Abstract
The purpose of this study was to compare the serum Folic Acid (FA) levels in patients with Erectile Dysfunction (ED) and healthy controls and whether levels vary with its severity.The study was carried out on 77 sexually active individuals, out of which 41 complained of ED and 36 were apparently normal.Patients were excluded if they hadany diseasesknown to cause ED.The severity was further categorised based on IIEF-5 scores. Blood serum levels of testosterone, lipid profile, random blood sugar, liver function test, renal function test and FA levels were obtained in each patient. Independent-samples t test of significance was used when comparing between two means. Pearson's correlation coefficient (r) test was used for correlating data. All clinical and biochemical parameters except FA were comparable in both the groups. FA levels were significantly decreased in ED group (5.29 vs. 10.8; p value=.004). Smoking habits were comparable between the groups, and FA levels did not vary among smokers and nonsmokers (p value=.46). Serum FA levels significantly declined with increasing severity of ED (8.28 vs. 5.56 vs. 4.37 vs. 3.5; p value<.001). Thus, decreased FA might possibly be one of the novel risk factors for ED.
