An embryo’s ability to develop could stop for a variety of causes. The embryo might have slowed growth or decreased metabolic activity, which would cause it to degenerate. During certain phases of development, embryos can also stop developing. For numerous causes, some of which are covered below, they may not develop to the blastocyst stage.
The development of the embryo’s early cleavage is dependent on unique substances found inside the egg. Sometimes, flaws in an embryo’s growth reveal the quality of the egg and can prevent the embryo from continuing to divide.
Apoptosis, commonly known as programmed cell death, can occur in embryos. An early biological process called apoptosis purports to eliminate any undesirable or damaged cells from the developing embryo. A sufficient amount of apoptosis can prevent the embryo from continuing to develop.
