The activation of the HPG axis in both males and females during puberty also causes individuals to acquire secondary sex characteristics. This process, known as gonadarche, is preceded by adrenarche, the maturation of the adrenal glands, which contributes to the production of androgens responsible for some pubertal changes. [19]
During prenatal development, infancy, and childhood, GH and IGF-1 levels are low, but progressively increase and reach a peak at puberty, [5] with a 1.5- to 3-fold increase in pulsatile GH secretion and a 3-fold or greater increase in serum IGF-1 levels being capable of occurring at this time. [6]

The endocrine glands that produce the steroid hormones, such as the gonads and adrenal cortex, arise from the mesoderm.
