A method of sorting living cells based on DNA content. Mammalian sperm subpopulations enriched in X- or Y-sperm. X- and Y-enriched sperm-plasma- membrane vesicles. Substantially pure sex-associated membrane (SAM) proteins. Antibodies'binding to X- or Y-SAM proteins, essentially free of antibodies binding to Y- or X-SAM proteins respectively, or to the H-Y antigen. Semen samples enriched for X- or Y-sperm. Methods for increasing the probability that offspring will be male or female comprising the step of allowing a sperm from an enriched semen sample to fertilize an ovum. Methods for increasing the probability that offspring will be male or female comprising the step of immunizing a female with X- or Y-SAM proteins. Methods of decreasing fertility comprising the step of immunizing a female with both X- and Y-sperm. Methods of increas- ing the probability that mammalian offspring will carry a gene for a particular sex-chromosome linked trait. |
