Prospective Cohort Study on the Effect of Combined Estrogen and Progestogen Therapy on Endometrial Repair and Ovarian Function Recovery After Induced Abortion
Induced abortion is a common method to terminate pregnancy, but during the operation, it is necessary to dilate the cervix and aspirate the uterine cavity. Repeated induced abortions may increase the risk of uterine damage, leading to cervical stenosis or intrauterine adhesions, thinning of the endometrium, which may affect the implantation of fertilized eggs and the development of embryos, and ultimately may lead to infertility or miscarriage. This study aims to explore the effects of combined estrogen and progesterone on endometrial repair and ovarian function recovery after induced abortion.
