It would be convenient if a fairy dickmother flew from the sky and told you this would be the drink that renders you flaccid, but when it comes to figuring out your limit, you’re on your own. There’s no hard and fast rule as to how much will actually affect you, either; Dr Mills notes that some men may be able to drink a lot and get erections, as everybody’s threshold is different.

Erectile dysfunction (ED) generally affects men older than 65, but younger men can get it too. If it happens at a younger age, ED may be a warning sign of another health issue. If you have no obvious risk factors and no other health problems, like diabetes, your doctor will run laboratory tests and may order heart tests. The same process that affects the arteries in the penis affects the ones in your heart, too. If something is wrong and it is not diagnosed and treated, you have a fairly high risk over the next four to five years of having some type of cardiac event.
An alprostadil cream that patients apply into the tip of the penis (the urethral meatus, the opening that urine passes through) is currently available in the UK and Europe. It is currently under review by the U.S. Food and Drug Administration (FDA). After application of the cream, an erection occurs within five to 30 minutes, and the erection lasts one to two hours in men who respond to the cream. Doctors recommend that one use the cream for a maximum frequency of two to three times per week and no more frequent than once every 24 hours. It has essentially the same contraindications and side effects as the other formulations of alprostadil. The cream may cause vaginal burning in roughly 4% of partners. Men should not use alprostadil cream for sexual intercourse with women of childbearing potential unless a condom is used. Researchers have performed controlled trial studies to evaluate the safety and effectiveness of this drug. Overall, 52% of men reported improvement in their erections compared to 20% of men receiving placebo. A later analysis demonstrated that 36% of men using the alprostadil cream had a clinically relevant improvement in vaginal penetration ability and 31% clinically relevant improvement in ability to have successful intercourse to ejaculation.
There are four main prescription-only medicines which are used to treat erectile dysfunction in young men: Viagra (sildenafil), Cialis, Levitra and Spedra. You can purchase all of these erectile dysfunction medicines through our discreet online service. They all work in roughly the same way, by opening up the arteries which supply blood to the penis. This allows blood to fill the erectile tissue in the penis, and for an erection to be achieved and maintained.

The causes of ED are numerous but generally fall into two categories: organic or psychogenic. The organic causes can be subdivied into five categories: vascular, traumatic/postsurgical, neurological, endocrine-induced, and drug-induced. Examples of the psychogenic causes are depression, performance anxiety, and relationship problems. In people with diabetes, the main risk factors are neuropathy, vascular insufficiency, poor glycemic control, hypertension, low testosterone levels, and possibly a history of smoking.

Erectile dysfunction in older men. Because erections primarily involve the blood vessels, it is not surprising that the most common causes in older men are conditions that block blood flow to the penis, such as atherosclerosis or diabetes. Another vascular cause may be a faulty vein, which lets blood drain too quickly from the penis. Other physical disorders, as well as hormonal imbalances and certain operations, may also result in erectile dysfunction.
And be aware that the vast majority of physical or psychological causes of erectile dysfunction are temporary. They may go away as quickly as they occurred. But if anything is bothering you or your partner, you should seek out confidential, professional advice. There is no point in worrying and not doing anything about it. It may just make the situation worse.

There is also a significant population, which has psychogenic sexual dysfunction, which is likely in a situation of marital conflict, which commonly exists in the families of alcoholics.[18] There is some evidence of this with more than a third of the subjects reporting dissatisfaction with their spouses' responses and / or decreased frequency. This cannot be conclusive without data on nocturnal erection or sexual activity in alternate situations. One of the limitations of this exploratory study is that marital functioning was not specifically assessed.


You might consider having a few drinks to get in the mood, but overindulging could make it harder for you to finish the act. Heavy alcohol use can interfere with erections, but the effects are usually temporary. The good news is that moderate drinking -- one or two drinks a day -- might have health benefits like reducing heart disease risks. And those risks are similar to erectile dysfunction risks.
While there are many ways to treat ED today, men with diabetes may require maximum doses of medications such as Viagra™, Cialis™, Levitra™ and Stendra™, yet still find drugs ineffective.7 In a study of nearly 20,000 men with ED, men with diabetes were 1.5 to 2 times more likely to move on to other treatments, such as pumps and penile implants than men without diabetes.9
Other medical therapies under evaluation include ROCK inhibitors and soluble guanyl cyclase activators. Melanocortin receptor agonists are a new set of medications being developed in the field of erectile dysfunction. Their action is on the nervous system rather than the vascular system. PT-141 is a nasal preparation that appears to be effective alone or in combination with PDE5 inhibitors. The main side effects include flushing and nausea. These drugs are currently not approved for commercial use.
As blood flows into the penis, the corpora cavernosa swell, and this swelling compresses the veins (blood vessels that drain the blood out of the penis) against the tunica albuginea. Compression of the veins prevents blood from leaving the penis. This creates a hard erection. When the amount of cGMP decreases by the action of a chemical called phosphodiesterase type 5 (PDE5), the muscles in the penis tighten, and the blood flow into the penis decreases. With less blood coming into the penis, the veins are not compressed, allowing blood to drain out of the penis, and the erection goes down.
Few men want to talk about their inability to get or maintain an erection, however, erectile dysfunction can have a profound impact on relationships and self-esteem. Fortunately, trouble in the bedroom doesn't necessarily mean you're dealing with erectile dysfunction. Most men will have problems with an erection at some point in their sexual history. But one bad day in the bedroom doesn't mean major sexual health problems. So how can you know if you're dealing with erectile dysfunction?
Prostaglandins (alprostadil): Alprostadil can be injected into the penis or inserted as a pellet through the urethra. It causes an erection without sexual stimulation that usually lasts about 60 minutes. The danger with this method is that too high a dose can cause priapism, an erection that won't go away. This condition requires immediate medical attention as it can cause serious bruising, bleeding, pain and permanent penile damage. Once the doctor is sure of the right dose, the man can self-inject at home.
In addition to these laboratory tests, your doctor may also ask you to complete a self-report to gauge your level of sexual function. You’ll be asked questions about your sexual desire (libido), your ability to achieve and maintain an erection, your ability to reach orgasm, your satisfaction level with intercourse, as well as your overall sexual satisfaction. Depending on your answers, and the results of your laboratory tests, your doctor may recommend a psychological evaluation to further explore the potential cause for your ED.
Cardiovascular diseases account for nearly half of all cases of erectile dysfunction in men older than 50 years. Cardiovascular causes include those that affect arteries and veins. Damage to arteries that bring blood flow into the penis may occur from hardening of the arteries (atherosclerosis) or trauma to the pelvis/perineum (for example, pelvic fracture, long-distance bicycle riding).
Erectile dysfunction in young men is an increasingly common chief complaint seen in urology clinics across the world (1). The international urologic community has taken an increased interest in this topic, with experts in the field of andrology and sexual dysfunction publishing multiple review articles (2,3) and an AUA Update Series Lesson (4) dedicated to this concerning issue. These articles skillfully address the epidemiology and diagnostic evaluation of ED and categorize ED (Table 1) into psychogenic or organic causes, addressing treatment options with specific interventions for each of the most common diagnoses.
This form of therapy has a response rate of well over 70%. The sympathetic nervous system normally maintains the penis in a flaccid or non-erect state. All of the vasoactive drugs, when injected into the corpora cavernosae, inhibit or override sympathetic inhibition to encourage relaxation of the smooth muscle trabeculae. The rush of blood engorges the penile corpora cavernosae sinusoidal spaces and creates an erection.
Is your erectile dysfunction due to psychological (stress, relationship problems, etc.) or physical factors? Your doctor may ask if you note erections at night or in the early morning. Men have involuntary erections in the early morning and during REM sleep (a stage in the sleep cycle with rapid eye movements). Men with psychogenic erectile dysfunction (erectile dysfunction due to psychological factors such as stress and anxiety rather than physical factors) usually maintain these involuntary erections. Men with physical causes of erectile dysfunction (for example, atherosclerosis, smoking, and diabetes) usually do not have these involuntary erections. Men with psychogenic erectile dysfunction may relate the onset of problems to a "stressor," such as failed relationship. Your doctor may suggest a test to determine if you have erections during sleep, which may suggest that there may be a psychological cause of the erectile dysfunction.
Surgery to repair arteries (penile arterial reconstructive surgery) can reduce impotence caused by obstructions that block the flow of blood to the penis. The best candidates for such surgery are young men with discrete blockage of an artery because of a physical injury to the pubic area or a fracture of the pelvis. The procedure is less successful in older men with widespread blockage of arteries.
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.

Researchers have found that one particular simple sugar, present in increased levels in diabetics, interferes with the chain of events needed to achieve and maintain erection and can lead to permanent penile impairment over time.  The results, which have implications for new types of erectile dysfunction treatments targeting this mechanism of erection, are described in the August 16 issue of the Proceedings of the National Academy of Sciences.
Erectile dysfunction started to become a household term after scientists discovered a drug to treat it. Nowadays, as anyone who watches TV can attest, there are several different medications for ED. Fifty to 70 percent of men with type 1 or type 2 diabetes respond to a class of drugs—including sildenafil (Viagra), var­denafil hydrochloride (Levitra), and tadalafil (Cialis)—called phosphodiesterase-5 inhibitors.
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.
Knowing about your history of ED will help your health provider learn if your problems are because of your desire for sex, erection function, ejaculation, or orgasm (climax). Some of these questions may seem private or even embarrassing. However, be assured that your doctor is a professional and your honest answers will help find the cause and best treatment for you.
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
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.
Having erection trouble from time to time isn't necessarily a cause for concern. If erectile dysfunction is an ongoing issue, however, it can cause stress, affect your self-confidence and contribute to relationship problems. Problems getting or keeping an erection can also be a sign of an underlying health condition that needs treatment and a risk factor for heart disease.
Depression. The profound sadness, emptiness, and hopelessness that characterize depression may also cause ED among younger men. “The biggest effect of depression is on a man’s desire for sexual relations, or libido,” says Drogo Montague, MD, director of the Center for Genitourinary Reconstruction in the Glickman Urological and Kidney Institute at the Cleveland Clinic. “To some extent, depression can affect a man’s ability to maintain an erection. It can be a chicken-and-egg situation. However, reduced libido is a common indicator of depression.”
Diabetes mellitus: Erectile dysfunction tends to develop 10 to 15 years earlier in diabetic men than among nondiabetic men. The increased risk of erectile dysfunction among men with diabetes mellitus may be due to the earlier onset and greater severity of atherosclerosis (hardening of the arteries) that narrows the arteries and thereby reduces the delivery of blood to the penis. Atherosclerosis can affect the arteries in the penis, as well as the arteries in the pelvis that supply the penile arteries. Diabetes mellitus also causes erectile dysfunction by damaging nerves that go to the penis, much like the effect of diabetes on nerves in other areas of the body (diabetic neuropathy). Diabetes can also affect the muscles in the penis, leading to troubles with erections. Smoking cigarettes, obesity, poor control of blood glucose levels, and having diabetes mellitus for a long time further increase the risk of erectile dysfunction in people with diabetes.
The initial step in evaluating ED is a thorough sexual history and physical exam. The history can help in distinguishing between the primary and psychogenic causes. It is important to explore the onset, progression, and duration of the problem. If a man gives a history of “no sexual problems until one night,” the problem is most likely related to performance anxiety, disaffection, or an emotional problem. Aside from these causes, only radical prostatectomy or other overt genital tract trauma causes a sudden loss of male sexual function.
Taking one of these tablets will not automatically produce an erection. Sexual stimulation is needed first to cause the release of nitric oxide from your penile nerves. These medications amplify that signal, allowing some men to function normally. Oral erectile dysfunction medications are not aphrodisiacs, will not cause excitement and are not needed in men who get normal erections.
A 25-year-old male presents with a past medical history of mild traumatic brain injury, remote bilateral orchitis, depression, anxiety, and PTSD from childhood bullying. He presents with his mother. His chief complaint is ED that began at 19 years old. He reports that it is "hard to obtain an erection, takes a lot of work to get almost nothing out of it" and “extreme loss of sensation in specific areas” on his penis. He feels that this might be related to “over masturbation without lubricant” 1–3 times per day and reports that he is “addicted to masturbation”, using it as a coping mechanism to manage his PTSD. He reports strong, sustainable erections with tadalafil 5 mg and recovery of sensation when he uses marijuana. He has read extensively on the internet and self-treats with topical vitamin creams, self-administered laser treatment to the penis, pulsed electromagnetic therapy, and hyperbaric oxygen treatment for ED for the past 6 months. He reports no change with any of these treatments. He reports reduced libido and has recently started treatment with HCG and testosterone gel for testosterone of 198 without any change in his symptoms with T of 450. His free T is normal. He lives at home, is unemployed, and is sedentary. He takes Wellbutrin. His physical examination is normal. His CBC, CMP, pituitary, and thyroid functions are normal. Prior to the visit, his mother called the clinic to inform personnel that her son was very sensitive, potentially suicidal, and emotionally disturbed by this problem. He has seen two other urologists already for his erectile dysfunction and been displeased with the outcome of his visits.
