Figure 3From: Newcastle disease virus induces testicular damage and disrupts steroidogenesis in specific pathogen free roostersPlasma concentrations of testosterone and luteinizing hormone and expression of their receptors in the control and NDV infected white leghorn roosters. Plasma levels of steroids were determined by enzyme-linked immunosorbent assay and expression analysis were performed by qPCR. Data are presented as mean ± standard deviation. The data were analysed by two-way ANOVA test, with challenge and time points as the main effects.Back to article page
