A man has been put on trial accused of keeping his daughter as a sex slave for 20 years and having eight children with her.
A DNA test allegedly showed that Argentine Domingo Bulacio, 56, was responsible for his daughter's eight pregnancies after repeatedly raping her.
Bulacio was eventually arrested after the woman took her youngest son to the doctor, the MailOnline reported.
The doctor asked who the boy's father was and she told him the truth about his parentage.

Bulacio was taken into custody in January 2016 after fleeing police for 45 days.
He was discovered hiding 30 miles away from his hometown at a relative's house in Loreto, Santiago del Estero, northern Argentina.
After undergoing the DNA test, Bulacio was charged with sex crimes and will now stand trial.
According to local reports, the victim was abandoned by her mother, who was allegedly physically abused by Bulacio.
Six of the eight children are living at the boarding school of Eva Peron in Santiago del Estero, local media reported.
There is no further information about the mother, whose name has not been made public.
The case, which has been adjourned until next week, continues.
