The FertilityScoreTM male fertility test will tell you whether the sperm concentration in the male fertility test sample is below 20 million/mL motile sperm (negative test) or above 20 million/mL motile sperm (positive test). The World Health Organization standard for a fertile male is above 20 million/mL motile sperm. The FertilityScoreTM Home Screening Test is also unique in that is uses the whole sample to determine male fertility. Other tests use only a small portion of the ejaculate which can lead to inaccurate male fertility test results due to clumping and cellular debris in the sample. You may have 60 million/ml sperm, but if the motility is 0% then the FertilityScore results will read negative. A key element to male fertility is the number of motile (live) sperm. FertilityScore's ability to differentiate motile from non-motile sperm is a unique feature of these kits.
