Medication Erectile Disfunction


 It is believed that 25% of cases of ED in some way connected with the intake of medicines. For example, the Massachusetts study on issues of aging men found that the frequency of ED was 28% among patients receiving treatment for diabetes, 39% among cardiac patients, and 15% among men - hypertensives receiving drug therapy. At present we know a large number of drugs that adversely affect the various links in a sexual act. Some of them have an effect on the central mechanisms of erection (antidepressants, antihypertensive medications central action), while others interact with the peripheral components of the arc at the level of the corpora cavernosa (blockers). Clinical signs of drug ED is relatively rapid onset, temporal association with drug intake, negatively affects the various links in a sexual act, and a decrease in severity of illness or its complete disappearance after discontinuation of the drug.
A special place in the pathogenesis of erectile dysfunction occupy such diseases as hypertension and diabetes. The main factor for the development of ED in this case becomes microangiopathy, which leads to a breach of circulation in cavernous bodies. The influx of arterial blood to the penis is carried out on the dorsal and cavernous arteries, originating from the internal pudendal artery. Further relaxation of smooth muscle elements of the cavernous tissue leads to filling of arterial blood lacunae. This, in turn, leads to compression of subtunikalnyh and emissarnyh venules and blocking the outflow of blood from the penis. This phenomenon is known as venookklyuzivny mechanism. Hypoxia, hypercholesterolemia, hyperglycemia leads to phenotypic changes in cavernous tissue - namely, to increase the synthesis and accumulation of collagen with the outcome in the cavernous fibrosis. Cavernous fibrosis is the main link in the pathogenesis of ED. At 48 h after the erection of the cavernous tissue develops, the degree of hypoxia, at which the induction of collagen synthesis in the cavernous tissue. Oxygenation cavernous tissue occurs during erection of the penis. In men with normal sexual function, not even sexually active, 4-8 episodes of spontaneous erections during the night to ensure adequate oxygenation cavernous tissue to prevent the changes leading to fibrosis. In diabetes the existing microcirculatory disorders aggravated by progressive autonomic neuropathy. There is a correlation between ED and coronary artery atherosclerosis. These diseases have common risk factors - hypertension, dyslipidemia, diabetes, smoking, sedentary lifestyle.

Erectile Dysfunction and Impotence in Different Age

Erectile dysfunction (impotence) in different age
Erectile dysfunction is age-appropriate. So at a young age is dominated by psychogenic and functional mechanisms of erectile dysfunction syndrome (compulsive expectations of failure, violation of the regulation of erection due to vascular dystonia), as well as the true venous insufficiency of the penis. In the older age of these reasons almost no one has to consider.
For erectile dysfunction in middle-aged men are more pressing challenges in a violation of the regulation of erection due to diabetes mellitus, metabolic disorders, alcohol and nicotine, contact with radiation, spinal diseases, endothelial dysfunction.
To existing problems in men older than 45 years joined circulatory disorders in atherosclerosis, hypertension, snoring, obesity. Accumulating and summed pathogenic factors lead to an irreversible process - the formation of cavernous fibrosis, most often in the early stages of exerting themselves pathological venous leakage - withhold an erection.
We consider any erectile dysfunction is not as a fait accompli, and as the stage of disease. In the early stages are formed predominantly psychogenic mechanisms, gradually shifting in the direction of functional disorders of regulation of erection. The process ends with persistent organic anatomical changes. This is a typical course. However, there are forms of erectile dysfunction of primarily organic. For example, cavernous fibrosis due to injury of the penis (including chronic), arterial insufficiency of the penis (also traumatic nature), venous outflow due to the presence of a pathological extension of the vessel, Peyronie's disease and some others.

Why Men Should Not Drink Beer?

In any case - the main moderation. This rule applies to what we eat, and even more to what we drink
You talk a lot about the benefits of alcoholic beverages in small doses, but that's the harm of large doses of no one doubts. Moreover, concerns are not only strong liquor: beer, which many mistakenly believe the most innocuous of alcoholic drinks, beats on health as much. And, as scientists say, especially on male.
The fact is that contained in the beer phytoestrogen (separated from the knobs of hops in brewing) inhibits the secretion of the male hormone testosterone. As a result, the strength in the body begins to recruit female hormone estrogen, which, of course, is present in it and in good condition, but should not prevail. Consequences of a hormonal imbalance can be very different. Here are the 5 most serious of them.
1. Cholesterol rises
Scientists from the University Lisestera (UK) examined a group of young people and found that the highest rates of cholesterol were among those who have and estrogen has been raised, and small. Given that the age problem is compounded, in men over 40 even inconspicuous abnormalities may lead to most deplorable consequences. Estrogen increases the production of so-called. "Bad cholesterol", which is responsible for the development of cardiovascular disease and heart attacks, and prevents the formation of a "good", which, in contrast, improves elasticity of blood vessels and prevents heart attacks.
2. Creeping obesity
Beer belly appears not to, "so that more would climb. Estrogen not only promotes the formation of fatty deposits (which is why many women gain weight during hormone replacement therapy), but also causes them to accumulate it around the waist. And that's not all: the fat cells produce a treacherous enzyme, which ... converts the male hormone testosterone to estrogen! That's physiology plays a cruel joke with us, and its consequences - sagging muscles, constant fatigue and problems with libido. Not to mention the increased risk of diabetes and other satellites of obesity.
3. Inflamed prostate
Lack of estrogen in the male body has long been considered one of the prerequisites for prostate cancer. However, it also carries an excess risk of the body. Although the exact mechanism depends not yet been identified, doctors believed that large quantities of estrogen contributes to the prostate and the violation of its work. If the gland grows, it begins to put pressure on the urinary duct and bladder, and this causes the characteristic increased frequency of "impulses" while difficulties with urination.
4. Growth It grows ... bust!
Every second woman dreams easily and painlessly enlarge breasts. Alas, ironically, this method is only a strong half of humanity. Due to the hormonal imbalance man can easily acquire women's bulges, because fat starts to lay where it tells the female hormone estrogen.
5. Weakens heart
Polish researchers found that the combination of heart failure with elevated levels of estrogen, usually means a man early death. On average, people with these symptoms die in 2 times more likely than others suffering from heart disease. Men with high levels of estrogen and more were located in deep vein thrombosis and, consequently, to heart attacks. However, those same doctors say that too low levels of estrogen in the blood leads to the same consequences.

Smoking, Alcohol and Potency.

Most dangers of nicotine. According to studies, tobacco abuse (more than 20 cigarettes a day) in 11% of men leads to a functional sexual disorders. At the same time when smoking cessation potency in most cases, fully restored.
Abstinence from smoking for 3 - 4 hours before the alleged proximity enhances erections.
Due to the fact that in the initial period of alcohol consumption there is a slight increase in libido and increases the duration of coitus, creates a false impression about its positive effect on male potency. However, these symptoms are short term and in the future they will inevitably give way to decrease libido, weakness of erection, and then the serious sexual disorders. Some men even drunk a glass can cause partial or complete absence of erection. Those extremely rare cases where a man, despite the systematic and large consumption of alcohol remains high sexual activity, or in any way contradict what has been said, but merely indicate that initially a strong sexual constitution of the individual.

How to Increase Erection


1. Regular physical activity. The fact that an erection occurs when the increased blood flow to the penis. At this point, the network is filled with empty veins, which runs in the cavernous and spongy bodies. In order to achieve results fast enough every step to pass three kilometers.

2. Beer in moderation. Czech doctors led by Professor Paul Zemekom found that 1 cup of beer a day (not more!) Is a magnificent natural stimulant.
3. Morning. Chronobiology "science of life rhythms of the claims that 8-9 hours in the morning - an ideal time for sexual activity. The organism produces a heavily male hormones, you just reap the benefits of biorhythms.
4. Walking barefoot. At the foot of man is just a few points that are responsible for increased sexuality in general and erectile dysfunction, in particular: at the base of the thumb on the outside of the foot between the heel and little finger and on the arch of the foot. Suffice it to abandon the house slippers on, and things will go smoothly.
5. Proper nutrition. Oysters, sea fish (especially red herring), bergamot, ginger, cinnamon, figs, dates, raw quail egg.
6. Douches. It is best to pour water all the body (seven times alternately cold, hot, seven times), then the same again to put under douches pelvis. This is followed by a good rub oneself with a towel, paying particular attention to the genitals.

What Controls the Erection?



Indeed, some say that the biggest sexual organ is in our heads. It is the brain "in charge" all forms of human sexual sphere: it creates an emotional mood, the need for sexual intercourse, attraction to the opposite sex and provides a reaction, realizing this attraction. In the language of science attraction to the opposite sex called "libido." Against the background of libido erotic pictures in combination with stimulation of the areas causing sexual arousal center in the brain. As a result, nerve impulses are rushing from the center to the various organs and cause heart "flutter", and breathing - more frequent. Blood pressure rises. Under the "leadership" centers of the spinal cord penis fills with blood, repeatedly (4-10 times) increases and strains. So there is an erection. Emotional arousal and activation of the glans penis lead to a reduction in seminal vesicles and release of sperm - ejaculation and orgasm. Violation of any of the coordinated work of these links may cause sexual disorders, primarily the loss of the capacity for erection. From ancient times was the search for means that would help the man. He drank a love potion, or better yet unobtrusive swallowed a pill - and please, appeared before a woman in full force and readiness. Such tools called "afrodiziakum" on behalf of Aphrodite, the Greek goddess of sensual love. Despite the centuries-old quest, the vast majority of these funds were either tonic like ginseng and vitamins, or exciting, like coffee and chocolate, or just mascots, acting purely psychological. The only effective means was the bark of the African yohimbe tree. Why is it so hard to influence the behavior of the penis? After all, people are usually well managed by his body: even with his eyes closed and in weightlessness his hands and feet in full are subject to the will. But the thing is that we are able to command only those muscles which are attached to bones. But there are other muscles that are not subject to us. They are located in the walls of internal organs and blood vessels. The penis is under the control of these muscles, and therefore almost independent of the will of the owner. Nevertheless, its behavior is determined by nerve impulses. Nervous system of regulation reminds telegraphy. At the command post there is an "order" in the form of electrical signals that run through the wires - the nerves. At the end of the wire sits "telegraph," sending the pulses in the order, which serve the public. These orders and there are those substances that cause the muscle is reduced, then relax.
Inside the penis are two so-called cavernous body. Along the walls of the "caves" are the muscles through which they can change their volume. In the usual, "sluggish" state of the muscles of cavernous bodies and muscles of small arteries of the penis in a state of weak reductions - tone. They constantly circulates a small amount of blood, but to give the elasticity of the penis is not enough. The situation is completely changed when sexual excitement. By genitals received powerful impulses that cause relaxation of muscle fibers in the walls of arteries and corpus cavernosum penis. As a result, the penis and erectile tissues fill with arterial blood, increasing in size - there is an erection. When sexual arousal decreases, the muscles in the cavernous bodies are reduced and squeezed out their blood like water from a sponge - there comes an end to an erection. Substance which gives the order to relax the muscles, called acetylcholine. It is rapidly destroyed special enzyme. When rats were injected substances, suspending the operation of this enzyme, they copulate for hours. However, these substances act indiscriminately. American scientists have proposed another solution to this problem. In 1998 he was awarded the Nobel Prize in Medicine for his discovery of special chemical link between acetylcholine and muscle. This nitric oxide, which ensures the formation of substances that lead to relaxation of the muscles of the corpora cavernosa and the erection. Now, pharmacologists were able to manage this process.
At what age erections appears and disappears when the norm?
The first physiological erection occur in boys as early as 5-6 years and are not affiliated with erotic feelings. Then erection become more frequent, and during puberty, they are already there as a sign of attraction to the opposite sex. Maximum capacity for erection in men about 20 years old, then it gradually decreases, but completely disappears each in its time - someone is saved up to 90 years old, someone lost and after 40 years.
What diseases lead to the loss of capacity for erection?
First alcoholism, because in large doses alcohol acts detrimental to the ability to erect. The same thing - drugs, especially cocaine, ecstasy, fenamin: they are for a short time increase the potency, but just a few tricks "turning off" her. Reduces the potency and prostate, and diabetes, and some hormonal diseases, as well as sclerosis of the vessels, especially vessels of the lower extremities. The same happens if, without the doctor's advice begin taking male sex hormones - their excess acts exactly the opposite way. Bad affects depression, anxiety, waiting for some kind of trouble.
When there is a breakdown of erection?
In young people's erection during first sexual intercourse is often disrupted due to excessive excitation. The more the young person wants to close, the harder erection occurs. And here it is important to conduct discreet women - for some reason in itself, in that it is something not said or done. If something does not work after repeated contacts - can be suspected pathology. In general, individual women is not so much to men in 20 years, but the older he gets, the more important it becomes for her individuality.
How does an erection on the intensity of sexual activity?
Bad affects any deviation from the norm - as the excess and deficiency. It is known that long periods - several months - reduce erections. There is even a concept such as "impotence of seafarers. On the other hand, 7-8 sex acts a week, too, can reduce the potency.
What may be considered normal sexual life?
Everyone, of course, it is ours. But the average family man is 2.3 sexual intercourse per week. Minimum normal frequency - once every two weeks.
Is the ability to conceive with erection?
Not directly. The man making the peak of sex hormones is achieved by 30 years, and the potency of this time is reduced, albeit very slowly. The ability to conceive remains much longer. Although, if infertility due to lack of sex hormones may be impaired and erection.
How does physical activity?
Moderate exercise increases the potency, excessive - decreases. The fault is not only fatigue. Building strong muscles "takes" a lot of sex hormones, resulting in reduced potency. This is to remember those who are keen on bodybuilding.
Does the capacity for erection of nationality?
It is known that Southerners easily and quickly excited, but can not long retain an erection. Northerners - the opposite.

Medical Treatment of Erectile Dysfunction

Most doctors choose an aggressive approach to treatment of erectile dysfunction. But for some need only a few steps toward a healthy lifestyle. For example, Quit smoking, get rid of excess weight, increase physical activity and, in some cases, this will help you to restore sexual function. The next step towards getting rid of erectile dysfunction can be cut in receiving medical drugs and medicines. Every medication has side effects, even if they are not visible. If you believe that what the drug is harmful to your health, then tell your doctor. He always tells what medication can replace your. Such techniques as psychotherapy and behavior change are acceptable for some patients, only in rare cases when medical products, implants or vacuum devices have already done their job. In very rare cases, surgical intervention is appointed.
Now consider these methods in more detail.

Psychotherapy
Experts often refer to this method for the treatment of erectile dysfunction, based on psychological factors, using methods that root of the anxiety associated with intercourse. In this case, the patient's partner can help with methods that involve a gradual increase of excitation in an intimate atmosphere. Such methods may also help ease anxiety during the treatment of physical causes of erectile dysfunction.

Drug therapy

Variety of drugs for the treatment of erectile dysfunction is striking. They can be used orally, injected directly into the penis or inserted into the urethra at the tip of the penis. As mentioned in previous posts, and March 1998, the Ministry of Health has approved medication for the treatment of erectile dysfunction, Viagra. A year later, were approved vardenafil hydrochloride - Levitra and tadalafil - Cialis. These drugs have become the first pill to treat erectile dysfunction. All of these drugs Viagra, Levitra and Cialis belongs to a group of phosphodiesterase inhibitors. Accepted for 30-45 minutes before sexual activity, these drugs relax the smooth muscles of the penis during sexual stimulation, allowing increased blood flow.

What Determines the Potency?

After research, American scientists have concluded that most men rarely sexually active potency of no less than those who live twice as often. The rarity of the relations they have depended on various factors, not allowing to demonstrate its potency in full. On what does the potency of why one "lucky" while others consider themselves to be disadvantaged?


On the one hand, some men's power lays in the body of nature. Just as there are people more powerful or fast, durable and sharp-sighted, and the potency of each person initially depends on the physical data.

However, as it will show the man himself - the whole force of his stock, or half, depends on the conditions in which he grew up and is talking to whom. Of course, to rise above its natural limit can not be nobody, but physically strong, healthy men are more likely to perform well in bed at any age. Poor health, alcohol, drugs, excessive smoking, obesity - all this does not lead to manifest even the nature of good potency.

Unfortunately, men often are not inclined to pay attention to their health, yet the process does not go far and do not require serious medical intervention. But the negative effect on the potency of almost any disease, and not only related to the reproductive system - the kidneys, reproductive organs, prostate gland, the endocrine system. For any ailment makes a person focus on the pain, think about the possible complications, and not about pleasures.

Of course, if a person with something sick for many years, there's nothing to be done. But with some perseverance we ourselves are undermining your health! Alcohol and smoking escorted us to the youth and did not improve health, and hence potency. Reluctance to go to the doctors too difficult to follow-up treatment. Occupational hazard in the workplace - in general scourge of many modern men.

In the list of candidates for the reduction of potency in the first place, perhaps you can put motorists and drivers. Constant shaking on rough road leads to poor circulation in the genital organs, long-term inflammation of the prostate, and then decrease of erection and desire. There are simple ways to reduce shaking when driving a car, but neglected. In addition, despite numerous warnings, the drivers very close contact with gasoline. Even if there is no apparent poisoning of the body, falling gasoline vapor in the blood dramatically reduces the ability of male sex.

High risk of winter fishing enthusiasts, sitting on the ice, "walruses", workers of hot shops, miners, sailors, and many others. Practically, every man, hoping to public concern, we should look around at work and determine what can threaten their health in general and in particular potency. Adverse effect on the potency of overweight, which has a lot of men. The fact that the adipose tissue as it burns the hormones, and obesity makes the increased load on the heart, blood vessels, muscles, making it difficult to close, and gradually develops to her reserved attitude.

Therefore, a man striving to improve the potency should watch their weight, if necessary, to comply with diet or fasting days. After all, if many of the disease arise independently of us, obesity - entirely within our control and we can get rid of him!

One of the worst enemies of potency - alcohol. Ancient doctors said: "The wine excites a desire, but makes it impossible to implement them. Alcohol clouds the brains, reveal excitement but also a detrimental effect on the centers of the spinal cord that control erection and ejaculation. Some men take to the proximity of a glass "for relaxation". Yes, it is known that small doses of alcohol relieve stress, a reminder of the insecurity, of a bad relationship with his wife, of insecurity in life. Therefore, it may turn out better than usual.

But every time "to take on a glass" - a direct path to alcoholism. The only correct way - to change the relationship with his wife, make her an ally in bed, than every time an artificially spur itself. Situation is even worse for men who use drugs. In terms of sex no drugs weak or strong, they are only negative. Even those who in some cultures are traditional, even among adolescents (marijuana, hashish), quickly lead to severe and often irreversible loss of potency.

Drugs are ruining not only the will, but also the body, even worse acting on the sexual centers than alcohol. Tale of the fact that drugs exacerbate sexuality, in fact, limited to self-deception, illusion of solving all problems.

Enormous role in the manifestation of male potency are psychological factors. Even in his youth, when passion burns just a man inside, when he seems ready for intercourse at any time, cold and inept woman can not allow him to manifest itself fully. In the intima of marriage - its peculiarities. Agree that all the marital problems are solved in bed - just a fairy tale. In fact, a bad relationship with his wife is not able to fully relax and properly stirred. Offended woman will not help your partner, and, possibly, do anything to hinder his normal intimacy.

Therefore, the right must have been wise ancient Chinese speaking, the main thing - to satisfy a woman. And is it possible that, if you do not love her, but she does not love you? Moreover, this disparity is evident with age, and even more - if a permanent partner, the wife is unopened, constantly squeezed outwardly non-sexual woman. At other times, not allowing her husband to show himself a real man, she also blames him for men's weakness, although the reason for this "weakness" - herself. Yes, it happens. But there are also counter-question - why the man was unable (or unwilling) to awaken her as a woman, which it would be expensive, not only as head of the family and the father of the children, but also as a man ...

Fully cooled to its "half" often ends with the invisible world, but lasts for years, family battle. So the couple shared household duties, the love of children, the friendship with buddies or girlfriends. But all such conflicts weaken the internal relations of the spouses, reduce the value of intimacy, but at the same time - and the potency of men. Our education leads to the fact that the man often lies in bed worried their own problems - conflict at work, trouble with her son, lack of money.

ty habitual thoughts are not allow to devote ourselves entirely to his initiation, and therefore does not develop a normal erection. If this condition is repeated over and over again, the man's fear does not appear to meet the expectations of his wife and a vicious circle: I'm afraid I can not, and therefore not to proceed, and if not excited, then fails. Repetition of such on anything not specifically based missteps, the pangs of his wife, his own experiences - all this leads to neurosis expectations of failure, which is the reason for the reduction of potency in up to 40% of men seeking to sexologist.

This neurosis is that the man with the desire to bring pleasure to a woman instinctively switches to himself. He is waiting with trepidation as to whether he had an erection, which she followed, much whether he is excited, etc. It turns out that instead of rest and pleasure, double bed brings him only suspicion and frustration. Of course, the potency of his falls.

Finally, the reason for the reduction of potency can be hard work, too active lifestyles who simply do not leave the forces for sex. It is clear that in addition to these factors, to affect the potency and many others, specific to each case. For example, in our country are still frequent complaints men to reduce the potency for one simple reason - they simply have nowhere to live sex. It is not uncommon for a single room living husband and wife, two children and mother-in-law.

Thus, we can say that the manifestation of potency depends on the innate strength, men's health, alcohol or drug use, relationships with close friend. And, basically, potency - is a manifestation of general health. Clearly, in terms of malnutrition and a nasty environment, even men with good natural instincts will not be able to show the potency, as though living in more favorable conditions, write bayki.

Unfortunately, until now, most men measure their potency on a purely physical characteristics - the size of genitals, frequency or duration of intercourse, the speed of erection. This is wrong, potency may be easier to determine how to satisfy a woman. In other words, the potency of a man appreciates a woman. Often, one man lives with two women and one of his crazy, while the other considers full impotent. Why? Obviously, everything depends on the amazing and mysterious feeling of love, which inspire any words and deeds.

So:

1. First, you need to feel the anal sphincter and learn how to draw it deeper. Initially it was felt more or less compression of the anus - it retracted upward. In order to get a better feel retracted anus to examine the action manually.

2. In the squatting position lubricated finger is introduced into the anus (approximately two phalanges). Or you can simply substitute the fingertip to the anus without the introduction.

3. To learn more simply compress the finger.

4. With compression, the anus is drawn up. Understand what muscles are made, learn to draw more ass up.

Erectile Dysfunction: Cialis, Viagra and Levitra to Treat Erectile Dysfunction

There are three the most effective oral drugs approved by the FDA to treat erectile dysfunction: Cialis, Levitra, and Viagra. All the drugs work by increasing the flow of blood into the penis so that when a man is sexually stimulated, he can get an erection.

What Are the Differences Between Cialis, Levitra, and Viagra?

Cialis, Levitra, and Viagra work by a similar mechanism to cause erections. There are subtle differences in how long the drug works and how quickly it works. Levitra works a little longer than Viagra. They both take effect in about 30 minutes. With Levitra, the effects last for about 5 hours. With Viagra, the effects last approximately 4 hours.

Cialis works a little bit faster, within about 15 minutes, and the effects last much longer - up to 36 hours in some cases.

If One of These Drugs Isn't Effective for Erectile Dysfunction, Can It Be Substituted By Another?

Yes, but because these drugs work the same way, it's unlikely that you'll have success with one if you've failed to achieve an adequate erection with another.

Precautions Before Taking One of These Drugs?

There are certain situations in which these drugs may not be safe to take. Before taking them, tell your doctor:

    * If you are allergic to any drugs, including Viagra or other ED medications.
    * About any prescription or nonprescription medications you are currently taking, including herbal and dietary supplements.
    * If you are scheduled for surgery, including dental surgery.
    * If you take nitroglycerin or a long-acting nitrate to treat chest pain. The combination of Cialis, Levitra or Viagra with these drugs can cause dangerously low blood pressure.
    * If you take alpha-blockers for blood pressure or prostate problems. The combination of Cialis or Levitra with these drugs can also cause dangerously low blood pressure.

In addition, always follow the directions on your prescription label carefully and ask your doctor or pharmacist to explain any part that you do not understand. Take these drugs exactly as directed. Do not take more or less or take it more often than prescribed by your doctor. Do not take these drugs more than once a day.
