Not noticed any such change when I was on bicalutamide, or Zoladex now. Never done prostap myself.
Another thought - diet or diabetes?
Ketoacidosis can be quite smelly. It's when your body is deriving most of its energy from fats, rather than sugars.
It can happen on a carb-free diet (which is harmless apart from the body smell as far as I know), and it can also happen with diabetes where you can't absorb and use the sugar in your blood, so your body burns fats instead (and sugars remain in blood unused and at elevated levels).
Also happens with alcoholics.
Quite often, people suffering this don't seem to be able to smell it themselves.
