Texas Attorney General Ken Paxton has filed a lawsuit against Dr. May C. Lau, a physician from the Dallas area, for allegedly violating Texas law by administering prohibited “gender transition” treatments to nearly two dozen minors.
The lawsuit highlights a breach of Senate Bill 14, which took effect in September 2023 and was upheld by the Texas Supreme Court in June 2024. This legislation prohibits medical interventions such as surgeries, puberty blockers, and cross-sex hormones for minors seeking to transition their biological sex. Evidence has increasingly suggested that such treatments, prescribed to children, may have irreversible and damaging long-term effects, with many being classified as experimental and lacking scientific support for their benefits.
According to the Office of the Attorney General, Dr. Lau provided high-dose cross-sex hormones to twenty-one minor patients, allegedly using false diagnoses and billing codes to conceal the nature of these prescriptions. Texas law mandates that the Texas Medical Board must revoke the medical license of any physician found in violation of these provisions.
“Texas passed a law to protect children from these dangerous unscientific medical interventions that have irreversible and damaging effects,” Attorney General Paxton stated. “Doctors who continue to provide these harmful ‘gender transition’ drugs and treatments will be prosecuted to the full extent of the law.”
Texas law prohibits surgeries, puberty blockers, and cross-sex hormones for the purposes of transitioning a child’s biological sex or affirming a child’s belief that their gender identity is inconsistent with their biological sex (Tex. Health & Safety Code § 161.702).
The Supreme Court of Texas held that the law was constitutional in the case State v. Loe, 692 S.W.3d 215 (Tex. 2024).
Dr. Lau is affiliated with the University of Texas Southwestern Medical Center and holds privileges at Children’s Medical Center Dallas and Children’s Medical Center Plano. She was previously associated with the now-dissolved Gender Education and Care Interdisciplinary Support (GENECIS) Program, which focused on using medical interventions to transition minors' biological sex.
