I don't agree with this solely on functionality. Angelina Jolie specifically had the procedure done to save the nipple, which is really the only functional use for breasts, in terms of breast feeding, and even then is only for when you have newborns. My testicles have quite a bit more purpose, in terms of reproducing. Not having any children yet, I would be much more hesitant to simply hack them off, at least not without making a hefty donation first to at least try and have kids someday. Again, this is just functionally, I do get there is an emotional aspect, especially for someone like an actress who is known for her looks.
