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.
Estrogen and progestin are typically prescribed together when a woman still has her uterus to reduce the risk of uterine cancer while promoting the benefits of estrogen therapy. Yet estrogen alone is used in women whoâve had a hysterectomy, or removal of the uterus.
