, which refers to the presence of three testes, is the most frequent presentation and the supernumerary testis is often located in the left side of the scrotum (2,3).
(1) The most common presentation is triorchidism
with intrascrotal left-sided predominance.
The majority of patients with SNT have triorchidism
with two testes in the scrotal sac .
As in the present case, left triorchidism was the most frequent presentation (65%), and the majority of supernumerary testes were found in the scrotal region (66%), followed by inguinal (23%) and abdominal (9%) locations.
Triorchidism: a case report and review of similar conditions.
Associated anomalies with polyorchidism includes inguinal hernia in 24%, cryptorchidism in 22% and testicular torsion 15% of cases.[sup.1] Amodio and colleagues reported a case of triorchidism
with co-existant microlithiasis,[sup.7] but to the best of our knowledge, there has not been a reported increase in the incidence of microlithiasis and polyorchidism.
Several terms have been used in the literature to describe an accessory or extra testis, including supernumerary testis,[sup.1]-[sup.3] polyorchidism,[sup.4]-[sup.13] testicular duplication,[sup.14,15] double testis[sup.16] and triorchidism.[sup.17]-[sup.19] Polyorchidism is rare, with less than 100 cases reported to date,[sup.5] and is more common on the left side.[sup.20] Polyorchidism has been associated with several conditions including testicular cancer,[sup.6,8] cryptorchidism,[sup.7]-[sup.15] inguinal hernia,[sup.13] hydrocele,[sup.13] infertility,[sup.13] varicocele[sup.1] and testicular torsion.[sup.9]-[sup.11] Testicular torsion is the most commonly reported associated condition.[sup.20]

, and, occasionally, bilateral duplication has been reported.
