This is what the article said:
"One of my pet peeves is that people take ultrasound for granted when it comes to gender determination. Not only can ultrasound be inaccurate, but there is also what I call the "Absence of Penis = Girl" theory.
This theory states that if the ultrasound technician fails to find a penis the baby is automagically a girl. Here are some ultrasound of different "parts" for your viewing. You will see that clearly a girl is more than the absence of a penis."
WELL NO SHIT IT'S A GIRL IF IT HAS NO PENIS!
