From: DNA fragmentation index (DFI) as a measure of sperm quality and fertility in mice
Comparison of fresh sperm motilities and DFI of frozen-thawed sperm in a group of mutant males with normal fertility (n = 24) and that in a group of mutant males with impaired motility (n = 17). P < 0.0001 between bars with the same symbol ➀ or ➂, and P < 0.001 between bars with the same symbol ➁.
