Early ovarian ageing.
Observations from reproductive biology, epidemiology, and clinical assisted reproduction support the hypothesis that the time interval between the onset of accelerated decline of the ovarian reserve and the menopause is more or less fixed. Thus, it is estimated that women who become menopausal by the age of 45 may have experienced an accelerated decline of their fertility before the age of 32. Up to 10% of women in the general population may fall into this category, which has been described as "early ovarian ageing". Because of the long latent phase and predictable natural history, this condition is suitable for screening. High-risk groups include, women with a family history of early menopause. IVF has provided a model for the development of ovarian reserve tests, some of which appear promising as potential screening tools for the detection of early ovarian ageing in asymptomatic women in the general population.
