I noticed after 13 weeks in Bicalutamide, that I hadn't been routing T-shirts to the wash following the usual sniff test for some weeks. Basically, they didn't smell 'worn' at all. I stopped using deodorant - I didn't need it anymore.
Loss of body odor must have happened some weeks before I noticed, but I don't know precisely when.
Like Chris said, I still sweat loads (I cycle), but it generates no odor in my clothes or on me.
Now, if you are noticing a *new* smell, it might be something that was always there but masked by BO, and might not even be generated by your body, but maybe by soap or washing detergents or other perfumed products.
Of course, there are some medical conditions which can generate other odors such as Ketoacidosis caused by alcoholism, lack of carbohydrates in diet, or diabetes.
