List of progestogens

Retroprogesterone derivatives Although an active progestogen, retroprogesterone is not medically used. 17α-Hydroxyprogesterone derivatives 17α-hydroxyprogesterone is inactive as a progestogen and is not used medically. The 19-norprogesterone derivatives gestonorone caproate (gestronol hexanoate), nomegestrol acetate, segesterone acetate (nestorone, elcometrine), and norgestomet are also derivatives of 17α-hydroxyprogesterone (see below). 17α-Methylprogesterone derivatives Although an active progestogen, 17α-methylprogesterone is not medically used. The 19-norprogesterone derivatives demegestone, promegestone, and trimegestone are also derivatives of 17α-methylprogesterone (see below). Other 17α-substituted progesterone derivatives 19-Norprogesterone derivatives Although an active progestogen, 19-norprogesterone is not medically used. ==Testosterone derivatives==

Testosterone itself does not have significant progestogenic activity. Testosterone is instead classified as an anabolic-androgenic steroid and is included here purely because it is the parent structure of this group of progestins. 17α-Ethynyltestosterone derivatives 19-Nortestosterone derivatives While nandrolone (19-nortestosterone) does have significant progestogenic activity, it is not used as a progestogen. It is instead classified as an androgenic-anabolic steroid and is included here purely because it is an important parent structure of this group of progestins. 17α-Ethynyl-19-nortestosterone derivatives Estranes 18-Methylestranes (13β-ethylgonanes) Other 17α-substituted 19-nortestosterone derivatives ==Spirolactone derivatives==

Although an active progestogen, SC-5233 (spirolactone) is not medically used. ==See also==
