Efficacy of Endometrial Receptivity Analysis (ERA)
Dr. Kyoung-yong Moon, MD
IORA Fertility Clinic (Korea)
Endometrial receptivity issues represent a potential source of implantation failure. The aim of this clinical study was to evaluate our experience with the endometrial receptivity array (ERA) among patients with a history of repetitive implantation failure.
In recent years, an efficacy of the ERA in Korea has been discussed and debated among physicians. So, we investigated whether the contribution of the endometrial factor could be identified with the ERA test and if actionable results can lead to improved outcomes such pregnancy rate increase.
Today, through a care review, we would like to discuss the efficacy of ERA.

ni-PGT-A, time for clinical application?
Dr. Chun-Kai Chen, MD MMSc
Hope Fertility and PGT center (Taiwan)
For the last thirty years, a variety of methods were developed to assess the chromosomal status of the embryos, initially FISH, followed by aCGH, then NGS. As to the method to get genetic material , cleavage stage biopsy was used before and nowadays blastocyst biopsy. However, the benefits of PGT-A were frequently questioned. The invasive biopsy procedure was suspected to decrease the implantation potential and the embryo mosaicism influence the reliability of PGT-A report. Both were to blame for the ineffectiveness of PGT-A on pregnancy rate.
Spent culture medium has been proposed as an alternative source of embryonic genetic material to retrieve. Different test methods for the non-invasive PGT-A (niPGT-A) were evaluated in the past few years. With continuous improvement of the procedure, the concordance rate ranged from 80-100% for the recent reports. The maternal contamination rate decreased a lot and false negative rate is improving. Accordingly, the concordance rate increasing. We introduce the test in our center recently will present the preliminary experience.
It seems the niPGT-A provides a priority of embryo selection for euploidy rather than diagnosis at the moment. Although there are still many aspects to refine, the niPGT is on its bright and promising way.

Impact of ERA, EMMA/ALICE on Euploid Embryo Transfer
Dr. Shinnosuke Komiya, MD
HORAC IVF Grand Front (Japan)
In Japan, PGT-A can only be used to a limited extent. Euploid embryos can theoretically reduce the miscarriage rate, and, in fact, we have experienced pregnancies in RIF cases after PGT-A embryo transfers. But there are still cases of repeated implantation failure even after embryo selection. In this study, we retrospectively analyzed the impact of ERA and EMMA/ALICE tests on euploid embryo transfers performed in our clinic.

Mosaic embryo transfer strategy, an update
Dr. Jason Yen-Ping Ho, MD
Taipei Fertility Center (Taiwan)
Advances in NSG-based Preimplantation Genetic Testing for Aneuploidy (PGT-A) have led to practice changes in ART; however, overwhelmed details also raised the controversy of management of chromosomal mosaicism especially when no euploid embryos are available. Chromosomal mosaicism majorly develops during mitosis of embryos after fertilization. Although there is no direct evidence to support that mosaic blastocyst has the capacity to develop normally after implantation, increasing studies have showed that transfer of putative mosaic blastocysts may result in healthy live births with marked lower ongoing pregnancy rate in comparison with the transfer of euploid blastocysts. We reviewed the latest reports on mosaic embryo transfer and try to made a strategic recommendation.

Molecular analysis of Products of Conception (POC) provides comprehensive understanding of the chromosomal causes of clinical miscarriage
Dr. Nasser Al-Asmar Piñar, PhD
Igenomix (Spain – HQ)
The incidence of spontaneous clinical abortion in the general population is 15%. Most of them (~80%) occur before the 12th week of gestation, which could be considered as a biological barrier. Aneuploidies are alterations in the number of chromosomes that can cause spontaneous abortions and chromosomal abnormalities in newborns. More than 50% of miscarriages in the first trimester, whether spontaneous or following assisted reproduction treatments (ART), are the result of chromosomal abnormalities. To analyze de POC is important to give an explanation to the patient why the pregnancy loss has occurred if it is abnormal. If it is normal, we will have to focus on another possible cause that is not chromosomal: endometrial, endocrine, immunological, thrombophilic… To provide best reproductive advice for a future cycle, whether it is trying to get pregnant naturally at home or going thru ART. Molecular techniques (NGS), combined with the use of STRs, make it possible to increase the efficiency of the analysis of chromosomal abnormalities of POCs compared to conventional cytogenetic techniques, improving the percentage of samples with informative results, and reducing the rate of false negatives caused by contamination with maternal DNA.
Nasser Al-Asmar received his Bachelor’s degree in Pharmacy, a Master’s degree in Biotechnology of Human Assisted Reproduction and his PhD in Biomedicine and Biotechnology at Valencia University, Valencia, Spain. He was Laboratory Manager at Igenomix USA (Miami, FL) from its opening in 2012 until January 2016, when he became Scientific Advisor first in the USA and now for Spain and Latam. He is a member of the permanent board of the Genetics Interest Group of ASEBIR (Association for the Study of the Biology of Reproduction) and Professor at the Master of Biology and Technology of Mammal Reproduction at the University of Murcia (UMU), Spain. Nasser Al-Asmar has over 15 years of clinical and research laboratory experience. In the clinical setting, he has extensive experience in the study of chromosomal abnormalities in embryos (PGT-A) and spermatozoa using array CGH technology, fluorescence “in situ” hybridization (FISH) and Next Generation Sequencing, analyzing Products of Conception as well. In 2019 Nasser Al-Asmar had lectures in International Conferences in several countries such as Argentina, India, Nigeria, Kuwait, Japan, Hong Kong, Spain… about all different topics in Reproductive Genetics. In 2020 he had the same experience but virtually, giving lectures in different Conferences for Austria, Ukraine, Perú, Brazil, Taiwan, India, Dubai, KSA, Spain…
