Who's your Daddy?

Thomas Beatie made international headline news last year as he became known as 'The Pregnant Man' Well he gave birth to a girl, Susan back in June.

Now he's pregnant again...

Tonight ,on 20/20 Barbara Walters is interviewing the expectant couple about, life, love, pregnancy and just how do they have sex? (You know you want to know! I know I do.)

This just raises so many questions... What makes a man a man? and to that end, a woman a woman? How can you only go part way through a sex change (ie: hormone treatments, breast removal, but leave the reproductive organs, and lets face it, not have a penis -construction, add on, strap on, whatever - and be legally defined as a Man? What gets listed on the birth certificate as far as mother and father?

But most importantly... does it really matter?

I have to say it's a rather complex and confusing story / concept, and even though it's Baba Wawa I will watch the show tonight because I am intrigued!
