This single-center retrospective study analyzed the degree of association between urinary symptom improvement and erectile or ejaculatory function change in patients after prostatic artery embolization (PAE) for lower urinary tract symptoms secondary to benign prostatic hyperplasia. Urinary symptom severity (IPSS), erectile function (SHIM), and ejaculatory function (MSHQ-EjD) were assessed at baseline, 3 months, and 12 months after PAE. Among the 183 patients treated from 2014 to 2023, mean IPSS improved by 12.0 points. After adjustment for age, baseline score, medications, and vascular comorbidities, urinary-score change was associated with erectile-function-score change at the first (partial r = -0.17; P = .025) and second follow-up (partial r = -0.25; P = .020), strengthening in the baseline erectile-dysfunction subgroup (partial r = -0.38; P = .008). Strong urinary responders more often achieved the erectile-function minimal clinically important difference (26.3% vs 3.8%; P = .014). No significant association was found with ejaculatory function.
