| So a surge of LH, FSH, and Estrogen are all needed to cause a release of eggs? |

A baby girl is born with 1-2 million primary oocytes in her ovaries (frozen in prophase 1). None, as you alluded to, develop after birth. At puberty, only about 300 000 are left. A small percentage of primary oocytes mature into eggs (secondary oocytes). The thousands of oocytes that do not mature will degenerate. All are basically gone by menopause.
If one is fertile for 40 years (i.e. age 13 to 53), then approximately 40 X 12 = 580 eggs would be produced in her lifetime.
The purpose of the fertility drugs in the "production of eggs" could otherwise be described as the maturation of primary oocytes into secondary oocytes which can undergo ovulation. |
