Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study aims to evaluate the use of the embryo culture medium as a source of genetic material for PGT-A and validate a niPGT-A protocol using cfDNA in SCM.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This study aims to validate a noninvasive PGT-A (niPGT-A) method utilizing cfDNA released from the human blastocyst into the SCM.
Patients undergoing a fertility treatment with PGT-A due to secondary infertility will be recruited. On day 6 post fertilization, SCM will be collected prior to blastocyst biopsy. The SCM is normally discarded at this stage. Trophectoderm biopsy and sample collection will follow the IVF laboratory's standard practices for clinical PGT-A.
Three aneuploidy screening kits, relying on different whole genome amplification methods followed by NGS on the Ion GeneStudio™ S5 Prime System (ThermoFisher Scientific), will be compared. The concordance between cfDNA and trophectoderm biopsies will be evaluated for approximately 150 blastocysts with the best performing niPGT-A protocol.
Selection of the embryo(s) for transfer will be based solely on the PGT-A result from the biopsied cells. The patient's IVF+PGT-A treatment plan and timeline will not be altered.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Two types of samples (TE and SCM) will be collected for all blastocysts included in the study
PGT-A / niPGT-A
PGT-A and niPGT-A will be performed using next generation sequencing (NGS) analysis for chromosome copy number variation (CNV). Embryo transfers will rely solely on the results of PGT-A for trophectoderm biopsies.
