Endometrial polyps can be treated with progesterone, a natural progestin. For small endometrial polyps, progesterone capsules can be started before the onset of menstruation, i.e. during the luteal phase, and after stopping the medication, the endometrium is allowed to be completely exfoliated, i.e. medically scraped. Some small endometrial polyps will be expelled along with the endometrium, but for large endometrial polyps, progesterone often has no significant therapeutic effect, but can be used to adjust the menstrual cycle, usually large endometrial polyps need to be removed through hysteroscopic surgery, and after removal, progesterone can be used in conjunction with the entire menstrual cycle, through progesterone can inhibit the endometrial Progesterone can inhibit the recurrent proliferation of endometrial polyps, thus inhibiting the recurrence of endometrial polyps and achieving a therapeutic effect, and is often used to prevent the recurrence of polyps after endometrial polyp surgery.
