Self-Reported Race/Ethnicity Is Not Associated with Abnormal Semen Parameters after Accounting for Body Mass Index and Socioeconomic Status.

PURPOSE: We evaluated whether consideration of body mass index (BMI) and socioeconomic status alters the reported association between race/ethnicity and abnormal semen parameters. MATERIALS AND METHODS: We conducted a retrospective review of all men who underwent semen analysis (SA) for fertility evaluation at an integrated academic health care system from 2002 to 2021. Men were excluded if they had a diagnosis of Klinefelter's syndrome, history of varicocele, prior testicular surgery, prior history of chemotherapy or radiation for cancer, or prior testosterone-modulating medication use. Chi-square and Kruskal-Wallis tests were used to analyze categorical and continuous variables across self-reported racial groups, respectively. Logistic regression was used to evaluate the association between race and abnormal semen parameters according to WHO 2010 criteria, controlling for potential confounders. RESULTS: Among 2,750 men meeting inclusion criteria, 2,037 (74.1%) identified as White Non-Hispanic, 207 (7.5%) as Black Non-Hispanic, 245 (8.9%) as Hispanic and 261 (9.5%) as Asian. Median age was 35 years (IQR 32-40). Black men had an older median age (37 years, IQR 33-42, p=0.002) than other groups at the time of index SA. While Black men had higher odds of abnormal sperm concentration (OR 1.46, 95% CI 1.06-2.02, p=0.02) and abnormal total motile sperm count (OR 1.65, 95% CI 1.21-2.25, p=0.001) compared to other men after adjusting for age alone, the association of race with abnormal semen parameters was rendered insignificant with the progressive inclusion of BMI, insurance status and neighborhood income as covariates. CONCLUSIONS: In men undergoing SA for fertility evaluation, we did not see evidence of an association between race/ethnicity and abnormal semen parameters after controlling for BMI, insurance status and neighborhood income.

The adverse impact of COVID-19 on men's health.

PURPOSE OF REVIEW: The COVID-19 pandemic has led to devastating health outcomes across the world. Initially thought to primarily affect the respiratory system, there is now clear and abundant evidence that COVID-19 can impact upon the male genitourinary system and overall men's health. In this review article, we explore the potential mechanisms by which COVID-19 specifically affects men and we review the literature examining the adverse effects of the disease on men's health. RECENT FINDINGS: Studies suggest that men are at higher risk for severe COVID-19 infection and death. COVID-19 infection has a negative impact on men's health including worsening semen parameters, potentially lower testosterone levels, and an increased risk of erectile dysfunction. SUMMARY: COVID-19 is a highly pathogenic virus that exerts adverse effects upon the male genitourinary system in myriad ways. The COVID-19 infection can impact serum testosterone, fertility, sexual function, and mental health. Fortunately, the COVID-19 vaccine is safe and effective in preventing COVID-19 infection and many of these sequelae.

Urological Cancers and Kidney Transplantation: a Literature Review.

PURPOSE OF REVIEW: The aim of this review is to provide an overview of epidemiology, risk factors, and treatment of urological malignancies in renal transplant recipients (RTR). RECENT FINDINGS: Although optimal immunosuppressive therapy and cancer management in these patients remain controversial, adherence to general guidelines is recommended. Kidney transplantation is recognized as the standard of care for the treatment of end-stage renal disease (ESRD) as it offers prolonged survival and better quality of life. In the last decades, survival of RTRs has increased as a result of improved immunosuppressive therapy; nonetheless, the risk of developing cancer is higher among RTRs compared to the general population. Urological malignancies are the second most common after hematological cancer and often have more aggressive behavior and poor prognosis.

Analysis of the growing public interest in selective androgen receptor modulators.

To characterise trends and interest in selective androgen receptor modulators (SARMs). SARMs are androgen receptor ligands that bind androgen receptors selectively. SARMs have anabolic effects on muscle and bone and were originally synthesised for treatment of muscle wasting conditions, osteoporosis and breast cancer. To date, no SARM has been clinically approved and little is known about their beneficial effects and other adverse effects on users. We examined Google Trend searches of SARMs. Using Google Trends, we analysed how interest in SARMs has evolved over the last 15 years and compared it to trends in testosterone. Comparing 'TRT', 'SARMs' and 'Low Testosterone' together, we see low search interest in SARMs compared to TRT until February 2018, when the interest in both SARMs and TRT terms appear to be the same. Since February 2018, search interest for SARMs has surpassed search interest for both 'TRT' and 'Low Testosterone'. Trends for SARMs demonstrate a continuous increase over the years which has to date surpassed interest for both 'TRT' and 'low testosterone'. The rising interest in SARMs is concerning as the adverse effects of its usage, including its potential effects on fertility, have not been explored. Further investigation is necessary.

Telemedicine Usage Among Urologists During the COVID-19 Pandemic: Cross-Sectional Study.

BACKGROUND: Prior to the COVID-19 pandemic, urology was one of the specialties with the lowest rates of telemedicine and videoconferencing use. Common barriers to the implementation of telemedicine included a lack of technological literacy, concerns with reimbursement, and resistance to changes in the workplace. In response to the COVID-19 pandemic declared in March 2020, the delivery of urological services globally has quickly shifted to telemedicine to account for the mass clinical, procedural, and operative cancellations, inadequate personal protective equipment, and shortage of personnel. OBJECTIVE: The aim of this study was to investigate current telemedicine usage by urologists, urologists' perceptions on the necessity of in-person clinic appointments, the usability of telemedicine, and the current barriers to its implementation. METHODS: We conducted a global, cross-sectional, web-based survey to investigate the use of telemedicine before and after the COVID-19 pandemic. Urologists' perceived usability of telemedicine was assessed using a modified Delphi approach to create questions based on a modified version of the validated Telehealth Usability Questionnaire (TUQ). For the purposes of this study, telemedicine was defined as video calls only. RESULTS: A total of 620 urologists from 58 different countries and 6 continents participated in the survey. Prior to COVID-19, 15.8% (n=98) of urologists surveyed were using telemedicine in their clinical practices; during the pandemic, that proportion increased to 46.1% (n=283). Of the urologists without telemedicine experience, interest in telemedicine usage increased from 43.7% (n=139) to 80.8% (n=257) during the COVID-19 pandemic. Among urologists that used telemedicine during the pandemic, 80.9% (n=244) were interested in continuing to use it in their practice. The three most commonly used platforms were Zoom, Doxy.me, and Epic, and the top three barriers to implementing telemedicine were patients' lack of technological comprehension, patients' lack of access to the required technology, and reimbursement concerns. CONCLUSIONS: This is the first study to quantify the use, usability, and pervading interest in telemedicine among urologists during the COVID-19 pandemic. In the face of this pandemic, urologists' usage of telemedicine nearly tripled, demonstrating their ability to adopt and adapt telemedicine into their practices, but barriers involving the technology itself are still preventing many from utilizing it despite increasing interest.

Evaluation of Indicators of Female Sexual Dysfunction in Adult Entertainers.

INTRODUCTION: Female sexual dysfunction (FSD) incorporates a wide range of sexual issues within the female population; however, it has not been evaluated among female adult entertainers. AIM: To evaluate the prevalence of FSD in women working in the adult entertainment industry. METHODS: A 53-question online survey was distributed to female adult entertainers via e-mail through collaboration with the Free Speech Coalition, the North American Trade Association of the Adult Industry. Surveys were sent by the Free Speech Coalition to those within the Performer Availability Screening Services database who met the criteria of having biological vaginas and having experience as adult entertainers. The surveys were answered anonymously. Statistical analysis was performed with Stata/IC 15.1. MAIN OUTCOME MEASURES: The survey acquired baseline characteristics, use of contraceptives, sexual activity, work vs home sexual satisfaction, and orgasm, in addition to evaluation of female sexual function using the Female Sexual Function Index survey, with a total score <26.55 indicative of FSD. RESULTS: Of the 147 respondents, 96 (65%) met inclusion criteria of adequately completing the survey, having a biological vagina, and working in the adult entertainment industry. The mean age was 34.1 ± 10.3 years (range 20-66). The average Female Sexual Function Index score was 28.7 ± 5.6, and 24.0% (23 of 96) of entertainers had scores indicative of FSD. Overall, women found their personal sex lives more satisfying when compared with their professional sex lives (3.99 ± 1.40 vs 3.08 ± 1.52, P < .01). When comparing women with FSD to those without FSD, women with FSD had less sexual satisfaction at home (2.8 ± 1.7 vs 4.4 ± 1.0, P < .01), fewer overall sexual events (7.0 ± 6.7 FSD vs 12.9 ± 10.0 non-FSD, P < .01), and fewer satisfying sexual events overall (3.3 ± 4.2 vs 10.7 ± 8.7, P < .01). CLINICAL IMPLICATIONS: FSD is prevalent among all women, including those within the adult entertainment industry, and must be addressed during patient interactions. STRENGTH & LIMITATION: This is the first study to evaluate the novel group of female adult entertainers. Despite this novel population, the study size is rather small and is susceptible to response bias. CONCLUSION: FSD appeared to be less prevalent among female adult entertainers than rates commonly quoted for the general population and was more often seen in the women with less satisfying personal sex lives.

Partial nephrectomy in a patient with dwarfism.

We describe the case of a 50-year-old male with achondroplastic dwarfism who presents with a renal mass in his left kidney concerning for renal cell carcinoma. The patient successfully underwent a robotic partial nephrectomy, which revealed a T1a renal cell carcinoma. The tumor was excised successfully without any intraoperative complications demonstrating that a robotic partial nephrectomy is technically both safe and effective in patients with achondroplastic dwarfism.

Prevalence of infertility and barriers to family building among male physicians.

BACKGROUND: Fertility declines with increasing age and physicians often delay childbearing beyond prime reproductive years for the sake of medical training. However, the risks of infertility in male physicians compared to the general population remain poorly studied. OBJECTIVES: To characterize rates of infertility among male physicians and identify barriers in access to fertility care and family building. MATERIALS & METHODS: Between June 2022 and December 2022, male physicians were invited to complete a questionnaire regarding fertility and family building. Surveys were disseminated electronically via social media and professional medical societies using Qualtrics (Provo, UT). RESULTS: Two hundred thirty-five responses were included in the final analysis. The mean age of respondents was 36.3 ± 7.4 years. Of 151 respondents with children or currently attempting to have children, 66 (43.7%) delayed family building due to their medical training or career. The most influential factors affecting timing of children were lack of flexibility in schedule, lack of time, stress, and financial strain. Forty-three (18.3.%) respondents had seen a doctor for fertility evaluation; an additional 12 (5.1%) said they considered doing so but did not, mostly due to being too busy. Sixty (25.5%) had undergone semen testing in the past. Thirty-one (13.2%) reported a diagnosis of fertility issues in either themselves or their partner. Twenty-seven (11.5%) endorsed either them or their partner having undergone assistive reproductive technologies or other procedures for infertility. DISCUSSION: A significant proportion of male physicians delayed building their family or seeking fertility evaluation due to their medical career. Around 23.4% of male physicians have either seen or considered seeing a physician for fertility evaluation, suggesting a high prevalence of infertility in this cohort. CONCLUSION: Our results indicate a need for interventions to support family building and fertility evaluation and treatment among male physicians.

Prospective Patient Preferences for Humor in Urologists Treating Erectile Dysfunction: A Survey Study.

INTRODUCTION: Men seeking treatment for sexual dysfunction can experience embarrassment as a result of stigma. This research manuscript presents the findings of a survey conducted to investigate the influence of humor on prospective patients' preferences when selecting a specialist to address erectile dysfunction (ED). METHODS: The respondents were presented with five pairs of mock urology business cards: one professional and one humorous. A questionnaire was designed and distributed via an online survey platform. Descriptive statistics and Fisher's exact test were performed using the Statistical Package for Social Sciences (SPSS) software version 29 (IBM SPSS Statistics, Armonk, NY) to evaluate age and race associations with card preference. RESULTS: Among the 997 participants, an average of 66.1% (a median of 71.2%) preferred professional cards. Humorous card selection rates ranged from 5.2% to 38.4% compared to 54.0% to 78.1% for professional cards. A statistically significant relationship between age and professional card choice existed in all except the fifth set of cards (p = 0.001, 0.001, 0.001, 0.001, and 0.054). The relationship between race or ethnicity and business card preference was not reported due to an imbalance in demographics, with most participants identifying as Caucasian. DISCUSSION: A humor-centric approach may not resonate with all individuals seeking treatment for sensitive conditions such as ED. Limitations include the subjectivity of humor, the use of an online survey platform, and the hypothetical nature of this study. Real patients experiencing ED may face stigma and respond to humor differently. CONCLUSION: This study provides insights into patient preference for professionalism over humor from their urologist but leaves room for the exploration of humor in medical contexts. Future studies could examine the impacts of humor on patient choices in real-world healthcare settings.

Beyond the prescription: trends and challenges in erectile dysfunction medications among young adult men.

We sought to assess erectile dysfunction (ED) medication use among males aged 18-40. Between June and July 2023, a cross-sectional survey on Qualtrics (Provo, UT) was disseminated via Research Match. Among 210 respondents, ED prevalence was 57.1% with 39.0% reporting prior ED medication use. Black or African American race (OR = 3.54, p < 0.001), Hispanic or Latino ethnicity (OR = 3.32, p = 0.01), and Medicare or Medicaid insurance status (OR = 6.07, p < 0.001) were associated with increased medication utilization. Income >$200,000 was associated with decreased medication usage (OR 0.23, p = 0.04). ED severity significantly correlated with higher medication usage. Primary care providers were the most common source of acquisition (47.6%), followed by online direct to consumer (DTC) platforms (31.7%) and personal connections (19.5%). Privacy (n = 51, 62.2%) and cost (n = 45, 54.9%) were key considerations in obtaining medications. Despite 73.2% of individuals receiving counseling regarding risks/benefits and 84.1% receiving instructions for proper use, only 28.0% correctly identified essential aspects of proper/appropriate use. Overall, we found a high ED prevalence and medication utilization rate. The preference for privacy in procuring medications suggests ongoing stigma around men's sexual health. Despite extensive counseling, a significant knowledge gap remains indicating a pressing need for enhanced patient education.

Prevalence of sexual dysfunction and pursuit of sexual medicine evaluation among male physicians-a survey.

We sought to characterize the prevalence of sexual dysfunction and barriers to treatment among male physicians. Between June and December 2022, male physicians were invited to complete a questionnaire regarding sexual function. Surveys were disseminated electronically via social media and professional medical societies using Qualtrics (Provo, UT). In totla, 235 responses were included in the final analysis. The mean age of respondents was 36.3 ± 7.4 years (range 23-72). 27 (11.5%) reported having seen a doctor for sexual health. Of these 27, 40.7% saw a physician for erectile dysfunction, 29.6% for low libido, 22.2% for premature ejaculation, 7.4% for delayed ejaculation, and 33.3% for other concerns. An additional 29 (12.3%) considered establishing care for sexual issues but didn't, mostly due to being too busy. 46 (19.6%) respondents reported having taken medication to improve erectile function. Therefore, in a cohort of young male physicians, 23.8% had seen or considered seeing a doctor for sexual health concerns, and nearly 1 in 5 had taken medication for erectile dysfunction. Male physicians appear to be at higher risk for sexual dysfunction than the general population and face significant and unique barriers in access to care for sexual dysfunction.

Misinformation About Orthopaedic Conditions on Social Media: Analysis of TikTok and Instagram.

Introduction Social media outlets such as TikTok (TT) and Instagram (IG) have surged as a method to disseminate information. More recently, healthcare professionals have targeted this space as a means to provide medical education and advice. With the ever-growing content on these applications, there is significant variability and quality of material available, which can lead to the dissemination of misinformation. This study aims to evaluate the accuracy and popularity of content on common orthopaedic pathology on TT and IG. Methods Content on TT and IG related to six common orthopaedic conditions - achilles tendon tear, ACL tear, meniscus tear, tennis elbow, rotator cuff tear, and ankle sprains - was evaluated between April and June 2022. The top ten posts for the top two associated hashtags for each condition were reviewed. The quality of each post was analyzed using the DISCERN instrument, rating each on a scale of 1 to 5. Each post was characterized by the author's profession (physician, physical therapist, chiropractor, etc.) and content type (educational, testimonial, personal, promotional, and entertainment). Popularity and engagement metrics such as "comments," "likes," and "shares" were also collected. Results There were 165,666,490 views on TT and 9,631,015 views on IG amongst the six common aforementioned orthopaedic conditions. Content created by physicians had less overall engagement (16.1%) compared to content created by non-physicians (83.9%). The quality of content on average was low (mean misinformation index 2.04 ± 1.08 (1-5)1. Physician-created posts in comparison to non-physician posts were significantly more accurate (mean misinformation index score 3.38 ± 1.12 vs 1.89 ± 0.94, p<0.0001). Conclusions Common orthopaedic conditions such as Achilles tendon tears, ACL tears, and meniscus tears are frequently the focus of content posted on TT and IG; however, this information is often not medically accurate. Increased physician engagement may help to rectify this misinformation.

Do Articles Shared by Academic Medicine Social Media Influencers Drive Future Citation Rates?

OBJECTIVE: To assess the role of influential figures within social media (SoMe) in driving future citations. METHODS: All original articles published in the Journal of Urology and European Urology in 2018 were identified. For each article, number of mentions on any SoMe platform, article's Twitter reach, and total citations were collected. Article characteristics such as type of study, article topic, and open access status were identified. Total academic research output was obtained for first and last authors of included articles. Influential SoMe figures were defined as users that tweeted about included articles and had over 2000 followers. For these accounts, we collected total followers, total tweets, engagement statistics, verification status, and academic characteristics such as total citations and total prior publications. The impact of SoMe, article, and academic characteristics on future citations was assessed using panel data regression analysis. RESULTS: We identified 394 articles with 8895 total citations and 460 SoMe influencers. On panel data regression modeling, tweets about a specific article were associated with future citations (0.17 citations per tweet about an article, P < .001). SoMe influencer characteristics were not associated with increased citations (P > .05). The following non-SoMe-associated characteristics were predictive of future citations (P < .001): study type (prospective studies received 12.9 more citations than cross-sectional studies), open access status (4.3 citations more if open access, P < .001), and previously well-published first and last authors. CONCLUSION: While SoMe posts are associated with increased visibility and higher future citation rates, SoMe influencers do not appear to drive these outcomes. Instead, high quality and accessibility were more predictive of future citability.

Compensated Hypospermatogenesis: Elevated Follicle-stimulating Hormone Predicts Decline in Semen Parameters Among Men With Normal Index Semen Analysis.

OBJECTIVE: To determine whether men with elevated follicle-stimulating hormone (FSH) and normal semen analysis (SA) are more likely to experience a decline in semen parameters over time compared to men with normal FSH. METHODS: Men presenting for fertility evaluation between 2002 and 2020 with normal initial SA were dichotomized according to baseline FSH as normal (<7.6 IU/mL) vs elevated (≥7.6 IU/mL). Primary outcomes included the development of abnormal sperm concentration (<15 million/mL) and total motile sperm count <9 million. Secondary outcomes included abnormal sperm motility (<40%), morphology (<4%), and total number of SA abnormalities. RESULTS: The final sample consisted of 858 men; 776 had normal FSH, and 82 had elevated FSH at presentation. Compared to men with normal FSH, men with elevated FSH had lower total motile sperm count (64.1 vs 107.3, P < .001) and higher testosterone levels (339 ng/dL vs 309 ng/dL, P = .03). At each follow-up timepoint, more men with elevated FSH had oligospermia compared to men with normal FSH. Men with elevated FSH were more likely to experience a decline in total motile sperm count below the intrauterine insemination threshold of 9 million and more likely to develop SA abnormalities over time. CONCLUSION: In men presenting for fertility evaluation with normal index SA, elevated FSH was associated with subsequent decline in semen parameters over time. Men with elevated FSH and normal SA, a condition we have termed compensated hypospermatogenesis, represent an at-risk population for whom close follow-up is warranted.

Predictors of Semen Parameters Decline Following the Microsurgical Varicocelectomy.

Objective Varicocele is considered the most common reversible cause of male infertility. However, some men do not clinically improve after surgical repair. We aimed to identify preoperative factors associated with decreased semen parameters and clinical "downgrading" of total motile sperm count (TMSC) following varicocelectomy. Methods We examined men with preoperative laboratory testing and pre- and postoperative semen analyses (SA) who underwent varicocelectomy between 2010 and 2020. Ejaculate volume, sperm motility, sperm concentration, TMSC, and clinical grade of TMSC (in vitro fertilization: <5M sperm, intrauterine insemination: 5-9M sperm, natural pregnancy: >9M sperm) were used to determine postoperative outcomes. Demographic and clinical factors were compared between cohorts. Results Among 101 men who underwent varicocelectomy, 35 (34.7%) had decreased postoperative TMSC with a median follow-up of 6.6 months (interquartile range 3.9-13.6 months). Eleven (10.9%) men experienced TMSC clinical "downgrading" following surgery. Clinical grade III varicocele was significantly associated with decreased sperm motility on postoperative SA (OR 4.1, 95% CI 1.7-10.0, p=0.002), and larger left testicle volume (OR 1.4, 95% CI 1.1-1.8, p=0.02) was associated with clinical "downgrading" after varicocelectomy. Conclusion A small but significant proportion of men experienced a "downgrading" of semen parameters after varicocelectomy. Larger left testis size was associated with clinical downgrading, whereas clinical grade III varicoceles were associated with lower post-treatment sperm motility. These data are critical for preoperative patient counseling.

Sexual Dysfunction Among Adolescent and Young Adult Men Diagnosed with Cancer.

Purpose: Adolescent and young adult (AYA) cancer patients frequently demonstrate sexual dysfunction; however, there is a lack of data quantifying the severity and frequency. Methods: Males aged 18-39 years, diagnosed with cancer of any kind and who were scheduled to begin, were actively receiving, or had completed cancer treatment within 6 months, were offered validated surveys during their oncology appointment. These surveys included the International Index of Erectile Function (IIEF-6), Masturbation Erection Index (MEI), 36-Item Short Form Survey, and 5-point Likert scales to assess their desire and ability to engage in sex and masturbation. Results: Forty subjects completed the IIEF survey with a mean score of 17.7 ± 11, erectile dysfunction (ED) prevalence accordingly was 58%. Thirty-eight subjects completed the MEI with a mean score of 25.3 ± 5.3, ED prevalence was again 58%. Age and IIEF scores demonstrated a statistically significant (p < 0.05, n = 38) Pearson's correlation coefficient of 0.40, patients younger than 30 years had an ED prevalence of 72% (mean IIEF 13), whereas patients aged 30 years and older had an ED prevalence of 45% (mean IIEF 22). All treatment modalities had ED rates >30%: chemotherapy demonstrated the highest prevalence at 64% (mean IIEF 17), whereas radiation therapy had the lowest prevalence at 33% (mean IIEF 23). Conclusion: This study demonstrates that the prevalence of sexual dysfunction among male AYA patients undergoing treatment for cancer is high. AYA oncologists should discuss potential sexual health concerns when treating this population. The exact cause of ED (non-organic vs. organic) within this group should be explored further.

Pilot study of the correlation of multiphoton tomography of ex vivo human testis with histology.

PURPOSE: Although microdissection testicular sperm extraction has become first line therapy for sperm retrieval in men with nonobstructive azoospermia, there are challenges to the procedure, including difficulty differentiating between seminiferous tubules with normal and abnormal spermatogenesis. Multiphoton microscopy illuminates tissue with a near infrared laser to elicit autofluorescence, which enables real-time imaging of unprocessed tissue without labels. We hypothesized that we could accurately characterize seminiferous tubular histology in humans using multiphoton microscopy. MATERIALS AND METHODS: Seven men with normal or abnormal spermatogenesis underwent testicular biopsies, which were imaged by multiphoton microscopy. We assessed these images in blinded fashion. The diagnosis rendered with multiphoton microscopy was then correlated with that of hematoxylin and eosin stained tissue. We evaluated the ability of multiphoton microscopy to differentiate normal from abnormal seminiferous tubules by examining autofluorescence characteristics and diameters, as imaged by multiphoton microscopy. Assessment was repeated with stained slides and results were compared. RESULTS: The overall concordance rate between multiphoton microscopy and stained slides was 86%. The seminiferous tubules of patients with nonobstructive azoospermia were smaller than those of controls when measured by multiphoton microscopy and staining (p <0.05). The proportion of normal tubules and the diameters obtained with multiphoton microscopy were not different from those obtained with hematoxylin and eosin (p >0.05). CONCLUSION: Multiphoton microscopy can be used to differentiate normal from abnormal spermatogenesis. Its characterization of seminiferous tubular architecture is similar to that provided by hematoxylin and eosin staining. Further investigation of the clinical applications of multiphoton microscopy may improve surgical sperm retrieval outcomes for patients with nonobstructive azoospermia.

Novel therapeutics for the management of castration-resistant prostate cancer (CRPC).

Androgen-deprivation therapy is the initial treatment for metastatic prostate cancer. Although highly effective, all men who live long enough will eventually experience disease progression and develop castration resistance. Patients who have castration-resistant prostate cancer (CRPC) have a median survival of ≈1-3 years. When evaluating novel therapies for CRPC, one must consider the endpoints measured for determination of response. We will discuss PSA, circulating tumour cells, progression-free survival, overall survival, and other endpoints used in clinical trials. Docetaxel and sipuleucel-T are currently the preferred first-line treatment options for patients with CRPC; cabazitaxel is a new option for patients after docetaxel failure. Patients with CRPC historically have very poor survival, underscoring the unmet need for novel therapeutics. Although many agents appear promising, well-designed randomized phase III trials are necessary to establish their impact on survival and health-related quality of life. Promising new therapies include hormonal agents, such as abiraterone and MDV3100, as well as other novel immunotherapeutics and anti-prostate-specific membrane antigen therapies. In the future, we anticipate therapies tailored to individual patients' malignancies using various molecular analyses.

Testosterone replacement therapy in the era of telemedicine.

The events of the 2019 SARS-CoV2 virus pandemic have all but ensured that telemedicine will remain an important aspect of patient care delivery. As health technologies evolve, so must physician practices. Currently, there is limited data on the management of testosterone replacement therapy (TRT) in the era of telemedicine. This review aims to explore the potential benefits and pitfalls of TRT management via telemedicine. We also propose a theoretical framework for TRT management via telemedicine. Telemedicine provides patients and physicians with a new mechanism for American Urological Association guideline-concordant TRT management that can increase patient access to care and provide a safe space for men who may otherwise not have been comfortable with in-person evaluation. However, there are significant limitations to the use of telemedicine for the management of TRT, including the inability to perform a physical exam, inability to administer specific medications, technological barriers, data security, and medical-legal considerations, and both patients and providers should engage in shared decision making before pursuing this approach. Understanding and acknowledging the potential pitfalls of telemedicine for TRT management will enable both patients and providers to achieve optimal outcomes and satisfaction.
