For the 2011 Chinese film, see, Differences between male and female puberty, Body shape, fat distribution, and body composition, Visual and other effects of hormonal changes, Genetic influence and environmental factors, Components of the endocrine reproductive system, CS1 maint: multiple names: authors list (, Garn, SM. For much of puberty, nighttime levels of testosterone are higher than daytime. Colborn, T., Dumanoski, D. and Myers, J.P. Our Stolen Future, 1996, Plume: New York. Statistical associations are not necessarily causal, and a variety of covariables and alternative explanations can be imagined. The release of semen, which contains sperm and other fluids, is called ejaculation. In general, girls who enter puberty late experience positive outcomes in adolescence and adulthood, while girls who enter puberty early experience negative outcomes. The month, the day and the time are noted.

Although there is a wide range of normal ages, girls typically begin puberty around ages 10–11 and end puberty around 15–17; boys begin around ages 11–12 and end around 16–17. 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. Before puberty, the larynx of boys and girls is about equally small. [75], Various studies have found direct genetic effects to account for at least 46% of the variation of timing of puberty in well-nourished populations. Conversely, menarche may be slightly later when a girl grows up in a large family with a biological father present. [4] In the 21st century, the average age at which children, especially girls, reach puberty is lower compared to the 19th century, when it was 15 for girls and 16 for boys. The specific genes affecting timing are not yet known. If genetic factors account for half of the variation of pubertal timing, environment factors are clearly important as well. The mucosal surface of the vagina also changes in response to increasing levels of estrogen, becoming thicker and duller pink in color (in contrast to the brighter red of the prepubertal vaginal mucosa). Most of these "effects" are statistical associations revealed by epidemiologic surveys. BPA mimics and interferes with the action of estrogen—an important reproduction and development regulator. Some investigators have attributed the onset of puberty to a resonance of oscillators in the brain. In many populations the amount of variation attributable to nutrition is shrinking. Puberty definition, the period or age at which a person is first capable of sexual reproduction of offspring: in common law, presumed to be 14 years in the male and 12 years in the female. [76] Among the candidates is an androgen receptor gene.[80]. In Norway, girls born in 1840 had their menarche at an average age of 17 years. Gonadal steroidgenesis in girls starts with production of testosterone which is typically quickly converted to estradiol inside the ovaries. For the botanical term, see, "Sexual development" redirects here. The foreskin then gradually becomes retractable. [52][53] Before puberty, uterine body to cervix ratio is 1:1; which increases to 2:1 or 3:1 after completion of pubertal period. At this point in a male's life the testosterone levels slowly rise, and most of the effects are mediated through the androgen receptors by way of conversion dihydrotestosterone in target organs (especially that of the bowels). During puberty, the production of sex hormones causes other physical changes, including breast development in females and deepening of the voice in males. Furthermore, interpretations of the data are politically controversial because of the ease with which this type of research can be used for political advocacy. [13] Estradiol levels rise earlier and reach higher levels in women than in men. Erotic dreams and fantasies Erotic dreams are also related to a person’s physical and emotional development. In Japan the decline happened later and was then more rapid: from 1945 to 1975 in Japan there was a drop of 11 months per decade. Mechanisms of these social effects are unknown, though a variety of physiological processes, including pheromones, have been suggested based on animal research. shoulder width and jaw) is disproportionately greater, resulting in noticeably different male and female skeletal shapes. All content on this website, including dictionary, thesaurus, literature, geography, and other reference data is for informational purposes only. The researchers hypothesized that neurokinin B might play a role in regulating the secretion of kisspeptin, a compound responsible for triggering direct release of GnRH as well as indirect release of LH and FSH. Most of this sex difference in adult heights is attributable to a later onset of the growth spurt and a slower progression to completion, a direct result of the later rise and lower adult male levels of estradiol.[12]. In France, the average in 1840 was 15.3 years. The onset of puberty is associated with high GnRH pulsing, which precedes the rise in sex hormones, LH and FSH.

In the western world, inflammatory bowel disease and tuberculosis have been notorious for such an effect in the last century, while in areas of the underdeveloped world, chronic parasite infections are widespread. This growth is far more prominent in boys, causing the male voice to drop and deepen, sometimes abruptly but rarely "overnight," about one octave, because the longer and thicker vocal folds have a lower fundamental frequency. Testosterone will cause an enlargement of the clitoris and possibly has important effects on the growth and maturation of the vestibular bulbs, corpus cavernosum of the clitoris and urethral sponge. Estradiol also induces at least modest development of breast tissue (gynecomastia) in a large proportion of boys. More extreme degrees of environmental stress, such as wartime refugee status with threat to physical survival, have been found to be associated with delay of maturation, an effect that may be compounded by dietary inadequacy. Rising levels of estradiol and testosterone produce the body changes of female and male puberty. A substantial product of testosterone metabolism in males is estradiol. Regulation of adrenarche and its relationship to maturation of the hypothalamic-gonadal axis is not fully understood, and some evidence suggests it is a parallel but largely independent process coincident with or even preceding central puberty.

This inhibition of the arcuate nucleus is an ongoing active suppression by other areas of the brain. Smaller increases of FSH induce an increase in the aromatase activity of these granulosa cells, which converts most of the testosterone to estradiol for secretion into the circulation. Production of progesterone in the ovaries begins with the development of ovulatory cycles in girls (during the lutheal phase of the cycle), before puberty low levels of progesterone are produced in the adrenal glands of both boys and girls. [20], Outcomes have generally indicated that early onset of puberty in girls can be psychologically damaging. In England, the average in 1840 was 16.5 years. Girls aged between 15 and 19 make up 40% of anorexia nervosa cases.[86]. The usual sequence is: underarm (axillary) hair, perianal hair, upper lip hair, sideburn (preauricular) hair, periareolar hair, and the beard area. If the childhood inhibition of the arcuate nucleus is interrupted prematurely by injury to the brain, it may resume pulsatile gonadotropin release and puberty will begin at an early age. In response to the signals, the gonads produce hormones that stimulate libido and the growth, function, and transformation of the brain, bones, muscle, blood, skin, hair, breasts, and sex organs. Effects of such small size can never be confirmed or refuted for any individual child. [44] Some men do not develop full facial hair for up to 10 years after the completion of puberty.
