• Not all organs age uniformly or linearly: the ovary and vagina show progressive aging beginning years before menopause, while the uterus undergoes much more abrupt changes around the menopausal transition (BSC-CNS, Nature Aging 2026).
• Tissues within the same organ also age at different rates – e.g., the uterine mucosa vs uterine muscle – with menopause acting as a 'turning point' that profoundly reorganizes other organs and tissues of the reproductive system (Marta Melé, study director).
• The atlas integrated 1,112 tissue images from 659 samples from 304 women aged 20-70, analyzing the expression of thousands of genes across seven reproductive organs: uterus, ovary, vagina, cervix, breast, and Fallopian tubes.
• Molecular aging signals were also detectable in blood plasma from 21,441 women, opening a path to non-invasive monitoring of reproductive-organ aging.
• The paper is 'Multimodal data analysis reveals asynchronous aging dynamics across female reproductive organs,' Nature Aging (2026); bioRxiv preprint DOI 10.1101/2025.05.16.654406.
