Summary

More than 8 million babies have been born through in vitro fertilization (IVF). Non-invasive observation of embryos in vitro to better understand their development is becoming increasingly important. Morphology has been used as standard from the beginning, but has the disadvantage of subjectivity. Now the emphasis in basic and clinical research is on developing rapid, quantitative, non-invasive tests. Hence comes the idea of metabolic profiling of spent embryo culture medium (SECM) as a biomarker. This could be useful for understanding and improving the nutritional environment of oocytes and embryos. The goal of our study is to determine metabolic profiles of the SECM in combination with morphological assessments to better understand the nutritional requirements of the embryo. The goal would be to optimize media specifically, depending on patient and embryo characteristics ("personalized medicine") ("the embryo in vitro as patient").

Detailed description

Following successful fertilization (day 1), each embryo will be cultured for 5-6 days (day 5-6) to form the blastocyst. Then, morphological evaluation will be performed by an expert embryologist to confirm poor and good embryo quality. At the end of the culture, 50 µl of SECM will be collected from each embryo and stored for metabolomics analysis. Samples including medium only and no embryos will be used as controls. The metabolome will be characterized in SECM samples using the respective assay targeted kit.
