An erection happens when the penis fills with blood and gets hard. The penis has 2 main chambers that run along side the top of the penis shaft. This area, the corpora cavernosa, is made up of spongy tissue, veins, arteries, spaces, and smooth muscles that hold in-flowing blood.
Erections happen when more blood flows into the penis and less blood flows out. The erection process is perfectly normal and can happen at any time throughout the day.
Most healthy males get erections during REM (rapid eye movement) sleep (the time of sleep when dreams happen). Also, erections when waking up are a sign of good penis health.
Usually, erections happen during physical arousal or fantasizing, but other things can cause it to occur. Such causes include pressure on the genital area and pressure from the urinary bladder from the need to urinate.
For an erection to happen, some kind of stimulation makes the brain and penile nerves to get excited. They tell the smooth muscles of the corpora cavernosa to let blood in, and stop blood from flowing out. This has the effect of expanding the penis size.
As the penis gets larger in length and girth, it is normal for it to rise at an angle. This angle is usually anywhere from parallel to the floor to pointing almost straight upward.
Sometimes men are stressed out and can't get an erection. This is just the body's way of dealing with stress (or the "fight-or-flight" response). Worrying about a small penis size or having an unattractive partner can make it impossible for a man to keep an erection.
Other things that affect erections are: the amount of sleep a guy gets, how active he is, and in general, age causes changes in hormone levels, like testosterone.
Erection problems
If a man can't keep an erection for 25% of the time, he may have erectile dysfunction, or ED. Treatments for erectile dysfunction can include penile injections, vacuum pumps, surgery, prosthetic devices, Viagra, hormone therapy, counseling, and natural penis exercises.
Some of these methods try to physically help a guy get an erection, while others improve his sex drive so he can perform better.
Methods like injections, prosthetic devices, and vacuum pumps do not require arousal, as they are based on an automatic response.
Other methods like pills and the natural exercises improve the blood flow into the penis, and make erections possible upon sexual arousal. Some pills work each time you take them, while others work for more long lasting benefits.
Regular erections are a natural part of good male sexual health. The ability to get erections decreases with age, but there are things men can do to improve themselves.
Erection problems can be forever cured with modern methods like surgery, counseling, pills, and even exercises.
Exercise Pills: Time in a Bottle?

California Law Melts Arguments of Trans Fat Defenders
Health advocates are cheering California's new ban on the use of
trans fats in restaurant food by 2010 and in retail baked goods by 2011 -- an action that was strongly opposed by the restaurant industry. Their opposition was understandable on one level: Making foods with trans fats is cheaper. But that's where the argument for trans fats really starts and ends. Saving money is the only advantage -- and there are many serious disadvantages..

Erectile dysfunction (ED) affects the lives of many middle-aged men and their partners. The term erectile dysfunction covers a range of disorders, but usually refers to the inability to obtain an adequate erection for satisfactory sexual activity.
Although erectile dysfunction, formerly called impotence, is more common in men older than 65, it can occur at any age. An occasional episode of erectile dysfunction happens to most men and is normal. As men age, it's also normal to experience changes in erectile function. Erections may take longer to develop, may not be as rigid or may require more direct stimulation to be achieved. Men may also notice that orgasms are less intense, the volume of ejaculate is reduced and recovery time increases between erections. Erectile dysfunction may also be a sign of a physical or emotional problem that requires treatment.
Erectile dysfunction was once a taboo subject, but more men are seeking help. Doctors are gaining a better understanding of what causes erectile dysfunction and are finding new and better treatments.
This Website discusses all about erectile dysfunction, physiology of the normal erection and the pathophysiology, and treatment of ED.
What is Erectile Dysfunction?
Erectile dysfunction or impotence is a sexual dysfunction characterized by the inability to develop or maintain an erection of the penis for satisfactory sexual intercourse regardless of the capability of ejaculation. There are various underlying causes, such as diabetes, many of which are medically reversible.
The causes may be physiological or psychological. Psychological impotence can often be helped by almost anything that the patient believes in; there is a very strong placebo effect.
Due to its embarrassing nature and the shame felt by sufferers, the subject was taboo for a long time, and is the subject of many urban legends. Folk remedies have long been advocated, with some being advertised widely since the 1930s. The introduction of perhaps the first pharmacologically effective remedy for impotence, sildenafil (trade name Viagra), in the 1990s caused a wave of public attention, propelled in part by the news-worthiness of stories about it and heavy advertising.
The Latin term impotentia coeundi describes simple inability to insert the penis into the vagina. It is now mostly replaced by more precise terms.
Signs and symptoms:
Erectile dysfunction is characterized by the inability to maintain erection. Normal erections during sleep and in the early morning suggest a psychogenic cause, while loss of these erections may signify underlying disease, often cardiovascular in origin. Other things leading to erectile dysfunction are diabetes mellitus (causing neuropathy) or hypogonadism (decreased testosterone levels due to disease affecting the testicles or the pituitary gland).
Here are some causes of Erectile Dysfunction:
* Arousal: The first step is sexual arousal, which men obtain from the senses of sight, touch, hearing and smell, and from thoughts.
* Nervous system response: The brain communicates the sexual excitation to the body's nervous system, which activates increased blood flow to the penis.
* Blood vessel response:. A relaxing action occurs in the blood vessels that supply the penis, allowing more blood to flow into the shafts that produce the erection.
Physiology of normal erections:
Penile erections involve an integration of complex physiologic processes involving the CNS, peripheral nervous system, and hormonal and vascular systems. Any abnormality involving these systems, whether from medication or disease, has a significant impact on the ability to develop and sustain an erection, ejaculate, and experience orgasm. Tumescence, the vascular filling of the cavernous bodies, relies on neural and hormonal mechanisms operating at various levels of the neural axis. This is unique among visceral functions because it requires central neurological input.
Andersson et al summarized some of the information related to the pathways involved in erectile function. The degree of contraction of corpus cavernosal smooth muscle determines the functional state of the penis. The balance between contraction and relaxation is controlled by central and peripheral factors that involve many transmitters and transmitter systems. At the cellular level, smooth muscle relaxation occurs following the release of acetylcholine from the parasympathetic nerves.
Pathophysiology of erectile dysfunction:
Erectile Dysfunction is essentially a vascular disease. It is often associated with other vascular diseases and conditions such as diabetes, hypertension, and coronary artery disease. Other conditions associated with Erectile Dysfunction include neurologic disorders, endocrinopathies, benign prostatic hyperplasia, and depression. Conditions associated with reduced nerve and endothelium function, such as aging, hypertension, smoking, hypercholesterolemia, and diabetes, alter the balance between contraction and relaxation factors. These conditions cause circulatory and structural changes in penile tissues, resulting in arterial insufficiency and defective smooth muscle relaxation. In some patients, sexual dysfunction may be the presenting symptom of these disorders.
Treatment:
Sildenafil Citrate is the way to treat Erectile Dysfunction. Generic Viagra contains sildenafil citrate and contains same ingredients like branded drug.
