Judge Rosemarie Aqualina told Nassar during the sentencing he will "be in darkness the rest of his life".
"As much as it was my honour and privilege to hear the sister survivors, it was my honour and privilege to sentence you. Because, sir, you do not deserve to walk outside of a prison ever again," she said.
She added that she would not send her dogs to the former sports doctor, adding: "I've just signed your death warrant".
