Male mice homozygous for a knock-out allele show a marginal reduction in fecundity associated with oligozoospermia, various histopathological changes in the male reproductive tract tissues as well as in non-reproductive tissues, and a lower bacterial clearance capacity in response to uropathogenic E. coli infection.
