The Shettles method uses the timing of conception, along with a variety of other factors, to not only predict gender, but to actually attempt to determine a baby’s gender. Understanding the guiding principles behind the Shettles method is an important part of understanding how exactly the Shettles method can be used to predict gender.
The differences that occur between the sperm that produces a boy (sometimes called “boy sperm”) and the sperm that produces a girl (sometimes called “girl sperm”) is one of the most important parts of the Shettles method. According to the Shettles method, the boy sperm are thought to be smaller, faster, and to die off quicker than the female sperm. Therefore, the timing of ovulation will greatly influence the gender of the baby. If you have intercourse around 2 1/2 to 3 days before ovulation, the Shettles method would predict that your baby’s gender would be female. This is because the boy sperm are more likely to die off in this time frame. If you have intercourse closer to ovulation, the Shettles method predicts the baby’s gender would be male.
Another important part of the Shettles method is the pH environment of the woman’s reproductive tract. The Shettles method predicts that the baby’s gender is more likely to be female if the woman’s tract is more acidic. Conversely, if the woman’s tract is more alkaline, the baby’s gender is more likely to be male. So, if a woman is hoping to have a girl, she wants to have a more acidic environment. This can be accomplished with a variety of methods. The Shettles method predicts that using a douche of water and vinegar before intercourse would help to create a more acidic environment, whereas a douche of water and baking soda would help to create a more alkaline environment, and therefore a boy. Even the position of intercourse and whether or not a woman has an orgasm during intercourse will affect the pH, according to the Shettles method, and these factors also can be used to predict gender or to determine gender.
