Assay comet sperm

More information
High sperm DNA fragmentation is associated with reduced natural pregnancy rates and assisted conception pregnancy rates as well as live birth rates. High levels of DNA fragmentation may be reduced by considering varicocele repair, treatment of underlying infections or inflammation, changes in lifestyle, or with antioxidant supplements. This test has the ability to measure large numbers of cells between 5, and 10, sperm , rapidly in an ejaculate. It has been developed using human and animal models over the last 35 years, and is one of the most statistically robust tests available for sperm DNA fragmentation. It is a standardised, validated CLIA-approved test with high reproducibility and low variability.

All sperm DNA tests are not the same. Available tests measure different aspects of sperm chromatin damage and as a result have variable levels of diagnostic and prognostic strength Table 1. This technique is used extensively in drug toxicity research. This is due to several unique features of the assay:. Nuclear protein damage could make the DNA more vulnerable to damage, but it is not a measure of the actual damage to the DNA molecule itself.
