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 ...

Endometrial preparation is a critical step in both the natural and artificial frozen embryo transfer (FET) cycle because the development of the endometrium must be synchronized with the embryo ...

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 ...

Single-embryo transfer has been recommended to reduce the incidence of multiple gestations when in vitro fertilization is performed in women under 36 years of age. We designed a prospective, ...

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.

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 ...

The creation of cellular structures similar to blastocysts has enabled KAUST scientists to build an in vitro model that mimics the earliest moments of human embryogenesis. A blastocyst is the first ...

Scientists based at The Rockefeller University have created an experimental system that models the implantation of a human embryo. The new system, an adaptation of one used to recapitulate the ...

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 ...

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 ...

Researchers have generated 3D blastocyst-like structures from stem cells. The study shows that the blastocyst-like structures very closely resemble actual blastocysts, and even induce proper changes ...
