OBJECTIVE: To study the clinical outcomes of single frozen-thawed blastocyst transfer cycles according to the hatching status of frozen-thawed blastocysts. METHODS: Frozen-thawed blastocysts were divided into three groups according to their hatching status as follows: less-than-expanded blastocyst (≤EdB), hatching blastocyst (HgB), and hatched blastocyst (HdB). The female age and infertility factors of each group were evaluated. The quality of the single frozen-thawed blastocyst was also graded as grade A, tightly packed inner cell mass (ICM) and many cells organized in the trophectoderm epithelium (TE); grade B, several and loose ICM and TE; and grade C, very few ICM and a few cells in the TE. The clinical pregnancy and implantation rate were compared between each group. The data were analyzed by either t-test or chi-square analysis. RESULTS: There were no statistically significant differences in average female ages, infertility factors, or the distribution of blastocyst grades A, B, and C in each group. There was no significant difference in the clinical pregnancy and implantation rate of each group according to their blastocyst grade. However, there was a significant difference in the clinical pregnancy and implantation rate between each group. In the HdB group, the clinical pregnancy and implantation rate were similar regardless of the blastocyst quality. CONCLUSION: There was an effect on the clinical outcomes depending on whether the blastocyst hatched during single frozen-thawed blastocyst transfer. When performing single frozen-thawed blastocyst transfer, the hatching status of the frozen-thawed blastocyst may be a more important parameter for clinical outcomes than the quality of the frozen-thawed blastocyst.

OBJECTIVE: The implantation failure after embryo-transfer (ET) is a major continuing problem in in vitro fertilization (IVF). This study was undertaken to determine the effectiveness of intravenous immunoglobulin for treatment of individuals experiencing repeated unexplained in vitro fertilization-embryo transfer (IVF-ET) failure. METHODS: A total of nine consecutive infertile patients who failed to become pregnant after previous IVF-ET replacing at least three or more normal developed embryos each were included in our study. During the subsequent new IVF-ET cycle, each women received intravenous immunoglobulin 500mg/kg before the embryo transfer. RESULTS: Only one implantation occurred. There were no remarkable side effects. A specific effect of intravenous immunoglobulin for patients with repeated IVF-ET failure could not be demonstrated. CONCLUSION: High-dose intravenous immunoglobulin may not be useful for patients with repeated failure of embryo transfer.
