2. Figure 1
Examples of morphologic changes of frozen blastocysts after thaw and post-thaw culture. (A) Frozen blastocyst immediately after thawing; (B) blastocyst starting to shrink in 0.5 mol/L sucrose; (C) blastocyst shrunk tightly after further dehydration for 10 minutes in 0.2 mol/L sucrose; (D) blastocyst starting to re-expand after 1 hour in vitro culture; (E) blastocyst with >50% blastocoele re-expansion after 2 hours in vitro culture before ET. Original magnification, ×400.

3. Figure 2
Impact of blastomere loss on blastocyst survival (blue bar) and fast blastocoele re-expansion (red bar). Significantly higher rates of blastocyst survival and fast blastocoele re-expansion were obtained for fully intact blastocysts as compared with partially intact blastocysts with different ranges of blastomere loss (P<.01).
