Cryptorchidism in cats is a congenital anomaly in which one or both testicles do not descend into the scrotum, but remain in the abdomen or inguinal canal.

The most important facts at a glance

Cryptorchidism in cats is a developmental disorder in which one or both testicles do not descend into the scrotum. Normally, testicle descent occurs in the first few months of life and is controlled by hormonal signals. Causes are often genetic, but can also be caused by hormonal imbalances or mechanical obstructions in the inguinal canal. Environmental factors such as certain medications or chemicals can increase the risk. Symptoms are usually a non-palpable testicle in the scrotum, sometimes also swelling in the groin area. Diagnosis is made by physical examination and, if necessary, ultrasound. Blood tests can assess testicular function. Treatment consists of surgical removal of the undescended testicle to reduce the risk of testicular tumors. The prognosis is good if the disease is detected and treated early. A balanced diet and responsible breeding practices can help minimize the risk. Research focuses on genetic and environmental influences as well as the development of new diagnostic methods to better understand and treat the disease.

Causes

Normal testicle descent in cats usually occurs within the first few months of life. During embryonic development, the testicles are initially located in the abdomen. They then migrate through the inguinal canal into the scrotum, where they should remain permanently. This process is controlled by hormonal signals, especially the hormone testosterone. The descent of the testicles is crucial for normal spermatogenesis at a lower temperature than body temperature.

Causes of cryptorchidism include genetic factors that can affect the correct development and descent of the testicles. Studies have shown that cryptorchidism is more common in some cat breeds, suggesting a hereditary component. Hormonal imbalances or mechanical obstructions in the inguinal canal can also prevent testicle descent.

Some researchers suspect that environmental influences during pregnancy, such as certain medications or environmental toxins, could also increase the risk of cryptorchidism. These factors could disrupt embryonic development and hormonal balance, leading to impaired testicle descent.

Symptoms

Cats with cryptorchidism often show no obvious symptoms, apart from the absence of one or both testicles in the scrotum. This can be detected during a routine physical examination. In bilateral cryptorchidism, where both testicles have not descended, the cat may be infertile because body temperature impairs sperm production.

Another potential symptom is an abnormal behavioral change. Cryptorchid cats may have an increased risk of hormonally related behavioral problems, such as aggression or restlessness. However, these behavioral changes are not specific to cryptorchidism and may have other causes.

In rare cases, testicular torsion can occur in an intra-abdominal testicle, which can lead to acute pain and other general symptoms such as vomiting, loss of appetite, and lethargy. An increased risk of testicular tumors occurring in undescended testicles has also been documented.

Diagnosis

Diagnosis of cryptorchidism is usually made by a thorough physical examination. The veterinarian will palpate the scrotum to determine if both testicles are present. If cryptorchidism is suspected, an ultrasound examination can be performed to determine the exact location of the undescended testicle.

In addition to imaging procedures, blood tests can be performed to determine hormone levels in order to assess testicular function. This can be especially helpful in bilateral cases to assess the cat’s fertility.

In doubtful cases, exploratory surgery may also be considered to determine the location of the testicle and take therapeutic measures at the same time. However, this is usually only necessary if the imaging procedures do not provide clear results.

Therapy

Treatment for cryptorchidism usually consists of surgical removal of the undescended testicle, a procedure known as cryptorchidectomy. This surgery is recommended to reduce the risk of testicular tumors and other health complications. In bilateral cases, castration is also performed.

The surgical procedure to remove the undescended testicle is usually performed through a small incision in the abdomen or groin area, depending on the location of the testicle. The surgery is relatively straightforward and usually has a good prognosis for recovery.

After surgery, postoperative care and monitoring are important to avoid infections or other complications. The veterinarian will provide instructions on how to care for the surgical wound and monitor the cat’s recovery.

Prognosis and follow-up care

The prognosis for cats with cryptorchidism is generally good, especially if the condition is diagnosed and treated early. Surgical removal of the undescended testicle eliminates the risk of testicular tumors and other complications. After surgery, most cats lead a normal, healthy life.

In bilateral cases, where both testicles have not descended, the cat remains infertile, which is not a major concern for most domestic cats that are not used for breeding. Removal of the testicles can also help reduce or eliminate hormonally related behavioral problems.

Long-term complications are rare as long as the surgery is performed correctly and postoperative care is adequate. Regular veterinary check-ups are still important to monitor the cat’s general health.

Prevention

To prevent cryptorchidism in cats, it is important to promote responsible breeding practices. Since cryptorchidism can have genetic causes, affected animals should not be used for breeding. Breeders should therefore ensure that breeding cats have no known history of cryptorchidism in their lineage in order to minimize the risk of passing this condition on to offspring.

Regular veterinary examinations are also important to detect possible signs of cryptorchidism early. In young male cats, testicle descent should be checked during routine examinations. Early detection can help avoid possible health complications.

A balanced diet and a healthy lifestyle also contribute to the cat’s general health and can indirectly help reduce the risk of developmental anomalies. It is important that cat owners are aware of the importance of genetic factors and responsible breeding.

Finally, cat owners should work closely with their veterinarian to understand potential risks and take appropriate preventive measures. Through a combination of genetic selection, regular health checks & a healthy lifestyle, the risk of cryptorchidism in cats can be reduced.

Outlook on current research

Current research on cryptorchidism in cats is investigating genetic, developmental, and environmental influences that can lead to this condition. Disrupted testicle descent is a developmental anomaly in which one or both testicles do not descend into the scrotum. This anomaly can be observed in both domestic and wild cats, and there is evidence that genetic factors play a role. Research teams around the world are working to identify specific genes associated with cryptorchidism in order to gain a better understanding of inheritance patterns.

Another important aspect of research is the study of hormonal influences on testicle descent. Scientists are analyzing the role of androgens and other hormones that play a crucial role during fetal development and shortly after birth. It is believed that an imbalance of these hormones could disrupt the normal descent of the testicles. Research in this area could lead to new approaches in the treatment and prevention of cryptorchidism.

In addition, the influence of environmental factors such as diet and exposure to certain chemicals on the development of cryptorchidism is being investigated. There is evidence that exposure to endocrine disruptors, which are found in some pesticides and plastics, may increase the risk of cryptorchidism. These findings could have important implications for breeding practices and the management of domestic cats.

A forward-looking part of the research focuses on the development of non-invasive diagnostic methods. Currently, cryptorchidism is mostly diagnosed by physical examination, but new technologies such as ultrasound and molecular markers could make it possible to identify the disease earlier and more precisely. These advances could improve treatment outcomes and help reduce the occurrence of complications such as testicular tumors.

Finally, the role of cryptorchidism in the reproductive biology of cats is also being investigated. Researchers are trying to understand how this disease affects the fertility and reproductive behavior of cats in order to develop more comprehensive breeding programs that minimize the risk of genetic anomalies. This research is crucial to improving the health and well-being of domestic cats in the long term.
