Following seven days of emotional testimony from Nassar's victims, he was given an opportunity to address the court.
"What I am feeling pales in comparison to the pain, trauma, and emotional destruction that all of you are feeling," he told the packed courtroom.
"There are no words to describe the depth and breadth of how sorry I am for what has occurred," he added.
A story of survival

Throughout the seven-day hearing, the stories have been strikingly similar - the former USA Gymnastics team doctor would call the women in for treatment, but instead of taking away their pain, he stole their innocence. Some were so young they didn't realise until years later that they had been sexually abused.
As Larry Nassar sat in his prison overalls, just metres away from them, survivor after survivor looked him in the eye and reminded him of what he'd done to them. And that's been the most extraordinary thing about this hearing.
While the content of their testimony has been harrowing, it's also been inspiring. For survivors of sexual abuse it's hard to relive the experience, let alone do so in front of your attacker.
