No matter what the vocational institute tells you, human skin contains three types of sweat (sudoriferous) glands: sebaceous, eccrine and apocrine. This is what they do:\n\nSebaceous Glands: Moisturizing Skin\nThe sebaceous glands -- or "oil glands" -- are located primarily on the scalp, face, chest and back, numbering approximately 3,000 in each square inch of facial skin. Sebaceous glands produce sebum, a natural skin oil which is a complex mixture of fats and waxes. These glands are present at birth, but begin to secrete sebum actively following the onset of puberty. \n\nLocated at the side of hair follicles, these glands secrete sebum through a small duct inside the hair shaft. The sebum locks in the skin's natural moisture and prevents it from drying out. \n\nEccrine Glands: Body Temperature\nThe average human has between two and three million eccrine glands all over the body, but concentrated in the palms, soles and underarms. Exercise, hot weather, fever and emotional stress stimulate eccrine sweating. The colorless and mainly odorless sweat produced by eccrine glands is mostly water, but also contains inorganic chlorides and low levels of fatty acids. Eccrine sweat aids in regulating body cooling and in the removal of some waste products. \n\nApocrine Glands: The Odor Factor\nApocrine glands are located primarily in the underarm and genital regions. There are approximately 2,000 apocrine glands in the average human body. Like sebaceous glands, apocrine glands secrete their contents to the skin surface through hair follicles. \n\nApocrine glands secrete a milky sweat that is rich in organic materials. This secretion, when broken down by bacteria on the surface of the skin, is the chief cause of body odor. This sweat is produced in response primarily to hormonal stimulation and secondarily to emotional stimuli such as fear and pain. Apocrine glands are present from birth, but do not mature and secrete until the onset of puberty. Therefore, body odor is not usually a problem for children, and is rarely a problem for the elderly as the secretions of apocrine glands are reduced with age.

The insect adipokinetic hormones (AKHs) are a large family of peptide hormones that are involved in the mobilization of sugar and lipids from the insect fat body during energy-requiring activities such as flight and locomotion, but that also contribute to hemolymph sugar homeostasis.\nThe X-organ–sinus-gland complex is located in the eyestalk. The X-organ passes its secretions to the sinus gland, which acts as a release centre into the blood. Hormones liberated from the sinus gland have been shown to influence molting, gonad development, water balance, blood glucose, and the expansion and contraction of pigment cells both in the general body and in the retina of the eye. The Y-organs lie in the maxillary segment of decapods and are the source of molting hormones, or ecdysteroids, which promote molting and interact with molt-inhibiting hormones from the X-organ.\n\nThe brain and thoracic nerve centres produce hormones that promote the development of the sex organs. In addition, certain glands attached to the male reproductive ducts control the development of the male reproductive system; their removal from a young male will cause it to develop into a female. The female ovary also acts as an endocrine organ; its endocrine secretions control the development of the female reproductive system. The brood pouch in both amphipods and isopods also develops under the influence of ovarian secretions. A hormonal system controls the beating of the heart. Nerves from the thoracic centres end in fine secretory fibres in the membrane enclosing the space around the heart (pericardium) and secrete substances that typically produce an increase in both frequency and amplitude of the heartbeat.

Good question\n\nThere are glands that produce a sweat-like substance during arousal, but not from urethra.  \n\nThere are also rare instances in which some women have reported a clear subtance that comes out of the urethra during orgasm similar to a male.  Most doctors attribute this to accidental urination.  \n\nMany "sexologists" and other fake science people claim that this is a normal, common thing and is caused by certain glands in the reproductive system, and that all women can achieve it with practice, etc.., but scientificlly, this is pretty much bunk.  \n\nThere is no good thorough scientific studies of the substances expelled or how they are produced, but most doctors think it's just a little accidental pee.

Yes, they exist, in all mammals, including humans.  Interestingly, though, they don't seem to have a very strong effect on sex drive or attraction- Humans have lost most of their ability to smell, and replaced is with visual and social cues for sex (it's obvious when you think about it-visual porn for men is a multi-billion dollar business, and 50% of all books published are Harlequin Romances).  In a major study, it was shown that the only smell that significantly increased men's sex drive was....cinnamon rolls!  Yes, not kidding...

Most of the time, simple cuboidal epithelium is what makes up glands or secretory tissues like what you would find in your tear ducts or sebacious glands (sweat glands).  They are also found surrounding female ovaries and the thyroid gland, not to mention the very important components of the kidneys (nephrons).

The answer is (b) noradrenaline.  The adrenal medulla is the inner portion of the adrenal gland. The adrenal medulla secretes the stress hormones noradrenaline and adrenaline.

Almost all animals use pheromones.  Hippopotamus females release pheromones to let males know when they are ready to mate (estrus).  Dung is the most important form of hippo scent communication, however.  As a hippo defecates, it wags its tail at high speed, sending dung flying everwhere.  Hippo dung has an exceptionally poignant scent, and is a way to mark territory very obviously.

Here's some text from a 2002 study reported in Neuroendrocrinology Letters that indicates male pheremones (at the heart of "body odor") may have a positive attractiveness effect to a majority of women.\n\nPrevious research has revealed that natural and synthetic pheromones can enhance ratings of opposite sex attractiveness. The present study investigated the effects of exposure to male axillary secretions on female ratings of the sexual attractiveness of male stimuli. Thirty-two female undergraduates, half of whom were contraceptive pill users, rated male vignette characters and photographs of male faces on aspects of attractiveness. On two separate study days, corresponding to different phases of their menstrual cycle, stimuli were presented while exposed to male axillary pheromones and under a control condition (no pheromone). The order of testing was balanced with respect to pheromone/control condition and menstrual cycle phase. Pheromone exposure resulted in significantly higher attractiveness ratings of vignette characters and faces. Use of the contraceptive pill or menstrual cycle phase had equivocal effects on some vignette items and neither had any influence on female ratings of male facial attractiveness. The results of this study suggest that exposure to natural male axillary pheromones can significantly enhance female perceptions of various aspects of male attractiveness.\n-----\nThere's no question that overt and extreme body odor is repellent to many (and certainly it can be!) -- especially since we've been trained by countless advertisements to find it so.  \n\nHowever, it's an evolutionary adaptation of some kind, which (certainly in the pre-bath eras) must have operated as a signal of some kind to females: of health, of strength, of non-sickness perhaps.

What is this stuff, anyway?\nEar wax is a sticky liquid secreted by cerumen glands. It isn't really wax in the 'candle wax' sense (paraffin). Skin contains many tiny glands whose sole purpose is to secrete a variety of substances. Sebaceous glands, for example, secrete sebum, which gives skin its greasy quality. Sweat is also produced by microscopic glands. Cerumen glands are found only in the skin of the ear canals.

Pheromone infused colognes and perfumes put people at ease, around you.  \n\nI wear perfume that has pheromones.  People smile more, are friendlier.. it's true.\n\nJust don't mention to people that you're wearing it.  Or that's all they'll think about while talking to you. lol

As always, to understand things that humans have in their anatomies but that\nhave no apparent use [e.g., arm pit hairs] one needs to think about\nevolutionary forebears and look to closely related species for clues. Two\nlevels to the response: the nature of those particular hairs and how they\nserve to help advertize your basic adult [post-pubertal] human condition,\nhowever masked by contemporary perfumes & deodorants. Hair is akin to fur\nbut without the insulative properties, and comes in generally coarse & fine\nvarieties. The particular coarse hairs which develop in the pubic area and\nin the armpits arise at puberty [clue #1]. Hair follicles in these areas\nhave a type of sweat gland associated with them, called an apocrine gland,\nthat begins to function at puberty and is widely associated with\nscent-communication via chemicals known as pheromones [clue #2]. Apocrine\nglands produce an otherwise non-offensive secretion that now appears to be\nhomologous with animal sex-specific scents. Unfortunately its components are\nbroken down by bacteria to form odors associated with dirty locker room\nsmells. The arm pit hairs serve as extended surface from which these\nvolitile chemicals can be more efficiently broadcast. Scientific data\nsupporting the presence & effect of human pheromones have become more\nsubstantial in the last couple of years. Interestingly, perfume companies\nhave recently begun playing up the nature of human pheromones!\n\nDr. Dinsmore

The Bartholin's glands are two glands located slightly below and to the left and right of the opening of the vagina in women. They secrete mucus to provide lubrication, especially when the woman is sexually aroused, thus facilitating sexual activity.

Sexual Pheromones and Sexual Desire\n\n\nImagine an invisible, undetectable force that's powerful enough to override your sense of reason yet draws you to someone with an almost animal passion. These aren't Cupid's mythological arrows, but real shots of human pheromones. Scientists have been researching for years whether or not humans, like other animals, exude these secret scents, with attention focused on a small organ composed of two small pits a few centimeters up the nose. \nBiologists describe pheromones as "smellprints" supposedly as unique to each of us as our fingerprints. Smell is the most primitive of human senses and, unlike sight and touch, travels a direct route to the brain's limbic lobe where it can provoke an emotional reaction that can, quite literally, be a turn-on. \n\nThere's no doubt that pheromones underlie sexual and other types of behavior in animals, but given the complex human psyche, can these invisible lust signals be all you need for love? The scientific verdict is pending, but an increasing body of evidence suggests that the chemistry of sexual attraction and arousal is more nature than nurture and quite beyond our control. Not so far-fetched a notion considering how often we speak — and sing — of sexual chemistry. \n\nLove or lust — the question hasn't stopped the fragrance industry from attempting to cash in on the accumulating knowledge about pheromones by producing synthetic versions of these elusive chemicals. True, the new fragrances aren't billed as aphrodisiacs. Instead, they're advertised as mood-enhancers designed to help you relax and shed your inhibitions. \n\nWhile there's absolutely no proof that they can deliver on any kind of erotic promise, the new pheromone perfumes are selling briskly, even to repeat customers. Which may prove, yet again, that when it comes to aphrodisiacs, nothing trumps the power of suggestion.

I wore that REALM pheromone perfume for a while years ago.  It didn't really seem to be so powerful.  It smelled good but the guys weren't flocking towards me.  \n\nI think pheromones are more for animals.  For us, it is just a marketing ploy.
