A sperm analysis test is one of the first tests conducted to detect male fertility problems, the test is done by examining the quality and volume of a man’s sperm. Semen analysis is a lab evaluation of a semen sample collected by a man masturbating. Sperm counts vary daily so in some scenarios multiple samples over the course of a few weeks may be requested to verify the results. In addition to the detection of fertility problems, a sperm analysis can also be used to determine whether or not a vasectomy was successful. The research-based methods to test and handle the semen in a specialized lab ensure patients obtain accurate results. Labs used for sperm analysis perform a high volume of semen analyses and/or are part of a fertility clinic. When the sperm analysis is conducted to test male fertility it examines the semen volume, the pH level to determine whether the semen is too acidic which can adversely affect sperm health, the number of sperm per millimeter of semen to determine sperm concentration, and the ability of the sperm to swim toward an egg to determine mobility. Analysis also helps test the size, and shape of the sperm, signs of inflammation or infection, sperm vitality by assessing the percentage of live sperm in the sample, and how long it takes for semen to change from a sticky substance to a liquid.
