Objectives of Study:

Subfertility is a growing severe reproductive health problem and is estimated to affect approximately 15% of couples of reproductive ages. Although in-vitro fertilization and embryo transfer (IVF-ET) as an effective treatment for infertile couples is rapidly becoming more widely available, women who have diminished ovarian reserves (DOR) or with poor ovarian response (POR) to exogenous gonadotropin stimulation still pose challenges to reproductive experts. The results of two recent clinical studies in China showed that traditional Chinese medicine (TCM) formula Dingkun pill (DKP) showed a curative effect on improving the clinical pregnancy rate of DOR and POR women. However, the heterogeneity of these two studies does not provide definitive conclusions about the therapeutic effects of the formula. The purpose of this study was to investigate the effect of TCM formula DKP on improving the clinical outcome of IVF-ET in women with low prognosis through a carefully designed randomized controlled trial.
