What Exactly is an Embryo?

Merriam Webster’s Dictionary defines the term embryo as “an animal in the early stages of growth and differentiation that are characterized by cleavage, the laying down of fundamental tissues, and the formation of primitive organs and organ systems; especially the developing human individual from the time of implantation to the end of the eighth week after conception.”

Note: an embryo has tissues and organs; 4- to 5-day-old blastocysts in a lab do not. Implantation and conception are considered separate processes and are not synonymous with fertilization. Conception and fertilization are two distinct and individual events. While fertilization can occur either in a lab or inside a woman’s body, conception can only take place in the womb. Conception occurs when a blastocyst becomes implanted or attached to the lining of the uterus where it begins to receive nourishment for continued development.
