TX HB1559

Prohibits physicians from performing medical procedures or treatments related to intersex traits on foster children unless the procedure is medically necessary and the child consents, or if not medically necessary, the child consents and a court authorizes it

Defines "intersex trait" as inborn chromosomal, gonadal, genital, or endocrine characteristics atypical for male or female definitions; covered procedures include hormonal treatments and various genital surgeries such as clitoroplasty, vaginoplasty, hypospadias surgery, and gonadectomy

Establishes detailed informed consent requirements including physician disclosure of risks (loss of reproductive capacity, sexual function), mental health professional evaluations on at least two occasions, and written consent documentation

Requires court hearings for non-medically necessary procedures where the child must be represented by an attorney with knowledge of intersex issues; for children under 12, the attorney or guardian ad litem must argue against non-medically necessary procedures

Courts must determine best interest based on clear and convincing evidence that physical and psychological benefits outweigh risks, considering impacts on fertility, future development of sex characteristics, and bodily autonomy
