Larry Nassar worked at Michigan State University and USA Gymnastics, which trains Olympians. Federal Judge Janet Neff followed the government's recommended sentence Thursday.
Neff says the 54-year-old Nassar "should never again have access to children."
Investigators found more than 37,000 images of child porn on Nassar's electronic devices in 2016. Separately, he has pleaded guilty to molesting gymnasts with his hands in the Lansing, Michigan, area under the guise of treatment.
He'll be sentenced in those cases in January.
