Until fairly recently, low testosterone in men (I call it "low T") was treated only in patients with severe and obvious T deficiencies, such as men with congenital hormonal conditions that affected their pituitary gland or those who had lost both testicles to trauma, tumors, or infections. However, as the medical community has learned more about the benefits of T therapy for men with less obvious causes of low T (e.g., improved sexual desire and function, energy, and body composition), there has been concomitant interest in how T relates to other medical conditions, including diabetes. It turns out that the relationship between low T and diabetes is quite involved, although the final chapter on the ultimate nature of the relationship is still to be written. Join discussion...
