Cryptorchidism is a medium-severity urinary condition that can affect dogs of all ages and breeds. Cryptorchidism is failure of one or both testicles to descend into the scrotum by 6-8 weeks of age. Retained testicles are at significantly higher risk of torsion and Sertoli cell tumour development and must be surgically removed. It is documented across 6 breeds, though prevalence and severity can differ significantly between them. It typically becomes apparent at Birth — detected at 6-8 week check. Early signs to watch for include absent or asymmetric scrotum, retained testicle palpable in inguinal region or abdomen, sudden abdominal pain if torsion, and feminisation syndrome if sertoli cell tumour develops. When treatment is required, costs are estimated at £500-£1,500 depending on severity, location, and the specific intervention needed. Cryptorchidism has a hereditary component, so health-screening certificates from the breeder are strongly recommended for predisposed breeds. This page covers symptoms, treatment options, and preventive steps — along with breed-specific information where available.

Signs & Symptoms

The following symptoms are commonly associated with Cryptorchidism in dogs. If your dog displays several of these signs, consult your vet promptly — early diagnosis typically leads to better outcomes.

• Absent or asymmetric scrotum
• Retained testicle palpable in inguinal region or abdomen
• Sudden abdominal pain if torsion
• Feminisation syndrome if Sertoli cell tumour develops

Treatment Overview

Surgical orchidectomy of the retained testicle (and the descended one) is essential. Retained testicles cannot be medically induced to descend and carry tumour risk.

Typical onset: Birth — detected at 6-8 week check

Prevention & Screening

While not all cases of Cryptorchidism can be prevented, the following steps reduce risk or enable earlier intervention:

• Do not breed from cryptorchid males or their sires
• Genetic component — avoid breeding close relatives of affected dogs
