How does a sperm test work?

In order to test your semen, your doctor will ask you to provide a semen sample. Normally, you ejaculate into a collection cup in a room at your doctor’s office. The sample is then assessed under a microscope, which will give useful information about the specific functions of your sperm cells (i.e. the likelihood of a sample resulting in a pregnant partner). Normal sperm tests track the volume (amount of semen), concentration (how many sperm cells you have per milliliter of semen), motility (the amount of moving sperm cells), and total motile sperm count (the total amount of moving sperm cells in one ejaculate). Some sperm tests additionally assess features like morphology (the appearance of sperm cells), pH, color, the presence of other cell types and liquefaction time.

The ExSeed Home Sperm Test provides you with: Volume, concentration, motility and the total motile sperm count, which is similar to what many clinics assess. This is because the total motile sperm count is the one number that has been most highly associated with chance of pregnancy (1).
