Semen Analysis

Semen analysis is the most efficient and inexpensive way to study male fertility. It is usually the starting point for a male infertility evaluation. It includes a study of sperm concentration, a motile sperm count (mobility), and study of sperm morphology (shape).

Lower sperm concentration and sperm motility affect the motile sperm count, which is a measurement of the sperm concentration that moves to the egg site to fertilize the egg. Sperm count is a measurement of how many million sperm there are in each milliliter of fluid. Normal sperm concentration is 15 or greater million per milliliter.

Sperm morphology is important as well because it reflects the ability of the sperm to fertilize an egg.
Sperm morphology test describes the shape of the sperm. Sperms are stained by Diff-quick stain that compound Methanol, Eosin, and Methylene blue. After that the sperm are examined under a CASA (Computer Asisted Semen Analysis) and must meet specific sets of criteria for several sperm characteristics in order to be considered normal.
Sperm morphology test show two normal values of semen analysis specified by two different standards: WHO standard and Strict Criteria. The normal value is 4% according to WHO and 14% according to Strict Criteria.
