After endometrial polyp surgery, it is recommended to take progestin-based drugs to prevent recurrence. The etiology of endometrial polyps is due to a large amount of estrogen acting on the endometrium, which causes the endometrial tissue to proliferate in a restricted manner and form polyps. The recurrence rate of endometrial polyps is very high because the cause is not removed after endometrial polyp surgery, the cause is ovarian dysfunction, high estrogen levels, local hyperplasia of the endometrium and the cause is not removed after polypectomy, so the recurrence rate of endometrial polyps is very high, after surgery it is recommended that a large amount of progestin can be used to promote endometrial shedding to avoid recurrence of polyps, and also It is also recommended to use a large amount of progesterone to promote the shedding of the endometrium to avoid the recurrence of polyps, and also to wear the Manned Ring to prevent the recurrence of polyps.
