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 ...

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 ...

Physiological and molecular processes initiated during implantation for pregnancy success are complex but highly organized. This review primarily highlights adverse ripple effects arising from defects ...

We know much about how embryos develop, but one key stage -- implantation -- has remained a mystery. Now, scientists have discovered a way to study and film this 'black box' of development. This new ...

In a study of early embryonic development in primates, an international research team under the leadership of Berthold Huppertz and Thomas Kroneis from Med Uni Graz has shown for the first time that ...

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.

Your body undergoes a dramatic process from the time of conception to the first positive pregnancy test. One of the most significant steps is implantation. Implantation is an early sign of pregnancy ...

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 ...

Pregnancy begins when the fertilized egg implants in the uterine lining. Here's what to know about implantation and how long after fertilization it occurs. Reviewed by Rachel Gurevich, RN When you're ...

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 ...
