When testosterone is too high in men, there are usually no obvious clinical signs in adult males, and pubertal males may show precocious puberty. Testosterone is the androgen hormone. In adult males with elevated testosterone, there are usually no obvious changes. Some patients may only show changes in heart rate, vigorous body hair, more beard, increased libido, and exuberant sebaceous gland secretion. In adolescent males with hyperandrogenism, it can manifest as precocious puberty, which will make the secondary sexual characteristics more obvious, such as a thicker voice, faster growth in height than peers, more muscular, and even very early appearance of pubic and axillary hair, obvious development of the laryngeal nodes, and a quick temper, an irritable personality, and a strong aggressiveness. If testosterone is found to be too high, you should go to the hospital for a more comprehensive examination.
