Can I use the YO Home Sperm Test for Post-vasectomy testing?

The YO Home Sperm Test is optimized for fertility testing and reports motile sperm values above and below 6 million per milliliter. To avoid unwanted pregnancy after a vasectomy, you want to have a sperm concentration/motility of ZERO. Currently, YO does not give a value of ZERO and is therefore not recommended for post-vasectomy testing.
