They are highest in the early morning (between 4:00\u20138:00 AM) and gradually decrease by evening. For this reason, blood tests should be done in the morning for the most reliable results.  <\/span><\/p>\n<h3><span style=\"color: #000000;\"><b>Can diet affect testosterone levels by age?<\/b><\/span><\/h3>\n<p><span style=\"font-weight: 400; color: #000000;\">Although testosterone production is tightly regulated by the brain (hypothalamus-pituitary axis), diet can indirectly help maintain normal levels.<\/span><\/p>\n<p><span style=\"font-weight: 400; color: #000000;\">The Mediterranean diet, rich in healthy fats (olive oil, nuts), proteins (fish, legumes), and complex carbs (whole grains), seems to better support hormonal balance compared to low-fat diets. A lack of dietary fat can impair hormone production. <\/span><\/p>\n<h3><span style=\"color: #000000;\"><b>Can testosterone levels be increased naturally?<\/b><\/span><\/h3>\n<p><span style=\"font-weight: 400; color: #000000;\">No, at least not safely and permanently without medical intervention.

Except in medically diagnosed cases of hypogonadism, testosterone should only be taken under medical supervision and prescription. <\/span><\/p>\n<h3><span style=\"color: #000000;\"><b>Medical administration of testosterone to restore normal levels of testosterone by age<\/b><\/span><\/h3>\n<p><span style=\"font-weight: 400; color: #000000;\">If it is medically confirmed that testosterone levels are indeed low, then the option of <a href=\"https:\/\/www.mentest.gr\/en\/\" target=\"_blank\" rel=\"noopener\"><strong>testosterone increase<\/strong><\/a> through exogenous hormone administration can be considered. In such cases, testosterone replacement therapy (<a href=\"https:\/\/www.mentest.gr\/en\/trt-en\/\" target=\"_blank\" rel=\"noopener\"><strong>TRT therapy<\/strong><\/a>) may be evaluated, with the goal of restoring testosterone to normal levels and improving quality of life. MenTest is a specialized medical center in Greece dedicated to addressing low testosterone and its effects on men&#8217;s health. The medical team, led by specialist andrologist-urologist Dr. Christos Fliatouras, applies modern therapeutic methods tailored to each patient\u2019s needs, aiming to improve quality of life and overall well-being.    <\/span><\/p>\n<p><span style=\"font-weight: 400; color: #000000;\">In conclusion, testosterone is a crucial hormone for men&#8217;s overall health. Testosterone levels vary with age and are influenced by many factors. In men, a natural decline after the age of 30 is expected; however, when the drop is significant and accompanied by symptoms, medical evaluation is warranted.  <\/span><\/p>\n<p><span style=\"font-weight: 400; color: #000000;\">If you are seeking information about the recommended testosterone levels by age, make sure to consult an endocrinologist or urologist. Do not trust unapproved supplements or questionable treatments that have not been prescribed by a specialist. <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Testosterone is a key hormone for both men and women, although its roles andnormal levels differ significantly depending on sex and age.
