RESUMO

Currently, most men with infertility cannot be given an aetiology, which reflects a lack of knowledge around gamete production and how it is affected by genetics and the environment. A failure to recognize the burden of male infertility and its potential as a biomarker for systemic illness exists. The absence of such knowledge results in patients generally being treated as a uniform group, for whom the strategy is to bypass the causality using medically assisted reproduction (MAR) techniques. In doing so, opportunities to prevent co-morbidity are missed and the burden of MAR is shifted to the woman. To advance understanding of men's reproductive health, longitudinal and multi-national centres for data and sample collection are essential. Such programmes must enable an integrated view of the consequences of genetics, epigenetics and environmental factors on fertility and offspring health. Definition and possible amelioration of the consequences of MAR for conceived children are needed. Inherent in this statement is the necessity to promote fertility restoration and/or use the least invasive MAR strategy available. To achieve this aim, protocols must be rigorously tested and the move towards personalized medicine encouraged. Equally, education of the public, governments and clinicians on the frequency and consequences of infertility is needed. Health options, including male contraceptives, must be expanded, and the opportunities encompassed in such investment understood. The pressing questions related to male reproductive health, spanning the spectrum of andrology are identified in the Expert Recommendation.

RESUMO

The male contribution to a couple suffering with adverse early pregnancy outcomes is being increasingly investigated. Seminal oxidative stress is considered to cause sperm DNA damage, thus affecting the functional capacity of the sperm. Multiple lines of evidence support an association between elevated seminal reactive oxygen species (ROS) and infertility. In the setting of assisted reproduction various factors in the in vitro environment, differing from the in vivo environment, may exacerbate oxidative stress. Furthermore, seminal ROS levels have been found to be higher in the male partners of couple's affected by both spontaneous and recurrent pregnancy loss. There are several methods by which to assess ROS levels however they are costly, inconsistent and their incorporation into clinical practice is unclear. The value of ROS assessment lies in the ability to plan targeted therapies to improve pregnancy and live birth rates. As such, further robust study is required before firm conclusions can be made to inform clinical practice. We aim to review the available evidence regarding the role of seminal ROS in infertility and pregnancy loss.

RESUMO

Preliminary published data depict a much greater prevalence of males with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) referred for intensive care unit admission and severe sequelae in several countries. In this context, males seem to not only be more susceptible to the infection compared to female subjects, at least in Western countries, but their case fatality rate attributable to SARS-CoV-2 infection is also highest. Therefore, we may speculate that the different hormonal milieu could have a more profound pathophysiological role in association with SARS-CoV-2, with endogenous testosterone leaving men more prone to develop more serious complications related to the SARS-CoV-2 infection. Another option is that SARS-CoV-2 infection per se causes an acute stage of male hypogonadism, the depletion of androgenic action triggering serious or an even fatal course of the disease. Therefore, we strongly advocate the development of a prospective multidimensional andrological translational research project in men, which we called the PROTEGGIMI study. In this Opinion Article, we will not only highlight novel research activity in this area but also invite other researchers and learned scientific societies to join us in our efforts to understand an important and very newly discovered gap in knowledge, which may have serious implications for the lives of millions of men.

RESUMO

BACKGROUND: The oncological outcomes in men with clinically significant prostate cancer following focal cryotherapy are promising, although functional outcomes are under-reported. OBJECTIVE: To determine the impact of focal cryotherapy on urinary and sexual function, specifically assessing return to baseline function. DESIGN, SETTING, AND PARTICIPANTS: Between October 2013 and November 2016, 58 of 122 men who underwent focal cryotherapy for predominantly anterior clinically significant localised prostate cancer within a prospective registry returned patient-reported outcome measure questionnaires, which included International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF-15) questionnaires. INTERVENTION: Standard cryotherapy procedure using either the SeedNet or the Visual-ICE cryotherapy system. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Primary outcome was return to baseline function of IPSS score and IIEF erectile function (EF) subdomain. Cumulative incidence and Cox-regression analyses were performed. RESULTS AND LIMITATIONS: Probability of returning to baseline IPSS function was 78% at 12 mo and 87% at both 18 and 24 mo, with recovery seen up to 18 mo. For IIEF (EF domain), the probability of returning to baseline function was 85% at 12 mo and 89% at both 18 and 24 mo, with recovery seen up to 18 mo. Only the preoperative IIEF-EF score was associated with a poor outcome (hazard ratio 0.96, 95% confidence interval 0.93-0.999, p = 0.04). The main limitation was that only half of the patients returned their questionnaires. CONCLUSIONS: In men undergoing primary focal cryotherapy, there is a high degree of preservation of urinary and erectile function with return to baseline function occurring from 3 mo and continuing up to 18 mo after focal cryotherapy. PATIENT SUMMARY: In men who underwent focal cryotherapy for prostate cancer, approximately nine in 10 returned to their baseline urinary and sexual function. Keeping in mind that level 1 evidence and long-term data are still needed, in men who wish to preserve urinary and sexual function, focal cryotherapy may be considered an alternative treatment option to radical therapy.

RESUMO

OBJECTIVES: To assess change in functional outcomes after a second focal high-intensity focused ultrasonography (HIFU) treatment compared with outcomes after one focal HIFU treatment. PATIENTS AND METHODS: In this multicentre study (2005-2016), 821 men underwent focal HIFU for localized non-metastatic prostate cancer. The patient-reported outcome measures of International Prostate Symptom Score (IPSS), pad usage and erectile function (EF) score were prospectively collected for up to 3 years. To be included in the study, completion of at least one follow-up questionnaire was required. The primary outcome was comparison of change in functional outcomes between baseline and follow-up after one focal HIFU procedure vs after a second focal HIFU procedure, using IPSS, Expanded Prostate Cancer Index Composite (EPIC) and International Index of Erectile Function (IIEF) questionnaires. RESULTS: Of 821 men, 654 underwent one focal HIFU procedure and 167 underwent a second focal HIFU procedure. A total of 355 (54.3%) men undergoing one focal HIFU procedure and 65 (38.9%) with a second focal HIFU procedure returned follow-up questionnaires, respectively. The mean age and prostate-specific antigen level were 66.4 and 65.6 years, and 7.9 and 8.4 ng/mL, respectively. After one focal HIFU treatment, the mean change in IPSS was -0.03 (P = 0.02) and in IIEF (EF score) it was -0.4 (P = 0.02) at 1-2 years, with no subsequent decline. Absolute rates of erectile dysfunction increased from 9.9% to 20.8% (P = 0.08), leak-free continence decreased from 77.9% to 72.8% (P = 0.06) and pad-free continence from 98.6% to 94.8% (P = 0.07) at 1-2 years, respectively. IPSS prior to second focal HIFU treatment compared to baseline IPSS prior to first focal HIFU treatment was lower by -1.3 (P = 0.02), but mean IPSS change was +1.4 at 1-2 years (P = 0.03) and +1.2 at 2-3 years (P = 0.003) after the second focal HIFU treatment. The mean change in EF score after the second focal HIFU treatment was -0.2 at 1-2 years (P = 0.60) and -0.5 at 2-3 years (P = 0.10), with 17.8% and 6.2% of men with new erectile dysfunction. The rate of new pad use was 1.8% at 1-2 years and 2.6% at 2-3 years. CONCLUSION: A second focal HIFU procedure causes minor detrimental effects on urinary function and EF. These data can be used to counsel patients with non-metastatic prostate cancer prior to considering HIFU therapy.

RESUMO

Despite considerable public health initiatives in the past century, there remains a significant gender inequality in life expectancy. The Global Burden of Diseases study has highlighted that the life expectancy for men is 70.5years, compared with 75.6years for women. This discrepancy in mortality appears to be related to a disproportionately higher number of preventable and premature male deaths. Whilst there has been an increased focus on men's health, as evidenced by the establishment of men's health charities and governmental legislation promoting equality, a recent World Health Organization report has highlighted that there is still a prevailing misconception that the higher rate of premature mortality amongst men is a natural phenomenon. We explore the association of male sexual and reproductive health-related diseases and the potential role of a urologist in addressing gender inequality in life expectancy. PATIENT SUMMARY: In this report, we discuss the causes for the gender gap in life expectancy and highlight that men continue to have a higher rate of premature death than women, which is associated with diseases of the male reproductive system. Furthermore, this not only appears to be related to a number of metabolic and lifestyle factors, but may also be the result of the increased risk of cancer in men with sexual and reproductive health-related diseases.
