Testosterone: when is “low” too low?

For any given person, free testosterone is a set fraction of the total testosterone. Testosterone deficiency (TD) happens in any given person when there is insufficient supply of free testosterone to bind to enough of the androgen receptors. This is termed the threshold level. What happens then, is biochemistry; see symptoms →

This threshold level can vary dramatically in different guys. It could be anywhere from 250 – 700. What’s more, is different guys reach this critical low threshold level at different ages, 25-70 years of age.
