The Shettles Method

The Shettles Method is a theory that attempts to increase the odds of having a boy or girl by timing intercourse with a women’s ovulation date, use of sexual positions, and depth of male penetration. The logic behind this is that X or Y chromosomes will be offered different advantages in being able to reach the egg. Predicting ovulation is essential to this method. Also, keep in mind that while Shettles may have yielded positive results in anecdotal accounts, it is very labor intensive, and there is no guarantee that it will work even under perfect circumstances. We will dig into the concepts of this theory and separate the boys from the girls.

Boys

Since “boy sperm” (the ones carrying Y chromosomes) are faster and have a shorter lifespan, the Shettles Method suggests timing intercourse as close to ovulation as possible. The idea behind this is that the boy sperm will get to the egg faster, increasing the odds of a boy. Women should try to orgasm at the exact same time as the man, since there will be more fluids mixing around during the deepest penetration. It’s not a good idea to have intercourse for four to five days prior to ovulation, so try to time properly by tracking your cycle over the course of a few months.

Girls

“Girl sperm” is slower but can last longer in the cervical mucous, which is extremely thick about four to five days before ovulation. The idea is to have intercourse during this part of the cycle to produce girls, since the X chromosomes can withstand the mucous, enabling the sperm to travel up to the egg at its leisure. The missionary position is recommended for this, along with shallow penetration. Women should also avoid having orgasms, unfortunately. PH acidity levels are high at this point, and girl sperm are known to live longer during this period.
