Yoga studies leave several hormone effects in PCOS uncertain
The review found uncertain changes in several hormones. Fasting glucose estimates both favored lower levels, but their uncertainty differed.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
The reported estimates left yoga's effects on anti-Müllerian hormone and testosterone uncertain. A decrease in luteinizing hormone was reported, while follicle-stimulating hormone remained uncertain. Both fasting glucose estimates pointed toward lower levels, but one study's uncertainty range also allowed no difference. These laboratory findings do not establish benefits for PCOS symptoms, fertility or longer-term health.
This abstract-based summary lacks comparison conditions and intervention lengths. Risk of bias varied, and some publications described the same trial.
Why results were summarized separately
Of 5 publications, 3 reported on the same trial; counting participants once gave 258 women. Separately, the authors did not pool results because study numbers were limited and the data differed across studies.
Reading uncertain hormone results
The uncertainty ranges for anti-Müllerian hormone and testosterone included both a decrease and an increase. That leaves the direction of any effect unresolved; it does not establish equivalence between yoga and the study comparison conditions.
