Our synthesis confirms 18 genes with robust evidence for PCD-associated male infertility (ADCY10, ARL2BP, CCDC151, CCDC39, CCDC40, CDC14A, DNAAF1, DNAAF2, DNAAF4, DNAAF6, DNAH11, DNAH5, DNAI1, HYDIN, LRRC6, MNS1, RSPH3, RSPH4A, TTC12), highlighting shared pathways between somatic ciliary function and sperm flagellar integrity. This evidence concerns the gene CCDC40 and male infertility.
