In 10 adult male patients operated on for unilateral cryptorchidism, the testis was located in superficial inguinal pouch in 2 patients; intracanalicular in 5, and intraabdominally in 3 patients. Orchidopexy was performed on 8 patients; and orchiectomy on 2 patients for severe testicular atrophy. Normal spermatogenic function were found in 3 patients postoperatively. The best functional, anatomical, and cosmetic results were achieved in patients whose testis were located in the superficial inguinal pouch; while the worst results were found in intraabdominally located testis. A plea for early diagnosis and treatment of this entity in the tropics is reemphasized.
