Blastocyst

The blastocyst is one of the first stages of human embryo development. It is formed as a result of the fusion of two gametes (sperm and egg) and subsequent division of cells that form the embryo.

The blastocyst has the shape of a vesicle and contains all the cells necessary for the development of the embryo. It contains a layer of cells called trophoblast that will develop into the placenta. Also inside the blastocyst are the cells that will form the embryo.

After the formation of the blastocyst, it begins to migrate into the uterine cavity. There it attaches to the wall of the uterus and begins to grow and develop. The blastocyst can remain in the uterus for up to 10 days, after which it turns into an embryo and begins to develop further.

It is important to note that the blastocyst is very sensitive to external factors such as hormones, infections and other factors that can affect its development. Therefore, in order to avoid possible complications, it is necessary to monitor your health and lifestyle, as well as undergo regular medical examinations.
