Sperm count non motile motility normal

Spermatozoa, after passage through the epididymis, are motile cells. Sperm motility becomes critical at the time of fertilization because it allows or at least facilitates passage of the sperm through the zona pellucida. Without technologic intervention, a non-motile or abnormally-motile sperm is not going to fertilize. Hence, assessing the fraction of a sperm population that is motile is perhaps the most widely-used measure of semen quality. In evaluating motility with most species, sperm are classified as non-motile, progressively motile or non-progressively motile.

Sperm Motility | Understand your Semen Analysis

In this article, we look at the impact of sperm motility on fertility, as well as the causes of poor sperm motility, and what can be done to improve it. Progressive motility refers to sperm that are swimming in a mostly straight line or large circles. Non-progressive motility refers to sperm that do not travel in straight lines or that swim in very tight circles. For the sperm to get through the cervical mucus to fertilize a woman's egg, they need to have progressive motility of at least 25 micrometers a second. Poor sperm motility or asthenozoospermia is diagnosed when less than 32 percent of the sperm are able to move efficiently. Worldwide, around 60 to 80 million couples are affected by infertility , and the rates vary from country to country.

Sperm and Semen Testing and Evaluation

A semen analysis plural: semen analyses , also called " seminogram " [1] evaluates certain characteristics of a male's semen and the sperm contained therein. It is done to help evaluate male fertility , whether for those seeking pregnancy or verifying the success of vasectomy. Depending on the measurement method, just a few characteristics may be evaluated such as with a home kit or many characteristics may be evaluated generally by a diagnostic laboratory.
