FIELD: veterinary medicine. SUBSTANCE: method involves preparing an animal under general and local anesthesia. All layers (skin, subcutaneous fat, fascia, vaginal tunic of testis) are dissected with scalpel. The testis is taken out, proper ligament is transected and the testis is pulled to the maximum degree outward. Then sperm ejaculation duct wall and spermatic cord are laminated. The sperm ejaculation duct is separated from the testis with a part of epididymis head. Separation being accomplished, the sperm ejaculation duct and spermatic cord are tied with several surgical knots. EFFECT: reduced risk of post-operation complications; small quantities of suture material consumed.
