A medical program by a research team from the Chongqing Health Center for Women and Children (CQHCWC) won a municipal third-place award for science progress in 2019. The award ceremony was held in the municipality on Sept 22.

CQHCWC's award-winning project focused on the application of precision medicine in assisted reproduction. It was conducted and completed by a research group led by Huang Guoning, the chief physician of CQHCWC's Center for Reproductive Medicine.

Accurate evaluation of embryo quality and precise identification of the endometrial implantation window are essential to determining assisted reproduction's clinical outcomes. Meanwhile, in traditional assisted reproduction technology, embryo quality assessment is scored only by observation under a light microscope, which is not accurate, comprehensive and objective enough.

The award-winning project focuses on a series of basic and clinical technology studies around the above issues. It clarifies the kinetic parameters for evaluating embryo quality and identifies endometrial receptivity biomarkers during the uterine implantation window. The project has formed a full-chain technology system covering embryo quality assessment, pre-implantation genetic diagnosis and endometrial implantation window identification, which improves the clinical pregnancy rate.

At the same time, ineffective and excessive medical treatments in assisted reproduction are reduced, which is of positive significance for optimizing the effectiveness of disease diagnosis and treatment and improving the national health level.

The Center for Reproductive Medicine is CQHCWC's leading department, and the center's clinical diagnosis and treatment technology are at the top level in Chongqing. The hospital will continue to increase its investment in talent training and basic research at the center in the future, as it strives to become a world-class center in the field of reproductive medicine.
