title: Polyorchidism diagnosed preoperatively by ultrasonography.
abstract: Polyorchidism, or multiple testes, is a rare condition that has been referred to in both medical literature and mythological folklore. Curious attributes have been ascribed to men with this condition, including supposed increased sexual prowess and virility. In the medical literature, the examples of supernumerary testicles have demonstrated only one additional testis. The first proven case of an extra testicle was by Lane, in 1895. Boggon reviewed 11 additional cases in 1933, and numerous other cases have been reported since then. To date, there has not been a preoperative ultrasonographic study that adequately describes this phenomenon.
