title: Differences in motility of human X- and Y-bearing spermatozoa.
abstract: Human Y-bearing spermatozoa, as identified by the quinacrine staining technique, were found to be significantly more motile than X-bearing spermatozoa under laboratory conditions. This difference is consistent with current estimates of the difference in mean head DNA content.
