I'm an aspiring ob/gyn. just curious how the process of menopause exactly works in the woman's body??

A complex process: Menopause is the cessation of menstruation in women. Menstrual cycles are determined by ovarian follicles, tiny units in the ovary, that contains the oocyte or ' the egg'. Each female is born with a finite number of follicles. As age progresses, these follicles become smaller and less senstive to hormones and eventually shut down.
