Sperm deoxyribonucleic acid fragmentation dynamics in fertile donors Jaime Gosálvez, M.D., Elva Cortés-Gutierez, Ph.D., Carmen López-Fernández, Ph.D., José Luís Fernández, M.D., Pedro Caballero, M.D., Rocio Nuñez, M.D. Fertility and Sterility Volume 92, Issue 1, Pages 170-173 (July 2009) DOI: 10.1016/j.fertnstert.2008.05.068 Copyright © 2009 American Society for Reproductive Medicine Terms and Conditions

Figure 1 (a) Box-and-whisker plots for the sperm DNA fragmentation index observed at different incubation times (37°C) for spermatozoa and the rate for sperm DNA fragmentation observed at each interval. (b) Average sperm DNA fragmentation observed at different incubation times (blue line) and adjustments for logarithmic (red line), linear (gray line), or exponential (green line) functions. The corresponding equations are shown with the same color pattern. The pink line (donor 7) shows the maximum R2 value for a logarithmic function, and the light-green line (donor 15) shows the maximum R2 value for an exponential function. VsDF = velocity of sperm DNA fragmentation.
