The amount a man ejaculates is also assessed. 2ml or more is the normal volume for ejaculate. There are a number of factors that can affect how much ejaculate is provided for a semen analysis. If not all of the ejaculate is collected in the provided container or if a man gets “performance anxiety”, the amount of semen collected may be less than what the man actually produces.
The seminal fluid will be tested to determine the fluid’s colour, the viscosity and how long it takes for the semen to liquefy after ejaculation. All of these aspects can have a negative impact on the sperm.
Total Motile Count
This is the final assessment. It calculates the total number of motile sperm in a man’s ejaculate. Your fertility specialist will multiply the following: the volume of your sample X the sperm count X the percentage of motile sperm. An acceptable ejaculate should have more than 40 million motile sperm.
White Blood Cells
If there is a higher number of white blood cells in the semen, then it may indicate a past infection or possibly inflammation. There should be some white blood cells in the semen. A sample containing more than a million white blood cells per millilitre is considered to be problematic. If elevated levels of white blood cells are found, additional samples will need to be tested for white blood cells.
An evaluation is done to determine how much progress motile sperm are able to make. Motility does not guarantee forward progression. A clear picture of just how active sperm are needs to be obtained. By combining the percentage of motile sperm with the distance they are able to swim, your fertility specialist gains a better idea of how well your sperm perform.
