Plain-English summary
Two mature stallions that were used for breeding were having trouble with ejaculation, but they still showed interest in mating and were able to mount normally at first. However, as they continued, their thrusting became weak and they had difficulty dismounting. The problem was found to be caused by a blockage in a major blood vessel, which was affecting their ability to breed effectively. Treatment focused on increasing their arousal before mating and reducing discomfort during the process, along with a gradual exercise program that helped improve their performance in future breeding seasons. Overall, the treatment worked, allowing the stallions to continue breeding successfully.
Abstract
Two mature breeding stallions were evaluated because of specific ejaculatory dysfunction, and each was found to have aortic-iliac thrombosis occluding 60 to 70% of the aortic lumen. In each case, the stallion had strong libido, normal mounting, and vigorous initial thrusting. With continued exertion, thrusting became weak and dismount was awkward. Treatment aimed at maximizing sexual arousal before mounting and reducing hind limb pain and exertion during breeding allowed these stallions to continue breeding. A program of gradually increasing daily exercise also was associated with improved breeding performance during subsequent breeding seasons. In cases of specific ejaculatory dysfunction, aortic-iliac disease should be included among the differential diagnoses.
