Dr. Sitruk-Ware shares how the hormones estrogen and progesterone interact in women.

Dr. Sitruk-Ware:
Estrogen is the key hormone that leads to the development of the breast, the increasing growth of the urogenital tract, which means the vagina, the uterus, and improve the skin aspect, the hair growth. There are estrogen receptors in many parts of the body, also in the vessels, in the bone, in brain, and the progesterone is the hormone which is secreted when an ovulation takes place and when the women are during their fertile years, they have every month, an ovulation and a secretion of progesterone 15 days per month.

This hormone balances the estrogenic action on the uterus, on the breast, on the brain, on the vessels. They are two complementary hormones, and they are balancing each other. Estrogen is the hormone of tissue growth, and progesterone is a hormone of differentiation of the tissue to make it functional. For example, for the breast to have all of the ducts developed in terms of preparation for lactation as an example. So these two hormones are needed for the balance of all the tissues in the body of the woman.
