Abstract
Disclosed herein are methods for the detection of the presence of sperm DNA fragmentation in a semen sample. The methods include embedding of sperm cells of the semen sample in a gel, denaturing DNA of the sperm cells, and lysing the nuclear proteins of the sperm cells. The present method includes an ionic surfactant sodium dodycyl sulfate (SDS) and a chaotropic agent urea in the lysis solution for releasing DNA from protamine of chromosome, which significantly reduces the time required for lysis. A kit for detecting sperm DNA fragmentation in a semen sample is also disclosed.
