Twins can occur either when two separate eggs become fertilized in the womb or when a single fertilized egg splits into two embryos. Having twins is more common now than it was in the past. According to the Centers for Disease Control and Prevention (CDC), twin births have nearly doubled over the last 40 years.
Can twins have different dads?
It is possible for twins to have different fathers in a phenomenon called heteropaternal superfecundation, which occurs when two of a woman’s eggs are fertilized by sperm from two different men. Ordinarily, a woman becomes pregnant because one of her eggs has been fertilized by sperm.
