Propecia, does it affect behaviour

[MICHAEL]

I know Propecia works by affecting the testosterone receptors in the scalp. But I also know how much hormones affect behaviour. So does Propecia's effects on testosterone have any effects on behaviour, or other things that are affected by testosterone?

[John N]

yeah, you loose your libido--you don't want sex.

and possibly can't get it up.

So, your choice...............you can have hair, or you can have sex. I know which one I'd choose.

The only side effect from Propecia I know that is related to behavior is decreased libido. There are articles which say that finasteride (the generic drug of Propecia) is associated with depression but there's no enough proof to say so.
