👉 The southern fluid, also known as prostatic fluid or urethral fluid, is a complex mixture produced by the prostate gland located in the male reproductive system. It plays a crucial role in maintaining the health and function of the urethra, the tube that carries urine and semen out of the body. This fluid is rich in enzymes, particularly prostate-specific antigen (PSA), and contains proteins that help to lubricate the urethra, facilitating smooth urine flow and protecting the delicate tissues of the urinary tract from irritation. The composition of the southern fluid is essential for male reproductive health, as it aids in sperm transport and contributes to overall prostate function.
