Polyorchidism is a rare congenital anomaly with less than 100 cases reported in the world literature. Several theories have been proposed regarding the genesis of polyorchidism, but the exact explanation is still not known. In majority of the reported cases, the patients are asymptomatic and have painless groin or scrotal masses. In others, it may present as maldescent or cryptorchidism or it may be discovered in relation to an indirect inguinal hernia, hydrocele, varicocele, epididymitis, and infertility, testicular malignancy in maldescended testis or testicular torsion. The majority have triorchidism and the supernumerary testis is most frequently found on the left side. In the present report, a rare case of Supernumerary testis was detected incidentally during orchidopexy for left undescended testis.
