A woman’s DNA test revealed fertility doctor Charles Peete used his own sperm, deceiving patients and creating multiple affected families.

A 43-year-old woman's 23andMe DNA test, done after years of unexplained blood clots and surgeries, revealed she was not biologically related to her father and had seven half-siblings. This led to the discovery that fertility doctor Charles Peete, active in the 1980s, used his own sperm during treatments, deceiving patients into believing they were using anonymous donors. The revelation exposed a decades-long pattern of medical deception affecting multiple families nationwide.
