Menopause is the final marker of the end of a woman’s reproductive period. Natural menopause occurs between the age of 40 and 60 years in most women. Early menopause (<45years old) is associated with increased risk of cardiovascular disease and all-cause mortality, and late menopause (55years old) increases the risk of certain hormone-related cancers after menopause. Although genetic factors play a role, the mechanisms underlying the timing of menopause are not well understood. Previous studies suggest that factors in very early life may influence age at menopause. A woman is born with a certain number of ovarian follicles, and menopause occurs when the number of ovarian follicles has decreased to a critically low level. It is assumed that no new ovarian follicles are developed after the 20th week of fetal life, and that atresia of the ovarian follicles follows thereafter. Thus, the initial number of ovarian follicles and the speed of follicle atresia during fetal life, may be important for a woman’s number of ovarian follicles at birth, and thereby the timing of her menopause.
