Low Testosterone, or hypogonadism, refers to a decrease in testosterone levels either due to a problem with testicular production or problems in the pituitary gland in your brain. Levels of testosterone are typically measured under 300ng/dl and lead to unwanted symptoms.
Some men, even with testosterone levels over 300 will be labeled “low-normal”. For example, a 35-year-old man with a testosterone level of 340 falls in the normal range according to lab reports (250-1000 ng/dl), but for his age he suffers from low T if he is experiencing low T symptoms.
Men experiencing symptoms with “low-normal” testosterone levels often benefit greatly from getting to a more optimized range over 800ng/dl.
