Question: how to determine baby gender on ultrasound?
Answer: When doing an ultrasound to determine the sex of your baby, an ultrasound technician will actually look for girl genitalia—labia and clitoris. 2﻿ When these are seen, it is often referred to as the "Hamburger Sign." The clitoris situated between the labial lips looks like a hamburger between two buns, or three lines.
