Loss of livestock breeding efficiency due to uncompensable sperm nuclear defects

Abstract excerpt

An important goal of modern analyses of semen is to elucidate the molecular traits of mammalian sperm chromatin structural abnormalities, defined here as 'uncompensable', that lead to abnormalities in fertility, pronuclear formation, early embryo quality and pregnancy outcome. Sperm with uncompensable nuclear abnormalities are able to fertilize oocytes both in vivo and in vitro; however, due to the uncompensable...
