Retrospective Analysis of Erectile Dysfunction (ED) Patients Based on a Large-scale Clinical Database

Sponsor: Second Affiliated Hospital, Zhejiang University, School of Medicine

Summary

The goal of this observational study is to analyze existing clinical data to characterize in male patients aged 18 and older diagnosed with Erectile Dysfunction (ED). The main questions it aims to answer are: What are the epidemiological features and comorbidity patterns (e.g., metabolic syndrome) in this patient population? How do sex hormone levels and penile hemodynamic parameters correlate with the severity of ED? Is there consistency between objective NPTR monitoring parameters and subjective patient-reported scores (IIEF-5, EHS)? This study does not have a comparison group or interventions. It is a retrospective analysis of existing data. Participants will not be asked to do anything new. The research involves analyzing their de-identified data that was previously collected during routine clinical visits, which includes: Demographic information, medical history, and lifestyle factors. Results from laboratory tests (e.g., blood biochemistry, sex hormones). Outcomes from diagnostic assessments (e.g., IIEF-5 questionnaires, CDDU, NPTR).
