Testicular descent and ascent in the first year of life

Abstract:
Ascent of the intrascrotal testis to an undescended position has been described, but it remains controversial. A case of a 1-year-old with bilateral ascended testes is presented. These testes were documented by a pediatric urologist to have been intrascrotal on two prior occasions. The right testis was intra-abdominal, and the left was peeping at the internal ring. Ascent has generally been seen in older children with a history of retractile testis and has never been reported to result in a testis located in an intra-abdominal position. This represents a rarely reported early testicular ascent, the mechanism of which is different than that of older children.
