The Relationship

Colourful ornaments often communicate salient information to mates, and theory predicts covariance between signal expression and individual quality. This has borne out among pigment-based signals, but the potential for ‘honesty’ in structural coloration is unresolved. Here, I synthesized the available evidence to test this prediction via meta-analysis and found that, overall, the expression of structurally coloured sexual signals is positively associated with individual quality. The effects varied by the measure of quality, however, with body condition and immune function reliably encoded across taxa, but not age nor parasite resistance. The relationship was apparent for both the colour and brightness of signals and was slightly stronger for iridescent ornaments. These results suggest diverse pathways to the encoding and exchange of information among structural colours while highlighting outstanding questions as to the development, visual ecology and evolution of this striking adornment.

Abstract Background: The novel beta-coronavirus disease (COVID-19) has infected millions of people globally with high risk among male then female. However, the effect of COVID-19 andrology is still a subject of dispute. We planned to analyze the overall consequences of COVID-19 on semen parameters and male sex hormones.Main text: Systematic search was performed on MEDLINE and Scopus database until June 11 2021. We included observational studies, which reported mean ± standard deviation of the semen parameters and serum sex hormones of those reproductive-aged male recovered from COVID-19 and controls who did not suffered from COVID-19. We used Random-effect model to pool the studies, as heterogeneity was present. Heterogeneity was evaluated by Q test and I2. All studies were assessed with their quality and publication bias.We assessed 966 articles for eligibility and found 7 eligible studies meeting PICO criteria. This include 934 participants with mean age 37.34 ± 10.5. Random-effect model meta-analysis showed that men recovered form COVID-19 had semen parameters less than those who had not suffered from COVID-19. The overall mean difference (MD) [95% confidence interval (CI)] in semen volume, sperm concentration, sperm number, and progressive sperm motility was -0.20 (-0.45, 0.05), -16.59 (-34.82, 1.65), -45.44 (-84.56, -6.31), -1.73(-8.20, 4.75) respectively. Considering sex hormones; Luteinizing hormone and prolactin was found more among those recovered with the significant MD (95% CI) of 3.47 (1.59, 5.35) and 3.21 (1.71, 4.72) respectively.Conclusion: Both the semen parameters and sexual hormones were found to be affected after infected with COVID-19. However, the mechanism for testicular involvement remains doubtful.This systematic review and meta-analysis has been registered in PROSPERO (ID: CRD42021259445)
