A Chinese man is suing for divorce after discovering that he is the father of only one of his twins.
Liu Yuan of Nanjing city says he noticed the difference between the babies the day they were born, reports Longhu Network.
"The baby that came out first was much bigger than the second, who was very weak and sickly," he said.
The dad says he started to be suspicious when the second baby turned out to have a different blood type, paired with the fact that it doesn't look like him.
Liu had his own and the two babies' DNA tested - and discovered that he was the biological father of only the bigger twin.
"My wife admitted that she'd had sex with her former boyfriend after we got married," he said.
Doctors explain that it's quite rare, but possible, since a man's sperm can survive for 72 hours in a woman's body.
Believe it or not, there are actually statistics for this exact situation so it must happen more than most families are willing to admit.
National Georgraphic reports that:
for every 400 sets of fraternal twins, one set is made up of twins who will have different fathers.
