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.

Increased Creatine Kinase May Predict A Worse COVID-19 Outcome.

Early reports from Asia suggested that increased serum levels of the muscular enzyme creatine-(phospho)-kinase (CK/CPK) could be associated with a more severe prognosis in COVID-19. The aim of this single-center retrospective cohort study of 331 consecutive COVID-19 patients who were hospitalized during Italy's "first wave" was to verify this relationship, and to evaluate the role of possible confounding factors (age, body mass index, gender, and comorbidities). We subdivided our cohort in two groups, based on "severe" (n = 99) or "mild" (n = 232) outcomes. "Severe" disease is defined here as death and/or mechanical invasive ventilation, in contrast to "mild" patients, who were discharged alive with no need for invasive ventilation; this latter group could also include those patients who were treated with non-invasive ventilation. The CK levels at admission were higher in those subjects who later experienced more severe outcomes (median, 126; range, 10-1672 U/L, versus median, 82; range, 12-1499 U/L, p = 0.01), and hyperCKemia >200 U/L was associated with a worse prognosis. Regression analysis confirmed that increased CK acted as an independent predictor for a "severe" outcome. HyperCKemia was generally transient, returning to normal during hospitalization in the majority of both "severe" and "mild" patients. Although the direct infection of voluntary muscle is unproven, transient muscular dysfunction is common during the course of COVID-19. The influence of this novel coronavirus on voluntary muscle really needs to be clarified.

The Impact of the COVID-19 Quarantine on Sexual Life in Italy.

OBJECTIVE: The aim of the study is to evaluate how individual and couple's sexuality had changed during the COVID-19 pandemic-related quarantine. METHODS: A quantitative correlational research study was conducted, using a web-based survey. RESULTS: About 1576 participants were involved: 1018 women (64.6%) and 558 men (35.4%). A significant decline in the mean well-being scores during the quarantine, compared to before, was reported. A positive correlation between the well-being scores and the number of sexual intercourse (SI) before and during the quarantine was found. The mean number of SI decreased significantly during the quarantine. The main reasons were: poor privacy (43.2%) and lack of psychological stimuli (40.9%). About 1124 respondents (71.3%) did not report sexual desire (SD) reduction. A positive association between SD and SI during the quarantine was found. About 61.2% did not report autoerotism reduction. In those who reported decreased masturbation activity, the main causes were poor privacy (46.4%) and lack of desire (34.7%). We found that men presented lower SD during the quarantine, than women (P < 0.01). CONCLUSION: Potentially, the more time available might lead couples to reconnect at an intimate level and to improve their sexuality. However, the majority of quarantined participants experienced reduced number of SI per week, with poor household privacy and lack of psychological stimuli as cited causes, even as a majority did not report reduced autoeroticism.

Desire for parenthood at the time of COVID-19 pandemic: an insight into the Italian situation.

Purpose: To evaluate the impact of the COVID-19 pandemic lifestyle change on couples of reproductive age and on their desire for parenthood.Materials and methods: A quantitative correlational research study, based on a web survey, was conducted among Italian men and women in heterosexual stable relationships, aged between 18 and 46 years. The self-administered Italian version questionnaire was created using Google Forms and posted on chats and social networks.The mood of participants before and during the quarantine was assessed using a scale from 1 to 10 (1 = no wellbeing; 10 = total wellbeing). Couples' quality of life and their reproductive desire were evaluated.Results: 1482 respondents were included: 944 women (63.7%) and 538 men (36.3%). A significant trend toward reduced mean wellbeing scores during the quarantine, compared to before, was found (p < .01). From 18.1% participants who were planning to have a child before the pandemic, 37.3% abandoned the intention, related to worries of future economic difficulties (58%) and consequences on pregnancy (58%). Of 81.9% who did not intend to conceive, 11.5% revealed a desire for parenthood during quarantine than before (p < .01), related to will for change (50%) and need for positivity (40%). 4.3% of these actually tried to get pregnant. Stratifying by age, a trend toward older ages was found in the desire for parenthood before and during the COVID-19 pandemic (p < .05).Conclusions: COVID-19 pandemic is impacting on the desire for parenthood. It is unknown whether these findings will result in a substantial modification of birth rate in the near future.
