The babies sex is determined by the sperm. The egg has XX chromosome and each sperm cell is either a XX or XY chromosome. So which ever sperm cell reaches the egg and implants determines the sex. If the sperm was an XX chromosome the baby would be a girl, if the sperm was XY chromosome the baby will be a boy.
