P–258 Ubiquitin, in the human embryo secretome, is a biomarker for embryo viability: a potential predictor of live-births, post embryo transfer

Study question Whether embryo-secreted ubiquitin could serve as a predictive biomarker for embryo development and viability for assessing pregnancy outcome? Summary answer Embryo-secreted ubiquitin concentrations showed positive correlations with (a) developing embryonic stages, (b) implantation rates, (iii) live-birth rates. Their altered levels were associated with miscarriages. What is known already Human infertility affects 15–20% couple and...
