The crus of the penis refers to the two elongated structures on either side of the penis, part of the corpora cavernosa. These structures play a crucial role in achieving and maintaining an erection by supplying blood to the penis. Obstruction in this context means a blockage or hindrance in the normal blood flow within the crura, which can lead to various medical issues, including erectile dysfunction and pain.
Pathophysiology
Structure
- Crura of the Penis: The crura are two cylindrical structures located at the base of the penis. They are part of the corpora cavernosa, which are spongy tissues that fill with blood during an erection.
- Blood Supply: The crura receive blood from the deep arteries of the penis, ensuring sufficient blood flow for erectile function.
- Nerve Supply: Nerves in the crura control the blood flow and help in the sensation and erection process.
How Obstruction Occurs
An obstruction can occur due to:
- Physical Blockages: Such as scar tissue or tumors that impede blood flow.
- Vascular Issues: Conditions like atherosclerosis that narrow or block blood vessels.
- Nerve Damage: Affecting the signals that control blood flow.
Types of Crus of Penis Obstruction
- Vascular Obstruction: Blocked blood vessels reducing blood flow.
