OBJECTIVES: This prospective study aimed to investigate the expression of the androgen receptor(AR) and the estrogen receptor-β (ER-β) in foreskint issues in boys with and without distal hypospadias.
METHODS: Thirty boys with distal hypospadias were evaluated. Fifteen boys who under went elective circumcision over a period of 18 months served as the control group. The presence of AR and ER-β in foresk in tissues was investigated immunohistochemically.
RESULTS: The percentages of AR in epithelial cells were18.9 ± 27.3% in the hypospadias group and 3.3 ±5.3% in the circumcision group, and the difference betweent he groups was significant (p=0.034). Of the stromal cells, 19.5 ± 26.8% in the hypospadias group and2.6 ± 4.4% in the circumcision group were positive lystained for AR (p=0.004). In the hypospadias group,significantly higher stromal cell percentage of ER-β was found compared to that in the control group (24± 24.5% and 1.3 ± 1.1%, respectively, p<0.001). Moreover, epithelial cell percentage of ER-β was higher in the hypospadias group than that in the control group,and the respective values were 6.8 ± 10.1% and 0.9± 1.3% (p<0.0001)CONCLUSION: The percent of AR and ER-β expression were higher in hypospadias-affected foresk in than in the normal foreskin. Whether the normal function of these receptors reveals, there is a need for more detailed studies.
