Purpose Ongoing evidence has suggested the role of male factor infertility as a potential predictor of mortality and general health status. The aim of the present review is to update the current knowledge base regarding the association between male factor infertility and general health through a critical review of the literature. Materials and Methods A systematic review of the literature was carried out from inception to November 2019 in order to evaluate significant associations between male infertility and adverse health outcomes such as cardiovascular, oncologic, metabolic and autoimmune diseases as well as overall mortality. Results In all, 27 studies met inclusion criteria and were critically examined. Five studies examined male infertility and cardiovascular disease risk, 11 examined oncologic risk (e.g., overall cancer risk, testis and prostate cancer), 8 examined aggregate chronic medical diseases and 5 infertility related to incidence of mortality, for a total of 599,807 men diagnosed with any male factor infertility covering a period from 1916 to 2016. Conclusions A man's fertility and overall health appear to be interconnected. Therefore, a diagnosis of male infertility may allow a window into future comorbidity and/or mortality which may help guide clinical decisions and counseling. Several possible etiologies such as genetic, epigenetic, developmental, and lifestyle-based factors need to be further evaluated in order to establish the underlying mechanisms between male infertility and health.

Introduction Hydraulic penile prostheses have shown an overall good mechanical reliability up to 10 years after surgery; however, few data have been published on very long-term follow-up. Aim We looked at long-term (≥15 years) complications, including functional and quality of life (QoL) outcomes, after 3-piece inflatable penile prosthesis (IPP) implantation in patients with erectile dysfunction (ED). Methods Data regarding 149 patients submitting to IPP placement before 2001 were analyzed. All patients were implanted with AMS CX and Ultrex Plus 3-piece prostheses. Main Outcome Measure Patients were reassessed to evaluate rates of complications and functional outcomes. The validated questionnaire Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) was used to assess patient QoL. Kaplan-Meier analysis estimated the probability of prosthesis survival (defined as working device/not-explanted). Results Median follow-up of 51 patients was 206 months (interquartile range [IQR], 145–257). The etiology of ED was vasculogenic (n = 20; 39%), Peyronie’s disease (n = 15; 29%), pelvic surgery (n = 4; 7.8%), organic other than vasculogenic (n = 3; 5.9%), or other (n = 9; 18%). Throughout the follow-up, 24 patients (49%) experienced complications: mechanical failure (n = 19; 79%), pain (n = 3; 12%), orgasmic dysfunctions (n = 1; 4.5%), or device infection (n = 1; 4.5%). The estimated IPP survival was 53% (95% CI, 36–67) at 20-year follow-up. Baseline characteristics (age, Charlson comorbidity index, body mass index, and erectile dysfunction etiology) were not significantly associated with the risk of IPP failure over time by Cox regression analysis. At 20-year follow-up, 41% (95% CI, 19–49) of the patients were still using the device. Among them, QoLSPP median domain scores were high: functional 22/25 (IQR, 20–23), relational 17/20 (IQR, 15–18), personal 14/15 (IQR, 12–15), and social 14/15 (IQR, 11–15). Clinical Implications The longevity of the device and long-term satisfaction rates should be comprehensively discussed during patient consultation for IPP surgery. Strengths & Limitations To our knowledge, this is the first study reporting long-term QoL outcomes using a dedicated questionnaire for penile prostheses. The low response rate for the telephone interviews, the retrospective design of the study, and the relatively small number of patients are the main limitations. Conclusion Long-term follow-up data after IPP placement showed that almost half of the devices still worked properly 20 years after the original penile implant, as 60% of patients were still using the device with high satisfaction and adequate QoL outcomes. Both patients and physicians should be aware of the expected life and outcomes of IPP implants.

A proportion of men are infertile despite having normal medical history/physical examination and normal semen analysis. We aimed to assess whether normal sperm parameters per se account for male factor fertility. 1,957 infertile men were compared with 103 age-comparable fertile controls. Semen analysis was based on 2010 World Health Organization reference criteria. Of all, 12.1% of infertile men and 40.8% of fertile men presented with normal sperm parameters. Among fertile men, 36.9% had isolated sperm abnormalities and 22.3% men showed two or more concomitant sperm abnormalities. Serum total testosterone was higher in infertile men with normal sperm parameters compared to those with ≥2 sperm abnormalities or azoospermia, but similar to those with isolated sperm abnormalities (p ≤ .001). Circulating hormones were similar among sperm parameters groups in fertile men. At multivariable analyses, testicular volume (OR 1.12, p ≤ .001) and FSH (OR 0.8, p ≤ .001) were associated with normal sperm parameters. Overall, the longer the infertility period, the greater the number of sperm parameters abnormalities (p < .01). In conclusion, we found that 12% of infertile men and only 41% of fertile men present with normal sperm parameters. Normal sperm parameters per se do not reliably account for fertility in the real-life setting.
