Normal sperm percentage of 3.5% belongs to aberrant spermatozoa, which can be seen in environmental and physical factors, mycoplasma infection, varicocele and other etiologies, and can be resolved by general and surgical treatments. A normal sperm percentage of 3.5% may not only lead to male infertility, but also lead to miscarriage in female pregnancy and abnormal fetal development. Specific treatments are as follows: 1. Environmental and physical factors: Usually, you should quit smoking and drinking, avoid overwork and staying up late, avoid high temperature environment and exposure to more radiation. Oral arginine tablets and compound amino acid capsules can be used for nutritional treatment. 2. mycoplasma infection: clear presence of mycoplasma and other pathogenic infections, can use broad-spectrum antibiotic azithromycin and other treatment. 2. Varicose veins of the spermatic cord: such as microsurgical ligation of the spermatic cord vein, transperitoneal retroperitoneal high ligation of the internal vein of the spermatic cord, transinguinal high ligation of the internal vein of the spermatic cord, laparoscopic spermatic cord vein ligation and so on. After the decrease of normal sperm percentage, it is recommended to consult a specialist at a regular hospital to understand the cause and follow the doctor’s instructions for targeted treatment, so as to avoid misdiagnosis and wrong treatment.
