ARRT Ultrasound Practice Test

Polyorchidism is defined by having more than two testes. This rare congenital condition, also called a supernumerary testis, occurs when an extra testicular bud forms during development and remains separate from the two normal testes. In imaging and clinical workups, you’d look for an additional testicular tissue that typically has a similar echotexture to normal testes and may have its own blood supply and tunica coverings. The defining idea is an extra testis beyond the usual two, rather than two, one, or no testes. The other scenarios describe normal anatomy (two), monorchism (one), or anorchia (none) and do not meet this definition.
