Corpus cavernosum dysfunction refers to problems with the two sponge-like regions of erectile tissue found in the penis. These issues can lead to difficulties in achieving or maintaining an erection, impacting sexual health and overall quality of life. This guide provides detailed descriptions, definitions, causes, symptoms, diagnostic methods, treatments, and preventive measures related to corpus cavernosum dysfunction,

The corpus cavernosum consists of two cylindrical structures in the penis that fill with blood during an erection, enabling sexual intercourse. Dysfunction in these structures means they aren’t working properly, leading to challenges like erectile dysfunction (ED), pain, or other penile issues.

Pathophysiology

Structure

  • Corpus Cavernosum: Two main columns of erectile tissue running along the penis.
  • Tunica Albuginea: A tough fibrous layer surrounding the corpus cavernosum, helping maintain erections by trapping blood.

Blood Supply

  • Arteries: Supply blood to the penis, particularly the dorsal and deep arteries.
  • Venous Drainage: Blood exits through veins; proper function ensures sustained erections.

Nerve Supply

  • Autonomic Nervous System: Controls blood flow during erection and ejaculation.
  • Somatic Nervous System: Manages sensation and voluntary movements.

Types of Corpus Cavernosum Dysfunction

  1. Erectile Dysfunction (ED): Inability to achieve or maintain an erection.
  2. Priapism: Persistent and often painful erections lasting hours.
  3. Penile Fibrosis: Scar tissue formation leading to curvature and pain.
  4. Venogenic Erectile Dysfunction: Blood leaks from the corpus cavernosum, preventing erection.
  5. Neurogenic Erectile Dysfunction: Nerve damage affecting erection.
