Selecting the healthiest embryo is one of the most important steps in in ‑ vitro fertilization (IVF), yet it remains one of ...

Embryologists typically assess an IVF embryo's quality by examining it under a microscope. If it looks relatively normal but there are reasons to suspect possible problems, such as in cases of ...

Researchers at Vanderbilt University have developed a new embryo culture dish that significantly improves microscope imaging, a longstanding barrier in in‑vitro fertilization (IVF). Traditional 3D ...

Recurring questions, seeing and believing -- Hypothetical and observed embryos with microscopes at work -- Experimental embryos in the laboratory -- Inherited, evolved, and computed embryos -- The ...

When sperm meets egg, the start of life is not quiet. Under a special microscope, researchers have watched a tiny light show at fertilization. They see a microscopic flash at fertilization, a burst of ...

A time-lapse film offers a glimpse of a hidden milestone of human development: the moment when the newly formed embryo latches onto the uterine lining. Researchers have captured real-time footage of ...

Under his microscope, Jun Wu could see several tiny spheres, each less than 1 millimetre wide. They looked just like human embryos: a dark cluster of cells surrounded by a cavity, and then another ...
