title: [Molecular epidemiologic investigation of infertile male's semen infected by Gardnerella vaginalis].
abstract: OBJECTIVE
  To investigate the status of the semen of the infertility patients infected by Gardnerella vaginalis (Gv).
  
  
  METHODS
  Semen samples from 373 clinic patients of infertility and vaginal samples from 63 positive patients' wives were collected from April 2002 to May 2003. And the samples were tested by nested polymerase chain reaction (nPCR).
  
  
  RESULTS
  The positive rate of the infertile males' semen infected by Gv was 44.2%, while that of the postive patients' wives was 87.3%.
  
  
  CONCLUSIONS
  The positive rate of the infertile male's semen infected by Gv is high and Gv can be spread by sexual intercourse.
