I had TULSA PRO done last Nov. I had three cores showing cancer. The MRI the Dr. showed me looked like the whole gland was ablated, I'll ask about that in June when I go back for follow up. My erection may be better than before the procedure. It will take a little while to gain confidence that it will work. Viagra works really well for me. One pill will last a couple of days or more. I also have a dry orgasm. My Dr. told me that is normal after the procedure.
