Will having sex twice lead to fraternal twins?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

Fraternal twins are when two eggs have been released and both get fertilized by two different sperms. Does this mean the woman had sex twice to fertilize the second egg or one sperm fertilized both of them?

Hi,

Welcome to icliniq.com.

Actually, twins are babies produced by single same pregnancy can be monozygotic (identical) or dizygotic (fraternal). Monozygotic develop from one zygote which splits in an early stage of development and form two embryos. Dizygotic (fraternal) twins mean each twin develop at the same time from a separate egg and each egg is fertilized by its own sperm at the same time. It means woman had sex once only and at time fertilization two eggs fertilized by two sperms. In a few milliliters of semen, millions of sperms are there. So two sperms used to fertilized two eggs.
