What does sex hormones produce to stimulate osteoblast?

Sex hormones, particularly estrogen and testosterone, promote the production of osteoprotegerin (OPG) and inhibit the production of receptor activator of nuclear factor kappa-B ligand (RANKL). OPG acts to protect osteoblasts and encourage bone formation by preventing the maturation of osteoclasts, which are responsible for bone resorption. Additionally, sex hormones can stimulate the proliferation and activity of osteoblasts directly, enhancing bone density and overall skeletal health. This balance between bone formation and resorption is crucial for maintaining bone strength.
