US health agency revises definitions of male and female to align with Trump order

The U.S. Department of Health and Human Services has updated its definitions of male and female, aligning with President Trump's executive orders. The new guidance states that sex is determined genetically at conception and cannot be changed. This update is one of the first actions by Robert F. Kennedy Jr. since becoming Secretary of Health and Human Services. It emphasizes a binary view of sex, contrasting with previous policies that supported broader definitions of gender. The guidance also mentions compliance with another Trump order aimed at preventing certain medical treatments for children, referred to as "gender-affirming care." A federal judge has temporarily blocked enforcement of this order.
