BACKGROUND Reduced ovarian reserve predicts poor ovarian response and poor suc- cess rates in infertile women who undergo assisted reproductive technology (ART). Ovarian reserve also decreases with age but the rate of decline varies from one woman to another. This study aims to detect differences in ovarian reserve as measured by basal serum follicle stimulating hormone (FSH) and anti-Müllerian...

BACKGROUND We have shown recently that maternal undernutrition (UN) advanced female pubertal onset in a manner that is dependent upon the timing of UN. The long-term consequence of this accelerated puberty on ovarian function is unknown. Recent findings suggest that oxidative stress may be one mechanism whereby early life events impact on later physiological functioning. Therefore, using an est...

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 delay in childbearing is an important societal change contributing to an increasing incidence of subfertility. The prevailing concept of female reproductive ageing assumes that the decline of both quantity and quality of the oocyte/follicle pool determines an age-dependent loss of female fertility. There is an apparent discrepancy between the ability to maintain a regular ovulatory cycle pa...

A 7½-year-old girl is reported showing pre­cocious puberty and large abdominal mass for a year. The right ovarial cyst removed by surgery revealed histopathologically a granu­losa cell tumor. After removal of the tumor the estrogens were still increased and the signs of puberty showed no regression. This seems to be due to the hormonal activity of the metas­tases. Liver metastasis was present a...

BACKGROUND Anti-Müllerian hormone (AMH) is produced by the granulosa cells of preantral and small antral follicles and its levels can be assessed in serum. Since the number of ovarian follicles declines with increasing age, AMH levels might be used as a marker for ovarian ageing. Therefore, we studied the relationship between AMH levels and ovarian response during ovarian stimulation for IVF. ...

BACKGROUND Anti-Müllerian hormone (AMH), produced by growing pre-antral and early antral ovarian follicles, has been shown to be a useful marker for ovarian ageing. Serum AMH concentrations are elevated during reproductive life in anovulatory women, especially in those patients exhibiting polycystic ovaries (PCO). The current study was designed to investigate whether the decrease in AMH serum c...
