Pregnancy outcome following transfer of human blastocysts vitrified on electron microscopy grids after induced collapse of the blastocoele
1 Jan 2003
Abstract excerpt
BACKGROUND: The purpose of this study was to examine the effects on blastocyst survival and subsequent pregnancy rate of 'artificial shrinkage' (i.e. induced collapse of the blastocoele) before vitrification of human blastocysts. METHODS: After embryo transfer in IVF cycles, surplus embryos that developed to the expanded blastocyst stage were cryopreserved. Before vitrification on electron microscopy (EM) grids,...
