The Shettles Method: Can You Influence Your Baby's Gender?
Using timing, pH levels, and biological science to plan for a boy or girl in 2026.
Long before pregnancy symptoms begin, many couples look for ways to influence whether they will have a son or a daughter. The Shettles Method, developed by Dr. Landrum Shettles in the 1960s, remains the most popular natural strategy for gender selection today.
The Science of X and Y Sperm
The core of this method lies in the differences between sperm carrying the X (female) chromosome and the Y (male) chromosome:
- Y Sperm (Boy): Faster swimmers, but smaller and more fragile. They prefer an alkaline environment.
- X Sperm (Girl): Slower but hardier and more resilient. They can survive longer in the acidic environment of the vagina.
How to Conceive a Boy
To favor the fast-swimming Y sperm, Shettles recommends:
- Timing: Have intercourse as close to the moment of ovulation as possible.
- Environment: An alkaline environment is key. Dr. Shettles suggested that female orgasm can help by increasing alkalinity.
- Position: Deep penetration is recommended to deposit sperm closer to the cervix, where the environment is less acidic.

To favor the resilient X sperm, the method suggests:
- Timing: Have intercourse 2 to 4 days before ovulation. The theory is that the Y sperm will die off, leaving only the hardier X sperm when the egg is released.
- Position: Shallow penetration is recommended to expose sperm to the acidic entrance of the vagina, which filters out the Y sperm.
Is the Shettles Method Accurate in 2026?
Dr. Shettles claimed a 75-90% success rate, but modern medical studies have shown mixed results. While the biology of sperm is well-understood, many factors—like the mother's pH levels and stress—can affect the outcome. In 2026, most doctors consider it a 50/50 chance.
