Before puberty, the genital area of both boys and girls has very fine vellus hair, referred to as Tanner stage 1 hair. In response to rising levels of androgens as puberty begins, the skin of the genital area begins to produce thicker, often curlier, hair with a faster growth rate. The onset of pubic hair development is termed pubarche. The change for each hair follicle is relatively abrupt, but the extent of skin which grows androgenic hair gradually increases over several years. In most girls, pubic hair first appears along the edges of the labia majora (stage 2), and spreads forward to the mons (stage 3) over the next 2 years. By 3 years into puberty (roughly the time of menarche for most girls), the pubic triangle is densely filled. Within another 2 years pubic hair also grows from the near thighs in most young women, and sometimes a small amount up the line of the abdomen toward the umbilicus. In boys, the first pubic hair appears as a few sparse hairs on the scrotum or at the upper base of the penis (stage 2). Within a year, hairs around the base of the penis are too numerous to count (stage 3), and within 3 to 4 years, hair fills the pubic area (stage 4), 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 and beard area, limbs and shoulders, back, and buttocks. Although generally considered part of the process of puberty, pubarche 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 or testes are defective and nonfunctional. See puberty 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 difference in hair distribution in men and women is primarily a result of differences in the levels of androgen reached as maturity occurs. Variations Patterns of pubic hair vary among people. On some people, pubic hair is thick and/or coarse, while on others it may be sparse and/or fine. 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. On many men, pubic hair color is closest to the color of their beards (before their beards start turning white with age), which again can vary from the color of the hair on top of the head. 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. As with axillary (armpit) hair, pubic hair is associated with a concentration of sebaceous glands in the area. Like other hair, pubic hair may be infested by lice, with a specific category of pubic lice. Function of pubic hair It is believed that the functions of pubic hair include the dissemination of pheromones and protection from the friction of sexual intercourse. Culture Attitudes Varying American attitudes can be inferred from the slang terms names that multiple editors insist upon adding to this article: bush, bushpie, hairpie, furburger, muff, curlies, etc. Francisco Goya, The Nude MajaIn Japanese drawings pubic hair is often omitted for legal reasons (see hentai), as for a long time the display of pubic hair was not legal. The interpretation of the law has since changed. In Islamic societies, removing the pubic hair is a religiously endorsed hygiene practice, ranked along with circumcision, clipping the fingernails, brushing the teeth, etc. Before the twentieth century, fine-art paintings and sculpture in the Western tradition usually depicted women without pubic hair. John Ruskin, the famous author, artist, and art critic, was apparently accustomed to these depictions and unaware of the actual appearance of nude women. On his wedding night, he was allegedly so shocked by his discovery of his wife Effie's pubic hair that he rejected her, and the marriage was legally annulled. Francisco Goya's The Nude Maja was probably the first European painting to show woman's pubic hair, though others had hinted at it. Modification Trimming or completely removing pubic hair has become a custom in many cultures. The methodology of removing hair is called depilation. It is a common practice in the Islamic world for either sex (men usually prefer trimming or shaving, women prefer complete removal by waxing or shaving) and since the 1960s it has become popular to trim or completely remove pubic hair in the Western societies. Different cultures have different shaving habits as well as different reasons for why they modify or remove pubic hair, which include: hygiene, especially during menstruation aesthetic tradition religion sexual practice, such as BDSM cultures or for oral sex Styles, cultures, norms and taboos Among the more popular styles of trimming and styling the pubic area, include the following: Bikini line - trim the sides of the triangle so that pubic hair cannot be seen while wearing swimwear (either gender) Strip - remove hair from both sides of labia majora, leaving a strip (females) sometimes called a "landing strip" Brazilian Waxing - remove all, but a small patch, line or triangle over the clitoris for females, or penis for males Complete removal of all pubic hair (either gender) See also Acomoclitic (a preference for hairless genitals) Many people of both genders are increasingly shaving, waxing, or otherwise removing their pubic hair. The primary reason for this trend is simply aesthetics, but hygiene is also a motivating factor (less body odor results when areas are shaved because if there is no hair shaft, there is nothing for potentially odor-causing bacteria to adhere to). Removal of pubic hair Pubic hair is usually removed or reduced through use of shaving, but oftentimes for more long-term removal, wax or a mechanical device is used to pull the hair out at the root. The trimming or removal of body hair by men is sometimes referred to as manscaping. In Naturism, nudists who remove of all body hair (and pubic hair in particular) are called "smoothies". In the 1990s, a permanent method of hair removal evolved with many opting for more permanent removal of pubic hair. This method involves the use of focused, high power light. This type of depilation falls under two main categories: IPL (intense pulsed light) and laser epilation. IPL uses broad spectrum (white) light, and laser epilation uses a very specific wavelength (color) of light to destroy the hair-producing gland, the follicle. Unlike some temporary methods, light epilation does not cause razor bumps, ingrown hairs or dermatitis. It is still controversial as to which method, IPL or laser, is the most effective. Removal Methods A full list of methods to remove pubic hair includes: Wet Shaving - requires a sharp edged razor and soapy water or gel Electric Shavers - these electric devices cut the hairs very close to the skin using fine moving blades Epilators - these electric devices use rotating coils to pull the hairs out by the roots Laser epilation and IPL (intense pulsed light) Waxing and Sugaring - Some hair salons in France offer what is called "epil¨¦ complet" which is the removal of all pubic hair using hot wax. Hair removal creams and lotions Electrolysis - involves using a current of electricity down the length of the hair to to kill the hair root Hair Growth Inhibitors - these lotions claim to slow the hair growth and even prevent its growth but they have had limited success Tweezers - this is a manual method usually done to remove any remaining hairs after use of the other treatments. Note that: Electrical razors are a little safer and do not shave off skin along with the hair. Shaving can cause skin irritation and hair getting locked under the skin area. Hair re-growth can sometimes be uncomfortable and itchy, although continued removal reduces this effect. Using hair removal creams or lotions in the pubic and chest areas is not advisable, as it may result in serious skin irritations.

More... :P

Pubic hair actually serves several purposes:

* It's primary purpose is to trap pheremones. This emits an odour which sexually attracts and increases arousal in potential mates. Apocrine glands release pheromones, which get trapped in the pubic hair. The combination of these pheromones and decomposing bacteria that gets caught in the hair, combine to define your scent and stimulate the libido of possible partners.

* It signals that a person has entered sexual maturityand is a valid partner. Pubic hair (and underarm hair) also functions as lubrication. Pubic hair in particular protects against the friction generated during intercourse. Under the arms and between the legs, skin on skin contact causes chafing. But the natural oils from hair and the movement of the hair itself prevents direct skin on skin contact.

Pubic hair also indicates a level of sexual maturity to other humans. The growth of pubic hair usually coincides with the arrival of the stage of puberty where reproduction becomes possible.

* In men it can trap air and therefore help regulate the temperature of the testicles, which is obviously important for men.

Some theories suggest that pubic hair is to provide warmth and reduce temperature fluctuations around the genitals. But others discount this theory, indicating that the amount of hair is insufficient to make any significant difference.

And finally, research indicates that humans have just as many hair follicles over their bodies as apes do; the majority of human hair is simply finer and more lightly coloured. It's been said that human body hair is just leftover from the process of evolution, when primitive humans were covered in hair to provide warmth.

Ok, i read the second post, but i am not interested enough in the subject of pubic hair to read the first one as well...

To be honest I didn't- and not planning to- read the first post. It's too long. Maybe Dr.Stein can tell us the exact answer. :lol:

And the answer of your question (I have heard this from a doctor whose field isgynecology) : The organs that have hair on them are protected by the hair. Also hair provides better friction during intercourse.

But, if you ask my personal opinion, I don't like it neither in men nor in women. :)

I think dr. stein answers all your questions about pubic hair. And his second reply was much more understandable than the first one. :)

Thanks for the effort in explaining this things us. More power to you :) :) :)

"Pubes" do not have a purpose - we interpret the function they may have.

Again annoying with no-purpose? :roll: If it didn't have any purpose, we would highly probably develop not to have them :roll:

Evolution is not directed in its current concept. It's a process of random mutation facilitated by natural selection. Whether "pubes" developed specifically, are remnants of generally heavy body hair from evolutionary past, localized heavier body hair associated with groin region, or some other developmental origin - evolution did not identify a purpose in their development any more than mankind was the purpose of creation/initial life on earth.

The crux of "intelligent design", rejected by biology, is exactly that your'e saying. Some person, intellect, or other powerful concept decided we needed pubic hair and pointed evolution in that direction.
