Growth Hormone is a somatotropin, a peptide that stimulates growth,cell reproduction and cell regeneration . It is important in human development. Throughout life, it regulates the fat,muscle,tissue and bone in human body. It enhances the production of insulin like Growth Factors called somatomedins as functional mediators. The levels increase until the onset of puberty. GH levels reduce from middle age onwards. Its synthesis is stimulated by GHRH (Growth Hormone Releasing Hormone) and inhibited by Somatostatin. GNRH is also responsible for the release of FSH and LH hormones.
Interpretation:GNRH levels are low before puberty. As puberty starts, the levels raise. When the testes and ovaries are fully developed GNRH, FSH and LH productions are controlled by the levels of testosterone, estrogen and progesterone.
