Patient Education

Estrogen and Progestin (Hormone Replacement Therapy)


Combinations of estrogen and progestin are used to treat certain symptoms of menopause. Estrogen and progestin are two female sex hormones. Hormone replacement therapy works by replacing estrogen hormone that is no longer being made by the body. Estrogen reduces feelings of warmth in the upper body and periods of sweating and heat (hot flashes), vaginal symptoms (itching, burning, and dryness) and difficulty with urination, but it does not relieve other symptoms of menopause such as nervousness or depression. Estrogen also prevents thinning of the bones (osteoporosis) in menopausal women. Progestin is added to estrogen in hormone replacement therapy to reduce the risk of uterine cancer in women who still have their uterus.
