More than 100 former patients of Dr. Larry Nassar are plaintiffs in lawsuits or have filed intent to sue the former Michigan State University doctor over claims of sexual abuse.

Court documents list 84 former patients as plaintiffs. Another 19 women have filed notice of intent to file a legal claim.

In addition, there are 13 parents of minors listed as plaintiffs in the lawsuits.

So far, there have been a total of 10 lawsuits filed by six Michigan law firms and one firm in California.

Almost all of the suits list Michigan State, USA Gymnastics and Twistars, a Lansing-area gymnastics club, as co-defendants, alleging those institutions ignored red flags about Nassar's behavior.

MSU has not yet been served with any lawsuits involving Nassar, MSU spokesman Jason Cody said Tuesday, and he declined comment on potential litigation.

Nearly all of the plaintiffs were adolescents or college-age women when they were treated by Nassar for back, hip and other injuries. The common allegation in the lawsuits is that Nassar's treatments involved vaginal and/or anal penetration without their consent.

The complaints date back to the late 1990s, although some are as recent as 2016.

Among the most recent plaintiffs is a young woman who filed a complaint against Nassar in 2014. The complaint was dropped when investigators determined that Nassar's was performing a legitimate medical treatment.

The breakdown of plaintiffs so far, include:

42 former patients and eight parents of minors are plaintiffs in a lawsuit filed by Stephen Drew and Adam Sturdivant of Drew Cooper and Anding of Grand Rapids. That firm also lists 19 more potential plaintiffs in a March 10 notice of intent to file a claim.

Three women have filed lawsuits in California, and are being represented by John Manly, Vince Finaldi and Alex Cunny of Manly Stewart and Finaldi, a firm based in Los Angeles.

20 former patients and four parents of minors are listed in a lawsuit filed by David Mittleman, Mick Grewal and Nolan Erickson of Grewal Law in Okemos.

15 former patients and one parent of a minor are represented by James White, John Fraser and Alexander Rusek of White Law in Okemos.

Two plaintiffs are being represented by Brian McKeen of McKeen & Associates in Detroit.

One plaintiff is listed in a suit filed by Andrew Abood of the Abood Law Firm in East Lansing.

One plaintiff is being represented by James Graves of Sinas, Dramas, Brake, Boughton & McIntyre, a Lansing firm.

Graves' client, identified by the pseudonym of Jane Doe AAA, was the woman who filed a 2014 complaint with MSU, according to lawsuits.

According to the suit, she is a 2012 MSU graduate and went to MSU's sports medicine clinic in March 2014 to be treated for hip pain.

During the 90-minute appointment, the suit says, Nassar "cupped" the woman's buttocks over her sweatpants; told the woman that her boyfriend should give her "better massages;" asked another doctor who was present to leave the room, and then massaged the woman's breast "despite Plaintiff saying it was not helping her pain in any manner."

Nassar than massaged the woman's vaginal area under her underwear and continued even after "Plaintiff expressly telling him to stop," the lawsuit alleges. Nassar "did not stop touching Plaintiff under she physically removed his hands from her body."

The suit says Nassar became sexually aroused during the exam.

It also says Nassar was "extremely persistent" with trying to set up a second appointment with the woman, even through she rejected a series of dates and times.

The lawsuit says the woman reported Nassar's conduct to Dr. Jeffrey Kovan, then director for the sports-medicine clinic, and Kovan contacted MSU's Office for Inclusion and Intercultural Activities.

The lawsuit says an investigation was conducted by Kristine Moore, an MSU assistant general counsel. According to the lawsuit filing, The investigation determined the woman "did not understand the 'nuanced difference' between sexual assault and appropriate medical procedure and deemed Defendant Nassar's conduct 'was (not) of a sexual nature.'"

Moore and Kovan could not be reached for comment. Those who answered the phone at MSU's sports medicine clinic referred calls to the university's Public Relations department.

The plaintiff said Moore's report did not mention that the patient claimed Nassar was sexually aroused or that she had to physically remove his hands from her body.

After the investigation, Dr. William Strampel, dean of MSU's College of Osteopathic Medicine, issued a written directive in which Nassar was told that during exams "close to a sensitive area," Nassar needed to have a third party in the room, explain the procedure and limit skin-to-skin contact.

When Nassar was fired in 2016, the official reason stated was failure to follow those directives.

On March 17, MSU's Office for Institutional Equity issued the results of a Title IX investigation into a complaint filed last August by Rachael Denhollander, who was treated by Nassar in 2000 when she was 15.

That investigation found a "preponderance of evidence" supported Denhollander's allegations that she was sexually abused by Nassar under the guise of medical treatment.

In addition to Michigan State, USA Gymnastics and Twistars, the suits filed by the Grewal and Abood firms also lists five individual as co-defendants: Kovan; Strampel; Kathie Klages, who recently retired as MSU women's gymnastics coach; Dr. Gary Stollak, a retired professor in clinical psychology, and John Geddert, who owns Twistars.

Nassar is currently in federal custody for alleging have child porn on his computer. He also is facing 25 counts of first-degree criminal sexual conduct involving 10 women.

More than 80 women have filed criminal complaints against the former doctor, and those cases are under investigation by the MSU Police Department.
