STUDY PROTOCOL: CROSS-CULTURAL VALIDATION, DIAGNOSTIC ACCURACY, AND SURGICAL RESPONSIVENESS OF THE UZBEK IIEF-5 A MULTICENTER NATIONAL COHORT INCLUDING SINGLE-COMPONENT PENILE PROSTHESIS RECIPIENTS

Abstract

Erectile dysfunction (ED) is a common male sexual health disorder associated with cardiometabolic disease, psychological distress, and impaired quality of life. Standardized patient-reported outcome measures (PROMs) are essential for ED detection, severity grading, and monitoring treatment response, yet measurement equivalence requires rigorous cross-cultural adaptation and psychometric validation.
