TL;DR: Cryptorchidism is a common condition where one or both testicles fail to descend; while not an immediate emergency, it requires a scheduled veterinary visit for neutering to prevent future health risks like cancer.
What is cryptorchidism and how does it affect my puppy?
Cryptorchidism occurs when one or both testicles fail to descend into the scrotum. In a typical puppy, the testicles develop near the kidneys and gradually move down into the scrotum as they grow. If this process is interrupted, the testicle may remain in the abdomen or the inguinal canal (the groin area). This condition is fairly common in puppies and is often discovered during their initial series of wellness exams.
Is a missing testicle in my puppy considered a medical emergency?
- The urgency level for a missing testicle is low, as it is not an immediate life-threatening emergency and your puppy is likely not in pain.
- This condition needs to be addressed during a scheduled veterinary appointment rather than an emergency visit.
- Retained testicles are significantly more prone to developing cancerous tumors and complications like testicular torsion later in life.
- Your veterinarian will likely recommend neutering your dog to remove both the descended and the undescended testicle.
How does providing a photo of my puppy's groin area help the triage team?
- A clear photo allows professionals to check for localized swelling, redness, or skin irritation.
- Visuals help determine if the testicle is positioned just under the skin or if there are other visible abnormalities.
- This information helps the clinic determine the appropriate timeline for your appointment and helps the doctor prepare for the physical examination.
Clinical Context (Merck Veterinary Manual)
Cryptorchidism, the failure of one or both testicles to descend into the scrotum, is a common condition in dogs and is typically diagnosed if the testicles are not present in the scrotum by puberty, although normal descent usually occurs by 6-16 weeks of age, with some documented cases as late as 10 months. Unilateral cryptorchidism is more common than bilateral, and while it usually allows the male to remain fertile, bilateral cryptorchidism results in sterility. The undescended testicle may be located anywhere from just caudal to the kidney to within the inguinal canal and can be identified via palpation or ultrasonography. Due to the suspected inherited nature of cryptorchidism and the increased risk of neoplasia and torsion in retained testicles, bilateral orchiectomy is recommended, and affected animals should not be bred; attempts to induce testicular descent with medical therapy or orchiopexy are considered unethical.
