One of my pet peeves is that people take ultrasound for granted when it comes to gender or sex determination. Not only can ultrasound be wrong, 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 automatically a girl. You will see that clearly a girl is more than the absence of a penis.
