OBJECTIVE To determine whether or not the level of serum anti-Müllerian hormone (AMH) is related to early ovarian aging in young women (< 35 years of age) undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles. DESIGN Retrospective cohort study. SETTING An IVF laboratory in a university hospital in Taiwan. Patient (s): 70 young women (< 35 years of age) with ...
The number of ovarian follicles declines with age resulting in a significant decrease of fertility by the age of 40. However, the age when follicle loss starts to affect ovarian endocrine function is not well recognized. The purpose of the present study was to investigate age-related ovarian/adrenal androgen secretion, which is crucial for estrogen biosynthesis in healthy women and in women wit...
Objective: To assess whether the quality of early childhood environments among different groups of Bangladeshi women, including migrants to the UK, contributes to variation in ovarian reserve and the rate of reproductive ageing in later life. Design: Cross-sectional study. Setting: London (UK) and Sylhet town, NE Bangladesh. Patients: 179 healthy women volunteers aged 35-59 divided into four gr...
The reproductive sequelae of cancer treatments may provide an important model of accelerated ovarian aging. Tens of thousands of women treated for cancer each year experience infertility and early menopause as a result of treatment. A spectrum of reproductive compromise commonly ranges from immediate menopause at the time of cancer treatment to the less proximate outcome of early menopause in t...
Primary ovarian insufficiency (POI) is a critical fertility defect characterized by an anticipated and silent impairment of the follicular reserve, but its pathogenesis is largely unexplained. The frequent maternal inheritance of POI together with a remarkable dependence of ovarian folliculogenesis upon mitochondrial biogenesis and bioenergetics suggested the possible involvement of a generaliz...
