Urine microbes and predictive metagenomic profiles associate with abnormalities in sperm parameters: implications for male subfertility. F&S SCIENCE 2024; 5:163-173. [PMID: 38336233 DOI: 10.1016/j.xfss.2024.01.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Revised: 01/31/2024] [Accepted: 01/31/2024] [Indexed: 02/12/2024]
Abstract
OBJECTIVE To explore the taxonomic and predicted functional relationship between the urine microbiome and alterations of semen analysis (SA) parameters. DESIGN Cross-sectional study. SETTING Academic medical center. PATIENT(S) Men presenting for fertility evaluation or men presenting for vasectomy consultation with proven biological paternity were recruited and stratified on the basis of alterations, or lack thereof, in SA parameters. MAIN OUTCOME MEASURE Changes in the functional and taxonomic urine microbiome profiles of participants with or without alterations in SA parameters. RESULTS Seventy-three participants were included in our study. Men with abnormal sperm motility (N = 27) showed a nearly 50-fold higher abundance of Dialister micraerophilus compared with those with normal sperm motility (N = 46). This relationship persisted on canonical correlational analysis (r = 0.439). Men with abnormal sperm concentration (N = 20) showed a lower abundance of Enterococcus faecalis and Staphylococcus aureus, compared with those with normal sperm concentration (N = 53). The urine of participants with impaired sperm motility demonstrated dramatic differences in predictive functional profiles in pathways involved in oxidation-reduction balance and cell longevity. CONCLUSIONS Our findings underscore differences in the urinary microbiome and abnormalities in semen parameters, especially sperm motility. By incorporating predictive functional profiling, we also highlight possible mechanisms that may drive the observed differences in sperm parameters.

Patient-Directed Vasectomy Information: How Readable Is It? World J Mens Health 2024; 42:408-414. [PMID: 37853530 PMCID: PMC10949024 DOI: 10.5534/wjmh.230033] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 04/17/2023] [Accepted: 04/25/2023] [Indexed: 10/20/2023] Open
Abstract
PURPOSE To assess the quality and readability of online health information on vasectomy using validated readability and quality assessment tools. MATERIALS AND METHODS The top 50 search results for "vasectomy" on Google, Bing, and Yahoo were selected. Duplicate links, advertisements, blog posts, paid webpages, and information intended for healthcare providers were excluded. Flesch Reading Ease score, Flesch-Kincaid Grade level, Gunning Fog Index, and Simple Measure of Gobbledygook (SMOG) index were used to assess readability, with optimal readability level for online health information established as being at sixth grade reading level. DISCERN Instrument and JAMA Benchmark were used to assess the quality of selected webpages. Inter-assessment score correlation and results by webpage type were analyzed. RESULTS We analyzed 44 webpages, including 16 academic, 5 hospital-affiliated, 6 commercial, 13 non-profit health advocacy, and 4 uncategorized sources. The average readability of the evaluated webpages was at a 10th grade reading level as measured by the Flesch Kincaid Assessment tool, and an undergraduate reading level per the SMOG and Gunning Fog indices. Non-profit health advocacy webpages had the best reading level but still was not at the recommended level of grade 6 to 7. The overall DISCERN quality of the webpages was "fair", with non-profit health advocacy pages performing best. CONCLUSIONS The assessed webpages offer education on vasectomy in a language that is too complex for the general population to understand. Furthermore, several sources for online health information, such as non-profits, outperformed webpages by academic institutions. Increased healthcare collaboration and dedication to producing quality online patient resources is necessary to address these shortcomings and build trust among patients to increase utilization of vasectomy and decrease decisional regret.

Collagenase Clostridium histolyticum for Peyronie's disease: a contemporary atlas of complications and their management. Sex Med Rev 2024:qeae004. [PMID: 38491199 DOI: 10.1093/sxmrev/qeae004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 01/16/2023] [Accepted: 01/21/2023] [Indexed: 03/18/2024]
Abstract
INTRODUCTION Collagenase Clostridium histolyticum (CCH) remains the only Food and Drug Administration-approved medical treatment for Peyronie's disease (PD). The initial IMPRESS I and II trials (Investigation for Maximal Peyronie's Reduction Efficacy and Safety), which led to Food and Drug Administration approval, revealed a rate of treatment-related adverse events as high as 84%. Studies fail to provide clear definitions of complications. OBJECTIVES To review complications, provide a CCH complication atlas, and propose management strategies for commonly encountered complications. METHODS We performed a literature review using PubMed. A photographic atlas was provided regarding complications in patients in a high-volume CCH center for PD. RESULTS Complications were identified and classified by nature and severity. We followed a standardized previously published grading system for hematomas. Complications include bruising, swelling, hematoma formation, back pain, and, rarely, corporal rupture. Complications were discussed, and hematomas were graded by penile surface area. Complication photographs were graded and displayed. Treatment-related adverse effects do not affect overall results. CONCLUSION Recognizing and grading complications associated with CCH therapy for PD is crucial for effective patient management and informed decision making. A standardized grading system allows for consistency in reporting and comparing hematoma complication rates across studies and patient populations. Herein we provide images that will help clinicians identify and confidently manage common complications that may occur in any CCH program.

Semen microbiota are dramatically altered in men with abnormal sperm parameters. Sci Rep 2024; 14:1068. [PMID: 38212576 PMCID: PMC10784508 DOI: 10.1038/s41598-024-51686-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2023] [Accepted: 01/08/2024] [Indexed: 01/13/2024] Open
Abstract
There has recently been an explosion of studies implicating the human microbiome in playing a critical role in many disease and wellness states. The etiology of abnormal semen analysis (SA) parameters is not identified in 30% of cases; investigations involving the semen microbiome may bridge this gap. Here, we explore the relationship between the semen microbiome and alterations of sperm parameters. We recruited men presenting for fertility evaluation or vasectomy consultation with proven biological paternity. SA and next generation sequencing was performed. Differential abundance testing using Analysis of composition of Microbiota with Bias Correction (ANCOM-BC) was performed along with canonical correlational analysis for microbial community profiling. Men with abnormal (N = 27) sperm motility showed a higher abundance of Lactobacillus iners compared to those with normal (N = 46) sperm motility (mean proportion 9.4% versus 2.6%, p = 0.046). This relationship persisted on canonical correlational analysis (r = 0.392, p = 0.011). Men with abnormal sperm concentration (N = 20) showed a higher abundance of Pseudomonas stutzeri (2.1% versus 1.0%, p = 0.024) and Pseudomonas fluorescens (0.9% versus 0.7%, p = 0.010), but a lower abundance of Pseudomonas putida (0.5% versus 0.8%, p = 0.020), compared to those with normal sperm concentration (N = 53). Major limitations are related to study design (cross-sectional, observational). Our results suggest that a small group of microorganisms may play a critical role in observed perturbations of SA parameters. Some of these microbes, most notably Lactobacillus iners, have been described extensively within other, fertility-related, contexts, whereas for others, this is the first report where they have potentially been implicated. Advances in our understanding of the semen microbiome may contribute to potentially new therapeutic avenues for correcting impairments in sperm parameters and improving male fertility.

Abstract
The surgical management of prostate cancer through radical prostatectomy has the potential to impact patients' sexual function, including erectile dysfunction and Peyronie's disease (PD). Historical data suggests the incidence of PD in post-prostatectomy patients is higher than in the general population at 15.9%. Our study objective was to measure the rate of the development of PD among patients that receive penile rehabilitation (PR) regimen prior to and immediately after radical prostatectomy. In this study, we retrospectively reviewed the charts of 581 patients who were diagnosed with prostate cancer, treated with radical prostatectomy, and engaged in a PR program. Patients with the diagnosis of PD prior to prostatectomy were excluded from this study. The PR program consists of daily tadalafil, L-citrulline, and weekly vacuum erectile device with the option of intracavernosal injections if patients fail to respond to the regular regimen. We found the incidence of PD to be 2.9%, suggesting that PR regimens programs may be associated with a reduced incidence of PD in post-prostatectomy patients. Ten (out of 17) patients were diagnosed with PD after 2 years of follow up. The return of erections was not statistically different among patients who developed PD and the rest of the patients. Prospective, multi-institutional trials will be required to elucidate whether PR can prevent the development of PD in this patient population.

Should I freeze my sperm?-readability and quality of health resources for sperm banking. Transl Androl Urol 2023; 12:1561-1567. [PMID: 37969777 PMCID: PMC10643385 DOI: 10.21037/tau-23-120] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Accepted: 07/19/2023] [Indexed: 11/17/2023] Open
Abstract
Background Sperm banking refers to the collection and storage of sperm cells for future use. Despite the recommendations of major medical societies, sperm banking is not discussed sufficiently with patients at risk of future fertility. Majority of Americans utilize the internet regarding health information. The aim of this study is to assess the reading level and the quality of online health information on sperm banking. Methods The top 50 search results from Google, Bing, and Yahoo were selected after searching for the term "sperm banking". Duplicate pages, advertisements, news and magazines, blog posts, videos, paid subscriptions, articles intended for health professionals, and non-related pages were excluded. Four validated readability and two quality assessment tools were used to score the text. Websites were divided into five categories: academic, hospital-affiliated, commercial, non-profit health advocacy, and non-categorized. Descriptive statistics, one sample t-test, and Pearson's correlation coefficient were used to analyze the data. Results Forty-one webpages were included. The mean Flesch Reading Ease Score (FRES) for all pages was 46.9/100 and the mean reading level was 11th grade, compared to the recommended 6th grade level, across various assessment tools. Utilizing the DISCERN Instrument, quality of online health information was fair. Seven percent of pages received a "good" quality score and no pages received a score of "excellent". On average, 1.5 out of 4 criteria categorized by the JAMA Benchmark, a validated quality assessment tool, were met. The hospital-affiliated webpages received the best reading scores and commercial pages received the highest quality scores. Conclusions Online health information on sperm banking available in English is of poor quality based on several quality assessment tools and at a reading level significantly higher than what is recommended. Further efforts are needed by providers and healthcare institutions to improve the quality of information available to patients.

Testosterone and luteinizing hormone predict semen parameter improvement in infertile men treated with anastrozole. Fertil Steril 2023; 120:746-754. [PMID: 37392782 DOI: 10.1016/j.fertnstert.2023.06.032] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 06/22/2023] [Accepted: 06/26/2023] [Indexed: 07/03/2023]
Abstract
OBJECTIVE To identify patient factors associated with a clinically significant improvement in semen parameters among infertile men treated with the aromatase inhibitor anastrozole. DESIGN Multi-institutional retrospective cohort study. SETTING Two Tertiary Academic Medical Centers. PATIENTS A total of 90 infertile men treated at 2 tertiary academic medical centers who met inclusion criteria and obtained pretreatment and posttreatment semen analyses. INTERVENTION Prescription of anastrozole (median 3 mg/wk). MAIN OUTCOME MEASURES Upgrade in the World Health Organization sperm concentration category (WHO-SCC). Univariate logistic regression, multivariable logistic regression, and partitioning analyses were performed to identify statistically significant patient factors capable of predicting treatment response. RESULTS With anastrozole treatment, 46% (n = 41/90) of men responded favorably with a WHO-SCC upgrade, and 12% (n = 11/90) experienced a downgrade. Responders exhibited lower pretreatment levels of luteinizing hormone (LH, 4.7 vs. 8.3 IU/L) and follicle-stimulating hormone (4.7 vs. 6.7 IU/mL), higher pretreatment levels of testosterone (T, 356 vs. 265 ng/dL), and similar baseline level of estradiol (E2, 73% vs. 70% with detectible level). Baseline semen parameters differed, with anastrozole responders demonstrating higher baseline semen concentration (3.6 vs. 0.3 M/mL) and higher total motile sperm counts (3.7 vs. 0.1 M). Anastrozole therapy converted 29% (n = 26/90) of the cohort to normozoospermia and enabled intrauterine insemination access in 31% (n = 20/64) of previously ineligible patients. Interestingly, neither body mass index nor the baseline E2 level or E2-T ratio was associated with WHO-SCC upgrade. Multivariable logistic regression revealed the T-LH ratio (odds ratio: 1.02, 95% confidence interval: 1.00-1.03) and baseline nonazoospermia (odds ratio: 9.4, 95% confidence interval: 1.1-78.9) to be statistically significant predictors of WHO-SCC upgrade (area under receiver operating characteristic curve: 0.77). The final user-friendly partitioning model consisting of the T-LH ratio ≥100 and baseline non-azoospermia was 98% sensitive and 33% specific for WHO-SCC upgrades (area under the curve: 0.77). CONCLUSION Anastrozole therapy decreases serum E2 levels, increases serum gonadotropins, and clinically improves semen parameters in half of men with idiopathic infertility. Nonazoospermic infertile men with T-LH ratios ≥100 are likely to benefit from anastrozole treatment irrespective of baseline E2 level or E2-T ratio. Men with azoospermia rarely respond to anastrozole and should be counseled on alternative treatments.

Regenerative therapies for erectile dysfunction: the influence of direct-to-consumer marketing on patient interest. Transl Androl Urol 2023; 12:586-593. [PMID: 37181238 PMCID: PMC10170274 DOI: 10.21037/tau-22-309] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2022] [Accepted: 01/08/2023] [Indexed: 03/21/2023] Open
Abstract
Background Despite a lack of evidence, a number of "regenerative" therapies have become popularized treatments for erectile dysfunction (ED). Platelet-rich plasma (PRP) injections and shockwave therapy have received significant attention through direct-to-consumer marketing and are advertised as viable alternatives to guideline-backed therapies. Additionally, focused low-intensity shock wave therapy (LiSWT) has become conflated with acoustic or radial wave therapy (rWT), although their mechanism of wave generation and tissue penetration is distinct. GAINSWave, a marketing platform for acoustic wave therapy, has also pervaded the marketplace. We aim to evaluate the relative impact of direct-to-consumer marketing of shockwave therapy and PRP by analyzing the quantity of Google internet search queries for selected regenerative and guideline-backed non-regenerative therapies for ED. Methods National Google Search trends in the United States (www.google.com/trends) were analyzed to characterize interest in different forms of therapy for ED. Search trends for PRP, LiSWT (and various iterations), intracavernosal injections (ICI), intraurethral injections (IU), vacuum erectile device (VED), and GAINSWave were analyzed. Monthly search data were compiled over multiple years, ending at 2/28/2020, just before the COVID-19 pandemic and state of emergency in the United States. Macro-level changes in public interest were quantified using yearly averages. Results Patterns in Google Search interest in PRP and LiSWT increased respectively by 3-fold and 275-fold over the decade, representing a larger share of Google Searches by 2020. Trends in Google Search interest in selected types of shockwave therapy for ED also show that queries for GAINSWave commanded public interest, increasing by 219-fold from 2016 to 2020. Conclusions Regenerative therapies for ED have produced interest surpassing other adjunct guideline-backed therapies, despite receiving the designation of "experimental" or "investigational" therapies. The establishment of GAINSWave also constitutes an inflection point for the whole shockwave market: searches for shockwave therapy increased by 782% between 2016 and 2020. Direct-to-consumer marketing of PRP and shockwave therapy has upturned the customary role of physicians in counseling patients about evidence-based therapies for ED. This increase in public interest in GAINSWave emphasizes its success as a marketing platform. The urological community should consider strategies to address misinformation, such as search-engine optimization, social media, and educational outreach.

Guideline-Nonconformant Investigational Treatments for Erectile Dysfunction: What are Patients Learning? Urology 2023; 173:111-118. [PMID: 36584789 DOI: 10.1016/j.urology.2022.11.044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2022] [Revised: 11/07/2022] [Accepted: 11/10/2022] [Indexed: 12/28/2022]
Abstract
OBJECTIVE To evaluate the validity of YouTube content on shockwave, platelet-rich plasma, and stem cell therapies for erectile dysfunction (ED). The consumerization of men's health is particularly notable among regenerative ED treatments, and the popularity of these treatments has been amplified by social media sites such as YouTube. METHODS We searched YouTube utilizing the following terms: "shockwave therapy-," "platelet-rich plasma- and "stem cell therapy-" "-for erectile dysfunction." The first 50 resulting videos per query were screened (inclusion criteria: relevant title/content, English language, >100 views) and judged by 2 independent graders using the validated DISCERN instrument for consumer health information. Regression analysis assessed association of video characteristics with DISCERN score. RESULTS Seventy-one unique videos met criteria. More content featured non-physicians (37%) or non-urologist physicians (35%) than urologists (28%). Mean DISCERN score was low at 42.8 of 80. DISCERN score significantly differed by video category and characteristics. Educational and urologist-featuring videos were associated with higher score. News reports were associated with lower score. Only 3 videos mentioned investigational/experimental status of the therapies. Only 2 cited society guidelines. CONCLUSION Most YouTube videos on regenerative ED therapies are unreliable and from non-urologists. The misrepresentation of proven efficacy may be encouraging patients to seek these still investigational treatments at high fiscal costs to the patient. Videos with urologists were more likely to be higher quality and guideline based. The urological and academic communities should continue to leverage the power of social media to provide evidence-backed consumer health information in this space.

Multiple courses of intralesional collagenase injections for Peyronie disease: a retrospective analysis. J Sex Med 2023; 20:200-204. [PMID: 36763912 DOI: 10.1093/jsxmed/qdac030] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Revised: 11/08/2022] [Accepted: 11/10/2022] [Indexed: 01/13/2023]
Abstract
BACKGROUND In the original clinical trials evaluating intralesional collagenase Clostridium histolyticum for Peyronie disease (PD), treatment protocols were limited to 8 injections. AIM We sought to describe our single-center experience with the use of multiple rounds (>8 injections) of intralesional collagenase in patients with PD. METHODS We conducted a retrospective analysis of all patients with PD receiving intralesional collagenase injections at our institution from October 2015 through December 2020. Some patients who completed 1 round of treatment elected to undergo additional rounds (16 or 24 injections) based on persistent curvature and presence of penile plaque. Clinical improvement was defined as a 20% reduction in penile curvature from the start of a given round of treatment to the end of that round of treatment. We measured erect penile curvature before and after each round and collected demographics, medical and surgical history, curvature outcomes, and treatment-related adverse events. OUTCOME The primary outcome was the reduction in penile curvature after multiple rounds of treatment with intralesional collagenase injections in patients with PD. RESULTS A total of 330 patients underwent intralesional collagenase injections for PD, of whom 229 completed at least 8 injections and underwent pre- and posttreatment erect penile goniometry. An overall 42.8% (98/229), 38.6% (22/57), and 12.5% (1/8) of patients achieved clinical improvement after 1 round of therapy (8 injections), 2 rounds (16 injections), and 3 rounds (24 injections), respectively. Mean degree and mean percentage improvement of penile curvature for the start and end of each round of treatment were 8.3° and 16.4% (after 1 round), 7.2° and 16.8% (after 2 rounds), and 3.3° and 8.1% (after 3 rounds). Bruising was the most common complication, with an incidence of at least 50% in each round. CLINICAL IMPLICATIONS Knowledge of patient responses to multiple rounds of intralesional collagenase injections may help guide physicians in management and counseling of patients regarding PD treatment options. STRENGTHS AND LIMITATIONS This is the first study to evaluate multiple rounds (>8 injections) of intralesional collagenase for PD. Limitations include retrospective analysis and smaller sample size among patients undergoing 3 rounds (24 injections). CONCLUSION For patients who did not achieve clinical improvement after 1 round of treatment, an additional round may be beneficial. However, no real improvement was observed for patients undergoing a third round.

Cannabis and male sexual health: contemporary qualitative review and insight into perspectives of young men on the internet. Sex Med Rev 2023; 11:139-150. [PMID: 36763944 DOI: 10.1093/sxmrev/qeac010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Revised: 12/02/2022] [Accepted: 12/09/2022] [Indexed: 01/20/2023]
Abstract
INTRODUCTION Cannabis use is increasing across the United States, yet its short- and long-term effects on sexual function remain controversial. Currently, there is a paucity of studies exploring the relationship between cannabis and men's health. OBJECTIVES To summarize the available literature on cannabis and men's health and provide insight into lay perceptions of this topic. METHODS We performed a qualitative PubMed review of the existing literature on cannabis and men's health according to the PRISMA guidelines. Separately, we analyzed relevant themes in online men's health forums. We utilized a Google cloud-based platform (BigQuery) to extract relevant posts from 5 men's health Reddit forums from August 2018 to August 2019. We conducted a qualitative thematic analysis of the posts and quantitatively analyzed them using natural language processing and a meaning extraction method with principal component analysis. RESULTS Our literature review revealed a mix of animal and human studies demonstrating the negative effects of cannabis on semen parameters and varying effects on erectile function and hormone levels. In our analysis of 372 686 Reddit posts, 1190 (0.3%) included relevant discussion on cannabis and men's health. An overall 272 posts were manually analyzed, showing that online discussions revolve around seeking answers and sharing the effects of cannabis on various aspects of sexual health and quality of life, often with conflicting experiences. Quantitative analysis revealed 1 thematic cluster related to cannabis, insecurity, and mental/physical health. CONCLUSIONS There is a limited number of quality human studies investigating the effects of cannabis on men's health. Men online are uncertain about how cannabis affects their sexual health and seek more information. As the prevalence of cannabis use increases, so does the need for research in this area.

Temporal Changes of Clomiphene on Testosterone Levels and Semen Parameters in Subfertile Men. World J Mens Health 2023; 41:198-203. [PMID: 35791301 PMCID: PMC9826904 DOI: 10.5534/wjmh.220010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2022] [Revised: 04/02/2022] [Accepted: 04/08/2022] [Indexed: 01/21/2023] Open
Abstract
PURPOSE Clomiphene citrate (CC) is prescribed off-label in men to improve testosterone and sperm parameters, but the duration of treatment needed to reach maximal benefit remains unclear. Our objective was to examine temporal effects of CC on total testosterone (TT) and semen analysis (SA) using longitudinal follow-up data in treated men. MATERIALS AND METHODS We analyzed an IRB-approved database of men treated with CC (25 mg q.d. or 50 mg q.o.d.) from January 2016 through May 2021. We identified patients with 3, 6, 9, and 12 month follow-up data for TT and 3, 6, and 9 month follow-up SA. Mean absolute changes in TT and sperm concentration compared to baseline were calculated, along with 95% confidence intervals. Men with prior genitourinary procedures or hormone therapy were excluded. Paired t-tests were used to compare TT and sperm concentration at each time point to baseline (alpha=0.05). RESULTS One hundered thirty-four men received CC, mean age 37.7 years (SD 6.7, range 24-52). TT at all follow-ups (3, 6, 9, and 12 months) were available for 25 men, and SA at 3, 6, and 9 months for 26 men. Baseline TT was 358±145 ng/dL and sperm concentration was 13±17.2 M/mL. Significant improvement in TT was identified at 3 months (62.7 ng/dL, 95% CI: 0.49-125.0, p=0.048), additional benefit at 6 months (181.8 ng/dL, 95% CI: 114.1-249.5, p<0.01), and plateau at 9 and 12 months. Improvement in sperm concentration was first observed at 9 months (20.7 M/mL, 95% CI: 10.2-31.2, p<0.01). Semen volume and sperm motility did not change. CONCLUSIONS Duration of treatment with clomiphene may impact testosterone and sperm concentration, and the historical 3 month milestone may be insufficient for clinical and research evaluation. Men taking CC may experience plateau in TT at 6 months and first benefit in sperm concentration at 9 months.

Abstract
INTRODUCTION Due to the increasing prevalence of erectile dysfunction (ED) and pronounced distress for patients, a direct-to-consumer market for shock wave therapy (SWT) has emerged. We sought to evaluate trends in marketing and implementation of SWT as a restorative treatment for ED in large metropolitan areas by investigating cost to patients, provider credentials and treatment protocols. METHODS SWT providers in 8 of the most populous metropolitan areas were identified using Google search. Search queries included: "Shockwave therapy for erectile dysfunction in [city];" "Shockwave therapy for ED in [city];" and "GAINSWave in [city]." All clinics advertising SWT for ED within the boundaries of the selected metropolitan area were included. Using a "secret shopper" methodology, clinics were contacted by telephone with the goal of identifying the pricing, duration and provider administering the treatment. RESULTS Across 8 of the most populous cities in the U.S., 152 clinics offered SWT as a treatment for ED. Comprehensive information was available for 65% of the clinics; 25% of providers offering SWT were urologists while 13% were not physicians. The average price per treatment course was $3,338.28. Treatment duration was highly variable and ranged from 1 to indefinite courses based on individual patient circumstance. CONCLUSIONS SWT, as a restorative therapy for ED, is performed primarily by nonurologists and is not standardized. Direct-to-consumer marketing is used to target distressed men. This study highlights concerning trends in major metropolitan markets, given the substantial financial impact for patients and inconsistent credentials among providers. Further, these findings suggest that patients are frequently seeking care for ED from nonurologists.

3D-printed phantoms to quantify accuracy and variability of goniometric and volumetric assessment of Peyronie's disease deformities. Int J Impot Res 2021; 34:786-789. [PMID: 34743194 DOI: 10.1038/s41443-021-00486-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 10/10/2021] [Accepted: 10/15/2021] [Indexed: 11/09/2022]
Abstract
Characterization of Peyronie's disease (PD) involves manual goniometry and penile length measurement. These techniques neglect volume loss or hourglass deformities. Inter-provider variability complicates accuracy. Using 3D-printed models, we aimed to evaluate measurement accuracy and variability and establish computational assessment workflows. Five digital phantoms were created: 13.0 cm cylinder, 13.0 cm hourglass cylinder, 15.0 cm cylinder with 40° angulation, 12.0 cm straight penis, and 12.9 cm PD penis with 68° angulation and hourglass. Lengths, volumes, and angles were determined computationally. Each phantom was 3D-printed. Ten urology providers determined lengths, angles, and volumes with measuring tape, goniometer, and volume calculator. Provider versus computational measurements were compared to determine accuracy using t-tests or Wilcoxon rank-sum tests. No significant differences were observed between manual assessment of length of penile models and designed length in penile models. Average curvature angles from providers for bent cylinder and PD phantoms were 38.3° ± 3.9° (p = 0.25) and 57.5° ± 7.2° (p = 0.006), respectively. When assessing for volume, hourglass cylinder and bent cylinder showed significant differences between designed volume and provider averages. All assessments of length, angle, and volume showed significant provider variability. Our results suggest manual measurements suffer from inaccuracy and variability. Computational workflows are useful for improved accuracy and volume assessment.

Activation of the iNOS/NO/cGMP pathway by Revactin® in human corporal smooth muscle cells. Transl Androl Urol 2021; 10:2889-2898.

Abstract
Background The combination of the nutraceuticals, Paullinia cupana, ginger rhizome, muira puama, and the amino acid L-citrulline (COMP-4) has been shown to stimulate the production of inducible nitric oxide synthase (iNOS), nitric oxide (NO), and cGMP in rat corpora cavernosa smooth muscle cells (CSMC). When administered to middle-aged rats, long-term treatment with COMP-4 resulted in both an increase in the number of CSMC and an improvement in erectile function. We, therefore, aimed to determine whether a commercial formulation of COMP-4, Revactin®, could have a similar stimulatory effect on human CSMC. Methods Primary human CSMC cultures (HCSMC) were grown and incubated with Revactin® for up to 24 hours. cGMP generation and nitrite formation were determined by ELISA and Griess reaction, respectively. IBMX (1 mM), sildenafil (0.4 mM), and L-NIL (4 µM) were utilized as modulators of the NO-cGMP pathway. iNOS, endothelial NOS (eNOS), and neuronal NOS (nNOS) expressions were determined by Western blot. Results Revactin® up-regulated both nitrite formation and cGMP expression, achieving the highest expression at 24 hours in the HCSMC. These effects were completely blocked by L-NIL. Revactin® up-regulated iNOS expression, but not that of eNOS or nNOS. Conclusions The results presented in this study confirmed that Revactin® activated the iNOS-NO-cGMP pathway intracellularly in HCSMC. It still needs to be determined whether the upregulation of this pathway would be an effective approach for counteracting the fibrosis and apoptosis of the corporal smooth muscle cells associated with aging.

Abstract
Background: Pandemic restrictions have changed how patients approach symptomatic kidney stones. We used a mixed-methods digital ethnographic approach to evaluate social media discussions about patient concerns and preferences for urolithiasis care during the COVID-19 pandemic. Materials and Methods: We retrospectively analyzed kidney stone-related discussions on a large social media platform using qualitative analysis and natural language processing-based sentiment analysis. Posts were mined for demographic details, treatments pursued, and health care encounters. Pre-COVID-19 (January 1, 2020–February 29, 2020) and COVID-19 (March 1, 2020–June 1, 2020) posts were extracted from the popular online Reddit discussion board, “r/KidneyStones,” which is dedicated to discussions related to urolithiasis. Results: We extracted n = 649 posts (250 pre-COVID-19, 399 COVID-19); 150 from each cohort underwent thematic analysis and data extraction. Quantitative sentiment analysis was performed on 418 posts (179 pre-COVID-19, 239 COVID-19) that described stone-related decision making before intervention. Notable discussion themes during COVID-19 focused on barriers to care and concerns about stone management. Discussants exhibited more negative and anxious tones during COVID-19, based on sentiment analysis (p < 0.01). Patient preferences shifted away from in-person visits and procedures (p < 0.001). Mean reported stone size among those visiting emergency room (ER) increased from 5.1 to 10.5 mm (p < 0.001). The proportion of discussants preferring conservative management with stones ≥10 mm increased (12.5% pre-COVID-19 vs 26% during COVID-19, p = 0.002). Opioid mentions increased from 9% to 27% of posts (p < 0.001) and were most associated with conservative management discussions. Conclusions: Online discussion forums provide contemporaneous insight into patients' experiences during a time when traditional patient-centered research methodologies are limited due to social distancing. During the pandemic, patients with symptomatic kidney stones expressed anxiety regarding outpatient encounters and reluctance toward procedural intervention. Patients opted instead for at-home conservative treatment beyond clinical guidelines and reserved ER visits for larger stones, potentially causing self-harm. Opioid discussions proliferated, an alarming consequence of the pandemic.

Initial gonadotropin levels and sperm parameters differentiate the response to clomiphene citrate in subfertile men. Transl Androl Urol 2021; 11:116-123.

Abstract
Background Efficacy of clomiphene citrate (CC) in the treatment of male subfertility remains unclear, with inconsistent results in the literature and limited guidance from professional organizations. We sought to stratify the response to clomiphene in men based on their initial gonadotropins and semen parameters. Methods We conducted a retrospective analysis of 234 patients from an academic center who took CC for subfertility. Patients with pre-treatment and 3 months follow-up total testosterone (TT) and semen analyses were included. Patients with previous hormone therapy, genitourinary surgery, prior success in conceiving pregnancy, or only one semen analysis were excluded. Primary outcomes were magnitudes of improvement in TT and semen parameters at 3 months. Student’s t-test (alpha =0.05) was used for univariate analyses; multivariable linear regression was used for multivariate analysis. Results One hundred and thirty-seven patients met inclusion criteria. Thirty-four percent of patients experienced improvement in sperm concentration after 3 months of CC treatment, 13% decreased, and 53% showed no change. Using a pre-treatment TT cutoff of 300 ng/dL and gonadotropin thresholds of 7 miU/mL, initial TT did not affect magnitude of improvement in semen parameters, while lower initial gonadotropins showed statistical improvement across all outcomes. Multivariate analysis showed pre-treatment follicle stimulating hormone (FSH) was inversely correlated with improvement in TT [odds ratio (OR): 2.64e-05, 95% confidence interval (CI): 1.32e-09 to 5.28e-01, P=0.04] and sperm concentration (OR: 0.22, 95% CI: 5.70e-02 to 8.48e-01, P=0.03). We also provide initial gonadotropin cutoffs that suggest statistical benefit from CC use. Conclusions Men with lower gonadotropin levels may expect greater degree of improvement in both hormone and semen parameters with use of CC. Men with azoospermia do not benefit based on semen analyses alone. Degree of non-azoospermia does not affect magnitude of improvement. CC had decreasing efficacy at higher initial gonadotropin levels. These data may provide guidance in stratifying and counseling men for CC treatment.

Abstract
Purpose of Review Focusing on studies published within the last decade, we review the literature on the seminal microbiome and male factor infertility. We highlight potential mechanisms by which microbes may impact fertility and underscore key limitations and clinical implications of these studies. Recent Findings The seminal microbiome encompasses a metabolically and phylogenetically diverse group of microorganisms. Lactobacillus was consistently associated with normal semen analysis parameters and fertility; Anaerococcus was negatively associated with semen quality. These microbes may participate in a complex cross-talk with the host immune system, thereby modulating local and perhaps systemic inflammatory responses, impacting semen quality. Summary Research investigating the intersection between the seminal microbiome and male fertility is still in its infancy. Recent investigations have been exclusively cross-sectional, correlational studies, limiting the clinical applicability of published research. Prospective studies with more sophisticated methodologies are necessary.

Abstract
OBJECTIVE To determine comorbidities in young men with erectile dysfunction (ED) who are increasingly targeted by direct-to-consumer (DTC) internet platforms that sell phosphodiesterase-5 (PDE-5) inhibitors without comprehensive clinical evaluation; and, further, to characterize the portrayal of DTC platforms by popular news media. METHODS We retrospectively reviewed all men age ≤40 evaluated for ED at an andrology clinic during January 2016-March 2019 to obtain demographics, exam and lab findings, and treatments. Five news sources were analyzed during the study period to characterize whether articles about DTC platforms were positive, critical, or balanced/neutral. RESULTS We identified 388 patients, with age 29.5 ± 5.0 years, 15% rate of obesity, 20% prediabetes or diabetes, 54% dyslipidemia, and 20% hypogonadism. Serum lab findings associated with subfertility were found in 11%. Semen analysis was conducted in 64 men, of whom 40% were abnormal. Varicoceles were found in 35%. PDE-5 inhibitor was prescribed to 328 men (88%). Off-label empiric therapies included clomiphene (32.9%) or aromatase inhibitor (12.1%). Testosterone replacement was initiated in 9.7%. Analysis of news coverage revealed 18 articles, of which 61% portrayed DTC platforms exclusively in a positive light. CONCLUSION Office consultation identified young men with significant comorbidities that would be missed by DTC platforms, which employ only questionnaires for health screening. DTC platforms present themselves as medical authorities without following AUA Guidelines, yet garner mostly positive press coverage. Patients engaging these platforms may falsely believe they are receiving adequate medical assessment. Urologists may do well to incorporate telemedicine to enfranchise young men with evidence-based evaluation.

Abstract
Streaming video has emerged as a dominant content-delivery medium for healthcare information, with over 30 million visitors daily to the YouTube platform alone. Videos related to men’s health have proliferated, but content produced by trained health care providers remains scarce. We evaluated educational YouTube streaming videos created in collaboration with a large, university-based health system focused on male factor infertility, men’s health, and Peyronie’s disease, uploaded during 2016–2018. All videos featured a board-certified urologist with fellowship training in andrology. Using YouTube’s native analytics tools, we extracted data on views, engagement, and geographic reach through 8/2019. We obtained data for streaming videos on male infertility (n=3), general men’s health (n=2), and Peyronie’s disease (n=1). Video length ranged from 29 to 51 min, with a mean video duration of 39 min 41 sec. Actual mean watch time by viewers ranged from 3:45 to 8:30. The total view count was 646,684, with a watch time of nearly 3 million mins, reaching viewers in 47 countries. Fifty-three percent of watch time was on a mobile device and 33% on a personal computer. As patients increasingly turn to the internet for health information, health systems and physicians may wish to leverage high impact social media platforms such as YouTube to share evidence-based content. This study highlights the impressive reach a health system-sponsored video intervention using YouTube can have in sharing accurate video content related to a diverse range of men’s health topics. This is the first health systems-based streaming-video intervention to leverage the video streaming and social media platform YouTube, to facilitate sharing reputable, high quality, and evidence-based men’s health content.

Abstract
Purpose Infertile couples increasingly turn to the internet for medical guidance. The aims of this study were: (1) to identify popular male infertility content on social media, and (2) to assess the accuracy and quality of this content. We hypothesized that inaccurate/misleading information proliferates online. Materials and Methods We used the analytics module BuzzSumo to identify article links that were most shared on Facebook, Pinterest, Reddit, and Twitter related to male infertility during September 2018 to August 2019. We excluded articles with <100 engagements, defined as “likes,” “comments,” and “shares.” Two researchers graded content as accurate, misleading, or inaccurate by comparing content to references cited and contemporary research. Inter-rater reliability was determined with Cohen's κ. Binary logistic regression was performed to compare user engagement with accurate versus inaccurate/misleading articles. Results Fifty-two unique article links were identified, with 421,004 total engagements. Thirty-four articles referenced 15 scientific studies; no reference was available for 18 links. Fifty-six percent of articles were accurate and 44% misleading/inaccurate (κ=0.743). No significant difference was found in total engagement between accurate vs. misleading/inaccurate links (p=0.805). Twenty-four percent of engagements referenced studies using non-human models, and 26% of studies had sample sizes <100. Conclusions Social media platforms foster engagement with male infertility information. However, sensationalism predominates, as patients are highly likely to encounter misleading/inaccurate information, articles that overstate implications of animal research, and conclusions made based on limited sample sizes. Urologists should consider adding social media to their armamentarium to stave off misinformation and engage proactively with patients.

Abstract
Men’s health is a unique field that requires a multi-disciplinary approach to appropriately treat the full spectrum of men’s health needs. Given that interest in men’s health is relatively new, the definition of a men’s health clinic continues to evolve. Originally conceived as testosterone replacement centers, men’s health clinics are increasingly understood to encompass male endocrine, surgical, urologic, physical performance, and psychological issues. As interest in men’s health continues to grow, it is important to focus on the field’s future, including pharmacies, telemedicine, and the diffusion of healthcare.

Abstract
Inflatable penile prosthesis (IPP) is an effective treatment for erectile dysfunction refractory to nonsurgical management. The infrapubic approach for IPP placement is less frequently employed than the penoscrotal approach, with only about 25% of IPPs placed via this method. Underutilization of the infrapubic method may be due to fear of injuring the penile dorsal neurovascular bundle, perceived difficulties of scrotal pump placement through a distant location, or insufficient distal corporal exposure. However, this approach appears to result in favorable operative times, faster time to device activation, equivalent postoperative satisfaction and quality of life, and similar complication rates. We provide a contemporary review of literature published before May 2019 regarding the infrapubic approach for IPP placement, technical considerations, and postoperative expectations.

Abstract
A variety of surgical options exists for sperm retrieval in the setting of obstructive azoospermia (OA). With appropriate preparation, the majority of these techniques can safely be performed in the office with local anesthesia and with or without monitored anesthesia care (MAC). The available techniques include percutaneous options such as percutaneous epididymal sperm aspiration (PESA) and testicular sperm aspiration (TESA), as well as open techniques that include testicular sperm extraction (TESE) and microsurgical epididymal sperm aspiration (MESA). In addition to providing a step-by-step description of each available approach, we introduce and describe a new technique for sperm retrieval for OA called minimally invasive epididymal sperm aspiration (MIESA). The MIESA utilizes a tiny keyhole incision, and the epididymis is exposed without testicular delivery. Epididymal aspiration is performed in the style of MESA, except using loupe magnification rather than an operating microscope. MIESA is a safe, office-based procedure in which millions of motile sperm can be retrieved for cryopreservation. While we prefer the MIESA technique for OA, there remain distinct advantages of each open and percutaneous approach. In the current era of assisted reproductive technology, sperm retrieval rates for OA should approach 100% regardless of the technique. This reference provides a roadmap for both advanced and novice male reproductive surgeons to guide them through every stage of sperm retrieval for OA, including preoperative evaluation, patient selection, procedural techniques, and complications. With the incredible advances in in vitro fertilization (IVF), combined with innovative surgical treatment for male factor infertility in recent years, OA is no longer a barrier for men to become biologic fathers.

Abstract
Estradiol, normally considered a female hormone, appears to play a significant role in men in a variety of physiologic functions, such as bone metabolism, cardiovascular health, and testicular function. As such, estradiol has been targeted by male reproductive and sexual medicine specialists to help treat conditions such as infertility and hypogonadism. The compounds that modulate estradiol levels in these clinical conditions are referred to as selective estrogen receptor modulators (SERMs) and aromatase inhibitors (AIs). In a certain subset of infertile men, particularly those with hypogonadism, or those who have a low serum testosterone to estradiol ratio, there is some evidence suggesting that SERMs and AIs can reverse the low serum testosterone levels or the testosterone to estradiol imbalance and occasionally improve any associated infertile or subfertile state. This review focuses on the role these SERMs and AIs play in the aforementioned reproductive conditions.

Abstract
In August 2015, an expert colloquium commissioned by the Sexual Medicine Society of North America (SMSNA) convened in Washington, DC, to discuss the common clinical scenario of men who present with low testosterone (T) and associated signs and symptoms accompanied by low or normal gonadotropin levels. This syndrome is not classical primary (testicular failure) or secondary (pituitary or hypothalamic failure) hypogonadism because it may have elements of both presentations. The panel designated this syndrome adult-onset hypogonadism (AOH) because it occurs commonly in middle-age and older men. The SMSNA is a not-for-profit society established in 1994 to promote, encourage, and support the highest standards of practice, research, education, and ethics in the study of human sexual function and dysfunction. The panel consisted of 17 experts in men's health, sexual medicine, urology, endocrinology, and methodology. Participants declared potential conflicts of interest and were SMSNA members and nonmembers. The panel deliberated regarding a diagnostic process to document signs and symptoms of AOH, the rationale for T therapy, and a monitoring protocol for T-treated patients. The evaluation and management of hypogonadal syndromes have been addressed in recent publications (ie, the Endocrine Society, the American Urological Association, and the International Society for Sexual Medicine). The primary purpose of this document was to support health care professionals in the development of a deeper understanding of AOH, particularly in how it differs from classical primary and secondary hypogonadism, and to provide a conceptual framework to guide its diagnosis, treatment, and follow-up.

Abstract
While we may be comfortable with an allopathic approach to male infertility, we are also responsible for knowledge about lifestyle modifications and holistic, complementary, and alternative therapies that are used by many of our patients. This paper provides an evidence-based review separating fact from fiction for several of these therapies. There is sufficient literature to support weight reduction by diet and exercise, smoking cessation, and alcohol moderation. Supplements that have demonstrated positive effects on male fertility on small randomized controlled trial (RCT) include aescin, coenzyme Q 10 , glutathione, Korean red ginseng, L-carnitine, nigella sativa, omega-3, selenium, a combination of zinc and folate, and the Menevit antioxidant. There is no support for the use of Vitamin C, Vitamin E, or saffron. The data for Chinese herbal medications, acupuncture, mind-body practice, scrotal cooling, and faith-based healing are sparse or inconclusive.

Abstract
INTRODUCTION AND AIM About 3 million men take testosterone in the United States with many reproductive-age men unaware of the negative impact of testosterone supplementation on fertility. Addressing this population, we provide an early report on the use of human chorionic gonadotropin (HCG)-based combination therapy in the treatment of a series of men with likely testosterone-related azoospermia or severe oligospermia. METHODS We retrospectively reviewed charts from two tertiary care infertility clinics to identify men presenting with azoospermia or severe oligospermia (<1 million sperm/mL) while taking exogenous testosterone. All were noted to have been placed on combination therapy, which included 3,000 units HCG subcutaneously every other day supplemented with clomiphene citrate, tamoxifen, anastrozole, or recombinant follicle-stimulating hormone (or combination) according to physician preference. MAIN OUTCOME MEASURE Clinical outcomes, including hormone values, semen analyses, and clinical pregnancies, were tracked. RESULTS Forty-nine men were included in this case series. Return of spermatogenesis for azoospermic men or improved counts for men with severe oligospermia was documented in 47 men (95.9%), with one additional man (2.1%) having a documented pregnancy without follow-up semen analysis. The average time to return of spermatogenesis was 4.6 months with a mean first density of 22.6 million/mL. There was no significant difference in recovery by type of testosterone administered or supplemental therapy. No men stopped HCG or supplemental medications because of adverse events. CONCLUSIONS We here provide an early report of the feasibility of using combination therapy with HCG and supplemental medications in treating men with testosterone-related infertility. Future discussion and studies are needed to further characterize this therapeutic approach and document the presumed improved tolerability and speed of recovery compared with unaided withdrawal of exogenous testosterone.

Nomogram to preoperatively predict the probability of requiring epididymovasostomy during vasectomy reversal. J Urol 2011; 187:215-8. [PMID: 22099990 DOI: 10.1016/j.juro.2011.09.026] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2011] [Indexed: 12/12/2022]
Abstract
PURPOSE Up to 6% of men who undergo vasectomy may later undergo vasectomy reversal. Most men require vasovasostomy but a smaller subset requires epididymovasostomy. Outcomes of epididymovasostomy depend highly on specialized training in microsurgery and, if predicted preoperatively, might warrant referral to a specialist in this field. We created a nomogram based on preoperative patient characteristics to better predict the need for epididymovasostomy. MATERIALS AND METHODS We evaluated patients who underwent primary vasectomy reversal during a 5-year period. Preoperative and intraoperative patient data were collected in a prospectively maintained database. We evaluated the ability of age, years since vasectomy, vasectomy site, epididymal fullness and granuloma presence or absence to preoperatively predict the need for epididymovasostomy in a given patient. The step-down method was used to create a parsimonious model, on which a nomogram was created and assessed for predictive accuracy. RESULTS Included in the study were 271 patients with a mean age of 42 years. Patient age was not positively associated with epididymovasostomy. Mean time from vasectomy to reversal was 9.7 years. Time to reversal and a sperm granuloma were selected as important predictors of epididymovasostomy in the final parsimonious model. The nomogram achieved a bias corrected concordance index of 0.74 and it was well calibrated. CONCLUSIONS Epididymovasostomy can be preoperatively predicted based on years since vasectomy and a granuloma on physical examination. Urologists can use this nomogram to better inform patients of the potential need for epididymovasostomy and whether specialist referral is needed.

Abstract
Patients in Goalando were likely infected by direct contact with fruit bats or their secretions, rather than through contact with an intermediate host. Nipah virus (NiV) is a paramyxovirus that causes severe encephalitis in humans. During January 2004, twelve patients with NiV encephalitis (NiVE) were identified in west-central Bangladesh. A case–control study was conducted to identify factors associated with NiV infection. NiVE patients from the outbreak were enrolled in a matched case-control study. Exact odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by using a matched analysis. Climbing trees (83% of cases vs. 51% of controls, OR 8.2, 95% CI 1.25–∞) and contact with another NiVE patient (67% of cases vs. 9% of controls, OR 21.4, 95% CI 2.78–966.1) were associated with infection. We did not identify an increased risk for NiV infection among persons who had contact with a potential intermediate host. Although we cannot rule out person-to-person transmission, case-patients were likely infected from contact with fruit bats or their secretions.

Abstract
The replication of four antigenic types of avian reovirus in various subpopulations of avian leukocytes was investigated. Virus replication was detected in infected cells by immunofluorescence using a monoclonal antibody against a virion protein and by electron microscopy. All four types of reovirus replicated in cultured, adherent mononuclear cells of both bone marrow and peripheral blood origin causing lysis and fusion of the infected cells. Some evidence of strain variation in the capacity of avian reoviruses to replicate in these cells was detected. Avian reovirus did not replicate in heterophils or thrombocytes of peripheral blood origin or in bursa or thymus-derived lymphocytes.

Abstract
Erectile dysfunction is a disease that affects half of American men aged over 50 years. Many men respond to oral phosphodiesterase inhibitors but many do not. For this reason, many researchers are focusing their efforts on developing novel gene therapies for the treatment of erectile dysfunction. Aided by the meticulous characterization of the molecular cascades involved in the physiology of erection, several groups around the world are studying gene therapies in animal models, and one in a human clinical trial. Here we provide a review of the pathophysiology of erectile dysfunction and how it relates to the molecular targets of novel gene therapeutics. The field of gene therapy for the treatment of erectile dysfunction is continually growing, and this decade will likely see exciting results as the expansion from animal models to human clinical trials continues.
