title: [Changes of seminal parameters, zinc concentration and antibacterial activity in patients with non-inflammatory chronic prostatitis/chronic pelvic pain syndrome].
abstract: OBJECTIVE
  To investigate the seminal parameters, zinc concentration and antibacterial activity in patients with non- inflammatory chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS).
  
  
  METHODS
  Seminal parameters, zinc concentration and antibacterial activity of seminal plasma were detected in 60 CP/CPPS patients and 20 normal men.
  
  
  RESULTS
  Statistically significant differences were found in the duration of semen liquefaction, sperm vitality, sperm motility, zinc concentration and antibacterial activity of the seminal plasma between the CP/CPPS and the control males ( P < 0.01). Zinc concentration was significantly correlated with the duration of sperm motility (r = 0. 272, P = 0.015) and antibacterial activity of the seminal plasma (r = 0.449, P < 0.01) in the CP/CPPS patients.
  
  
  CONCLUSIONS
  CP/CPPS has a significant negative impact on semen liquefaction, sperm motility and vitality, zinc concentration and antibacterial activity of seminal plasma. The antibacterial activity of seminal plasma is positively correlated with zinc concentration and sperm motility.
