NCT03838458

Brief Summary

The aim of this study is to compare prepuce tissue samples from healthy male children who applied for circumcision and children with isolated hypospadias. Estrogen receptor 1 (ER1), androgen receptor (AR), FGFR2, transforming growth factor beta (TGF beta) and HOXA13 gene expression in the prepuce is planned to investigate via polymerase chain reaction (PCR) method. Mucosal vascular and nerve densities, and extracellular matrix density of laminin and collagen protein is planned to investigate via immunohistochemical examination.
