The XY programme: trying for a boy

Last updated

The Genesyx XY programme is a 90-day preconception programme for couples hoping for a boy. It follows the Shettles approach, with an XY formula, an XY nutrition guide, vaginal pH and ovulation tests, and a companion app for timing. No outcome is guaranteed.

What’s in the XY programme

  • XY Formula: three monthly packs.
  • XY nutrition guide: a route-specific eating plan for the 90 days.
  • Measure: vaginal pH test strips, ovulation tests and pregnancy tests.
  • Companion app: your pH readings, cycle day and timing window in one calm view.

Timing on the XY route

Following the Shettles method, the XY route focuses on intercourse as close to ovulation as possible. The companion app uses your ovulation test results to show your window.

Before you start

Genesyx is not a fertility treatment and cannot guarantee a boy. If you have been trying to conceive for more than a year, or have a health condition, speak to your GP first.

Evidence for the Shettles theory is mixed. Genesyx helps you follow the theory consistently; no outcome is guaranteed. This page is general information, not medical advice.
