Veterinary researchers at Urmia University in Iran have developed the technique – which leaves a stallion’s testicles in place but non functioning – and say that it has many benefits over traditional methods.
The new technique - Section-Ligation-Release – involves clamping, cutting, and sealing the spermatic cords of the testicles. Ordinarily the cords supply blood and nerves to the testicles. Deprived of oxygen and blood supply the testicles shrink within a couple of months and the horse’s testosterone levels fall in line with those of a traditionally castrated gelding.
The main benefits of the procedure are that the surgery – done through a 2 inch slit on each side of the scrotum, and completed in a matter of minutes – is far less invasive, resulting in less post operative discomfort for the horse, and requiring less after care.
The risks of post operative bleeding, swelling and infection are also greatly reduced.
The result, for some owners, may be more aesthetically pleasing, retaining the horse’s ‘natural’ look however, researchers noted, it would be important that records of the procedure be kept so that the horse’s status as s gelding could be accurately determined in the event of a sale, transfer or show.
The study will be published in a forthcoming edition of Reproduction In Domestic Animals.
