Seminal vesiculitis and blocked ampullae occurring simultaneously in a stallion

Year: 2025

Type: article

Abstract: A Gypsy Vanner stallion presented with a history of subfertility and abnormal dense, grey ejaculate. Reproductive examination including ultrasound, cytology, and bacteriology confirmed the diagnosis of seminal vesiculitis. After evaluation of several ejaculates, bilateral blocked ampullae were confirmed by azoospermia and a low level of alkaline phosphatase (30 IU/L) in the filtered fraction. Continuous semen collections, along with oral antibiotics treatment, were performed at the owner's facility for five weeks. After readmission, a successful collection was obtained with a high concentration and low motility. Seminal vesiculitis persisted, local antibiotic treatment of the seminal vesicles (SV) was initiated using video endoscopy, to improve response to treatment. After completing a total of 7 weeks of oral and local SV treatment, the seminal vesiculitis resolved. Despite persistent low semen quality, the stallion has successfully impregnated 2 out of 5 mares (40 %), with confirmed pregnancies and heartbeats.
