Sex Determination and Differentiation 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 Müllerian ducts. The Wolffian ducts are embryonic structures that can form the male internal reproductive system.

When and how can I find out my baby's sex? Other people find out their baby's sex from a genetic test like CVS or amniocentesis. These tests are usually used to determine whether a baby has a genetic disorder or a chromosomal abnormality like Down syndrome but may carry a slight risk of miscarriage. CVS is typically done between 10 and 13 weeks and amniocentesis between 16 and 20 weeks.
