What causes low sperm density?

Under normal circumstances, if the amount of fluid secreted by male prostatic fluid or seminal vesicle fluid is relatively large, or the amount of semen in one ejaculation is relatively large, the sperm density after semen dilution may be slightly lower, but if the total amount of sperm is within the normal range, it will generally not be affected. In addition, some disease factors can also affect testicular spermatogenesis, but also may cause low sperm count resulting in low density, such as mumps orchitis, varicocele, testicular trauma, and reproductive system infectious factors, such as prostatitis, epididymitis and other inflammatory infection factors, may also cause low sperm count, low sperm density. There are also factors such as drugs, drugs, alcohol and tobacco, etc., may also cause low sperm density. Expert tips: Male sperm density is low, usually due to semen diluted by seminal vesicle fluid, may also be caused by diseases, such as varicocele, mumps orchitis and so on.
