Nancy Mace, a South Carolina Republican, criticized the Biden administration for allocating more than $10 million in taxpayer funds for what she described as ‘painful and lethal transgender experiments’ conducted on mice.
According to Ms Mace, the experiments ‘forced lab animals to undergo invasive surgeries and hormone therapies.’
During a recent hearing, she presented findings from the White Coat Waste Project, which disclosed that the NIH had granted over $240 million for experiments on transgender animals. This included $26 million in current funding specifically for research on the impacts of feminizing and masculinizing hormones in mice.
In her opening remarks, Mace remarked, ‘The Biden-Harris Administration was so keen on promoting their extreme gender agenda throughout all sectors of American society that they failed to recognize that these experiments are not only inhumane but also unnecessary.’
The research sought to understand how hormones might influence wound healing, how gender-affirming hormone therapy impacts the immune system, reproductive function, and heart health.Â
Early stages of research like this are often conducted in mice because they share many genetic similarities with humans, making them a comparable model for studying human biology.
There’s no sign of grant funding being revoked, but the Trump administration aimed to cut the NIH’s budget.
President Trump’s federal spending freeze initially disrupted NIH grants but was quickly reversed due to confusion.

Rep Mace said in an Oversight Committee hearing titled ‘Transgender Lab Rats and Poisoned Puppies: Oversight of Taxpayer Funded Animal Cruelty,’ that the Biden administration had allowed taxpayer dollars to fund ‘surgically mutating animal genitals.’Â
The studies identified by White Coat Waste received grant funds for a wide range of amounts from $48,000 to over $3million.Â
Justin Goodman, WCW’s senior vice president of advocacy and public policy, said the true totals are actually much higher: ‘Some of these tests examine the effects of sex party drugs or the impact of hormones used for human gender transitions on the size and shape of lab animals’ genitals.’
The study with the most funding on WCW’s list explored how estrogen influenced lung inflammation caused by asthma by administering hormones to mice.Â
The intended purpose was to understand the sex-specific effects of estrogen in asthma, with the goal of developing personalized treatments for women.
Another study, which received $1.1million in grant funding, investigated how sex hormones affect the way GHB – a rave drug popular among the LGBTQ+ community – is processed in the body.Â
The intended purpose was to better understand how sex hormones influence the transporters in the body that affect GHB’s clearance and toxicity.
Mice constitute around 95 percent of laboratory animals used in research, ranging from studies on gender transition treatments to potential cancer cures and heart disease drugs.
It is standard for any experimental medication to undergo animal testing, but while scientists can give mice hormone treatments to study biological effects, this does not make them ‘transgender’ in the way humans use the term.

Rep Mace cited another study in which ‘federal funds were also used to forcibly transition male monkeys to see if hormone therapy made them more susceptible to HIV.
‘Monkeys cannot be infected with HIV. Yet this federally funded experiment forced them to take hormone-altering drugs to study a virus they cannot have.’
Monkeys cannot be infected with HIV – human immunodeficiency virus – but they can be infected with SIV – simian immunodeficiency virus – which is a well-established model for studying HIV in humans.
Research on SIV has helped scientists better understand HIV transmission, progression, and treatment.
There is no indication that grant funding will be rescinded or the research stopped, but the Trump administration has pledged to slash the NIH’s funding.
When President Donald Trump gained office, he issued a sweeping freeze on federal spending, which upended the NIH’s grant-making process.
Given the confusion it caused, however, the president quickly walked back the freeze.Â
