The Shettle’s Method

Reviewed by Dr. Shawn A. Tassone, OB/GYN

The Shettle’s 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 in this method and can’t work without it. Also, keep in mind that while Shettle’s may have positive results in the initial trials, it is very labor intensive and there is no guarantee even under perfect circumstances. We will dig into the concepts of this theory and separate the boys from the girls.

Boys

Since boy sperm are faster and have a shorter lifespan, the Shettle’s Method suggests timing intercourse as close to ovulation as possible. The concept of this is that the boy sperm will be faster to the egg increasing the odds. 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 4-5 days prior to ovulation so try to time properly by tracking your cycle over the course of a couple months.

Girls

Girl sperm is slower but can last longer in the cervical mucous that’s extremely thick about 4-5 days before ovulation. The concept is to time intercourse during this part of the cycle to produce girls since the X chromosomes can withstand the mucous and travel up to the egg at its leisure. The missionary position is recommended along with shallow penetration. Women should avoid orgasms unfortunately. PH acidity levels are high at this point, and girl sperm and known to live longer during this period.
