Final answer:
The prostate gland is palpable in older males particularly due to the common enlargement of the gland with age, known as benign prostatic hyperplasia (BPH).
Step-by-step explanation:
The gland that can be palpated (found in older males) is the prostate gland. The prostate gland is not readily palpable in younger males, but as males age, it often enlarges, a condition known as benign prostatic hyperplasia (BPH), which can make it more palpable during a medical exam. While other glands, such as the thyroid gland, are also palpable, they are not associated with changes specific to older males.
