Transverse testicular ectopia (TTE) is a rare congenital anomaly, in which both gonads migrate towards the same hemiscrotum. Other abnormalities such as persistent Müllerian duct syndrome, true hermaphroditism, inguinal hernia, hypospadias, pseudohermaphroditism, and scrotal anomalies may be associated with it.  Here we present the case of a 3 year old male child who presented with the complaint of a swelling in the right inguinal region since 3 months. Swelling increased in size on crying and coughing. On examination the child had a right inguinal hernia and the left side of scrotum was empty. Right testis was palpable separate from the hernia. Left testis was not palpable in the left side of scrotum or the left inguinal region. The child was planned for right herniotomy and left inguinal exploration. Intraoperatively, both testes were present in the right inguinal canal along with persistent Müllerian structures. The Müllerian structures were divided in the midline and the testes fixed in the respective scrotal sacs. Transverse testicular ectopia should be suspected in any patient with a nonpalpable undescended testis with contralateral inguinal hernia.
