Intravenous immunoglobulin for patients with repeated failure of in vitro fertilization-embryo transfer / 대한산부인과학회잡지

ABSTRACT

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.
