Does Metformin Affect Sexual Performance in Men?
Metformin does not directly impair sexual performance in men. Research shows metformin may actually improve sexual function by addressing underlying insulin resistance and reducing inflammation. A 2018 study found that men with diabetes who took metformin experienced improved erectile function scores compared to those on other medications. The drug's ability to enhance blood sugar control and vascular health can support better circulation, which is crucial for sexual performance. However, some men may experience gastrointestinal side effects that could indirectly affect libido or comfort during intimacy. If you're experiencing sexual dysfunction while taking metformin, consult your healthcare provider to evaluate other potential causes and treatment options.
