Blood test may reveal hidden clues about erectile dysfunction
NCT ID NCT07274982
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether a score called Modified EASIX, calculated from routine blood tests, can help predict how severe erectile dysfunction (ED) is. Researchers reviewed medical records of 380 men aged 18-65 and compared the score between those with and without ED. No treatments or extra tests were given—just analysis of existing data.

Who is studied
Adult male patients aged 18-65 who attended the urology outpatient clinic and had documented IIEF-5 scores and routine laboratory results (LDH, CRP, platelet count) between January 2024 and September 2025. The study includes both patients with erectile dysfunction (IIEF-5 ≤ 21) and those without erectile dysfunction (IIEF-5 ≥ 22), using retrospectively collected medical records from a single center (Defne State Hospital).
