Introduction
Traditional Chinese medicine holds that the liver governs the smooth flow of qi. Prolonged excess liver fire can lead to emotional imbalances, causing irritability and anxiety, which in turn disrupt neuroendocrine regulation and impair reproductive system function, potentially resulting in decreased libido and erectile dysfunction. Meanwhile, excessive liver fire may also trigger discomforts such as insomnia and dry mouth, indirectly weakening overall physical condition and affecting sexual function.

Under normal circumstances, excessive liver fire may indirectly lead to decreased sexual function. Prolonged excessive liver fire has a more noticeable impact, while short-term mild symptoms usually do not cause significant effects. If concerned, it is recommended to seek medical advice early. The detailed analysis is as follows:

In traditional Chinese medicine, the liver governs smoothing and regulating functions. Chronic excessive liver fire can lead to emotional imbalances such as irritability and anxiety, thereby affecting neuroendocrine regulation and interfering with reproductive system function. This may manifest as reduced libido, poor erectile quality, and other symptoms. Additionally, excessive liver fire may cause discomforts such as insomnia and dry mouth, indirectly weakening overall physical condition and impairing sexual function.

If the excessive liver fire is only mild and short-term, and promptly alleviated through dietary and lifestyle adjustments, the body's regulatory functions can quickly recover, generally without causing obvious impact on sexual performance. Decreased sexual function is more commonly associated with long-standing unresolved liver fire combined with other health issues, rather than being caused by a single factor alone.

When symptoms related to excessive liver fire occur, timely improvements through a light diet, regular作息 (daily routine), and emotional regulation are recommended. If sexual dysfunction persists, a comprehensive medical evaluation is advised to identify the underlying causes.
