Progestin

(Redirected from Progestins)

A progestin is a synthetic progestagen. These particular synthetic hormones are most often used in the production of contraceptives.

Progestins are classified according to their structure in C19 and C21 progestagens. The C19 ones are derived from testosterone, the C21 ones from progesterone. C21 progestagens include cyproterone acetate, dydrogesterone, medroxyprogesterone acetate, chlormadinone acetate, megestrol and promegestone. Of these, dydrogesterone is structurally most similar to progesterone. C19 progestagens include norethisterone, (levo)norgestrel, lynestrenol, desogestrel, norgestimate, gestodene and tibolone.
