The predictive value of using a combined Z-score and day 3 embryo morphology score in the assessment of embryo survival on day 5

28 May 2003

Abstract excerpt

BACKGROUND: The purpose of this study was to evaluate the ability of using the Z-score alone, or, in combination with the day 3 embryo morphology score, to predict embryo viability at day 5 from a large cohort of embryos derived from patients undergoing treatment with IVF/ICSI. METHODS AND RESULTS: In this retrospective study, a total of 1894 zygotes from 346 treatment cycles (295 couples) was analysed between...
