Female: The follicles of the ovaries secrete estrogen, which helps regulate the menstrual cycle and the development of the secondary sex characteristics. The corpus luteum also produces progesterone, which stimulates growth of blood vessels in the endometrium for the implantation of a fertilized egg. Male: The interstitial cells of the testes secrete testosterone, which is essential for maturation of sperm and for development of the secondary sex characteristics.
Hormones from both sexes have been isolated and standardized and are used to treat conditions arising from an insufficiency of these hormones.
