Prostate Gland

Definition

The prostate gland is a small, walnut-sized exocrine gland located at the base of the bladder in males. It is an essential part of the male reproductive system, responsible for producing a key component of seminal fluid that nourishes and transports sperm.

5 Must Know Facts For Your Next Test

1. The prostate gland produces a fluid that makes up about 30% of the volume of semen, which helps nourish and protect sperm.
2. The prostate gland surrounds the urethra, the tube that carries urine from the bladder out of the body, as well as semen during ejaculation.
3. As men age, the prostate gland commonly becomes enlarged (benign prostatic hyperplasia or BPH), which can lead to difficulty urinating and other lower urinary tract symptoms.
4. Prostate cancer is one of the most common cancers in men, and regular screening through prostate-specific antigen (PSA) testing and digital rectal exams are important for early detection.
5. The prostate gland is located just below the bladder and in front of the rectum, making it accessible for physical examination and various medical procedures.

Review Questions

• Describe the primary functions of the prostate gland within the male reproductive system.
  • The prostate gland plays a crucial role in male reproduction by producing a fluid that makes up a significant portion of the seminal fluid. This fluid helps nourish and transport sperm during ejaculation. Additionally, the prostate gland surrounds the urethra, the tube that carries both urine and semen out of the body, allowing it to contribute to the overall function of the male urinary and reproductive systems.
• Explain the relationship between the prostate gland and the development of benign prostatic hyperplasia (BPH) in older men.
  • As men age, the prostate gland commonly becomes enlarged, a condition known as benign prostatic hyperplasia (BPH). This enlargement can lead to the prostate gland putting pressure on the urethra, which passes through the center of the gland. This pressure can cause difficulty urinating and other lower urinary tract symptoms, such as a weak urine stream, frequent urination, and a feeling of incomplete bladder emptying. Understanding the anatomical relationship between the prostate gland and the urethra is crucial for recognizing and managing the development of BPH in older men.
• Discuss the importance of regular prostate cancer screening for men and how the location of the prostate gland facilitates various medical procedures.
  • Prostate cancer is one of the most common cancers in men, and regular screening through prostate-specific antigen (PSA) testing and digital rectal exams are essential for early detection and treatment. The prostate gland's location just below the bladder and in front of the rectum makes it accessible for these screening procedures, as well as other medical interventions, such as biopsy and various surgical treatments. The strategic positioning of the prostate gland within the male pelvic anatomy allows healthcare providers to effectively monitor, diagnose, and manage conditions related to this important reproductive organ.
