The Myth of "Reliable Research" in Pediatric Gender Medicine: A critical evaluation of the Dutch Studies-and research that has followed.

Two Dutch studies formed the foundation and the best available evidence for the practice of youth medical gender transition. We demonstrate that this work is methodologically flawed and should have never been used in medical settings as justification to scale this "innovative clinical practice." Three methodological biases undermine the research: (1) subject selection assured that only the most successful cases were included in the results; (2) the finding that "resolution of gender dysphoria" was due to the reversal of the questionnaire employed; (3) concomitant psychotherapy made it impossible to separate the effects of this intervention from those of hormones and surgery. We discuss the significant risk of harm that the Dutch research exposed, as well as the lack of applicability of the Dutch protocol to the currently escalating incidence of adolescent-onset, non-binary, psychiatrically challenged youth, who are preponderantly natal females. "Spin" problems-the tendency to present weak or negative results as certain and positive-continue to plague reports that originate from clinics that are actively administering hormonal and surgical interventions to youth. It is time for gender medicine to pay attention to the published objective systematic reviews and to the outcome uncertainties and definable potential harms to these vulnerable youth.

Reconsidering Informed Consent for Trans-Identified Children, Adolescents, and Young Adults.

In less than a decade, the western world has witnessed an unprecedented rise in the numbers of children and adolescents seeking gender transition. Despite the precedent of years of gender-affirmative care, the social, medical and surgical interventions are still based on very low-quality evidence. The many risks of these interventions, including medicalizing a temporary adolescent identity, have come into a clearer focus through an awareness of detransitioners. The risks of gender-affirmative care are ethically managed through a properly conducted informed consent process. Its elements-deliberate sharing of the hoped-for benefits, known risks and long-term outcomes, and alternative treatments-must be delivered in a manner that promotes comprehension. The process is limited by: erroneous professional assumptions; poor quality of the initial evaluations; and inaccurate and incomplete information shared with patients and their parents. We discuss data on suicide and present the limitations of the Dutch studies that have been the basis for interventions. Beliefs about gender-affirmative care need to be separated from the established facts. A proper informed consent process can both prepare parents and patients for the difficult choices that they must make and can ease professionals' ethical tensions. Even when properly accomplished, however, some clinical circumstances exist that remain quite uncertain.
