Not All Organs Age Alike: AI Unveils the Molecular Impact of Menopause (Nature Aging)

- 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.
