A retired Indianapolis fertility doctor used his own sperm to impregnate at least eight mothers decades ago and admitted to six now-adult children to doing so, court documents say.
Dr. Donald Cline faces two felony obstruction of justice charges for misleading authorities who were investigating two of the children's complaints against him.
He surrendered in court on Monday.
The 77-year-old suburban Zionsville man told the six adults that he had donated his own sperm about 50 times, a probable cause affidavit says.
His patients were told they were receiving sperm from medical residents or students.
Cline is accused of being the biological father of at least eight people. The youngest would be about 30.
The six adults conceived through Cline's clinic in the 1970s and 1980s discovered they were siblings born to the same biological father through online DNA tests, Fox59 reported.
The siblings met with Cline in the spring of this year and he told them that he had used his own sperm when a donor was not available, according to court documents.
He also told them that he had kept records of which patients received his sperm but all of those have since been destroyed since Indiana only required medical records be kept for seven years.
He didn't consider himself to be fathering children, but helping families unable to conceive, Cline said in an interview with Fox.
His attorney is expected to release a statement on Monday afternoon.
He was released on his own recognizance and a hearing is scheduled for next month.
