The impact of implementing a non-invasive preimplantation genetic testing for aneuploidies (niPGT-A) embryo culture protocol on embryo viability and clinical outcomes.

Study Question: Are modifications in the embryo culture protocol needed to perform non-invasive preimplantation genetic testing for aneuploidies (niPGT-A) affecting clinical reproductive outcomes, including blastocyst development and pregnancy outcomes?

Summary Answer: The implementation of an embryo culture protocol to accommodate niPGT-A has no impact on blastocyst viability or pregnancy outcomes.

What Is Known Already: The recent identification of embryo cell-free (cf) DNA in spent blastocyst media has created the possibility of simplifying PGT-A. Concerns, however, have arisen at two levels.

Time-lapse evaluation of human embryo development in single versus sequential culture media--a sibling oocyte study.

Objective: To compare the dynamics of early development between embryos cultured in single and sequential media.

Design: Randomized, comparative study.

Setting: Private IVF centre.
