When a woman is born, her ovaries contain a lifetime supply of eggs. Each month, follicle stimulating hormone (FSH) stimulates a group of eggs to mature within the ovary. In response, the ovarian follicle produces estrogen, the principal sex hormone that regulates female reproductive organs. Some women with ovarian factor infertility experience a decline in egg quantity and quality long before they hit menopause, making it difficult for them to conceive.
