What information does a semen analysis provide?

The main parameters that are examined during a semen analysis include the volume, concentration, motility and morphology (shapes) of sperm. These numbers are then used to formulate the clinically-significant parameter called the total motile count which is the quantification of “how many moving sperm are in the ejaculate” (normally only a percentage of sperm are moving). Even more insight can be gained in measuring how many sperm are progressively motile (physically propelling forward vs swimming in place). Reference ranges for a semen analysis are based upon men from around the world who have successfully sired a child. It is important to understand that a single semen analysis does not necessarily provide the complete picture about fertility potential. Semen quality can fluctuate from day to day and the main parameters listed above do not fully represent the true potential of sperm to fulfill their required contribution to healthy embryo creation.
