Volume
Milliliters (mL) of your entire sample
Volume refers to the amount of semen in your sample (measured in mL). Volume can fluctuate quite a bit depending on when you last ejaculated.
Concentration
How many million sperm per mL
Sperm concentration is the number of sperm per mL in a semen sample.
Count
How many sperm are in your sample
Sperm count is the total number of sperm in the entire sample. To determine the sperm count, sperm concentration is multiplied by the total volume of the sample.
Motility
How your sperm are swimming
Sperm motility refers to the percentage of sperm that are swimming in a sample. This is important for fertility because sperm need to swim to reach and fertilize an egg.
Total Motile Count
How many sperm in your sample are swimming
This is regarded as the most important factor for male fertility- it is the result of multiplying sample volume, concentration, and motility.
Morphology
How your sperm are shaped
Sperm morphology refers to the shape of your sperm. In typical samples, only 4%-20% of sperm cells are normally shaped. Lower-morphology sperm can still result in a pregnancy. Because of our analysis methods, we may not be able to return morphology results for samples with low sperm counts or low motility.
