Abstract
The invention allows the production by centrifugation in density gradient, in companies specialized in the production and commercialization of frozen semen, of semen doses enriched with X or Y chromosome-bearing spermatozoa, not impairing the fertilization capacity of said spermatozoa. According to the present invention, samples of spermatozoa containing both X and Y spermatozoa can be separated to produce subpopulations enriched with X or Y spermatozoa, which are substantially pure regarding the desired spermatozoa and substantially free from the other type of spermatozoa.
