The impact of COVID-19 on the male genital tract: a qualitative literature review of sexual transmission and fertility implications.

The angiotensin-converting enzyme 2 receptor (ACE2) appears to be widely expressed in cells in the testes, predominantly in spermatogonia, Sertoli cells, and Leydig cells, and its co-expression with transmembrane protease serine 2 (TMPRSS2) is essential for the entry of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). For this reason, the male reproductive system could be considered a potential target for SARS-CoV-2, as well as a possible reservoir of infection. However, to date, there is very little evidence about the presence of SARS-CoV-2 in semen and testicular samples. The aim of this paper was to review the current evidence regarding the impact of SARS-CoV-2 on male fertility and sexual health, with a particular focus on reproductive hormones, the presence of the virus in seminal fluid and testis, and its impact on fertility parameters. We found very limited evidence reporting the presence of SARS-CoV-2 in semen and testicular samples, and the impact of SARS-CoV-2 on reproductive hormones and fertility parameters is unclear. The quality of the examined studies was poor due to the small sample size and several selection biases, precluding definitive conclusions. Hence, future well-designed prospective studies are needed to assess the real impact of SARS-CoV-2 on male reproductive function.

Perioperative outcomes of patients undergoing urological elective surgery during the COVID-19 pandemic: a national overview across 28 Italian institutions.

INTRODUCTION: The aim of this study was to assess the safety of elective urological surgery performed during the pandemic by estimating the prevalence of COVID-19-like symptoms in the postoperative period and its correlation with perioperative and clinical factors. MATERIAL AND METHODS: In this multicenter, observational study we recorded clinical, surgical and postoperative data of consecutive patients undergoing elective urological surgery in 28 different institutions across Italy during initial stage of the COVID-19 pandemic (between February 24 and March 30, 2020, inclusive). RESULTS: A total of 1943 patients were enrolled. In 12%, 7.1%, 21.3%, 56.7% and 2.6% of cases an open, laparoscopic, robotic, endoscopic or percutaneous surgical approach was performed, respectively. Overall, 166 (8.5%) postoperative complications were registered, 77 (3.9%) surgical and 89 (4.6%) medical. Twenty-eight (1.4%) patients were readmitted to hospital after discharge and 13 (0.7%) died. In the 30 days following discharge, fever and respiratory symptoms were recorded in 101 (5.2%) and 60 (3.1%) patients. At multivariable analysis, not performing nasopharyngeal swab at hospital admission (HR 2.3; CI 95% 1.01-5.19; p = 0.04) was independently associated with risk of developing postoperative medical complications. Number of patients in the facility was confirmed as an independent predictor of experiencing postoperative respiratory symptoms (p = 0.047, HR:1.12; CI95% 1.00-1.05), while COVID-19-free type of hospitalization facility was a strong independent protective factor (p = 0.02, HR:0.23, CI95% 0.07-0.79). CONCLUSIONS: Performing elective surgery during the COVID-19 pandemic does not seem to affect perioperative outcomes as long as proper preventive measures are adopted, including nasopharyngeal swab before hospital admission and hospitalization in dedicated COVID-19-free facilities.
