[Treatment by human chorionic gonadotropin in maldescended testes. (Synthesis of our experience)]

87 prepuberal children, 2-15 years old, 58 with unilateral and 29 with bilateral cryptorchidism, were treated intramuscularly with Human Chorionic Gonadotropin (HCG). HCG was administered in 16 children in single dose (5.000 IU/m2), in 11 children every other day for one week (3 x 1,500 IU) and in 60 children twice a week (2 x 1,000 IU) for 3-7 weeks. Treatment was successful in 31% of children. The most effective HCG dosage ranged between 10,000 and 14,000 IU (2 x 1,000 IU once a week for 5-7 weeks). The best therapeutic response was obtained in inguinal cryptorchid testes (39,3%), in unilateral cryptorchidism (34,5%) and in children aged 5-10 years (42,3%). The observed androgenic side effects (32%) subsided within 3-12 months after therapy suspension. The HCG therapy appears of particular value in cryptorchidism treatment. Surgical management is indicated in cases of true ectopic testes and after failure of HCG therapy.
