The number of primary oocytes in a female decreases continually throughout her reproductive life, from puberty to menopause. At birth, a female typically has about 1-2 million primary oocytes, but most of these will degenerate and be lost before she reaches puberty. By the time a female reaches menopause, the number of primary oocytes remaining is very small, typically only a few thousand.
