Testosterone can also increase or decrease thyroid functions.

Total testosterone, free T, SHBG, E2, LH/FSH, IGF-1, DHEA/DHEA-s, FT3, FT4, TSH, insulin, all are important hormones to be tested for. They all affect one another in complex ways. Testosterone can raise E2, and more E2 can mean less Free T because it can increase SHBG. Insulin is a very important hormone to keep in check too, as it can in the long run be pro-inflammatory, and inflammation is tied to heart disease, cancer, atherosclerosis, as well as Alzheimer's disease (Amyloid plaques)
