Research suggests that, as cases of teenage pregnancies, sexual infidelity and multiple partners increase, 1 in 25 fathers could unknowingly be raising another man's child.
With improvements in genetic testing, thousands of fathers every year are discovering that “their” child is someone else's. A study by scientists from Liverpool John Moores University concludes that 4 per cent of all men are unwittingly bringing up a child they have not fathered.
Of the men who demand a paternity test because they suspect infidelity, one in four have their suspicions confirmed.
The team gives warning that the trend, known as “paternal discrepancy”, poses serious implications for the future of the family.
