Purpose In this study, the partnership between sex hormone amounts and erection dysfunction (ED), and also the necessity of routinely measuring sex hormone amounts were evaluated. hormone amounts ( 0.05). Of the 100 sufferers, 18 (18%) acquired low tT, 77 (77%) had regular and 5 (5%) acquired high tT amounts. No statistically significant correlation was discovered between reduced libido and tT amounts ( 0.05). Twelve (66.6%) of the 18 sufferers with low tT had normal libido. Bottom line Analyzing the health background at length and performing an intensive physical evaluation can decrease the dependence on excessive research and consultations, and allows sufferers to save period and costs. for ED had been evaluated. MATERIALS AND Strategies In this research, we evaluated 100 consecutive sufferers admitted to an andrology clinic for ED. Inclusion requirements were: being 18 years outdated, having a clinically diagnosed ED for the prior six months as evaluated by our organization and having a normal sexual life with a female partner. Patients with a history of previous pelvic surgery, pelvic irradiation, chronic neurological disease, hypogonadism, or excess alcohol consumption, and also those who were on medication during the recruitment period were excluded from the study. All patients completed a detailed questionnaire, the validated Sexual Health Inventory for Men 5-item questionnaire, based on the International Index of Erectile Function questionnaire which covered all of the aspects of erectile dysfunction (IIEF-5).9,10 A physician examined all of the patients following the interview and requested the necessary tests be performed. Following 10 hours without food, triple blood samples for hormone analyses were taken at 15-minute intervals between 8.00 and 10.00 AM.11 Serum samples were kept at – 70 after a separation by centrifuge. Total testosterone (tT), free testosterone (fT), prolactin (PL), follicle stimulating hormone (FSH), and luteinizing hormone (LH) levels were studied with chemiluminescent immunoassay (ACS: 180-Chiron) and competitive radio immunoassay-(DSL) techniques. Measuring pituitary gonadotropins, FSH and LH can provide reliable clues to assist the physician in determining whether it is main or secondary hypogonadism. Based on the status of their libido, patients were divided into two groups as the normal libido group (n = 58) and the decreased libido group (n = 42). Libido groups were compared with age groups using chi-square assessments. In addition, again using the chi-square test, libido groups were compared with groups classified according to tT, fT and PL levels. An unpaired, two-sample t-test, one-way ANOVA, logistic regression analyses and Spearman and Pearson’s correlation analyses were used to compare the differences among the groups. RESULTS Mean age was 43 (23 – 80) years. The questionnaire required about 5 minutes to total. IIEF-5 score was less than 21 [9.8 4.3 (3 – 19)] in all study groups, which is indicative of ED. The IIEF-5 score was 17 to 21 in 6 of the 100 men (6%), suggesting moderate ED; 11 to 16 in 40 (40%), suggesting moderate to moderate ED; 8 to 10 in 18 (18%), suggesting moderate ED, and 7 or less in 36 (36%), suggesting severe ED. The mean tT, fT, PL, FSH and LH levels were 14.5 7.0 nmol/L (8.4 – 28.7 nmol/L, normal range), Fingolimod cost 72.5 46.5 pmol/L (30.1 – 189.8 pmol/L), 12.9 10.1 g/L (1.6 – 18 g/L), 8.4 10.9 IU/L ( 11 IU/L) and 6.2 6 IU/L (0.5 – 6 Fingolimod cost IU/L), respectively. There was a statistically significant correlation between Fingolimod cost tT and FSH and also between LH and FSH in Pearson (r = – 0.513, 0.001, respectively) and also in Spearman assessments (r = – Speer3 0.224, = 0.042 and r Fingolimod cost = – 0.459, 0.001, respectively). However, there was no correlation.
