Shettles Scorecard

The Shettles book claims "30 years of consistent success", but what's the real score?

The scorecard results are based on the outcome of nearly 700 women (see Survey Results: Timing Analysis) who were reasonably sure they knew both the day of ovulation and the day of intercourse.

Although the results show a slight increase in girl conceptions 3 days before ovulation, and a slight increase in boy conceptions at ovulation, it is not close to Shettles' claim of "at least a 75% chance of having a child of the desired sex", and certainly a far cry from the claim that "some researchers have reported success rates up to 90%!" on the book's cover.

 ClaimedActualGrade
Shettles for a GIRL 75%65%C-
Comments: Intercourse 3 days before ovulation does show a noticeable increase over the natural odds of about 50%. However, intercourse on other days (2 or 4 days) before ovulation does not show any greater chance of having a girl.
Shettles for a BOY 80%60%D
Comments: Intercourse on the day of ovulation increases the chance of a boy somewhat.
Fertility for a GIRL D
Comments: All Shettles recommendations for conceiving a girl hamper fertility, making it harder to get pregnant at all. Attempting Shettles for a girl may take many more cycles to get pregnant, or not at all.
Fertility for a BOY A+
Comments: All Shettles recommendations for conceiving a boy lead to optimum fertility. Following Shettles for a boy should lead to pregnancy as soon as possible (assuming there are no fertility problems).
