Does the presence of human papillomavirus (HPV) in semen impact seminal parameters and sperm DNA quality in white European men seeking medical help for primary couple's infertility? SUMMARY ANSWER: HPV seminal infections involving high-risk (HR) genotypes are associated with impaired sperm progressive motility and sperm DNA fragmentation (SDF) values.WHAT IS KNOWN ALREADY: HPV is commonly present in semen samples. However, whether the presence of HPV in semen is actually associated with impaired sperm parameters and SDF values have yet to be elucidated. STUDY DESIGN, SIZE, DURATION:In this cross-sectional study, complete demographic, clinical and laboratory data from 729 infertile men were analysed.PARTICIPANTS/MATERIALS, SETTING, METHODS: Health-significant comorbidities were scored with the Charlson comorbidity index (CCI). Serum hormones and SDF index (measured by the sperm chromatin structure assay [SCSA]) were measured in every patient (SDF ≥30% was defined as pathological). Semen analysis was based on 2010 World Health Organisation reference criteria. Amplification by nested PCR was used to detect HPV-DNA sequences in semen samples. Descriptive statistics and linear regression models were used to test the association between the presence of HPV and clinical and seminal characteristics in the whole cohort. MAIN RESULTS AND THE ROLE OF CHANCE:The overall rate of HPV positivity was 15.5% (113/729). Overall, 78/729 (10.7%) and 35/729 (4.8%) patients had HR HPV+ and low-risk HPV+, respectively. HPV16 was the most prevalent type (22.1%), followed by HPV43 (10.6%), HPV56 and HPV42 (both 8.8%). No differences were found in terms of clinical and hormonal characteristics between patients with or without seminal HPV. Sperm progressive motility was significantly lower (P = 0.01) while SDF values were higher (P = 0.005) in HPV+ men compared to those with no HPV. In particular, HR HPV+ men had lower sperm progressive motility (P = 0.007) and higher SDF values (P = 0.003) than those with a negative HPV test. Univariable analysis showed that HR HPV+ was associated with impaired sperm progressive motility (P = 0.002) and SDF values (P = 0.003). In the multivariable analysis, age, FSH levels and testicular volume were significantly associated with impaired sperm progressive motility (all P ≤ 0.04). Conversely BMI, CCI, smoking habits and HPV status were not.

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.
