LL-PE: lifelong premature ejaculation. CTRL: controls. SBP: systolic blood pressure. DBP: diastolic blood pressure. BMI: body mass index. AI: augmentation index. AI@75: augmentation index corrected by heart rate. PEDT: premature ejaculation diagnostic tool. IELT: intravaginal ejaculatory latency time. TSH: thyroid stimulating hormone. *𝑃<0.05; **𝑃<0.01; ***𝑃<0.001.
