The prevalence of retained testes in Dunedin

Abstract

A cohort of approximately 500 boys was screened for retained testes at ages five and seven years and when the boys were aged three, five, seven and nine years, their parents were questioned about hospitalisation for surgery. Orchidopexy for retained testes had been performed on 15 of the 536 boys (2.8%) while one other had orchidopexy for high retractile testes (0.2%). Eighty-one percent of this surgery was performed between the seventh and ninth years of age.
