Quizplus · Accepted Answer

At birth, a female has about one to two million primary oocytes in her ovaries. Only about 400,000 of these oocytes remain at puberty, and only about 400 of these oocytes will actually ovulate during the reproductive years. The oocytes initiate their division during fetal life but do not complete it until just before ovulation. Typically, only one oocyte matures and is released during a menstrual cycle. Therefore, option B is correct as it states that all ova are contained in the female's ovaries at birth.
