Horses were sedated using xylazine hydrochloride (0.5 to 1 mg\/kg) and butorphanol tartrate (0.02 mg\/kg) or detomidine hydrochloride (0.02 to 0.03 mg\/kg) and restrained in standing stocks. Three portal sites in the paralumbar fossae were locally desensitized using 2% mepivacaine. After trocar and laparoscope insertion, the ipsilateral testicle, mesorchium, and ductus deferens were identified. The cranial mesorchium was coagulated with either monopolar (one horse) or bipolar (nine horses) electrosurgical forceps, and then the mesorchium, ductus deferens, and ligament of the tail of the epididymis were transected from cranial to caudal using laparoscopic scissors. Once the testis was freed, the transected mesorchium was inspected for hemorrhage and the testis was removed by connecting the two instrument portals (eight horses). In two horses, the testis was placed within a laparoscopic retrieval bag and then removed without enlarging the portal incision. If the testes were retained bilaterally, the retained contralateral testis was removed similarly through the opposite paralumbar fossa. If the contralateral testis was descended, it was removed by a standard, standing castration technique.<\/jats:p><jats:p><jats:bold>Results\u2014<\/jats:bold>Vessels of the mesorchium were adequately coagulated using bipolar and monopolar electrosurgical forceps.
