The Cass Review [was] an independent assessment of gender treatment for youths. The four-year review of research, led by Dr. Hilary Cass ... found no definitive proof that gender dysphoria in children or teenagers was resolved or alleviated by what advocates call gender-affirming care, in which a young person's declared "gender identity" is affirmed and supported with social transition, puberty blockers and/or cross-sex hormones. Why would our government and medical institutions continue to frame gender-affirming care as medically necessary [despite] the risks and irreversible consequences of gender interventions for youths, including bone density loss, possible infertility, the inability to achieve orgasm and the loss of functional body tissue and organs? In Britain, a lawsuit by a gay girl named Keira Bell against Britain's leading gender clinic instigated the investigation that led to the Cass Review. "I'm already hearing from the boards of directors and trustees of some hospital systems who are starting to get nervous about what they've permitted," [said] Erica Anderson, a former president of the U.S. Professional Association for Transgender Health and a transgender woman. In recent years, a number of detransitioners in the United States have brought suit charging malpractice or the failure to provide informed consent. If American doctors admit their approach was wrong, it's going to be a costly and politically explosive practice to undo.
