Causes of Identical and Fraternal Twins The Causes of Dizygotic (Fraternal) Twins. Dizygotic or fraternal twins form in the same way that all humans do, by the union of sperm and egg. The explanation for dizygotic twinning lies in the cause of hyperovulation, or the release of more than one egg in a cycle of ovulation. There are numerous reasons for hyperovulation, and any one or combination of factors can be attributed as the cause for fraternal twins. Hormones control the process of ovulation.
