Infertility caused by miscarriage may be related to endometrial damage and pelvic inflammatory disease and other complications, if it is caused by mild pelvic inflammatory disease, it is possible to cure. 1. Endometrial damage: it can cause symptoms of not having menstruation or having too little menstruation, and ultrasound monitoring during ovulation can observe that the endometrium is too thin, which generally suggests that the uterus is adherent to the uterus, which has a relatively big impact on fertility, and there is no particularly effective treatment for this kind of infertility caused by endometrial damage. 2. Pelvic inflammatory disease: it may cause tubal adhesion or tubal impassability and other symptoms, which will lead to infertility and have certain effects. If the symptoms of tubal impassability are more serious, it will also cause infertility; if the tubal impassability is relatively mild, it is possible to get pregnant. Infertile women are advised to go to regular hospitals for further examination and treatment according to the results.
