title: [Infection of Chlamydia trachomatis and apoptosis of spermatogenic cells].
abstract: OBJECTIVE
  To evaluate the relationship between infection of Chlamydia Trachomatis(Ct) and apoptosis of spermatogenic cells.
  
  
  METHODS
  Apoptotic spermatogenic cells were examined by Wright-Giemsa staining and the terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate(dUTP)-biotin nick-end labeling(TUNEL) technique.
  
  
  RESULTS
  Apoptosis rate of Ct infective group was significantly higher than that of normal group(P < 0.01).
  
  
  CONCLUSIONS
  Ct infection may cause the apoptosis of spermatogenic cells, which affords an objective evidence for illustrating the mechanism of Ct-infection-induced male infertility.
