Netflix releases the trailer for Our Father, about a former fertility doctor who used his own sperm to inseminate patients

The documentary, premiering May 11, follows former fertility doctor Donald Cline, who admitted to using his own sperm to impregnate unsuspecting patients more than 50 times throughout his career. As E! News notes, "the most unsettling part about Our Father is that it's just the latest in a line of documentaries with eerily similar subject matter."
