Comparison of FGF-8, FGF-10, FGF-Receptor 2, Androgen Receptor, Estrogen Receptor-A and SS in Healthy and Hypospadiac Children

Abstract

Abstract In this study, we aimed to investigate the levels of Fibroblast Growth Factor-8 (FGF-8), FGF-10, FGF-Receptor-2 (FGFR-2), Androgen receptor (AR), Estrogen receptor alpha and beta (ER-α and ER-β) in the foreskins of children with and without hypospadias. Methods Samples from the foreskins of 20 children with hypospadias and 20 skin samples from children without hypospadias between the ages of 14 months and 12 years were taken during circumcision or hypospadias correction surgery for immunohistochemical (IHC) examination of these markers. In IHC examination, it was shown that ER-α, ER-β and AR receptors were more involved in the foreskin of children with hypospadias than in the fore-skin of without hypospadias children, and FGF-8, FGF-10 and FGFR-2 were lower (p<0.05). ER and AR uptake were higher in hypospadias tissue samples and FGF-8, FGF-10, and FGFR-2 uptakes were lower compared to without hypospadias children’s tissue samples, and these factors were supported by affecting each other in the development of hypospadias. The limited number of studies on this subject in the literature and the contradictory results of the findings indicate that more research should be done on this subject in the future.
