background: reduced ovarian reserve has been known to predict poor ovarian response and poor success rates in infertile women undergoing assisted reproductive technology. ovarian reserve also decreases with age but the rate of decline defers from a woman to another. the aim of this study was to detect any difference in ovarian reserve as measured by basal serum fsh and amh between matched cohor...
Screening asymptomatic women in the general population for ‘early ovarian ageing’ will be more effective in highrisk groups. Recent findings support the hypothesis that women with polycystic ovaries (PCO) may have actually been born with a larger pool of resting follicles. The mechanism is almost certainly genetic and occurs in fetal life. If, as is widely accepted, the rate of depletion of the...
The gradual increase in follicle stimulating hormone (FSH) concentrations in women approaching menopause results from the depletion of the ovarian follicular pool, a process referred to as 'ovarian ageing'. This study investigates whether variable endogenous FSH concentrations, as have been observed in normo-ovulatory young women, are related to menstrual cycle characteristics, including predic...
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. ...
It is well known that maternal ageing not only causes increased spontaneous abortion and reduced fertility, but it is also a high genetic disease risk. Although assisted reproductive technologies (ARTs) have been widely used to treat infertility, the overall success is still low. The main reasons for age-related changes include reduced follicle number, compromised oocyte quality especially aneu...
Ovarian reserve is an estimate of the primordial follicle pool in the ovaries and is indicative of the reproductive age of a woman. This estimate helps in assessing a woman’s reproductive potential, in predicting her possible response in assisted conception, and in screening women for “early ovarian ageing” as a possible cause for subfertility. Over the years, several methods have been used for...
