OBJECTIVES By requiring a minimum of two of three items [hyperandrogenism (HA), oligoanovulation (OA), and polycystic ovaries (PCO) at ultrasound], the Rotterdam definition recognizes four PCO syndrome (PCOS) phenotypes: HA+OA+PCO (full-blown syndrome), HA+OA (former National Institutes of Health definition), HA+PCO (ovulatory PCOS), and OA+PCO. However,(More)
BACKGROUND AND OBJECTIVE Mutations in bone morphogenic protein 15 (BMP15) and growth/differentiation factor 9 (GDF9) lead to altered fertility in animal models. In the human, a heterozygous point mutation of BMP15 has been associated with premature ovarian failure (POF). SUBJECT AND METHODS We have directly sequenced both genes in a cohort of 203 POF(More)
CONTEXT We previously hypothesized that the excess of anti-müllerian hormone (AMH) at the level of selectable follicles could be involved in the follicular arrest of polycystic ovary syndrome (PCOS), mainly through inhibition of FSH effect on aromatase expression. OBJECTIVE In this study, we investigated whether a decrease in the serum AMH level was(More)
BACKGROUND Premature ovarian failure (POF) is defined as amenorrhoea for more than 6 months, occurring before the age of 40, with an FSH serum level higher than 40 mIU/ml. Cytogenetically visible rearrangements of the X chromosome are associated with POF. Our hypothesis was that cryptic Xq chromosomal rearrangements could be an important etiological(More)
BACKGROUND We previously hypothesized that the excess of 2-5 mm follicles seen at ovarian ultrasonography might be involved in the follicular arrest (FA) of polycystic ovary syndrome (PCOS), independently from the main putative contributors of FA, namely hyperandrogenism and hyperinsulinism. METHODS A multivariate statistical analysis was applied(More)
