At ENDO 2025, Dr. Monica Laronda (Lurie Children’s Hospital, Northwestern University) highlighted emerging research investigating how GLP-1 therapies and rising obesity rates may influence puberty onset, menarche timing, and sex-specific disease expression—particularly in adolescents with high BMI or genetic susceptibility. She also discussed environmental and epigenetic drivers of endocrine disruption and underscored the need to consider sex as a biological variable in metabolic research. Dr. Shellsea Portillo (St. Louis University Hospital) presented retrospective data indicating that GLP-1–associated weight loss significantly improved testosterone levels in obese men with type 2 diabetes, suggesting a possible avenue for further exploration as a non-hormonal strategy for managing obesity-related hypogonadism. Together, these insights underscore GLP-1’s emerging but preliminary role in reproductive and metabolic endocrine health.
