In women of childbearing age, if there is irregular intrauterine bleeding, after diagnostic scraping, intercourse should be allowed only 7 days after the bleeding has stopped. In case of endometrial thickening, endometrial polyps and other uterine pathologies, diagnostic scraping is performed to clarify the diagnosis, and the endometrial tissues are scraped out and sent for pathological tests to stop the bleeding and clarify the diagnosis. After the scraping procedure, anti-blooding and anti-infection drugs are given and the bleeding usually stops within 3 to 7 days. Sexual intercourse is not allowed until 7 days after the bleeding has stopped. If you have intercourse after scraping with vaginal bleeding, it may lead to infection in the uterine cavity. In conclusion, diagnostic scraping is a common diagnostic method for gynecological diseases. Before and after scraping, it is important to follow the doctor’s instructions for preoperative preparation and postoperative care.
