Testicular function in patients with hypospadias associated with enlarged prostatic utricle.
Of 485 patients with hypospadias who underwent urethrography, enlarged prostatic utricles were found in 173 (35.7%). Utricles with a higher grade of enlargement were seen mainly in patients with a severe degree of hypospadias. Serum testosterone levels before and after 3 days' treatment with human chorionic gonadotrophin were determined by radioimmunoassay in 97 prepubertal boys with hypospadias and enlarged prostatic utricles. Lower levels of serum testosterone were found after hormonal stimulation in 22 patients with high grade utricular enlargement when compared with 5 controls and 75 patients with low grade enlargement; the difference was statistically significant. This finding supports the hypothesis that utricular enlargement may be due to androgenic insufficiency during the critical period of organogenesis.
