The patient: weak sperm went to the Hubei People’s Hospital, and the Department of Reproductive Medicine to see, do a sperm routine on the prescription of drugs, in the absence of what tests want to know what tests to do to determine the cause of the Yangzhou Women’s and Children’s Hospital, Department of Traditional Chinese Medicine Qi Tianshou: Modern medicine believes that: spermatogenesis, that is, from the spermatogenic stem cells to the formation of highly differentiated and specific sperm, including mitosis, meiosis and sperm formation and a series of complex steps. Spermatogenesis is regulated by neuroendocrine regulation, spermatogenesis-related gene regulation, and local regulation of cellular interactions in the testis. Apoptosis of spermatogenic cells is closely related to spermatogenesis, and apoptosis of spermatogenic cells is also related to infection. The maturation of spermatozoa is influenced both by spermatozoa themselves and by the microenvironment of the epididymis. Factors affecting sperm motility include semen viscosity, pH, osmotic pressure, inorganic ions, pathogenic microorganisms (bacteria, viruses, mycoplasma, chlamydia, trichomonas infection, etc.), seminal plasma cytokines, antisperm antibodies, lipid and antioxidant systems, abnormal sperm tail structure, protease deficiency, PGE and PGF2α, chromosomal abnormalities, endocrine hormones, varicocele, chemical toxins, smoking Alcohol consumption, drugs, physical factors (temperature, ionizing radiation, radiofrequency radiation, infrared radiation, laser, direct current, ultrasound, external shock waves), chemical factors (metals and their compounds, many organic compounds), etc. From the above, we can know that there are very complex factors, but it can be summarized into two aspects: factors that affect sperm production and factors that cause sperm damage, so the treatment is not only from these two aspects to start. The first thing you need to do is to check for mycoplasma, chlamydia and anti-sperm antibodies. Other aspects also please self-protection
