What is the Origin of Euploid Embryo?

The term "euploid" is a combination of the Greek prefix eu- meaning "good" or "true," and -ploid meaning "set of chromosomes." This genetic terminology is foundational to the field of cytogenetics and reproductive medicine. The clinical focus on euploidy intensified with the advent of technologies allowing for the reliable genetic screening of embryos prior to uterine transfer.

What is the Mechanism of Euploid Embryo?

The euploid state is achieved through the precise separation of chromosomes during meiosis in the formation of the egg and sperm, followed by accurate mitosis during the rapid cell divisions of the preimplantation embryo. This mechanism ensures that every cell in the developing embryo receives the proper genetic complement. The integrity of these genetic instructions is essential for normal cellular function, differentiation, and the coordinated development necessary for a viable pregnancy.

Euploid Embryo

Meaning

A Euploid Embryo is an embryo that possesses the correct, complete number of chromosomes, specifically 46 chromosomes in humans, consisting of 22 pairs of autosomes and one pair of sex chromosomes. Chromosomal normalcy, or euploidy, is the single most significant factor dictating the developmental potential of an embryo. In the context of in vitro fertilization, euploid embryos identified via preimplantation genetic testing (PGT-A) are associated with the highest rates of successful implantation and live birth.
