Which gland is known to enlarge in males as they age?

The prostate gland is known to enlarge in males as they age due to a condition called benign prostatic hyperplasia (BPH). This is a common phenomenon where the cells of the prostate gland multiply, leading to an increase in size. As men get older, hormonal changes, particularly the levels of testosterone and dihydrotestosterone, contribute to this enlargement.

The prostate's enlargement can lead to various urinary symptoms, including difficulty in starting to urinate, increased frequency of urination, and a sensation of incomplete bladder emptying. Understanding this condition is essential for recognizing the physiological changes that occur in men's health as they age.

Other glands, like the adrenal gland and thyroid gland, have different functions and do not typically exhibit the same characteristic growth associated with aging in males. The thoracic gland, not commonly referred to in this context, does not relate to male aging. Therefore, the prostate gland stands out as the gland that specifically enlarges in males with age.
