Description

Author(s): Eric Chung, MBBS, FRACS, Gerald B. Brock, MD, FRCSC Cryptorchidism or undescended testis is one of the most common congenital conditions in the pediatric population. The prevalence of cryptorchidism in full-term newborns ranges between 1% and 3%, while in premature boys it is reported to be as high as 30%.[sup.1] Impairment of germ cell maturation and subsequent infertility in adulthood are well-recognized consequences of cryptorchidism. The incidence of azoospermia in unilateral cryptorchidism is 13% and this figure increases to 89% in untreated bilateral cryptorchidism, making cryptorchidism the most common etiologic factor of azoospermia in the adult.[sup.2] Reports have suggested that orchidopexy be performed before 1 year of age to minimize germ cell loss as fertility index (number of spermatogonia per tubule) is adversely affected in boys with cryptorchid testes beyond a year.[sup.3,4]
