Due to the influence of traditional thinking, when a couple cannot have children, many people first think that it is because of the female partner, and as long as they can have a normal sex life, they take it for granted that the male partner is fine (fertile), especially in rural areas where such thinking is deeply rooted. However, this is not the case. Some of the couples who came to our department have not been pregnant for a long time, and the female partner found some problems elsewhere, after which she has been testing ovulation and checking the fallopian tubes, and still not pregnant, and asked the female partner how her lover’s semen was, and the result said that the male partner had not been checked, and that the male partner was fine. In some cases, the male partner has to check the semen routine first (some men go to check it very reluctantly), and the semen result comes out to be of poor quality, which leads to a detour in the treatment of infertility. There are several other cases where it is easy to ignore the routine semen check for the male partner: 1. The two of us had children before and are preparing to have children again, but the female partner has abnormal menstruation and thinks that the male partner must be fine because he has had children. 2, the female party found out the problem has been under treatment, the male party a few years ago checked the semen is normal, did not timely review. 3, the man and his ex-wife have children, and after remarriage do not get pregnant, thinking that it must be the woman’s problem and the man is fine. In fact, the fertility of the male partner is very fragile, reproductive tract infections, environmental pollution, food additives, radiation, tobacco and alcohol, sedentary, obesity, high temperature, irregular life, etc. can all cause a decline in sperm quality, which can have a great impact on semen for several years or even months. Several of our patients had a child who was 7 or 8 years old and was ready to have another child, but the semen test turned out to be azoospermia. This is why the male partner should also have his semen checked regularly during the female partner’s long-term visits. The female partner has to monitor ovulation and check the fallopian tubes, which are both painful and costly, while the male partner has to check the semen, which is simple and less costly, so the male partner should be allowed to check the semen routine first and regularly.
