Fifty-four mouse testis-enriched genes are not needed for male fertility

(Baylor College of Medicine) In the male mouse, more than 2,300 genes are predominantly expressed in the testis, but their particular functions in reproduction are still a mystery. In a report published today in the Proceedings of the National Academy of Sciences, researchers from Baylor College of Medicine discovered that 54 of the mouse testis-enriched genes that are also expressed in humans are not necessary for male fertility.
