usually, we use an incubator for embryo development. And daily, embryologists remove embryos from the incubator to evaluate the stages of embryo development under the stereo microscope. Due to this embryo getting a lot of exposure, it may affect embryo quality. For som...

Nonetheless, the study of human embryos poses a series of unique ethical and moral implications. The unique totipotent nature of a human embryo and its potential to develop into a child necessitates a level of restriction and regulatory control that is not present when studying other cell types....
When the organism is about nine weeks old, the embryo is called a fetus. At this stage, the fetus is about the size of a kidney bean and begins to take on the recognizable form of a human being as the “tail” begins to disappear. ...
