Abstract:
In vitro fertilization-embryo transfer (IVF-ET) therapy for subfertile couples has become widespread. However, it has been reported that high frequency uterine contractions at the time of embryo transfer influence adversely IVF-ET outcome. This article focuses on the methods of administration of shakuyakukanzoto combined with ET for subfertile women. 186 patients who underwent IVF-ET were recruited. 94 women undergoing IVF were randomly assigned to ET with shakuyakukanzoto for 4 days or 92 with no treatment. Background characteristics (age, number of embryo transferred, quality, and luteal function) were similar in the two groups. Pregnancy rate was 33.0% in the shakuyakukanzoto group as compared with 20.7% in the nontreated group. The increased pregnancy rate with shakuyakukanzoto compared with no treated was significant. However, the precise mechanism to explain for the results of this investigation remains to be unclear. Therefore, further research might be necessary to evaluate the effect of shakuyakukanzoto, at the time of ET.
