I found this to be very interesting (read it in Nature):
...the fact that negatively charged sperm have the most intact DNA(C. Ainsworth et al. Hum. Reprod. 20, 2261–2270; 2005)...It is not known why negatively charged sperm have the most intact DNA. Researchers think that negatively charged sialic acid, added during the final stages of sperm production, is an indicator that the sperm has successfully assembled and matured. "It's like the cherry on the cake," says John Aitken, one of the researchers who developed the technique. "Everything else has to have gone absolutely normally for the sperm to get to that point."
So Negative is good!
At lab right now, trying to get that darned sample to work properly.
