Introduction: Many studies suggest that varicoceles are associated with hypogonadism and varicocele repair can increase testosterone levels and improve erectile function.Aim: The aim of this retrospective study was to analyze the impact of varicocele and varicocele surgery on testosterone level, semen quality, and erectile function.Methods: Our study included 265 infertile males with a clinical varicocele. This group was divided into three groups: group 1 (193) patients who did not receive surgery, group 2 (72 patients) who were operated on according to the Palomo procedure and group 3 (28 patients), who acted as a control group without a varicocele. All patients completed the International Index of Erectile Function IIEF-5 (German version) and underwent semen analysis. Serum testosterone, follicle stimulating hormone (FSH), and luteinizing hormone (LH) were measured at inclusion into the study and after surgery.Main outcome measures: Changes in semen quality, erectile function, and serum hormones after surgery.Results: The IIEF-5 scores in groups 1 and 2 were 21.01 ± 2.2; and 21.74 ± 1 respectively, and the resulting t-test for equality of variance was significant (p < 0.0001). Total testosterone level in groups 1 and 2 were 3.16 ± 0.37 and 3 ± 0.01, respectively, and the resulting t-test for equality of variance was significant (p < 0.0001). The results of the semen analysis were better in group 2 (after surgery) (28.6%, p < 0.001) in comparison to group 1. Interestingly, pre-operative serum testosterone levels were lower in patients with later improvement of semen analysis (p = 0.05). Body mass index (p = 0.8), pre-operative serum FSH (p = 0.9), LH (p = 0.2), and nicotine consumption (p = 0.6) were similar in both the group that saw improvement and the group with no change in semen quality.Conclusion: Semen quality improved in 28.6% of patients after varicocele surgery. Erectile dysfunction (ED) improved after varicocele surgery. We report that lower pre-operative serum testosterone level might be a possible indicator for successful surgical outcome.

e17545 Background: Androgen receptor-targeted agents Abiraterone and Enzalutamide (Abi/Ez) prolonged overall survival in metastatic castration resistant prostate cancer (mCRPC). Patients with very-low serum testosterone levels seem to have less benefit from these therapies as well as more aggressive prostate cancer. Methods: A retrospective observational cohort study was conducted to evaluate whether a serum testosterone measured at time of start first-line therapy with Abi/Ez is related to overall survival (OS) and time-to-treatment failure (TTF) in mCRPC patients. Kaplan-Meier survival estimates and Cox-regression models were used for time-to-event analyses. The best cut-off for testosterone was defined using Log-rank statistics (Lausen and Schumacher). X² test and Mann-Whitney U-test were applied to compare categorical and continuous variables, respectively. Logistic regression was used to assess characteristics related to serum testosterone levels. Statistical significance was fixed at 0.05. Results: From May 2012 to February 2017, 100 patients were assessed. Median follow-up was 27.8 months (range 2.23 to 68.26). Pts with a high testosterone level ( > 28.2; n = 20) achieved a significantly higher OS (median 66.0 vs 31.9 mo, testosterone > 28.2 HR: 0.206, 95% CI 0.074 to 0.571, p = 0.002) and TTF (median 30.6 vs 11.8 mo, testosterone > 28.2 HR: 0.408, 95%CI 0.219 to 0.762, p = 0.005) than pts with a low serum testosterone level ( < 28.2; n = 80), regardless of receiving therapy with either Abi (n = 69) or Ez (n = 31). Pts with a higher testosterone level were younger (median 67.7 vs 73.6 years; p = 0.026), had a higher body mass index (BMI) (28.5 vs 25.9, p = 0.023) and a lower PSA at start Abi/Ez (12 vs 26, p = 0.031) than pts with lower values. Age (OR 0.93, 95%CI 0.8 to 0.9, p = 0.021), BMI (OR 1.21, 95%CI 1.1 to 1.4, p = 0.006) and baseline PSA (OR 1.2, 95%CI 1.03 to 1.4, p = 0.020) were significantly associated with testosterone > 28.2. After 4 months of Abi/Ez treatment, PSA decrease > 50% of baseline was seen more frequently in high testosterone levels group than in low testosterone levels pts (90% vs 57.5% of pts, respectively, p = 0.007). Conclusions: Pts with high levels of testosterone ( > 28.2) achieved a better OS and TTF when treated with Abi/Ez in first-line mCRPC than those with low levels. Testosterone can be considered a prognostic and predictive biomarker in this scenario, and could be used in treatment decision for this population.

Abstract Serum testosterone concentrations decrease in men with age, but benefits and risks of raising testosterone levels in older men remain controversial. In the T-Trials, a total of 790 men, age 65 and older, with a serum testosterone concentration of &lt; 275 ng/dL and symptoms of sexual dysfunction, fatigue or physical dysfunction were randomized to either testosterone gel or placebo gel for 1 year. Treatment in the testosterone arm increased serum testosterone levels to the mid-normal range for young men. Testosterone replacement was associated with a significant increase in sexual activity (p&lt;0.001), libido and erectile function. In contrast, there was no improvement in vitality or physical function. Adverse findings included increases in non-calcified plaque formation and a higher rate of prostate events. In sum, testosterone treatment in older men was associated with modest benefits, while the risk on prostate and cardiovascular health remain unclear.
