简要总结
The purpose of this study is to investigate whether oral Gushen Antai pills supplementation for luteal phase support will improve ongoing pregnancy rate in women with normal ovarian reserve in fresh embryo transfer cycles.
详细描述
Infertility is a growing reproductive health problem, and it is estimated that approximately 15% of couples of reproductive ages are affected. The invention and popularity of IVF-ET technology, although improving sperm egg encounter and fertilization barriers and implanting early embryos from the uterine cavity in vitro, still do not solve the problem of the uterine implantation environment or endometrial receptivity, and the pregnancy rate needs to be further improved. However, traditional Chinese medicine (TCM) has an original theoretical understanding and exact efficacy for gynecological diseases, therefore, it is necessary to supplement TCM interventions with endometrial receptivity as described above.
TCM is a kind of traditional treatment method with thousands of years history in China, and some previous studies have shown its unique experience in assisting pregnancy and reduce vaginal bleeding in early pregnancy . Similar to the notion of "hypothalamus- pituitary-ovary axis" that is established by Western medicine, TCM also has deeply studied the reproductive regulation of kidney and proposed the concept of "kidney-Tian Gui-Chong Ren-uterine axis." According to TCM, "Kidney Governs Reproduction," and female infertility is closely related to kidney deficiency, and the main therapeutic principle of it involves tonification of the kidney.
GSATP is widely used as an adjunctive therapy in women with threatened abortion in China and the clinical effects reflected by the patients remained satisfactory. The function of GSATP is nourishing yin and tonifying the kidney, strengthening Chong and prevent miscarriage. GSATP is used in the early threatened abortion, which belongs to the kidney yin deficiency syndrome of traditional Chinese medicine. GSATP is made up of Dodder, uncaria, Scutellaria, Atractylodes macrocephala, white peony, rehmannia, Polygonum multiflorum, Dipsacus, Cistanche deserticola, mulberry parasitism. The main components of GSATP include baicalin, Atractylodes macrocephala polysaccharide, flavonoids from Cuscuta chinensis, rhynchophylline, polysaccharides, Cistanche polysaccharides, stilbene glycosides and anthraquinone glycosides and triterpenoid saponins, etc. Modern pharmacological studies have found that these ingredients can improve vascular function, regulate immune activity, inhibit uterine contraction and improve ovarian endocrine function, so GSATP may play a role in promoting embryo implantation and preventing pregnancy. However, to improve the success rate of embryo implantation is a complex process and has not been fully studied. Therefore, in treating complex diseases, multi-targeted therapy such as TCM might have unique advantages over western medicine treatment alone. Although GSATP is associated with very good response in patients, lack of high-quality evidence-based medicine has restricted its promotion. The combination of evidence-based medicine, modern medicine and traditional Chinese medicine is a huge field that involves continuous attention and efforts.
GSATP dramatically increased the ongoing pregnancy rate and decreased the prevalence of vaginal bleeding in patients undergoing frozen thawed embryo transfer in our previous study. Recently, it was demonstrated that luteal support combined with GSATP could dramatically increase embryo implantation and clinical pregnancy rates, as well as early pregnancy loss rates, in IVF-ET fresh embryo transfer cycles. However, the study's methodological deficiencies prevented it from reaching a definitive conclusion about GSATP's treatment effect. This was mostly attributed to the unspecified randomization process, the absence of distribution concealment and blinding, no placebo control, and vague inclusion and exclusion criteria. As a result, a well-designed randomized clinical trial is essential to estimate the efficiency and safety of GSATP in optimizing reproductive outcomes in women with normal ovarian reserve during fresh embryo transfer cycles.
