Reduced eccDNA content in idiopathic asthenozoospermia sperm is associated with compromised DNA repair capacity and elevated DNA damage

Abstract Background Despite representing approximately 30% of male infertility cases, idiopathic asthenozoospermia (iAZS) remains etiologically uncharacterized. Extrachromosomal circular DNA (eccDNA) is mobile and circular DNA outside of linear chromosomes. Although eccDNA has been identified in hum...
