Genetic Test to Determine the Best Embryo

Technical

Synchrony
Benefits
Indications

The aim of our work at IGENOMIX is to help families to achieve a pregnancy that will lead to a healthy baby at home.
There are two main factors to consider in order to maximize the chances of implantation during an IVF treatment; a chromosomally normal embryo and a receptive endometrium.

What is PGS + ERA Synchrony?

Embryo factor: PGS (PGT-A)

PGT-A testing analyzes the embryos obtained during an IVF cycle.
Determines which embryos have a normal number of chromosomes.
Embryos with the correct number of chromosomes have higher chances of implantation.

More Info

Endometrial factor: ERA

ERA test analyzes the woman’s endometrium, where the embryo is to implant.
Only an endometrium in a receptive stage will allow implantation.
ERA test will determine if the endometrium is receptive or not at the time of sampling, helping the clinician to schedule transfer at the right time.

Why PGS + ERA Synchrony?

Reduced miscarriage rates.
Higher pregnancy rates per transfer.
Fewer cycles of IVF treatment needed (less time and money).
Greater chance of having a healthy child.
Fewer wasted transfers (implantation failure).
If both the embryo and the endometrium are synchronized, the IVF clinician can transfer the right embryo at the right time.
Combining IGENOMIX ERA and PGT-A allows to cover the two key factors to achieve your goal, a healthy baby at home.

Who should use PGS+ERA Synchrony?

Advanced maternal age: 35 years or above
Recurrent miscarriages: 2 or more miscarriages of unknown cause
Assisted reproduction cycles without pregnancy: 2 or more assisted reproduction cycles without pregnancy result
Male factor: Males with low sperm concentration, below 5 million per ml
Previous pregnancies with anomalies: 1 previous pregnancy with chromosome abnormality, especially in an assisted reproduction cycle
