Patients were prospectively registered to the study. Cases were divided into two groups as low and normal according to vit B12 levels. In the study, vit B12 levels \u2264200\u00a0mg\/dL were accepted as low. The Sexual Health Inventory for Men\u20105 (SHIM\u20105) was used to assess the erectile function. The SHIM\u20105 scores for the groups were compared. All patients with comorbid diseases, medication use, or previous surgical history predisposing toward ED and organic and\/or psychogenic causes for ED were excluded from the study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The study included 136 patients abiding by the study criteria among 957 patients.

The mean SHIM\u20105 value in the group was 15.48\u00a0\u00b1\u00a06.71. In the inadequate vit B12 and normal vit B12 groups, the mean SHIM\u20105 values were 15.30\u00a0\u00b1\u00a06.85 and 16.06\u00a0\u00b1\u00a06.28, respectively, with no significant difference between the two groups (<jats:italic>t<\/jats:italic>\u00a0=\u00a00.562, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.575).
