What is Euploid abortion?
We defined euploid losses as pregnancies losses with: aCGH on the product of conception (POC) showing euploid (normal) karyotype. Normal PGD (Preimplantation genetic diagnosis) tested embryo with a fetal heartbeat (FHB) detected prior to the loss. Clinical pregnancy (>6 weeks) with a FHB detection prior to the loss.
Why do Euploid embryos miscarry?
Discussion. Our data suggest that PGS using aCGH may fail to identify some cases of mosaicism and polyploidies. Of miscarriages after transfer of presumed euploid embryos by aCGH, 36.8% were chromosomally abnormal as determined by NGS. Undetected chromosomal abnormalities may contribute to early pregnancy loss.
What is a inevitable abortion definition?
Inevitable abortion: the cervix has dilated, but the products of conception have not been expelled. Missed abortion: a pregnancy in which there is a fetal demise (usually for a number of weeks) but no uterine activity to expel the products of conception.
Should I do IVF after 3 miscarriages?
Three or more miscarriages occur in less than 1% of women. The good news is, In Vitro Fertilization (IVF) with genetic testing, can significantly lower the risk of miscarriage and increase chances for a successful pregnancy.

What is a Euploid embryo?
An embryo that contains a normal number of chromosomes is a ‘euploid’ embryo. An embryo that carries an abnormal number of chromosomes is ‘aneuploid’. Examples of aneuploid embryos include trisomy 18 and trisomy 21, otherwise known as Edward syndrome and Down Syndrome respectively.
Is euploid normal?
A Euploid embryo is an embryo that has the correct number of chromosomes and is considered a normal embryo. Euploid or normal embryos are the ones we hope to transfer for our patients.
Why do chromosomally normal embryos miscarry?
The embryo may be completely normal. The embryo may end up with a balanced amount of chromosome material and end up like the parent, essentially, a carrier of the problem. The embryo may end up with an unbalanced amount of chromosomal material. These embryos, like the aneuploidies will be miscarried.
What is the difference between inevitable abortion and threatened abortion?
A threatened abortion referred to the clinical presentation of bleeding in the presence of a closed cervical os. The term inevitable abortion was invoked in the setting of bleeding and an open cervical os before the passage of pregnancy tissue.
What are the different types of spontaneous abortion?
What Are the Different Types of Miscarriage?

Is miscarriage higher with IVF?
Newly pregnant patients often wonder whether having undergone IVF puts them at an increased risk of having a miscarriage. The answer is no. IVF does not contribute to miscarriages.
Why do IVF pregnancies miscarry?
One of the most common reasons why IVF is unsuccessful, or why miscarriages occur, is because of chromosomal variations in the embryo. Up to 70% of embryos, whether created naturally or through IVF, are lost before birth. This usually occurs within the first three months of pregnancy, most often before implantation.
