Relating to prohibitions on the provision to certain children of gender transitioning or reassignment procedures and treatments and gender-affirming therapy and counseling; creating criminal offenses.

HB 3431 prohibits physicians from performing specific surgeries (like hysterectomies, orchiectomies, or genital surgeries) or providing certain medications (including puberty blockers or supraphysiologic hormone doses) to minors for gender transition purposes. It also bans non-physician mental health professionals from providing gender-affirming therapy or counseling to minors if the goal is to affirm a gender inconsistent with the minor’s biological sex (determined by sex organs, chromosomes, and endogenous profiles). Violations would be classified as state jail felonies. The bill directly affects transgender and gender-diverse minors seeking medical or mental health care, as well as healthcare providers and therapists. It amends Texas Health and Safety Code Sections 161.702 and 161.7035.
