Which tests are performed?
Semen anaylsis of your sample will look for a number of factors including:
Appearance: what the sample looks like.
Volume: How much sample there is. After two days abstinence there should be more than 1.5ml of semen.
Liquefaction: When semen is produced (ejaculated) it coagulates on contact with the air, then, over a short period of time, it liquefies.
Viscosity: This is a measure of how fluid the sample is (for example, water has a low viscosity, treacle has a high viscosity.) Semen should have a fairly watery consistency at the time of testing (within one hour after ejaculation.)
pH: The pH of a substance is a measure of how acid or alkaline it is (pH 7.0 is neutral.) The pH of semen increases with time but should not be less than 7.2 at one hour.
Motility: This measures what percentage of sperm are moving and how well they are moving.
Sperm count: This is a measure of the total number of sperm (spermatozoa) are present in your sample. It is usually recorded in millions of sperm per ml of semen. A normal count is greater than 15 million per mL
Agglutination, MAR test: Used to assess immunological causes for male infertility.
Volume, pH, viscosity, appearance, debris, leukocytes: provides indication of male accessory gland infection, inflammation, dysfunction, obstruction.
