I wanted a 2nd opinion about whether sexual problems could be caused by depression -- or something else. A psychiatrist diagnosed depression, but I'm still not convinced as most of my symptoms are physical and I haven't experienced a major mood change. I've had thorough blood work done but my doctors didn't find anything they thought significant (a brain MRI showed vascular lesions, but they said they couldn't diagnose anything based on this and ruled out MS).
My symptoms began 4 years ago without any triggering incident: Fatigue, weakness, mental fog, light headedness, loss of libido, erection difficulties (no full erections), including loss of involuntary erections while asleep, and loss of pleasure from sex. Otherwise my life feels quite normal. I don't take any medications.
As far as I know, loss of libido is normal with depression or chronic fatigue syndrome but not the loss of erections. Any ideas about whether depression could cause this? Or anything else? If it is depression, is the best way to get relieve these physical symptoms by taking anti-depressants (even though they can cause these symptoms)? I've been pretty thoroughly tested but is there anything else I could investigate?
