What is the term for the process whereby an embryo attaches itself to the uterus wall?

The term for the process whereby an embryo attaches itself to the uterus wall is implantation. This is a critical step in early pregnancy; it occurs after fertilization and the embryo's development into a blastocyst. The blastocyst travels through the fallopian tube and into the uterus, where it must attach to the uterine lining (endometrium) to establish a connection that will allow for nutrient and waste exchange with the mother. Successful implantation is essential for the embryo to receive the necessary support to grow and develop into a fetus.

Ovulation refers to the release of an egg from the ovary and is a part of the menstrual cycle, while menstruation is the process of shedding the uterine lining when pregnancy does not occur. Gestation describes the period of development of the embryo and fetus in the uterus, starting from implantation until birth, but does not specifically refer to the attachment process itself.
