Complications from a testicular prosthesis in a stallion.

This research focuses on the case of a young male horse that experienced complications arising from a testicular prosthesis. The study suggests that the prosthesis might have prevented the normal descent of the testis, leading to further complications.

Introduction

• The research revolves around a unique case of a three-year-old Quarter Horse stallion which had earlier been fitted with a testicular prosthesis due to a retained left testis that could not be repositioned successfully.
• The prosthesis, however, had to be removed after ten months due to a persisting draining fistula, located on the scrotum and initially discovered five months after the placement of the prosthesis.

Procedures and Findings

• In the course of surgery, it was observed that the left testis was located in a fibrous mass that was enclosing the prosthesis. This unexpected discovery indicated that the testis had descended post-prosthesis placement.
• The fibrous tissue, affected by the infection from the prosthesis, was entangled with the descending testis. This condition necessitated the removal of the problematic testis to alleviate the horse’s ailment.

Implications and Conclusion

• Based on the findings, the researchers suggested that if the artificial testicle had not been installed, the natural testicle probably would have descended normally, resulting in a healthy and standard stallion physiology.
• This study, therefore, implies that the use of a testicular prosthesis carries some risk and should be carefully considered and monitored over time to answer better how to treat testicular issues in horses.
