The semen test is a routine examination for the male partner of an infertile couple. Generally, this test must be performed if no pregnancy has occurred for more than one year after marriage without contraception, in order to understand the amount of the male partner’s semen, the number of sperm, the survival rate of sperm, the activity rate and the normal morphology of sperm, etc. In our years of infertility treatment, we have found that many patients have the following misconceptions about semen examination. The first misconception: The male partner is healthy, so semen examination does not need to be done. The first misconception is that the male partner is healthy and the semen test is not necessary. Influenced by traditional feudal thinking, the husband always blames his wife for not being able to give birth to a child. Therefore, there are many infertile couples treated for many years, but it is always the woman in the hospital running around, the man does not want to do the most basic examination. The second misconception: if the semen test results are normal, it is the woman’s problem. In the outpatient treatment, there are many husbands who are waiting for the semen test results with apprehension, and once they are told that the indicators of this lab result are within the normal range, they will be long relieved to tell their wives: “I am fine, that is your problem!” This kind of either/or judgment is actually another misconception, because normal semen test results do not mean that you can have children. The results of routine semen examination can only give a general idea of the amount, smell, color, liquefaction time and the number, motility, activity rate and morphology of the sperm in the semen, but the normal internal structure of the sperm, the fertilization ability and the integrity of the genetic material are not known. In other words, we can only know the “external image” but not the “internal quality” of the sperm. In addition, about 10% of all infertile couples have unexplained infertility, where all the tests available to the couple are normal, but they are unable to conceive. Some couples divorce because they cannot have children, and when he or she marries again, it is easy to get pregnant again. Therefore, if the semen test results are normal, after the female partner has undergone further tests, and if they are basically normal, then the male partner has to undergo further tests. The third misconception: one routine semen examination is all that is needed. It is often found in male clinics that some patients are anxious to know whether their situation is good or not and whether they can make their female partner pregnant after they get their first routine semen test report. In fact, it is too early to draw a conclusion at this point. We know that the condition of a man’s semen is greatly affected by other factors, such as the interval between the semen extraction and the last ejaculation, the presence of sauna 2 weeks before the semen extraction, the presence of drugs that affect sperm vitality, the personnel and machines used for the examination, and other factors. Therefore, a single semen examination sometimes cannot fully and correctly reflect the true condition of semen. For this reason, the World Health Organization specifically requires that a routine semen examination be performed more than 2 times in a row within 2 weeks before a diagnosis can be made based on the results. Therefore, we should not jump to conclusions after getting the report, especially if the results are abnormal, sometimes it takes 3 times in a row before we can make a definite diagnosis.
