Explain sperm tests norm forms motility

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.

What is a sperm morphology, and what do results mean?

Sperm morphology — the size and shape of sperm — is one factor that's examined as part of a semen analysis to evaluate male infertility. Sperm morphology results are reported as the percentage of sperm that appear normal when semen is viewed under a microscope. Normal sperm have an oval head with a long tail. Abnormal sperm have head or tail defects — such as a large or misshapen head or a crooked or double tail.

Sperm are male reproductive cells present in the ejaculate. A doctor can tell someone their sperm count using a test called semen analysis. The average sperm count is between 40 million and million sperm per milliliter. This number can vary between testing centers, with the above range coming from Resolve , a nonprofit fertility association. A doctor may recommend a semen analysis for many reasons, such as to test for possible underlying causes of infertility , how well the reproductive organs are working, or whether a surgical procedure for sterility was successful.
