    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.

    Abstract: A validation test piece is for validating a bio-sample detection device, which includes an insert port for insertion of the validation test piece and a detection module. The validation test piece includes a base seat, a test element, a standardized data and a top cover. The base seat includes a seat body and a receiving member disposed on the seat body. The test element is connected to the receiving member, and includes a test region to be detected by the detection module. The standardized data corresponds to a sample number of the test region. The top cover is connected to the base seat for covering the test element.
