The first pic doesn't look like a penis at all, I would say it is the umbilical cord. Jackson and Leo's bits were very clear, and the penis and testes look exactly like a little turtle, a sort of stubby mound with the penis out the middle (ie. the turtle head poking out of the shell)

The second pic could possible resemble more of the shape I am talking about but it really isn't clear enough, and as Fletch said the penis and the clitoris look pretty much alike at this stage - I would be waiting for more clear evidence @ the 20 week scan before decorating the nursery!
