An extremely rare case of twins born from two different fathers was revealed on Tuesday, 8th of March 2016 by the sanitary authorities of Vietnam. The discovery was followed upon a test DNA made on these twins in a laboratory in Hanoi, at the request of their parents, the identity of whom was not revealed.
The rarity of this phenomenon was underlined. Indeed, the latter occurs when two oocytes of the mother are fertilized by two different men, during sexual intercourse arisen during the same period of ovulation. The number of pairs of twins identified born from different fathers is estimated at about ten worldwide.
According to the daily Tupi Tre, everything started from a request of a paternity test asked by the official father, worried about verifying if he was the biological father of the two twins of his wife because one of them seemed to have no family resemblance. The tests showed that he was the father of only one of the two babies, while his wife is he biological mother of both children, today two-year-old.
