Yes. The connection between low testosterone and bone health is well documented in clinical research. Testosterone supports bone remodeling by stimulating bone-building cells and regulating estradiol levels, which is the primary bone-protective hormone in men. When testosterone falls below the clinical threshold, bone density declines over time and fracture risk increases. Men with confirmed hypogonadism have a measurably higher risk of osteopenia and osteoporosis compared to men with normal testosterone levels.
