What is Cryptorchidism

Cryptorchidism, also known as undescended testicles or retained testicles, is a medical condition that affects male cats (and other animals as well, including humans). In cryptorchidism, one or both of the testicles fail to descend from the abdomen into the scrotum, where they normally reside. This condition can be congenital, meaning the cat is born with it, or it can develop due to other factors.


Cryptorchidism is not directly transmitted from one cat to another. It is primarily a genetic condition. The inheritance pattern of cryptorchidism in cats is not fully understood, but there appears to be a hereditary component. Cats with a family history of cryptorchidism are more likely to develop the condition.


The main symptom of cryptorchidism is the absence of one or both testicles in the scrotum. The scrotum may be smaller or underdeveloped on the side where the testicle is missing. In some cases, the undescended testicle(s) can be palpated in the abdomen or inguinal canal (the pathway between the abdomen and scrotum).


Cryptorchidism can lead to several potential issues:

Overall, cryptorchidism in felines poses multiple health and reproductive concerns. It's crucial for cat owners and breeders to be aware of these issues and to consult with a veterinarian for proper diagnosis, management, and treatment if their cat is suspected to have undescended testicles.


The recommended treatment for cryptorchidism is surgical removal of the undescended testicle(s). This is both for the health of the cat and to prevent the potential transmission of the genetic predisposition for cryptorchidism.

Breeding and Genetic Considerations: 

Breeding cats with cryptorchidism is generally discouraged due to the hereditary nature of the condition. If a cat is known to have cryptorchidism, it's not advisable to breed it, as this can perpetuate the genetic predisposition for the condition in the bloodline.

Pros of Breeding this issue:

Cons of Breeding this issue:

Cryptorchidism in felines is a congenital condition where one or both testicles do not descend into the scrotum. It can lead to health issues and is often managed through surgical removal of the undescended testicle(s). Breeding cats with cryptorchidism is generally discouraged due to the hereditary nature of the condition and the associated health risks. Breeding out the gene has potential benefits but needs to be balanced with considerations of genetic diversity and breeding challenges.
