At what point does a fetus become a boy or girl?
Your baby’s gender is determined at the moment of conception – when the sperm contributed a Y chromosome, which creates a boy, or an X chromosome, which creates a girl. Boys’ and girls’ genitals develop along the same path with no outward sign of gender until about nine weeks.
Do fetuses start as female?
