Testosterone is the primary mammalian androgen and the "original" anabolic steroid. The signal and mechanism releasing the arcuate nucleus from inhibition have been the subject of investigation for decades and remain incompletely understood. This often precedes thelarche and pubarche by one or more years. For boys, the androgen testosterone is the principal sex hormone ; while testosterone is produced, all boys' changes are characterized as virilization. The age at which puberty begins is affected by both genetic factors and by environmental factors such as nutritional state and social circumstances. However, they have based their conclusions on a comparison of data from with data from

In general, girls who enter puberty late experience positive outcomes in adolescence and adulthood while girls who enter puberty early experience negative outcomes. The usual sequence is: If genetic factors account for half of the variation of pubertal timing, environment factors are clearly important as well. The most important of the environmental influences is clearly nutrition, but a number of others have been identified, all which affect timing of female puberty and menarche more clearly than male puberty. Regular washing under the foreskin was found by Krueger and Osborn to reduce the risk of numerous penile disorders, [43] however Birley et al. The major adrenal androgens are dehydroepiandrosterone , androstenedione which are precursors of testosterone , and dehydroepiandrosterone sulfate which is present in large amounts in the blood. This is stage 3 of breast development. The peak of the so-called "strength spurt", the rate of muscle growth, is attained about one year after a male experiences his peak growth rate. Endocrine perspective The endocrine reproductive system becomes functional by the end of the first trimester of fetal life. By another 12 months stage 4 , the breasts are approaching mature size and shape, with areolae and nipples forming a secondary mound. Estradiol together with other ovarian steroids also cause the darker coloration of the areola. Typically estradiol will also cause pronounced growth of the labia minora and to a lesser degree of the labia majora. Another limitation of the social research is that nearly all of it has concerned girls, partly because female puberty requires greater physiologic resources and partly because it involves a unique event menarche that makes survey research into female puberty much simpler than male. In France, the average in was Most of the increasing bulk of testicular tissue is spermatogenic tissue primarily Sertoli and Leydig cells. Rarely, menarche can occur before other signs of puberty in a few girls. In comparison with the effects of genetics, nutrition, and general health, social influences are small, shifting timing by a few months rather than years. Much evidence suggests that for most of the last few centuries, nutritional differences accounted for majority of variation of pubertal timing in different populations, and even among social classes in the same population. Body and facial hair Facial hair of a male. While estradiol promotes growth of the breasts and uterus , it is also the principal hormone driving the pubertal growth spurt and epiphyseal maturation and closure. These experiences lead to lower self-esteem, more depression and poorer body image in these early-maturing girls. The rise in GnRH might also be caused by genetics. The ovaries or testes respond to the rising amounts of LH and FSH by growing and beginning to produce estradiol and testosterone. Male musculature and body shape By the end of puberty, adult men have heavier bones and nearly twice as much skeletal muscle. The main target cells of FSH are the ovarian follicles and the Sertoli cells and spermatogenic tissue of the testes. Leptin levels rise throughout childhood and play a part in allowing the arcuate nucleus to resume operation. A simple description of hormonal puberty is as follows:
