Sperm DNA Fragmentation Assay (SDFA™)檢查
可檢驗不正常精蟲
高達20%男性顯示不正常SDFA精蟲
綠色marker顯示正常 DNA精蟲
橘色marker顯示不正常DNA片段精蟲

One method to test for broken DNA (fragmentation) inside the sperm is to use the fluorescent dye acridine orange to paint sperm with normal DNA green and those with broken DNA a bright orange-red color. The photo on the right shows that routine microscopic evaluation cannot show the difference and that the dye is necessary to expose sperm with broken DNA.
