I am afraid that is now an incorrect statement. Recently it has been proven that women produce ovum throughout their fertile period, which makes sense as every living cell in the body is replaced over 2 years.
This is quite different from eggs - a girl is born with the maximum number of eggs she will have as a woman.
White et al. disproved the longstanding dogma that all of the ova are produced before birth. The team from the Vincent Center for Reproductive Biology, Massachusetts, Boston showed that oocyte formation takes place in ovaries of reproductive-age women.[clarification needed] This report challenged a fundamental belief, held since the 1950s, that female mammals are born with a finite supply of eggs that is depleted throughout life and exhausted at menopause.
I wonder if that was from MIT or Harvard.
