title: [A clinical study of biological zinc for the treatment of male infertility with chronic prostatitis].
abstract: OBJECTIVE
  To evaluate the efficacy of biological zinc in the treatment of male infertility with chronic prostatitis (MICP).
  
  
  METHODS
  Thirty-eight patients with MICP were treated with biological zinc. The zinc concentration in the semen and the seminal parameters were tested before and after using biological zinc.
  
  
  RESULTS
  After treatment, the zinc concentration in the semen was increased markedly, and the semen liquefaction and the sperm motility were also improved in the patients who had received biological zinc supplementation as compared with those who had not (P < 0.05).
  
  
  CONCLUSIONS
  It is suggested that biological zinc has the effect of increasing zinc concentration in semen, and the supplementation of biological zinc for one of the effective methods for the treatment of MICP.
