Why is sex tied to depression?

Depression affects sex because of biology. It starts with chemicals in the brain called neurotransmitters. Neurotransmitters communicate between your brain, where sexual desire starts, and your sex organs. When your brain thinks desire, your body responds by increasing blood flow to the sex organs. Increased blood flow triggers arousal through an erection or vaginal lubrication.

In a person with depression, the sex-related chemicals are out of balance. As a result, sexual desire is low or missing. Low levels of some of these chemicals can also dull pleasurable feelings.
