China's "test tube baby" frozen embryo transplantation research results have been recognized by the international medical community

Medical Network January 12th Chinese medical experts in the treatment of infertility in a unique way, through the comparative study to confirm the "full embryo cryo-freezing embryo transfer" reliability research results, the international medical community is highly recognized.

The "full embryo freezing strategy" is a hot issue that has been widely concerned in the field of reproductive medicine in recent years. "Test-tube baby" technique in clinical applications there is a long controversy and confusion on infertility treatment. Professor Chen Zijiang from the Research Center of Reproductive Medicine, Shandong University, through a multicenter randomized controlled clinical study of "comparison of frozen embryos with fresh embryos in normal ovulation infertility patients", concluded that "in vitro infertility patients with normal ovulation are in vitro In fertilization and embryo transfer (in vitro), there was no significant difference in live birth rate and maternal complications between whole embryo frozen-freeze embryo transfer compared with fresh embryo transfer.

Chen Zijiang said that the significance of this conclusion is that it will provide further high-quality evidence-based medical evidence for clinical practice and individualized diagnosis and treatment of infertility, and for the clinically assisted reproductive technology (test tube baby technology) "full embryo freezing - frozen embryo The transplantation strategy provides a scientific basis for maximizing patient benefits, treatment effectiveness, long-term safety evaluation, and individualized application value. It will play a positive role in the revision and implementation of clinical practice and clinical treatment guidelines for assisted reproductive technology in the future.

In the interview, the reporter learned that the Chen Zijiang team had in 2016 "in the infertility of women with polycystic ovary syndrome (PCOS) characterized by ovulation disorders, compared with fresh embryo transfer, whole embryo freezing-freezing The conclusion that embryo transfer can significantly improve live birth rate and reduce major complications has been confirmed by the international medical community for the first time.

It is reported that the study carried out by affiliated reproductive Hospital, Renji Hospital, Shanghai Jiaotong University, Shandong University, China 20 Hospital Center for Reproductive Medicine jointly. "Comparison of transplanted frozen embryos and fresh embryos in patients with normal ovulation infertility" was published in the original paper in the New England Journal of Medicine (IF: 72.4) (NEngl JMed 2018, 378(2): 126-136).
