Can the Billings Ovulation Method™ be used to choose the sex of my baby?
The scientific evidence on this is controversial, however anecdotal evidence tends to indicate that an act of intercourse early in the development of the characteristic mucus (when the sensation first becomes slippery) is more likely to result in a girl, while an act of intercourse on the Peak day or the day after is more likely to result in a boy. A study in Nigeria appeared to confirm this tendency: success in pre-selection of a boy was achieved by 310 couples, failure in pre-selection of a boy occurred in four couples. Success in pre-selection of a girl was achieved in 90 couples, failure in pre-selection of a girl occurred in two couples. Pre-determination of the sex of a baby is never likely to be 100 percent reliable.
