1, first check the husband: the male partner first do semen examination (about 100 yuan). If the semen test is normal, basically the male partner can be ruled out as the cause of infertility; if it is the husband’s problem, no need to check the wife again. 2, the female side of the examination follows the “progressive, demining method”: a, the first visit, do a general gynecological examination to see if there are reproductive organ abnormalities and vaginitis, uterine tumors and other gynecological diseases. If you have a disease, treat it first and then see if you can get pregnant; b. Next, check the endocrine, and at the same time, you can start ultrasound monitoring of egg cell growth and ovulation on the 13th day of your menstrual cycle; c. The third step is to check the fallopian tubes; if all the previous gynecological examinations are normal, you need to do a tubal lavage test 3 to 5 days after your period is clean, which is the easiest way. If there is a blockage in the fallopian tube, it needs to be treated to make it smooth; d. If the previous examinations are not found to be wrong, then check the immune problems such as anti-endometrial antibody and anti-sperm antibody.
