Estrogen replacement therapy is prescribed primarily to relieve menopausal symptoms such as hot flashes. It has also become a popular measure for preventing osteoporosis and reducing the risk of heart disease.

It is approved for treating breast engorgement right after childbirth when a woman does not plan to breastfeed.

Estrogen can also be helpful in various conditions where a woman does not produce enough natural estrogen. Certain cancers in men and women may benefit from estrogen therapy.
