Physiologically, urination involves coordination between the , , and. In infants, some elderly individuals, and those with neurological injury, urination may occur as an involuntary. Brain centers that regulate urination include the , , and the. During erection, these centers block the relaxation of the sphincter muscles, so as to act as a physiological separation of the excretory and reproductive function of the penis, and preventing urine from entering the upper portion of the urethra during ejaculation. Voiding position The distal section of the urethra allows a human male to direct the stream of urine by holding the penis. This flexibility allows the male to choose the posture in which to urinate. In cultures where more than a minimum of clothing is worn, the penis allows the male to urinate while standing without removing much of the clothing. It is customary for some men to urinate in seated or crouched positions. The preferred position may be influenced by cultural or religious beliefs. Research on the medical superiority of either position exists, but the data are. A summarizing the evidence found no superior position for young, healthy males. Erection Main article: An erection is the stiffening and rising of the penis, which occurs during , though it can also happen in non-sexual situations. Spontaneous erections frequently occur during adolescence due to friction with clothing, a full bladder or large intestine, hormone fluctuations, nervousness, and undressing in a nonsexual situation. It is also normal for erections to occur during sleep and upon waking. The primary physiological mechanism that brings about erection is the autonomic of supplying to the penis, which allows more blood to fill the three spongy erectile tissue chambers in the penis, causing it to lengthen and stiffen. The now-engorged erectile tissue presses against and constricts the veins that carry blood away from the penis. More blood enters than leaves the penis until an equilibrium is reached where an equal volume of blood flows into the dilated arteries and out of the constricted veins; a constant erectile size is achieved at this equilibrium. The scrotum will usually tighten during erection. Erection facilitates though it is not essential for various other sexual activities. Erection angle Although many erect penises point upwards see illustration , it is common and normal for the erect penis to point nearly vertically upwards or nearly vertically downwards or even horizontally straight forward, all depending on the tension of the that holds it in position. The following table shows how common various erection angles are for a standing male, out of a sample of 1,564 males aged 20 through 69. In the table, zero degrees is pointing straight up against the abdomen, 90 degrees is horizontal and pointing straight forward, while 180 degrees would be pointing straight down to the feet. An upward pointing angle is most common. Occurrence of erection angles angle ° from vertically upwards Percent of males 0—30 4. A series of muscular contractions delivers semen, containing male known as sperm cells or , from the penis. It is usually the result of , which may include stimulation. Rarely, it is due to prostatic disease. Ejaculation may occur spontaneously during known as a or wet dream. Anejaculation is the condition of being unable to ejaculate. Ejaculation has two phases: emission and ejaculation proper. The emission phase of the ejaculatory reflex is under control of the , while the ejaculatory phase is under control of a at the level of the S2—4 via the. A refractory period succeeds the ejaculation, and sexual stimulation precedes it. The human penis has been argued to have several evolutionary adaptations. The purpose of these adaptations is to maximise reproductive success and minimise. If sperm competition results in the rival male's sperm fertilising the egg, could occur. This is the process whereby males unwittingly invest their resources into offspring of another male and, evolutionarily speaking, should be avoided at all costs The most researched human penis adaptations are testis and , ejaculate adjustment and semen displacement. Testis and penis size Evolution has caused sexually selected adaptations to occur in and testis size in order to maximise and minimise. Sperm competition has caused the human penis to evolve in length and size for sperm retention and displacement. To achieve this, the penis must be of sufficient length to reach any rival sperm and to maximally fill the vagina. In order to ensure that the female retains the male's sperm, the adaptations in length of the human penis have occurred so that the ejaculate is placed close to the female cervix. This is achieved when complete occurs and the penis pushes against the cervix. These adaptations have occurred in order to release and retain sperm to the highest point of the vaginal tract. As a result, this adaptation also leaves the male's sperm less vulnerable to sperm displacement and semen loss. Another reason for this adaptation is due to the nature of the human posture, gravity creates vulnerability for semen loss. Therefore, a long penis, which places the ejaculate deep in the vaginal tract, could reduce the loss of semen. Another evolutionary theory of penis size is female mate choice and its associations with social judgements in modern-day society. A study which illustrates female mate choice as an influence on penis size presented females with life-size, rotatable, computer generated males. These varied in height, body shape and flaccid penis size, with these aspects being examples of masculinity. Female ratings of attractiveness for each male revealed that larger penises were associated with higher attractiveness ratings. These relations between penis size and attractiveness have therefore led to frequently emphasized associations between masculinity and penis size in popular media. This has led to a social bias existing around penis size with larger penises being preferred and having higher social status. This is reflected in the association between believed sexual prowess and male penis size and the social judgement of penis size in relation to 'manhood'. Like the penis, sperm competition has caused the human testicles to evolve in size through. This means that large testicles are an example of a sexually selected adaptation. The human testicles are moderately sized when compared to other animals such as gorillas and chimpanzees, placing somewhere midway. Large testicles are advantageous in sperm competition due to their ability to produce a bigger ejaculation. Research has shown that a positive correlation exists between the number of sperm ejaculated and testis size. Larger testes have also been shown to predict higher sperm quality, including a larger number of motile sperm and higher sperm motility. Research has also demonstrated that evolutionary adaptations of testis size are dependent on the breeding system in which the species resides. Single-male breeding systems—or societies—tend to show smaller testis size than do multi-male breeding systems or EPC societies. Human males live largely in monogamous societies like gorillas, and therefore testis size is smaller in comparison to primates in multi-male breeding systems, such as chimpanzees. The reason for the differentiation in testis size is that in order to succeed reproductively in a multi-male breeding system, males must possess the ability to produce several fully fertilising ejaculations one after another. This, however, is not the case in monogamous societies, where a reduction in fertilising ejaculations has no effect on reproductive success. This is reflected in humans, as the sperm count in ejaculations is decreased if copulation occurs more than 3 to 5 times in a week. Ejaculate adjustment One of the primary ways in which a male's ejaculate has evolved to overcome is through the speed at which it travels. Ejaculates can travel up to 30-60 centimetres at a time which, when combined with its placement at the highest point of the vaginal tract, acts to increase a male's chances that an egg will be fertilised by his sperm as opposed to a potential rival male's sperm , thus maximising his paternal certainty. In addition, males can—and do—adjust their ejaculates in response to sperm competition and according to the likely cost-benefits of mating with a particular female. Research has focused primarily on two fundamental ways in which males go about achieving this: adjusting ejaculate size and adjusting ejaculate quality. Size The number of in any given ejaculate varies from one ejaculate to another. This variation is hypothesised to be a male's attempt to eliminate, if not reduce, his. A male will alter the number of sperm he inseminates into a female according to his perceived level of sperm competition, inseminating a higher number of sperm if he suspects a greater level of competition from other males. In support of ejaculate adjustment, research has shown that a male typically increases the amount he inseminates sperm into his partner after they have been separated for a period of time. This is largely due to the fact that the less time a couple is able to spend together, the chances the female will be inseminated by another male increases, hence greater. Increasing the number of sperm a male inseminates into a female acts to get rid of any rival male's sperm that may be stored within the female, as a result of her potential EPCs during this separation. Through increasing the amount he inseminates his partner following separation, a male increases his chances of paternal certainty. This increase in the number of sperm a male produces in response to sperm competition is not observed for ejaculates. Quality Males also adjust their ejaculates in response to in terms of quality. Research has demonstrated, for example, that simply viewing a sexually explicit image of a female and two males i. Much like increasing the number, increasing the quality of sperm that a male inseminates into a female enhances his paternal certainty when the threat of sperm competition is high. Female phenotypic quality A female's quality is a key determinant of a male's ejaculate investment. Research has shown that males produce larger ejaculates containing better, more motile sperm when mating with a higher quality female. This is largely to reduce a male's , since more attractive females are likely to be approached and subsequently inseminated by more males than are less attractive females. Increasing investment in females with high quality phenotypic traits therefore acts to offset the ejaculate investment of others. In addition, female attractiveness has been shown to be an indicator of reproductive quality, with greater value in higher quality females. It is therefore beneficial for males to increase their ejaculate size and quality when mating with more attractive females, since this is likely to maximise their also. Through assessing a female's phenotypic quality, males can judge whether or not to invest or invest more in a particular female, which will influence their subsequent ejaculate adjustment. Semen displacement The shape of the human penis is thought to have evolved as a result of. Semen displacement is an adaptation of the shape of the penis to draw foreign semen away from the. This means that in the event of a rival male's sperm residing within the of a female, the human penis is able to displace the rival sperm, replacing it with his own. Semen displacement has two main benefits for a male. Firstly, by displacing a rival male's , the risk of the rival sperm fertilising the is reduced, thus minimising the risk of sperm competition. Secondly, the male replaces the rival's sperm with his own, therefore increasing his own chance of fertilising the egg and successfully reproducing with the female. However, males have to ensure they do not displace their own sperm. It is thought that the relatively quick loss of erection after ejaculation, penile hypersensitivity following ejaculation, and the shallower, slower thrusting of the male after ejaculation, prevents this from occurring. The ridge is the part of the human penis thought to have evolved to allow for semen displacement. Research has studied how much is displaced by different shaped, artificial genitals. This research showed that, when combined with thrusting, the coronal ridge of the penis is able to remove the seminal fluid of a rival male from within the female. It does this by forcing the semen under the of the coronal ridge, causing it to collect behind the coronal ridge shaft. When model penises without a coronal ridge were used, less than half the artificial sperm was displaced, compared to penises with a coronal ridge. The presence of a ridge alone, however, is not sufficient for effective semen displacement. It must be combined with adequate thrusting to be successful. It has been shown that the deeper the thrusting, the larger the semen displacement. No semen displacement occurs with shallow thrusting. Some have therefore termed thrusting as a semen displacement behaviour. The behaviours associated with semen displacement, namely thrusting number of thrusts and depth of thrusts , and duration of , have been shown to vary according to whether a male perceives the risk of partner to be high or not. Males and females report greater semen displacement behaviours following allegations of infidelity. In particular, following allegations of infidelity, males and females report deeper and quicker thrusting during sexual intercourse. Circumcision causes the coronal ridge to be more pronounced, and it has been hypothesised that this could enhance semen displacement. This is supported by females' reports of with circumcised males. Females report that their diminish as intercourse with a circumcised male progresses, and that circumcised males thrust more deeply. It has therefore been suggested that the more pronounced coronal ridge, combined with the deeper thrusting, causes the vaginal secretions of the female to be displaced in the same way as rival can be. It can result from fluid trapped in a foreskin left retracted, perhaps following a medical procedure, or accumulation of fluid in the foreskin because of during vigorous sexual activity. Severe cases can be improved by surgical correction. It is usually harmless and self-corrects within a few weeks. Occasionally there is a total loss of sensation and orgasm. The can be damaged by narrow, hard bicycle seats and accidents. This can also occur in the clitoris of females. A popping or cracking sound and pain is normally associated with this event. Emergency medical assistance should be obtained as soon as possible. Prompt medical attention lowers the likelihood of permanent penile curvature. The reduced sensations can lead to injuries for either partner and their absence can make it impossible to have sexual pleasure through stimulation of the penis. Since the problems are caused by permanent nerve damage, preventive treatment through good control of the diabetes is the primary treatment. Some limited recovery may be possible through improved diabetes control. Diabetes is a leading cause, as is natural aging. A variety of treatments exist, most notably including the drugs such as citrate, marketed as Viagra , which work by. Priapism lasting over four hours is a medical emergency. The causative mechanisms are poorly understood but involve complex neurological and vascular factors. Potential complications include , , and. In serious cases the condition may result in , which may result in. However, that is usually only the case if the organ is broke out and injured because of it. The condition has been associated with a variety of drugs including. Contrary to common knowledge, Viagra will not cause it. It tends not to share the common blue tint with a vein however. It is considered a physical condition. It is fairly common and can follow a particularly vigorous sexual activity for men, and tends to go away if given rest and more gentle care, for example by use of lubricants. Some sources state that circumcision can protect against this disease, but this notion remains controversial among medical circles. Hypospadias can also occur by the downward pressure of an indwelling urethral catheter. It is usually corrected by surgery. However, this disorder is extremely rare. This appears to be culturally conditioned and largely limited to Ghana, Sudan, China, Japan, Southeast Asia, and West Africa. Arrests were made in an effort to avoid bloodshed seen in Ghana a decade before, when 12 penis snatchers were beaten to death by mobs. Surgical replacement The first successful penis surgery was done in September 2005 in a military hospital in ,. A man at 44 sustained an injury after an accident and his penis was severed; became difficult as his urethra was partly blocked. A recently brain-dead man, aged 23, was selected for the transplant. Despite of blood vessels and nerves, the , , nerves and the corpora spongiosa were successfully matched. But, on 19 September after two weeks , the surgery was reversed because of a severe problem rejection by the recipient and his wife. In 2009, researchers Chen, Eberli, Yoo and Atala have produced penises and implanted them on rabbits. The animals were able to obtain and , with 10 of 12 rabbits achieving. This study shows that in the future it could be possible to produce artificial penises for replacement surgeries or. In 2015 the world's first successful penis transplant took place in , South Africa in a nine-hour operation performed by surgeons from and. The 21-year-old recipient, who had been sexually active, had lost his penis in a botched circumcision at 18. An Italian nonprofit known as Foregen is working on regrowing the foreskin, with the procedure potentially being partially surgical. In English, these include 'member', '', 'cock', 'prick', 'johnson', 'dork', 'peter', 'pecker', 'putz', 'stick', 'rod', 'thing', 'banana', 'dong', 'schmuck' and 'schlong' and 'todger'. Many of these especially 'dick', 'cock', 'prick', 'dork', 'putz', and 'schmuck' are used as —though sometimes playfully—meaning an unpleasant or unworthy person. Among these, historically, most commonly used euphemism for penis in English literature and society was 'member'. Other than circumcision, genital alterations are almost universally elective and usually for the purpose of aesthetics or increased sensitivity. Piercings of the penis include the , the , the , the , and the. Male to female who undergo , have their penis surgically modified into a. Female to male transsexuals may have a. Other practices that alter the penis are also performed, although they are rare in Western societies without a diagnosed medical condition. Apart from a , perhaps the most radical of these is , in which the urethra is split along the underside of the penis. Subincision originated among , although it is now done by some in the U. Circumcision A labelled dorsal view of a circumcised penis: 1 , 2 , 3 , 4 , 5. The most common form of genital alteration is : removal of part or all of the foreskin for various cultural, religious, and more rarely medical reasons. For infant circumcision, modern devices such as the , , and are available. With all modern devices the same basic procedure is followed. First, the amount of foreskin to be removed is estimated. The foreskin is then opened via the preputial orifice to reveal the underneath and ensured that it is normal. The inner lining of the foreskin preputial epithelium is then separated from its attachment to the glans. The device is then placed this sometimes requires a dorsal slit and remains there until blood flow has stopped. Finally, part, or all, of the foreskin is then removed. Adult circumcisions are often performed without clamps and require 4 to 6 weeks of abstinence from or intercourse after the operation to allow the wound to heal. In some African countries, male circumcision is often performed by non-medical personnel under non-sterile conditions. After hospital circumcision, the foreskin may be used in biomedical research, consumer skin-care products, skin grafts, or -based drugs. In parts of Africa, the foreskin may be dipped in brandy and eaten by the patient, eaten by the circumciser, or fed to animals. According to , after a , the foreskin should be buried. There is controversy surrounding circumcision. In addition, some doctors have expressed concern over the policy and the data that supports it.
