In clinical work, it is found that more than 90% of the infertility patients come for examination, and women are the ones who are examined and treated. In fact, among the infertility patients, male factors and the couple’s simultaneous illness account for most of the factors, and less than half of the infertility caused by female factors alone. Pregnancy is a joint effort of both husband and wife, not just for women. Many men are reluctant to go to the hospital for checkups due to various pressures. I came across a patient, the woman before and after spending nearly a year of examination and treatment, or no pregnancy, and then in my repeated reminders, finally mobilized their husbands to the hospital, a very robust man, complained that there was once a history of pregnancy with his ex-girlfriend, but the results of the semen test so that couples are surprised, the man is actually azoospermia, and then the man repeatedly recalled that there was a history of urethral secretion, they take The symptoms disappeared after taking a little medication, and no special attention was paid to it. Further examination confirmed that the man’s vas deferens was blocked. This case is quite special, but it shows that no matter how confident you are, you can’t say that you have normal fertility without concrete evidence, and it is relatively easy to check the male partner, so it is more important to take the initiative to check. Infertile couples must remember that infertility is not just a female cause and must be treated as a couple.
