Georgia’s Republican Gov. Brian Kemp on Thursday signed a ban on guideline-directed gender-affirming healthcare for transgender and nonbinary youth that was passed earlier this week by the GOP-controlled state legislature.

The law threatens to revoke the medical licenses of physicians who administer treatments for gender dysphoria in minor patients that are overwhelmingly considered safe, effective, and medically necessary by every scientific and medical society with relevant clinical expertise.

A previous version of Senate Bill 140 applied exclusively to surgical interventions, but the version signed into law Thursday also prohibits hormone replacement therapies, although treatment with puberty blockers is still allowed.

The move by GOP legislators to expand the healthcare interventions covered by the legislation follows pressure from conservatives like far-right U.S. Rep. Marjorie Taylor Greene, who represents Georgia’s 14th Congressional District in the House and urged the state’s lawmakers last week to make the bill more restrictive.

At the time, Greene also objected to the draft bill’s “limited exceptions” carved out for cases where patients are treated for conditions other than gender dysphoria, including those diagnosed with “a medically verifiable disorder of sex development,” provided the physician can attest they are medically necessary.

These provisions were kept intact in the bill’s final iteration, which contains additional exceptions for the treatment of partial androgen insensitivity syndrome and in circumstances where the minor patient was being treated with hormone replacement therapies prior to July 1, 2023.

A chorus of objections to and condemnations of the legislation have come from LGBTQ groups, along with legal and civil rights advocacy organizations and medical societies, clinicians, and scientists, including the Georgia Psychological Association.

The Human Rights Campaign, America’s largest LGBTQ advocacy group, issued a statement shortly after Kemp signed the bill Thursday, declaring that Georgia had become “the largest state to legislatively enact such a discriminatory ban.”

“Governor Kemp should be ashamed of himself — taking life-saving care away from vulnerable youth is a disgusting and indefensible act,” Human Rights Campaign State Legislative Director and Senior Counsel Cathryn Oakley said in the statement. “This law harms transgender youth and terrorizes their families, but helps no one.”

Despite the wave of legislation across the country barring access to or criminalizing gender affirming care, in most cases for minor patients, the group noted in Thursday’s release that “polling by Patinkin Research Strategies released this month shows that only 26 percent of likely November 2024 voters in Georgia supported the legislation, while 66 percent opposed it” including 63 percent of independent and 59 percent of likely Republican voters.

According to the findings of a Human Rights Campaign study that were announced Wednesday, “more than half (50.4 percent) of trans youth (ages 13-17) have lost or are at risk of losing access to age appropriate, medically necessary gender-affirming care in their state” – care, the group stressed, that “can be lifesaving.”

Following the Georgia legislature’s passage of the SB 140 earlier this week, the ACLU warned it would “[interfere] with the rights of Georgia parents to get life-saving medical treatment for their children” and prevent “physicians from properly caring for their patients.”

The Southern Poverty Law Center released a statement by Beth Littrell, the organization’s senior supervising attorney for its LGBTQ and Special Litigation Practice Group, calling the bill a “cynical partisan attack on transgender youth, medical autonomy, and parental rights” and urging Kemp to “leave personal healthcare decisions in the capable hands of parents, children, and their doctors.”
