Any one of the requirements are not met, can not be diagnosed infertility, that is, do not have to go to the hospital to see a doctor. If you meet the above diagnostic criteria, you should go to the infertility clinic. First of all, check your lover’s semen, if your lover’s semen is abnormal, please consult the male department for semen treatment; if your lover’s semen is normal, it is recommended to check gynecology, ultrasound, hormone level, basal body temperature, if they are all normal, uterine iodine-oil angiography should be checked; if the woman’s side has problems with the above tests, check and treat according to the needs, and hysteroscopy and laparoscopy and fluids are needed when necessary.
