What may result from prolonged priapism if not treated?

Prolonged priapism, which is a persistent and often painful erection not associated with sexual desire or stimulation, can lead to severe complications if not treated. One of the most significant potential outcomes is persistent erectile dysfunction. This occurs due to ischemic damage to the penile tissues. When blood pools in the penis for longer durations, it deprives the tissues of oxygen, leading to necrosis and irreversible damage.

The other outcomes listed do not occur as a direct consequence of untreated priapism. While increased blood pressure can result from various stressors, it does not specifically relate to the condition of priapism. Similarly, there is no evidence to suggest that priapism leads to enlargement of the penis or enhanced libido, as both of these conditions are unrelated to the pathological process of prolonged priapism. The primary concern remains the potential for erectile dysfunction, making it crucial for timely intervention to prevent long-term consequences.
