The Pre Conceive Plus Male Fertility Test is an easy-to-use home test kit to measure your sperm concentration. It is the #1 Home FDA Approved Test for determining a male fertility condition. The test determines whether your sperm concentration is above or below 20 million sperm cells per milliliter (million/mL). Two test results with sperm concentration of less than 20 million/mL can alert you to possible male fertility issues. The Pre Conceive Plus Male Fertility Test works by staining the cells in a sperm sample to produce a color. The intensity of this color is then compared to a color reference on the FertilMARQ test cassette. The color comparison will tell you whether the sperm concentration in the test sample is above 20 million/mL (a positive test) or below 20 million/mL (a negative test). Taking the male fertility screening test will indicate if you have a low amount of sperm in your semen. You can provide these test results to your physician to aid in determining male fertility conditions. The Pre Conceive Plus Male Fertility Test Kit Includes: Test Cassettes (2 Tests), One Bottle of Blue Solution and One Bottle of Clear Solution, Two Plastic Droppers, Two Liquefaction Cups with Lids, Two Non-Spermicidal Condoms and One Instruction Booklet.
