All of the medical sites i've looked at say there is *some* evidence of a
difference, such as a tendency for unusual tallness and thinness,
antisocial and behavioral problems, and severe acne during adolescence.
Intelligence is sometimes lower as well.

*however* the above are not common and don't always occur with xyy males.
Some look and behave very much like an XY male.
