What results can be expected from reverse-sorted semen?

The reverse sorting process can provide samples for fertilization with approximately 87-90% accuracy of the desired sperm cells. Embryos created with reverse sorted semen have been reported on average to be up to 90% accurate on the desired gender. Although most sires will sort accurately, the process can be affected by semen quality and concentration thus resulting in variation in embryo/live calf sex ratio. There is often significant variation among sires in fertility and embryo development rates.
