A Larger Biological Map of Menopause

Researchers at the Barcelona Supercomputing Center have produced what they describe as the first large-scale atlas of female reproductive system aging, offering a more detailed picture of how menopause affects the body beyond the ovaries alone. Published in Nature Aging, the study combines tissue imaging, gene-expression analysis, deep learning, and high-performance computing to reconstruct aging trajectories across seven reproductive organs.

The work addresses a longstanding gap in biomedical research. Menopause affects a large and growing share of the global population, yet its biology has often been studied through a narrow lens. The new atlas instead treats menopause as a system-wide transition with organ-specific consequences, helping explain why its effects are tied to cardiovascular, metabolic, neurodegenerative, and bone-related risks as well as reproductive change.

What the Dataset Shows

The team integrated 1,112 tissue images from 659 samples taken from 304 women between the ages of 20 and 70. Using AI-based image classification and the MareNostrum 5 supercomputer, the researchers analyzed visible tissue changes alongside the activity of thousands of genes. The result is a layered map of how aging unfolds in the uterus, ovary, vagina, cervix, breast, and Fallopian tubes.

The central finding is that reproductive aging is neither uniform nor linear. Some organs begin changing gradually years before menopause, while others shift far more abruptly around the transition itself. The ovary and vagina showed progressive aging patterns, whereas the uterus underwent sharper changes around menopause. Even within a single organ, tissues behaved differently. In the uterus, for example, the mucosa and muscle did not age in lockstep.
