Transverse testicular ectopia (TTE) is an extremely rare congenital anomaly in which both testes descend through the same inguinal canal. We report an 8-month-old male with TTE and hypospadias. To help manage the patient, we conducted laparoscopy to elucidate the anatomy of the spermatic cord of the ectopic testis. On laparoscopy, we clearly identified the spermatic cord of the right ectopic testis. In addition, the laparoscopic guide was helpful when doing the trans-septal orchidopexy, in that the ectopic testis could be precisely discriminated without confusion as to the laterality of the testes. Long-term follow-up at 32 months confirmed that both testes were properly positioned in the scrotum and had a good consistency.
