Sperm are produced daily throughout a lifetime but human eggs are finite and found in two ovaries near about about 1-2 million immature eggs, or follicles.
Over a lifetime, the vast majority of follicles will die through a process known as atresia. Atresia begins at birth and continues throughout the course of the reproductive life.
When puberty is reached and menstruation begins, only about 400,000 follicles remain. With each menstrual cycle, a thousand follicles are lost and only one follicle will actually mature into an ovum (egg), which is released into the fallopian tube, called as ovulation.
That means that of the one to two million follicles, only approximate 400 will ever mature.(12 * average reproductive years)
