The main reasons for male sperm survival are as follows: i. Infection of the reproductive system, which can lead to inflammation of the reproductive system, such as prostatitis, seminal vesiculitis, epididymitis, urethritis, all these inflammatory diseases can cause variation of the semen, so that the acidity of the semen, the supply of oxygen, nutrient metabolism and so on are not conducive to the survival of sperms; ii. Varicose veins of the spermathecal veins, which cause hypoxia due to obstacles to venous return on one hand, and on the other hand, due to the backflow of the varicose vein and Prostaglandins and 5-hydroxytryptamine flowing into the renal venous blood of the testis can cause damage to the spermatogenic epithelium of the testicular varicocele and testicular mesenchyme, which can reduce the spermatogenic function and androgen production function of the testis; Third, the production of anti-sperm antibodies. Anti-sperm antibodies are a defense produced by men themselves, causing the immune system to produce antibodies that cause sperm to gather or brake, making it difficult for sperm to be produced and leading to a low sperm survival rate. Low sperm survival rate can be caused by one or more reasons, and it is important to identify the cause of the disease and treat the cause of the disease for better treatment.
