After abortion, women’s uterine lining will be damaged to different degrees. At this time, artificial medication is needed to make the injured uterine lining repair continuously, and after growing to a certain thickness, it will be peeled off and a new round of menstruation will occur. Deferiprone is a kind of luteinizing hormone, which can make the endometrium change from the proliferative phase to the secretory phase, and maintain for a period of time, so that the endometrium will continue to be repaired, thickened, and then peeled off, and menstruation will occur. After abortion, the endometrium will be too thin due to scraping and suction, and the application of dydrogesterone can make the endometrium repair and thicken well, and then it can be peeled off and menstruation will occur, avoiding the emergence of uterine adhesion and amenorrhea.
