Mortality and morbidity from cardiovascular disease differ between men and women, and sex differences in lipid profiles may contribute to this difference. Starting at puberty, male individuals have more atherogenic cholesterol profiles, including lower high-density lipoprotein cholesterol (HDL-C) levels, than female individuals.1 The degree to which sex hormones vs sex chromosomes and other factors contribute to this difference is unknown. The gender-affirming treatment of transgender and gender-diverse youth provides a unique opportunity to study the association of sex steroids with cholesterol in different sex-chromosome contexts.
