternal menopause is related to a delayed depletion.
Cross-sectional data were obtained from a prospective cohort study of 863 women. The study comprised 527 participants from this prospective cohort whose mothers' age at natural menopause was known.
Participants were recruited from female health care workers aged 20-40 years employed at Copenhagen University Hospital, Rigshospitalet, and were enrolled in the study between September 2008 and February 2010. The response rate was 52.1%. Endocrine and ovarian parameters related to reproductive ageing (AMH and AFC) were assessed by serum AMH analyses and transvaginal ovarian sonography on cycle Day 2-5. Data on reproductive history, including age at natural maternal menopause, were obtained through an internet-based questionnaire. We used an analysis of covariance model with serum-AMH and AFC as outcomes, age as the quantitative predictor and onset of maternal menopause as the categorical predictor, with further adjustments for BMI, use of oral contraceptives, participants' smoking habits and prenatal smoking exposure.
We found a significant effect of age at maternal menopause on both serum AMH levels (P

Abstract
It remains controversial whether anti-Müllerian hormone (AMH) concentration is influenced by hormonal contraception. This study quantified the effect of hormonal contraception on both endocrine and sonographic ovarian reserve markers in 228 users and 504 non-users of hormonal contraception. On day 2-5 of the menstrual cycle or during withdrawal bleeding, blood sampling and transvaginal sonography was performed. After adjusting for age, ovarian reserve parameters were lower among users than among non-users of hormonal contraception: serum AMH concentration by 29.8% (95% CI 19.9 to 38.5%), antral follicle count (AFC) by 30.4% (95% CI 23.6 to 36.7%) and ovarian volume by 42.2% (95% CI 37.8 to 46.3%). AFC in all follicle size categories (small, 2-4 mm; intermediate, 5-7 mm; large, 8-10 mm) was lower in users than in non-users of hormonal contraception. A negatively linear association was observed between duration of hormonal-contraception use and ovarian reserve parameters. No dose-response relation was found between the dose of ethinyloestradiol and AMH or AFC. This study indicates that ovarian reserve markers are lower in women using sex steroids for contraception. Thus, AMH concentration and AFC may not retain their accuracy as predictors of ovarian reserve in women using hormonal contraception. Serum anti-Müllerian hormone (AMH) concentration is an indirect marker of the number of small follicles in the ovary and thereby the ovarian reserve. The AMH concentration is now widely used as one of the markers of the ovarian reserve in ovarian hormonal stimulation regimens. Hence the AMH concentration in a patient is used to decide the dose of the ovarian hormonal stimulation prior to IVF treatment. In some infertile patients, hormonal contraception is used prior to ovarian hormonal stimulation and therefore it is important to clarify whether serum AMH concentration is influenced by the use of sex steroids. The aim of this study was to quantify the potential effect of hormonal contraception on the ovarian function by hormonal analyses and ovarian ultrasound examination. Examinations were performed in the early phase of the menstrual cycle or the hormone-free interval of hormonal contraception. We compared the AMH concentration, the antral follicle count (AFC) and the ovarian volume in 228 users versus 504 non-users of hormonal contraception. Users of hormonal contraception had 29.8% lower AMH concentration, 30.4% lower AFC and 42.2% lower ovarian volume than non-users. These findings were more pronounced with increasing duration of hormonal contraception. No dose-response relation was found between the dose of ethinylestradiol and the impact on serum AMH and AFC. The study indicates that ovarian reserve markers are lower in women using sex steroids for contraception. Thus, serum AMH concentration and AFC may not retain their accuracy as predictors of the ovarian reserve in women using hormonal contraception.

Abstract
What is the prevalence in a normal population of polycystic ovary syndrome (PCOS) according to the Rotterdam criteria versus revised criteria including anti-Müllerian hormone (AMH)?
The prevalence of PCOS was 16.6% according to the Rotterdam criteria. When replacing the criterion for polycystic ovaries by antral follicle count (AFC) > 19 or AMH > 35 pmol/l, the prevalence of PCOS was 6.3 and 8.5%, respectively. WHAT IS KNOWN ALREADY?: The Rotterdam criteria state that two out of the following three criteria should be present in the diagnosis of PCOS: oligo-anovulation, clinical and/or biochemical hyperandrogenism and polycystic ovaries (AFC = 12 and/or ovarian volume >10 ml). However, with the advances in sonography, the relevance of the AFC threshold in the definition of polycystic ovaries has been challenged, and AMH has been proposed as a marker of polycystic ovaries in PCOS.
From 2008 to 2010, a prospective, cross-sectional study was performed including 863 women aged 20-40 years and employed at Copenhagen University Hospital, Rigshospitalet, Denmark.
We studied a subgroup of 447 women with a mean (±SD) age of 33.5 (±4.0) years who were all non-users of hormonal contraception. Data on menstrual cycle disorder and the presence of hirsutism were obtained. On cycle Days 2-5, or on a random day in the case of oligo- or amenorrhoea, sonographic and endocrine parameters were measured.
The prevalence of PCOS was 16.6% according to the Rotterdam criteria. PCOS prevalence significantly decreased with age from 33.3% in women 19 or AMH > 35 occurred in 17.7 and 23.0%, respectively. The occurrence of AFC > 19 or AMH > 35 in the age groups 19 or AMH > 35 pmol/l, the prevalence of PCOS was 6.3 or 8.5%, respectively, and in the age groups
