Nineteen House Republicans have demanded that the National Institutes of Health immediately halt funding for experiments that subject thousands of laboratory animals to procedures mimicking transgender treatments, despite previous federal assurances that such research had ended.
New Grant Revives Controversial Research
The NIH allocated $584,117 in taxpayer funding this January to a University of California–San Diego project involving nearly 10,000 mice, according to investigations by White Coat Waste Project. Female mice will undergo ovary removal and testosterone injections to model transgender men, followed by skull drilling, brain toxin injections, and decapitation. The grant revives Biden-era research that White Coat Waste first exposed in December 2024, contradicting HHS officials who told reporters in 2025 that no NIH funds currently support transgender animal experiments.

Pattern of Taxpayer-Funded Experiments
White Coat Waste has documented dozens of grants issued during the previous administration funding the creation of transfeminine and transmasculine lab mice, rats, and monkeys. Animals underwent hormone therapies, invasive surgeries, electric shocks, and injections with street drugs and vaccines. Justin Goodman from White Coat Waste stated the records show mice will suffer horrific taxpayer-funded abuse, including invasive surgeries, hormone injections, skull drilling, brain toxin injections, and decapitation. Previous reporting revealed NIH dollars funded transgender monkeys through estrogen administration to male rhesus macaques combined with mRNA vaccine injections.
Congressional Response
Representative Paul Gosar told reporters that tax dollars should not fund sickening transgender animal tests from the previous administration. The congressman confirmed he has been working with White Coat Waste to permanently stop the NIH and other federal agencies from spending money on what he called woke pseudoscience. The lawmakers’ letter cites White Coat Waste investigations showing $8 million in NIH grants have supported transgender experimentation on animals. The revelations come as Americans demand greater accountability for federal research spending and transparency in how tax dollars fund scientific projects.
