The blastocoel migration is a crucial process in embryonic development, occurring between the fourth and sixth day after fertilization. At this stage, the embryo, in the form of a blastocyst, moves through the fallopian tube to reach the uterus, where it prepares for implantation. This displacement is accompanied by continuous growth, and the embryo depends on its nurse cells for its initial survival.
Implantation usually occurs in the anterior part of the uterus, near the bladder, an area chosen for its warmth. The uterine lining plays an essential role by becoming welcoming to the embryo, thickening and vascularizing to provide an environment rich in blood, sugar, electrolytic activities, and an early supply of oxygen. These elements are indispensable for supporting embryonic development, thus marking a decisive step in pregnancy. Implantation itself will be discussed later, highlighting the importance of this phase in the gestation process.
