Body Parts = Identity

I was watching an episode of "Scrubs" today, one that i had seen but nothing else was on. One of the doctors, Turk, admits to his best friend that he had surgery to remove a testicle. He also reveals that he feels like less of a man now that he only has "one ball". he also states that he was over compensating for losing his testical by being more confrontational and wresteling with J.D.

I found this interesting. Are we so attached to what is seen as female and male parts that without one we feel less of a presona. The same thing happend in the lifetime movie "Why I wore Red Lipsitck to my Mastectomy". the main character gets breast cancer and has to contimplate getting her breast removed. She goes though all the things that Turk went though. So while it isnt a one gender thing, why are we so attached to the idea of these body parts. while they help to define us, they are not all that we are and all that we represent.
