What causes incomplete sperm liquefaction?

After normal semen is ejected from the external orifice of the penis urethra, it quickly becomes a gel-like gray-white substance. Generally, after 15-30 minutes, semen will produce an automatic liquefaction process, which will make semen liquefied into a thin, flowing liquid. If it fails to completely liquefy within 60 minutes, it is called incomplete semen liquefaction. There are many reasons for this, and the most common is chronic prostatitis. Because prostatitis patients secrete prostatic fluid, proteolytic enzymes and plasmin activating factor reduced, the secretion of these two substances can directly cause semen is not completely liquefied. In addition, prostate tuberculosis can also cause semen is not completely liquefied, this is mainly due to tuberculosis of the destructive force, can destroy prostate acinar tissue and can cause obstruction of prostate duct, directly cause prostate fluid secretion reduced. When the human body lacks certain trace elements such as zinc and selenium, it can directly reduce the function of the prostate gland, causing the secretion function of prostatic fluid to decrease, thus causing incomplete liquefaction of semen.
