The Claim

Daily administration of liraglutide 3 mg for 32 weeks reduces the free androgen index by 28% in obese women with polycystic ovary syndrome compared to placebo, indicating a direct effect on hyperandrogenism independent of weight loss.

Source: Liraglutide 3 mg on weight, body composition, and hormonal and metabolic parameters in women with obesity and polycystic ovary syndrome: a randomized placebo-controlled-phase 3 study.

Cause and effect
1 study reviewed
In plain English

In obese women with polycystic ovary syndrome, taking liraglutide 3 mg daily for 32 weeks lowers the free androgen index by 28% compared to placebo, showing a direct reduction in androgen levels not caused by weight loss.

See the scientific wording

Liraglutide 3 mg administered daily for 32 weeks significantly reduces the free androgen index by 28% in obese women with polycystic ovary syndrome, compared to a slight increase in the placebo group, indicating a direct effect on hyperandrogenism independent of weight loss.

Why this might work

Liraglutide lowers insulin levels by making the pancreas release more insulin only when blood sugar is high and by reducing the liver's sugar production. Lower insulin means the ovaries make less male hormones, and the liver starts producing more of the protein that binds testosterone, making less of it free and active in the blood.

  1. Study: Liraglutide 3 mg on weight, body composition, and hormonal and metabolic parameters in women with obesity and polycystic ovary syndrome: a randomized placebo-controlled-phase 3 study.

    In a study, obese women with PCOS who took liraglutide for 32 weeks saw their male hormone levels drop by 28%, while those on a placebo saw a small rise — and this happened even after accounting for weight loss, meaning the drug directly helped lower harmful hormones.
