Evidence suggests that there is an integral interaction between the endogenous...

...A. Albanese; R. Stanhope During puberty, the growth spurt and stage of pubertal maturation are two processes intimately related both being dependent on the combined action of growth hormone (GH) and sex steroids. While it is well established that both GH and sex steroids are required for a pubertal...

Abnormalities of GH secretion have also been implicated in the development of osteoporosis, but the effect of GH treatment on bone mass in such patients is disappointing. Sex steroids have an important role to play in the acquisition of bone mass, and reduced sex steroid...
