Rodney rang in to ask, "What's in men's and women's nipples that makes them go erect? Erectile tissue has arteries that can carry blood into it, large spaces that can be filled with the trapped blood, and veins that can be blocked to trap the blood inside. In the human, you mainly find erectile tissue in the penis, in the clitoris, and in the nose. In blokes, the penis can do its erection thing in as little as 3 seconds, swelling up to an average length of and-a-half centimetres, and and-a-half centimetres around. But this is nothing compared to the centimetre-long penis of the boar, the 75 centimetres of a stallion, or the 2-and-a-half-metre-long penis of the blue whale.

So, take care of those nipples, guys and other folks assigned male at birth. So, why do men have nipples? Hussain, L. Ancient peoples knew the circulatory system was important to overall health. However, it turns out that breast tissue begins to develop before SRY kicks in, and since nipples in men essentially do no harm, Gould and Lewontin argue, there has simply never been Free voyeur photots good enough reason—evolutionarily speaking—to do away with them. If you do not agree to such placement, do not provide the information. It's hard to quantify how long sex typically lasts — or "should" last — because there are countless ways to have sex. Kelly and team found that Nippes was a significant difference between the average size of male nipples versus that of female nipples.

  • The nipple is a raised region of tissue on the surface of the breast from which, in females, milk leaves the breast through the lactiferous ducts to feed an infant.

The mature human female nipple has several small openings arranged radially around the tip of the nipple lactiferous ducts from which milk is released during lactation. Other small openings in the areola are sebaceous glands , known as Montgomery's glands.

The areolae can range from pink to red to chocolate brown to dark brown or nearly black, but generally tend to be paler among people with lighter skin tones and darker among people with darker skin tones. The size and shape of areolae and nipples are also highly variable, with those of women usually being larger than those of men and prepubescent girls.

The average diameter of male areolae is around Sexually mature women have an average of A function of the specialized dermis of the areola is to protect the regular breast skin from wear, cracking , and irritation. Infants sometimes create trauma to the nipple and areolae by latching-on of the infant.

The size of the areola implies a need to protect a larger area than the nipple due to many factors that are not fully known. Breastfeeding by the baby innervates slowly adapting and rapidly adapting mechanoreceptors that are densely packed around the areolar region.

Paget's disease of the breast is a malignant condition that outwardly may have the appearance of eczema , with skin changes involving the areola and nipple. From Wikipedia, the free encyclopedia.

He was also suspected in the disappearances of two children, eight-year-old Georgia Weckler and year-old Evelyn Hartley.

Frank was right. Her decapitated corpse, which had been gutted like a deer, hung upside down in an outbuilding. A box held her head and her intestines, and nails had been pounded through her ears. To occupy himself, Gein became an avid reader.

His collection of reading materials, however, was decidedly bizarre. His library included articles about cannibalism, headhunting, shrunken heads, and Nazi lampshades made of human skin. It seems that his reading provided him with some grisly home decorating ideas. He kept organs in his refrigerator and appears to have consumed parts of them after cooking them on his stovetop or in his oven.

Some say that he occasionally shared his macabre dinners with acquaintances. Some serial killers are obsessed with the skulls of their victims. Gein used the skulls from his visits to nearby cemeteries as makeshift soup bowls or ashtrays.

He also embedded the heads of forks and spoons in bones to create his cutlery. The only things missing were the eyeballs, which Ed supplied himself when he wore the masks. But his wardrobe also included several other ghastly items of feminine attire , including a belt made of nipples. These included a wastebasket made of human skin, skulls atop bedposts, a collection of noses, a box full of vulvae, and the head of victim Mary Hogan in a bag.

Gein also had a wall hanging made of body parts. There were other items just as hideous. Several of them, like the corset of human flesh, were intended to aid him in his fetish for dressing as a member of the opposite sex. Consequently, to masquerade as a woman, Gein had to improvise.

In addition to his masks, his corset, and his leggings, Gein resorted to the use of a torso vest. Gein sewed the skin of his victims into the grotesque gowns that he donned when he masqueraded as a woman.

The Reason Why Men Have Nipples

The nipple is a raised region of tissue on the surface of the breast from which, in females, milk leaves the breast through the lactiferous ducts to feed an infant. The nipple is surrounded by the areola , which is often a darker color than the surrounding skin. Nipple or teat can also be used to describe the flexible mouthpiece of a baby bottle.

In humans, nipples of both males and females can be stimulated as part of sexual arousal. In many cultures, human female nipples are sexualized , [4] or " In mammals , a nipple also called mammary papilla or teat is a small projection of skin containing the outlets for 15—20 lactiferous ducts arranged cylindrically around the tip.

Marsupials and eutherian mammals typically have an even number of nipples arranged bilaterally, from as few as two to as many as The skin of the nipple is rich in a supply of special nerves that are sensitive to certain stimuli: these are slowly-adapting and rapidly-adapting cutaneous mechanoreceptors.

Mechanoreceptors are identified respectively by Type I slowly-adapting with multiple Merkel corpuscle end-organs and Type II slowly-adapting with single Ruffini corpuscle end-organs , as well as Type I rapidly-adapting with multiple Meissner corpuscle end-organs and Type II rapidly-adapting with single Pacinian corpuscle end-organs. The dominant nerve supply to the nipple comes from the lateral cutaneous branches of fourth intercostal nerve.

It marks the T4 fourth thoracic vertebra dermatome and rests over the approximate level of the diaphragm. The arterial supply to the nipple and breast originates from the anterior intercostal branches of the internal thoracic mammary arteries; lateral thoracic artery; and thoracodorsal arteries.

The venous vessels parallel the arteries. The rest of the drainage leaves the nipple and breast through infroclavicular, pectoral, or parasternal nodes. Since nipples change throughout the life span in men and women, the anatomy of the nipple can change and this change may be expected and considered normal. Why males have nipples has been the subject of scientific research.

The physiological purpose of nipples is to deliver milk to the infant, produced in the female mammary glands during lactation. During breastfeeding, nipple stimulation by an infant will simulate the release of oxytocin from the hypothalamus. Oxytocin is a hormone that increases during pregnancy and acts on the breast to help produce the milk-ejection reflex.

Oxytocin release from the nipple stimulation of the infant causes the uterus to contract even after childbirth. These contractions are necessary to prevent post-partum hemorrhage. When the baby suckles or stimulates the nipple, oxytocin levels rise and small muscles in the breast contract and move the milk through the milk ducts.

The result of nipple stimulation by the newborn helps to move breast milk out through the ducts and to the nipple. A good attachment is when the bottom of the areola the area around the nipple is in the baby's mouth and the nipple is drawn back inside his or her mouth. The nipple is poorly stimulated when the baby latches on too close to the tip of the nipple. This poor attachment can cause sore and cracked nipples and a reluctance of the mother to continue to breastfeed.

If the baby increases nursing time at the nipple, the mammary glands respond to this stimulation by increasing milk production. Nipple pain can be a disincentive for breastfeeding. In some instances an ulcer will form on the nipple. If a nipple appears to be wedge-shaped, white and flattened, this may indicates that the attachment of the infant is not good and there is a potential of developing cracked nipples.

Nipple discharge refers to any fluid that seeps out of the nipple of the breast. Discharge from the nipple does not occur in lactating women. And discharge in non-pregnant women or women who are not breastfeeding may not cause concern.

Men that have discharge from their nipples are not typical. Discharge from the nipples of men or boys may indicate a problem.

Discharge from the nipples can appear without squeezing or may only be noticeable if the nipples are squeezed. One nipple can have discharge while the other does not. The discharge can be clear, green, bloody, brown or straw-colored. The consistency can be thick, thin, sticky or watery. Some cases of nipple discharge will clear on their own without treatment. It is important to find out what is causing it and to get treatment. Here are some reasons for nipple discharge: [23].

Sometimes, babies can have nipple discharge. This is caused by hormones from the mother before birth. It usually goes away in 2 weeks. Cancers such as Paget disease a rare type of cancer involving the skin of the nipple can also cause nipple discharge. Nipple discharge that is not normal is bloody, comes from only one nipple, or comes out on its own without squeezing or touching the nipple. Squeezing the nipple to check for discharge can make it worse. Leaving the nipple alone may make the discharge stop.

Oftentimes a biopsy is performed. A fine needle aspiration FNA biopsy can be fast and least painful. A very thin, hollow needle and slight suction will be used to remove a small sample from under the nipple. Using a local anesthetic to numb the skin may not be necessary since a thin needle is used for the biopsy.

Some men develop a condition known as gynecomastia , in which the breast tissue under the nipple develops and grows. Discharge from the nipple can occur. The nipple may swell in some men possibly due to increased levels of estrogen. Symptoms of breast cancer can often be seen first by changes of the nipple and areola, although not all women have the same symptoms, and some people do not have any signs or symptoms at all. A person may find out they have breast cancer after a routine mammogram.

Warning signs can be: [29] [30]. Changes in the nipple are not necessarily symptoms or signs of breast cancer. Other conditions of the nipple can mimic the signs and symptoms of breast cancer. Some infections are transmitted through the nipple, especially if irritation or injury to the nipple has occurred. In these circumstances, the nipple itself can become infected with Candida that is present in the mouth of the breastfeeding infant.

The infant will transmit the infection to the mother. In some cases the infection can progress to become a full-blown case of mastitis or breast infection. Herpes infection of the nipple can go unnoticed because the lesions are small but usually are quite painful. Herpes in the newborn is a serious and sometimes fatal infection. Other infections can be transmitted through a break of the skin of the nipple and can infect the infant.

This procedure was historically done only prophylactically or with mastectomy for benign disease over fear of increased cancer development in retained areolar ductal tissue.

Recent series suggest that it may be an oncologically sound procedure for tumors not in the subareolar position. The culture tendency to hide the female nipple under clothing has existed in Western culture since the s.

Exposing the entire breast and nipple is a form of protest for some and a crime for others. But nipple exposure of a man was not regulated. A commentator expressed this opinion on the statute by noting: "Ponder the significance of that.

A man walks around bare-chested and the worst that happens is he won't get served in restaurants. But a woman who goes topless is legally in the same boat as if she'd had sex in public. That may seem crazy, but in the U. The legality around the exposure of nipples are inconsistently regulated throughout the US. Some states do not allow the visualization of any part of the breast.

Other jurisdictions prohibit any female chest anatomy by banning anatomical structures that lie below the top of the areola or nipple. Such is the case in West Virginia and Massachusetts. West Virginia's regulation is very specific and is not likely to be misinterpreted, stating: "[The] display of 'any portion of the cleavage of the human female breast exhibited by a dress, blouse, skirt, leotard, bathing suit, or other wearing apparel [is permitted] provided the areola is not exposed, in whole or in part.

Nudity in photos of paintings and sculptures is OK, too". This was incentive for the Twitter campaign FreeTheNipple. Nipples can be sensitive to touch, and nipple stimulation can incite sexual arousal. Some companies and non-profit organisations have used the word nipple or images of nipples to draw attention to their product or cause. The second of the two, tit, was inherited directly from Proto-Germanic, while the first entered English via Old French.
