Sperm freezing is actually a symptom of sperm liquefaction. Sperm injected by patients are usually viscous or jelly-like, which will appear in flake, lump and lump, and will not liquefy in vitro for more than an hour.
Sperm does not liquefy because:
1. Reproductive tract infection: Acute and chronic inflammation of epididymis, vas deferens, seminal vesicle and prostate can reduce sperm motility. The influence of infection on sperm motility may be various;
2. Varicocele: Varicocele will destroy some structures of testis, affect the ability of testis to produce sperm, hinder sperm activity and reduce sperm survival rate;
3. Abnormal sperm liquefaction: Sperm liquefaction or high viscosity is one of the causes of sexual dysfunction, usually due to insufficient fibrinolytic enzyme secreted by prostate or lack of trace elements (magnesium, zinc, etc.). ). One of the most important factors is to reduce sperm survival rate by affecting sperm motility;
4. Chromosome abnormality: It may be caused by sperm and eggs losing a chromosome gene fragment in the process of forming fertilized eggs. Autosomal and sex chromosome aberrations not only affect sperm quantity, but also affect sperm motility and ability to move forward.
You'd better go to the hospital for a systematic andrology examination.
