*All medications have both common (generic) and brand names. The brand name is what a specific manufacturer calls the product (e.g., Tylenol®). The common name is the medical name for the medication (e.g., acetaminophen). A medication may have many brand names, but only one common name. This article lists medications by their common names. For information on a given medication, check our Drug Information database. For more information on brand names, speak with your doctor or pharmacist.
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.

The link between chronic disease and ED is most striking for diabetes. Men who have diabetes are two to three times more likely to have erectile dysfunction than men who do not have diabetes. Among men with erectile dysfunction, those with diabetes may experience the problem as much as 10 to 15 years earlier than men without diabetes. Yet evidence shows that good blood sugar control can minimize this risk. Other conditions that may cause ED include cardiovascular disease, atherosclerosis (hardening of the arteries), kidney disease, and multiple sclerosis. These illnesses can impair blood flow or nerve impulses throughout the body.
Surgery for erectile dysfunction is usually considered only after all other options have failed. The two surgical options include the insertion of a semi-rigid rod or the implantation of a three-piece inflatable prosthesis. Penile prosthesis implantation has low infection, complication, and malfunction rates. However, since placement of an implant requires permanent injury to the erectile tissue of the penis, implant treatment is considered irreversible.
Where alcohol may succeed as an aphrodisiac in getting people “in the mood” it may fail in execution. During an erection, the penis fills with blood then the vessels close, preventing backflow, so that the penis remains erect. In the short term, overconsumption of alcohol causes the blood vessels in the penis to expand, allowing for more blood flow, but prevents those vessels from closing. As a result, the penis may become erect but not remain so, as there is nothing to prevent backflow.
ED usually has something physical behind it, particularly in older men. But psychological factors can be a factor in many cases of ED. Experts say stress, depression, poor self-esteem, and performance anxiety can short-circuit the process that leads to an erection. These factors can also make the problem worse in men whose ED stems from something physical.

If the patient reports that PDE 5 inhibitors work poorly or inconsistently, we offer CIS to objectively assess erectile function and to provide diagnostic information. For the CIS, inject bimix (such as papaverine 30 mg/phentolamine 0.5 mg/mL—0.2–0.3 cc) and have the patient compress the injection site for 5 minutes. After 5 minutes, instruct the patient to self-stimulate, then assess his response to injection. One could also combine penile color duplex ultrasound (PCDU) with the CIS. However, PCDU is expensive, may not be covered by the patient’s insurance, and may require increased dosages of pharmacologic agents, such as trimix (papaverine 30 mg/phentolamine 0.5 mg/alprostadil 10 mg–0.5 cc) to obtain complete smooth muscle relaxation. This often requires reversal of erection using phenylephrine after the study. In rare patients who failed to achieve and maintain erection with 0.5 mL of trimix, we may proceed with pharmacologic cavernosography or pharmacologic arteriography depending on the results of PCDU.

"Smoking is a short- and long-term cause of erectile dysfunction," warns Feloney. "In the short-term nicotine constricts the blood vessels that you need to get an erection, and in the long-term nicotine contributes to hardening of the arteries that can cause erectile dysfunction." Some approaches for quitting include making a clean break, avoiding the triggers of smoking, trying a nicotine patch or gum, and joining a smoke cessation program.
"We used to think that ED in young men was 90 percent psychological, but we now know that most cases are caused by a combination of risk factors. Erectile function depends on hormones, blood supply, nerve function, and psychological health,” said Run Wang, MD, professor of urology at The University of Texas Health Science Center in Houston and director of sexual medicine at MD Anderson Cancer Center.

ED can also occur among younger men. A 2013 study found that one in four men seeking their first treatment for ED were under the age of 40. The researchers found a stronger correlation between smoking and illicit drug use and ED in men under 40 than among older men. That suggests that lifestyle choices may be a main contributing factor for ED in younger men.
Premature ejaculation was reported by 36 out of 96 (37.5%) subjects, out of which, 27 (28.12%) had complaints of ejaculating within the first minute itself and the rest (9.38%) ejaculated within three minutes of intromission. The next most frequent sexual dysfunction reported was low sexual desire, which was reported by 36 out of 100 subjects. Erectile dysfunction was reported by 33.3% of the subjects with difficulty in achieving erection in 19 subjects (19.79%) and difficulty in maintaining erection in 13 subjects (13.54%).
There have been rare reports of priapism (prolonged and painful erections lasting more than six hours) with the use of PDE5 inhibitors such as sildenafil, vardenafil, and tadalafil. Patients with blood cell diseases such as sickle cell anemia, leukemia, and multiple myeloma have higher than normal risks of developing priapism. Untreated priapism can cause injury to the penis and lead to permanent impotence. Therefore, if your erection lasts four hours, you should seek emergency medical care.
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.
While erectile dysfunction can occur at any age, the risk of developing erectile dysfunction increases with age. According to the Massachusetts Male Aging Study, the prevalence of erectile dysfunction was 52% in men 40-70 years of age. The prevalence of complete erectile dysfunction increases from 5% at 40 years of age to 15% among men 70 years of age and older.
Erectile dysfunction is more common than most people think. About 40% of men will notice some degree of problem by age 40. The aging of the penis can begin as early as the late 20s but becomes severe enough to notice typically starting in the 40s. As men get older, their odds of getting erectile dysfunction increases by about 10% per decade, and the severity of the problem also increases.
Most men may not openly talk about their erection problems, but erectile dysfunction — when a man cannot achieve or maintain an erection well enough or long enough to have satisfying sex — is very common. According to the National Institutes of Health, 5 percent of 40-year-olds and 15 to 25 percent of 65-years old have ED. But while ED is more likely to occur as a man gets older, it doesn’t come automatically with age.
Penile Injection Medication: This is just what it sounds like. Injected at home directly into the penis, the medication alprostadil produces erection by relaxing certain muscles, increasing blood flow into the penis and restricting outflow. Although some sources report an 80 percent success rate, the therapy has disadvantages, such as risks of infection, pain, and scarring—fibrosis—in the penis, and it may also cause priapism. A popular version of this medication is Upjohn Corporation’s Caverject. The MUSE System, by VIVUS, involves the same medicine (a pellet of alprostadil) applied with an eye-dropper-like applicator, directly into the urethra.
