If mice studies were analogous to humans, we would have cured numerous things by now. I'm all for taking correlation as worthy of follow up research, but I aint chopping off my balls based on it.

They note that castration is known to benefit longevity in a wide range of mammalian species. So I think there is a good chance there is something real here. Anyway the real prize is of course the castration mimetic drugs they hint at, that would give the benefits without having to actually remove the balls.

There are better reasons to get your balls chopped off
