Female reproductive organs showed different aging patterns
An observational analysis of 1,112 tissue images and 659 samples from donors aged 20–70 found gradual ovarian changes but an abrupt uterine shift around menopause.
659 participants
Limit: The donor count is missing, limiting assessment of the independent sample size

In human donors aged 20–70, an observational study compared aging patterns across seven female reproductive organs. The researchers used artificial intelligence to analyze 1,112 microscope images of tissue and examined gene activity in 659 samples.
The ovary showed gradual age-related changes. The uterus showed an abrupt shift in molecular features and tissue structure around menopause. An independent analysis of proteins in blood plasma from a large population cohort supported this uterine transition. Within the uterus, the muscle layer showed strong age-related changes involving remodeling of the material surrounding cells and immune activation. The vaginal lining also showed a sharp transition around menopause.
Why it matters
Female reproductive aging has implications for health throughout the body. The authors present their tissue-level map as a framework for studying late-life health.
Caveats
This observational analysis cannot establish that menopause caused the tissue changes. The abstract reports image and sample counts, but not the number of donors.
