The bill, H.B. No. 3431, seeks to impose strict prohibitions on the provision of gender transitioning or reassignment procedures, treatments, and gender-affirming therapy and counseling for certain children in Texas. It amends the Health and Safety Code by adding definitions and establishing criminal penalties for violations. Specifically, it prohibits physicians and health care providers from performing surgeries that sterilize children, administering puberty blockers or hormones that induce infertility, and removing healthy body parts. Additionally, it introduces penalties for non-physician mental health professionals who provide gender-affirming therapy that affirms a gender inconsistent with a child's biological sex.

Furthermore, the bill prohibits any health care provider from referring children to practitioners in other states for procedures or treatments that would violate the new regulations if performed in Texas. Violations of these provisions are classified as state jail felonies, emphasizing the seriousness of the offenses. The bill is set to take effect on September 1, 2025.
