Chinese Gender Calendar for IVF

Using the traditional gender prediction chart with IVF and embryo transfer.

Important Reminder

The Chinese Gender Calendar is a traditional folklore method for entertainment only. For IVF pregnancies where embryo sex selection was performed, the sex is already determined by the selected embryo's chromosomes.

Which Date Should I Use for IVF?

For IVF pregnancies, you should use your embryo transfer date as the conception date. This is the date when the embryo was placed in the uterus.

Our calculator makes this easy:

  1. Select "IVF / Embryo Transfer" option
  2. Enter your transfer date
  3. The calculator uses this date directly for the prediction

Fresh vs. Frozen Embryo Transfer

Whether you had a fresh or frozen embryo transfer (FET), use the same approach:

  • Fresh transfer: Use the day the embryo was transferred
  • Frozen transfer (FET): Use the day the thawed embryo was transferred

The date of egg retrieval or fertilization is not used — only the transfer date matters for this traditional calculation.

What About Known-Sex Embryos?

If you used PGT-A (preimplantation genetic testing) and transferred an embryo of known sex, you already know your baby's biological sex with certainty.

In this case, the Chinese Gender Calendar is purely for entertainment — to see if the traditional folklore prediction matches what you already know.

A Note on Accuracy

The Chinese Gender Calendar has no scientific basis for any pregnancy, including IVF. A baby's sex is determined by chromosomes at fertilization:

  • The embryo's sex was determined when the egg and sperm combined
  • The mother's age and timing do not influence this
  • This applies equally to natural conception and IVF
