How to read this. Each line is one study, summarised in plain language from its PubMed abstract, with the authors' own sentence underneath on the study page. A count of studies is not a verdict: trials differ in size, length and quality, and a result in one group of women may not hold in another. Nothing here is medical advice.
Summaries are generated, then checked by machine against the abstract they came from; any summary that could not be matched word for word was left out. Our clinical lead is reviewing the summaries topic by topic, and this note will change when that is done. Corpus last refreshed 2026-11-03. Spotted a mistake? Tell us and we will fix the summary or remove the study.

- A meta-analysis of 18 randomized trials in healthy women found that physical activity programmes reduced circulating estradiol and testosterone levels, independent of menopausal status.
- A review of trials and cohort studies in pre and postmenopausal women found physical activity mostly decreased estrogens, progesterone and androgens, and increased sex hormone binding globulin, with small effect sizes.
- A review of 43 studies found diet and exercise interventions, especially combined with weight loss, better controlled estrogen levels linked to breast cancer risk in postmenopausal women.
- Sedentary overweight postmenopausal women did a year-long moderate-intensity physical activity program versus stretching, with limited evidence that sleep changes affected exercise-related weight, ghrelin or leptin changes.
