RESUMO
BACKGROUND: To-date there have been minimal studies to investigate an association between the gut microbiome and erectile dysfunction. There have been many inflammatory diseases linked to gut microbiome dysbiosis; such as cardiovascular disease and metabolic syndrome. These same inflammatory diseases have been heavily linked to erectile dysfunction. Given the correlations between both conditions and cardiovascular disease and the metabolic syndrome, we believe that it is worthwhile to investigate a link between the two. OBJECTIVE: To investigate the potential association between the gut microbiome and erectile dysfunction. METHODS: Stool samples were collected from 28 participants with erectile dysfunction and 32 age-matched controls. Metatranscriptome sequencing was used to analyze the samples. RESULTS: No significant differences were found in the gut microbiome characteristics, including Kyoto Encyclopedia of Genes and Genomes richness (p = 0.117), Kyoto Encyclopedia of Genes and Genomes diversity (p = 0.323), species richness (p = 0.364), and species diversity (p = 0.300), between the erectile dysfunction and control groups. DISCUSSION: The association of gut microbiome dysbiosis and pro-inflammatory conditions has been well studied and further literature continues to add to this evidence. Our main limitation for this study was our small-sample size due to recruitment issues. We believe that a study with a larger population size may find an association between the gut microbiome and erectile dysfunction. CONCLUSIONS: The results of this study do not support a significant association between the gut microbiome and erectile dysfunction. Further research is needed to fully understand the relationship between these two conditions.

BACKGROUND: Despite increases in the lifetime prevalence of anal intercourse, little is known about the safety of inflatable penile prosthesis use during anal intercourse or the forces required for anal penetration. AIM: We sought to determine the force required for anal penetration. METHODS: A digital force gauge device was secured to a silicone phallus with a length and girth representative of the average male phallus in the United States and inserted into the anal canal of 6 male participants for a total of 5 measurements per participant. The maximum axial forces on insertion were recorded. Participants then completed a survey eliciting demographic information and past experience with receptive anal intercourse. OUTCOMES: The outcome measure was the force recorded during insertion of a force gauge device into the anal canal. RESULTS: The median maximal force recorded on anal penetration was 26.5 N (2.7 kg; range: 16.1-51.7 N or 1.64-5.27 kg). Participants who engaged in receptive anal intercourse more than once per month tended to use lesser median maximal forces (25.7 N or 2.62 kg) than participants who engaged less frequently in receptive anal intercourse (41.6 N or 4.24 kg). CLINICAL IMPLICATIONS: Compared with the forces required for vaginal penetration, anal penetration forces may cause additional mechanical stress to the phallus. STRENGTHS AND LIMITATIONS: While the study is limited primarily in its small sample size and in the use of a single device for anal penetration with a set size and rigidity, the resulting findings presented here are to our knowledge the first reported data pertaining the force required for anal penetration. CONCLUSION: As the forces required for anal penetration exceeded those for vaginal penetration, clinicians may need to carefully counsel patients on the safe use of an inflatable penile prosthesis for anal intercourse.

Purpose: While erectile dysfunction and urinary incontinence are commonly cited side effects following radical prostatectomy (RP), climacturia and penile length shortening are less explored. The present study seeks to explore the incidence, risk factors, and predictors of recovery associated with climacturia and penile length shortening following robot-assisted radical prostatectomy (RARP). Patients and Methods: From September 2018 to January 2020, 800 patients underwent RARP for primary treatment of localized prostate cancer. A survey was sent to patients following 1-year follow-up assessing outcomes of continence, erectile dysfunction, climacturia, and penile length shortening. Descriptive statistics were utilized to describe incidence and risk factors and logistic regression modeling was used to identify predictors associated with recovery. Results: Of the 800 patients surveyed, 339 (42%) and 369 (46%) patients responded, with 127/339 (37.5%) and 216/369 (58.5%) endorsing climacturia and penile length shortening. In univariate analysis, a lack of bilateral nerve sparing was associated with climacturia; high body mass index (BMI), high prostate weight, lack of nerve-sparing, and high pathologic stage was associated with penile length shortening. In logistic regression modeling, BMI, prostate weight, and p-stage were all significantly correlated with penile length shortening. Recovery from climacturia was associated with a preoperative International Index of Erectile Function-5 score >21. When patients were asked to rank the importance of these outcomes compared to erectile dysfunction and incontinence, <5% of patients ranked either climacturia or penile length shortening as a high priority following RP. Conclusion: While incidence of climacturia and penile length shortening following RP is significant, impact on patient- and partner-related quality of life are low in comparison to risks of erectile dysfunction and urinary incontinence.

After a focused telehealth visit, patients can now access phosphodiesterase-5 inhibitor (PDE5 inhibitor) prescriptions through online direct-to-consumer (DTC) healthcare companies. This study seeks to quantify the cost of DTC PDE5 inhibitor treatment compared to a traditional physician visit and local pharmacy prescription. Two DTC companies, two compounding pharmacies with national reach, three online Canadian pharmacies, and sixteen American pharmacy chains were queried for prices of 90-day regimens of common PDE5 inhibitors. Prices for chains were determined using their publicly available price on GoodRx® with coupon. Cost of physician visit was determined using 2020 Center for Medicare and Medicaid Services reimbursement for a level 3 new patient visit. For sildenafil 20 mg, a physician visit and local prescription cost a low of $125.45 compared to $144.35 for compounding, $169.34 for Canadian, and $195.00 for DTC. For sildenafil 100 mg, a physician visit and local prescription cost a low of $137.16 compared to $289.35 for compounding, $200.36 for Canadian, and $900.00 for DTC. For tadalafil 5 mg, a physician visit and local prescription cost a low of $125.80 compared to $169.35 for compounding, $195.34 for Canadian, and $720.00 for DTC. For tadalafil 20 mg, a physician visit and local prescription cost a low of $161.00 compared to $289.35 for compounding, $229.00 for Canadian, and $2880.00 for DTC. Thus, local pharmacies, in conjunction with online coupons, consistently provide a markedly less-expensive option for fulfillment of PDE5 inhibitor prescriptions than online DTC services.

OBJECTIVE: To comprehensively assess total and calculated free testosterone levels in a consecutive group of patients with prostate cancer (PCa) and any potential impact on disease aggressiveness and recurrence outcomes. PARTICIPANTS AND METHODS: The study included a single-centre prospective cohort of 882 patients presenting for radical prostatectomy from 2009 to 2018. Data on total testosterone (TT), sex hormone-binding globulin (SHBG), and calculated free testosterone (cFT) were prospectively collected. Stepwise logistic regression models were used to assess correlations of TT and cFT with pathological Gleason Grade Group (GGG), extraprostatic extension (EPE), seminal vesicle invasion (SVI) and biochemical recurrence (BCR). RESULTS: Total testosterone remained nearly constant across decades (40s-80s): 0.09 decrease/year (R = 0.02), while SHBG increased 0.87/year (R = 0.32) and cFT decreased 0.08/year (R = -0.02). Low cFT of <5.5 independently predicted: very-high-risk GGG (odds ratio [OR] 0.435, 95% confidence interval [CI] 0.846-0.994; P = 0.036), EPE (OR 0.557, 95% CI 0.810-0.987; P = 0.011), SVI (OR 0.396, 95% CI 0.798-1.038; P = 0.059), and BCR within 1 year after robot-assisted radical prostatectomy (OR 0.638, 95% CI 0.971-3.512, P = 0.046). TT was not a predictor. CONCLUSION: In contrast to popular belief, testosterone remained stable in men aged 40-80 years, whereas free testosterone decreased by 2-3%/year. Low cFT was an independent predictor of very-high-risk PCa and BCR.

PURPOSE: Intramuscular testosterone cypionate (IM-TC) is known to cause significant rises in estradiol (E2), hematocrit (HCT), and prostate specific antigen (PSA) due to its supraphysiological testosterone peaks, whereas a novel subcutaneous testosterone enanthate autoinjector (SCTE-AI) was designed with a lower testosterone peak-to-trough ratio to mitigate these reactions. We compare the total testosterone (TT), E2, HCT and PSA response to treatment with IM-TC versus SCTE-AI. MATERIALS AND METHODS: A total of 234 hypogonadal men were treated with testosterone replacement therapy (TRT) via IM-TC 100 mg weekly or SCTE-AI 100 mg weekly. TT, E2, HCT and PSA levels were obtained at baseline and 12 weeks post-treatment. Significant differences in baseline and post-treatment levels were identified by univariate analysis. Linear regression models determined whether treatment modality was independently associated with post-TRT levels of TT, E2, HCT and PSA. RESULTS: Post-TRT, both cohorts had significant increases in trough TT compared to their baseline levels (IM-TC: 313.6 ng/dL to 536.4 ng/dL, p <0.001; SCTE-AI: 246.6 ng/dL to 552.8 ng/dL, p <0.001). After linear regression, type of TRT modality was not found to be associated with TT levels (p=0.057). SCTE-AI was independently associated with lower post-therapy E2 (p <0.001) and HCT (p <0.001). Neither TRT modality was associated with significant post-therapy elevation of PSA (p=0.965). CONCLUSIONS: While IM-TC and SCTE-AI provide a significant increase in TT levels, SCTE-AI is associated with lower levels of post-therapy HCT and E2 compared to IM-TC after adjusting for significant covariates. SCTE-AI is an effective testosterone delivery system with a potentially preferable safety profile over IM-TC.

This study aimed to compare the change in levels of several laboratory values and the development of adverse events using two commonly used intramuscular testosterone therapy regimens. Men were included if they were 18 years or older and received one of the following testosterone therapy regimens: 100 mg intramuscular once weekly or 200 mg intramuscular once every other week. Primary outcomes were relative changes in total testosterone, free testosterone, estradiol, prostate-specific antigen, and hematocrit at 6 months after initiation of testosterone therapy. Secondary outcomes were any significant rises in estradiol, hematocrit, prostate-specific antigen, and any other treatment-related adverse events requiring cessation of testosterone therapy. A total of 263 men were enrolled. In a subanalysis of men who had a baseline hematocrit below 54% before intramuscular testosterone therapy initiation, we found the following: men who received 100 mg weekly injections were significantly less likely to have hematocrit levels rising above 54% (1/102 (1%) vs. 4/51 (8%); p = 0.023). No significant differences were recorded in the increase in total testosterone, free testosterone, prostate-specific antigen, and estradiol levels between both groups. A higher average serum testosterone over the dosing interval seen with the 200 mg regimen appears to be associated with a higher risk of erythrocytosis.

A subcutaneous testosterone enanthate-autoinjector (SCTE-AI) was recently approved by the Food and Drug Administration for patient-administered weekly testosterone replacement therapy (TRT). From January 2019 to October 2019, 110 hypogonadal men were treated with SCTE-AI at two institutions. Patients were assessed in a pretherapy visit prior to receiving SCTE-AI and re-assessed 6 weeks after treatment initiation. Patients with a history of prostate cancer were excluded. Trough serum total testosterone (TT), estradiol (E2), prostate-specific antigen (PSA), and hematocrit (HCT) levels were collected at clinic visits. Therapeutic phlebotomy was recommended for HCT > 54%, and treatment was discontinued for significant increases in PSA as well as for significant treatment-related adverse events. Values from each visit were compared with univariate analysis. 110 patients completed the 6 weeks of observation with a mean age of 40.3 (SD: 10.5). TT significantly rose from 246.6 ng/dL (SD:113.3) pretherapy to 538.4 ng/dL (SD: 209.3) at 6 weeks (p < 0.001). Post-therapy, 101/110 (91.8%) of patients had TT > 300 ng/dL. No patients had HCT > 54%. 74 patients (70.5%) had PSA increase with only 3 (2.9%) experiencing an increase >1.0 ng/dL. There was a significant increase in mean PSA from 1.07 ng/dL (SD: 0.8) pretherapy to 1.18 ng/dL (SD: 0.9) at 6 weeks (p = 0.01). One patient had immediate treatment cessation following diagnosis of prostate cancer. This is the largest non-industry sponsored safety and efficacy profile of SCTE-AI application in urology clinics. After 6 weeks of observation, TT levels increased significantly without any reports of adverse events. SCTE-AI is a safe and effective alternative delivery system of TRT.

BACKGROUND: No validated English language patient-reported outcome (PRO) currently exists that assesses satisfaction with inflatable penile prosthesis (IPP). Satisfaction data have been largely based primarily on surgeon assessment of patients or using questionnaires that have not been designed for this purpose. AIM: To develop an English-language validated PRO that assesses patient satisfaction after IPP surgery. METHODS: Initially, a literature review and discussions with experts defined domains important to IPP satisfaction (pain, appearance, function, overall satisfaction). The initial 35-item Satisfaction Survey for Inflatable Penile Implant (SSIPI) was developed. Cognitive interviews were then performed with IPP patients (n = 12) to gain feedback on the SSIPI domains and items. These data were used to modify SSIPI with the addition of 2 questions for a final item number of 37. Patients from 4 centers, who were between 6 months and 5 years after IPP, were administered the questionnaire through RedCap. Reliability statistics and content analysis were used to winnow questions to yield the final 16-item version of the SSIPI. Internal consistency was assessed via Cronbach's alpha and item-total correlation. Test-retest reliability was assessed via intraclass correlation coefficients using baseline and 2-week data. For convergent validity, the Erectile Dysfunction Inventory of Treatment Satisfaction and the Self-Esteem and Relationship (SEAR) questionnaire were used. For discriminant validity, the International Prostate Symptom Score (IPSS) was used. Confirmatory factor analysis was used to assess the factor structure of the SSIPI. OUTCOMES: Internal consistency, test-retest reliability, convergent and discriminant validity, and confirmatory factor analysis were assessed. RESULTS: 118 men were surveyed. Mean age was 66.8 ± 9.5 years. The 16-item SSIPI showed high internal consistency with an overall Cronbach's Alpha of 0.97 (domains 0.85-0.89). Item-total correlations for individual items to subscales ranged from 0.60 to 0.91. The overall test-retest reliability was 0.94 (domains 0.87-0.93). Erectile Dysfunction Inventory of Treatment Satisfaction and Self-Esteem and Relationship had correlations of 0.84 overall (domains 0.57-0.79) and 0.47 overall (domains 0.34-0.44), respectively. International Prostate Symptom Score (discriminant validity) had correlations of -0.29 overall (domains -0.17 to -0.31). CLINICAL IMPLICATIONS: SSIPI is the first English-language validated IPP satisfaction PRO. This will enable clinicians to collect satisfaction data in a standardized way. STRENGTHS AND LIMITATIONS: As strengths we have used a rigorous psychometric process and have no industry sponsorship. Limitations include small numbers of specific subpopulations. CONCLUSION: The SSIPI has demonstrated robust psychometric properties. Salter CA, Bach PV, Jenkins L, et al.

Defining risks associated with diabetes mellitus (DM) in patients undergoing penile prosthesis (PP) implantation remains controversial. This systematic review seeks to assess whether preoperative hemoglobin a1c (HbA1c) or serum glucose have been shown to predict infection following PP implantation in diabetic men. A stepwise literature search was performed. Eight and four studies assessing HbA1c and serum glucose respectively were included. Overall, data exploring HbA1c and serum glucose on PP infection were heterogeneous in time period, study design, and patient populations. Contemporary studies did not support either HbA1c nor blood glucose as predictors of PP infection in diabetic men.

The most dreaded complication of penile prosthesis (PP) implantation is device infection. We sought to assess whether inadequate cleaning and sterilization of the reusable Furlow inserter may represent one of the last etiologies of infection in PP patients. We performed a prospective analysis of cultures of the Furlow inserter used for PP surgeries from seven centers between May 1st and June 30th, 2019. Once the Furlow was received for surgery, the surgical team inspected the device for assembly status (disassembled or not) and the presence of visible stains, pieces of tissue or discoloration on either the interior of the barrel or the plunger. Swab aerobic and anaerobic bacterial and fungal cultures were then obtained from the internal component, after removal from the external component if assembled, and after introduction and immediate removal from the external component if disassembled. A total of 83 Furlow devices were cultured. Median age of surgical instrument was 4 years (2-10 years). Methods of sterilization included autoclave, wet autoclave, steam, and Sterad. Median time from sterilization was 3 days (1-22). On initial presentation, 79 devices were disassembled (95.1%) and 4 devices were still assembled (4.9%). Three external components were discolored (3.6%), while internal components demonstrated two stains (2.4%) indicative of improper cleaning which were thought to be residual blood products. Overall, 2/83 (2.4%) devices revealed positive swab cultures for Staphylococcus epidermidis. Swab cultures were negative for fungi and anaerobic bacteria. This patient cohort will continue to be followed to see if device infection occurs but it is unlikely to be meaningful since contaminated Furlows were discarded. Improper cleaning and/or sterilization of the Furlow Insertion Instrument may represent a source of infection for patients undergoing PP implantation.

Defining the risks associated with diabetes mellitus in patients undergoing penile prosthesis implantation remains controversial. Our study aims to assess whether preoperative hemoglobin a1c and preoperative blood glucose levels are associated with an increased risk for postoperative infection in diabetic men. We performed a retrospective review of 932 diabetic patients undergoing primary penile prosthesis implantation from 18 high-volume penile prosthesis implantation surgeons throughout the United States, Germany, Belgium, and South Korea. Preoperative hemoglobin a1c and blood glucose levels within 6 h of surgery were collected and assessed in univariate and multivariate models for correlation with postoperative infection, revision, and explantation rates. The primary outcome is postoperative infection and the secondary outcomes are postoperative revision and explantation. In all, 875 patients were included in the final analysis. There were no associations between preoperative blood glucose levels or hemoglobin a1c levels and postoperative infection rates; p = 0.220 and p = 0.598, respectively. On multivariate analysis, a history of diabetes-related complications was a significant predictor of higher revision rates (p = 0.034), but was nonsignificant for infection or explantation rates. We conclude preoperative blood glucose levels and hemoglobin a1c levels are not associated with an increased risk for postoperative infection, revision, or explantation in diabetic men undergoing penile prosthesis implantation.

Men's Health is a urological subspecialty that is at the forefront of innovation, but little data exist evaluating the attitudes that andrologists have toward the current treatment modalities available for managing Men's Health conditions. A survey of 37 questions asking what providers would choose as treatment for common conditions was distributed online via Survey Monkey to members of the Sexual Medicine Society of North America and European Society for Sexual Medicine. A total of 115 respondents completed the survey after an initial screening question. For erectile dysfunction (ED), 40%, 38%, and 33% of providers indicated that they would use tadalafil daily, tadalafil on demand, or sildenafil on demand, respectively, as first-line phosphodiesterase 5 inhibitor therapy. Furthermore, a total of 74% would elect to undergo low-intensity shockwave therapy [67%], platelet rich plasma injections [15%], and stem cell injections [15%]. Sex/behavioral therapy was preferred for both premature (36%) and delayed (52%) ejaculation. Approximately 44% of respondents indicated that they would undergo Collagenase Clostridium Histolyticum injections for Peyronie's Disease in the acute phase. In the setting of hypogonadal symptoms with borderline low total testosterone levels (300-400 ng/dL), 69% of respondents would pursue testosterone therapy. The prostatic lift procedure was the preferred procedure for men seeking symptom resolution with preservation of ejaculatory function. Many Men's Health specialists would pursue the least invasive options before considering procedural intervention for any given condition. Providers may shift their treatment preferences toward newer treatment modalities as longer term data become available.

INTRODUCTION: Peyronie's disease (PD) is an inflammatory disorder of the tunica albuginea causing fibrotic changes including abnormal penile curvature, pain, and erectile dysfunction. Approximately 10% of PD patients will have atypical features including ventral plaques, hourglass deformities, unilateral indentations, severely shortened penile length, and multiplanar curvatures. Currently, the only intralesional treatment approved by the United States Food and Drug Administration is considered off-label for atypical PD. Furthermore, treatment of atypical PD, especially ventral plaques, is met with hesitation, in part due to potential urethral injury. OBJECTIVES: To systematically review the available literature for the safety and efficacy of intralesional injections for atypical PD. METHODS: A thorough literature search of the PubMed database was performed on manuscripts published between 1982 and 2020. Keywords included atypical Peyronie's disease, ventral plaque, hourglass deformity, and injection. RESULTS: 15 articles met the criteria for evaluation. Overall, 1,357 patients with PD were treated with intralesional therapy, of which 250 patients were considered to have an atypical presentation. 162 (648%) of the patients were treated with intralesional collagenase Clostridium histolyticum, 49 (19.6%) with verapamil, 29 (11.6%) with interferon alfa-2b, 5 (2.0%) with hyaluronic acid, and another 5 (2.0%) with onabotulinumtoxinA. There was only 1 reported severe adverse event (penile fracture), which was surgically repaired. There were no reports of urethral injury. CONCLUSION: Intralesional injection treatment may be a safe alternative option for atypical PD. There is a great need for future research to closely monitor the role of intralesional therapy in this cohort. Choi EJ, Xu P, El-Khatib FM, et al.

Adult-onset hypogonadism (AOH) is associated with sexual dysfunction, poor bone mineralization, decreased muscle mass, metabolic syndrome disorder, and cognitive suppression. Historically, testosterone has been contraindicated in men with a history of prostate cancer. However, there has been a modern resurgence in re-evaluating this belief. Not only can testosterone be safely utilized to alleviate AOH symptoms in prostate cancer survivors, it has been also touted as a treatment option for aggressive prostatic cancer. While much work remains in understanding the relationship between testosterone and prostate cancer, those who survive this disease should not be automatically turned away from an opportunity to be treated and restored.

BACKGROUND: Modern-day penile prostheses use infection retardant coating to decrease rates of postoperative infection, subsequently reducing explantation and revision rates as well. The Coloplast Titan models are dipped into antimicrobial solutions right before implantation, and the components used for dipping can be tailored toward the patient. AIM: To compare infection, explantation, and revision rates among different dipping solutions used before implantation for patients with diabetes receiving a Coloplast Titan implant. METHODS: We systematically reviewed 932 patients with diabetes receiving a primary penile implant across 18 different centers from the period April 2003 to August 2018. Of those patients, 473 received a Coloplast device, whereas 459 received an AMS device. Data regarding the type of antimicrobial solution used before implantation were recorded for 468 patients receiving a Coloplast Titan, including whether or not they suffered a postoperative infection and if they underwent explantation and/or revision. Outcome rates were compared using Fisher's exact and Pearson's chi-square tests, and logistic regression modeling was performed to account for covariates. OUTCOMES: The main outcome measures of this study were postoperative infection, explantation, and revision rates. RESULTS: Of the total 932 patients reviewed, 33 suffered a postoperative infection. Of 468 patients receiving Coloplast implants, there was a 3.4% infection rate. The most commonly used antibiotic combination before dipping was vancomycin + gentamicin (59.0%). There was a significantly lower rate of postoperative infection, explantation, and revision when vancomycin + gentamicin was used than those associated with the use of all other dipping solutions ([1.4% vs 6.4%; P = .004], [1.1% vs 8.3%; P < .001], and [2.5% vs 12.5; P < .001], respectively). After adjusting for age, body mass index, preoperative blood glucose level, and hemoglobin A1c, the use of other dips was an independent predictor of postoperative infection (odds ratio: 0.191; P = .049). The inclusion of rifampin in the dipping solution trended toward being a significant risk factor for infection (P = .057). Including antifungals in the dipping solution did not affect infection (P = .414), explantation (P = .421), or revision (P = .328) rates. CLINICAL IMPLICATIONS: Vancomycin + gentamicin was the most efficacious combination of antibiotics used for dipping in terms of preventing postoperative infection and subsequent explantation and revision. STRENGTHS AND LIMITATIONS: Data were sampled across multiple institutions providing a large sample that may be more representative of the population of interest. A key limitation of the study was its retrospective nature, which prevented us from controlling certain variables. CONCLUSION: The use of rifampin did not provide the same type of protection, possibly representing a shift in resistance patterns of common bacteria responsible for device infection.
