Preimplantation    genetic    testing    for     structural rearrangements (PGT-SR) is  a  technique   used   to detect  chromosomal    structural    abnormalities  in embryos during   in   vitro   fertilization   (IVF).   It   is applied     to    couples    who    carry   chromosomal rearrangements, such as translocations,  inversions, or  deletions,   which   may   increase   the    risk   of miscarriage or genetic disorders.  PGT-SR   involves analyzing embryos  for   these   structural   changes before implantation. By identifying embryos without such abnormalities, it helps increase the chances of a    healthy   pregnancy.   The   procedure   includes embryo biopsy followed by genetic testing.  PGT-SR is particularly beneficial for individuals  with   known chromosomal     rearrangements   or   a   history   of pregnancy loss. This testing   reduces   the   risk  of passing on structural chromosomal abnormalities to the offspring.
