Figure 6 shows cytograms of a patient over a nine month period. There is very little fragmentation in months 2 and 3; however, in month 4 he had injured his back and required an injection of cortisone. The sperm DNA fragmentation increased to about 50% before returning back to the pre-treatment period.
