Two hundred and thirty-three novel human reproductive tract-specific genes that each have mouse orthologous genes but with no reported knockout mouse models. The listed genes were identified in one or more datasets as indicated in the Venn diagram. Underlined genes were also identified in our studies as reproductive tract-specific in mouse (109 genes). Genes written in blue encode either enzymes, kinases, GPCRs, oGPCRs, transporters, transcription factors, or proteins involved in epigenetic regulation (74 genes). Genes written in dark red were identified in both testis (testis and/or testis cell) and epididymis (10 genes).
