Sheath Edema In Male Horses

The sheath is at the farthest point from the heart and damage to the blood flow in castrated males can sometimes prevent the normal flow of blood leading to swelling (edema) of the sheath.
These photos have captions to express any thoughts I have on the picture. The idea here is for YOU to get ideas, so grab a cup of coffee, darken the room, grab a pen and paper to write notes, and sit back and enjoy. I have more shots and I’ll add them later as I have time.

  1. I have wondered and done research with no answer to this question. I am a certified equine massage therapist and I also own a professional sheath cleaning business… So I deal with this A LOT! I was wondering if it was something to do with the lymphatic system that the sheaths would get swollen… I see it on top show horses to back yard horses.. I also wondered if it was a precursor to Cushing’s disease?

    So any thoughts on why some have only one side edema? Thanks so much for the topic!
