9. Describe the effect of testosterone on growth, cessation of growth, and protein synthesis.
- Which of these effects does estrogen also exert?
- Testosterone promotes growth by stimulating the secretion of growth hormone and IGF-1.
- Testosterone also induces closure of the epiphyseal plates and thus stops growth. These effects are
- shared by estrogens. Testosterone alone has the added ability to stimulate protein synthesis in
- nonreproductive organs and tissues of the body.
