Oligospermia itself has no obvious symptoms and is often detected when a married couple seeks medical attention for infertility. Symptoms may occur when there is an associated disease that causes a decrease in sperm count. For example, in the case of varicocele, there may be scrotal swelling; in the case of prostatitis, there may be incomplete urination and swelling in the lumbosacral region; in the case of vesiculitis, there may be hematospermia; and in the case of orchitis, there may be testicular pain. For people with spermatogenic disorders, sperm count may be affected by various objective factors, and the same individual may have different results at different times and under different circumstances. These influencing factors include test error, duration of patient abstinence, physical condition, and mental factors. Therefore, it is still necessary to retain specimens for a certain interval of time (usually 3-7 days). And there should be more than 3 consecutive examinations before a conclusion can be made. At the same time, when judging the fertility of the patient, the sperm viability, sperm motility, sperm malformation rate and other indicators should be considered together to avoid misdiagnosis. To make the semen test results true and reliable, we must pay attention to the method of semen collection, the temperature of the environment where semen is kept, the time after ejaculation and other influences. All these factors can cause changes in sperm count, survival rate and activity rate, resulting in inaccurate lab results.
