Results of combined hormonal and surgical treatment for undescended testis in boys under 3 years of age. A randomized study.

The effects of hormonal treatment (LH-RH, LH-RH plus hCG) on undescended testis were studied on 42 testicles in 37 boys under 3 years of age. Descensus was achieved primarily in 40% but eight testicles reascended. A new course of hCG resulted in descensus in three cases. Altogether, therefore, full descensus could be achieved in 29% of cases with hormonal treatment. Hormonal treatment is recommended before surgery.
