Timing Your Conception: Can You Influence Your Baby's Gender?
Exploring the Shettles Method—the art and science of timing your baby's arrival.
If you are in the "Planning & Hope" phase of your journey, you've likely wondered: "Is there a way to influence whether I have a boy or a girl?" While nature ultimately makes the final call, many parents-to-be follow a famous strategy known as the Shettles Method to tip the scales.
The core of this method isn't magic—it's timing. To make this work, you can't just guess; you need to know exactly when you are ovulating. This is where using a specialized tool like our Free Ovulation Calculator becomes your best friend in the planning process.
The Science of "Boy" vs. "Girl" Sperm
Dr. Landrum Shettles discovered that "Boy" sperm (Y-carrying) and "Girl" sperm (X-carrying) behave differently. Y-sperm are smaller, faster "sprinters" but they die quickly. X-sperm are larger, slower "marathon runners" that are much heartier and live longer.
How to Time for a Baby Boy
Hoping for a son? The Shettles Method suggests having intercourse as close to ovulation as possible. Because boy sperm are faster, they can reach the egg first if it has just been released. To get this right, you should track your peak fertility window daily.
Step 1: Find Your Fertile Window
Before you can time your conception, you need to know your dates!

Dreaming of a daughter? The strategy is to have intercourse 2 to 4 days before you ovulate. Since girl sperm are survivors, they can wait in the reproductive tract while the faster boy sperm die off before the egg arrives.
Why Tracking is Essential
The biggest mistake couples make is "guessing" their cycle length. Every woman is different, and stress or travel can shift your ovulation day. By using our calculator to log your last period, you get a customized roadmap for your conception journey.
Already Pregnant?
