IVF or in vitro fertilization is a fertilization method in which the egg is fertilized by sperm outside the body, in a test tube. The success rate of this method depends on many factors, in which the environment for the embryo to implant and develop in the uterine lining plays an important role. Therefore, the ERA testing method was born to improve the success rate of IVF.

The timing of the embryo transfer should be consistent with your menstrual cycle, not too early or too late, but at the right time. For most women, the best time to transfer the embryo is the same, but for some women it may be different.
