Testicular dystopia, Testicular removal, Surgery


Cryptorchidism is a reproductive alteration in males, characterized by the absence of displacement of one or both testicles from the abdominal cavity to the scrotum. The diagnosis must be made through visual inspection and careful palpation of the scrotum. A male cat, six months old, SRD, weighing 2.7 kg, was seen at a Veterinary Clinic in Arapiraca/AL, weighing 2.7 kg, for a routine medical consultation. Upon palpation, when walking the physical examination, it was observed that the patient did not have testicles in the scrotum. The treatment of choice for cryptorchidism in this case was bilateral castration, mainly due to the fact that the pathology is hereditary. The occurrence of bilateral cryptorchidism is not common in cats, being of multifactorial etiology little described in this species due to the absence of clinical signs, compromising the animal's fertility, passing unnoticed by the owner and being little discussed in the literature.
