At present, it is not clear that several miscarriages can lead to infertility; in some patients, one miscarriage can lead to infertility. There are many causes of infertility due to miscarriage, such as infection after miscarriage, which can lead to inflammation of the uterus and obstruction of the fallopian tubes. In addition, it can also lead to endometriosis and the development of endometrial damage, all of which can cause infertility. The endometrium is like land, if the land is not fertile, the seeds cannot grow. Therefore, women who are not planning to have children should do a good job of contraception and eliminate the damage caused by multiple abortions.
