Ejaculatory failure associated with aortic-iliac thrombosis in two stallions.

The study discusses the case of two breeding stallions found to have aortic-iliac thrombosis leading to ejaculatory dysfunction. By managing sexual arousal, reducing leg pain, and introducing gradual, daily exercise, the researchers were able to improve the breeding performance of the stallions.

Objectives of the Research

• The study aimed to understand the underlying causes of specific ejaculatory dysfunction in two stallions.
• The researchers sought to determine a practical solution or treatment for the issue, focusing on increasing sexual arousal, reducing hind limb pain during mating, and implementing a regular exercise regimen.
• Another goal was to emphasize the need to include aortic-iliac disease in the differential diagnoses when dealing with specific ejaculatory dysfunction.

Detailed Findings

• Both stallions exhibited strong libido, normal mounting behavior, and vigorous initial thrusting. However, over time, their thrusts weakened, and dismounting became awkward.
• Tests indicated the presence of aortic-iliac thrombosis in both stallions. This vascular disorder was responsible for occluding 60 to 70% of the aortic lumen.

Treatment Implemented

• The researchers manipulated the breeding environment to enhance sexual arousal before mounting to overcome the physical limitation caused by the vascular disorder.
• Treatment strategies also included measures to reduce the hind limb pain experienced by the stallions during mating.
• A regular exercise regimen was introduced, with intensity intended to gradually increase over time.

Results of the Treatment

• This combination of treatments reportedly allowed the stallions to continue breeding, indicating an improvement in their sexual performance.
• Furthermore, the research showed improved breeding performance in subsequent breeding seasons due to the implemented exercise program.
• The findings suggest that sexual dysfunction in stallions due to thrombotic disorders can be addressed using the given approach.
