What?

We know, we know—there's a lot of new lingo. Whether you've never thought much about your swimmers before or you've gone down all of the internet rabbit holes, your Fellow results will be easy to understand. You'll get a breakdown of all of the most important sperm health metrics, as defined by the World Health Organization and men's reproductive health experts. This includes Total Motile Count (the best indicator of overall fertility), ejaculate volume, sperm count, motility, and morphology.
