High testosterone in males: Signs and symptoms High testosterone in males: Signs and symptoms If a product says it is going to “raise your testosterone level,” that’s a medical claim. If you have one or more of the above symptoms, we will measure your testosterone level with a blood sample. Testosterone levels naturally decrease as men grow older, but at a very slow, almost unnoticeable rate (around 1% loss each year, after about the age of 30). Testosterone is crucially important to men during puberty, but becomes relatively less important in later years, hence its declining levels in the body. When reviewing results from meta-analyses, it is important to recognize that the overall reliability is dependent on the quality of the weakest study included in the analysis. For example, outcomes of meta-analyses using RCTs alone are generally more robust than those that also include cohort studies. Meta-analyses that are limited to only including RCTs may be restricted to a small number of studies and relevant studies may be excluded that could provide sufficient power to make alternative conclusions. Some doctors suggest that monitoring testosterone levels every five years, starting at age 35, is a reasonable strategy to follow. If the testosterone level falls too low or if the individual has the signs and symptoms of low testosterone levels described above, testosterone therapy can be considered. Testosterone is considered to be the “male hormone” that’s produced in men by the testes. Sometimes in primary hypogonadism testosterone levels are within the normal range and gonadotropins are high. This is because these parts of the brain are responsible for the secretion of hormones which control the proper functioning of the ovaries. “Overall male testosterone decline can be attributed to multiple etiologies. The United States has an aging population with older males exhibiting lower testosterone levels. Abnormal testosterone levels can be caused by various factors, including age, lifestyle, and certain medical conditions. If you feel like your testosterone levels might be too high or too low, talk to your healthcare provider. Hypogonadism – reduced testicular function – generally occurs when the total testosterone is less than 300 ng/dL. However, a healthy level for you depends on your age, lifestyle, and bioavailable testosterone level – the unbound testosterone your body isn’t using for daily functions. Newborn boys have very high testosterone levels, because they need that testosterone in utero to develop as males. From the age of two years until the start of puberty, a boy’s testosterone level is naturally very low. That level spikes again during puberty, causing boys to develop underarm hair, go through growth spurts and develop sexually. It’s natural for testosterone levels to vary depending on your age and overall health. If they’re consistently high or low, you may experience unpleasant symptoms worth discussing with your provider. In female secondary sex characteristics adults, high levels of testosterone may be a sign of polycystic ovary syndrome (PCOS).
