Some patients have no clinical symptom; some might have symptoms of spermatorrhea, prospermia or lack of sexual desire; some might suffer from prostatitis, vesiculitis, orchitis and epididymitis. The patients would find the symptoms like orchialgia, perineum pain, abdominal pain, inguinodynia etc. They could take nomal semen test to identify the disease.

Necrospermia means that sperms are identified dead according to times of semen tests. Under normal circumstances, the sperms' survival ratio should be above 70% after semen discharged for one hour, if the dead sperms are more than 40%, it affect fertilization; the sperms' survival ratio should be above 20% in six hours, if no sperms are living after six hours, it will result in infertility. Fructose in seminal vesicle has immediate connection with sperms' status. If the fructose content reduces, nutriments will reduce, sperms death rate will go high. Certain amount of abnormal sperms is unavoidable, and we think it normal when the rate is under 10%. But when the rate is higher than 10% or even reach 20%, infertility will happen, usually accompanying with semen quality problems such as bad liquefaction and low vitality.
