Low Testosterone?

Started experiencing severe fatigue about 2 months ago; transplant doc finally tested testosterone last week. My total testosterone came back mid-range of normal (536), but my SHBG is very high (110), which is binding up most of it. Because of that, my free testosterone is actually low (43), less than half of the bottom range of normal, so effectively have very low usable testosterone despite a normal total level. Has anyone post-transplant dealt with high SHBG and low free testosterone causing severe fatigue? My team is going to have me see an endocrinologist.
