5 min read ASK A UROLOGIST , and they’ll tell you that the prostate has two functions: one is to secrete fluids that come out with ejaculation. The other is to keep urologists in business. That’s a lot of work for a doughnut-shaped gland roughly the size of a cherry tomato. You might think it’s cancer keeping all those docs busy, since prostate cancer is by far the most common cancer diagnosis in men. But there is still a virtually universal prostate issue: The gland never stops growing. The prostate sits under the bladder, and the urethra (the tube that carries pee out of your bladder) passes right through the doughnut hole. A larger prostate puts pressure on the urethra and makes it hard to pee, which is annoying and can lead to other issues, like bladder infections. Fortunately, regular exercise and healthy eating moves can help counter the risk of prostate issues. Don’t wait to lock in these habits: Young guys can experience an enlarged prostate, too.…
