Input: Question: Does nuclear magnetic resonance metabolomic profiling of Day 3 and 5 embryo culture medium predict pregnancy outcome in good prognosis patients : a prospective cohort study on single transferred embryos?
Answer: In a large cohort of single transferred blastocysts from a homogeneous group of good prognosis patients, we find a high degree of individual variation in the metabolome that, however, has no relation to pregnancy outcome.

no
