Retrospective study of 350 cases of equine cryptorchidism.

Equine cryptorchidism was examined by a review of the literature and a retrospective study of 350 horses over a 14-year period. The incidence of left vs right testis retention was nearly equal. On the left side, 75.2% of the retained testes were retained abdominally and 24.8% inguinally; on the right side, 41.8% of the retained testes were retained abdominally and 58.2% inguinally. Preoperative diagnosis by rectal palpation of the vaginal rings was considered a valuable technique, with 87.9% accuracy in 190 horses. Invasive and nonivasive surgical techniques for abdominal cryptorchidectomy and associated complications were compared. The results supported the technique of traction on gonadal structures outside the abdominal cavity (noninvasive) as superior to techniques requiring intraabdominal manipulation (invasive).
