The U.S. Department of Health and Human Services (HHS) under Secretary RFK Jr. has issued new federal guidance recognizing only two sexes - male and female - aligning with recent Trump administration policies.

The February 19 guidelines define sex as "a person's immutable biological classification," eliminating previous gender-inclusive language. The definitions specify:

  • Female/Male based on reproductive system function
  • Woman/Man as adult humans of respective sexes
  • Girl/Boy as minor humans of respective sexes
  • Mother/Father as female/male parents

Medical experts strongly oppose these changes, noting they:

  • Contradict scientific understanding of sex and gender
  • Ignore intersex individuals (estimated 1.7% of population)
  • Disregard variations in sex characteristics including:
    • Chromosomal differences (XXX, XXY, XXXY)
    • Gonadal variations
    • External genitalia diversity
    • Secondary sex characteristics

Healthcare Impact:

  • Disrupts access to gender-affirming care
  • May increase health risks including:
    • Osteoporosis
    • Cardiovascular disease
    • Cognitive decline
  • Creates barriers to appropriate medical treatment
  • Affects mental health outcomes

Mental Health Consequences:

  • Increases discrimination against LGBTQ+ individuals
  • Elevates risk of depression and suicide among affected populations
  • Creates fear and uncertainty in transgender and gender-diverse communities
  • Impacts youth mental health and well-being

The policy changes have already affected federal documents, sports participation, and healthcare access across multiple states, raising concerns among medical professionals about long-term physical and psychological impacts on affected communities.
