PGT-SR is recommended when a parent carries a structural chromosomal rearrangement — for example a translocation or inversion — that does not affect the parent’s health but can lead to embryos with extra or missing genetic material, recurrent miscarriage, or failed implantation. PGT-SR identifies embryos with a balanced chromosome makeup, increasing the chance of a viable pregnancy.
