What changes can i expect in hormones from menarche to menopause?

A doctor has provided 1 answer

Rising, then falling: Estrogen levels first rise at the time of menarche, which is the time of the first menstrual flow, about age 11-13 for most girls. Estrogen is the principle female hormone that causes breast development and helps prepare for pregnancy. Regular menstrual cycles then occur until age 52 or so, when estrogen levels fall and menopause occurs, the cessation of menstrual periods.
