The most common treatment for luteal atrophy is to supplement the progesterone deficiency in the body, usually with intramuscular progesterone injections and oral progesterone in the ampulla, and also with chorionic gonadotropin to promote luteal function. I: Luteinizing hormone supplementation therapy. Starting from 8-10 days before the next menstruation, progesterone 20mg intramuscularly or progesterone 10mg orally is administered daily for 7-10 days. Its effect is to regulate the feedback function of the hypothalamic-pituitary-ovarian axis, so that the corpus luteum atrophies in time and the endometrium is shed more completely. Two: Chorionic gonadotropin. Usually chorionic gonadotropin is applied to promote and support luteal function. HCG 2000-3000 U is injected intramuscularly every other day for 5 times starting after the basal body temperature rises, which can lead to a significant rise in progesterone and the subsequent resumption of normal menstrual cycle.
