Combined therapy with LHRH and HCG in cryptorchid infants.

In 238 boys with cryptorchidism, between the ages of 4 and 48 months, luteinizing hormone releasing hormone (LHRH) was administered as nasal spray 1.2 mg/day for 4 weeks. The nonresponders received human chorionic gonadotropin (HCG) 500 I.U. i.m. three times a week for 3 weeks. With the combined treatment 37.8% of testes descended into the scrotum. Testicular descent occurred more often in patients whose testes were located in a lower position. Histological findings indicated a reduction in the number and maturation of germ cells. A clear improvement of germ cells trophism was observed in boys hormonally treated and operated on before the 12th month of life. Early administered combined treatment with LHRH and HCG can be considered as a substitution of the gonadotropins insufficiency manifested by most cryptorchid infants in the first months of life.
