Transvaginal ultrasound aspiration.

An ultrasound-guided technique for egg retrieval. A long, thin needle is passed through the vagina into the ovary. When the follicle is entered, suction is applied to retrieve the eggs. It is also known as ultrasound-guided egg aspiration and transvaginal egg retrieval.

Trophoblast.

These are the cells of the embryo that become the placenta and attach the baby to the mother's uterus. These cells provide an armor of protection completely around the baby in the uterus. They also serve to nourish the baby carrying food from the mother's blood to the babies blood. These are the cells that are biopsied during a chorionic villus biopsy (CVS) to determine if the baby is genetically normal.
