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.
Failure to achieve an erection is not uncommon for most men and may be considered normal even if it happens as often as 20 percent of the time. There is a wide range of normal when it comes to sexual functioning and sexual relationships. "Generally if a couple feels comfortable with their sex life and they enjoy intimacy together, erectile dysfunction may not be much of an issue. But if erectile dysfunction is causing stress in a relationship, then help is available," says Feloney.
To give you some evidence of the link between anxiety, stress, and ED consider the results of a study published in a 2015 edition of Comprehensive Psychiatry. In a study of case records for 64 men with erectile dysfunction or premature ejaculation, there was a significant link between ED and anxiety disorders or depression. Of the 64 participants, 8 had comorbid depressive disorders and 15 had anxiety disorders. In the majority of patients, these disorders predated the onset of sexual dysfunction which suggests that the disorders may have been a contributing factor.
Tobacco use though, was not found to be a significant determinant of sexual dysfunction. This is contrary to all reported evidence. 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.
In most young men with ED, additional testing to assess for the origin of ED is unnecessary as the history gives you the information that you need. With this said, it may be therapeutic for the patient to know his laboratory assessments are normal, in which case additional testing does add significant value to the assessment. From the history alone, we find that most of these men will have situational erectile dysfunction that responds well to low dose oral PDE-5 inhibitors. If the patient does respond well to these medications, the diagnosis of neurogenic erectile dysfunction, clinically significant arterial insufficiency, or venous-occlusive dysfunction can efficiently be ruled out. If the patient responds inconsistently or does not respond to the oral medications, additional workup should be considered, dependent on the additional history provided.
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.
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.
Lifestyle choices that impair blood circulation can contribute to ED. Smoking, excessive drinking, and drug abuse may damage the blood vessels and reduce blood flow to the penis. Smoking makes men with atherosclerosis particularly vulnerable to ED. Being overweight and getting too little exercise also contribute to ED. Studies indicate that men who exercise regularly have a lower risk of ED.
For patients who have ED related to hypertonic cavernous smooth muscle and excessive sympathetic discharge, we recommend a trial of a low-dose alpha adrenergic blocker, such as terazosin 1 mg PO at bedtime nightly. We typically increase the dosage as needed every 2–3 weeks for 3–5 months until the patient experiences improvement of the erection or we determine that treatment is ineffective. We explain the potential side effects of orthostasis, dizziness, and retrograde ejaculation in detail. We also take great care and time in explaining to the patient, and his family/partner if present, the pathophysiologic mechanism of their erectile dysfunction and the biological basis of the treatment plan. This detailed discussion helps to engage the patient in the treatment plan and provides encouragement regarding the potential for response to treatment and recovery. During these encounters, we utilize teaching tools, such as diagrams, drawings, printed handouts, and other visual aids to ensure that the discussion is patient-focused and patient-friendly. Patient education is critical to exploring treatment options and developing confidence in our ability to treat the ED, and their own ability to overcome and eventually resolve the problem of ED.
Talk with your doctor before trying supplements for ED. They can contain 10 or more ingredients and may complicate other health conditions. Asian ginseng and ginkgo biloba (seen here) are popular, but there isn't a lot of good research on their effectiveness. Some men find that taking a DHEA supplement improves their ability to have an erection. Unfortunately, the long-term safety of DHEA supplements is unknown. Most doctors do not recommend using it.
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 penis contains three cylinders, the two corpora cavernosa, which are on the top of the penis (see figure 1 below). These two cylinders are involved in erections. The third cylinder contains the urethra, the tube that the urine and ejaculate passes through, runs along the underside of the penis. The corpus spongiosum surrounds the urethra. Spongy tissue that has muscles, fibrous tissues, veins, and arteries within it makes up the corpora cavernosa. The inside of the corpora cavernosa is like a sponge, with potential spaces that can fill with blood and distend (known as sinusoids). A layer of tissue that is like Saran Wrap, called the tunica albuginea, surrounds the corpora. Veins located just under the tunica albuginea drain blood out of the penis.
The urologist must discuss the topic of ED delicately and caringly in order to earn the patient’s trust and be permitted to address his problem (15). It is important early during the visit to engage the patient and provide him reassurance that you will work as a team to evaluate and treat his disorder. A detailed history is the most important component of the evaluation. A thorough sexual history has many components. It should begin with information regarding onset, duration, severity, patient-suspected etiology of the ED. Ask the patient to define his specific concerns. The term “erectile dysfunction” is very broad, and the patient may actually have arousal issues or ejaculatory concerns or a combination of concerns. Ask specific questions regarding erectile hardness and sustainability during self-stimulation versus with a partner (global versus situational ED). Determine if the patient has ED in certain positions (lying down versus upright or seated). Inquire about libido and nocturnal erections. It is also important to ask the patient about past treatments and response. Inquire about any concomitant pain issues, irritative or obstructive voiding symptoms, or pelvic floor complaints.
Our team includes a sex advisor/counselor who can help you understand what is making you anxious around sex, and give you techniques to decrease your anxiety about sex. He has also helped many of our younger patients get better at sex. We also have an exercise physiologist, who will work with you on both diet and exercise, which can have a profound effect on the quality of your erections.
After a full history and physical examination, the urologist likely has a perception of the etiology of the problem. Additional laboratory evaluations may be necessary to evaluate for specific types of organic disease. These tests might include serum chemistry, complete blood count, lipid profile, thyroid stimulation hormone/free thyroxine, and early morning serum testosterone to assess for metabolic abnormalities, such as diabetes mellitus, hyperlipidemia, renal dysfunction, thyroid disease, and hypogonadism (16). These are not mandatory components of the assessment in a patient with hypertonic cavernous smooth muscle as the source of ED.
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.
Some doctors prefer to start a man on the lowest dose of an oral medicine and increase the dose until an effective one is found. Others prefer to start with the highest dose and go to a lower dose only if a man complains of side effects. In either case, it’s important for a man to communicate with his doctor to let him know how the dose he’s using is working.
In the evaluation of physical causes of ED, the health care provider is assessing for conditions that may affect the nerves, arteries, veins, and functional anatomy of the penis (for example, the tunica albuginea, the tissue surround the corpora). In determining a physical (or organic) cause, your health care provider will first rule out certain medical conditions, such as high blood pressure, high cholesterol, heart and vascular disease, low male hormone level, prostate cancer, and diabetes, which are associated with erectile dysfunction. Medical/surgical treatment of these conditions may also cause ED. In addition to these health conditions, certain systemic digestive (gastrointestinal) and respiratory diseases are known to result in erectile dysfunction:
"One of the reasons erectile dysfunction increases with age is that the diseases that lead to it also increase with age," notes Dr. Feloney. Evaluating the causes of erectile dysfunction starts with your doctor taking a good health history and giving you a physical exam. Common medical issues that can lead to erectile dysfunction include diabetes, high blood pressure, hardening of the arteries, low testosterone, and neurological disease. Talk to your doctor about better managing these health conditions.
In many ways, performance anxiety becomes a self-fulfilling prophecy wherein you become nervous about being able to satisfy your partner and the nerves lead to sexual dysfunction. In many cases, performance anxiety is triggered by negative self-talk – worries about being able to achieve an erection, pleasing a partner, or ejaculating too early. If you have had erectile issues in the past, those experiences will add to the weight of performance anxiety.
Sexual dysfunction appears to be common among male subjects with alcohol dependence. Seventy-two per cent of the subjects with alcohol dependence complained of one or more problems with sexual functioning. This is similar to what has been reported in earlier studies.[10,16] Multiple co-existing dysfunctions seemed to be the norm in the sample studied. The most common condition reported in our study was premature ejaculation followed closely by low sexual desire and erectile dysfunction.
Until recently, erectile dysfunction (ED) was one of the most neglected complications of diabetes. In the past, physicians and patients were led to believe that declining sexual function was an inevitable consequence of advancing age or was brought on by emotional problems. This misconception, combined with men’s natural reluctance to discuss their sexual problems and physicians’ inexperience and unease with sexual issues, resulted in failure to directly address this problem with the majority of patients experiencing it.
Your ability to orgasm is not connected to the prostate gland, although a man who has had a radical prostatectomy will have a dry orgasm with no ejaculation. As long as you have normal skin sensation, you should be able to have an orgasm with the right sexual stimulation. This means that treating your ED should allow you to resume a normal, healthy sex life.
Erectile dysfunction can be embarrassing and difficult to talk about for some men. Many men may feel like they need to hide their diagnosis from their partner. "Failure to communicate openly about erectile dysfunction can result in both partners drawing away from the relationship," warns Feloney. Remember that your partner is also affected by your problem; being open and honest is the best way to decrease fear and anxiety. Discuss options for achieving sexual satisfaction together, and be positive — most erectile dysfunction problems can be treated.
I think that a very powerful argument to young men who want to perform at the highest level is to point out the destructive nature of what they’re doing. If they’re having 18 drinks per week, if they’re having three, four, five drinks at any one time, they’re going to guarantee that their erections are not going to be at the highest level. I can’t tell you the number of men who come in saying, they went out, they had a date, they had a big dinner– which, by the way, is also not a great thing for erections, because all the blood is now going to your gut instead of to the genital area. And how important lifestyle changes are to improving your performance, as well, if not better, than the medications. So make certain that you exercise modestly, not excessively. Make certain that you have a smaller meal on an evening or a day that you want to have a sexual encounter, because you want the blood to go, once again, to the penile area and not to your gut. And really, the whole idea of stress– if you’re stressed out, if you’re worried about a lot of things, if you’re distracted, you can’t initiate that psychic stimulus to your spinal cord and then ultimately to your penis. So stress management is incredibly important.
ED has been for long time considered a problem mainly related to psychological conditions and distress. Accordingly, until phosphodiesterase type 5 inhibitors (PDE5i) were introduced, psychoanalysis and cognitive-behavioural therapy were the only option for ED. In the last few decades, ED has been recognized as a clinical consequence of several different organic diseases and the importance of vascular health in erectile function has been so emphasized that ED is now considered not only the result of vascular impairment, but also a harbinger of forthcoming cardiovascular (CV) events (17). Despite the increasing attention of research towards organic mechanisms and conditions leading to ED, it is now known that considering this symptom as entirely due to organic disorders, is as imprecise as considering it only secondary to psychological conditions. In fact, this pathogenetic dichotomy is now obsolete (1,18,19), because it is now known that ED is a multidimensional disorder deriving from the interaction of different components related to organic conditions, relational context and psychological status (20,21). Even when only one of these components is involved in the initial development of erectile impairment, eventually the other ones will appear, thus further worsening ED (21-23). The multidimensional nature of ED is still not fully accepted by health care professionals when dealing with young patients. In fact, complaints of ED in young men is often underestimated and attributed to transient and self-limiting psychological conditions, such as performance anxiety. Young patients are often reassured without any further medical investigations, including physical exam. However, organic disorders, as well as relational and psychological or psychiatric conditions, can be meaningful in determining ED in younger men. In a population of subjects seeking medical care at the Sexual Medicine and Andrology Unit of the University of Florence for sexual dysfunction, the first tertile of age (n=1,873 subjects) represents younger subjects (18–44 years). Pathogenetic components of ED in our sample are investigated by the Structured Interview on Erectile Dysfunction (SIEDY), a structured interview including 13 questions, whose answers, organized in a Likert scale, provide three scales, one for the organic subdomain [(SIEDY Scale 1); (22)], one for the relational subdomain [(SIEDY Scale 2); (23)] and one for the intrapsychic subdomain [(SIEDY Scale 3); (21)]. According to these scale scores, organic, relational and intrapsychic conditions are all significant risk factors for ED in younger patients of our population (Figure 2).
A 2013 study published in The Journal of Sexual Medicine evaluated 439 men for erectile dysfunction and compared ED causes and frequency in men 40 or younger to men over 40. They found that 26 percent of the younger men had ED. Although these men were healthier and had higher levels of testosterone than the older men, they were more likely to be smokers or to have used illicit drugs. In almost half of the younger men with ED, the ED was considered severe.
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.
Luckily, awareness of ED as a significant and common complication of diabetes has increased in recent years, mainly because of increasing knowledge of male sexual function and the rapidly expanding armamentarium of novel treatments being developed for impotence. Studies of ED suggest that its prevalence in men with diabetes ranges from 35–75% versus 26% in general population. The onset of ED also occurs 10–15 years earlier in men with diabetes than it does in sex-matched counterparts without diabetes.
medicines called alpha-blockers such as Hytrin (terazosin HCl), Flomax (tamsulosin HCl), Cardura (doxazosin mesylate), Minipress (prazosin HCl), Uroxatral (alfuzosin HCl), Jalyn (dutasteride and tamsulosin HCl), or Rapaflo (silodosin). Alpha-blockers are sometimes prescribed for prostate problems or high blood pressure. In some patients, the use of Sildenafil with alpha-blockers can lead to a drop in blood pressure or to fainting
When you become aroused, your brain sends chemical messages to the blood vessels in the penis, causing them to dilate or open, allowing blood to flow into the penis. As the pressure builds, the blood becomes trapped in the corpora cavernosa, keeping the penis erect. If blood flow to the penis is insufficient or if it fails to stay inside the penis, it can lead to erectile dysfunction.
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).
A daily glass of wine, beer or single malt over dinner or after work with your buddies will not lead to erectile dysfunction (ED), inability to get or maintain an erection during sex. Overindulging, though, will short-circuit your sex life. Besides waking up with a major hangover, overdoing it will eventually lead to hardening of the arteries and cardiovascular disease, which interferes with blood flow to your equation is simple: the less blood flow, the soft and skimpier the erection. Unless you can drink in moderation, avoid alcohol if you want to be at your best in bed.
