Infertility Clinical Trials

In current treatments for In Vitro Fertilization (IVF) and Intracytoplasmic Sperm Injection (ICSI), the creation of multiple embryos is a common practice. The decision to transfer an embryo is traditionally based on the morphological assessment by an embryologist, which, due to its nature, must be considered subjective. In certain regions, invasive embryo biopsy techniques, such as Preimplantation Genetic Testing for Aneuploidy (PGT-A), are used to detect chromosomal abnormalities and support decision-making regarding embryo transfer. However, there is a medical need to improve the outcomes of IVF/ICSI cycles through non-invasive and objective methods. As an academic center, our goal is to investigate promising innovative methods that, if successful, can be integrated into standard care. The aim of the Aurora blastocyst study is to evaluate the effectiveness of the Aurora test in selecting five-day-old embryos for fresh or frozen embryo transfer. Additionally, the study assesses whether the use of the Aurora test results in an increase in clinical pregnancy rates and live birth rates. The Aurora test is a non-invasive test for evaluating oocyte competence and subsequently the embryo obtained in an ICSI cycle (In Vitro Fertilization). This test is performed on cumulus cells (CC) surrounding the oocyte and uses mRNA expression profiles to evaluate the developmental potential of the oocytes. The test has been developed and validated for patients stimulated with human menopausal gonadotropins (HP-hMG), an ovulatory dose of hCG, and a single embryo transfer on day 3. The test will be performed by Fertiga nv, upon receiving patients cumulus cells. At our center, based on earlier research, the standard care involves a single embryo transfer on day 5. In this study, embryo selection based on morphology is compared with embryo selection based on morphology and the Aurora test. Finally, this study aims to evaluate the impact of the Aurora test score on the embryologist's selection decision for transferring a five-day-old embryo for single embryo transfer, by assessing parameters such as pregnancy rates and live birth rates.
