Deemed as a one-in-a-million conception, a 19-year-old Brazilian woman gave birth to twins nine months after having sex with two men on the same day.
As the first birthday of the twins approached the mother began having doubts over who the father of the twins was.
Putting an end to her curiosity, she decided to take a paternity test to confirm her suspicions, local news outlet news outlet Globo reported.
The woman originally suspected only one of the two men to be the father of the twins, so she collected his DNA — but it only turned up positive for one child.
“I remembered that I had had sex with another man and called him to take the test, which was positive,” the new mom, who asked not to be identified, told the outlet. “I was surprised by the results. I didn’t know this could happen. They are very similar.”
Dr. Tulio Jorge Franco, the woman’s attending physician, told local news outlet Globo, “It is possible to happen when two eggs from the same mother are fertilized by different men. The babies share the mother’s genetic material, but they grow in different placentas.”
Dr. Franco admitted he never thought he would see a situation like this in his lifetime as it’s “one in a million” — and claims there are only about 20 other instances in the world like it.
