Figure 2From: The new Rapid-i carrier is an effective system for human embryo vitrification at both the blastocyst and cleavage stageBlastocoel reduction using a mechanical technique. Artificial collapse of an expanded blastocyst is shown. (a,b) An ICSI needle is used to pierce the blastocyst in an area distal to the inner cell mass. (c) Within 5 minutes, blastocoelic fluid has leaked out and blastocoel volume is reduced. Magnification 300 ×.Back to article page
