| Research Abstract |
Gonadal function at puberty in patients with hypospadias was retrospectively reviewed.Our study revealed endocrine dysfunction in patients with mild and severe hypospadias at puberty even without an undescended testis. Of these patients those with severe hypospadias and an undescended testis may be at higher risk for impaired spermatogenesis.2) Preoperative testicular volume was measured to evaluate the relationship to the severity of hypospadias. Testicular volume in patients with severe hypospadias was relatively smaller compared to that in patients with mild hypospadias. These results may indicate that gonadal function in patients with severe hypospadias was severely impaired compared to those with mild hypospadias.
