How do girls get pregnant twins?​

There are many myths about how to improve the odds of having twins. Although there are no proven ways to increase the likelihood of conceiving twins, there are certain factors that can make this type of pregnancy more likely.

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)Trusted Source, twin births have nearly doubled over the last 40 years.
