Serum Levels of 25-Hydroxy Vitamin D in Patients With Moderate and Severe Erectile Dysfunction

Study Overview
=================
Brief Summary
-----------------
In present study, we aimed to investigate the association between erectile function severity of serum 25-Hydroxyvitamin-D and cut-off level to treat men with erectile dysfunction.

Detailed Description
-----------------
Investigators retrospectively analysed 130 patients admitted to the complaint of erectile dysfunction between aged between 18-80 years old from June 2017 to October 2018 at Cigli Region Training Hospital Urology department and Recep Tayyip Erdogan University Urology Department. International index of erectile function-5 (IIEF-5) Turkish validated short form quesstionaire was performed to all patients. Antropometric characteristics including weight, height, waist circumference, body mass index (BMI) and presence of comorbide diseases were recorded. After detailed history and physical examination performed all patients, overnight fasting in the morning between 08:00-10:00, blood samples from antecubital vein were performed and serum glucose, lipid profile, follicular stimulating hormon (FSH), Luteinizing hormone (LH), total testosterone, prolactin, estradiol, 25(OH)D level were analysed. Presence of uncontrolled diabetes mellitus, uncontrolled hypertension, uncontrolled lipid metabolism disorders, neurological diseases, heamatological diseases, urinary tract infection, malignencies, chronic kidney failure, metabolic syndrome, psychiatric diseases and/or medical treatment, smoking, history of pelvic surgery, cardiac surgery and pelvic radiotherapy were accepted as exclusion criterias from the study. After IIEF-5 score adjust as 21 point, ROC analyse was used to calculate the cut-off value of 25(OH)D and level of 27.32 ng/mL was calculated as cut-off value. Patients were divided into two group according to 27.32 ng/mL level as a cut off value. Serum 25(OH)D level was lower than 27.32 ng/mL in group 1 (severe and moderate symptomatic group) and higher than 27.32 ng/mL in group 2 (mild symptomatic group).
