Which lobe of the prostate is most likely to be enlarged in benign prostatic hyperplasia (BPH)?

• A. Lateral lobe
• B. Median lobe
• C. Inferior lobe
• D. Posterior lobe

Answer: (B)

In benign prostatic hyperplasia (BPH), the most commonly affected area of the prostate is the median lobe. This condition involves non-cancerous enlargement of the prostate gland, primarily due to hyperplasia (increased number of cells) in glandular tissue. As the median lobe enlarges, it can protrude into the bladder neck, potentially causing obstruction of urinary flow, which is a hallmark symptom of BPH. This anatomical positioning makes the median lobe critical in understanding urinary symptoms often associated with the condition. Other lobes, while they may contribute to enlargement, do not typically have the same clinical implications as the median lobe in the context of BPH. Therefore, recognizing the significance of the median lobe is essential in diagnosing and managing symptoms associated with benign prostatic hyperplasia.
