It’s that time of year. The yearling year of a horse is the best time to perform a castration. Castration in a horse is a very non-invasive and safe procedure that can be done on the farm.
However, if both testicles are not descended normally into the scrotum, the horse is considered a cryptorchid.
Preforming a castration on a cryptorchid can be a bit more challenging and should be done at a hospital.
Generally one sided (unilateral) cryptorchids are fertile, while having both testicles retained (bilateral) cryptorchids are generally sterile. Prevalence of left and right testicular retention is nearly the same for both the left and right testicle.
The retained testicle may be located anywhere within the abdomen or the inguinal canal. The left testicle tends to be in the abdomen, whereas the right testicle tends to be in the inguinal canal. To read more pick up a copy of the August 2016 issue.
