The interest in sex selection of a particular individuals comes from the ancient greeks, but the study on effective methods of this selection is relatively new. Know future progeny sex brings to market great potential for genetic improvement. Sex selection contributes to cattle for animal optimization of desired sex, to human, preventing diseases sex-linked, or even sex selection of wild animals in captivity. With the biotechnologies advent such as artificial insemination and embryo transfer, sexing begins to have relevance in current scenario and benefit costs will be significant. Several techniques have been developed aiming the best preselection of sex, such as immuno separation, density gradient, and flow cytometry that in current world scenario is the technique with best results and only one that allows comercialization of sexed semen. Sexing processes still require many studies due to damage to sperm cells during the separation process, compromising fertility results. This literature review comes as a tool for understanding the sexing process and techniques used.
