The adaptations of the sperm and egg that allow fertilization to take place, and copulation occurs for the sperm to be deposited. These sperm penetrate the cervix and travel to the fallopian tube. There, they must find an oocyte, which is released in the process of ovulation.
<h3>What is fertilization and embryo development?</h3>
In the first weeks after fertilization, the zygote makes many changes and develops rapidly. The first eight weeks of development is known as the organogenic period and is the embryonic stage of development. This period is a crucial phase of development for the embryo's organs.
With this information, we can conclude that The first three days of embryonic development occur in the fallopian tube as the embryo moves from the ovary to the uterus. Cell division continues and forms a hollow ball of cells (the blastocyst). Six days after fertilization, the embryo begins implantation into the lining of the uterus.
