What are the reasons for the formation of dead sperm?

Patient's question:

What are the reasons for dead sperm? My sister and brother-in-law were high school classmates and had always had a very good relationship. However, after getting married for several years, they couldn't have children. Later, they were diagnosed with dead sperm syndrome. After learning about it, my brother-in-law felt he was burdening my sister and considered divorcing her many times, but my sister refused. What are the reasons for dead sperm? How should it be treated?

Doctor's answer:

Epididymitis refers to a decrease in sperm viability, with dead sperm accounting for more than 40%, or even most of the sperm in the semen being dead, resulting in a sperm survival rate of 0. The causes of epididymitis include:
1. Inflammation of the sexual reproductive organs can cause congestion and edema in the reproductive organs, blood stasis, and ischemia and hypoxia, leading to sperm death.
2. In chronic seminal vesiculitis, fructose secretion decreases, resulting in sperm death.
3. In testitis, epididymitis, or prostatitis, especially chronic prostatitis, secretion is affected, and trace element zinc levels decline, which can impair sperm metabolism and cause death.
It is recommended that you undergo timely examination to confirm the condition and receive targeted, effective treatment. Wishing you good health!
