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.
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 ...
Human reproductive biology is primarily controlled through hormones, which send signals to the human reproductive structures to influence growth and maturation.These hormones are secreted by endocrine glands, and spread to different tissues in the human body.
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 ]
Unlike the case of testosterone and estradiol, progesterone cannot be esterified as it lacks hydroxyl groups, so all progestogen esters, with the exception of esters of 17α-hydroxyprogesterone like hydroxyprogesterone caproate, are esters of progestins (synthetic progestogens) and are non-bioidentical.
