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 ...

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 ...

Extracellular vesicles (EVs) and their cargo microRNAs (miRNAs) are important regulators of embryo development to the blastocyst stage and beyond. Before implantation can take place, hatching of ...

The first steps of human development—those that occur within the first few weeks of pregnancy—remain mysterious in many ways. Within a week of fertilization, human embryos form a blastocyst, which ...

Researchers have identified Nr1h2, a critical transcription factor essential for early embryo development. Their findings enhance our understanding of gene regulation during blastoid formation and ...

Why doesn’t a ‘good’ embryo always lead to pregnancy in IVF? Explore key factors beyond embryo quality that affect IVF ...

Common implantation symptoms include cramping and spotting, or very light bleeding, but those same signs can also be indicative of a normal menstrual cycle. So how do you know when your symptoms ...
