As a result, a common question many women ask when undergoing IVF treatment is how doctors select the best embryo. Until recently, this was based on morphology — which simply put, is how the embryo looks under the microscope. However, now, doctors have developed a test to assess the genetics how accurate is preimplantation genetic screening an embryo. This test is known as preimplantation how accurate is preimplantation genetic screening screening or PGS. The test is also called preimplantation genetic testing for aneuploidy or PGT-A.

Through identifying the best quality embryos, this test can improve success rates with chromosomally normal embryos. Essentially, PGS can help doctors select a chromosomally normal, high-quality embryo to implant into the uterus. Chromosomes are the containers that carry our genetic information or DNA. If an embryo has any deviation from 46 chromosomes — whether there is an extra or missing chromosome — it will be likely to result in a failed implantation, biochemical pregnancy, miscarriage, or a pregnancy affected by a chromosomal syndrome.

While women of any age are at risk of producing embryos with chromosomal imbalances, the risk increases as the egg source ages. This is why women who have babies later in lifeare more likely to have a pregnancy with a chromosomal imbalance. However, PGS is available to patients of any age. In the past, fertility specialists would transfer an what are the three theories of criminal behavior into the uterus three days after fertilization.

Now, research has shown that success rates with chromosomally normal embryos improve if they transfer a few days later. Now, doctors generally transfer the embryo at around five or six days into development, at blastocyst stage. Not only does this improve viability, but it also gives doctors the opportunity to perform a biopsy with a low risk of embryo arrest. The embryo biopsy can be utilized to perform preimplantation genetic screening or PGS. This test can identify chromosomally normal embryos, which increase the chances of a healthy pregnancy.

To perform the biopsy, an embryologist removes cells from the precursor placenta cells of the blastocyst embryo, called the trophectoderm. These outer cells are what eventually will become the placenta. PGS improves success rates because chromosomally normal embryos are much more likely to implant and result in pregnancy. Furthermore, PGS also reduces the chances of miscarriage, as the most common cause is chromosome abnormality.

Yes — a study conducted by the Colorado Center for Reproductive Medicine found that women ages had a similar live birth rate to women 37 or younger if a chromosomally what does colorado mean in native american embryo was transferred. Moreover, as the research we mention infers, PGS does not majorly impact implantation success in every case.

Therefore, before making any decisions about your treatment, carefully consult with a health professional and gather as much research as you can. With the right information, you can make sure you go into your fertility treatment feeling informed and empowered. How do Lesbian Couples Get Pregnant? A Simple Guide to Your Options.
