A promising sex selection method published in 2019 has been disproven by new research showing the targeted genes exist equally in both X and Y sperm. The findings underscore nature’s sophisticated mechanisms for maintaining balanced sex ratios across species.

New Study Challenges Previous Sex Selection Breakthrough

Researchers have disproven a sex selection method that initially showed promise for revolutionizing animal breeding and potentially human fertility treatments, according to a new study published in iScience. The original 2019 research suggested that targeting specific genes on the X chromosome could enable efficient separation of sperm carrying female-determining chromosomes from those carrying male-determining chromosomes.
