title: [Epidemiological study of external genital diseases in 5172 adolescents].
abstract: OBJECTIVE
  To study the incidence of external genital diseases and the health status of external genitalia in male adolescents in china.
  
  
  METHODS
  5172 male adolescents aged 7-22 were sampled randomly to examine the diseases and health status of external genitalia. According to the diagnostic criteria in textbook Surgery (3rd edition), all examinations were carried out by urologists.
  
  
  RESULTS
  The total incidence of redundant prepuce was 67.79%, phimosis 10.09%, varicocele 19.82%, hydrocele 0.87%, concealed penis 0.68%, cryptorchidism 0.39%.
  
  
  CONCLUSIONS
  The health status of external genitalia in male adolescents is bad. Redundant prepuce and phimosis are common diseases. The examination of external genitalia should be carried out in the physical examination of admission. This study may provide the theoretical evidence for prevention and treatment of male external genital disease as well as the important data for study on andrology.
