This is a rare abnormality in which the testis descends to an abnormal location, which is outside the normal route of descent, eg, the pubic region, thigh or perineum. The factors responsible for the production of this anomaly are unclear. It has been suggested that a part of the gubernaculum passes to an abnormal location and the testis follows it. Like the undescended testis, an ectopic testis also fails to produce spermatozoa and has an increased risk to develop cancer.
