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. 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. 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. An erection occurs when two tubular structures, called the corpora cavernosa , that run the length of the penis, become engorged with venous blood.
This may result from any of various physiological stimuli, also known as sexual stimulation and sexual arousal. The corpus spongiosum is a single tubular structure located just below the corpora cavernosa, which contains the urethra , through which urine and semen pass during urination and ejaculation respectively.
This may also become slightly engorged with blood, but less so than the corpora cavernosa. The scrotum may, but not always, become tightened during erection.
Generally, the foreskin automatically and gradually retracts, exposing the glans , though some men may have to manually retract their foreskin. In the presence of mechanical stimulation, erection is initiated by the parasympathetic division of the autonomic nervous system with minimal input from the central nervous system.
Parasympathetic branches extend from the sacral plexus into the arteries supplying the erectile tissue; upon stimulation, these nerve branches release acetylcholine , which in turn causes release of nitric oxide from endothelial cells in the trabecular arteries.
The ischiocavernosus and bulbospongiosus muscles also compress the veins of the corpora cavernosa, limiting the venous drainage of blood. After ejaculation or cessation of stimulation, erection usually subsides, but the time taken may vary depending on the length and thickness of the penis. The cerebral cortex can initiate erection in the absence of direct mechanical stimulation in response to visual, auditory, olfactory, imagined, or tactile stimuli acting through erectile centers in the lumbar and sacral regions of the spinal cord.
The penis may erect during sleep or be erect on waking up. Such an erection is medically known as nocturnal penile tumescence informally: morning wood or morning glory. Erection is a common indicator of sexual arousal and is required for a male to effect vaginal penetration and sexual intercourse. Erections are common for children and infants, and even occur before birth. An unusual aversion to the erect penis is sometimes referred to as phallophobia.
Spontaneous erection, also known as involuntary, random or unwanted erection, is commonplace and a normal part of male physiology. Socially, such erections can be embarrassing if they happen in public or when undesired. The length of the flaccid penis does not necessarily correspond to the length of the penis when it becomes erect; some smaller flaccid penises grow much longer, while some larger flaccid penises grow comparatively less.
Its size may be increased by surgery,  although penile enlargement is controversial, and a majority of men were "not satisfied" with the results, according to one study. In regards to the average size of a human erect penis, a study of 15, men, and the best research to date on the topic, as the subjects were measured by health professionals, rather than self-measured, has concluded that the average length of an erect human penis is Although many erect penises point upwards, 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 suspensory ligament that holds it in position.
An erect penis can also take on a number of different shapes, ranging from a straight tube to a tube with a curvature up or down or to the left or right. An increase in penile curvature can be caused by Peyronie's disease. This may cause physical and psychological effects for the affected individual, which could include erectile dysfunction or pain during an erection.
Treatments include oral medication such as colchicine or surgery, which is most often reserved as a last resort. The following table shows how common various erection angles are for a standing male.
An upward pointing angle is most common. Erectile dysfunction occurs for a variety of reasons. Ultimately, the cause for erectile dysfunction is that not enough nitric oxide NO is released by the vascular endothelium of the branches of the perineal artery , a branch of the internal pudendal artery.
Erectile dysfunction may occur due to physiological or psychological reasons, most of which are amenable to treatment. Erectile dysfunction, tied closely as it is to cultural notions of potency , success and masculinity , can have devastating psychological consequences including feelings of shame , loss or inadequacy. Around one in ten men experience recurring impotence problems at some point in their lives.
Priapism is a painful condition in which the penis does not return to its flaccid state, despite the absence of both physical and psychological stimulation. Priapism lasting over four hours is a medical emergency. At the time of penetration, the canine penis is not erect, and only able to penetrate the female because it includes a narrow bone called the baculum , a feature of most placental mammals. After the male achieves penetration, he will often hold the female tighter and thrust faster, and it is during this time that the male's penis expands.
Unlike human sexual intercourse, where the male penis commonly becomes erect before entering the female, canine copulation involves the male first penetrating the female, after which swelling of the penis to erection occurs.
An elephant's penis is S-shaped when fully erect and has a Y-shaped orifice. Given the small amount of erectile tissue in a bull's penis , there is little enlargement after erection.
The penis is quite rigid when non-erect, and becomes even more rigid during erection. Protrusion is not affected much by erection, but more by relaxation of the retractor penis muscle and straightening of the sigmoid flexure. A male fossa's penis reaches to between his forelegs when erect. The retractor muscle contracts to retract the penis into the sheath and relaxes to allow the penis to extend from the sheath.
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.
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'.

8 Myths And Beliefs About The Penis, Analyzed By Sex Experts | HuffPost Life
The Man Manual - men's health made easy in print. Together we can change that. Our online community. My boyfriend has had a scar on his penis on the thin bit where the foreskin pulls back and joins with the head. Recently this split and although it healed a bit it tore again when the skin was pushed back during sexual intercourse.
Please can you advise us on whether this is likely to heal as we currently feel unable to do anything for fear of making it worse.
This frenulum often tears and invariably heals very poorly so it tends to break again in the same place. Unfortunately there is a little artery in there which bleeds quite heavily and can be a tad scary. Simply pressing on it with a cloth or thumb will stop the bleeding.
He can have it removed for good with surgery. I am becoming increasingly worried about the appearance of my penis. When I have an erection my foreskin reamains unchanged, it does not come back to reveal my head as I feel it should. Do I have a larger then normal foreskin and can anything be done about it?
I have no problem in pulling my foreskin back but it does not remain there during masturbation or intercourse. Like many things in life there are larger and smaller.
You can have it removed or even modified by surgery but I honestly don't think it is worth the pain or money it cannot be done on the NHS. Far better to grow into to it rather than suffer a tight pullover. For some time now I have had a painful penis around the base of the helmet. I am circumsised and there is no discharge. Also when having an ejaculation I cannot feel the semen passing up through the penis as I used to. When passing sperm or urine it does not feel free flowing but seems to require effort to make it pass out.
I would really need you age and any past history but unfortunately the sensation of ejaculation does tend to decline with years. Being dehydrated will cause this to some extent so take plenty of fluids. So long as there is no discolouration of the semen or difficulty passing water there is unlikely to be anything nasty going on.
Even so, keep an open mind and see your own doctor if you find things getting worse. Ever since puberty, whenever I have a sustained errection for any time exceeding about 3 minutes or so I seem to "leak" some sort of fluid. This can be very embarrassing.
I usually wear two or three layers as not to show spots on my pants but even then it still shows through. What is this and is there anything I can do? The prostate gland just at the base of the bladder secrets the nutrient material to keep sperm alive on their long trip to the uterus. With an erection the prostate is stimulated to produce plenty of this fluid which is slightly milky looking.
Not surprisingly some of this can leak and cause staining. Most importantly you must remember that any sperm sitting around at the time will be washed down and passed out with this leakage so you could make a women pregnant without realising it if you are having unprotected intercourse. It is quite normal and difficult to stop. One way incidentally of getting a semen sample is to stimulate the prostate with a finger massaging it from inside the anus.
Not every mans idea of a good day out. I am a healthy 30 year old man. My wife and I have always enjoyed a very good sex life. About two months ago, during vigorous sex, I bent my erect penis and felt awful pain. I finished without saying anything, but since then I have had a hard time maintaining my erection.
When my wife is on top, I go limp. This is so devastating and I am too embarassed to go to the doctor. We have moved away from home and this would be my first visit to a doctor I do not know.
I can maintain the erection while I am on top, but nothing like I used to be able to do. Also, my penis looks curved when erect now. It does not get nearly as hard as it used to. I am very upset and am not sure what to do. A lot of my sensation is gone, as well. Please answer me by email as soon as you can.
I'd really appreciate it. I'm afraid you may have fractured your penis. This is possible despite there being no bone present. When the penis is fully erect it is liable to 'break' with trauma. There are different levels of this and it depends upon the amount of damage done to the erectile tissue.
You may find that the penis tends to bend to one side, upwards or downwards. This can be treated but you need to see your GP who will refer you to a urologist.
A while ago I went biking. I biked for about 2 hours on a bad saddle. During the trip and afterwards I had a lot of pain in the area between the scrotum and the anus. This was 2. But, my real problem is the following: before this happened I very easily got an erection. Now with difficulties, and the penis is not getting real hard. It also seems as if it is "broken" at the root.
Can you tell me how serious this is and what I should do about it?? Many thanks in advance. You have succumbed to the dreaded blazing saddles syndrome. Fortunately it is usually quite reversible. A bad saddle under constant use can bruise the pudendal nerve which runs just beneath the skin below the crotch. It supplies all the muscles and blood vessels which control the erection and to some degree passing water at the toilet.
Constant bashing of this nerve can cause a paralysis or neuropraxia which can take quite some time to recover. A similar comparison is the dead arm feeling after falling asleep with your arm over a chair arm or trapped under your body while drunk. In most cases it will return to normal service. You need to look very seriously at your saddle and how it is adjusted. I am a circumsized 31 year old male, with an unusual question It comes out and performs normally when aroused. I am wondering if this condition is normal and if it can cause problems down the road?
Coming from Northern Ireland, I can think of quite a few roads down which having a penis, circumcised or otherwise, performing normally could cause problems. You might also be quite glad for a penis which gets itself out of harms way! Being overweight is the commonest cause of the 'disappearing penis' and by simply losing a few kilos it reappears as if by magic.
Most of us men are obsessed with the length of our tackle but we look at it the wrong way. Don't compare yourself to the man in the next urinal as any sideways view gives a much better perspective than looking downwards.
Get a good look in a mirror and get back on the road, stud! After kissing and petting with a young lady two days later I had a sharp pain in my penis lasting for about 20 seconds.
No sex at all had taken place. Another two days after a reddish purple rash appeared under my foreskin. I had a sharp pains to my penis on initial sex. I think the young lady was just coincidence as I had similar sharp pains months before which lasted about one month but with no rash, this went away.
I am not circumcised. I visited the doctor who thought that it could be thrush so I used caneston for many months. This seemed to do no good. I have now had this problem 14 months and now find sex very uncomfortable.
The rash now seems to have calmed down and blends to the colour of my penis. If you look close you can see like little bloodshot veins. I have visited the GUM clinic and a specialist who said it looked OK but unless it's erect it's very hard to see the problem. I just feel now that sex is a chore as I know it will be an uncomfortable experience. I also noticed that at the same time this rash appeared my sperm had started to produce little transparent lumps in it like jelly which was not there before.
The rash sometimes sends my foreskin underneath all red as well which goes after a day. I suffer from no other symptons in this area. I hope you can lead me in the right direction as no one seems to know the answer but I know it's not normal.
