Hormone therapy after surgery -- either with estrogen and progestin or with estrogen alone -- is a way to counteract the supply of estrogen you've lost. Women who have both the uterus and ovaries removed usually just get estrogen replacement therapy (ERT) alone. But women who have only the ovaries removed need both estrogen and progestin. That's because estrogen alone can increase the risk of cancer in the uterus. Adding progestin removes this risk.
Tauriel is a fictional character from Peter Jackson's feature film adaptation of J.R.R.
Tau is a protein found in neurons, where it works to stabilize the shape and function of the cell. As part of normal function, proteins in the body fold, unfold and refold into different shapes in order to perform specific functions, and when they are no longer needed, they are broken down and recycled by the cell.
