It is rarely just testosterone
Libido is a composite signal: hormones, neurotransmitters, vascular health, sleep, relationship dynamics, and medication side effects all participate.
The eight drivers
1. Low free testosterone. 2. Elevated prolactin. 3. SSRIs and certain blood-pressure medications. 4. Chronic sleep deprivation. 5. Chronic stress and high cortisol. 6. Relationship dynamics. 7. Excess alcohol. 8. Pornography habituation in some cases.
Frequently asked questions
- Does pornography really affect libido?
- High-frequency consumption can dampen real-world arousal response in some men. Reducing for 6-8 weeks is a defensible experiment.
- What about prolactin?
- Elevated prolactin suppresses both testosterone and libido. Worth testing if libido is unusually flat.
