I also have seen geldings cover a mare years after being gelded, but could never produce anything.
I agree, geld him and he will be much happier. I know several Mini owners here who have gelded horses in their late teens and had no problems. A couple of years ago a friend gelded one who was almost 8, and had WAY too much testosterone for his own good. He never was sore nor did he take it any harder than the weanlings and yearlings that were all gelded at the same time. It didnt set him back at all and he, and everyone around him
are much happier!!
