With the ram lamb in dorsal recumbency, the spermatic cord was pulled laterally and a 26 gauge needle was inserted in a caudal to cranial direction through the scrotal skin, adjacent to the medial aspect of the spermatic cord. Next # 1 chromic catgut was threaded through the needle. The hypodermic needle was then reinserted through the same holes, caudal to cranial, but this time lateral to the spermatic cord, and the suture material again threaded through the needle which was then withdrawn. The spermatic cord was ligated by tying the ends of the suture.
