In an orchidectomy, the testicles are removed by a surgical procedure that may vary depending on their location. If the testicles are located in their normal position within the scrotum, a small incision is made in the skin over each testicle. The testis is pulled out of the incision and the spermatic cord is tied off to prevent bleeding. The spermatic cord is then cut, examined for bleeding, and allowed to return to its normal position inside the incision. Because the incisions are small, they do not need to be sutured closed.
If the testicles are not in their normal position, the veterinarian will try to locate them by palpation. The testicle may be anywhere from inside the abdomen to along the inguinal tract. If the testicle is located under the skin along the ventral abdomen, an incision is made just over it. The remainder of the surgery is performed as above. If the testicle is located in the abdomen, an incision is made in the ventral abdomen, while care is taken to avoid the area blood vessels. In this case, the testis is located by following the spermatic blood vessels and ducts to their testicular connection within the abdomen. Once found, these structures are tied off and the testis is removed.
