Baby Boy Conception Planner (Shettles Method)
Identify the precise 24-hour window for conceiving a boy using cycle tracking and Shettles Method logic. Features dietary tips and probability zones.
About
Conceiving a male child often requires a different strategy than conceiving a female. According to Dr. Shettles, Y-chromosome sperm (male) are lighter, smaller, and faster than their female counterparts, but they are also more fragile and have shorter lifespans. To favor a boy, timing is critical. Intercourse should occur as close to the moment of ovulation as possible. This ensures the fast-swimming Y-sperm reach the egg first before they perish. This planner calculates the peak fertility hours where cervical fluid conditions are most alkaline, which protects the fragile Y-sperm. Users should combine this calculator with ovulation strips for maximum precision.
Formulas
The calculator targets the "Peak Window" (Wboy), which is a narrow timeframe surrounding the estimated ovulation (O).
Optimal timing is strictly within this range to maximize Y-sperm competition.
