FertilitySCORE® kit

Hometest for male fertility potential

Infertility affects approximately 10-15% of couples of reproductive age and 40-50% of infertility is due to problems with sperm.
The FertilitySCORE® Kit allows the user to determine at his own home if a sperm sample has normal or less than normal activity. Normal activity is associated with a better chance for pregnancy.

The FertilitySCORE® kit is based on the principle that metabolically active spermatozoa will chemicaly change the structure of a color dye, resulting in a marked colour change of the dye from dark blue to pink.
If the color match is in the "Positive" group there is an 86% chance that sperm activity is normal (20 million or more active sperm per milliliter of fluid) and fertility potential is good. This does not guarantee that a pregnancy will occur because many factors, both male and female, affect fertility.
If the color match is in the "Negative" group there is an 86% chance that the sperm activity is below normal (less than 20 million active sperm per milliliter of fluid). Pregnancy is less likely but certainly not impossible. A physician should be consulted.
Each kit contains materials for 2 test. Contact us for more information on how to order this product in your region.

The FertilitySCORE® test has been CE marked according to the specifications set forth in the European Medical Device Directive 98/79/EC.
