Abstract

According to WHO 2020, there are about 48 million infertility couples in the world currently. In recent years, assisted reproductive technology has been developed strongly and achieved significant milestones. According to Koot 2012, however, there are still about 8-10% of couples with recurrent implantation failure (RIF). One of the reasons, even with the good quality embryo or an euploid embryo transfer, is the abnormal endometrium or related to the implantation window. Thus, it is necessary to use molecular diagnostic tests including ERA, EMMA and ALICE to provide information on the implantation window of the endometrium, microbiome profile and chronic endometritis. At the ART Center of Tam Anh General Hospital in Hanoi, Vietnam, we have applied this trio-tests to patients who have RIF. From March 2020 to February 2022, 17 patients with recurrent implant failures were concurrently tested for ERA, EMMA and ALICE. In 13 patients had embryo transfer after the test, 6 patients got pregnant, in which 1 patient had five previous failures. This is a promising result, opening up hope for patients with RIF. However, the advantage of these tests needs more evidence to confirm.

Abstract

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, I 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 practical application of ERA.

Abstract

Assisted reproductive technology (ART) has evolved since 1978, and some new technologies pushed the technology up to new era. The biggest change in 2000s is brought by the clinical use of preimplantation genetic test (PGT). PGT increases clinical pregnancy rate and reduces spontaneous abortion per embryo transfer. Therefore, the relative importance of implantation failure has become greater. ERA test has been reported to be effective in case of implantation failure by many researchers. However, some researchers also reported the effectiveness as still sceptical. In this session, we want to confirm how effective is ERA test and how to use it in clinical management.

Abstract

Previous evidence indicates associations between the composition of the female reproductive tract microbiome and reproductive outcome in infertile patients undergoing assisted reproduction. We performed a multicentre prospective observational study using 16S rRNA gene sequencing to analyze endometrial fluid and biopsy samples before embryo transfer in a cohort of 342 infertile patients undergoing assisted reproductive treatments.

A dysbiotic endometrial microbiota profile composed of Atopobium, Bifidobacterium, Chryseobacterium, Gardnerella, Haemophilus, Klebsiella, Neisseria, Staphylococcus and Streptococcus was associated with unsuccessful outcomes (no pregnancy, biochemical pregnancy, and clinical miscarriage). In contrast, Lactobacillus was consistently enriched in patients with live birth outcomes. These findings indicate that endometrial microbiota composition before embryo transfer could be a useful biomarker to predict reproductive outcome, offering an opportunity to further improve diagnosis and treatment strategies.
