The Shettles Method is a conception prediction theory developed by biologist Landrum B. Shettles in the 1960s that claims to detemine the sex of your baby. The theory is based on female (X) sperm being slower but stronger than male (Y) sperm. The theory also suggests that male (Y) sperm are harmed in acidic environments. While this theory is often debated, it is typically considered more reputable than many old wives tales.
Instructions
1. Select a method to track your ovulation. You can track your basal body temperature to find the spike just before ovulation, use purchased ovulation tests, count fourteen days prior to the start of your next period, or any other method you like. Many reliable ovulation prediction methods can be found with a simple Internet search.
2. Track your ovulation cycle on a calendar for easy reference.
3. Avoid having sexual intercourse two to three days before ovulation is expected. Since female sperm have a longer life than male sperm, the female sperm are more likely to still be present when ovulation occurs, and the male sperm are more likely to die before ovulation.
4. Have sexual intercourse as close to ovulation as expected, but not more than one day prior. The quicker male sperm will reach the egg before the slower female sperm.
5. Achieve deepest penetration when having sexual intercourse. Acidic environments harm male sperm, and the uterus opening is the least acidic area.
