Chapter 43: Disorders of the Male Reproductive System

Benign prostatic hyperplasia represents a common non-malignant condition characterized by excessive growth of prostatic tissue organized into distinct nodular formations that progressively enlarge the gland without crossing tissue boundaries. The mechanical consequence of this enlargement involves compression of the prostatic urethra, which substantially reduces urine flow and creates bothersome lower urinary tract symptoms. The chapter distinguishes the histological and clinical presentations among normal prostatic tissue, benign hyperplastic changes, and malignant neoplasms, establishing critical diagnostic differentiation skills essential for clinical practice. Prostate-specific antigen testing receives detailed attention regarding its application in pre-treatment evaluation to determine cancer stage and extent of disease, as well as its role in post-treatment surveillance to monitor for recurrence or treatment failure. The chapter also addresses inflammatory and infectious conditions of the prostate, particularly acute bacterial prostatitis, covering its typical clinical manifestations, diagnostic approaches including laboratory and imaging studies, and evidence-based management strategies. Understanding the anatomical relationships between the prostate and surrounding urinary structures provides context for how enlargement or inflammation produces urinary obstruction and symptomatology. The content integrates morphological, biochemical, and clinical dimensions to help students recognize disease patterns and apply appropriate assessment and management principles for patients presenting with prostatic pathology.
