Reverse causation is not ruled out because diagnosis can be delayed.
It seems entirely plausible to me that it takes several months of worsening depression symptoms (during which time sex drive is effected) before a patient sees a psychiatrist.
I suppose it’s ruled out if we separate “depression” and “diagnosed with depression” into separate nodes, but that doesn’t rule out anything interesting.
