Penis size measurements in prepubertal children

The aim of this study is to evaluate abnormal penis length in children by establishing the reference values in Turkish population and to compare the mean penis length and other parameters with alternates from different ethnic populations and geographyComplete stretch penis length and midpenis circumference measurements were used for penis length and penis circumference evaluations, respectively. All measurements were done twice by only one investigator and mean values were recorded.General pediatry patients of Gazi University, students of two different primary schools, newborns of Etlik Zübeyde Hanım Doğumevi and Gazi University are the participants of our study. Prematurity, obesity, chronic disease and hypospadias were exclusion criterias for this study.In this cross sectional study, the relation of penis length and circumference with age, height, weight and height age of patient was investigated by Pearson correlation test. Single sample t test was used in order to compare the similarity of our study findings with the previous ones for penis length measurements. While composing reference percentage curves, LMS method with Penalized probability was used.Finally, normal values for penis length and circumference, percentile curves were established and these findings were compared with the results of previous studies. Significant differences were found between penis length of Turkish children and recently used reference values for evaluating penis length. Similar penis length values were detected in similar ethnic populations and children living in similar geography. With this study novel reference values for penis length in prepubertal children were presented to the literature.
