SEX HORMONES AND ERECTILE DYSFUNCTION IN HEMODIALYSIS PATIENTS

Objective: To determine the prevalence of Erectile Dysfunction (ED) in hemodialysis patients (HD) and to study the associated changes in sex hormones in these patients. Methodology: This is a hospital based cross sectional study conducted at hemodialysis units of Shalamar and Mayo Hospitals, Lahore from January to March 2008. All male patients with ESRD on maintenance (HD), whose spouses were alive and able to perform intercourse, were included in the study. Patients with cognitive and communication deficits were excluded from study. International index of erectile function-5(IIEF-5), adopted in Urdu was used for determination of prevalence of ED. Demographic data was collected and sex hormones {total testosterone, Dihydroepiandrosteronediones (DHEA), Follicle Stimulating Hormone (FSH), Leutinizing Hormone (LH) and serum Prolactin} were measured. Results: A total number of fifty patients were included in the study. The major cause of ESRD was diabetes mellitus 28 (56%). The prevalence of ED was 86% with a mean IIEF-5 score 10.36 + 7.13. The majority of patients, 33 (66%), were suffering from a severe degree of ED. The total testosterone level was low in 30 (60%) patients and DHEA were low normal in most of patients, 46 (92%). Compared to patients with non-ED, those with ED had a significantly lower DHEA (1.93 ± 0.73 vs 0.81 ± 0.11, p value = 0.007). Total testosterone and DHEA had a negative correlation with age and diabetes mellitus. FSH showed a variable response in these patients, it was low ( 9.74 mIU/ ml) in eight patients. LH was low ( 7.8 mIU/ml) in fifteen patients. FSH and LH showed a positive correlation with duration of dialysis. Prolactin level was low in 21(42%) patients. Total testosterone, FSH, LH and Prolactin had no association with ED. Conclusion: The majority of the patients suffering from ESRD, on maintenance HD had ED. DHEA was significantly lower in patients with ED, compared to those with no-ED. Total testosterone and DHEA had an inverse relationship with diabetes and age of the patients. Total testosterone, FSH, LH and prolactin did not affect erectile function.
