Early Access to Testosterone Therapy in Transgender and Gender-Diverse Adults Seeking Masculinization: A Randomized Clinical Trial

Agents of scientific uncertainty: Conflicts over evidence and expertise in gender-affirming care bans for minors

Globally, as medical and mental health associations increasingly have expressed support for the gender-affirming care model for trans and gender expansive youth, this model has been paradoxically banned across the United States. Ban proponents have deemed the science behind gender-affirming care to be dangerously uncertain. Examining the first gender-affirming care ban for minors, Arkansas's Save Adolescents from Experimentation (SAFE) Act of 2021, we addressed the following two questions: 1) who are the scientists, clinicians, and political organizations that promote SAFE and similar bans?; and 2) what are the scientific arguments they make to defend SAFE in federal court? First, we developed a typology of the various "agents of scientific uncertainty" behind these bans, drawing on literature from the sociology and history of science and medicine as well as the political economy of scientific doubt. Second, we created and qualitatively analyzed a dataset featuring 375 unique citations referenced throughout federal litigation over SAFE to identify these agents of scientific uncertainty's arguments. We sorted these arguments into eight categories, which reveal how agents distorted scientific evidence and exaggerated real uncertainties and risks in gender-affirming care. This case study establishes a frame for understanding the growing prevalence and legal impact of scientific arguments against gender-affirming care.

Limitations and Future Directions in Sex, Sexuality, and Gender Diverse Research in Neurology

Sex, sexuality, and gender diversity is understudied and underserved in neurology. Neurology research inclusive of LGBTQIA+ (lesbian, gay, bisexual, transgender, queer, intersex, asexual) people is limited. Existing research struggles with a paucity of neurology studies collecting sex, sexuality, and gender diverse (SSGD) data, conflation of sex and gender, lack of precision in measures, neglect of younger and older populations, nebulous benefit to community, and absent intersectionality. Future directions in SSGD neurology research include precise and community-based measurements, respect for LGBTQIA+ colleagues, and the application of minority stress models. All patients stand to benefit from research that elucidates how SSGD variables influence neurological health. ANN NEUROL 2024;95:421-431.
