Not necessarily. If you are not on TRT, then higher SHBG gobbles up your testosterone. Then, as your T production lowers with age, you get less (and less) Free T. Even with upgrading of LH in response, you just can't produce any more T. Eventually it falls below the point you can maintain health and happiness Now add in that SHBG normally increases with age. But if you are on TRT, I actually prefer SHBG on the upper end of normal range. Sure, it binds to the T, but I can easily mass action over the top, by increasing the dose. At this point it is important to remember SHBG binds nearly all sex hormones. This includes the class of hormones known collectively as "estrogen". So lower SHBG gives more Free T, but it also leaves more Free Estrogen to do its dirty work. There are some guys who can tolerate very little estrogen for this reason. You can think of SHBG as a buffer to protect us from too much estrogen.
