The prostate gland, a small walnut-shaped gland found in men, is situated below the bladder and around the urethra. It produces a seminal fluid that protects the sperm. Some men experience prostate problems as they age. This is mainly because over the course of time, the prostate expands and presses against the bladder and urethra. This obstructs urinary flow and can also interfere with ejaculation. Men can avoid or delay the onset of such conditions by taking the following steps to maintain a healthy prostate.
