BACKGROUND AND OBJECTIVES: Vascular abnormalities are the most common factors in patients with erectile dysfunction (ED). There are limited number of case series investigating the etiology of corporoveno-occlusive dysfunction (CVOD). In this study, we evaluated ED patients with vascular etiologies and their serum biomarkers from a large database.
MATERIALS AND METHODS: The current study retrospectively examined the association between serum testosterone levels and basic lab works with Penile Doppler Ultrasonography (PDU) results. We retrieved and reviewed the records of 500 ED patients who had PDU at our institution between January 2012 and November 2018. One-way analysis of variance and Pearson's correlation coefficients were used to compare different parameters between groups (CVOD and penile arterial insufficiency) and between two quantitative variables, respectively.
RESULTS: Sixty patients who met the inclusion criteria were enrolled and examined in this study. Patients' mean age was 52.9 ± 11.5 years, and mean serum testosterone level was 15.57 ± 6.49 nmol/L. Thirty-nine (65%) out of 60 patients had abnormal EDV values (>5cm/sec), while eleven (18.3%) had abnormal PSV values (<35cm/sec). Among the patients with abnormal EDV values, we demonstrated that there was a statistically significant negative correlation between testosterone and CVOD (Pearson's; r = -0.283; p = .028).
CONCLUSIONS: Our findings supported that low serum testosterone level is a risk factor for CVOD and so for ED. Future studies would benefit from larger sample sizes in order to support or refute our findings.
