we tried the GDC experiments again.
Semen ph was 9, 6 drops of lime brought it to 6, and killed nearly half of the swimmers.
we did the GDC on low for 20 min, no seperation, on high for 15 min very little seperation, all swimmers were dead.
Dh wants to try on high for 20 min as he thinks that the length of time was what went against us for the life of the sperm as that on high in the centrifuge it would have seperated.
I'm not sure what plan b is
