A synthetic or natural compound with progesterone-like activity used in contraception and hormone therapy.
Also known as: progestogen
Progestin is a general term for progesterone-like medications. Progestins are used in birth control and, in menopausal hormone therapy, to protect the uterine lining from estrogen.
Different progestins vary in their properties; micronized progesterone is the body-identical option in the same broad category.
