hkenny, that holistic stuff is interesting, except that all men later in life lose testosterone
levels anyway, whether or not they have had a vasectomy
, and that can certainly make them feel tired and sluggish. (This is where the classic archetype of the "grumpy old man" comes from.) My dad had a vasectomy after his fifth child, and he never has felt tired and sluggish, and he is 79. I think holistic doctors are fine, but their science is sometimes less than rigorous.
