Chinese herbal medicines as complementary therapy to in vitro fertilization-embryo transfer in women with infertility: protocols and applications.

ABSTRACT

In vitro fertilization-embryo transfer (IVF-ET) is a very common treatment for couples with infertility. However, IVF-ET still has a limited success rate with high costs. Chinese herbal medicines (CHM) have been used as complementary treatments for infertility to improve the reproductive outcomes during different stages of the IVF-ET cycle. This review provides an up to date evidence on CHM treatments. We summarize the treatment protocols based on the stages of IVF-ET cycle and discuss its clinical applications in IVF-ET treatment. The possible underlying mechanisms of CHM include improving ovarian function, promoting endometrial receptivity, regulating immune function, inhibiting oxidation, and reducing mental stress and discomfort during treatment. This review aims to provide information and guidance on the potential clinical applications of CHM as an adjuvant therapy during IVF-ET treatment.
