title: Penile anthropometry of normal prepubertal boys in Turkey.
abstract: OBJECTIVE
  The age-related values of penile length must be known to determine abnormal penis sizes and to follow the treatment of underlying diseases. The aim of this study is to evaluate abnormal penile length in Turkish children by establishing novel reference values for Turkish population and to compare the mean penile length and other parameters with alternates from different ethnic populations and geography.
  
  
  METHODS
  This cross-sectional study was conducted on a voluntary basis between November 2008 and November 2009 from four centres in Turkey and comprised of 1278 healthy volunteered prepubertal children. Complete stretched penile length and penis circumference measurements were used for penile length and penis circumference evaluations, respectively. All measurements were taken twice by only one investigator, and mean values were recorded.
  
  
  RESULTS
  Penile length and penis circumference for every age group were obtained, percentile curves were established and these findings were compared with the results of previous studies. Significant differences were found between penile length of Turkish children and recently used reference values.
  
  
  CONCLUSIONS
  With this study, novel reference values for penile length in prepubertal children were presented to the literature.
