A Brazilian woman claimed to have had intercourse with two guys on the same day and then gave birth to twins with different fathers.
The Brazilian 19-year-old, who requested anonymity and is from Minerios in Goias, stated that she underwent a paternity test to determine the identity of the father.
Having questions about the father’s identity after eight months, she made the decision to get the test done.
The 19-year-old said that she obtained DNA from the man she believed to be the twins’ father but that after two tests, only one of the twins’ findings was found to be positive.
After the second test, she realised she had slept with a different man that day and claimed that when he did the test, it showed that he was the father of the second twin.
Scientifically, the occurrence is known as heteroparental superfecundation.
According to her doctor, Tulio Jorge Franco, when two eggs from the same mother are fertilised by separate men, it is feasible for this to occur. Although the babies develop in various placentas, they share the mother’s genetic makeup.
He emphasised the rarity of the case, calling it a “one in a million” circumstance, and said he didn’t expect to see another one like it in his lifetime.
