What is hard flaccid syndrome?
Hard flaccid syndrome is characterized by chronic pain in the penis and perineum (the area between the genitals and the anus). The penis is also semi-rigid, even when it is flaccid (not erect).
Scientists have not yet developed an evidence-based definition of hard flaccid syndrome, and they continue to study it. Researchers have analyzed patient case reports and internet forums to learn more. However, it is not known how common this condition is.
Men with hard flaccid syndrome may experience the following symptoms:
- Pain, especially when standing
- Firmness or rigidity in the penis when it is flaccid (not erect)
- Fewer morning erections
- Numbness, coldness, or a “hollow” feeling in the penis
- Erection difficulties, especially when a man is standing
- A need for more stimulation to achieve an erection
- Painful ejaculation
- Painful urination
For some men, symptoms are worse during times of stress.
The actual cause of hard flaccid syndrome is not clear. Some men have reported that symptoms began after trauma to the penis during intercourse or vigorous masturbation.
Treatment may include medications for pain management, pelvic floor physical therapy, biofeedback, and stress reduction techniques. Men experiencing anxiety or depression may benefit from counseling.
