Effect of long-term storage on deoxyribonucleic acid damage and motility of sperm bank donor specimens

The percentage of sperm DNA damage in samples from sperm bank donors was not significantly different ( P =.17), whereas the percentage of motile cells was lower ( P =.009) after long-term (9–13 years) compared with short-term (1–5 years) storage. Density gradient isolation reduced the difference in...

Description
Summary:The percentage of sperm DNA damage in samples from sperm bank donors was not significantly different ( P =.17), whereas the percentage of motile cells was lower ( P =.009) after long-term (9–13 years) compared with short-term (1–5 years) storage. Density gradient isolation reduced the difference in sperm motility between the two groups.
