What is a normal range for testosterone in men?
February 13, 2023

Laboratory defines the normal range of T in men as 8.40 – 28.70 nmol/L [242.27 – 827.77 ng/dL]. In general, the threshold is taken at 300 – 350 ng/dL to be considered testosterone deficient. In other words, it does not mean that an individual only has testosterone deficiency if it their T level is below the lowest limit.

Even in men with T levels within normal range, it does not necessarily mean that the individual does not have low T. This is because it depends on the baseline T of the individual, and each individual will have an optimal range which is unique to them.

Looking only at T levels will overlook patients with normal range, but still have T deficiency, and therefore it is important to take symptoms into consideration.

At Sigma Health, we pride ourselves at properly diagnosing every man who has symptoms suggestive of low T, and customizing a TRT program for optimal results.
