It activates prolactin receptors which I think increases progesterone. BE requires estrogen in the presence of progesterone, but progesterone also decreases estrogen. Hence why it could help some and hurt others, or after too much or a long time hurt everyone. So you should get phytoestrogens as well. But the only way to know for sure which you need more of is a hormone test. A balance is also better for your health. Those with feminine problems tend to benefit the most from progesterone, whereas those with too much tend to be more asexual. Too much estrogen is more common, and those with these problems who only take phytoestrogen herbs tend to see them worsen.

Prolactin (but not progesterone) also decreases dopamine which could affect mood in some people.
