ABSTRACT

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-Beta 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-Beta 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
RESUMEN

OBJETIVO:

Este estudio prospectivo que pretende investigar la expresión del receptor androgénicoy estrogénico en la piel prepucial en niños con y sin hipospadias distal.

MÉTODOS:

Treinta niños con hipospadias distal fueron evaluados. 15 niños recibieron una circuncisión electiva en un periodo de 18 meses y sirvieron de grupo control.La presencia de RA y RE-Beta en la piel prepucial se investigó por immunohistoquimica.

RESULTADOS:

El porcentaje de expresión del receptor androgenico en células epiteliales fue de 18,9 +/- 27,3% en el grupo hipospadias y 3,3 +/- 5,3% en el grupo de circuncisión. La diferencia entre ambos grupos fue significativo (p = 0,034). En las células estromales,19,5 +/- 26,8% en el grupo hipospadias y 2,6+/-4,4% en el grupo circuncisión fueron positivos para el RA (p = 0,004). En el grupo de hipospadias, un porcentaje más elevdo de expresión de RE-b β se evidencio en comparación al grupo control (24 +/- 24,5%y 1,3 +/- 1,1, respectivamente, pel porcentaje de células epiteliales con RE-Beta fue superior en el grupo hipospadias que en el grupo control; los valores respectivos fueron 6,8 +/- 10,1% y 0,9 +/- 1,3%(p < 0,0001).

CONCLUSIÓN:

En este estudio se sugiere que la expresiónde RA y RE fueron superiores en el grupo conhipospadias que en piel prepucial normal. Se requierenmas estudios para determinar el significado de esta expresión
