Pharmacological therapies for male infertility.

Male factor infertility is a multifaceted problem that affects approximately 50% of couples suffering from infertility. Causes of male infertility include endocrine disturbances, gonadotoxins, genetic abnormalities, varicocele, malignancies, infections, congenital or acquired urogenital abnormalities, iatrogenic factors, immunological factors, and idiopathic reasons. There are a variety of treatment options for male infertility, depending on the underlying cause(s). These can include surgical treatments, medical/hormonal therapies, and assisted reproductive techniques (ART), which can be combined with surgical sperm retrieval (SSR) if necessary. In this review article, the pharmacological therapies for male infertility are grouped by their underlying causes. Some of these therapies are targeted and specific, while others are used empirically to treat idiopathic male infertility. This will include treatments to optimize infertility in patients who have hypogonadism, ejaculatory dysfunction, infections, or idiopathic male infertility. Finally, we will provide an overview of the future directions of pharmacological therapies for male infertility. Significance Statement Male infertility is a significant worldwide problem. Detailed knowledge of the pharmacological therapies available will ensure the prescription of appropriate therapy and avoid the use of unnecessary or harmful treatments.

Sperm DNA fragmentation and infertility: a narrative review.

PURPOSE: The purpose of this narrative review is to provide a practical understanding of sperm DNA fragmentation (SDF) in the management of male infertility. METHODS: A search for systematic reviews and meta-analyses (SRMA) on SDF between April 1st, 2018 and April 1st, 2023 was performed using PubMed and articles were selected as per their relevance to the topic. Guidelines from major societies were also reviewed. Three clinical cases are reported and discussed. RESULTS: The search initially identified 80 articles. We selected 13 SRMAs based on their relevance to the topic. Of the 13 SRMAs, 7 evaluated the effect of SDF on assisted reproductive technology (ART) outcomes and recurrent pregnancy loss, 3 studied the effect of varicocele repair on SDF, and 3 evaluated the role of SDF involving lifestyle and environmental health factors including body mass index and male factor treatment strategies. CONCLUSION: Evidence suggests that increased SDF has a negative impact on natural pregnancy and ART outcomes. SDF testing may be particularly important in the infertility evaluation of men with varicoceles, idiopathic or unexplained infertility, recurrent pregnancy loss, or previous ART failure. Further studies are needed on SDF testing and the implications it can have on male factor infertility and pregnancy outcomes as well as its implementation in the setting of ART.

Unconsummated marriage: a systematic review of etiological factors and clinical management.

BACKGROUND: Unconsummated marriage (UCM) is the inability of the heterosexual married couple to have penovaginal sexual intercourse. AIM: The study sought to systematically review current evidence regarding the etiological factors and clinical management of UCM. METHODS: A comprehensive bibliographic search on the MEDLINE, Scopus, Web of Science, and Cochrane Library databases was performed in June 2023. Studies were selected if they described married couples who never had sexual intercourse in case report or case series evaluating the related causes and/or management and reporting data with qualitative, quantitative, or mixed methods. The review was reported according to PRISMA (Preferred Reporting Items for Systematic Review and Meta-analyses) statement and registered in PROSPERO with ID CRD42023433040. RESULTS: A total of 27 studies including 1638 males and 1587 females were selected. Eight (29.6%) articles were case reports involving a single couple and 19 (70.4%) studies were case series. Mean Murad score was 4.1 (range, 1-8) showing low-intermediate overall study quality. All articles had a level of evidence of 4. Most of studies were conducted in Egypt (n = 5 [18.4%]), Israel (n = 4 [14.9%]), and the United States (n = 4 [14.9%]). The mean age of males and females varied between 24.2 and 37.6 years and from 21 to 27.4 years, respectively. The reasons for the medical visit that led to the diagnosis of UCM were inability to consummate in 23 (85.2%) studies, inability to conceive in 1 (3.7%) article, and mixed in 3 (11.1%) articles. The mean duration of UCM varied from 7 days to 3.5 years. Eight studies involving both men and women showed that vaginismus (8.4%-81%) and erectile dysfunction (10.5%-61%) were the most common causes of UCM. Three articles reported that 16.6% to 26% of all UCM cases were due to both male and female factors. Sildenafil, tadalafil, intracavernosal injection, penile plication, female genital reconstructive surgery, vaginal dilators, lubricants, psychosexual therapy, and sex education were the various treatment modalities in 27 studies to achieve consummation rate of 66.6% to 100%. STRENGTHS & LIMITATIONS: A strength is that this is the first systematic review covering the entire spectrum of UCM. Limitations comprised the low quality of most of the included articles and the large percentage of UCM cases probably not published. CONCLUSION: Erectile dysfunction and vaginismus are the most reported causes of UCM; however, a strong psychological component certainly underlies a significant number of cases. A multidisciplinary approach based on strategic integration of sex education, medical therapy, psychosexual support, and surgical treatment would seem the most suitable option to manage couples with UCM.

Male infertility.

It is estimated that infertility affects 8-12% of couples globally, with a male factor being a primary or contributing cause in approximately 50% of couples. Causes of male subfertility vary highly, but can be related to congenital, acquired, or idiopathic factors that impair spermatogenesis. Many health conditions can affect male fertility, which underscores the need for a thorough evaluation of patients to identify treatable or reversible lifestyle factors or medical conditions. Although semen analysis remains the cornerstone for evaluating male infertility, advanced diagnostic tests to investigate sperm quality and function have been developed to improve diagnosis and management. The use of assisted reproductive techniques has also substantially improved the ability of couples with infertility to have biological children. This Seminar aims to provide a comprehensive overview of the assessment and management of men with infertility, along with current controversies and future endeavours.

Cystic fibrosis transmembrane conductance regulator-related male infertility: Relevance of genetic testing & counselling in Indian population.

BACKGROUND & OBJECTIVES: Due to limited information available on the frequency and spectrum of cystic fibrosis (CF) transmembrane conductance regulator (CFTR) gene mutations in congenital bilateral absence of vas deferens (CBAVD) in Indian population, it is difficult to provide accurate genetic counselling to couples. The present study was undertaken to investigate the spectrum and frequency of CFTR gene mutations in Indian men with CBAVD and to determine the female CF carrier status. METHODS: Direct DNA sequencing of the CFTR gene was carried out in eighty CBAVD men, their female partners and fifty controls from the general population. Pathological significance of the identified novel CFTR gene variants was carried out using in silico tools. Appropriate genetic counselling was provided to the couples prior to intracytoplasmic sperm injection (ICSI). RESULTS: A significant association was observed for CFTR gene variants in Indian CBAVD men versus controls (odds ratio: 12.1; 95% confidence interval: 4.8-30.4; P<0.0001). A total of 20 CFTR gene variants were identified in 53 CBAVD men. Eight novel missense CFTR gene variants (L214V, A238P, E379V, L578I, F587L, L926W, R1325K and R1453Q); two novel splice-site gene variants (c.1-30C>G and IVS1+2T>G) and ten previously reported mutations (R75Q, c.1210-12[5], F508del, A309G, R334W, I444T, R668C, R709X, A1285V and Q1352H) were detected in CBAVD men. The novel and reported CFTR gene mutations were L926W (2.5%, P=0.26), R1453Q (2.5%, P=0.26), F508del (8.75%, P=0.03) and c.1210-12[5] (42.5%, P=0.002). A total of 13 (16.2%) female partners were found to be a CF carrier. Nine couples had a risk of transmitting mutant CFTR allele to the offspring. INTERPRETATION & CONCLUSIONS: The heterogeneous spectrum of CFTR gene in Indian population suggests the necessity of screening CBAVD men and female partners for accurate genetic counselling prior to undergoing ICSI.

Cadaveric Penile Prosthesis Workshop training improves surgical confidence levels of urologists: South Asian Society for Sexual Medicine course survey.

OBJECTIVES: To analyze the impact of South Asia's first cadaveric hands-on workshop on urologists' training in inflatable penile prosthesis surgery. METHODS: A total of 72 urologists/andrologists participated in the 2019 South Asian Society for Sexual Medicine Pre-congress Penile Prosthesis hands-on workshop. The workshop included 4 h of lectures and 2 h of hands-on cadaveric laboratory experience using three-piece inflatable penile prosthesis. The Shapiro-Wilk test was used on self-rated procedural confidence levels, which proved the normality. A non-parametric McNemar test was used to examine the change in the number of correct answers. RESULTS: Of those who attended the cadaver laboratory, just 45 who answered the survey both before and after the workshop were included for analysis. Significant objective improvements were noted in procedural knowledge test scores (44.30 ± 0.027 vs 72.44 ± 0.024, P < 0.05) and median surgical confidence levels (4 vs 3 and 2, P < 0.001) of the urologists after the completion of the workshop. CONCLUSIONS: Cadaveric hands-on workshop training improves urologists' procedural knowledge and surgical confidence levels in carrying out three-piece inflatable penile prosthesis surgery. The feasibility of such workshops should be considered in increasing the surgical expertise of general urologists in prosthetic urology.

Cystic fibrosis transmembrane conductance regulator (CFTR) gene abnormalities in Indian males with congenital bilateral absence of vas deferens & renal anomalies.

BACKGROUND & OBJECTIVES: The role of cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations in congenital bilateral absence of vas deferens and unilateral renal agenesis (CBAVD-URA) has been controversial. Here, we report the cases of five Indian males with CBAVD-URA. The objective was to evaluate the presence or absence of CFTR gene mutations and variants in CBAVD-URA. The female partners of these males were also screened for cystic fibrosis (CF) carrier status. METHODS: Direct DNA sequencing of CFTR gene was carried out in five Indian infertile males having CBAVD-URA. Female partners (n=5) and healthy controls (n=32) were also screened. RESULTS: Three potential regulatory CFTR gene variants (c.1540A>G, c.2694T>G and c.4521G>A) were detected along with IVS8-5T mutation in three infertile males with CBAVD-URA. Five novel CFTR gene variants (c.621+91A>G, c.2752+106A>T, c.2751+85_88delTA, c.3120+529InsC and c.4375-69C>T), four potential regulatory CFTR gene variants (M470V, T854T, P1290P, Q1463Q) and seven previously reported CFTR gene variants (c.196+12T>C, c.875+40A>G, c.3041-71G>C, c.3271+42A>T, c.3272-93T>C, c.3500-140A>C and c.3601-65C>A) were detected in infertile men having CBAVD and renal anomalies Interpretation & conclusions: Based on our findings, we speculate that CBAVD-URA may also be attributed to CFTR gene mutations and can be considered as CFTR-related disorder (CFTR-RD). The CFTR gene mutation screening may be offered to CBAVD-URA men and their female partners undergoing ICSI. Further studies need to be done in a large sample to confirm the findings.

Therapeutic Effects of Oral Nutritional Supplements during Haemodialysis: Physician's Experience.

OBJECTIVES: To evaluate the effects of predialytic oral nutritional supplementation in chronic kidney disease (CKD) patients on maintenance haemodialysis (MHD). METHODS: NEPRO HP was provided to 77 CKD patients on maintenance haemodialysis (MHD) over 3 months. Efficacy parameters were improvement in albumin levels, weight and haemoglobin levels; safety parameters were serum potassium and phosphorus values; other parameters were SGA and MIS scores. RESULTS: Mean serum albumin values showed a statistically significant increase. There was a statistically significant improvement in the mean body weight and haemoglobin of the patients in the second and third months of treatment. Serum phosphorus and potassium levels did not change in a statistically significant manner. There was improvement in nourishment status as detected by MIS and SGA scores. Two patients expired during the course of the study. CONCLUSION: Predialytic oral supplementation with NEPRO HP improves nutritional status of CKD patients on MHD.

Varicocele and nonobstructive azoospermia.

Approximately 15% of men in the general population have varicoceles, and varicoceles are diagnosed in 40% of men presenting for fertility evaluations. One percent of men in the general population are azoospermic, and 15% of men presenting for fertility evaluations are diagnosed with azoospermia. This article aims to review the impact of varicoceles on testicular function in men with azoospermia, the impact of varicocele repair on the semen parameters of azoospermic men, and the impact of varicocele repair on sperm retrieval and pregnancy outcomes when the male partner remains azoospermic after varicocele repair.

Sixth edition of the World Health Organization laboratory manual of semen analysis: Updates and essential take away for busy clinicians.

Background: Semen analysis is the cornerstone for male fertility evaluation. In 2021, the World Health Organization (WHO) released its 6th edition of semen analysis manual. Methods: We highlight the main changes in the latest 6th edition of the WHO manual of semen analysis and their possible interpretations. Results: The manual is highly comprehensive, offering detailed information, and is widely regarded as an excellent technical reference for laboratory staff. Nevertheless, several aspects of the manual require further elucidation for infertility practitioners. Conclusion: The recently published 6th edition of the WHO manual provides a strong framework for the assessment and processing of human semen. Grasping the modifications introduced in this updated edition and their clinical significance can enhance the quality of patient care.

Isolated teratozoospermia: revisiting its relevance in male infertility: a narrative review.

Background and Objective: Basic semen analysis is the first step in the evaluation of male infertility. It includes an assessment of sperm morphology which is believed to reflect on overall spermatogenesis and sperm function. Teratozoospermia, defined as abnormal sperm morphology, is frequently present in association with severe oligoasthenozoospermia, but isolated teratozoospermia (in the presence of normal counts and motility) is a poorly understood clinical entity with conflicting implications in terms of fertility potential and treatment strategies. The following paper aims to: (I) discuss the classification of sperm morphology, causes, and molecular mechanism of teratozoospermia; (II) analyze the clinical significance and potential treatment options of isolated teratozoospermia as a cause of male infertility and a predictor of fertility outcome; and (III) provide a SWOT (strengths, weaknesses, opportunities, and threats) analysis based on the existing literature on this topic. Methods: A comprehensive search from database inception to 25 April 2023 was conducted in PubMed for relevant papers relating to isolated teratozoospermia in male infertility. Finally, seven systematic reviews/reviews/meta-analyses and 81 original articles were synthesized into the current narrative review. Key Content and Findings: Classification of sperm morphology has evolved significantly since the first edition of the World Health Organization (WHO) Manual of Human Semen Analysis. Kruger's strict criteria are the most used classification and have been shown to correlate with fertility outcomes. There are many causes of teratozoospermia including genetic and environmental factors and physical conditions like varicocele. Teratozoospermia correlates with sperm DNA damage, elevated oxidative stress, low antioxidant function, and apoptotic alterations, which can result in impaired spermatozoa function and lower pregnancy rates. However, the clinical correlation between teratozoospermia and assisted reproductive technology (ART) outcome shows conflicting data with recent meta-analyses suggesting that isolated teratozoospermia was not associated with poor fertility outcomes from ART and that intrauterine insemination (IUI) can be an effective option even in the presence of teratozoospermia. There is very limited data on effective therapeutic options to treat idiopathic isolated teratozoospermia. The opportunity for future research is huge to fill the gap in the medical literature on this topic. Conclusions: Contemporary literature on isolated teratozoospermia shows conflicting results in terms of its actual clinical implication in male infertility and the utility of available treatment options. Further research is warranted on this clinical entity to improve sperm function and future paternity.

Varicocele and male infertility conundrum: Making sense of a never-ending story for the busy clinician.

Background: Varicocele is a common occurrence, particularly among men with primary and secondary infertility. There has been extensive research into the management of varicocele in the context of male infertility. Methods: This article aims to explore the variations in clinical practice in diagnosing and managing varicoceles in infertile men. A summary of the current recommendations on varicocele management from professional societies is included. Results: Substantial gaps in knowledge persist regarding varicoceles and male infertility, with significant variation in clinical approaches, despite the wealth of existing data in the medical literature. Conclusion: The existing literature leaves many questions surrounding varicocele management in infertile men unanswered. This lack of clarity contributes to the ongoing controversy among clinicians in the field. New research is essential to address these contentious points and areas of debate.

The Andrological Landscape in the Twenty-First Century: Making Sense of the Advances in Male Infertility Management for the Busy Clinicians.

Male infertility represents a significant global problem due to its essential health, social, and economic implications. It is unsurprising that scientific research is very active in this area and that advances in the diagnostic and therapeutic fields are notable. This review presents the main diagnostic advances in male infertility, starting from the changes made in the latest WHO Manual of semen analysis and discussing the more molecular aspects inherent to "omics". Furthermore, the usefulness of artificial intelligence in male infertility diagnostics and the latest advances in varicocele diagnosis will be discussed. In particular, the diagnostic path of male infertility is increasingly moving towards a personalized approach to the search for the specific biomarkers of infertility and the prediction of treatment response. The treatment of male infertility remains empirical in many regards, but despite that, advances have been made to help formulate evidence-based recommendations. Varicocele, the most common correctable cause of male infertility, has been explored for expanded indications for repair. The following expanded indications were discussed: elevated sperm DNA fragmentation, hypogonadism, orchalgia, and the role of varicocele repair in non-obstructive azoospermia. Moving forward with the available data, we discussed the stepwise approach to surgical sperm retrieval techniques and the current measures that have been investigated for optimizing such patients before testicular sperm extraction. Finally, the key points and expert recommendations regarding the best practice for diagnosing and treating men with infertility were summarized to conclude this review.

Impact of varicocele repair on semen parameters and spontaneous pregnancy: An endless debate put to rest.

There has been much controversy about the true value of varicocele repair for improving fertility and the chances of natural conception. This review summarizes the latest research findings, current professional societies' recommendations, and the conclusions of recent systematic reviews and meta-analyses. The current evidence suggests a positive role for varicocele repair in improving basic sperm parameters and increasing the likelihood of natural pregnancy.

Sperm morphology by strict criteria does not predict clinical pregnancy rate following intra-uterine insemination.

Objective: To determine the impact of abnormal sperm morphology of the pre-washed semen sample on the day of intrauterine insemination (IUI) on clinical pregnancy rates (CPR). Design: Cross sectional retrospective chart review. Setting: Academic fertility center. Patients: Couples undergoing (IUI) from May 2014 to March 2022. Interventions: Sperm morphology, by strict criteria, on the pre-washed IUI sample. Main outcomes Measures: To determine the association of sperm morphology with CPR. Results: Semen analysis reports, including Kruger strict criteria for morphology from the pre-washed IUI sample, were reviewed for 1,059 cycles, comprising 825 total treated couples.Of the total 1,059 cycles,15.1% resulted in clinical pregnancy. When categorized by strict morphology ≥4% (normal morphology), (3%-2%) [mild-moderate teratozoospermia (TZS)], and ≤1% (severe TZS), the CPR was 16%, 13%, and 10%, respectively (p value 0.30). Early spontaneous miscarriage rate was 4% and when stratified by morphology ≥4% (3%-2%), and ≤1%, was 3%, 1%, and 0%, respectively (p value 0.20).In couples with isolated TZS, the pregnancy rate was 16% in the normal morphology group, 14% in the mild-moderate group, and 8% in the severe group. (p value 0.30).In the multivariate logistic regression, sperm morphology, mild/moderate TZS vs normal forms (OR = 0.99, 95% CI [0.94-1.1]), severe TZS vs normal forms (OR = 0.98, 95% CI [0.0.83-1.1]), was not a predictor of CPR. The Pre-wash TMSC (OR = 1.0, 95% CI [0.996-1.00]) was also not predictive of CPR.The only predictive factor of CPR in IUI was the PWTMSC (OR = 1.03, 95%CI [1.00-1.06). Conclusions: The morphology of the pre-washed sample on the day of IUI did not find a difference in CPR, neither in miscarriage rate following IUI, in couples with normal or abnormal sperm morphology, including severe TZS.Mild, moderate, or severe TZS in the semen sample should not exclude couples to attempt an IUI procedure.

Effectiveness of, and Satisfaction with, a Microsurgical Testicular Sperm Extraction Knowledge and Skills Masterclass for a World-Wide Audience.

PURPOSE: This is the first study to assess the impact of an online microsurgical testicular sperm extraction (mTESE) masterclass. We: 1) describe the masterclass's scientific content; 2) appraise the participants' acquisition of knowledge; 3) gauge whether the extent of improvement of the participants' knowledge/skills was influenced by demographic/professional attributes; and 4) evaluate the participants' satisfaction. MATERIALS AND METHODS: This masterclass comprised five didactic lectures followed by 4 case discussions. Online surveys assessed the above objectives using a baseline questionnaire including demographics and past mTESE experience/training, a 24-question pre- and post-quiz, and a satisfaction questionnaire. RESULTS: Participants were between 20-70 years old, with 80.37% males, mainly from Asia, Africa, and Europe, from clinical backgrounds (69.3%), and in public practice (64.4%). Half the sample reported no past mTESE training and very low skills, ≈60% wanted considerably more training, and 50% felt that good training was not readily available. Satisfaction was 98% to >99%. Pre- and post-quiz comparisons confirmed remarkable improvements in knowledge/skills, exhibiting five striking characteristics. Improvements were a) Broad i.e., across 19 of the 24 mTESE questions; b) Deep, of magnitude, as pre-/post-quiz scores improved from mean 13.71±4.13 to 17.06±4.73; c) Highly significant, consistently with p-values <0.001; d) Inclusive i.e., all participants enhanced their mTESE knowledge/skills regardless of demographic/professional attributes; and, e) Differential, e.g., non-clinical/clinical participants improved, but the former improved relatively significantly more, those with ≤5-year experience improved significantly more than those with >5-year, those in public practice significantly more than private practice participants, and those with lower self-rating in performing mTESE significantly more than those with higher self-rating. CONCLUSIONS: The masterclass was successful with very high satisfaction levels, and markedly improved mTESE knowledge/skills among the participants. Global Andrology Forum's model can be adopted by organizations with similar goals. Future research needs to evaluate such training to develop a practically non-existent evidence base.

The Global Andrology Forum (GAF): Structure, Roles, Functioning and Outcomes: An Online Model for Collaborative Research.

PURPOSE: There are no published examples of a global online research collaborative in andrology. We describe the development, profile and member characteristics of the first consortium of this type, the Global Andrology Forum (GAF). MATERIALS AND METHODS: An online survey sent to all GAF members collected demographic information (sex, age, experience, academic title, degrees, country, specialty, profession). It also tapped data on members' characteristics e.g., skills in research, software and statistics; preferred activities; time commitments; expected roles; and interest in participating in research, in GAF's scientific activities and collaborative online research. The findings were analyzed and tabulated. We outline members' demographic and professional characteristics and scientific achievements to date. A narrative approach outlined GAF's structure and functioning. RESULTS: A total of 418 out of 540 members completed the survey and were included in the analysis (77.4% response rate). The sample comprised mainly urologists (34.2%) and a third of the respondents had practiced for >15 years (33.3%). Up to 86.1% of the members expressed interest in being actively engaged in writing scientific articles. A third of the sample (37.1%) could dedicate 4 to 6 hours/week. Few respondents reported skills in statistics and artwork (2.6% and 1.9% respectively). Members were assigned to specific roles based on their expertise and experiences. Collaborative working ensured the timely completion of projects while maintaining quality. For outcomes, GAF published 29 original articles within one year of its creation, with authors from 48 countries spanning topics that included varicocele, sperm DNA damage, oxidative stress, semen analysis and male infertility, oocyte/embryo, and laboratory issues of assisted reproductive technique (ART) and male infertility evaluation. CONCLUSIONS: GAF is a successful global online andrology research model. A healthy number of scientific articles have been published. Given such effectiveness, adopting the GAF model could be useful for other disciplines that wish to create and coordinate successful international online research groups.

Pushing the Boundaries for Evidenced-Based Practice: Can Online Training Enhance Andrology Research Capacity Worldwide? An Exploration of the Barriers and Enablers - The Global Andrology Forum.

PURPOSE: This is the first study to design and assess a research capacity building (RCB) specifically tailored for clinical and non-clinical andrology practitioners worldwide. We appraised: 1) the barriers and enablers to research among these practitioners; 2) attendees' satisfaction with the webinar; and 3) research knowledge acquisition as a result of the webinar (before/after quiz). MATERIALS AND METHODS: A online RCB webinar was designed, comprising two presentations in research design and systematic review/meta-analysis (SR/MA). An online survey using validated published questionnaires assessed the three above-stated objectives. Paired t-test compared the means of the pre- and post-webinar scores. Subgroup analysis was performed on the participants' professional background, sex, and number of years in practice. RESULTS: A total of 237 participants attended the webinar, of which 184 completed the survey and are included in the current analysis. Male participants were about double the females and 60.9% were from Asian countries. The most common research enablers were to publish scientific papers (14.8%) and to develop research (14.7%) or new skills (12.7%). The most common barriers were the lack of training in research (12.4%), training in research software (11.8%), and time for research (11.8%). Satisfaction with the webinar was considerably high (86.3%-88.4%) for the different features of the webinar. Compared to the pre-webinar knowledge level, there were significant improvements in participants' research knowledge acquisition after the webinar in terms of the total score for the quiz (13.7±4.31 vs. 21.5±4.7), as well as the scores for the study design (7.12±2.37 vs. 11.5±2.69) and SR/MA sessions (6.63±2.63 vs. 9.93±2.49) (p<0.001 for each). CONCLUSIONS: Clinical and non-clinical andrology webinar attendees recognized the importance of research and exhibited a range of research skills, knowledge and experience. There were significant improvements in the participants' knowledge and understanding of the components of scientific research. We propose an RCB model that can be implemented and further modeled by organizations with similar academic research goals.
