Glucagon-like receptor-1 agonists and impotence: A meta-analysis.

Abstract

Background: Glucagon-like peptide receptors-1 agonists (GLP-1 agonists) have revolutionized the treatment of obesity and diabetes due to their potent effects on weight and glycemic control, and cardiorenal protection. However, emerging reports and post-marketing surveillance have raised concerns regarding erectile dysfunction (ED) or impotence in a subset of male patients.

Aim: To assess the association between GLP-1 agonists, ED, total (TT) and free testosterone (FT), sex hormone binding globulins (SHBG), luteinizing hormone (LH), and follicular stimulating hormone (FSH).

Methods: We systematically searched PubMed, Google Scholar, and Web of Science in November and December 2026 for articles examining the association between GLP-1 agonists and ED, with no publication date restriction. However, only articles published in the English language were eligible. The terms used were GLP-1 agonists, ED, semaglutide, liraglutide, ozympic, tirzepatide, dulaglutide, and Impotence.

Results: One hundred seventy-two articles were found; after removing duplicates, 63 remained, of which 12 full texts were screened, and 7 studies were included in the final meta-analysis. Seven studies involving 237 males were included. GLP-1 agonist therapy improved ED score with a significant statistical difference, MD = 2.73, 95% confidence interval (CI): 1.64-3.83. A significant increase was found regarding TT, SHBG, and FSH, MD 73.04, 95%CI: 16.91-129.17, MD 7.00, 95%CI: 1.71-12.30, and MD 0.46, 95%CI: 0.01-0.91 respectively.

Conclusion: No significant differences were evident regarding the FT, and LH. GLP-1 agonists significantly improved ED, TT, SHBG, and FSH in males, no effects were observed on FT, and LH; larger randomized trials are needed.
