Updates: Campaign to End Deadly Marmoset Experiments at the University of Massachusetts–Amherst

At the University of Massachusetts–Amherst (UMass), experimenter Agnès Lacreuse drills holes into the skulls of small marmosets, threads electrode leads through their abdomens, zip-ties them into restraining devices, and overheats them with hand warmers to simulate hot flashes associated with menopause—which they don’t even experience naturally. PETA is urging the university to ditch these crude and painful tests—and you can help.

UMass President Confronted by Monkey Defender at Alumni Event Outside Arizona Cardinals’ Stadium

December 12, 2022

As UMass President Marty Meehan arrived at an NFL pregame alumni reception at the Arizona Cardinals’ State Farm Stadium in Glendale, Arizona, a PETA supporter asked him why he continues to allow the torturous menopause experiments on tiny monkeys who don’t naturally experience the transition. Meehan conveniently shifted the blame by explaining that he doesn’t make any decisions regarding experiments, claiming that it’s the responsibility of the chancellor. As the president was asked about the millions of dollars the university has received for the junk science experiments, security guards swarmed the advocate, who was knocked to the ground. At one point, a security guard pulled on the advocate’s shirt so hard that it ripped. Watch the video here.


PETA Supporters Detained After Confronting UMass Experimenter Agnès Lacreuse

November 16, 2022

Monkey advocates invaded the University of Michigan’s Pharmacology Seminar Series, where they confronted experimenter Agnès Lacreuse, interrupting her seminar titled “The Marmoset as a Model for Neurocognitive Aging and Women’s Health Research.” As Lacreuse began discussing the gruesome menopause experiments that she conducts, a PETA supporter stole the show and the mic to address Lacreuse as a “model of failed science.” The UMass experimenter shouted at the animal advocates that her “marmosets are very happy” and that her “studies are ethical,” but the torture and killing that every marmoset endures in her lab tell a vastly different story. Watch the video footage here.


Elvira Condemns Cruel Experiments on Marmosets

October 31, 2022

Elvira, Mistress of the Dark—whose real name is Cassandra Peterson—is shedding some light on a real-life house of horrors. The actor, feminist hero, and longtime PETA ally has just sent a letter to University of Massachusetts–Amherst Chancellor Kumble Subbaswamy, urging him to pull the plug on lethal marmoset experiments that purportedly study menopause—which, unlike Peterson, the animals don’t even experience naturally.

“Maybe I’m just having a hot flash, but this cruel waste really makes my blood boil,” she writes. “And it has cost taxpayers $4.4 million. Seriously? This all sounds like a horror film cooked up during a night sweat. . . .

“Menopause is not for the weak. Believe me, I’ve been through it and I know,” she continues. “But it’s not for monkeys, either. These experiments could be done in a kinder, more human-relevant way by studying women who actually experience menopause.”

Second Attempt by UMass to Silence Monkey Advocates During Homecoming Week Fails

October 29, 2022

UMass’ attempt to thwart PETA from speaking out against the deadly menopause experiments during Homecoming week has failed for two years in a row now. UMass officials informed PETA that we weren’t allowed to protest at a Homecoming event again this year, but donors attending the Chancellor’s Donor Appreciation Breakfast were still welcomed by animal advocates handing out leaflets. In addition, the entrance to the building where the breakfast was being served was lined with stuffed marmosets in cages symbolizing the dozens of marmosets imprisoned in a UMass laboratory. The donors were grateful to see supporters raising awareness of the cruel monkey experiments, and many of them thanked us for being there.

The New York Post debuted the story and the disturbing video of Rey, a monkey who was imprisoned in Agnès Lacreuse’s laboratory. Read the full article here.

The Daily Hampshire Gazette ran a beautifully written op-ed by Sheryl Becker, president of Western Massachusetts Animal Rights Advocates.

October 18, 2022

On World Menopause Day (October 18), a day to raise awareness of menopause, we released this stunning new infographic that highlights the absurdity and cruelty of the menopause experiments on monkeys conducted by University of Massachusetts experimenter Agnès Lacreuse.

Speak up for the monkeys imprisoned in her laboratory.


PETA Slaps UMass With Lawsuit for Attempting to Hide Public Records

September 13, 2022

UMass is trying to keep the public in the dark about the grisly marmoset monkey experiments being conducted in experimenter Agnes Lacreuse’s laboratory, going as far as refusing to provide public records that PETA requested. PETA filed a lawsuit with Suffolk County Superior Court in Massachusetts to demand transparency of the taxpayer-funded experiments, including videos of monkeys in stressful social separation tests and a video in which hand warmers are forcefully held on the monkeys’ abdomens. Read more here.


Brand-New UMass Students Shown the Truth About Monkey Tests on Campus

Students were disgusted to hear about the experiments being conducted at their new university and were eager to learn more about how they could help end the monkeys’ suffering.


PETA Activist Confronts UMass Chancellor About Monkey Experiments

September 3, 2022

Immediately following Chancellor Kumble Subbaswamy’s free-speech presentation on campus, an activist asked him why he had abruptly shut down talks with PETA scientists about ending the university’s gruesome menopause monkey experiments and shifting to a human-relevant, animal-free research program. Subbaswamy had the chance to practice what he preaches, but he refused to discuss the matter. It appears that when experiments rake in over $4 million in taxpayer funds, the chancellor stops caring about free speech. See his reaction here.

PETA Depicts Menopause Monkey Lab: The Dark Side of UMass

August 18, 2022

There’s a dark side to UMass, where greed, secrecy, and killing abound. UMass experimenter Agnès Lacreuse was pulled into it, like a real-life Darth Vader. There’s no doubt the tiny marmoset monkeys, whom she named after Star Wars characters, viewed her as a villain when she drilled into their skulls, cut them open, and forced hand warmers onto their bodies before killing them. Read the full story of Anakin, a marmoset imprisoned and killed in the UMass lab, here.

‘UMass Chancellor, Retire the Monkey Lab on Your Way Out,’ Says PETA

June 30, 2022

Following the announcement that UMass Chancellor Kumble R. Subbaswamy will retire in June 2023, PETA has urged him to retire the school’s shameful marmoset monkey laboratory, too, and release the monkeys to reputable sanctuaries.

Great News! UMass Apparently Nixes Request for Monkey Sleep-Deprivation Experiments

February 8, 2022

Could UMass finally have had enough sense to say NO to one of experimenter Agnès Lacreuse’s heinous experiments? Let’s hope so.

May 19, 2021
