(A) Volcano plot of DEGs between asthenozoospermia infertility and normal groups. Black dots represent genes that are not significantly differentially expressed. Green and red dots indicate significant up-regulated and down-regulated genes (|log 2 fold change| ≥ 1.0 and P value ≤ 0.05), respectively. (B) Heatmap of DEGs between asthenozoospermia infertility and normal groups. Row and column were used to represent DEGs and samples. R: asthenozoospermia infertility; Z: normal. The color scale represented the expression levels of DEGs.
