Progesterone ni progestogene ikomeye, ya hormone steroid, ifite uburemere bugereranije bwa 314.5.Ikorwa cyane cyane na corpus luteum ya ovary na plasita mugihe utwite.Nibibanziriza imisemburo ya testosterone, estrogene na adrenal cortex.Urwego rwa progesterone rwakozwe mugihe cyicyiciro cyigitsina gabo nigitsina gore gisanzwe ni gito cyane, nyuma yo gusohora mumaraso, ahanini iba ihujwe na albumin na hormone yimibonano mpuzabitsina ihuza poroteyine kandi ikazenguruka mumubiri.

Igikorwa nyamukuru cya progesterone nugukora nyababyeyi yateguwe mugutera amagi yatewe no gukomeza gutwita.Mugihe cyicyiciro cyimihango, progesterone iba mike.Nyuma yintanga ngore, progesterone ikorwa na corpus luteum iriyongera vuba, kandi igera kuri concentration ya 10ng / mL-20ng / mL muminsi 5-7 nyuma yintanga.Niba udatekerejwe, corpus luteum atrophies muminsi ine yanyuma yimihango kandi progesterone yibanze igabanuka kugeza mugice cya follicular.Niba utwite, corpus luteum ntishira kandi ikomeza gusohora progesterone, ikagumya kurwego ruhwanye nicyiciro giciriritse kandi igakomeza kugeza icyumweru cya gatandatu cyo gutwita.Mugihe cyo gutwita, insimburangingo ihinduka buhoro buhoro isoko ya progesterone, kandi kwibanda kwiyongera kuva 10ng / mL-50ng / mL mumezi 3 yambere yo gutwita bikagera kuri 50ng / mL-280ng / mL mumezi 7-9.Ubushakashatsi bw’ubuvuzi bwerekanye ko progesterone igira uruhare mu guteza imbere intanga ngabo no gukomeza imikorere isanzwe ya corpus luteum ku bagore badatwite.Niba progesterone ikorwa na corpus luteum idahagije, irashobora kwerekana imikorere ya corpus luteum idahagije, kandi imikorere ya corpus luteum idahagije ifitanye isano n'uburumbuke no gukuramo inda hakiri kare.
