they are not talking about the same kind of swim up that we do. this is swim up for ivf. the swim up we do uses high pH for sex selection. What they are saying is swim up for ivf does not favor any kind of gender. and this is true because swim up for ivf uses a pH of about 7 for there album.
however, there are studies out there that say what we do doesn't work. I only post the studies that say they do work and at the top I add that disclaimer.
