Penile congestion refers to a state in which the blood vessels in the cavernous body of the penis expand and blood inflow increases, resulting in an increase in penis size and hardening. This is a key link in the erection process and one of the manifestations of normal male sexual function.

| Pathological congestion | Priapism (lasting more than 4 hours), inflammation, or trauma |
| external factors | Drug side effects (such as antidepressants), vascular disease, etc. |
3. Physiological mechanism of penile congestion
The process of penile engorgement involves complex neuro-vascular regulation:
| stage | Physiological changes |
|---|---|
| excitement period | The brain or local nerves are stimulated to release nitric oxide (NO) |
| hyperemic period | Cavernous arteries dilate and blood inflow increases 3-5 times |
| maintenance period | The tunica albuginea compresses the veins and reduces blood return |
| regression period | Sympathetic nerve excitement, vasoconstriction, and blood reflux |
