Physical characteristics that do not make it easy to get pregnant include polycystic ovary syndrome, endometriosis, and occupational lesions, but most infertile patients do not have special physical signs, as follows: 1. Polycystic ovary syndrome: Some infertile patients have special physical characteristics, such as excessive obesity, acne on the face, and hairy body. This condition, if accompanied by menstrual disorders, is often suspected of polycystic ovary syndrome and requires a Vaginal ultrasound and blood tests are needed to confirm the diagnosis. In polycystic patients, menstrual disorders are not easy to get pregnant because they do not ovulate, so they need ovulation treatment.2. Endometriosis: If the patient has severe dysmenorrhea, endometriosis is considered and pregnancy is not easy.3. Occupational lesions: If there is constant vaginal bleeding in the middle of menstruation, occupational lesions in the uterine cavity are considered and pregnancy is not easy, so hysteroscopy is recommended.4. Signs: Most of the infertile patients have no special signs, and both men and women need to go to the hospital together for examination. The male partner should check the semen, and the female partner should mainly take blood tests and do ultrasound, so that the doctor can determine what is wrong with both parties and give a treatment plan.
