Assessment of the implantation of day-2 human embryos by morphometric nonsubjective parameters

Objective: To demonstrate the usefulness of image analysis in designing objective embryonic morphometric variables. Design: Retrospective study of 214 top-quality day-2 embryo photographs from 50 double-embryo transfers resulting in no pregnancy (group 0) and 57 resulting in twin pregnancy (group 1). Setting: Human reproduction unit. Patient(s): Study of 107 in vitro fertilization-intracytoplasmic sperm injection (IVF-ICSI) cycles in women age
