Tests for fertility in males and females
The Test-Point Kit allows you to determine if a sperm sample has normal or less than normal
activity. Normal activity is associated with a better chance for pregnancy.
The male must produce a sufficient number of normal, actively moving sperm in order to
achieve conception and according to the World Health Organisation a man needs 20 million
sperm per mL to be considered fertile. The Test-Point Test Kit will tell you whether the
sperm concentration in the test sample is below 20 million/mL motile sperm negative test
or above 20 million/mL motile sperm positive test.This test can help to identify the potential
of male fertility in the privacy of your home.
