If your family has a history of twins, you might be curious if that could influence your own chances of having twins. The short answer is: it can, but it’s not as straightforward as you might think. Let’s dive into the details of how heredity plays a role in conceiving twins.
Do Twins Run in Families?
Yes, certain types of twins can indeed be hereditary. Specifically, fraternal twins—those that develop from two separate eggs fertilized at the same time—are more likely to occur if there’s a family history on the mother’s side. Studies suggest that if there are fraternal twins in your immediate family, your chances of having your own fraternal twins might double. This increase in likelihood is thought to be linked to a gene that may cause some women to experience “hyperovulation,” allowing them to release multiple eggs during ovulation.
However, the connection isn’t crystal clear, as not many specific genes have been conclusively tied to hyperovulation. It’s possible that genetics play a broader role in increasing the chances of having fraternal twins.
