PREPARED FOR NATIONAL EDUCATION ASSOCIATION
My name is Dr. Michelle Cretella, M.D., Executive Director of the American College of Pediatricians (ACPeds), a national organization of pediatricians and other health professionals that promotes the well-being of children and upholds the ethical principles of the Hippocratic Oath. Educators must be aware that transgender affirmative intervention, consisting of social transition, pubertal blockade, cross-sex hormones and cross-sex surgery, is not the international standard of care for youth with transgender belief or a diagnosis of gender dysphoria.
Many medical organizations around the world, including the Australian College of Physicians, the Royal College of General Practitioners in the United Kingdom, and the Swedish National Council for Medical Ethics have characterized prescribing puberty blockers and cross-sex hormones in youth as experimental and dangerous. World-renowned child psychiatrist Dr. Christopher Gillberg has referred to this as “possibly one of the greatest scandals in medical history.”  His neuropsychiatry research group at Gothenburg University has called for “an immediate moratorium on the use of puberty blocker drugs because of their unknown long-term effects.” 
The United Kingdom, Sweden and Finland have taken steps to limit these interventions in youth. In December of 2020, the High Court of the United Kingdom ruled in the case of Keira Bell which barred hormonal interventions in youth under the age of 16, and decreed physicians seek court approval for hormonal interventions in youth between 16 and 18 years of age. Sweden’s Karolinska University Hospital similarly restricted its use of the Dutch Protocol to children over 16 years of age stating it is “potentially fraught with extensive and irreversible adverse consequences such as cardiovascular disease, osteoporosis, infertility, increased cancer risk, and thrombosis.” Finland, too has issued guidelines restricting these interventions.
The vast majority of young children with gender incongruence will outgrow it when supported through natural puberty. Blocking puberty robs these children of the natural developmental period necessary for most to come to accept their bodies. Most gender-distressed teens are ordinary girls and boys who are anxious, depressed, traumatized, and uncomfortable with their bodies and struggling with their identity. Several studies show that teens can embrace their bodies through counseling alone without high-risk sterilizing chemical or surgical interventions.
Puberty is not a disease. It is a critical window of normal development that is irreparably disrupted by puberty blockers. There are no long-term studies of Lupron or other puberty blockers for gender incongruence. Consequently, there is no evidence that puberty blockers are reversible and harmless in gender incongruent youth as is claimed. To the contrary, when normal puberty is artificially arrested, valuable time is forever stolen from these children, time that should be spent in normal development. This time period, during which highly significant and irreplaceable advances in bone, brain, and sexual development occur, is time – and development – that can never be given back.
Puberty blockers also have very harmful side effects listed in Lupron’s package insert. All puberty blockers, including Lupron, arrest sexual development by acting on the brain. Boys are chemically castrated and girls chemically driven into premature menopause for as long as the puberty blockers are used. This developmental arrest may result in permanent sexual dysfunction, infertility,  bone loss, and altered brain development. In one report, gender-distressed girls exhibited more self-harm and emotional problems, and greater body dissatisfaction while taking puberty blockers.
Prior to implementation of the Dutch Protocol, the majority of gender-distressed children would embrace their bodies when supported through natural puberty. In contrast, all studies of gender-dysphoric youth given puberty blockers reveal nearly 100% of them go on to identify as ‘transgender’ and request cross-sex hormones. This suggests that puberty blockers “lock” kids into their gender confusion. As a result, these children who have their development blocked in early puberty, and are later given cross-sex hormones, may be permanently sterilized rather than spontaneously healed. Cross-sex hormones also put youth at an increased risk of heart attacks, stroke, diabetes, blood clots, cancer and more across their lifespan. The best long-term evidence we have among adults shows medical intervention fails to reduce suicide.
Sadly, many minors and their parents, as well as educators, and many others are being led astray by a vocal sector of the medical establishment driven by a dangerous ideology and economic opportunism, rather than by science and sound medical ethics.
