Answer

Progestins

Progestins stop endometrial cell proliferation, allowing organized sloughing of cells after withdrawal. No long-term controlled studies compare efficacy of medroxyprogesterone with oral progesterone in protecting the endometrium from neoplasia at the doses of estrogen generally required for replacement in young women. The authors recommend use medroxyprogesterone as first-line therapy because of longer-term clinical experience with this agent.

Medroxyprogesterone (Provera, Cycrin, Depo-Provera, Amen)

Administer cyclically 12 d/mo to prevent endometrial hyperplasia that unopposed estrogen may cause. In young women, regular withdrawal bleeding is preferable because even young women with premature ovarian failure have a 5-10% chance of spontaneous pregnancy (unlike postmenopausal women). If an expected withdrawal bleeding is absent, perform a pregnancy test (and a timely diagnosis of pregnancy will not be missed). Other causes of amenorrhea may also remit spontaneously and result in an unexpected pregnancy.

Progesterone (Prometrium)

This agent is used to prevent endometrial hyperplasia
