Birth Defects Prevention Month Part 2: Chromosomes and PGD
To further boost your awareness during Birth Defects Prevention Month, let’s talk chromosomes. Sure, you paid attention during sophomore year biology class, but now that you’re trying to conceive, chromosomes are much more relevant.
There are 46 chromosomes in a human cell, half from the mother and half from the father. Chromosomal abnormalities are the result of duplication or deletion of a part or full chromosomes. Many chromosomally abnormal embryos will miscarry (about half of miscarriages are the result of chromosomal issues), but others result in a child born with birth defects, like Down Syndrome, Tay-Sachs, or Cystic Fibrosis.
How can you screen for chromosomal abnormalities, especially if you are over the age of 35 and trying to conceive? The answer is in vitro fertilization (IVF) with Preimplantation Genetic Diagnosis (PGD).
PGD is a sampling of embryonic cells in conjunction with IVF that can screen for the most common birth defects and allow embryologists to select the embryo with the best chances of developing into a healthy pregnancy.
