Normative data for penile length in Turkish Newborns

Background: local normative data for penile size will aid physicians in clinical practice. there are no studies on stretched penile length (spl) in newborn turkish boys. objective: to establish normative data for spl of newborn turkish boys and compare these with data from different countries. methods: 514 newborn turkish boys,who were not small for gestational age (sga) or premature,were included in this cross-sectional study. spls of the newborns were measured by the same investigator. the correlations between spl and gestational age,weight,length,and head circumference were evaluated. results: the 3 rd percentile value for spl was found as 3.00 cm in these turkish newborns. positive correlations were shown between spl and height (r=0.240,p<0.001),weight (r=0.251,p<0.001),and head circumference (r=0.235,p<0.001). multiple linear regression analysis showed that spl positively correlated with height and head circumference (p=0.021 and p= 0.042,respectively). conclusions: this is the largest study on spl in newborns from our country. this normative data can be used in clinical practice for defining micropenis. © journal of clinical research in pediatric endocrinology.
