No point putting boys through surgery if there's no reason to. Unless you want to keep mixed sexes and get all the boys neutered for that reason. I had to neuter the 4 young boys I had here or I had to spay 28 females (at the time).
My intact rescue boy was 37 months when he died, my spayed rescue boy (same group) was 38 months...it doesn't mean that much.
