Recently, an original achievement of the team of the National Center for Assisted Reproductive and Eugenics Technology Research and Professor Chen Zijiang from the Research Center of Reproductive Medicine of Shandong University was published in the internationally renowned medical journal New England Journal of Medicine. The results showed that in the treatment of in vitro fertilization and embryo transfer (in vitro) in infertile patients with ovulation, the live birth rate and maternal complications of whole embryo frozen-freeze embryo transplantation were not compared with fresh embryo transfer. Significant differences.
It is understood that the IVF medical process is roughly divided into four steps: ovulation induction, in vitro fertilization and embryo culture, and embryo transfer. Transplantation can choose to transplant fresh embryos or frozen embryos. Frozen embryos undergo a "freeze-thaw" procedure relative to fresh embryos that require drug assistance.
In response to confusion and controversy, Professor Chen Zijiang's team conducted scientific design and rigorous multi-center large-sample randomized controlled trials. Through comparative studies, the team confirmed the reliability of “whole embryo freezing-frozen embryo transferâ€. Chen Zijiang believes 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.

Disposable latex gloves are divided into the following three levels. One is the powdered disposable latex gloves that are mostly used in the food industry. It is necessary to add them in the production process to prevent the gloves from sticking together and to facilitate wearing. It is important to note that there are good and bad cornmeal. We use food grade corn flour, otherwise it is not good for the user and the person being served. The second is the powder-free disposable latex gloves that are mostly used in the electronics and medical industries, because they are powdered when they are just produced, and the powder-free latex gloves obtained after our processing - washing with water. Third, they are mostly used in the precision electronics and medical industries. The purifying disposable latex gloves are made of powder-free latex gloves that have been washed with clean water and washed with chlorine again, and the cleanliness reaches a thousand grades.
