A Moroccan man has had a 'nervous breakdown' after discovering that his nine children were fathered by another man.

According to Al Massa newspaper, the Moroccan man discovered he is sterile after 35 years of marriage.

The man has subsequently filed a lawsuit against his wife and has demanded his paternity be removed from their nine children.

Al Massa reported that tests the man took showed he had a growth in his right testes which prevented him from producing sperm.
