Prevalence rates of PE syndromes were 35.66% for LPE, 28.07% for APE, 12.73% for NVPE, and 23.54% for PLED. Patients with APE had the highest mean ages and BMI scores, and they more frequently reported several comorbidities, including sexual desire disorder, hypertension, diabetes mellitus, chronic prostatitis, and erectile dysfunction.
