Objective: COVID-19, which is known to be caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is a global health problem that can cause multiorgan damage because of its use of the angiotensin-converting enzyme 2 (ACE2) receptor in its pathophysiology. We aimed to investigate whether SARS-CoV-2 had a short-term effect on spermatogenesis, which plays an important role in male reproductive health as it has abundant ACE2 expression in testicular tissue. Material and methods:This multicenter study included 69 patients aged 20-45 years, who admitted to our hospitals between April 2020 and October 2020 with a history of a positive test result for SARS-CoV-2 based on the nasopharyngeal or oropharyngeal swab samples and had recovered from the disease at least three months earlier and who had undergone a spermiogram test in the hospital database within the last year before the onset of disease. The patients were divided into two groups according to their COVID-19 symptoms being mild or moderate, depending on whether they had received home treatment or required hospitalization for oxygen therapy. Semen samples taken before and after COVID-19 were compared within and between the groups in terms of sperm parameters. Results:The mean age of the patients included in the study was 30.4±4.8 years in the mild symptomatic COVID-19 group and 31.06±4.2 years in the moderate symptomatic group. When the spermiogram samples of the patients before and after COVID-19 were evaluated, it was found that motility and vitality significantly decreased in the mild symptomatic group, while the decrease in all semen parameters was statistically significant in the moderate symptomatic group. Conclusion:Although the mechanism by which COVID-19 causes testicular involvement remains uncertain, its short-term results on spermatogenesis reveals that COVID-19 negatively affects sperm parameters.
This study measured the serum folic acid (FA) level in patients with erectile dysfunction (ED) and evaluated the possible association between the serum FA level and erectile function. The study divided 120 patients with ED into 3 groups of 40 patients each: those with severe, moderate and mild ED. Forty healthy men served as controls. Fasting serum samples were obtained, and the total testosterone, cholesterol and FA levels were measured using chemiluminescent immunoassays. There were no significant differences in the mean age, mean body mass index or mean serum total testosterone and cholesterol levels among the three ED groups and controls (P > 0.05). The mean serum FA concentrations were 7.2 ± 3.7, 7.1 ± 3.2, 10.2 ± 4.6 and 10.7 ± 4.6 ng ml(-1) in the severe, moderate and mild ED and control groups respectively. The mean serum FA concentration was significantly higher in the control group than in the severe and moderate ED groups (both P < 0.001), but not the mild ED group (P = 0.95). Considering the significant differences in the serum FA levels between the control and ED groups, serum FA deficiency might reflect the severity of ED.
Studies show that erectile dysfunction (ED) is associated with obesity, and it has been shown that the possibility of developing sexual dysfunction in obese men is 30% higher compared to those with normal weight. Obesity is measured using various methods, for example waist circumference (WC) measurement or body mass index (BMI), but recently, visceral adiposity index (VAI) has also been utilised to better assess obesity and metabolic syndrome. In our study, the potential link between VAI and ED was investigated. The data of 176 patients who presented to the urology outpatient clinic with erection complaints were retrospectively screened. A control group was also established with 122 men without complaints of erectile dysfunction. The erectile functions of all participants were determined using the International Erectile Function Index‐5 (IIEF‐5) scoring. In addition, their serum fasting blood glucose, total testosterone (TT), triglyceride (TG), low‐density lipoprotein (LDL) cholesterol and high‐density lipoprotein (HDL) cholesterol levels were measured. The physical examination comprised the measurement of WC, height and weight, and BMI. The mean age of the participants was 58.7 ± 8.4 for the ED group and 57.1 ± 7.5 for the control group. The mean VAI was statistically significantly higher in the ED group (5.32 ± 2.77) compared to the control group (4.11 ± 1.93) (p < 0.001). Since VAI contains both physical and metabolic parameters, our findings suggest that it discloses the effects of WC, BMI, HDL and TG more clearly. VAI is considered useful for the assessment of the effect of obesity on ED patients.
This study was conducted to investigate the prevalence of premature ejaculation (PE) in young Turkish men and to evaluate PE in a population having good physical and mental health. A total of 1230 healthy university graduates aged between 24 and 30 attending the police academy having no physical or mental problems were included in the study. To identify the presence of PE, the participants were asked to complete the premature ejaculation diagnostic tool (PEDT). The mean ages in the PE and non-PE group were 27.3 and 26.7 respectively. There was no statistically significant difference between the two groups concerning age, body mass index (BMI), smoking status and alcohol consumption (P > 0.05). The PE prevalence was found to be 9.2%. The mean PEDT score was calculated as 6.3. Of the participants, 92 scored 11 and higher (9.2%), 66 scored 9 and 10 (6.6%), and the remaining 842 obtained a score equal to or lower than 8 (84.2%). The lower prevalence of PE in young Turkish men compared to the results of studies in the literature can be attributed to the physical and mental well-being of the participants. This study showed that the prevalence of PE in young men with good physical and mental health is lower than that found in the literature.
We investigated the effect of spinal anesthesia combined with obturator nerve block (ONB) during the transurethral resection of lateral bladder wall tumors (TUR-BT) on the presence of detrusor muscle tissue in tumor specimens and on tumor recurrence. TUR-BT was performed on 96 patients with a lateral bladder wall tumor under spinal anesthesia in our clinic between January 2011 and December 2015. The patients were divided into two groups: 49 patients only received spinal anesthesia and 47 patients received spinal anesthesia combined with ONB. The groups were retrospectively compared in terms of adductor muscle contraction, bladder perforation, complete tumor resection, presence of muscle tissue in the pathology material, and recurrence rate during follow-up. The obturator reflex was significantly observed in the non-ONB group (p < 0.05). In the ONB group, the percentages of complete resection and detrusor muscle tissue were significantly higher (p = 0.003 and p = 0.001, respectively). The postoperative recurrence rate was found to be significantly higher in the non-ONB group than in the ONB group (p = 0.025). Spinal anesthesia combined with ONB during TUR-BT prevent obturator reflex and facilitate complete resection including detrusor muscle tissue, independent from the size or number of tumors, thus reducing the recurrence of the disease.
Introduction: Prostatic urethral lift (PUL) is a minimally invasive procedure for the treatment of lower urinary tract symptoms (LUTSs) secondary to benign prostatic hyperplasia (BPH). The PUL procedure involves the placement of implants that retract the obstructing prostate lobes. This procedure achieves quantifiable improvements in functional outcomes and quality of life (QoL), while preserving erectile and ejaculatory functions. Methods: Seventeen patients diagnosed with BPH who had undergone the UroLift® procedure between March 2011 and June 2015 were retrospectively evaluated. The parameters evaluated in the pre-operative, intra-operative and 1-year post-operative period were demographic data, and pre-operative, intra-operative and 1-year post-operative results were obtained from the International Prostate Symptom Score (IPSS), Uroflowmetry QoL index, International Index of Erectile Function (IIEF) and Male Sexual Health Questionnaire (MSHQ) for ejaculatory function (MSHQ-EjD). Results: The average improvements from baseline to 12 months after intervention were significant for the total IPSS 9.6. There was a 4.2-point increase in Qmax, a 0.9-point improvement in QoL and a 32% decrease in PVR. No statistically significant difference was found in the IIEF and MSHQ-EjD scores when the pre-operative and post-operative 3rd and 12th month scores were evaluated (p > 0.05). Conclusions: PUL offers rapid improvement in voiding and storage symptoms, QoL and flow rate that is durable to 12 months after intervention. PUL is a minimally invasive procedure that has the moderate effect in treating troublesome LUTS secondary to benign prostatic obstruction and preserving total sexual function.
Objectives The aim of this study was to assess the possible role of HPV in the development of prostate cancer (PCa) and investigate the distribution of the p53 codon 72 polymorphism in PCa in a Turkish population.Materials and methods A total of 96 tissues, which had been obtained using a radical surgery method, formalin-fixed and parafin-embedded, were used in this study. The study group consisted of 60 PCa tissues (open radical prostatectomy) and the control group contained 36 benign prostatic hyperplasia tissues (BPH) (transvesical open prostatectomy). The presence of HPV and the p53 codon 72 polymorphism was investigated in both groups using real-time PCR and pyrosequencing.Results The results of the real-time PCR showed no HPV DNA in any of the 36 BPH tissue samples. HPV-DNA was positive in only 1 of the 60 PCa samples (1.7%). The HPV type of this sample was identified as HPV-57. The distribution of the three genotypes, Arg/Arg, Arg/Pro and Pro/Pro was found to be 45.6, 45.6, and 8.8% in the PCa group and 57.1%, 34.3% and 8.6% in the control group, respectively. Compared with the control group, patients with PCa had a higher frequency of the Arg/Pro genotype and Proline allele (odds ratio (OR)=1.67, 95% confidence interval (CI)=0.68-4.09, p=0.044; OR=1.13, 95% CI=0.76-1.68, p=0.021, respectively).Conclusions The results of the study do not support the hyphothesis that prostate cancer is associated with HPV infection but indicated that Proline allele can be a risk factor in the development of PCa in the Turkish population.
