Acquired Undescended Testis: Should Every Ascending Testis Be Operated On?

A previously scrotal testis is now persistently extrascrotal.Is orchiopexy always the correct next step?This episode examines one of the less settled areas in cryptorchidism: acquired undescended testis.We explore how acquired ascent differs biologically from congenital cryptorchidism, why previous documentation of scrotal position matters, and how relative cord shortening, persistent processus vaginalis remnants, and somatic growth may contribute to ascent.The central controversy is management.Some acquired testes descend spontaneously around puberty, yet histologic abnormalities and impaired fertility potential have also been described. The evidence does not clearly prove that immediate orchiopexy improves long-term fertility in every unilateral case.The practical problem is therefore not simply identifying ascent. It is deciding which child can reasonably be observed and which findings should trigger surgery.We discuss age, laterality, progressive proximal migration, cord tension, testicular asymmetry, pubertal development, and how to define an active surveillance strategy when observation is chosen.
