Have you ever heard the term Heteropaternal Superfecundation? No, it’s not a funny saying from Mary Poppins. It’s the technical term used when twins have different biological fathers. This is a rare occurrence that can only be verified with a Paternity Test. Some believe this is a one in a million chance.
MSN reports on one family from Texas that experienced this first-hand. A woman gave birth to fraternal twins with different biological fathers. This was verified after conducting DNA testing with paternity results. A Paternity test was performed after suspicions grew as a result of the twins not looking anything alike. Although many twins look nothing alike, one father decided to verify paternity. Paternity results verified the twins did indeed have different biological fathers. How does this happen? How is it possible? MSN explains how this occurs.
Every month a woman’s ovary releases one egg, and in rare cases the ovary releases two. Sperm can live up to 5 days in the reproductive tract of a female. The egg is viable for 12-48 hours before it starts to disintegrate. This gives a 4-5 day period in which two different men can fertilize one egg each. Paternity results (DNA Testing) is the only way to know for sure if this has happened, and indeed it did in this case.
