The Sperm DNA Fragmentation Test is a laboratory test used to assess the integrity of the genetic material within sperm cells. It measures the level of DNA fragmentation, which refers to breaks or damage in the DNA strands. The test is typically performed by isolating sperm cells from a semen sample and subjecting them to a specific laboratory technique to evaluate the extent of DNA fragmentation. The results of this test can provide information about the potential fertility of an individual and may help guide appropriate treatment options.
