Should Your Consider PGT-A with Your IVF Treatment?

January 13, 2022

By: Peter Ahlering, MD All humans, at any age, have some risk of producing aneuploid embryos; that is, genetically abnormal embryos with more than or fewer than 46 chromosomes.  We are able to detect whether an embryo is aneuploid or not through the use of pregenetic implantation testing for aneuploidy (PGT-A).  Generally, aneuploid embryos are…

Should you consider the ERA test prior to your embryo transfer?

October 26, 2021

The egg retrieval is done, the embryos have been created and are frozen.  A patient may now ask, “Should we postpone an embryo transfer to do an ERA?”  To best answer that question one must understand the processes related to this test and weigh the benefits.  The Endometrial Receptivity Assay (ERA) test involves three weeks…

Myth: Miscarriages arising from chromosomally abnormal (aneuploid) embryos occur only in older women

May 19, 2020

Although increased age is a risk factor for embryo aneuploidy (abnormality) and miscarriages, younger women (<35) are at substantial risk for producing aneuploid embryos particularly when they have a history of recurrent miscarriages.  It may be that in these women the uterine lining is too selective.  In other words, the uterine lining is inappropriately allowing…

Implantation Failure and The Endometrial Receptivity ERA: Important Points To Know

July 12, 2018

For several decades we in the reproductive medical field have been trying to identify reasons that apparently normal embryos fail to implant. That is once transferred in the context of in vitro fertilization (IVF), the embryo fails to result in a positive pregnancy test.  Certainly, we know that certain uterine abnormalities can contribute to the…

Could Pre-Implantation (PGS) Testing Be Completed Non-Invasively?

July 12, 2018

Last week, the European Society for Human Reproduction and Embryology hosted their annual meeting in Barcelona. One of the interesting studies released was that from Igenomix, “Improved concordance rates for aneuploidy detection in spent culture media compared to trophyectoderm biopsies: a step forward towards non-invasive pre-implantation genetic testing.” Today, in order to complete the PGS…

Chaos In The Embryo: Genetics + Fertility = Outcome

April 4, 2016

Recent literature and studies have shown that through the use of chromosomal assessment , human embryos are even more unstable than previously thought. An analysis of embryos derived from fertility treatments, reveals the high rate of abnormalities in these embryos. It has been well known for a long time that high rates of chromosomal abnormality occur in human eggs which leads to chromosomal abnormalities (aneuplo)
