Finding Out the Sex of Your Baby

By Robin Elise Weiss, LCCE, About.com Guide

When doing ultrasound, we're working really hard to be able to tell a parent the sex of their baby earlier and earlier. The problem is that the earlier you are told the more likely the ultrasound technician is to be wrong. Ultrasound before 18 weeks runs this risk because the genitals of boys and girls are easily mistaken, namely because the clitoris is roughly the size of the penis at this stage.

It's hard to tell at 15 weeks but the technician's best guess is boy.
