Postmenopausal women have an increased risk for cardiovascular diseases. It has been postulated that the loss of ovarian function and subsequent deficiency of endogenous estrogens after menopause contributes to this elevated risk of cardiovascular di

Objective: The World Health Organization (WHO) has defined three classes of anovulatory infertility, based on serum gonadotrophin and oestradiol levels: low gonadotrophin and oestradiol levels in women with WHO 1 anovulation, normal hormone levels in

Objective Fertility is reduced in women with rheumatoid arthritis (RA), even before diagnosis. This may be due to a diminished ovarian reserve. The current study examined serum levels of anti–Mullerian hormone (AMH), the most reliable endocrine mar

Primary ovarian insufficiency (POI), also known as premature ovarian failure, is a disorder of infertility characterized by amenorrhoea, low estrogen levels and increased gonadotropin levels in women aged

OBJECTIVE: To describe changes of anti-Müllerian hormone (AMH) and inhibin B during low-dose gonadotropin ovulation induction (OI) treatment in women with polycystic ovary syndrome (PCOS), and thus disturbed selection of the dominant follicle.DESIGN

Introduction: Normogonadotropic (World Health Organization category II) anovulation is the most frequent cause of reduced fertility. Anovulation is associated with endocrine changes, i.e. hyperandrogenism, obesity, and insulin resistance. However, th

BACKGROUND The aim was to assess possible treatment-induced gonadal damage in a cohort of adult female childhood cancer survivors (CCS) using anti-Mullerian hormone (AMH), the most sensitive marker of ovarian reserve. METHODS A total cohort of 185 su

According to the threshold concept, FSH concentrations need to surpass a distinct level to stimulate ovarian follicle growth. The window concept stresses the significance of a limited duration of elevated FSH levels above the threshold for single dom

OBJECTIVE The mechanism of dominant follicle selection remains obscure.We have investigated the association between follicle diameter and follicular steroid levels in individual human ovarian follicles throughout the menstrual cycle. DESIGN Fluid fro
