Comparison of Fluorometric and Microscopic Methods of Semen Analysis

چکیده
Bulls vary greatly in semen quality, both among bulls and among ejaculates within a bull. Therefore, semen is evaluated routinely using those characteristics that are known to affect fertility. These include general appearance of the semen, volume of the ejaculate, concentration of sperm, motility, metabolic activity, percent live/dead and morphological abnormalities. The minimum levels for a sample of probable fertility include about 500 million sperm/ml, at least 50% progressively motile sperm, and 80% with normal morphology.
