Bulbourethral Gland Tumors

Bulbourethral gland tumors are rare growths that develop in the bulbourethral glands, also known as Cowper’s glands. These small glands are part of the male reproductive system and play a role in producing pre-ejaculate fluid. Understanding bulbourethral gland tumors is crucial for early detection and effective treatment. This guide provides detailed information about these tumors, including their structure, causes, symptoms, diagnosis, treatment options, prevention, and frequently asked questions.

Bulbourethral glands, or Cowper’s glands, are two small glands located below the prostate gland in males. They secrete a clear fluid that lubricates the urethra for sperm to pass through during ejaculation.

Structure and Location

• Structure: Each gland is about the size of a pea and consists of glandular tissue.
• Location: Positioned on either side of the urethra, beneath the prostate gland.

A bulbourethral gland tumor is an abnormal growth in one or both of the bulbourethral glands. These tumors can be benign (non-cancerous) or malignant (cancerous).

Types of Bulbourethral Gland Tumors

1. Benign Tumors:
   • Adenomas
   • Papillomas
2. Malignant Tumors:
   • Adenocarcinomas
   • Squamous cell carcinomas
   • Sarcomas

Pathophysiology

Structure

Bulbourethral glands consist of glandular tissue responsible for producing seminal fluid. The glands have ducts that empty into the urethra.

Blood Supply

• Arteries: Bulbourethral arteries supply blood to the glands, originating from the internal pudendal artery.
• Veins: Drainage occurs through the bulbourethral veins into the internal pudendal veins.

Nerve Supply

• Autonomic Nerves: Provide involuntary control over gland secretion.
• Somatic Nerves: Responsible for voluntary control related to ejaculation.

While bulbourethral gland tumors are rare, several factors may contribute to their development:

1. Genetic mutations
2. Family history of cancer
3. Exposure to carcinogens
4. Chronic inflammation
