Is a Monorchid fertile

If the testicle is descended into the scrotum and is structurally and functionally normal, then a monorchid is fertile. However, the semen quality and quantity may be low. If a monorchid animal is to be used for breeding purposes, a semen exam should be performed routinely to ensure the animal is performing as expected. There is also a a slight concern that monorchidism could be hereditary; cryptorchidism (undescended testicle/s) is moderately inherited.
