Netflix's latest true crime offering Our Father gives viewers an insight into the truly gruesome story of fertility doctor Donald Cline.
Cline was a once-respected fertility doctor from Indianapolis in the US, who is believed to have artificially inseminated over 50 women with his own sperm in the 1970s and 80s.
He opened a clinic in 1979, and secretly impregnated the women with his own sperm, while claiming they were from donors.
