Results of gene set enrichment analysis of genes involved in reproduction.

Gene set enrichment test was conducted in edgeR using the roast function [70]. Prop.Down and Prop.Up give the proportion of genes that are down- and up-regulated. The direction of change is determined from the significance of changes in each direction and is shown in the Direction column. The P-value provides evidence for whether the majority of genes in the set are DE in the specified direction. The genes (N = 56) were selected based on [76–79].
