Urotropin is a postmenopausal gonadotropin. It can promote the body to produce follicle-maturation hormone, promote the development and maturation of female follicles, prompt the follicles to secrete estrogen, cause the endometrium to proliferate, and then increase the chances of female ovulation, which has a good therapeutic effect on the treatment of female infertility. Because of its ability to promote endometrial proliferation, it can be used to treat female amenorrhea. Urotrophin can promote the development of male testicular sperm ducts, promote spermatopoietic cell division and sperm maturation, thus improving male sperm quality, and has good therapeutic effects on male oligospermia and weak spermatozoa. However, the side effects are large and some patients may experience nausea, vomiting, ascites, fever and other symptoms after application, and in serious cases, ovarian rupture and uterine bleeding may also occur, so patients should use it under the guidance of regular doctors.
