I suggest you and your lover go to a specialist hospital for examination. The most basic examination items of female infertility are: 1, B-ultrasound examination of uterine appendix; 2. Do six sex hormone tests within three to seven days after menstruation is clean; 3. During ovulation (from the tenth day of menstrual period, once every other day, so that it can be done on the twentieth day of menstrual period), do B-ultrasound ovulation monitoring and inspection to see if there is follicular formation and follicular development; 4. Antibody examination. 5. Tubal lipiodol angiography (generally, you can not do it first, and then consider doing this examination after the above examination is normal. Most people who failed this examination have had a history of abortion). The man needs to have a semen test (abstinence for seven days).
