COVID-19 disease in clinical setting: impact on gonadal function, transmission risk, and sperm quality in young males.

Abstract Objectives We want to evaluate the possible presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in semen samples and semen quality, looking for a possible relationship between the infectious disease and fertility. Methods In this prospective study, we enrolled 15 consecutive men (age 18–50 years) with positive oropharyngeal swab to SARS-CoV-2 and classified, according to WHO criteria, in mild to moderate disease. A semen sample was collected to detect SARS-CoV viral RNA by the automated Real-Time PCR ELITe InGenius® system and the GeneFinderTM COVID-19 Plus RealAmp Kit assay (ELITechGroup, France). Analysis of semen characteristics was performed according to WHO laboratory manual 5th ed. for the examination and processing of human semen. Blood samples for the dosage of hormonal assay, procalcitonin, interleukin 6, C-reactive protein were obtained. Results SARS-CoV-2 RNA has not been detected in semen samples from any of the subjects analysed. Sperm analysis exhibited abnormal seminal values in 14 out of 15 patients (93.3%). Furthermore, no difference was detected regarding sperm quality between mild and moderate SARS-CoV-2 patients. No alteration in the inflammatory indices was observed in the studied population, as well gonadotropins and testosterone levels. Conclusions COVID patients studied exhibits alteration of the seminal fluid both in microscopic and macroscopic characteristics such as hypoposia and increased viscosity, which have not been detected in previous studies. The presence of viral RNA within the seminal fluid was excluded

The intra-meatal application of alprostadil cream (Vitaros\uae) improves drug efficacy and patient\u2019s satisfaction: results from a randomized, two-administration route, cross-over clinical trial

To investigate the efficacy, tolerability, and patient\u2019s preference of alprostadil cream for topical use administered within the urethral meatus versus the standard administration route, in erectile dysfunction (ED) treatment. Seventy-one patients (mean age 59.7 \ub1 9.0 years) affected by ED were analyzed in this multicenter, randomized, two-administration routes, cross-over trial. All patients received a single dose of alprostadil cream applying the dispenser to the tip of the penis (without contacting the urethral meatus) (Standard administration route or ST.AR) alternating with a single dose of alprostadil cream applying the dispenser within the urethral meatus (New administration route or NEW.AR) separated by a one-week washout period, according to randomization. The primary objective of the study was to evaluate the change in International Index of Erectile Function (IIEF-5) total score from baseline to the control visit by comparing the ST.AR and NEW.AR. Secondary objectives of the study were to compare the different methods of administration by evaluating the change in the Sexual Encounter Profile (SEP-2 and SEP-3) questionnaire score and the Patient Reported Outcomes (PROs) by scoring the Patient Self- Assessment of Erection (PSAE) questionnaire. The treatment safety profile was assessed by analysis of adverse events (AEs). Based on the study findings it is evident that the NEW.AR is more efficacious than the ST.AR in improving IIEF-5 and SEP scores from baseline to control visit (IIEF-5: +3.8 vs +6.3; p < 0.001; positive response to SEP-2: 10 vs 27; p = 0.002) and in terms of PSAE (a significant improvement from the baseline in 31% of patients; p < 0.001). As regards the safety profile, no difference in terms of local and systemic side effects was found
