Prostate-Specific Antigen (PSA)

Abstract

Prostate-specific antigen (PSA) is produced by the prostate gland. PSA plays a crucial role in reproductive health by maintaining the liquidity of semen, which is essential for sperm mobility and successful fertilization. Beyond its biological functions, PSA testing has become an integral part of diagnosing and managing conditions like prostate cancer, offering insights into the presence and progression of the disease. This patient education book aims to explore the diverse aspects of PSA, from its functions to its broader implications in medicine. It first outlines the biological function of PSA, illustrating its significance in reproduction. The discussion then shifts to the practical applications of PSA in the medical field, specifically focusing on PSA testing, which measures the level of PSA in the blood to help detect and monitor prostate conditions. This includes an exploration of what normal and abnormal PSA levels mean and how they are interpreted in clinical settings. The broader medical uses of PSA, including its role in cancer screening and the controversies surrounding its use, are also covered. This comprehensive approach aims to provide a clear and detailed understanding of PSA, underscoring its importance in healthcare and the ongoing efforts to optimize its use for better patient outcomes. While primarily designed for patients, their families, and caregivers, this information also serves as a valuable resource for researchers, especially those early in their careers, who have an interest in this field.
