Abstract
The sperm count of a specimen of sperm is measured by exciting the specimen with a beam of substantially monochromatic light, then measuring the intensity of the intrinsic native fluorescence emitted or the scattered light from the specimen, and then determining the sperm count using the intensity measurements. The motitily of a specimen of sperm is determined by exciting the specimen with a beam of substantially monochromatic polarized light, then measuring the intensity of the parallel and perpendicular components of the intrinsic native fluorescene emitted or the intensity of the scattered light from the specimen at a predetermined wavelength; and then determining the motitily using the two intensity measurements with parallel and perpendicular polarizations.
