Association of hypoxia and oxidative stress coding genes with sperm-specific long noncoding RNAs (lncRNAs). Protein-coding genes related to hypoxia and oxidative stress were retrieved from the Gene Ontology Resource, and their neighboring sperm-specific lncRNAs were assessed by Python programming language, transferred to STRING database, and visualized via Cytoscape. The protein-coding genes are represented by circles with a color range from blue to purple. Sperm-specific lncRNAs are indicated by gray circles. Neighboring lncRNA–coding gene pairs are indicated by bolded yellow circles.
