A progestin is a synthetic progestogen that has some biological activity similar to progesterone.
The two most frequent uses of progestins are for hormonal contraception (either alone or with an estrogen), and to prevent endometrial hyperplasia from unopposed estrogen in hormone replacement therapy. Progestins are also used to treat secondary amenorrhea, dysfunctional uterine bleeding and endometriosis, and as palliative treatment of endometrial cancer, renal cell carcinoma, breast cancer, and prostate cancer. High dose megestrol acetate is used to treat anorexia, cachexia and AIDS-related wasting. Progesterone (or sometimes the progestin dydrogesterone or 17α-hydroxyprogesterone caproate) is used for luteal support in IVF protocols, questionably for treatment of recurrent pregnancy loss, and for prevention of preterm birth in pregnant women with a history of at least one spontaneous preterm birth.
