A teenage mum of twins who did a paternity test on them was astonished to find the babies were from two different men, both of whom she had slept with on the same day.
The young woman, who asked to remain anonymous but who is aged 19, said she wanted to confirm who the father was, which was why she decided to take a paternity test, and she was amazed by the results, saying: “I didn’t know this could happen.”
Her doctor said that her case is an extremely rare, “one in a million” situation.
The unusual case, of which there are reportedly only about 20 others in the world, happened after the teen had sex with both men on the same day and became pregnant from both of them, according to local media.
The young woman, who preferred to remain anonymous but who is from the municipality of Mineiros, in the state of Goias, in central-western Brazil, reportedly said: “I was surprised by the results. I didn’t know this could happen. They are very similar.”
Her doctor, identified as Tulio Jorge Franco, confirmed that her case was very rare and that there are only around 20 other cases worldwide of so-called heteroparental superfecundation, as it is known scientifically.
The doctor reportedly said: “It is possible to happen when two eggs from the same mother are fertilised by different men. The babies share the mother’s genetic material, but they grow in different placentas.”
The young woman reportedly explained that her babies look very similar but after eight months, doubts began to emerge about who the father was. So when they were eight months old, she got DNA from the man she thought was the father.
But the test only came back as a positive match for one of her two children.
She did the test again but the result was again positive for just one child.
That is when she remembered that she had had intercourse with another man that day. She said: “I remembered that I had had sex with another man and called him to take the test, which was positive.”
The babies are now 16-month-old tots but the case was only revealed by the doctor this week, according to local media.
The mum said that one of the two men is doing the responsible thing, officially registering at the registry office and taking care of both children. The teenage mum said: “He takes care of both of them, helps me a lot to create and gives them all the necessary support they need.”
Tulio Franco added: “It’s extremely rare. It’s one in a million. I never imagined that I would see a case like this in my life.”
