What does this score mean?
The Trust Index is not a treatment success rate; it is an editorial methodology score indicating to what extent the scientific finding evaluated on this page can be trusted. Study design, risk of bias, sample size, precision, direct applicability, reproducibility, transparency, and clinical relevance are evaluated together.
What did the study investigate?
It investigated the association of physical activity with female reproductive aging and the potential adiponectin mechanism.
How was it conducted?
Data from 152,435 individuals in the UK Biobank and 12,418 individuals in NHANES were analyzed; exercise, ovarian aging, and adiponectin signaling were experimentally evaluated in mice.
What was found?
An association between physical activity and menopausal status was found in humans; in mice, favorable changes in ovarian aging markers and the adiponectin pathway were found with exercise.
Limitations of the study
The human component is observational and does not demonstrate causality; a significant portion of the mechanistic findings comes from an animal model.
What does it mean clinically?
Although the general health benefits of exercise are strongly established, this study alone does not demonstrate that exercise delays menopause or reverses ovarian age.
What do we not know yet?
The causal effect of exercise dose on AMH/ovarian reserve and the actual timing of menopause in prospective human studies is not yet clear.

The study published in Nature Aging on August 14, 2026, reported a notable link between physical activity and female reproductive aging. Human data investigated the association, while mouse experiments investigated the potential adiponectin mechanism.
What was found in humans?
Researchers evaluated data from 152,435 individuals from the UK Biobank and 12,418 individuals from NHANES. Physical activity levels were lower in the postmenopausal group compared to the premenopausal group. However, this section is cross-sectional: It does not prove that exercise delays menopause; age, health status, and altered postmenopausal activity habits may influence the association.
What happened in the mouse experiments?
Physical activity better preserved the follicle reserve, delayed markers of ovarian aging, and increased adiponectin signaling in ovarian tissue. In mice with induced adiponectin deficiency, a significant portion of the protective effect of exercise was reduced. This finding suggests that adiponectin may be one of the contributing factors to the mechanism.
What is adiponectin?
Adiponectin is an adipokine associated with insulin sensitivity, fatty acid metabolism, inflammation, and mitochondrial metabolism. The new study indicates that this signaling pathway may also be linked to reproductive aging.
Why was AdipoRon investigated?
Researchers also tested the experimental agent AdipoRon, which activates adiponectin receptors, in mice. Favorable results were observed in markers of ovarian reserve preservation and reproductive lifespan. This is an entirely preclinical finding; AdipoRon is not an approved treatment for the purpose of delaying ovarian aging in women.
What does this mean for women today?
The benefits of exercise on cardiovascular health, muscle, bone, and insulin sensitivity are supported by robust human data. To state that it directly delays reproductive aging, prospective interventional studies are needed. It is premature to say “exercise definitely delays menopause”; the interpretation that “it may be associated with biological pathways that could influence ovarian aging” is more appropriate for the current data.
Frequently asked questions
Does exercise increase AMH?
This study did not show that exercise is a treatment that increases AMH in women.
Is intense exercise always beneficial?
No. Excessive energy deficit and intense exercise can lead to hypothalamic amenorrhea; exercise dose and energy balance are important.
