<unk>  is a means of choosing what type of<unk>  cell is to fertilize the egg cell. Several conventional techniques of centrifugation or swim-up. Newly applied methods such as flow cytometry expand the possibilities of<unk>  and new techniques of<unk>  are being developed. It can be used to sort out<unk>  that are most healthy, as well as for determination of more specific traits, such as sex selection in which<unk> atozoa are separated into X- (female) and Y- (male) chromosome bearing populations based on their difference in DNA content. The resultant 'sex-sorted'<unk> atozoa are then able to be used in conjunction with other assisted reproductive technologies such as artificial insemination or in-vitro fertilization (IVF) to produce offspring of the desired sex - in farming animals but also in human medical practice.
