This is a list of progestogens that are or that have been used in clinical or veterinary medicine. They are steroids and include derivatives of progesterone and testosterone.


== Progesterone derivatives ==


=== 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.
