title: Role of Fas/FasL genes in azoospermia or oligozoospermia induced by testosterone undecanoate in rhesus monkey.
abstract: OBJECTIVE
  To investigate role of apoptosis related genes Fas/FasL in azoospermia or oligozoospermia induced by testosterone undecanoate.
  
  
  METHODS
  TUNEL was used to detect the apoptotic signal of testicular cells. Immunohistochemistry and Western blot were used to quantitatively or qualitatively analyze the expression of these apoptosis-related proteins.
  
  
  RESULTS
  After injection of testosterone undecanoate, both the apoptotic signal in germ cells and the expression of Fas/FasL in testis increased correlatively in a time-dependent manner, reaching a maximum level on day 30.
  
  
  CONCLUSIONS
  Fas system may initiate and regulate the germ cell apoptosis induced by testosterone undecanoate.
