The Definition of Erectile Dysfunction
Erectile dysfunction (ED), also called impotence, is persistent inability of a man to have or maintain a penile erection during sexual intercourse with his sexual partner (at least in 25% of intercourses). Troubles with erection may happen from time to time, which is normal and not a reason for concern. But if this problem takes place systematically, the man should pay attention to his health. Erectile dysfunction is a common problem among men - approximately around one third of all men aged between 40 and 70 experience some degree of erectile dysfunction, both occasionally and regularly. In medicine ED is covered by urology’s sub-field – andrology.
Erection of the penis occurs when blood enters sponge-like bodies of the penis and is being retained there. It is caused by sexual arousal, which is a result of signals transmission to the penis nerves from the brain. So, anything that impairs blood flow in the penis or causes injury to the nerves is potentially able to cause ED.
What Causes Troubles with Erection?
It is important not to panic and to understand that ongoing troubles with erection are not necessarily the consequence of disease. There is such term as psychological impotence, which means failure of erection or penetration due to psychological reasons – feelings or thoughts, for example when a man is afraid that he is not that good for his sexual partner. Another reason may be systematic stress and chronic fatigue, depression, hypertension, unresolved sexual orientation, conflicts with the sexual partner, sexual boredom. Erectile dysfunction, in its turn, may negatively affect a man’s confidence, his self-image, cause stress, relationship problems. In psychological cases placebo treatment shows good response.
Organic causes of ED can be the following: hormonal insufficiencies (for example, hypogonadism), neurological problems or traumas, diabetes, cardiovascular diseases, or drug side effects. ED can also be caused by kidney failure, aging, cavernosal disorders, neurogenic disorders, spinal cord injury, surgical intervention, drugs (as anti-depressants) consumption. Smoking is a wide spread cause of impotence, because nicotine promotes arterial narrowing and deterioration of penile blood circulation.
Generally impotence is related to poor health, obesity, poor nutrition, unhealthy dietary habits. By the way, the men who ride the bicycle too often are vulnerable to increased risk of temporary erectile dysfunction, though cyclists in general are healthier than the men avoiding sport. The special saddles can make the risk lower.
Diagnosis: How Do You Know Your Erection Needs Help?
Diagnosing erectile dysfunction can be in some way difficult, because there aren’t any formal tests. First of all, it is important to exclude underlying diseases as prolactinoma or hypogonadism, and for this purpose blood tests are done.
During the first visit the physician usually offers the patient to complete a questionnaire with a set of specific questions that indicate many causes of ED. According to the answers, the physician determines whether the patient has severe, moderate or mild erectile dysfunction, and what its underlying cause is.
A man should pass a thorough physical examination, which can reveal problems that may cause erection problems, such as undetected groin hernia. Based on this information appropriate treatment options can be offered.
The doctor also has to find out whether his patient has psychological or physiological impotence. If a man has full penile erection at some times, for example, when asleep, it means his problem is not physical and functionally everything is ok. If the patient never has erection, the problem is probably physiological.
The following tests can help to get more information about the problem:
- Bulbocavernosus reflex test and other penile nerves function tests are used to find out whether nerve sensation in the penis is sufficient. The head of the penis is squeezed by the physician, and if the nerve function is ok, the anus immediately contracts. To measure it, the physician inserts a gloved finder in the anus.
- Duplex ultrasound is used to evaluate signs of atherosclerosis, venous leak, blood flow, calcification or scarring of erectile tissue. To induce erection, a hormone-like stimulator prostaglandin is injected, and then ultrasound helps to measure penile blood pressure and see vascular dilation.
- Penile biothesiometry test evaluates sensitivity, as well nerve function in the shaft and glans of the penis.
- Nocturnal penile tumescence test (NPT) measures changes in penile circumference and rigidity during nocturnal erection. During sleep and rapid eye movement a man may have 5-6 erections, if he doesn’t it can indicate trouble with penis blood supply or nerve function, though not necessarily.
- Corpus cavernosometry (cavernosography) is made to measure the vascular pressure in the corpus cavernosum. For this purpose saline is infused into the corpus cavernosum, and the venous leakage degree is indicated the flow rate necessary for maintaining erection.
- Magnetic resonance angiography (MRA) allows to see the blood vessels on detailed images that are made using radio waves and magnetic fields. Better visibility can be reached by injecting some "contrast agent" into the bloodstream of the patient.
- Dynamic infusion cavernosometry (DICC) is used to measure the vascular pressure in the corpus cavernosum during an erection. It is made by pumping fluid into the penis at a certain pressure and rate.
Treatment - from Generic Viagra to Intimate Exercises
Healthy Lifestyle and Underlying Diseases Treatment
It is obvious that the treatment methods are chosen depending on the cause of the problem. In some cases it can be solved quite easily. For example, if you are a smoker, quit this habit and you are likely to experience significant improvement. If you have troubles with blood circulation and lead a sedentary lifestyle, it makes sense to start doing physical exercises, particularly aerobic exercises.
Treating underlying diseases and physical conditions and healthy lifestyle changes should be the first line of treatment and take place before oral medications. Hormonal supplements can be prescribed to men who have low level of testosterone, when such lack of testosterone is the cause of erectile dysfunction. Usually in such situation men have low sexual desire. If impotence is caused by some medication taken by the patient, the problem can be solved by its alteration. In case if groin hernia is a cause of erection problems, surgical hernia repair is used.
Food that Provides Good Erection
There are products that are considered helpful for men’s sexual health:
- Watermelon fruit is able to have positive effect on the blood vessels and thus improve erection. Lycopene antioxidant in it is good for skin, heart and prostate.
- Oysters are full of zinc and boost testosterone levels and sex drive.
- Walnuts are full of arginine. The body uses this amino acid to make nitric oxide. Folic acid, vitamin E, and fiber are also present. Nuts are high in calories, so it is recommended to eat no more than a few small handfuls a day.
- Garlic keeps your arteries clear and healthy, thus providing adequate blood flow.
- Leafy greens give omega-3, minerals and vitamins. Kale is a booster of nitric-oxide and helps sex life.
- Chili peppers relax the arteries and allow the blood flow to the organs, including the penis, as well as lower cholesterol, blood pressure and prevent blood clots.
- Olive oil increases testosterone production in the body and removes bad cholesterol. Extra-virgin olive oil is the best choice.
They are also called pelvic floor exercises. Kegel exercises can be made both by men and women and are able to improve blood circulation, make the orgasms more intense, strengthen muscles below the bladder and prevent urinary incontinence, improve production of hormones by testicles and ovaries, keep the men’s prostate healthy, provide longer lasting sex.
They also help to significantly improve erectile function in 6 months at least for 40% of men, according to studies the University of the West in the U.K. Kegel exercises strengthen the bulbocavernosus muscle which helps empty the urethra after urination, pumps during ejaculation and engorges penis with blood during erection. There's no other way to train these intimate muscles, as common physical exercises do not have effect on them.
If you don’t feel the muscle that should be trained, try to stop your stream in the middle of urination, do it several times. The muscles clenched are the right ones. You should squeeze those muscles, then hold for five seconds, and finally relax. Sometimes try to hold your muscles squeezed for as long as a minute. Repeat this three times a day, at least 10 to 20 times. If you want you can do more repetitions (50-100) – you should gradually increase the amount of reps. They can be made in different positions – standing, sitting in a chair, lying down with knees up. The frequency of squeezes can also be alternated. The result can be seen in 1-3 weeks.
Your stomach, thigh muscles, or buttocks should not be strained. Don’t hold your breath. Relax well after each squeeze. Do both short and long squeezes. But don’t overdo, any muscle needs time to heal. You can do kegels 5-6 days a week and take one or two days off. At first you can feel discomfort, irritation and the desire to quit – it’s because your intimate muscles are weak and unmanageable. But after two or three days of training it will become easier.
Kegel exercises have significant advantages: you don’t have to pay money for them and they take minimum of time during the day. You can do them once or several times a day for several minutes, including when you are busy or you are watching TV. Kegel exercises can be made both as a treatment and as a preventive measure.
There’s one warning. Some men in chronic stress have a chronically tight pelvic floor. In this case, kegels can make the pelvic floor even tighter and worsen the situation. So, it is recommended that you consult a physician before starting kegel exercises. If he finds out that your pelvic floor is chronically tight, then massage, relaxation techniques and stretching will be useful. These measures can help get rid of premature ejaculation, hard-flaccid and other discomfort.
Oral medications include a group of phosphodiesterase type 5 inhibitors – the cyclic nucleotide phosphodiesterases. These are a group of enzymes existing in various molecular forms and unevenly distributed in the body. They are used because of their ability to destroy the cyclic nucleotides - cyclic guanosine monophosphate (cGMP) and cyclic adenosine monophosphate (cAMP). PDE5 is one of such enzyme forms, which increases blood flow by increasing cGMP in the blood supply to the penis. The PDE5 inhibitors are well-known: sildenafil (active constituent of Viagra), tadalafil (Cialis), and vardenafil (Levitra). Levitra, Cialis and Viagra are prescription drugs taken orally.
Topical medications are also used to treat erectile disfunction. Among them are topical creams like Vitaros (Canadian brand) that include alprostadil and DDAIP (enhancer of permeation).
Another treatment method is injection therapy. Medications as phentolamine, prostaglandin E1 and papaverine are injected into the penis. They relaxe the blood vessels, increase blood flow and produce an erection within 15 minutes.
Extracorporeal shockwave therapy is a non-surgical and non-drug method, and its advantage is absence of variety of side effects. This kind of therapy is used as well in cardiology, orthopedics and urology. It has been approved in Canada and most other countries in South America, Middle East, Europe, but not in U.S.A. yet.
Vacuum erection devices (pumps) apply negative pressure on the penis and thus draw blood into it. Penis pumps can be used just before sexual intercourse, if pharmacological methods turn out to be ineffective. After erection is attained by vacuum pump, it is maintained by means of compression ring which is placed around the base of the penis. Sometimes this method can cause slight bruising, so the majority of men prefer to try other methods first.
Surgery may be necessary in cases when erectile dysfunction results from injury - a car accident, etc., and repair (revascularisation) or removal of the penises’ blood vessels is necessary. This operation is usually made to young men, as in older age damaged blood vessels are more difficult to repair and there can be extensive damage. Only specially trained and experienced surgeons should do revascularisation operations.
Some men resort to alternative therapies and take medicines consisting of herbals and other natural products. It should be mentioned that such medications sometimes turn out to include synthetic chemical compounds. Besides, there were no scientific studies or clinical trials held to prove the effectiveness of alternative therapies.
If all treatments have failed, prosthetic implants (penile prostheses) are inserted into the penis. Such operation lasts for half an hour under general anesthesia. Implants can be made from various materials, for example, from silicone. Salt water (saline) fills up its cylinders. The cylinders act as a reservoir holding the saline next to the bladder. The patient uses the button in the scrotum to pump the device, and salt water from the reservoir fills the cylinders. This causes erection. To stop erection, the patient should press the button once more. Besides cylinder, another type of implant is a bendable rod making the penis rigid enough to have sex, but at the same time flexible enough to lie unobtrusively in the pants. The implant cannot be seen from the outside of the penis. There is no need to replace the implant, as these modern devices are made to work for many years. It is not recommended to insert an implant if there is an opportunity that some other treatment can help and that the sexual function can be regained, because such operation is an ‘end-of-the-line’ procedure. There’s a minor risk of the device’s mechanical failure, when it has to be repaired or removed from the penis, and a risk of infection and possible blood loss.
Psychotherapy or behavioral therapy will be helpful for those men whose troubles with erection come from psychological causes, when physical treatments give no effect. Psychotherapy can restore the lost sexual confidence and self-esteem which is very important for men. A man should not perceive his sexual dysfunction as a reflection of his masculinity or blame himself – it only makes the situation worse. He should not blame his partner either. Your sexual partner can also take part in your sex therapy; this can make you emotionally closer to each other. Another advice is not to focus on the intercourse itself, and to pay attention to other expressions of sexual intimacy as kissing, cuddling, massaging and caressing. This will help to reduce anxiety. A more relaxed approach to sex is what a man with erectile dysfunction needs. It can also make sense to completely refrain from penetrative sex for some weeks, concentrating on the foreplay and one’s sensations. This will lead to reduction of psychological pressure and anxiety, restoration of confidence, growth of passion and restoration of normal erection.
You should choose the appropriate treatment method together with your doctor.

Sometimes a higher dosage may help in such situation. Anyway, there’s no need to worry - subsequent attempts can be successful.
100mg, 50mg and 25mg are the dosages available. The recommended dose is 50mg a day. Alcohol and food can slow absorption of Viagra through the stomach, so it is not a good idea to take it on a full stomach or when you are drunk.

If your erection lasts for more than four hours or is painful, if you feel dizzy, have heart rhythm problems, or sudden vision loss, contact your doctor. To avoid side effects, do not take Levitra together with grapefruit, nitroglycerin, antibiotics, antifungal medicines, HIV/AIDS medicine, heart rhythm medicine, riociguat (Adempas).

The dosages are 5mg, 10mg and 20mg. The recommended dosage is 10mg.Taking Cialis with Adcirca, antibiotics, nitrates, antiviral or antifungal medicines, alcohol, grapefruit, can provoke unwanted side effects because of unpredicted interaction with tadalafil.
