Chronic prostatitis reduces plasminogen activator (PA) system components in semen. While PA levels decrease, this reduction alone does not cause male infertility, suggesting PA may indicate prostate function.

Area of Science:

  • Urology
  • Reproductive Medicine
  • Biochemistry

Context:

  • Chronic prostatitis is a common condition affecting men's reproductive health.
  • The plasminogen activator (PA) system plays a role in various physiological processes, including reproduction.

Purpose:

  • To investigate the impact of chronic prostatitis on the expression and activity of the plasminogen activator (PA) system in semen.
  • To determine the relationship between PA system alterations and male infertility in chronic prostatitis patients.

Summary:

  • This study analyzed semen from 23 normal fertile males and 80 chronic prostatitis patients (40 fertile, 40 infertile).
  • Researchers measured total PA, tissue PA (tPA), and urokinase-type PA (uPA) using SDS-PAGE and fibrin overlay.
  • Results showed decreased PA, tPA, and uPA in chronic prostatitis patients compared to normal males, but no significant difference between fertile and infertile prostatitis groups.

Impact:

  • Chronic prostatitis impairs prostate secretory function, reducing PA synthesis and secretion.
  • Decreased PA levels alone do not cause infertility.
  • The PA system in semen may serve as a biomarker for assessing prostate function.
