For women, there are things called "Sperms". There is an <em>egg </em>in the women. Think of colors. Say an orange sperm is a boy and a yellow sperm is a girl. If the yellow sperm reaches the egg first, the baby will be a girl. If the orange sperm reaches the egg first, the baby will be a boy. Think of it as a Sperm-race.
If two yellows, two oranges, or one of each comes to the sperm at the same time, you'll have twins.
Same with triples, quadruplets, etc, even though this is very rare.
