How Can You Tell If You Are Having a Boy?

The most accurate way to determine whether a pregnant woman is having a boy is through medical procedures such as amniocentesis, chorionic villus sampling and fetal DNA testing, explains WebMD. Ultrasound is also an option, but it is not as accurate.

Although certain medical procedures can identify a fetus' gender, the tests are meant to uncover chromosomal disorders and other genetic factors. Because some of these tests carry a small risk of miscarriage, these methods are only conducted if the mother falls into a specific risk category, states BabyCenter.

An ultrasound at 20 weeks may uncover the gender of the fetus, but occasionally the technician cannot get a good view of the genitals, and the image may be misread. Practitioners use ultrasound to gauge fetal growth, position, health and amniotic fluid levels. Uncovering the fetal gender is simply a bonus, and the procedure is not recommended for only determining the sex of the fetus, points out WebMD.

If a woman does not need or desire prenatal testing, she may consider some harmless myths for determining a fetus' gender, notes Parenting. For example, if the fetal heart rate is greater than 140 beats per minute, it's a girl, if less, it's a boy, according to the saying. Mothers who crave salty or sour foods are thought to be more likely to have a boy. For those with a sweet tooth or extreme morning sickness, a girl is most likely the cause. Even though these symptoms possess a certain degree of accuracy for determining fetal gender, expectant parents should not pick a blue or pink nursery color based on these assumptions.
