Effect of freezing on sperm nuclear dna

WebPossible Causes of Sperm DNA Damage Following Freezing–Thawing Several mechanisms have been proposed to explain the cause of sperm DNA damage in frozen-thawed semen. It is plausible that intracellular ice crystal formation could alleviate abnormal DNA⁄nuclear protein interac-tions, resulting in sperm DNA damage (Royere et al. 1991). WebVitamin E supplementation in semen-freezing medium improves the motility and protects sperm from freeze-thaw–induced DNA damage

WebThese results indicate an effect on DNA, diminished accessibility for Feulgen, and a decrease in nuclear surface area and prompt us to hypothesize a relationship between an “overcondensation” state for sperm chromatin after freezing-thawing and a lower conception rate for human semen after cryostorage. WebThe results showed that freezing only slightly affected sperm DNA stability but significantly increased the percentage of damaged nuclei. This result differed from that of a later report on a different species by Zilli et al.
