SARS-CoV-2: diagnostic and design conundrums in the context of male factor infertility.

ABSTRACT: The question of whether SARS-CoV-2 (severe acute respiratory syndrome-related coronavirus-2 [SARS-CoV-2], leading to the COVID-19 infection) can be harboured in the testes and/or semen is currently unanswered. It is essential to understand the limitations of both antibody and real-time PCR tests in interpreting SARS-CoV-2 data in relation to analyses of semen and testicular tissue without appropriate controls. This article critically analyses the evidence so far on this, and the possible implications. The limitations of diagnostic tests in both sampling and testing methodologies, their validation and their relevance in interpreting data are also highlighted.

Project description:BackgroundAnogenital distance (AGD), the distance between the anus and genitals, is in rodents a well-established marker of early androgen action and has been suggested to be so in humans as well. Thus, a link between human AGD and semen quality and potentially fecundity may exist.ObjectiveThe aim of this study was to assess the association between AGD and male factor infertility and among proven fertile men also time to pregnancy (TTP).Material and methodsAll included men were recruited from and examined at Copenhagen University Hospital - Rigshospitalet, Denmark (N = 388). Men with impaired semen quality were included from infertile couples (N = 128), and men with naturally conceived pregnant partners were invited to participate when their partners had their routine second trimester examination (N = 260). All men underwent a physical examination, completed a questionnaire (including TTP for the fertile men), delivered a semen sample and had a blood sample drawn. The primary exposure was AGDAS measured from the centre of the anus to the posterior base of the scrotum. Associations between AGD and fertility status as well as between AGD and TTP among the fertile men were calculated using multiple logistic regression adjusted for covariates.ResultsAGD did not show a statistically significant association with fertility status. In adjusted logistic regression models, the odds of infertility per 1 cm increase in AGDAS were 1.02 (95% confidence interval [CI]: 0.88; 1.19). Among fertile men, a 1-cm increase in AGDAS was associated with an 8% non-statistically significantly reduced odds of having a longer (>3months) TTP (adjusted odds ratio (OR) = 0.92, 95% CI: 0.76-1.11).ConclusionOur study showed that the clinical application of AGD as a predictor of fertility and fecundity seems to be limited as no associations were observed between AGD and fertility status, nor was the decreased risk of experiencing a longer TTP with longer AGDAS statistically significant.
