Loss of sex drive is a classic symptom of depression according to depression.com. About 75% of depressed individuals report it.
Of the other 25%, most report no change in libido, and some experience
unusually intense sex drive. But typically, people who are depressed lose
their libido.
However, depressed individuals generally regret their loss of libido and miss sex. Researchers have asked depressed and nondepressed people: How
important is a good sex life to you? About 70% of both groups reply: very. In other words, people who are depressed value sex, but the disease prevents them from enjoying it.
