A cryptorchid is a stallion that does not have two testes palpable in the scrotum because they didn’t descend through the inguinal rings. These stallions are even more difficult to handle compared to normal stallions.

Surgical removal of a cryptorchid testicle is called cryptorchidectomy. 

Most undescended testis can be easily removed by a minimal invasive inguinal approach by experienced surgeons. In more complicated cases, a laparoscopic cryptorcidectomy can be performed in the standing sedated horse
