A retired Indianapolis fertility doctor accused of inseminating patients with his own sperm is set to plead guilty to charges that he lied to investigators.
Dr. Donald Cline, 79, is scheduled to appear Thursday afternoon in a Marion County court, when a judge is expected to sentence him on two counts of obstruction of justice. The charge carries a sentence of six months to three years in prison.
Some of the now-adult children of Cline's former patients filed a complaint with the Indiana attorney general's office in 2014 after they became suspicious that Cline had inseminated some of his patients with his own sperm.
Cline, who retired in 2009, initially wrote to investigators denying the allegations.
Paternity tests indicate Cline is likely the biological father of at least two of his patients' children, according to court records. Those children allege that online genetic tests show he may be the father of 20 others.
According to prosecutors, Cline told six adults who believed they were his children that he had donated his own sperm about 50 times starting in the 1970s, according to court documents when he was charged last year. He had told his patients they were receiving sperm from medical or dental residents or medical students and that no single donor's sperm was used more than three times.
No other charges were filed against Cline because Indiana doesn't specifically prohibit fertility doctors from using their own sperm.
A prominent instance in which a fertility doctor secretly used his own sperm was Cecil Jacobson, who may have fathered as many as 70 children from 1976 to 1998 in Vienna, Virginia.
