Three injections of human chorionic gonadotropin are as effective as ten injections in the treatment of cryptorchidism.

Two schedules of human chorionic gonadotropin (hCG) administration were compared in a study of 332 boys (473 testes) aged 1-13 years with cryptorchidism. One group of patients received 10 hCG injections according to the International Health Foundation (IHF) schedule while the other group received 3 hCG injections at intervals of 7-10 days (1-3 years = 3 x 1,000 IU; 3-6 years = 3 x 1,500 IU; 6-10 years = 3 x 3,000 IU; 10-13 years = 3 x 5,000 IU hCG). Results from both schedules were comparable during the first and also during a second treatment period at the age of 1-3 and 3-6 years; between 6 and 13 years of age the IHF schedule was more successful.
