More and more evidences have shown that these two diseases have important effects on reproduction， being manifestated as infertility and spontaneous abortion clinically， especially abortion in the first trimester. The main causes of spontaneous miscarriage induced by endometriosis are endocrine dysfunction， decreased endometrial receptivity and immune factors. The mechanisms of spontaneous miscarriage caused by adenomyosis are damaged uterine spiral artery remodeling and abnormal structure and function of uterine junction zone. We should pay attention to the screening and diagnosis of endometriosis and adenomyosis in patients with spontaneous abortion， and active treatment is recommended before next pregnancy.
