A simpler way to choose the sex of offspring by separating X and Y sperm

A simple, reversible chemical treatment can segregate X-bearing sperm from Y-bearing sperm, allowing dramatic alteration of the normal 50/50 male/female offspring ratio, according to a new study. The study was performed in mice, but the technique is likely to be widely applicable to other mammals as well.
