For those who have yet to see the documentary, it follows Jacoba Ballard, who, after taking an at-home fertility test, discovered that she had dozens of half-siblings whose mothers had visited Donald's clinic.
Once described as the "best infertility doctor in Indianapolis", Donald had hopeful parents-to-be come to his clinic in their droves in the hopes of receiving top treatment. Unbeknownst to them, he was using his own sperm to inseminate his patients and is thought to have fathered anywhere from 50 to 90 children between 1979 and 1986.
Our Father is available to stream on Netflix.
