How does Vitex work?

[Tha X]

So how does Vitex actually work? It is said it will avoid menstrual pain for women and such. But how does it actually work for men? What mechanism does it have?

Does it work like SERM or AI or something completely different?

And will they look wierd at me when going to buy it as it's for women under name Prefemin?

Bump.
