The prostate gland is a small, walnut-sized organ located below the bladder in men. It surrounds the urethra, the tube that carries urine and semen out of the body. The primary function of the prostate is to produce a fluid that nourishes and transports sperm during ejaculation. This gland plays a crucial role in male reproductive health. As men age, the prostate can enlarge, leading to conditions such as benign prostatic hyperplasia (BPH) or prostate cancer. Regular check-ups and awareness of symptoms are important for maintaining prostate health.
