Which hormone is the main growth hormone for men?

Estrogen Growth hormone Testosterone DHEA

Correct Answer:

Growth hormone

Explanation:

Growth hormone is the main driver of growth. It’s released by the pituitary gland and acts on tissues directly and indirectly through IGF-1, which is produced mainly in the liver. This IGF-1 signal promotes the growth of bone, muscle, and other tissues, supporting overall linear and body growth. In men, testosterone helps amplify this process by increasing growth hormone secretion and IGF-1 activity, and by supporting muscle and bone development, but the actual growth-promoting signal comes from growth hormone itself. Estrogen affects growth by speeding up the closing of the growth plates, ending longitudinal growth, and DHEA is a weaker precursor with less direct impact on growth.
