Development of pubic hair
Before puberty
PubertyPuberty refers to the process of physical changes by which a child's body becomes an adult body capable of reproduction. Puberty is initiated by hormone signals from the brain to the gonads ...., the genital area of both boys and girls has very fine vellus hair, referred to as Tanner stage
Tanner stageThe Tanner stages are stages of physical Child development in children, adolescents and adults. The stages define physical measurements of development based on external primary sex characteristic and secondary sex characteristics, such as the size of the breasts, genitalia, and development of pubic hair.... 1 hair. As puberty begins, the body produces rising levels of the sex hormones known as androgens, and in response the skin of the genital area begins to produce thicker and rougher, often curlier, hair with a faster growth rate. The onset of pubic hair development is termed pubarche
PubarchePubarche refers to the first appearance of pubic hair in a child. Pubarche is one of the physical changes of puberty but should not be equated with it since it may occur independently of complete puberty..... The change for each hair follicle
Hair follicleA hair follicle is part of the skin that grows hair by packing old Cell s together. Attached to the follicle is a sebaceous gland, a tiny sebum-producing gland found everywhere except on the hands, lips and soles of the feet.... is relatively abrupt, but the extent of skin which grows androgenic hair gradually increases over several years.In males, the first pubic hair appears as a few sparse hairs on the scrotum
ScrotumIn some male mammals the scrotum is a protuberance of skin and muscle containing the testicles. It is an extension of the abdomen, and is located between the penis and anus.... or at the upper base of the penis
PenisThe penis is an external sex organ of certain biologically male organisms, in both vertebrates and invertebrates.The penis is a reproductive organ, technically an intromittent organ, and for Eutheria, additionally serves as the external organ of urination.... (stage 2). Within a year, hairs around the base of the penis are numerous (stage 3). Within 3 to 4 years, hair fills the pubic area (stage 4) and becomes much thicker and darker, and by 5 years extends to the near thighs and upwards on the abdomen toward the umbilicus (stage 5).Other areas of the skin are similarly, though slightly less, sensitive to androgens and androgenic hair typically appears somewhat later. In rough sequence of sensitivity to androgens and appearance of androgenic hair, are the armpits (axillae), perianal area, upper lip, preauricular areas (sideburns), periareolar areas (nipples), middle of the chest, neck under the chin, remainder of chest
Chest hairThe term chest hair is generally used to describe hair that grows on the chest of human males, in the region between the neck and the human abdomen.... and beard
BeardA beard is the hair that grows on a person's chin, cheeks, neck, and the area above the upper lip. Typically, only males going through puberty, or post-pubescent males are able to grow beards.... area, limbs and shoulders, back, and buttocks.Although generally considered part of the process of puberty, pubarche
PubarchePubarche refers to the first appearance of pubic hair in a child. Pubarche is one of the physical changes of puberty but should not be equated with it since it may occur independently of complete puberty.... is distinct and independent of the process of maturation of the gonads that leads to sexual maturation and fertility. Pubic hair can develop from adrenal androgens alone, and can develop even when the ovaries
OvaryThe ovary is an ovum-producing reproductive organ, often found in pairs as part of the vertebrate female reproductive system. Ovaries in females are homology to testicle in males, in that they are both gonads and endocrine glands.... or testes are defective and nonfunctional. See puberty
PubertyPuberty refers to the process of physical changes by which a child's body becomes an adult body capable of reproduction. Puberty is initiated by hormone signals from the brain to the gonads .... for details.There is little if any difference in the capacity of male and female bodies to grow hair in response to androgens. The obvious sex-dimorphic
Sexual dimorphismSexual dimorphism is the systematic difference in form between individuals of different sex in the same species. Examples include color , size, and the presence or absence of parts of the body used in courtship displays or fights, such as ornamental feathers, horns, antlers or tusks.... difference in hair distribution in men and women is primarily a result of differences in the levels of androgen reached as maturity occurs.Pubic hair and axillary (armpit) hair can vary in color considerably from the hair of the scalp. In most people it is darker, although it can also be lighter. In most cases it is most similar in color to the eyebrows of the individual. On some individuals, pubic hair is thick and/or coarse; on others it may be sparse and/or fine. Hair texture varies from tightly curled to entirely straight. Pubic hair patterns can also vary by race and ethnicity.Patterns of pubic hair, known as the escutcheon, vary between the genders. On most women, the pubic patch is triangular and lies over the mons veneris, or mound of Venus. On many men, the pubic patch tapers upwards to a line of hair pointing towards the navel
NavelThe navel is a scar on the abdomen, caused when the umbilical cord is removed from a newborn baby. All Placentalia mammals have a navel. It is fairly conspicuous in humans.... (see abdominal hair
Abdominal hairThe term abdominal hair refers to the hair that grows on the human abdomen of humans and non-human mammals, in the region between the pubic area and the thorax ....), roughly a more upward-pointing triangle. As with axillary (armpit) hair, pubic hair is associated with a concentration of sebaceous gland
Sebaceous glandSebaceous glands are small glands in the skin which secrete an oily matter in the hair follicles to lubricate the skin and hair of animals. In humans, they are found in greatest abundance on the face and scalp, though they are distributed throughout all skin sites except the palms and soles....s in the area.
FunctionVarious theories concerning the function(s) of pubic hair include:
visual indicator of sexual maturity
Sexual maturitySexual maturity is the age or stage when an organism can sexual reproduction. It is sometimes considered synonymous with adulthood, though the two are distinct....
collection of secreted pheromones
