Tadalafil should not be used with alpha-blockers (except Flomax), medicines used to treat high blood pressure, and benign prostate hypertrophy (BPH) because the combination of tadalafil and an alpha-blocker may lower the blood pressure greatly and lead to dizziness and fainting. Examples of alpha-blockers include tamsulosin (Flomax), terazosin (Hytrin), doxazosin (Cardura), alfuzosin (Uroxatral), and prazosin (Minipress). Tamsulosin (Flomax) is the only alpha-blocker that patients can use safely with tadalafil. When tadalafil (20 mg) was given to healthy men taking 0.4 mg of Flomax daily, there was no significant decrease in blood pressure and so patients on this dose of tamsulosin (Flomax) can be prescribed tadalafil. The only alpha-blocker not tested with tadalafil is alfuzosin (Uroxatral), and no recommendations can be made regarding the interaction between the two.
ED is often the result of atherosclerosis, and as a result, men with ED frequently have cardiovascular disease. Sexual activity is associated with increased physical exertion, which in some men may increase the risk of having a heart attack (myocardial infarction or MI). The major risk factors associated with cardiovascular disease are age, hypertension, diabetes mellitus, obesity, smoking, abnormal lipid/cholesterol levels in the blood, and lack of exercise. Individuals with three or more of these risk factors are at increased risk for a heart attack during sexual activity. The Princeton Consensus Panel developed guidelines for treating ED in men with cardiovascular disease. Thus, if you have ED and cardiovascular disease (for example, angina or prior heart attack), you should discuss whether or not treatment of ED and sexual activity are appropriate for you.

Erectile dysfunction (ED) is commonly called impotence. It’s a condition in which a man can’t achieve or maintain an erection during sexual performance. Symptoms may also include reduced sexual desire or libido. Your doctor is likely to diagnose you with ED if the condition lasts for more than a few weeks or months. ED affects as many as 30 million men in the United States.
"Sexual relations are not only an important part of people's wellbeing. From a clinical point of view, the inability of some men to perform sexually can also be linked to a range of other health problems, many of which can be debilitating or potentially fatal," says Professor Gary Wittert, Head of the Discipline of Medicine at the University of Adelaide and Director of the University's Freemasons Foundation Centre for Men's Health.
“Although having sex at 70 is not the same as having sex at 20, erectile dysfunction is not a normal part of aging,” according to Michael Feloney, MD, urologic surgeon and expert on sexual dysfunction issues at the Nebraska Medical Center in Omaha. “You should still be able to have a satisfying sex life as you age." If you are experiencing erectile dysfunction, these 10 dos and don'ts may help.
For an adult, there are not too many effects of diet on growth and development, but for children effects can be dramatic. The adolescent body needs a certain amount of protein, vitamins, and fat for healthy development. Speak to a pediatrician before putting a child on a diet. For an adult, if you are obese, use a high protein diet, but only for a short time to jump start weight loss, then move to a healthy eating program.
Erosion of the prosthesis, whereby it presses through the corporal tissue into the urethra, may occur. Symptoms and signs may include pain, blood in the urine, discharge, abnormal urine stream, and malfunction. If the prosthesis erodes into the urethra, a physician must remove it. If the other cylinder remains intact, it can be left in place. A physician leaves a catheter in place to allow the urethra to heal.
The common PDE5 inhibitor drugs approved in the United States are sildenafil (Viagra), vardenafil (Levitra and Staxyn, the generic form), tadalafil (Cialis), or avanafil (Stendra). All of the currently approved PDE5 inhibitors work in the same way. They differ in the number of available doses, how quickly they work and last in your system, the dosing, and to some extent in the side effects. However, they generally share the same indications and contraindications. Currently, tadalafil is the only medication that patients can take on a daily basis and is approved for the treatment of both ED and BPH (benign enlargement of the prostate).
Tobacco use though, was not found to be a significant determinant of sexual dysfunction. This is contrary to all reported evidence.[19] This finding is most likely to be due to our treatment of tobacco use as a categorical (present / absent) variable in a situation where almost 90% of the sample was using tobacco. Future studies need to use indices of severity to avoid this error.
Cigarette smoking is a risk factor for ED, according to the 2014 Report of the U.S. Surgeon General. Excess weight can also contribute to erectile dysfunction. A 2004 Italian study found that one-third of their 110 obese study subjects were able to eliminate their erectile dysfunction problems by losing fifteen percent of their weight through diet and exercise.

Circulatory problems: An erection occurs when the penis fills with blood and a valve at the base of the penis traps it. Diabetes, high blood pressure, cholesterol, clots, and atherosclerosis (hardening of the arteries) can all interfere with this process. Such circulatory problems are the number one cause of erectile dysfunction. Frequently, erectile dysfunction is the first noticeable symptom of cardiovascular disease.


The National Institutes of Health estimates that erectile dysfunction strikes as many as 30 million men in the United States. Its prevalence does increase with age — 4 percent of men in their 50s are affected by ED, 17 percent in their 60s, and 47 percent of those over 75. But research has also found that 5 percent of those affected were between 20 and 39.

Performance anxiety can be another cause of impotence. If a person wasn’t able to achieve an erection in the past, he may fear he won’t be able to achieve an erection in the future. A person may also find he can’t achieve an erection with a certain partner. Someone with ED related to performance anxiety may be able to have full erections when masturbating or when sleeping, yet he isn’t able to maintain an erection during intercourse.
A medical history focused on risk factors, such as cigarette smoking, hypertension, alcoholism, drug abuse, trauma, and endocrine problems including hypothyroidism, low testosterone levels, and hyperprolactinemia, is very important. Commonly used drugs that disrupt male sexual function are spironolactone (Aldactone), sympathetic blockers such as clonidine (Catapres), guanethidine (Islemin), methyldopa (Aldomet), thiazide diuretics, most antidepressants, ketoconazole (Nizoral), cimetidine (Tagamet), alcohol, methadone, heroin, and cocaine. Finally, assessment of psychiatric history will help identify emotional issues such as interpersonal conflict, performance anxiety, depression, or anxiety.

A sexually competent male must have a series of events occur and multiple mechanisms intact for normal erectile function. He must 1) have desire for his sexual partner (libido), 2) be able to divert blood from the iliac artery into the corpora cavernosae to achieve penile tumescence and rigidity (erection) adequate for penetration, 3) discharge sperm and prostatic/seminal fluid through his urethra (ejaculation), and 4) experience a sense of pleasure (orgasm). A man is considered to have ED if he cannot achieve or sustain an erection of sufficient rigidity for sexual intercourse. Most men, at one time or another during their life, experience periodic or isolated sexual failures. However, the term “impotent” is reserved for those men who experience erectile failure during attempted intercourse more than 75% of the time.
All three of these involve specific bodily systems including the hormones, muscles, blood vessels, nervous system, and emotions. If any of these systems become compromised, it can cause ED. In the case of anxiety and stress, these things can affect the brain’s ability to send the necessary signals to trigger the desired physical response – an erection. Stress and anxiety can also contribute to an ongoing cycle of ED, as mentioned earlier.
There was a significant reduction in the frequency of sexual intercourse per week over the last five years having decreased from a mean of 4.6 (± 2.6) times per week to 2.2 (± 2.2) times per week currently. Forty-eight per cent of the sample had more than one sexual dysfunction. Of the 24 subjects with only one complaint, the most frequent complaint was that of premature ejaculation in 18 subjects.
Occasional difficulties in bed do not constitute ED – it is the persistent and consistent inability to maintain an erection through satisfactory intercourse. It is more common than men might think, given that they are loath to discuss it with others, often even their doctors. The condition has many causes and, as a result, affects men of all ages – though it becomes increasingly prevalent with age.

The recommended starting dose of tadalafil for use as needed for most patients is 10 mg taken orally approximately one hour before sexual activity. A doctor may adjust the dose higher to 20 mg or lower to 5 mg depending on efficacy and side effects. Doctors recommended that patients take tadalafil no more frequently than once per day. Some patients can take tadalafil less frequently since the improvement in erectile function may last 36 hours. Patients may take tadalafil with or without food. Tadalafil is currently the only PDE5 inhibitor that is FDA-approved for daily use for erectile dysfunction and is available in 2.5 mg or 5 mg dosages for daily use.
Before a man concludes that oral drugs don’t work for him, he should have his testosterone levels checked to rule out hormone deficiency as the cause of (or as a contributor to) his sexual dysfunction. Other symptoms of low testosterone include a low sex drive and infertility. Checking testosterone levels requires a blood test. If a man’s levels of testosterone are decreased or at the lower end of normal, his doctor may prescribe supplemental testosterone therapy, either as testosterone injections or testosterone gel, which is applied daily to the skin. In some cases, testosterone therapy alone can resolve sexual dysfunction, or it can be combined with the use of oral erectile dysfunction drugs.
Hormonal disorders, such as low testosterone, may contribute to ED. Another possible hormonal cause of ED is increased production of prolactin, a hormone produced by the pituitary gland. Additionally, an abnormally high or low thyroid hormone level can result in ED. Young men who use steroids to help build muscle mass are also at a higher risk for ED.
The study, led by the University of Exeter and the University of Oxford, looked at data on more than 220,000 men across three cohorts, 6,000 of whom experienced erectile dysfunction. The research echoed recent findings that erectile dysfunction has a genetic cause, and goes further by opening the possibility that living a healthier lifestyle may help reduce risk.
As shown in Figure 2, in younger patients consulting for ED, the organic component plays the predominant role. These data provide evidence for the need to adequately investigate possible organic causes of ED in younger and apparently fit men. The organic causes of ED can be classified into three categories: metabolic and CV, endocrine and neurologic conditions.

Control your blood sugar through your diet. Eating a diabetes-friendly diet will help you better control your blood sugar levels and lessen the amount of damage to your blood vessels and nerves. A proper diet geared at keeping your blood sugar levels in check can also improve your energy levels and mood, both of which can help reduce the risk of erectile dysfunction. You may consider working with a dietitian who is also a certified diabetes educator to help adjust your eating style.
Finding a satisfying solution to ED can be a life-changing event for many men and their partners. In one study of 200 patients and 120 partners, both men and their partners found the AMS 700 penile implant to be satisfying. 92% of patients and 96% of their partners reported sexual activity to be excellent or satisfactory.10 Talk to your doctor about your treatment options.
Oftentimes, after a thorough history and physical examination, additional diagnostic testing is not necessary to categorize ED (17). Depending on concerns raised from the history and physical examination, directed lab-work or additional studies may be conducted to ensure that the patient does not have medical disease that might be causing ED. All men with suspected vasculogenic erectile dysfunction deserve a cardiovascular assessment (18).
Ageing is one of the most important unmodifiable risk factors for the development of metabolic disorders and CV diseases. Accordingly, the common algorithms for the estimation of risk of forthcoming diabetes or CV events include age as a factor of the equations (24-29). The weight attributed to age for estimating the risk in these equations is often so significant that younger men are automatically considered at low risk, irrespective of the other possible risk factors. However, even in younger subjects, overlooking the contribution of cardio-metabolic factors to pathogenesis of ED is a mistake that can lead to the loss of the opportunity of early recognition of patients who deserve a change in life-style or a pharmacological correction of risk factors. ED, besides being considered one of the clinical manifestations of metabolic and cardiovascular diseases (CVD), is regarded as an early marker of CV events (17). In fact, according to Montorsi’s hypothesis (30), impairment of penile artery blood flow occurs before that of coronary or carotid arteries, whose diameter is greater and needs longer time to acquire a clinically relevant damage. The clinical consequence of this pathological event is that ED often manifests earlier than myocardial infarction or stroke. In particular, it has been demonstrated that ED occurs on average three years before the first major adverse CV event (MACE) (31). Quite surprisingly, although CV risk increases with ageing, the role of ED as a harbinger of forthcoming MACE becomes progressively less evident. Data derived from almost 2,500 community-dwelling men aged 40–79 years, involved in the Olmsted County study show that ED is associated with an almost 50-fold higher risk of incident heart diseases in men aged 40–49 years, whereas the difference in risk between ED and non-ED men progressively declines in older men (32). The different CV risk associated with ED in different age bands has been confirmed by the meta-analysis of the available longitudinal studies (33). These observations suggest that, in younger men, the role of ED as a marker of CV risk is even more dramatic than in older ones and as a consequence, investigating the presence of metabolic or CV conditions in younger ED patients is pivotal for identifying men in whom an early life-style modification may avoid serious CV consequences. Even more than erection during sexual intercourse, erection during masturbation is considered a physiologic function that mirrors metabolic and CV health. In fact, erections during masturbation are far less affected by relational and psychological components than sex-related ones (34). In a population of subjects attending the Sexual Medicine and Andrology Unit of the University of Florence for sexual dysfunction, more than 2,500 men reported autoeroticism in the previous 3 months. Among these men, the impairment of erection during masturbation was associated with family and personal history of CVD (35), as well as with impaired response to the test with the intracavernous injection (ICI) of prostaglandin E1, which suggests an arteriogenic damage of penile arteries and predicts forthcoming MACE (36). For a subset of these men (n=862), information on the occurrence of MACE during a mean follow-up of 4.3 years was available and those who reported impaired erections during masturbation had a significantly higher incidence of MACE (35). However, when considering separately younger and older men, this association was confirmed only in younger ones, and it was still significant after excluding men reporting severe ED during masturbation (35). This suggests that the impairment of erection during masturbation is a symptom not completely overlapping with sex-related ED and that it can provide different and supplementary information, in particular when assessed in younger and apparently healthy men. Similarly to what is observed for erection during masturbation, acceleration of blood in penile arteries, as measured by the colour Doppler ultrasound in flaccid conditions, is associated with an adverse CV profile in men consulting for ED. A reduction in flaccid acceleration, which can be used by clinicians to objectively verify the arteriogenic origin of ED and to characterize the extent of a self-reported symptom, has been also associated with a future risk of CV events, with the association being significant in younger but not in older men (37).
Vacuum devices for ED, also called pumps, offer an alternative to medication. The penis is placed inside a cylinder. A pump draws air out of the cylinder, creating a partial vacuum around the penis. This causes it to fill with blood, leading to an erection. An elastic band worn around the base of the penis maintains the erection during intercourse.
It's tempting to think of erectile dysfunction (ED) as a condition that only affects aging men. But a small number of younger men will develop erectile dysfunction too. One survey found that about 2 percent of men in their 20s are unable to have erections. Overall, 6.5 percent of these younger males said they had at least occasional difficulty getting or sustaining an erection.

Some men should not take PDE5 inhibitors. They can cause hypotension (abnormally low blood pressure that can lead to fainting and even shock) when given to patients who are taking nitrates (medications taken for heart disease). Therefore, patients taking nitrates daily should not take any of the PDE5 inhibitors. Nitrates relieve angina (chest pain due to insufficient blood supply to the heart muscle because of narrowing of the coronary arteries); these include nitroglycerine tablets, patches, ointments, sprays, and pastes, as well as isosorbide dinitrate and isosorbide mononitrate. Other nitrates such as amyl nitrate and butyl nitrate also are in some recreational drugs called "poppers."


Experts often treat psychologically based impotence using techniques that decrease anxiety associated with intercourse. The patient's partner can help apply the techniques, which include gradual development of intimacy and stimulation. Such techniques also can help relieve anxiety during treatment of physical impotence. If these simple behavioral methods at home are ineffective, a doctor may refer an individual to a sex counselor.
When we say it’s a barometer of men’s health, it’s a signal. It’s an indicator that things may be right or not. And so when a man develops an erectile problem– and we’re talking about something that is occurring over time. It’s not something that just occurred overnight. When it occurs overnight, it’s more often than not a psychogenic, an anxiety reaction.

Similar to the general population (58), in subjects consulting for sexual dysfunction, T deficiency is progressively more prevalent as a function of age (50). In a series of 4,890 subjects consulting our Sexual Medicine and Andrology Unit for sexual dysfunction, one in five (19.6%) and one in three (29.4%) patients have total T below 10.4 and 12 nmol/L, respectively (60). Clinical correlates of T deficiency show different figures according to patient’s age. In fact, we previously demonstrated that in the youngest quartile (17–42 years old), but not in the oldest one (62–88 years old), severity of reported ED and penile blood flow impairment (dynamic peak systolic velocity) were not associated to decreasing testosterone levels (50). It is possible to speculate that, in young individuals, intercourse-related penile erection is such a complex phenomenon that other determinants (i.e., intrapsychic or relational) might mask its androgen regulation and that T deficiency produces greater sexual disturbances in subjects with greater frailty, such as older individuals. However, reported frequency of spontaneous erection and sexual thoughts were significantly decreased as a function of T decline even in younger subjects (50). Moreover, in young individuals low T was associated with a worse metabolic profile, including hypertriglyceridemia and increased waist circumference (50). Accordingly, the prevalence of MetS in the youngest quartile was clearly associated with T deficiency, as it was in the older quartiles (50). Therefore, T deficiency must be accurately verified in all subjects consulting for sexual dysfunction, even in the youngest ones.


The lab testing obtained for the evaluation of erectile dysfunction may vary with the information obtained on the health history, physical examination, and recent lab testing. A testosterone level is not necessary in all men; however, a physician will order labs to determine a patient's testosterone level if other signs and symptoms of hypogonadism (low testosterone) such as decreased libido, loss of body hair, muscle loss, breast enlargement, osteoporosis, infertility, and decreased penile/testicular size are present.
Erectile Dysfunction is typically caused by a problem with blood flow in the penis due to the hardening and narrowing of the blood vessels of the penis. This occurs most commonly due to aging itself, which causes the smooth muscle cells that line the blood vessels to become stiffer and less able to stretch. This prevents the flow of blood that the penis requires to become erect.
Look, ED can have many causes. Most of the time, it’s physiological. But there are also lots of psychological reasons why someone may experience ED. Treating ED isn’t all about medication. Dealing with some of these psychological issues can help you battle ED, too. I’m talking about depression, anxiety, loss of desire, sense of inadequacy, guilt, fatigue, anger, relationship dysfunction. Working through these types of psychological challenges can help you achieve the happy, healthy manhood you deserve.
