The male partner needs to check the semen routine, and the female partner needs to check whether there are normal follicles and whether they can be discharged normally by basal body temperature measurement, ovulation test paper or ultrasound. Next, we need to check whether the fallopian tubes are open bilaterally through tubal lavage or fallopian tube imaging, the thickness of the endometrium, and whether the endocrine condition is normal through sex hormone 6 test and thyroid function test. It is also necessary to screen for immune factors, gynecological internal examination, white belt routine, mycoplasma, gonorrhea screening, etc. It is recommended to go to a reproductive health center for detailed examination, step by step, to avoid frequent changes of hospitals, which cannot systematically understand the situation.
