Penile anthropometry in Brazilian children and adolescents Avaliação das medidas do comprimento peniano de crianças e adolescentes

Objective: Classically, the penis has two functions: to make internalfertilizationpossibleandtodirecttheurinestream.However, objective abnormalities in penis size can lead to diseases being diagnosed. Furthermore, many medical consultations are the result of patients seeking parameters for normal penis size. Additionally, the penile anthropometry of Brazilian children and adolescents has not yet been properly studied. The objective of this study is to carry out penile anthropometry of Brazilian children and adolescents, establishing references for clinical use. Methods: A cross-sectional study was carried out of 2,010 patients with ages varying from 0 to 18 years. Five penile measurements were taken: diameter of penile shaft; apparent and real length of flaccid penis; apparent and real (RSLmax) length of flaccid penis fully stretched. Pubertal development was defined according to Tanner’s criteria. Results: Only RSLmax, out of all of the penile measurements, didnotexhibitsignificantinterobservervariationatallagesanalyzed (p=0.255).ResultsweretabulatedwithmeanRSLmaxandthevalues
