Analysis of the Male Sexual Dysfunction Related with Chronic Kidney Disease

Chronic kidney disease(CKD) and Sexual dysfunction are important public health problems in older man as a part of life. We investigated the relationship between two groups.

We examined sixty-five CKD patients on glomerular filtration rate (GFR), serum creatinine (sCr), Prevalence period and causative disease. Sexual function was evaluated by International Index of Erectile Function(IIEF-5), libido(2 items), ejaculation(4 items), frequency of sex in a month and serum testosterone. A control group composed of eighteen male adults who had visited to the general medical testing center in the hospital. They didn't have any combined disease and they were similar age range to the group of the CKD. We analyzed correlations between components of the CKD and sexual function.

The study revealed that all sexual components of the CKD group(mean age 51.8±2.6) were significantly worse than the control group; 12.3±3.9 of IIEF-5, 5.4±1.8 of libido and 10.1±2.2 of ejaculation, 1.4±0.7times of sex in a month in the CKD group and 18.3±3.5 of IIEF-5, 7.2±2.1 of libido and 15.3±2.9 of ejaculation, 2.9±1.1 times of sex in a month in the control group. The patients whose prevalence period of CKD was over than 3 years or whose sCr was over than 2.0ng/ml, had all sexual components worse significantly. Comparing by the causative disease of the CKD, there was no any significant difference. Analyzing by correlation, erectile function is related with serum glucose, sCr, Prevalence periods and libido is related with prevalence periods, and ejaculation is related with diabetes.

The patients with CKD may have a sexual dysfunction that make erection, libido and ejaculation and the number of their sex seemed to decrease. Therefore we need to have more attention to their sexual function as an important part of life.
