Staining of a microscopic native preparation with 0.5% aqueous, bluish eosin solution; counting of at least 200 spermatozoa after 5 minutes; the number of red stained spermatozoa heads corresponds to the rate of devitalized spermatozoa (with correspondingly defective cell membrane); normally below 40%. See also necrozoospermia and spermiogram.
