Semen plays a crucial role in carrying sperm through the reproductive tract. Producing the right amount means giving sperm the best chance at reaching the egg for fertilization.

Sperm concentration is the number of sperm per milliliter of semen, as measured by a computer-assisted semen analysis device. We can use your sperm concentration and your semen volume to determine your total sperm count.

Motility is the percentage of your sperm that are moving properly. In order to fertilize an egg, your sperm must be “swimming,” so motility is an important parameter for fertility.

Our report breaks down the number of sperm with progressive motility — moving forward or in large circles — vs. sperm that are swimming in tight circles, known as non-progressive motility.

This metric is a calculation that includes sperm volume, concentration, and motility.

Because this parameter represents multiple sperm quality metrics, it's the best number we have to help us understand overall fertility and chances of conceiving with or without medical intervention.

Morphology is the percentage of sperm that are normally shaped. A sperm’s structure affects its ability to reach and fertilize an egg, and abnormalities may indicate poor sperm development or genetic issues.

Fun fact: most sperm are abnormally shaped. Morphology as low as 4–14% is totally normal.

The integrity of the DNA carried by sperm is an important factor in your ability to create a healthy pregnancy. and child. Age, illness, and lifestyle factors can cause damage this genetic material, called DNA fragmentation. This test measures the percentage of your sperm that contain damaged or fragmented DNA.

Sperm DNA fragmentation testing is not included as part of a routine semen analysis, but even those with normal results on a standard analysis may have elevated DNA fragmentation.

Legacy offers the only clinically validated at-home option for DNA fragmentation testing.
