Shettle Method
BABY GIRL
- Have lots of sex starting 3 days before ovulation (more frequent ejaculations means fewer Y-sperm, and the longer sperm wait for the egg, the better the odds that the stronger female sperm will be the last woman standing)
- Avoid female orgasm, which will only help the weaker male sperm along
BABY BOY
- Avoid intercourse until the day of ovulation (this way the faster-swimming boy sperm won't be kept waiting fot the egg )
- Achieved female orgasm
- Have the male partner drink something caffeinated an hour before intercourse (to speed up his boy-making boy)
