Texas Attorney General Ken Paxton has filed a lawsuit against a Dallas-area physician, alleging that she illegally provided gender transition treatments to 21 minors in violation of state law.
The lawsuit claims that Dr. May C. Lau prescribed high-dose cross-sex hormones to minors for the purpose of transitioning their biological sex or affirming a gender identity inconsistent with their biological sex.
“Texas passed a law to protect children from these dangerous unscientific medical interventions that have irreversible and damaging effects,” Paxton said in a press release on Thursday. “Doctors who continue to provide these harmful ‘gender transition’ drugs and treatments will be prosecuted to the full extent of the law.”
Senate Bill 14, which took effect in September 2023 and was upheld by the Texas Supreme Court in June, prohibits gender transition medical interventions such as surgeries, puberty blockers, and cross-sex hormones for minors.
The law also mandates that the Texas Medical Board shall revoke the medical license or other authorization to practice medicine of a physician who violates its provisions.
“The debate in Texas on the legality of dangerous and experimental medical procedures seeking to transition or affirm a child’s belief that their gender identity is inconsistent with their biological sex is over,” attorneys wrote in the filing.
The attorney general’s office said that the action against Lau represents the beginning of enforcement under SB14 “against those who have violated the law by providing, prescribing, administering, or dispensing cross-sex hormones to minors for the purposes of transitioning their biological sex.”
According to the suit, evidence obtained by the attorney general’s office indicates that Lau provided high-dose testosterone—a controlled substance—to biological female minors.
The treatments were allegedly prescribed to transition the minors’ biological sex or affirm a gender identity different than their biological sex.
The lawsuit further alleges that Lau used false diagnoses and billing codes to mask the unlawful prescriptions, “misleading pharmacies, insurance providers, and/or patients.”
Lau is an employee of the University of Texas Southwestern Medical Center and serves as the Medical Director of the Adolescent and Young Adult Clinic at Children’s Medical Center Dallas, according to the suit. She has published extensively on topics related to adolescent health, including gender dysphoria.
The lawsuit seeks temporary and permanent injunctions to prevent Lau from prescribing supraphysiologic doses—doses greater than that normally found in the human body—of testosterone and estrogen to minors for the purpose of gender transitioning. It also accuses her of engaging in deceptive trade practices under the Texas Business and Commerce Code.
Lau did not respond to a request for comment from The Epoch Times by publication time.
