This study aimed to assess the angiographic correlation between coronary artery stenosis and internal iliac-internal pudendal artery (II-IPA) stenosis and evaluate its association with erectile dysfunction (ED). We reviewed the data of 91 patients who had undergone pelvic angiography (PA) to evaluate II-IPA stenosis and coronary angiography (CAG) due to suspected coronary artery disease. Erectile function (EF) was evaluated using the International Index of Erectile Function before CAG and PA. CAG was performed first, followed by PA of the bilateral II-IPA. Regardless of the location and number of stenosis sites, based on CAG, we categorized the patients into two groups. Patients with a maximum stenosis <50% and ≥50% on CAG were assigned to Group I and Group II, respectively. Then, the EF domain score and the diameter stenosis (DS) of II-IPA were evaluated and compared. Overall, 55 patients comprised Group I, while 36 patients comprised Group II. ED was present in 96.3% and 97.2% of the patients in Group I and II, respectively. There was no statistical difference between the groups in the severity of ED (p = 0.457). PA revealed that 14.5% and 36.1% of patients in Groups I and II had ≥50% stenosis of the II-IPA. The mean DS of II-IPA in Group II was greater than that in Group I (p = 0.017). There was a statistically significant correlation between the degree of coronary artery stenosis and the degree of II-IPA stenosis (r = 0.295, p = 0.005). This study revealed that coronary artery stenosis correlates with II-IPA stenosis. The presence and degree of coronary artery stenosis or II-IPA stenosis indicate the necessity for more active treatment in patients with ED.
