Yes, the man decides the gender of a baby. During conception, the sperm from the male can carry either an X or a Y chromosome. If the sperm carries an X chromosome and fertilizes the female's egg (which always carries an X chromosome), the baby will be female (XX). If the sperm carries a Y chromosome, the baby will be male (XY).
