Find the Mother's Lunar Age: The chart uses the mother's age according to the Chinese lunar calendar, which may be different from her Western (Gregorian) age.

Find the Conception Month: The chart also relies on the lunar month of conception.

Match Age & Month: Using the chart, find the intersection of the mother's lunar age and conception month to see if it predicts a boy or girl.

. This method is not scientifically proven and is more for fun than accuracy.

. Some claim around 50-70% accuracy, but there's no scientific basis for it.

The scientific ways to determine a baby’s sex are much more accurate than methods like the Chinese Gender Predictor. Here are the most reliable methods:

1. Ultrasound (Most Common – 18-22 Weeks) 🏥
   • The anatomy scan ultrasound (done at 18-22 weeks of pregnancy) is the most common way to determine sex.
   • A trained sonographer checks the baby's genitalia—a penis for a boy, labia for a girl.
   • Accuracy: 85-99%, depending on the baby's position and the skill of the technician.
2. NIPT (Non-Invasive Prenatal Test – 10+ Weeks) 🧬
   • A blood test from the mother detects the baby’s DNA in her bloodstream.
   • If Y chromosomes are found → It's a boy. If no Y chromosomes → It's a girl.
   • Done as early as 10 weeks.
   • Accuracy: 99%.
3. CVS (Chorionic Villus Sampling – 10-13 Weeks) & Amniocentesis (15-20 Weeks) 🧪
   • These are genetic tests that check the baby’s chromosomes (XX for a girl, XY for a boy).
   • Done for medical reasons (like checking for genetic disorders).
   • Accuracy: 100%, but slightly higher risk since they are invasive procedures.
4. IVF with Preimplantation Genetic Testing (Before Pregnancy) 🏗️
   • If parents undergo IVF, they can choose to test embryos before implantation.
   • PGT-A or PGT-M tests chromosomes, letting parents choose a male or female embryo.
   • Accuracy: 100% (if tested correctly).
