Depression and libido loss: what should you know?

Depression can affect interest, arousal, orgasm, and the sense of connection that supports intimacy. Low energy, poor sleep, anxiety, difficulty concentrating, or feeling numb may reduce desire even when a relationship is caring. Some antidepressants and other medicines can also affect sexual function. Hormone changes, pain, alcohol or substance use, thyroid problems, and relationship stress are additional possibilities. Libido loss does not identify one cause by itself. Notice whether the change began with low mood, a new medicine, a physical symptom, or a major life event.

Book a private appointment if the change is troubling, persistent, or affecting a relationship. Bring a list of medicines and describe desire, arousal, orgasm, pain, sleep, and mood changes. Do not stop an antidepressant suddenly; a clinician can review the dose, timing, alternatives, and the balance between mood benefits and sexual side effects. Gentle communication with a partner can reduce pressure: explain that reduced desire is a health concern, not necessarily a sign of rejection. Treatment for depression, counselling, relationship support, or assessment of a physical cause may each have a place.

Seek medical advice when libido loss comes with persistent sadness, loss of interest, marked fatigue, sleep disruption, pain during sex, erectile or vaginal changes, or a sudden change after starting medicine. Get urgent help if depression includes thoughts of suicide or self-harm, inability to stay safe, or loss of contact with reality. Contact local emergency services or the nearest emergency department, and stay with someone you trust while help is arranged.

Ask: Could depression, my medicine, or a physical condition be affecting desire? What changes are safe to try? How should we monitor mood if treatment changes? Could pain, hormones, sleep, or anxiety be contributing? What support is available for me and my partner?
