- It is estimated that 3-6% of all vasectomised men request vasectomy reversal for different reasons. Microsurgical vasovasostomy is the gold standard technique of vasectomy reversal. However, the microsurgical technique is time-consuming and challenging to most urological surgeons. Therefore, alternative methods of vasal anastomosis have been studied including robotic-assisted vasovasostomy. This review discusses the feasibility and practice of robotic-assisted vasovasostomy. Based on the available studies robotic-assisted vasovasostomy is feasible. The reported rate of vasal patency associated with this new technique is similar to that of microsurgical vasovasostomy. There is no clear difference between the 2 approaches in terms of operating time. Robotic-assisted vasovasostomy does not appear to afford significant advantages in the era of vasectomy reversal.

- Increased male age has been associated with significant reduction in pregnancy rates. This study investigated the association between age, the function of epididymal and accessory sex glands, and their relation to sperm motility. Ejaculates from 498 men assessed for infertility were analysed according to WHO [1999] guidelines. Seminal markers of epididymal (neutral alpha-glucosidase (NAG)), prostatic (prostate-specific antigen (PSA) and zinc), and seminal vesicle function (fructose) were measured. Four groups according to age were defined: G(21-30) (21-30 years), G(31-40) (31-40 years), G(41-50) (41-50 years), and G(> 50) (51-66 years). Percentage progressive motility was significantly lower in G(> 50) compared with G21-30. NAG, PSA, zinc, and fructose were significantly lower in G(> 50) compared with G21-30. In a multiple regression analysis model, NAG and PSA showed positive significant association with percentage progressive motility. The opposite trend was found regarding zinc. No association between fructose and percentage progressive motility was shown. In this cross-sectional study, declined sperm motility observed in men over 50 years of age might be due to age-dependent changes in epididymal and accessory sex gland function.

- Introduction: Epidemiological studies suggest atherosclerosis as a common risk factor between cardiovascular diseases and erectile dysfunction (ED). We aimed to determine the association between erectile function and the biomarkers of subclinical atherosclerosis in 119 middle-aged healthy men from the general population. Methods: Erectile function was assessed using the International Index of Erectile Function-5 (IIEF-5). Serum levels of biomarkers of atherosclerosis: Apolipoprotein A, Apolipoprotein B, fibrinogen, and C-reactive protein (CRP) were measured. In addition, demographic data was collected. Results: The mean (SD) of age was 55 years (± 4.0). The prevalence of ED was 50%. There was a negative significant correlation between IIEF-5 and CRP levels (r = -0.20, p = 0.02), and BMI (r = -0.20, p = 0.03), respectively. No significant correlations between IIEF-5 and serum levels of Apolipoprotein A, Apolipoprotein B, and fibrinogen were found (p > 0.05). A positive significant correlation was found between BMI and fibrinogen (r = 0.20, p = 0.01), CRP (r = 0.30, p = 0.001). In a multivariate logistic regression model with IIEF-5 as the dependent variable, CRP was the only biomarker that predicted ED (odds ratio = 1.350; 95 % CI: 1.044-1.754). Conclusions: These results indicate that CRP is a biomarker of subclinical atherosclerosis associated with ED. This association seems to be linked to greater BMI among such men.

- Introduction: This study was aimed to determine the association between PSA levels and biomarkers of subclinical systemic inflammation based on data from 119 middle-aged healthy men from the general population. Materials and Methods: Serum levels of PSA and biomarkers of systemic inflammation (CRP and fibrinogen) were measured. Demographic data were also collected. Subjects were divided into two groups according to PSA levels; < 2 ng/ml and ≥ 2 ng/ml. Results: The mean (SD) age of men was 55 ± 4.0 years. We found a positive significant correlation between PSA and fibrinogen levels (r = 0.20, p = 0.04), and between CRP and fibrinogen levels (r = 0.60, p = 0.01). On the other hand, no significant correlation between PSA and CRP levels was found. Men with PSA values ≥ 2 ng/ml had significantly higher levels of fibrinogen as compared to those with PSA < 2 ng/ml (2.9 ng/ml vs. 2.4 ng/ml, p = 0.01). In a multivariate regression analysis model adjusted for the age of subjects, BMI, marital status, smoking, snuff, and alcohol intake with serum levels of PSA as a dependent variable, serum level of fibrinogen predicted higher PSA-values (odds ratio = 3.30, 95% CI = 1.05-10.20, p = 0.042). Conclusions: The present results indicate that serum fibrinogen is a biomarker of subclinical systemic inflammation associated with PSA elevation among middle-aged healthy men from the general population.

- Introduction: The aim of the present study was to evaluate the association between serum testosterone and PSA levels in middle-aged healthy men from the general population. Materials and Methods: Based on 119 healthy men from the general population, total testosterone and PSA levels were measured. Demographic data regarding BMI, waist-to-hip ratio, smoking, and alcohol consumption were also collected. Men were classified into two groups according to testosterone levels; hypogonadal (testosterone ≤ 12 nmol/l), and eugonadal (testosterone > 12 nmol/l). Results: The mean age of the subjects was 55 years (range 46-60 years). No significant correlation between serum testosterone and PSA levels was found (p = 0.60). PSA levels were similar when compared between hypogonadal and eugonadal men (1.4 μg/l vs. 1.4 μg/l, p = 0.90).When using a multivariate analysis model adjusted for the age of the subjects, BMI, waist-to-hip ratio, smoking, and alcohol consumption, a positive significant association between testosterone and PSA levels was found (β = 0.03, 95 % CI = 0.003-0.062, p = 0.03). Conclusion: Only after adjusted multivariate analysis, our results indicated that testosterone was associated with PSA levels in middle-aged healthy men.

- OBJECTIVE: To investigate differences in semen quality between samples collected by masturbation at a clinic and at home. DESIGN: Cross-sectional study. SETTING: Fertility center. PATIENT(S): Three hundred seventy-nine men assessed for infertility. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Semen was analyzed according to World Health Organization guidelines. Seminal markers of epididymal (neutral alpha-glucosidase), prostatic (prostate-specific antigen and zinc), and seminal vesicle (fructose) function were measured. Two patient groups were defined according to sample collection location: at a clinic (n = 273) or at home (n = 106). RESULT(S): Compared with clinic-collected semen, home-collected samples had statistically significantly higher values for sperm concentration, total sperm count, rapid progressive motility, and total count of progressive motility. Semen volume, proportion of normal sperm morphology, neutral alpha-glucosidase, prostate-specific antigen, zinc, and fructose did not differ significantly between groups. An abnormal sperm concentration (<20 x 10(6)/mL) was seen in statistically significantly fewer of the samples obtained at home (19/106, 18%) than at the clinic (81/273, 30%), and the same applied to proportions of samples with abnormal (< 25%) rapid progressive motility (68/106 [64%] and 205/273 [75%], respectively). CONCLUSION(S): The present results demonstrate superior semen quality in samples collected by masturbation at home compared with at a clinic. This should be taken into consideration in infertility investigations.

- BACKGROUND: The data on the association between the abstinence period and sperm motility are conflicting. METHODS: Ejaculates from 422 men assessed for infertility were analysed according to the World Health Organization (WHO) guidelines. Seminal plasma neutral alpha-glucosidase (NAG), prostate-specific antigen (PSA), zinc and fructose were measured. Three groups were defined according to the length of sexual abstinence: G(2-3) (2-3 days), G(4-5) (4-5 days) and G(6-7) (6-7 days). RESULTS: The total percentage of progressively motile spermatozoa was significantly higher in G(4-5) compared with G(2-3) and G(6-7) (medians 55 versus 47 and 42%: P = 0.039 and P < 0.001, respectively). The percentage of spermatozoa with tail defects was significantly higher in G(6-7) compared with G(2-3) and G(4-5) (medians 14 versus 10 and 10%; P = 0.011 and P = 0.002. respectively). NAG was significantly lower in G(2-3) compared with G(4-5) and G(6-7) (medians 23 versus 34 and 34mU/ejaculate; P < 0.001 and P = 0.001, respectively). The same trend was found regarding zinc (medians 6 versus 8 and 8 mumol/ejaculate; P = 0.001 and P = 0.005, respectively). CONCLUSIONS: Within the time interval recommended by the WHO (2-7 days), the length of the abstinence period is associated with sperm characteristics and should be taken into consideration when interpreting results of semen analysis.

- Introduction: We aimed to evaluate the effectiveness of microsurgical subinguinal varicocele repair in patients with grade II-III lesions and chronic dull scrotal pain. Materials and Methods: A total of 29 patients with grade II-III varicocele and chronic dull scrotal pain that had a microsurgical subinguinal varicocele repair were included in the study. They were followed-up for 6-12 months including pain assessment and scrotal examination. Results: Of the 29 patients, 28 (97%) reported complete resolution of pain with no palpable varicocele on scrotal examination. No cases of testicular atrophy or hydrocele formation were reported. Conclusion: These results indicated that microsurgical varicocele repair should be considered in patients with grade II-III lesions and chronic dull scrotal pain.

- This study aimed to examine the association between the interval from ejaculation to analysis and epididymal and accessory sex gland function in relation to sperm motility. Ejaculates from 1079 men assessed for infertility were analyzed according to World Health Organization guidelines. Biochemical markers were measured in semen to assess the function of the epididymi;s (neutral alpha-glucosidase [NAG]), prostate (prostate-specific antigen [PSA] and zinc), and seminal vesicles (fructose). Three groups were defined according to time from ejaculation to analysis: G <= 30 (24 -30 minutes), G(31-60) (31-60 minutes), and G(>60) (63-80 minutes). The proportion of progressively motile sperm was significantly lower in G(>60) than in G(<= 30) (mean difference, 8.0%; 95% confidence interval [CI], 2.0%-13%) or G(31-60) (mean difference, 6.0%; 95% CI, 1.0%-12%). The proportion of rapid progressive sperm motility was significantly higher in G(<= 30) compared with G(31-60) (mean difference, 3.0%; 95% CI, 1.0%-5.0%) and 6160 (mean difference, 6.0%; 95% 3.0%; 95% 1.0%-10%). Sperm morphology and viability did not vary significantly between the groups. However, PSA levels in G(>60) were 29% and 31% significantly lower than in G(<= 30) (95% CI, 3.0%-54%) and G(31-60) (95% CI, 7.0%-58%), respectively. Moreover, men in G(>60) had 29% and 17% significantly lower zinc compared with those in G(<= 30) (95% CI, 4.0%-69%) and G(31-60) (95% CI, 4.0%-64%), respectively. Levels of NAG and fructose did not differ significantly between the groups. There were negative associations between the ejaculation-to-analysis interval and sperm motility and levels of PSA and zinc. In male infertility assessments, semen analysis should be performed within 60 minutes of ejaculation.
