When uterine adhesion occurs after abortion, the part of endometrial adhesion can be removed and repaired through hysteroscopy, and at the same time, a large amount of progesterone can be used to avoid endometrial adhesion again, and adhesion can also be avoided through the intrauterine band of the birth control device. Repeated abortions may cause endometrial injury, and inflammation of tissues around the endometrium ooze out, causing endometrial adhesion. In addition, endometrial adhesion may cause decreased menstrual blood flow, irregular vaginal bleeding, and secondary infertility. Clinically, for endometrial adhesion, after separation by hysteroscopy, it can be treated with a large amount of estrogen and progesterone to improve endometrial adhesion, or it can be prevented by wearing a Mannix ring.
