Summary

Donald Trump signed an executive order declaring only two sexes, male and female, based on reproductive cells at conception, banning gender-affirming care, and limiting federal recognition of gender diversity.

Experts, including Dr. Richard Bribiescas, president of the Human Biology Association, criticized the policy as nonsensical, stating, “Clearly, this order is not fully informed by current biological science.”

Biologists noted the order oversimplifies human biology, ignores intersex individuals, and conflates sex and gender.

Critics warned it advances anti-trans rhetoric and risks legal challenges.
