Progestin
medication Under reviewProgesterone is a natural steroid hormone produced primarily by the ovaries, adrenal glands, and placenta during pregnancy. It plays a central role in regulating the menstrual cycle by transforming the endometrium from a proliferative to a secretory state, preparing it for potential implantation of a fertilized ovum. Progesterone also suppresses uterine contractility, exerts antiestrogenic and antiandrogenic effects, and counterbalances estrogen to prevent endometrial hyperplasia. As a therapeutic supplement, it is available in forms such as oral micronized capsules, creams, and gels, often used to mimic or supplement endogenous levels in conditions involving hormonal imbalance.
Research summary
Scientific evidence on progesterone supplementation in healthy human subjects is limited and mixed, with small double-blind trials showing inconsistent benefits for menopausal symptoms like hot flashes and no reliable protective effect against estrogen-induced uterine changes at typical supplemental doses. Studies highlight its physiological roles in pain modulation, immune regulation, and reproductive health, but robust data from healthy populations is scarce, and larger trials are needed to establish efficacy and safety. Natural progesterone is distinguished from synthetic progestins, potentially offering a better side effect profile, though clinical outcomes vary.
