Is it possible for your ovary or your fallopian tub to grow back after being removed by surgery. If so how long would it take. How can I tell if my tub is there or not. I have had two U/S and a cat scan. They are only telling me that I have a overy that was supposed to have been removed. They also told me that they could not see if I had my tub unles there was a problem with it. Is this true??

No, neither your ovaries nor your tubes "grow back" once they are removed.
