Androgens are important in the inguinoscrotal testicular descent in animals and humans. In general, the cause of cryptorchidism is unknown and the aetiology is possibly multifactorial. Histological changes in cryptorchid testes demons...

Forty boys with 54 incompletely descended testes took part in a double blind, controlled trial of intranasal luteinising hormone releasing hormone. In the control (placebo) group of 18 boys there was no significant change in testicular descent and all required orchidopexy; in the 22 treated boys, however, 12 of 29 testes (42%) were found in a lower position. This study supports the idea that a ...
