A 19-year-old girl gave birth to twins, who turned out to be children of two different fathers. According to Brazilian media reports, the incident happened in Mineiros in the southwest of Goiás, Brazil. The young woman noted that as the children grew older, although they remained very similar, they developed some aesthetic differences. This prompted Mom to request a DNA test from the man she believed to be the father. Then the discovery: the man was not the father of both twins.
At this point, the woman recalled having a casual relationship with a friend. “I remembered having sex with another man and called him to take the test, which was positive” – were the words of the young woman. it was dr Túlio Franco, the gynecologist who accompanied her throughout her pregnancy, who explained to her what had happened medically. This is a case of heteropaternal super-fertilization, which can occur when the mother releases multiple eggs and when she has intercourse with two males at the same time. So far, only twenty cases are known worldwide. “It happens to one in a million people.”
However, learning that he is not the father of either child was not a problem for the young woman’s partner, who is raising them both as if they were both his biological children.
