Semen Analysis Overview
In cases of infertility, the man is a contributing factor in approximately 50% of cases. A semen analysis is conducted to test a man’s sperm count (concentration), moving sperm (motility), normally shaped sperm (morphology), and other parameters. One of the most important factors in achieving a pregnancy is the number of motile sperm in the sample. If the sperm cannot swim to the egg, natural pregnancy is not possible. The YO Home Sperm Test analyzes your motile sperm concentration (how many are moving) and sperm quality (YO Score) and compares your results to laboratory standards and to other men who have fathered children. You will also receive a video recording of your sample as part of the YO Test. Here is some more detail on each result and the reference ranges for normal vs. abnormal:
YO Result #1: Motile Sperm Concentration (MSC)
Sperm cells need to move forward to reach the egg during natural conception. YO first reports whether your motile sperm concentration (MSC) is above or below a “normal range” of six million motile sperm per milliliter. The “normal range” of six million motile sperm is calculated by multiplying the World Health Organization (WHO) reference value for sperm concentration (15 million) times the normal reference range for sperm motility (40%). 15 million x 40% = 6 million. Although only one sperm cell is needed to fertilize an egg, 6 million motile sperm per milliliter is the cut-off or “threshold,” which determines the results of Low vs. Moderate/Normal MSC.
YO Result #2: YO Score Quality Ranking
YO Score is a ranking of your motile sperm concentration (MSC) compared to other men who have fathered children. The result is 10 to 90 in intervals of 10. If your score is 20, you rank above 20% of fathers. If your score is 90, you rank above 90% of fathers. The higher your YO Score, the more likely you are to achieve a pregnancy in a shorter amount of time. YO Score is a reliable tool for monitoring MSC changes over time and the cornerstone of the fertility improvement tools contained in the YO Application.
YO Result #3: Video of Your Sample
As part of the YO Home Sperm Test, you will receive a recorded video of your sample. The video offers a clear visual reference to complement your MSC and YO Score results. Videos are available for sharing with an expert, family, or friends if desired or kept 100% private inside the app for personal viewing.
