Quizplus · Accepted Answer

Females are born with a fixed number of primary oocytes, and this number decreases continually throughout her reproductive life from puberty to menopause. At menopause, there is a depletion of primary oocytes in the ovaries, which leads to the end of reproductive capability. There is no replacement of new primary oocytes to maintain the number constant throughout reproductive life.
