After hysteroscopic surgery for endometrial polyps, some contraceptive pills can be taken after the pathology has yielded a benign result. The role of contraceptive pills is to inhibit endometrial hyperplasia and thus prevent endometrial recurrence. You can also take some progestin-based medications such as progesterone. Progestins also inhibit endometrial proliferation, while it allows the endometrium to transform from the proliferative phase to the secretory phase, thus achieving a dry endometrial shedding and thus preventing recurrence.
