From: DNA fragmentation index (DFI) as a measure of sperm quality and fertility in mice

The linear correlation between DFI of frozen-thawed sperm and % of sperm with normal tail morphology. Pearson r = −0.9376, P < 0.05. Total n = 60. Normal sperm tail percentages were divided into 10–20%, 30–50%, 51–60%, 61–70% and 81–95 for measuring the correlation.
