Abstract

Canine overpopulation is a worldwide problemespecially in rural areafor this reason many researches have been performed to choose the most effective and less invasive technique for sterilization of male dogs with minimal complications. This study aimed to evaluate the possible outcomes and complications following bilateral electrocoagulation of testicular blood supply, as a method of sterilization of male dogs.Sixstray male dogs were used in this work. Electrocoagulation of the testicular blood supply was induced through a prescrotal 1-2 cm incision length followed by separation of spermatic cord and exposure of testicular blood vessels. The outcomes were measured depending on clinical signs, Histopathological evaluation, ultrasonographical evaluation and testosterone level estimation. Overall results were satisfactory. Electrocoagulation of testicles was accompanied by a very short prescrotal incision with less operation time. Some difficulty was relevant during dissection and separation of testicular blood supply with mild to moderate bleeding. Some inflammatory reaction followed by marked testicular atrophy was observed. Severe coagulative necrosis of seminephrous tubules and remnants only of mature spermatozoa were found. Ultrasonographical findings revealed marked decrease in testicular dimensions with uniform hypoechoic appearance of testicular matrix. It could be concluded that bilateral Electrocoagulation was proved to be safe and effective method for dog sterilization without any complication.
