Progestogens, also sometimes written progestins, progestagens or gestagens, [1] are a class of natural or synthetic steroid hormones that bind to and activate the progesterone receptors (PR). [ 2 ] [ 3 ] Progesterone is the major and most important progestogen in the body.
This is a list of progestogens that are or that have been used in clinical or veterinary medicine.
Progesterone (/ p r oʊ ˈ dʒ ɛ s t ər oʊ n / ⓘ; P4) is an endogenous steroid and progestogen sex hormone involved in the menstrual cycle, pregnancy, and embryogenesis of humans and other species. [1] [13] It belongs to a group of steroid hormones called the progestogens [13] and is the major progestogen in the body. Progesterone has a ...

Other contexts will include progestogens as a third class of sex steroids, distinct from androgens and estrogens. [5] Progesterone is the most important and only naturally occurring human progestogen. In general, androgens are considered "male sex hormones", since they have masculinizing effects, while estrogens and progestogens are considered ...
Prolactin and insulin-like growth factor binding protein are two examples of the hormones and growth factors that relaxin can stimulate the secretion of. [21] Preprorelaxin is the collective term for the signal peptide , B chain, C peptide, and A chain found in the coding area of human relaxin genes. [ 22 ]
Progestogens are used alone or in combination with estrogens. [1] They are available in a wide variety of formulations and for use by many different routes of administration. [1] Examples of progestogens include natural or bioidentical progesterone as well as progestins such as medroxyprogesterone acetate and norethisterone. [1]
