Thirty-five women are suing a Beverly Hills obstetrician-gynecologist, Cedars-Sinai Medical Center and other medical practices where the doctor worked, alleging decades of sexual and medical misconduct that the health facilities enabled and concealed.

The lawsuit, filed late Monday in Los Angeles County Superior Court, alleges that Dr. Barry Brock had, for years, made lewd and unsettling comments to patients; groped their breasts and genitals during medically unnecessary exams, sometimes without gloves; and engaged in “female genital mutilation” by giving women unneeded sutures, among other reported misconduct.

The suit also alleges the longtime physician denied caesarean sections to patients who needed them.

Brock has repeatedly denied any wrongdoing or sexual misconduct, saying he had never touched a patient inappropriately or made sexually suggestive or harassing remarks.

The longtime OB-GYN said in a statement Tuesday that the allegations in the lawsuit were false and outrageous, calling them “flat-out lies, made up events that never happened, exaggerated and fabricated statements, and worse.”

Attorneys “have made it seem as if I was grooming patients even by just speaking to them, insanely claiming that suturing a patient after childbirth is genital mutilation, and saying that my standard vaginal exams and pap smears were ‘sadistic,’” Brock said.

He said that patient records and witnesses “will help me prove the truth of what happened here.”

Cedars-Sinai said in a statement Tuesday that the kind of behavior alleged about Brock, who is no longer practicing medicine at its facilities, is “counter to Cedars-Sinai’s core values and the trust we strive to earn every day with our patients.”

“We recognize the legal process must now take its course, and we remain committed to Cedars-Sinai’s sacred healing mission and serving our community.”  

The doctor is also facing an accusation before the Medical Board of California, where he is accused of committing “repeated negligent acts.” According to the official complaint, Brock failed to give a patient enough pain medication while treating her for a miscarriage, and failed to properly clear material from her uterus, among other accusations.

In a statement, Brock said the events outlined in the accusation were not an accurate description of his treatment of the patient and that some allegations were “completely inconsistent with my practices.”

For instance, Brock said he could not imagine refusing to address severe pain suffered by a patient. “Based on what I know of my care and treatment of this patient,” he said, “I will successfully defend my treatment as being within the standard of care.”

Brock, 74, said he had been an attending physician at Cedars-Sinai since the early 1980s, and had never before faced an accusation from the medical board.

He left its physician network in 2018 but retained hospital privileges at Cedars-Sinai while working in private practice at Rodeo Drive Women’s Health Center and Beverly Hills OB/GYN, which were also named as defendants in the lawsuit. Both organizations had yet to respond to requests for comment Tuesday.

In July, Cedars-Sinai said it had suspended Brock’s hospital privileges after receiving “concerning complaints” from his former patients. A few months later, his hospital privileges were terminated.

At that time, a spokesperson for Cedars-Sinai said that privacy laws prohibited the medical center from confirming the existence of any patient complaints or disciplinary action taken against Brock before this year.

The lawsuit alleges that both patients and medical staff reported concerns about Brock to Cedars-Sinai long before the complaints that led to the termination of his hospital privileges.

Cedars-Sinai administrators received “ample and repeated warnings” about his misconduct and abuse of patients through past lawsuits, as well as complaints to the state medical board and to the health system itself, the lawsuit alleged. Yet the medical center and other defendants continued to “expose more unsuspecting female patients to a known serial sexual predator,” the suit alleged.

Plaintiffs are represented by a legal team that includes Anthony T. DiPietro, an attorney who has also represented patients of convicted sex offender Robert Hadden, formerly a gynecologist at Columbia University, and Mike Arias, who like DiPietro has represented patients of former USC gynecologist George Tyndall.

The complaint details allegations from 35 former patients ranging in age from their 20s to their 60s. Some saw Brock only once and refused to see him again, while others were treated by him repeatedly over a period of years. The timing of their care ranges from the mid-1980s to this year, according to the complaint.

Nearly a dozen patients alleged unnecessary suturing or crude comments about it: Brock told several plaintiffs he inserted an “extra stitch” in their perineal areas to make them “tighter” after childbirth, the lawsuit said.

In one instance, according to the lawsuit, Brock said, “I’m going to sew her up virgin-tight” in front of a woman’s husband and parents after childbirth. In another, Brock told a woman that she had not suffered any tearing, but told her husband, “Don’t worry, dad, I’ll throw a stitch in there for you,” and proceeded to suture her without her consent, the lawsuit alleged.

Some suffered ongoing pain or urinary complications after “this barbaric and entirely unnecessary form of female genital mutilation,” the lawsuit said. Doctors for one patient described the stitching as “the equivalent of a female circumcision,” the lawsuit said.

Brock told The Times that he performed perineal suturing only if there was a laceration, and that if he did so, “there was always consent.”

The lawsuit also included allegations of violent and threatening behavior. One former patient alleged that Brock “violently thrust” a speculum into her vagina, opened it and “proceeded to pump the instrument in and out of her, simulating intercourse.”

The woman said she reported the experience and other concerning encounters with Brock to an executive at Rodeo Drive Women’s Health Center, where Brock worked at the time. No action was taken against him, according to the lawsuit.

Brock told The Times that he had never forced in a speculum and called the claim about simulating intercourse “complete nonsense” that “appears to be a tricky lawyer way to make an appropriate medical exam seem like an assault.”

In the lawsuit, two women alleged that he forced them to feel his erection. One said he had “proceeded to rub his erect penis against her hand” while she was alone with him in an exam room, the lawsuit said.

Another alleged that while she was in labor, Brock walked in and put her foot on his erection, then grabbed her foot again when she tried to move it away.

Brock, in his statement, said he had “NEVER NEVER told any patient to touch me in any way,” nor touched patients inappropriately, and had never had an erection during an exam.

The lawsuit also alleged that Brock forced patients to undergo sensitive physical exams even after they refused. A decision to do a pelvic or breast exam should be a shared one between a physician and a patient, the lawsuit said, and “such invasive procedures should never be performed without the patient’s knowledge, understanding, and consent.”

In one case, the lawsuit said, Brock pulled down the pants of a woman who refused a vaginal examination in front of her daughter and “was so aggressive that [the woman] immediately ran out of the room in tears.”

Brock, in his statement, denied ever pulling down the pants of a patient and said that if a woman wanted to refuse a Pap smear or pelvic examination, that would be her right. He also said he always wore gloves to protect himself and patients during pelvic exams.

Another patient alleged that Brock ignored her when she said a breast exam was unnecessary. Instead, the complaint alleges, he unhooked her bra, squeezed her breasts and told her, “You have perfect breasts. Does your husband tell you that?” She was one of five women who said he removed their bras without consent before touching their breasts, according to the complaint.

Other patients alleged that Brock refused to leave the room as they undressed or denied their request for a hospital gown, requiring them to go through examinations naked.

Brock told The Times that he either leaves the room when a patient undresses or, if a patient in a hurry requests it, turns while they change behind a curtain, and “there never would be a case where a gown was not provided upon request.” He said if a patient turned down a breast exam, he would not perform one.

The doctor added that on a few occasions when a patient had not removed their bra before putting on a gown, he had assisted a patient in unclasping it for a breast exam. “This was not done for any improper purpose and was done that way so the patient did not need to take off the gown,” Brock said.

In the lawsuit, many patients described sexual remarks: One said Brock told her that her vagina looked “ripe” and peppered her with invasive questions, such as asking whether her partner would ejaculate on her body during sex, according to the lawsuit. Several patients noted that while examining the women’s genitals or breasts, Brock commented on how “lucky” or “happy” their partners must be, the suit said.

Brock denied making such remarks. “I have never spoken those words,” he said.

The lawsuit alleges that Cedars-Sinai was repeatedly informed about concerns with Brock. One patient who saw him between 2011 and 2013 reported his behavior to office staff and asked to switch to a different doctor, according to the lawsuit. Another who saw him in 2018 and 2019 informed her regular physician, who was also affiliated with Cedars-Sinai, about his actions, the suit said.

Another former patient, herself an employee of Cedars-Sinai at the time, filed a formal complaint with the medical center after a 2017 prenatal appointment in which Brock allegedly groped her breasts “under the guise of medical care” and made inappropriate comments to her and her husband, according to the suit.

Though she was told there would be consequences for Brock — who was in Cedars-Sinai’s physician network at the time — she heard nothing more from the medical center, the complaint states.

The lawsuit said another patient who tried to report misconduct to Cedars-Sinai earlier this year was initially told that the medical center wouldn’t take action because the doctor was in private practice.

She then contacted Beverly Hills OB-GYN, which had referred her to Brock after her usual physician was unavailable. When she received no response after sharing her experience, the woman lodged a formal, written complaint with Cedars-Sinai by email, according to the suit. It was only then, the lawsuit said, that her complaint was taken seriously and Brock had his hospital privileges suspended.

A Cedars-Sinai spokesperson told The Times in September that the hospital system had terminated clinical privileges for Brock after an investigation and reported the matter to the state medical board.

Brock, however, said he had surrendered his privileges without any “fact finding” or “hearing on the merits” of the allegations under investigation. In August, he had informed patients he would retire at the end of the month due to the “uncertainty of how long this process will take.”

On Tuesday morning, Princeton University professor John Hopfield and University of Toronto professor Geoffrey Hinton won the Nobel Prize in Physics 2024 for their foundational discoveries and inventions that pioneered modern artificial intelligence.

Hopfield joined Caltech as faculty in 1980 and, two years later, published his seminal paper in which he applied principles of the brain to computer circuits, creating a neural network able to hold memory and recognize patterns.

Building off of Hopfield’s network, Hinton created a model that could not only distinguish between different patterns or images, but generate new ones altogether. His development later landed him a job at Google after the tech giant bought his company.

“These artificial neural networks have been used to advance research across physics topics as diverse as particle physics, material science and astrophysics,” said Ellen Moons, chair of the Nobel Committee for Physics, at the announcement. “The laureates discoveries and inventions form the building blocks of machine learning.”

The researchers will split a prize of roughly $1 million.

Hopfield was recruited to Caltech in 1978 after the university appointed a new president with a background in physics.

After years of attempting to model the human brain, Hopfield finally made his breakthrough in early 1980. He called Caltech a “splendid environment” for testing out his various ideas.

Around the same time, Hinton had left UC San Diego for Carnegie Mellon in Pittsburgh, where he developed his model based on Hopfield’s.

Called the Boltzmann machine, the model formed the basis of current generative AI models like ChatGPT (the “G” stands for “generative”).

Hinton and two of his students created a company based on the research in 2012, focused on using AI to identify common objects in photos, like flowers and dogs. Shortly after, Google bought it at auction for $44 million.

Hinton quit his job at the tech giant in 2023 so he could publicly voice concerns about the technology he helped invent.

He fears people will no longer be able to distinguish AI-generated images and videos from real ones and opposes the use of AI on the battlefield. Hinton said a part of him regrets his life’s work.
