Hmm, don't know,

I couldn't see the pic very well.

If you go to my site you can see a between the legs shot of a little fella at 19 weeks.

He took a whiz just as the sonographer was getting into position so we didn't miss him.
If you look at it, at the bottom is a shin and above that you see a little nub like thing with like a thin line (stream of pee) coming from it.

After that she was so certain it was a boy we didn;t even get the standard disclaimers.
