How to Know the Sex of the Baby With a Sonogram

14 Weeks

1). Look at the sonogram picture and find the lower part of the fetus' spine.
2). Look at the sonogram picture and find the genital tubercle. This will be at the end opposite the head and will protrude slightly.
3). Determine the genital tubercle's angle. If the angle is greater than 30 degrees from the lower part of the spine, the fetus is a boy. If the angle is less than 30 degrees, or even parallel with the spine, it is a girl.

1). Look at the sonogram picture and find the legs. At this stage, the fetus will most likely be slightly folded up inside the uterus.
2). Look at the sonogram picture and find the genitals between the legs.
3). Determine the number of lines on the genitals. If there are fewer than three lines, it is most likely a boy. If the fetus has three distinct lines, it is a girl.
