Abstract
Objective: To investigate the impact of age, various hormonal levels, and biochemical markers on penile cavernous body vascular function in patients with erectile dysfunction (ED). Me-thods: A retrospective analysis of clinical data from male patients with ED who underwent color duplex Doppler ultrasonography (CDDU) and intracavernosal injection test (ICI) at the Reproductive Medicine Center of Peking University Third Hospital from January 2020 to August 2023. Data were managed and processed using SPSS 29.0, and a multivariable Logistic regression analysis was conducted.
Results: A total of 700 ED patients were included, with 380 showing negative ICI results and 320 positive. In the study, 84 patients had a peak systolic velocity (PSV) < 25 cm/s, while 616 had PSV≥25 cm/s; 202 patients had end-diastolic velocity (EDV)>5 cm/s, and 498 had EDV≤5 cm/s. 264 patients had abnormal PSV and/or EDV results, and 436 had normal results for both. Patients with vascular ED had significantly lower estrogen levels (t=-3.546, P < 0.001), lower testosterone levels (t=-2.089, P=0.037), and a higher rate of hyperglycemia (χ2=12.772, P=0.002) compared with those with non-vascular ED. The patients with arterial ED were older (t=3.953, P < 0.001), had a higher rate of hyperglycemia (χ2=9.518, P=0.009), and a higher estrogen/testosterone ratio (t=2.330, P=0.020) compared with those with non-arterial ED. The patients with mixed arteriovenous ED had higher age (t=3.567, P < 0.001), lower testosterone levels (t=-2.288, P=0.022), a higher rate of hyperglycemia (χ2=12.877, P=0.002), and a larger estrogen/testosterone ratio (t=2.096, P=0.037) compared with those with normal findings. Multifactorial Logistic regression analysis indicated that higher levels of estrogen were a protective factor for vascular ED (OR=1.009, 95%CI: 1.004-1.014), and glucose≥7.0 mmol/L was a risk factor (OR=0.381, 95%CI: 0.219-0.661). Older age was a risk factor for arterial ED (OR=0.960, 95%CI: 0.938-0.982). Additionally, older age (OR=0.976, 95%CI: 0.958-0.993) and glucose levels of 5.6-6.9 mmol/L (OR=0.591, 95%CI: 0.399-0.876) were also risk factors for mixed arterio-venous ED.
Conclusion: Hyperglycemia and aging may impair penile cavernous body vascular function, while higher levels of estrogen may have a protective effect on it.
