Donald Cline Charges: Fertility Doc Accused Of Using Own Sperm To Impregnate Women

On Monday, retired fertility doctor Donald J. Cline, 77, appeared in an Indianapolis court to face charges over allegedly using his own sperm to impregnate his patients.

Apparently, he had told the women that he was using sperm from medical students, but whenever samples weren't available he used his own.

Suspicion rose two years ago when his now-grown children started researching their heritage.

"It was unethical what he did. He was telling his patients one thing and doing another," says one of his alleged children in an interview with Fox59. "I want to find out as much truth as I can but I know deep down that we never will know the complete truth as to how many siblings we do have."
