The case against Nassar has sparked various investigations into why the U.S. Olympic Committee, the sport's governing body USA Gymnastics, and Michigan State University, where he also worked, failed to investigate complaints about him going back years.
High-level officials at USA Gymnastics and Michigan State have resigned in recent weeks as outrage over the scandal intensified.
Nassar, who is also serving a 60-year federal sentence for child pornography convictions, pleaded guilty to two sets of molestation charges in Michigan's Ingham and Eaton counties and had to be sentenced in each case.

As Eaton County Circuit Judge Janice Cunningham delivered Nassar's sentence on Monday, several victims in the courtroom cried. Rachael Denhollander, the first woman to make her allegations of abuse public, smiled broadly and squeezed her husband's hand.
After Nassar was led out in handcuffs, a parade of victims lined up to hug and thank Denhollander.
As with last month's proceeding in Ingham County, Monday's sentencing followed days of testimony from scores of Nassar's victims, who offered emotionally wrenching accounts of his abuse masquerading as medical treatment, sometimes with their own parents present in the exam room.
More than 260 women and girls say he abused them while working with the gym, Michigan State University and USA Gymnastics.
Ms Denhollander said after Monday's sentencing that victims that "there is nothing I can do to help Larry Nassar."
"There is something I can do regarding the institutional dynamics, and that's where my focus will be," she said.
Fellow survivor Larissa Boyce said following the sentencing hearing in Charlotte, Michigan, that a chapter is closed, while Katie Black said she felt "almost a sense of closure and that this is all over and things are going to be taken care of."
Nassar offered a brief apology to his victims on Monday, saying, "The visions of your testimonies will forever be present in my thoughts."
But the judge, Janice Cunningham, said Nassar had again suggested in a pre-sentencing interview with authorities that he had not done anything wrong, even after he was sentenced in Ingham County.
