Semen Sexing: Technique, Scope, and Constraints

, 2022
The practice of sexed semen in livestock production and genetic improvement has shown to be achievable with variable degrees of efficiency during several species and proved to be economically viable in cattle. Sexed semen is a reproductive technology intended to change the sex ratio of the offspring toward a preferred gender.
