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 sperm motility between the two groups.
