The ultrasound technician needs to look at certain additional views of the developing fetus in order to determine this angle. But remember, this is usually not part of the routine ultrasound at this gestation age. The way the genital tubercle forms into the penis of a boy fetus is different from how it forms into the clitoris of a girl fetus.īy looking at the angle of the genital tubercle, it is possible to distinguish between a boy and a girl fetus. The part of the fetus that is developing into either girl parts or boy parts is called the genital tubercle. If the thickness of the nuchal translucency is more than 3.5 mm, it is associated with an increased risk of Down syndrome.Īt this gestational age, you can't distinguish between the genders on ultrasound. Both a boy and a girl fetus have this fluid-filled space. The ultrasound technician will measure the fold on the back of the fetal neck.

An ultrasound at this gestational age will help confirm your due date, and it is part of the early risk assessment testing (ERA) for a chromosomal abnormality, such as Down syndrome. Having an ultrasound between 11 to 14 weeks is common.
