Might sound like a funny question but " Does the size of a Stallions testicles determine his fertility "
I disagree. I have been told, several times, by both canine and equine vets that the bigger the testicles, the more sperm the stallion produces. So while size may not make a huge difference, it does affect the number of sperm a horse produces. I believe this can make a significant difference in how fertile a horse is for AI.
As noted in the article, there are many variables that go into a stallion's fertility. I had one stud dog that had chronic sporadic motility and low sperm count problems. His definitive diagnosis (on necropsy) was that he had chronic inflammation of the testes, probably from a low grade infection at some point. As long as there is nothing else going on, a stallion with larger testicles will produce more sperm than a horse with smaller testicles.Nope. You can have a huge set that produce very little or no sperm and vice versa. The Grand Prix jumper Cumano has a humungous pair and is well known for having poor quality/low quantity sperm.
No kidding! Last thing I need is Nort & Pooka comparing boy berries!I don't want to see any additional "one-up-manship" between Destiny & DunIT![]()
