Phillips K, Matheny AP. No other primate species, including the chimpanzee, is known to have such a global post-pubertal increase in skeletal growth velocity. During puberty the pulsatile secretion of GH increases 1. Evolutionary perspective on human growth. Abstract Puberty is a period of development characterized by partially concurrent changes which includes growth acceleration, alteration in body composition and appearance of secondary sex characteristics.

Boxplot of urinary testosterone and cortisol in captive male orangutan subjects according to categorical age of maturation: early flanging before age 14 or late after age
Effect of growth hormone treatment on adult height in peripubertal children with idiopathic short stature: A randomized, double-blind, placebo-controlled trial. In healthy adolescent males and females, bone mass and density at skeletal maturity are inversely related to the timing of puberty.
Which hormone is most likely to be produced in order to decrease plasma calcium levels?
Subject optional. These approaches are expensive and invasive requiring repeated injections , and GnRH analog and AIs therapy may result in potentially adverse effects in children whose puberty is occurring at a physiologically normal time. The mean take-off age in adolescents growing and peak height velocity PHV differ between boys and girls as well as the contribution of pubertal growth to final height FH are summarized in Table 1.
A longitudinal study of normal children showed that overweight and obesity have significant effect on pubertal growth. Early observations from captivity suggested that development was suppressed whenever a dominant flanged male could be seen or heard [7] — [9] , yet results from male pairings are inconsistent.
