Does ginkgo biloba increase testosterone?

Ginkgo is not an established testosterone booster. Claims about circulation, antioxidant activity or sexual function do not demonstrate a sustained hormone increase or a treatment for testosterone deficiency. The inspected NCCIH evidence summary does not establish this use.

Define the claimed benefit

An improvement in a symptom, blood-flow measurement or laboratory marker is not automatically a rise in testosterone. Treating a hormone disorder requires evidence for that specific outcome and population. [1][2]

Do not transfer unrelated research

Ginkgo has been investigated for several health purposes, but NCCIH reports no conclusive evidence of benefit for any condition. Results involving memory or other outcomes cannot establish a testosterone regimen. [1]

A hormone claim does not remove risk

Leaf extracts may cause digestive symptoms, headache or dizziness, and bleeding interactions are important. Toxic seeds and crude preparations are not a substitute for studied extracts. No hormone benefit should be presumed to outweigh these risks. [1]

Investigate persistent symptoms

Imagine reduced libido leads someone to buy a ginkgo testosterone blend. Discuss symptoms and whether testing is appropriate with a clinician, and review all blend ingredients. A marketing phrase cannot diagnose the cause or establish a useful dose. [2][1]
