Abstract:Sperm routinary fitness evaluation is not sufficient to predict bull reproductive capacity as they present differences in fertility up to 40%. Among the defects which compromise spermatozoa functionality, new approaches consider the study of sperm chromatin, which is the core structure containing paternal genetic information. Sperm chromatin needs to be compacted to maintain the integrity of DNA, which occurs by binding nucleoproteins with high affinity to DNA. In the last stages of sperm maturation, chromatin… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
