The time of embryo transfer must be in accordance with your body's menstrual cycle, neither too early nor too late, but at the right time. For most women, the best time to have an embryo transfer is the same, but for some women, it may be different.

1. What is the endometrium?


The inside of the uterus is lined with a layer of tissue called the endometrium, which is prepared every month for the emergence of an embryo and it is the nest, where the embryo implants and resides during pregnancy. Even the best embryos will not be able to implant if the conditions are not right.

2. What is a nesting window?

The endometrium is receptive when it is ready for embryo implantation. This receptive period is called the nesting period.
Each woman has her own window. Knowing your individual implantation time can help you optimize your chances of getting pregnant when you perform an individual embryo transfer.

3. What is the window-implantation assessment (ERA) test?


As a diagnostic test when embryo transfer is appropriate for each woman. This timing is individualized to the individual and thus synchronizes the embryo transfer and the individual's nesting window.

Need to take back biopsy sample to repeat the test The possibility of pregnancy is not 100%: even with the right time of the implantation window, the chance of pregnancy is still not 100% because it depends on many factors such as: embryo quality, embryo genetic abnormalities ERA test does not evaluate endometrial problems, nor does it predict the quality of pregnancy
