Among adults with type 2 diabetes (T2D), is the use of sodium-glucose cotransporter 2 inhibitors (SGLT2Is) associated with higher risk of male external genital infection (MEGI) than glucagon-like peptide-1 receptor agonists (GLP-1RAs)?In this cohort study with 239 757 participants, initiation of SGLT2Is was associated with a higher risk of MEGI compared with initiation of GLP-1RAs in patients with T2D. The increased risk of MEGI with the use of SGLT2Is was observed across different subgroup analyses.These findings suggest that patients with T2D newly receiving SGLT2Is are at a higher risk of MEGI compared with those receiving GLP-1RAs, and clinicians should be cautious when prescribing SGLT2Is to male patients with T2D.
