An AgTech startup in New Zealand, Engender Technologies has created a new microfluidic and photonic technology to sort livestock sperm by sex to enrich X chromosome-bearing bull sperm cells.
The new technology uses lasers to orient sperm cells and look inside those sperm cells as well as separate them based on the presence of an X or a Y chromosome. In contrast to the industry’s standard practice of using an electric charge and field in the artificial insemination process, Engender’s technology uses a wavelength of light to sort cells-on-a-chip. The company believes this will reduce the negative impact on the fertility rate of sperm cells sorted through its system and give dairy farmers great control over offspring.
