Postmenopausal ovaries kept changing from age 50 to 75

What the research found
On 14 October 2026 Northwestern University and the Buck Institute described an Aging Cell proteomics study of ovaries from 28 postmenopausal women ages 50 to 75. Across 5,812 protein groups, ovaries from women in their 50s had more proteins tied to maintaining tissue structure, while older ovaries had more proteins tied to inflammation, immune activity, and tissue remodeling. The largest contrasts were between the 50s and age 70 and older. Some proteins previously linked to ovarian cancer were more abundant in aging ovaries, with the strongest signal in the 60s, but every sample looked normal and cancer-free. The authors say the data do not answer whether a healthy ovary should be removed. This is an observational tissue study, not a screening test. Not medical advice.
Evidence level: Human study. A study in people, but an association isn't proof of cause.
