Retained testicle is also known as “crypt orchid”. The testicles normally descend from their embryonic location near the kidneys through the abdominal cavity out the inguinal canal to the scrotal sac within weeks of birth. If both testicles are not descended by the age of 5-7months the neuter procedure is postponed for a few months to allow the testicles to “drop.” If by one year of age, the retained testicle is still in the abnormal environment of the abdomen, abdominal surgery is necessary to remove the retained, disease prone testicle. Retained testicles are at higher risk of testicular cancer. The condition is inherited and retained testicle males should not be bred, as many offspring will suffer the same dangerous condition.
