On the other hand, a sedentary lifestyle, poor sleep, and exposure to endocrine-disrupting chemicals can negatively impact testosterone levels. In some cases, high testosterone levels can be a result of tumors or cysts on the testes or ovaries, which can produce excess testosterone. Additionally, medical conditions such as polycystic ovary syndrome (PCOS) or Cushing’s syndrome can also lead to elevated testosterone levels. For example, individuals with a family history of hormonal imbalances or certain genetic disorders, such as congenital adrenal hyperplasia, may be more likely to experience high testosterone levels. Laboratories may have different reference ranges for normal testosterone levels. If you’re getting a total testosterone blood test, you may need to get it in the morning since testosterone levels are highest then. Low levels may indicate a delay in sexual development. A testosterone test is a blood test that measures your levels of testosterone, a hormone. Following a nutritious diet and healthy lifestyle using some of the tips outlined above can help optimize testosterone levels and promote overall health. Testosterone levels in males peak at 19 years and naturally decline with age. Low testosterone levels for adult premenopausal females are 10 to 55 ng/dL, and for postmenopausal females, 7 to 40 ng/dL. Adequate testosterone levels are essential for muscle maintenance, strength, and recovery. It’s natural for testosterone levels to vary depending on your age and overall health. Late-onset male hypogonadism happens when the decline in testosterone levels is linked to general aging and/or age-related conditions, particularly obesity and Type 2 diabetes. Classical male hypogonadism is when low testosterone levels are due to an underlying medical condition or damage to your testicles, pituitary gland or hypothalamus. Professional blood testing is essential before making any changes — symptoms alone do not confirm low testosterone. Levels naturally decline with age, but lifestyle factors, stress, body composition, and nutrient status can influence them further. Not everyone with low testosterone has symptoms (like low sex drive, fertility problems or erectile dysfunction). The only way to know your testosterone level is with a blood test. "Normal" ranges for testosterone also vary significantly based on your age and sex. Testosterone is often referred to as the "male hormone" due to its significant effects on the male body, but it is also present in females, albeit at lower levels, where it contributes to the regulation of the menstrual cycle, fertility, and overall health. While exceptionally high testosterone levels can confer advantages in terms of physical performance, they also come with potential health risks. Beyond its well-known effects on reproductive and sexual health, testosterone influences bone density, muscle mass, and the distribution of body fat. In a 2021 study, zinc supplementation increased testosterone levels and improved sexual function in postmenopausal women with low blood levels of zinc. In adult males, healthy levels are important for general health, including disease risk and sexual function. Lower-than-normal testosterone levels typically only cause symptoms in males. Testosterone is synthesized in the body from cholesterol. If you thought testosterone was only important in men, you'd be mistaken. There may be other important functions of this hormone that have not yet been discovered. Testosterone may also help maintain normal mood. The pituitary gland then relays signals to the testes to produce testosterone. Signals sent from the brain to the pituitary gland at the base of the brain control the production of testosterone in men.
