Abstract: A 4-year-old thoroughbred mare was referred to the Jeju National University Equine Hospital as it exhibited stallion-like behavior and was unmanageable during training. A transrectal ultrasound revealed an enlarged left ovary. We decided on a standing laparoscopic ovariectomy through the left flank. Three portals were positioned to permit triangulation for optimal visualization with minimal incisions. The enlarged ovary was resected successfully. Histological examination confirmed the presence of a fibroma. The mare recovered without complications and returned to racing within 3 months post-surgery. The successful outcome seen in this mare indicates that laparoscopic surgery has multiple advantages, including faster recovery times and minimal scarring. This approach is recommended for mares presenting with ovarian fibromas, particularly those intended for a future career in athletics.
