How Do I Know If My Horse Is Cryptorchid?

Cryptorchid horses usually exhibit standard stallion behavior, but visibly/palpably lack one or both scrotal testicles. Immature horses may be undetected until they are examined just prior to routine castration. Mature horses with no detectable testes that behave like stallions may be a: Bilateral cryptorchid.

How do you tell if a horse is a cryptorchid?

A horse is considered to be a cryptorchid (also known as a rig or ridgling) if one or both testes are not fully descended into the scrotum. Cryptorchid testes may be located under the skin outside of the inguinal canal, within the inguinal canal or inside of the abdominal cavity.

How do you tell if a gelding is a cryptorchid?

Cryptorchid testicles can only be identified by palpation. FALSE. Three ways to check whether a horse you thought was a gelding is really a cryptorchid are rectal palpation, transrectal ultrasound and hormone challenge testing. Espy prefers the hormone challenge test.

How do you test for cryptorchidism?

Unfortunately, there’s no test, such as an ultrasound, that can definitively show whether a testicle is there. Surgery is the only way to find out for sure. Pediatric urologists are experts in both open and laparoscopic surgery.

How common is cryptorchidism in horses?

Cryptorchidism is defined as the failure of one or both testicles to descend into the scrotum. This condition is not uncommon in horses, and the retained testicle is usually located within the abdomen or inguinal canal. Monorchidism, or the condition of only having one testicle, is extremely rare in horses.

What does a cryptorchid horse look like?

Cryptorchid horses usually exhibit standard stallion behavior, but visibly/palpably lack one or both scrotal testicles. Immature horses may be undetected until they are examined just prior to routine castration. Mature horses with no detectable testes that behave like stallions may be a: Bilateral cryptorchid.

Can cryptorchidism go away on its own?

The vast majority of the time, the undescended testicle moves into the proper position on its own, within the first few months of life. If your son has an undescended testicle that doesn’t correct itself, surgery can relocate the testicle into the scrotum.

Can you geld a cryptorchid horse?

It is considered unethical for vets to remove only the external testicle in a cryptorchid horse, because the horse will continue to behave like a stallion and yet will appear externally to be a gelding.

How much does it cost to geld a cryptorchid horse?

First off is the cost of the surgery. Where a routine castration done standing or under general anesthesia may cost only a few hundred dollars, a cryptorchid surgery will be closer to $1,000 or more, depending on your approach and conditions.

What are the two types of cryptorchidism?

Types of cryptorchidism
Cryptorchidism is classified as “palpable” or “non-palpable”. A palpable undescended testicle can be felt on examination. A non-palpable testicle cannot be felt. Approximately 70% of all undescended testicles are palpable.

What happens if cryptorchidism is not treated?

If the testicles haven’t descended by 6 months, they’re very unlikely to do so and treatment will usually be recommended. This is because boys with untreated undescended testicles can have fertility problems (infertility) in later life and an increased risk of developing testicular cancer.

What is the most common place of cryptorchidism?

Cryptorchidism may occur on one or both sides but more commonly affects the right testicle. Bilateral cryptorchidism is present in about 10% of all undescended testicle patients. The testicle may be anywhere along the “path of descent,” including: High in the retroperitoneal abdomen close to the inguinal ring.

At what age is cryptorchidism?

Sometimes the testicles are in the scrotum at birth but are pulled up into the groin or abdomen at around 4-10 years of age. This happens because the cord that attaches the testicle to the abdomen doesn’t grow at the same rate as the child.

At what age should cryptorchidism be treated?

Treatment before 1 year of age might lower the risk of complications of an undescended testicle, such as infertility and testicular cancer. Earlier is better, but it’s recommended that surgery takes place before the child is 18 months old.

Does cryptorchidism hurt?

What are the signs of cryptorchidism? This condition is rarely associated with pain or other signs unless a complication develops. In its early stages, a single retained testicle is significantly smaller than the other, normal testicle. If both testicles are retained, the dog may be infertile.

How do I know if my horse is a rig?

A rig is an entire male horse with no signs of external testicles so appears to be a gelding; but one or two testicles are still present, producing testosterone. A rig behaves like a stallion and, potentially, may be fertile.

What is the most common risk factor for cryptorchidism?

The risk of cryptorchidism was found to be higher for low birth weight and premature infants but also for low parity, low social class, breech presentation, and preeclampsia. Weidner et al (1999) compared 6177 boys with cryptorchidism to 23 273 male controls born alive in Denmark from 1983 to 1992.

What is the difference between cryptorchid and Monorchid?

The correct scientific term is “unilateral cryptorchid.” A dog with both testes undescended would prop- erly be referred to as a “bilateral cryptorchid.” The scientific meaning of the word monorchid is a dog in which one testis is entirely absent and not simply retained in his abdomen or in the inguinal canal.

How do you fix cryptorchidism?

Orchidopexy. In most cases, if the testicle can be felt in the groin, a simple orchidopexy can be performed. This involves first making a cut (incision) in the groin to locate the undescended testicle. The testicle is then moved downwards and repositioned in the scrotum through a second incision.

What can cryptorchidism lead to?

Cryptorchidism, even if treated early and successfully, is expected to have long-term consequences⁷ such as reduced fertility, depression, and testicular cancer.

Is cryptorchidism life threatening?

Testicles in the scrotum are well anchored and the chance of the testicle twisting on itself is slim. Howe ever, in the abdomen, they may twist on themselves and cause obstruction to the normal blood flow. This can be painful and life threatening.
