Surgical Treatment of Unilaterally Undescended Testes: Testicular Growth After Randomization to Orchiopexy at Age 9 Months or 3 Years

Abstract

Surgical treatment at 9 months resulted in partial catch-up of testicular growth until at least age 4 years compared to surgery at 3 years, clearly indicating that early surgery has a beneficial effect on testicular growth. Since testicular volume is an approximate indirect measure of spermatogenic activity, this gives hope that orchiopexy at this age may improve future spermatogenesis.
