Researchers have found a way to pause the development of early mouse embryos for up to a month in the lab, a finding with potential implications for assisted reproduction, regenerative medicine, aging ...

Obstetricians and gynecologists at Toho University, Japan examined 1,331 cases of frozen-thawed embryo transfer cycles and found that blastocysts showing shrinkage at the time of transfer had a low ...

An international collaboration of researchers from the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan and Gladstone Institutes in the U.S. have generated 3-D blastocyst-like structures ...

Human reproduction is an inefficient process, with less than one third of conceptions leading to live births. Failure of the embryo to implant in the uterus is one of the main causes of miscarriage.

This study is led by Prof. Lei Jin and Dr. Lixia Zhu (Reproductive Medicine Center, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology). Assisted reproductive ...

Chromosomal aneuploidy is recognized as a factor that contributes to unsuccessful embryo implantation and spontaneous abortion. It provides an explanation for the relatively low success rate of in ...

Scientists have evaluated the adverse effects of blastocyst shrinkage on the reproductive outcomes of frozen-thawed embryo transfer. The effect was evident in embryos with morphologically ...
