PREEMBRYO Meaning and
Definition
-
The term "preembryo" refers to an early stage of development after fertilization but prior to the implantation of the embryo in the uterus. The preembryo is formed when the sperm and egg unite to form a zygote through the process of fertilization. During this stage, the zygote undergoes rapid cell division, forming a cluster of cells known as the blastocyst.
The preembryo stage typically lasts for approximately the first week following fertilization, during which time it remains in the fallopian tube. It is during this week that the preembryo migrates from the fallopian tube to the uterus, where it eventually implants itself in the uterine lining and proceeds to develop into an embryo.
The term "preembryo" is primarily used in embryology and reproductive sciences to describe the early stages of human development. It is worth noting that the use of the term "preembryo" is not without controversy, as some argue that it implies a distinct and separate stage of development, while others consider it to be more of a semantic distinction.
In summary, the term "preembryo" refers to the early stage of development after fertilization but prior to implantation in the uterus. It is characterized by rapid cell division and the formation of a blastocyst.

Etymology of PREEMBRYO
The term "preembryo" is not widely used in scientific literature and has different interpretations based on context.
In the context of human development, the term "preembryo" was coined by developmental biologist Clifford Grobstein in 1986. It refers to the early stage of human development after fertilization but before the implantation of the fertilized egg into the uterus. Grobstein introduced the term to emphasize the ethical implications of research involving human embryos.
The term "preembryo" combines the prefix "pre-" meaning before, and "embryo", derived from the Latin word "embryonem" meaning "that which grows". So, etymologically, "preembryo" means "before the growing stage of an embryo".
