Transverse testicular ectopia is very rare. Recently, a 9-year-old boy was operated on for left undescended testis. At age of five, he underwent an exploration of the right side undescended testis. The right testis was not found. Monoorchism was the diagnosis at that time. At this operation, two testes were found in the left inguinal canal. The left testis was snugly placed in the right scrotum through the scrotal septal window. The left testis was placed in the scrotum in usual fashion.
