What causes undescended testicles in horses?

Cryptorchidism (Undescended Testicles) in Horses. A single cause of equine cryptorchidism has not been established and contributing causes remain obscure. The condition is likely the result of a complex combination of genetic, hormonal, and mechanical factors.

What does it mean when a horse has one testicle left?

If one or both of the testicles remain in the abdomen, the horse is said to be a rig, or ridgling. A stallion that is a cryptorchid should not be used for breeding, as it is suspected to be a genetic problem. The left testicle is more commonly retained than the right.

Should I castrate my horse with undescended testicles?

The complications of undescended testicles lead many veterinarians to recommend castration. If the abnormality is indeed genetic, castration could help to prevent further cases of undescended testicles in horses. Cryptorchidism in horses is a condition when one or both testicles fail to descend into the scrotum from the abdominal cavity.

Can a horse have one testicle and still produce testosterone?

In all cases of one undescended testicle, the stallion will still be able to produce normal amounts of testosterone. Usually, the undescended testicle is much smaller than the descended one. If one or both of the testicles remain in the abdomen, the horse is said to be a rig, or ridgling.

How do you find out if a horse has a missing testicle?

If one testicle is missing, this is easily palpated. Occasionally, the horse will need to be sedated for this procedure to be done safely. Once it has been determined that a testicle is not in the scrotum, the next step is to try to locate where it is. Rectal examination may help locate it if it has been retained high in the abdomen.

What is a Troy on a horse?
