No definitive answer: There is no definitive answer, and thus why you are "lost with differing answers." ericsson methods can never fully extrapolate 100% sperm for male or female, ...The layers of gender-selected sperm are of higher concentrations but not pure. This lack of purity explains the approximate 30% chance of gender selection failure of the ericsson method.
