AC is when the electrons flow in two directions, from the positive to the negative terminal and from the negative to the positive terminal, 'alternating' between the two directions. (Your lights will light up regardless of the direction of the electron flow.) A lot of people think of electron flow as electrons moving along a wire freely like cars go down a highway. Actually, it works a little differently. Any conductor (thing that electricity can go through) is made of atoms.
Natural progesterone is know to be protective against heart disease and women after hysterectomy have no progesterone to balance their bodies continuing production of oestrogen â a situation which can lead to symptoms of oestrogen dominance â and fibroids are known to be cause by excess oestrogen.
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.

That's because estrogen alone can increase the risk of cancer in the uterus. Adding progestin removes this risk.omen who have both the uterus and ovaries removed usually just get estrogen replacement therapy (ERT) alone.
