Outcome of Embryos Transferred After Initial Chaotic Results on PGT-A

Retrospective Observation of Outcomes of Embryos Transferred After Initial Chaotic Results on Preimplantation Genetic Testing for Aneuploidy (PGT-A)

This is a retrospective review of treatment outcomes from fertility clinics in The Prelude Network who have used Igenomix for PGT-A and have transferred embryos with initial chaotic results, regardless if re-biopsy was performed.

Primary objective: to observe the outcomes of embryos transferred with initial "chaotic" results on PGT-A via Igenomix.

Hypothesis: The transfer of chaotic embryos can result in clinical pregnancy, as defined by fetal heartbeat at 6-8 weeks gestation. Furthermore, these transfers may also result in live birth and expand reproductive potential for patients seeking IVF with PGT-A.

Inclusion Criteria:

• Patients that conducted PGT-A via Igenomix who have transferred an embryo with an initial chaotic result.

Exclusion Criteria:

• Patients who had multiple embryo transfer.
