Two consecutive abortions can cause damage to the endometrium and cause incomplete adhesions in the uterine cavity, resulting in decreased menstrual flow or the possibility of amenorrhea. In this case, even if the separation of adhesions is done under hysteroscopy, the adhesions are without endometrium and will become fibrotic, which is likely to lead to infertility. Therefore, for two consecutive abortions, it is recommended to observe the amount of menstruation after the operation. If the amount of menstruation is 1/3 less than before, it is likely to be caused by uterine adhesions. In addition, two consecutive abortions may cause bacterial infection, which may lead to inflammation of the pelvic cavity, inflammation of the endometrium, leading to tubal adhesions and causing infertility.
