Earlier onset of menopause in women affects the ability of her daughters children
Woman can assess their level of fertility, based on data about the beginning of menopause, her mother. For example, women whose mothers came early in menopause, have fewer eggs in the ovaries, say Danish experts.
According to BBC, the study 527 women 20-40 years included two methods to estimate fertility: the level antimyullerovskogo hormone (AH) and the number of antral follicles (CAF). As is known, the number of eggs in a woman determined from birth. According to these two factors, you can understand how much egg left.
These rates declined rapidly in women, when their mother comes early menopause (before age 45), compared with women whose mothers experienced menopause after age 55. The average level of hypertension was reduced by 8.6%, 6.8% and 4.2% per year in women with mothers with early, normal and late menopause, respectively. A similar trend was observed with respect to CAF – 5,8%, 4,7% and 3,2%.
Believed between reduced fertility and the onset of menopause is about 20 years. That is, if menopause comes in 45 years, the decline begins at 25. According to Joan Bentzen, hereditary factors play a key role. It also specifies: a small number of eggs does not mean that a woman will have less children. Also yet to conduct long-term observations.
