When can I find out my baby's gender?

Your mid-pregnancy ultrasound (usually done between 16 and 20 weeks) involves a detailed anatomical analysis of your baby and is usually when you will be able to find out if you're carrying a boy or a girl–if you want to, that is.

"In our experience, about 80 to 85 percent of parents want to know the sex of their baby when they come for an ultrasound," say Dr. Benson. "If we get a good look between the legs, as we can in most pregnancies beyond 15 to 16 weeks, ultrasound is close to 100 percent accurate at sex determination."

However, the ability to determine the baby's sex depends on a number of factors, including the position of the baby, whether his/her legs are open and whether his/her hands are covering the "private parts." The mother's weight is another factor. "Ultrasound images are far less clear in heavy women than they are in thinner women, so we may not be able to figure out the baby's sex in a heavy woman until 18 to 20 weeks."
