Sex Organs Are Visible. Although your baby's gender is determined immediately upon fertilization, you will not be able to know the sex until about the 16th to 18th week of pregnancy. At around the sixth week your baby will develop a small bud called the genital tuber at the site of the genitals.
This process starts before the developing child is even old enough to be considered a fetus, and is instead still an embryo. A developing human is not considered a fetus until the 9th week of development in the uterus, whereas sex differentiation begins during the 6th week of pregnancy. By the sixth week of development, all embryos have both Wolffian ducts and MÃ¼llerian ducts. The Wolffian ducts are embryonic structures that can form the male internal reproductive system.
