loss of sexual desire and / or diminished sexual response is a common side-effect of psychiatric medications.

sometimes i wonder if it is (at least partially) an intentional side effect. an attempt to reduce the mentally ill population in future years or something like that. i think that is crediting the drug developers with a little too much, however. firstly because it is in their interests to have future consumers and secondly because the drugs simply aren't specific enough in their effects for them to be able to do much about it.

the main mechanism seems to be a kind of sedation. that seems to be precisely the mechanism that helps people. precisely that mechanism is what results in less distress (along with less creativity less passion less sexual desire etc etc etc). bit of a package deal with the psychiatric medications methinks...
