Introduction Testicular ectopia refers to abnormal positioning of testis, which includes a wide variety of variants. An ectopic testis is located off the normal path of male gonadal descent, unlike conventional undescended testis. Case presentation A 37‐year‐old man presented with the complaint of a palpable lesion in the scrotum. Magnetic resonance imaging of the scrotum revealed bilateral testes on the respective opposite sides of the scrotum with bilateral spermatic cords crossing under the base of the penis. Accordingly, he was diagnosed as “left‐right reversal of the testes within the scrotum.” In retrospect, the “palpable” lesion was thought to be the spermatic cords crossing above the testes. Semen analysis identified deteriorated sperm motility, suggesting possible male infertility. Conclusion This case of left–right reversal of the testes within the scrotum is probably a new variant of testicular ectopia that has never been reported.
