Indication: 1. To supplement the lack of estrogen and treat female hypogonadism, amenorrhea, menopausal syndrome, etc.; used for the treatment of advanced breast cancer (postmenopausal women) and advanced prostate cancer; used in combination with progesterone drugs, it can inhibit ovulation and can be used as a contraceptive. It is mainly used clinically as an ovulation inhibitor; it is also used for cryptorchidism and androgen excess in children, pituitary tumors, etc. It is used to diagnose hypothalamic-adenohypophysial-gonadal dysfunction, which can be based on changes in gonadotropin and sex hormone levels. 2. To treat amenorrhea and infertility caused by hypogonadism due to insufficient secretion of gonadotropin, and infertility of multifollicular ovary. For amenorrhea related to weight loss, the weight should be corrected by diet first. It is also used for prostate cancer (often used in combination with cyproterone acetate or fluazifop), delayed or early puberty, and endometrial dysplasia. Main
