The most children Ever Fathered by One man - 867 Children

The most prolific father of all time is believed to be the last Sharifian Emperor of Morocco, Mulai Ismail (1646-1727). In 1703 he had at least 342 daughters and 525 sons. This is widely considered the record number of offspring for any man throughout history that can be verified. It is thought that Ismaïl would have had to copulate with an average of 4.8 women per day for 40 years to achieve that number of children .link
