People often show signs of physical arousal—known as nocturnal clitoral tumescence and nocturnal penile tumescence—during the rapid eye movement (REM) stage of sleep, when dreams occur.

The proper term for "morning wood," or night boners, is "nocturnal penile tumescence" (NPT).

Some men may experience nocturnal penile tumescence during non-REM sleep as well, particularly older men.

The morning penile erection—or as it's medically known, "nocturnal penile tumescence," is not only an interesting physiological phenomenon, it can also tell us a lot about sexual function among men.

She's made no secret of her feeling that morning sex improves her mood all day—and for this reason, among others, she has always had my enthusiastic consent to take advantage of my unwitting tumescence before running out into the dawn.

Another interesting finding from the study backed up something that many penis owners and/or users already knew to be true: Even when they are attached to the same person, some erections are more impressive than others and that differences in tumescence could impact measurements to a significant degree.

Ms Roupenian often peers behind the bedroom curtain: at the woman who wants to be punched and kicked by strangers during foreplay; at the couple who are titillated, then fixated, by the idea of their carnal embraces being overheard; at the man who can achieve tumescence only by pretending "that his dick was a knife, and the woman he was fucking was stabbing herself with it".

The penrig is a unit of tumescence, specifically for the tumescence of the human penis. It is defined as the tumescence that will raise 100 grams of penile tissue through one millimetre.. Friday, 15 March 2019 The word is formed from PENis RIGidity.

Clinically, erection is often known as "penile erection", and the state of being erect, and process of erection, are described as "tumescence" or "penile tumescence". The term for the subsiding or cessation of an erection is "detumescence". Colloquially and in slang, erection is known by many informal terms. Commonly encountered English terms include 'stiffy', 'hard-on', 'boner' and 'woody'.

The safety of the procedure was enhanced by the use of fluid infusion, termed tumescence, a concept formulated by Dr. Andrew Klein.

Tumescence is the quality or state of being tumescent or swollen. Tumescence usually refers to the normal engorgement with blood (vascular congestion) of the erectile tissues, marking sexual excitation, and possible readiness for sexual activity. The tumescent sexual organ in men is the penis and in women is the clitoris and other parts of the genitalia like the vestibular bulbs.

Regularly, men who experience erectile dysfunction are given a nocturnal penile tumescence (NPT) test, usually over a three-day period. Such a test detects the presence of an erection occurring during sleep using either: # a small portable computer connected to two bands placed around the shaft of the penis which records penile tumescence, # a band of paper tape with perforations (similar to coil postage stamps) that is fit snugly around the shaft of the penis and will break at the perforations during penile tumescence. The goal of nocturnal penile tumescence testing is to determine whether a man can experience an erection while sleeping after reporting he is unable to experience an erection while awake. If a man does obtain an erection while sleeping, but cannot obtain one while awake, a psychological cause or a medication side effect is usually suspected.

|
These medications are all types of vasodilators and cause tumescence within 10-15 minutes. Common side effects include priapism, bruising, fibrosis, Peyronies, and pain. Priapism is also often treated with intracavernous injections, usually with sympathomimetic vasoconstricting drugs like adrenaline or phenylephrine.

The researchers reported that 24% of the non-homophobic men showed some degree of tumescence in response to the male homosexual video, compared to 54% of the subjects who scored high on the homophobia scale. In addition, 66% of the non- homophobic group showed no significant increases in tumescence after this video, but only 20% of the homophobic men failed to display any arousal. Additionally, when the participants rated their degree of sexual arousal later, the homophobic men significantly underestimated their degree of arousal by the male homosexual video. The results of this study indicate that individuals who score in the homophobic range and admit negative affect toward homosexuality demonstrate significant sexual arousal to male homosexual erotic stimuli.

The final genital response stage recognizes that with both attention and closer proximity, physical reactions result in genital tumescence. Singer also stated that there is an array of other autonomic responses, but acknowledges that the research literature suggests that the genital response is the most reliable and convenient to measure in males.
|
|
If a male has erectile dysfunction (ED) while awake, but has NPT episodes during REM, it would suggest that the ED is from a psychological rather than a physiological cause. In females, erection of the clitoris (nocturnal clitoral tumescence or NCT) causes enlargement, with accompanying vaginal blood flow and transudation (i.e. lubrication).
|
|
Absence of nocturnal erection is commonly used to distinguish between physical and psychological causes of erectile dysfunction and impotence. The state of a penis which is partly, but not fully, erect is sometimes known as semi-erection (clinically: partial tumescence); a penis which is not erect is typically referred to as being flaccid, or soft.

Vaudeville Jazz singers often incorporated sex sounds into the narrative of the lyrics. Even contemporary music such as Prince's "Orgasm" or Marvin Gaye's "You Sure Love to Ball" includes sounds of the female orgasm. Research has shown music to be an auditory sexual stimulant. In one mood induction study, exposure to certain music resulted in significantly greater penile tumescence and subjective sexual arousal for men.

The infiltration of a solution of anaesthesia- and tumescence-inducing drugs can present medical complications such as a fluid overload of the tissues, the inadequate replacement of the infiltrated solution, and the partitioning (separation) of a single infiltration into several pools, which then are removed by suction lipectomy. Moreover, during anaesthesia, maintaining the patient's stable blood pressure can be difficult, which increases the possibility of bleeding, and the possibility that anaesthetic toxicity can occur if excessive doses are administered by infiltration; the symptoms are manifested as central nervous system (CNS) occurrences of drug-induced anxiety, apprehension, restlessness, nervousness, disorientation, confusion, dizziness, blurred vision, tremors, nausea, vomiting, shivering, and seizures; likewise, as manifestations of drowsiness, unconsciousness, respiratory depression, and respiratory arrest. Furthermore, the toxicity symptoms of a tumescence-inducing drug (e.g. epinephrine) might cause such CNS symptoms, for which reason the operative application of a tumescent drug is limited throughout the operation.

After their mid-forties, some men report that they do not always have an erection when they are sexually aroused. Equally, a male erection can occur during sleep (nocturnal penile tumescence) without conscious sexual arousal or due to mechanical stimulation (e.g. rubbing against the bed sheet) alone. A young man — or one with a strong libido — may experience enough sexual arousal for an erection to result from a passing thought, or just the sight of a passerby.

They are marked by strong, lamellar, axial ribs, of which 16 occur upon the first, 14 upon the second and third, and 18 upon the penultimate turn. The intercostal spaces are somewhat wider than the ribs, and strongly impressed. The periphery of the body whorl is marked by a broad, low keel. The base of the shell has a strongly raised tumescence about the umbilical area, the space between which and the peripheral keel appears slightly concave.

Silver foxes exist in seasonally monogamous pairs for the breeding months of December to April, and most matings occur in January and February. Female silver foxes are monestrous (having 1 estrus cycle per year) with estrus lasting 1–6 days and parturition occurring after about 52 days of gestation. During or approaching estrus, the vulva of silver foxes increases in size and tumescence, indicating the sexual readiness or condition of the fox. Female silver foxes generally breed during their first autumn, but a number of factors that contribute to their breeding success.

Chelicerae: the rastellum is as in the female; the inner margin has seven teeth. The cheliceral tumescence is flat, covered with thin setae on its inferior half. The cephalothorax, legs, and palpi are blackish-brown; the abdomen is brown with light-brown spots. The female has a total length of ; a cephalothorax length of and width of ; a cephalic region length of and width of ; fovea width ; an OQ length and width of ; a labium length of and width of ; and a sternum length of and width of .

The arteries dilate causing the corpora cavernosa of the penis (and to a lesser extent the corpus spongiosum) to fill with blood; simultaneously the ischiocavernosus and bulbospongiosus muscles compress the veins of the corpora cavernosa restricting the egress and circulation of this blood. Erection subsides when parasympathetic activity reduces to baseline. As an autonomic nervous system response, an erection may result from a variety of stimuli, including sexual stimulation and sexual arousal, and is therefore not entirely under conscious control. Erections during sleep or upon waking up are known as nocturnal penile tumescence (NPT).
|
|
Erection and protrusion take place gradually, by the increasing tumescence of the erectile vascular tissue in the corpus cavernosum penis. Most stallions achieve erection within 2 minutes of contact with an estrus mare, and mount the estrus mare 5–10 seconds afterward. A bird penis is different in structure from mammal penises, being an erectile expansion of the cloacal wall and being erected by lymph, not blood. The penis of the lake duck can reach about the same length as the animal himself when fully erect, but more commonly is about half the bird's length.

The Postage stamp test is a test used to evaluate nocturnal erections in a workup of male impotence. A length of connected postage stamps connected by perforations that allow easy tearing are secured loosely around the male's flaccid penis just prior to sleeping. If the perforated connections between the individual stamps are torn upon awakening, this is taken as evidence of nocturnal tumescence. However, there is also a chance that the male may shift his position in bed in such a way as to unknowingly tear the perforated connections between the stamps without having achieved a nocturnal erection, thus causing a false positive.

Such an aversion is sometimes extended to an unattributale cognitive process while at other times men's self and own experience. In such a scenario, due to the essentiality of such reflexes for men, some correspondents have posited the feasibility of such a diagnosis if a man has relatively frequent nocturnal penile tumescence since he will probably not notice his erections then. In cultures that discuss the male genitalia as a singular unit, the phenomenon of castration anxiety may overlap with phallophobia from a linguistic standpoint. Although usually referring to ordinary erections, the term has also been used in toxicological and therapeutic contexts.

The methods for reducing the size of the buttocks include the varieties of liposuction, such as lipectomy (with and without ultrasonic enhancement) to reduce excess body fat, and superficial liposculpture, to reshape, refine, and re-establish the natural contour of the body. The usual buttocks-reduction treatment is lipectomy with applied tumescence and anaesthesia, wherein the body fat is harvested by aspiration (suction) through a small-gauge cannula (2–4 mm) that is inserted through a small incision, either to the intergluteal sulcus (the butt-crack), or to the upper area of the gluteus maximus muscle proper.

Overall, the brain exerts less control over breathing; electrical stimulation of respiration-linked brain areas does not influence the lungs, as it does during non-REM sleep and in waking.Parmeggiani (2011), Systemic Homeostasis and Poikilostasis in Sleep, p. 22–27. The fluctuations of heart rate and arterial pressure tend to coincide with PGO waves and rapid eye movements, twitches, or sudden changes in breathing.Parmeggiani (2011), Systemic Homeostasis and Poikilostasis in Sleep, p. 35–37 Erections of the penis (nocturnal penile tumescence or NPT) normally accompany REM sleep in rats and humans.Jouvet (1999), The Paradox of Sleep, pp. 169–173.

This uncertainty has two contrasting outcomes: it may increase the total amount of parental care that their offspring receives, whilst also reducing the possibility that a female's offspring suffers infanticide. For example, it was discovered that male captive ruffled lemurs (Varecia variegata) were less likely to kill infants that they believed themselves to have sired, supporting Hrdy's second proposition. To successfully ensure paternal confusion, Hrdy predicted that ovulation must be randomly distributed across the term where the sexual swelling is of maximum tumescence. This would ensure that males were unable to use the swelling as a signal of female fertility.

An erection (clinically: penile erection or penile tumescence) is a physiological phenomenon in which the penis becomes firm, engorged, and enlarged. Penile erection is the result of a complex interaction of psychological, neural, vascular, and endocrine factors, and is often associated with sexual arousal or sexual attraction, although erections can also be spontaneous. The shape, angle, and direction of an erection varies considerably in humans. Physiologically, erection is triggered by the parasympathetic division of the autonomic nervous system, causing the levels of nitric oxide (a vasodilator) to rise in the trabecular arteries and smooth muscle of the penis.

In many cases, male night monkeys have been observed drinking the urine of their female mate; it is proposed that the pheromones in the urine can indicate the reproductive state of a female and indicate ovulation. This is especially important in night monkeys as they cannot rely on visual cues, such as the presence of a tumescence, to determine female reproductive state. Therefore, olfactory communication in night monkeys is a result of sexual selection; sexually dimorphic trait conferring increased reproductive success. This trait demonstrates sexual dimorphism, as males have larger subcaudal scent glands compare to female counterparts and sex differences have been recorded in the glandular secretions of each gender.

He wanted to know what additional element had to be present for pleasure to be felt.Sharaf 1994, pp. 209–210. Reich was influenced by the work of the Austrian internist Friedrich Kraus, who argued in his paper Allgemeine und Spezielle Pathologie der Person (1926) that the biosystem was a relay-like switch mechanism of electrical charge and discharge. Reich wrote in an essay, "Der Orgasmus als Elektro-physiologische Entladung" ("The Orgasm as an Electrophysiological Discharge", 1934), that the orgasm is just such a bioelectrical discharge and proposed his "orgasm formula": mechanical tension (filling of the organs with fluid; tumescence) → bioelectrical charge → bioelectrical discharge → mechanical relaxation (detumescence).

In a small (n=148) study performed in the United States, using male college students at one university, the mean age expressed as ideal for a wife was found to be 16.87 years old, while 17.76 was the mean ideal age for a brief sexual encounter. However, the study sets up a framework where "taboos against sex with young girls" are purposely diminished, and biased their sample by removing any participant over the age of 30, with a mean participant age of 19.83. In a study of penile tumescence, men were found most aroused by pictures of young adult females.Quinsey, V.L. The Etiology of Anomalous Sexual Preferences in Men.

Self-Portrait is a 1969 film made by the artist Yoko Ono. The film consists of a single 42 minute shot of the semi erect penis of her husband, John Lennon. Ono said in a 1970 interview with the film critic Philip French that "the critics wouldn't touch it". French recalled in a 2009 article for The Observer that the screening for the press was held at a private cinema in Mayfair with Ono and Lennon present, and "Lasting some 40 minutes (it seemed like an eternity), it focused upon the unaided tumescence and detumescence of his member, reaching some sort of climax with a pearl-like drop of semen".

To meet the functional requirements and the aesthetic expectations (body image) of the patient, the plastic surgeon establishes a realistic and feasible surgery plan by which to correct the anatomic contour deficiencies of the gluteal region. The surgeon and the patient determine the location of the surgical-wound scars, and determine the best operative position, to allow the proper exposure of the pertinent anatomy to be corrected. Because the surgical procedure requires the tumescence and anaesthesia of the gluteal-region area to be corrected, the physician and the anaesthesiologist determine the volumes of the anaesthetic and tumescent fluids to be administered to the patient during the procedure, and so avoid the risks of drugs overdose and toxicity.

Communication consists of various sounds and gestures; such as the presentation of the long eyeteeth while grimacing, a clear threatening gesture. Two celebes macaques grooming each other at the Diergaarde Blijdorp in the Rotterdam, Netherlands Juvenile Celebes crested macaque at the Buffalo Zoo in Buffalo, New York The Celebes crested macaque is promiscuous, with both males and females mating multiple times with multiple partners. The receptivity of the females is clearly indicated by an extreme tumescence (swelling) and redness of their buttocks which, in contrast to the black skin color, is particularly noticeable. The gestation time is 174 days, and the birth of the usually single offspring happens in the spring when food is more plentiful.

It is usually performed at night, when most people sleep, though some labs can accommodate shift workers and people with circadian rhythm sleep disorders and do the test at other times of the day. The PSG monitors many body functions, including brain activity (EEG), eye movements (EOG), muscle activity or skeletal muscle activation (EMG), and heart rhythm (ECG), during sleep. After the identification of the sleep disorder sleep apnea in the 1970s, the breathing functions, respiratory airflow, and respiratory effort indicators were added along with peripheral pulse oximetry. Polysomnography no longer includes NPT, Nocturnal Penile Tumescence, for monitoring of erectile dysfunction, as it is reported that all male patients will experience erections during phasic REM sleep, regardless of dream content.

Once the patient is in the operative position, the surgeon begins the liposuction correction by making incisions to the marks of the surgical- correction plan, and then infiltrates (injects) a solution of anaesthesia- and tumescence-inducing drugs, usually a combination of lidocaine and epinephrine. The volume of the anaesthetic-tumescent solution is gradually infiltrated to the pertinent gluteal area, in order to avoid the nerves and the deeper anatomic structures of the gluteus maximus muscle. The particular anatomic features to be contoured determine the types of cannula (gauge, size, grade) used to effect and control the harvesting of excess adipose fat from the patient's body. For a lipoinjection augmentation, the surgeon first dissects and prepares the augmentation-pocket to which will be injected the autologous fat-tissue.

Contour problems of the corrected gluteal region can be prevented with the operational use of small- gauge cannulas (ca. 2.0 mm) specifically for superficial liposuction; and with the application of cross-pattern harvesting of the excess body fat, to avoid removing too much adipose fat tissue, which might disfigure the contour of the patient's fat-donor area. The possible contour problems that might arise from ultrasonic liposuction are skin burns and hypertrophic scarring, which might occur if the fat-donor area skin is not cooled and protected during the fat harvest. To that end, the infusion of a tumescence-inducing solution to the fat-donor area(s) assists in cooling the patient's skin during the ultrasonic lipo-harvesting; likewise, the application of moist towels, a skin protector, and the constant cooling-fluid infiltration of the cannula in an integrated sheath.

In many cases, the diagnosis can be made based on the person's history of symptoms. In other cases, a physical examination and laboratory investigations are done to rule out more serious causes such as hypogonadism or prolactinoma. One of the first steps is to distinguish between physiological and psychological ED. Determining whether involuntary erections are present is important in eliminating the possibility of psychogenic causes for ED. Obtaining full erections occasionally, such as nocturnal penile tumescence when asleep (that is, when the mind and psychological issues, if any, are less present), tends to suggest that the physical structures are functionally working. Similarly, performance with manual stimulation, as well as any performance anxiety or acute situational ED, may indicate a psychogenic component to ED. Another factor leading to ED is diabetes mellitus, a well known cause of neuropathy).

John Curtis Holmes (né Estes; August 8, 1944 – March 13, 1988), better known as John C. Holmes or Johnny Wadd (after the lead character he portrayed in a series of related films), was, at the time he was active, one of the most prolific male adult film actors, with documented credits for at least 573 films. Holmes was best known for his exceptionally large penis, which was heavily promoted as the longest, thickest, hardest, and longest lasting in the adult film industry, with seminal volume second only to fellow adult actor Peter North's. However, no documented measurement of Holmes' actual penis’ length, girth, tumescence, sexual stamina, or ejaculate volume has ever been confirmed. Near the end of his life, Holmes attained notoriety for his reputed involvement in the Wonderland murders of July 1981 and eventually for his death from complications caused by AIDS in March 1988.

Baer (2001), p. 35. This arousal within the body parts is due to conditioned physiological responses in the brain, which do not respond to the subject of the sexual intrusive thought but rather to the fact that a sexual thought is occurring at all and thus engage an automatic response (research indicates that the correlation between what the genitalia regard as "sexually relevant" and what the brain regards as "sexually appealing" only correlates 50% of the time in men and 10% of the time in women).. This means that an arousal response does not necessarily indicate that the person desires what they are thinking about. However, rational thinking processes attempt to explain this reaction and OCD causes people to attribute false meaning and importance to these physiological reactions in an attempt to make sense of them.. Sufferers can also experience heightened anxiety caused by "forbidden" images or simply by discussing the matter which can then also cause physiological arousal, such as sweating, increased heart rate and some degree of tumescence or lubrication. This is often misinterpreted by the sufferer as an indication of desire or intent, when it is in fact not..
