How can depression effect sexual function?

I'm interested in information as to how sexual function can be affected by depression, especially in males. I have read it can harm libido. Can it harm it in other ways as well? If so, what are these ways?

I ask because I am a depressed male experiencing not only impotence and low libido but low genital sensitivity and anorgasmia as well. Can depression cause these things, or should I be looking for some other cause? Please provide citation if at all possible.

I am not interested in how psychiatric medications might affect these areas, just depression.

Thanks

Well when you are depressed,there is really not a whole lot you care about or are interested in.
And sex is not on your priority list of things to do.
To pass a day is big enough without the hassle of dealing with sex as well.
Your life is on a standstill.
Nothing excites you:hence the impotence,low sex drive,low sensitivity etc.
So yes depression can cause all of this.
I feel sorry for you:
