This bill aims to prohibit the use of Federal funds for specific gender transition procedures for individuals under the age of 18. It broadly defines these procedures to include various surgeries, such as castration, hysterectomy, mastectomy, and facial feminization or masculinization surgeries, when performed to intentionally change a minor's body to no longer correspond to their biological sex. The prohibition also extends to the administration of puberty-blocking drugs to stop or delay normal puberty, and supraphysiologic doses of testosterone, estrogen, or other androgens. Additionally, it covers the placement of chest implants to create feminine breasts and fat or artificial implants in the gluteal region. However, the bill includes exceptions for medically necessary treatments, such as puberty suppression for precocious puberty with parental consent. It also allows for procedures to correct medically verifiable genetic disorders of sex development or other physical disorders that pose an imminent danger to life or major bodily function, explicitly excluding procedures for the alleviation of mental distress.
