Yes you can find out if your child has TCS before they are born. I had what is called an amnioscentises when I was 10 weeks pregnant. Only it is important that doctors know where the problem lies in the person carrying TCS. No it is no passed down depending on sex orientation. Weather the adult is male or female there is a 50% chance that the child will be born with TCS. If you want more info on either of these please feel free to ask.
