Sperm survival rate is low what causes

Sperm survival rate is low for many reasons. Reproductive system infection can cause inflammation of the reproductive system, such as seminal vesiculitis, prostatitis, epididymitis, can cause semen abnormalities, such as pH, nutrition and other abnormalities can reduce sperm survival rate. Varicocele, due to venous reflux disorders caused by testicular hypoxia, and caused by prostaglandin, 5-hydroxytryptamine and other substances accumulation, will damage the seminiferous epithelium and testicular stroma; Varicocele can also increase scrotal temperature, which reduces sperm survival. Anti-sperm antibodies can cause sperm aggregation or immobilization, which reduces sperm survival. When testicular development is blocked, immature or damaged testicular spermatogenic epithelium and poor sperm quality are displayed. Zinc and selenium deficiency can cause sperm survival to be low.
