It can be frustrating trying to determine why you aren’t experiencing the desired results but there is usually a reason, so consider the preceding factors and arm yourself with this knowledge as you speak with your GP. There are different things you can do to help bring about the results you’re hoping for, just remember that success with ED isn’t always instantaneous.
“One important danger that men need to know about if they are using ED drugs recreationally is drug dependence. Men who take the drugs for longer and larger erections may find that they actually develop ED without the drugs. This could mean having to use more aggressive treatments like injections or implants to treat ED in the future,” warned DeSouza.

"Erections are good for your penis, and probably good for mental health. Taking medication for erections may also be good for a man's overall health. This is the first study to look at long-term treatment to improve erectile function in men, but the sample is too small to definitively answer the question. We really need a big study with a long follow-up to know the answers." Mulhall, who was not involved in the study, is an associate professor and director of sexual medicine in the departments of urology at Weill Medical College of Cornell University and Memorial Sloan-Kettering Cancer Center in New York.


The number of animals ejaculating within 15 minutes was significantly reduced in 5 mg zinc treated group (one out of eight). However, all intromitted rats ejaculated between 20-30 minutes when observation was continued. Ejaculatory latency was significantly high in this group compared to controls; 711.60 Sec (SEM 85.47) vs. 489.50 Sec (SEM 67.66), P < 0.05. Similarly, they showed a significantly higher frequency of penile thrusting compared to controls; 26.50 (SEM 6.17) vs. 52.80 (SEM 11.28), P < 0.05 [Table 1].
The search criteria identified 210 studies from 1972 to 2010; on inserting randomized controlled trials only 26 studies were identified out of which only 5 met the inclusion criteria and 21 studies did not meet the inclusion criteria, hence, were excluded. Five (18, 24–27) randomized controlled trials (RCTs) met the inclusion criteria; studies involved the use of aerobic exercise in the management of ED, the IIEF was the assessment tool for ED and also involved control groups. A total of 385 subjects were involved: Lamina et al (25), n=43; Lamina et al (26), n=43; Esposito et al (18), n= 110; Kalka et al (27), n= 129; Maio, Saraed and Marchiori (24), n= 60.

Check to see if an online pharmacy is legitimate. Never order medications from an online pharmacy if there's no way to contact the pharmacy by phone, if prices seem too good to be true or if you're told no prescription is necessary. Some illegal businesses sell counterfeit versions of legitimate medications, which can be ineffective or dangerous. In the U.S., the National Association of Boards of Pharmacy can tell you whether an online pharmacy is licensed and in good standing.
The following parameters were computed using the observed behavioral measures. Copulatory efficiency (proportion of mounts resulting in vaginal penetration relative to the total number of mounts), intromission ratio (number of intromissions/number of intromissions + number of mounts) and intercopulatory intervals (average time between intromissions).[8]

Usually patients will try less invasive alternatives to treat impotence before opting for surgery. These alternatives may include supplements, herbs, lifestyle changes and even medications. In cases where other treatments do not work to resolve ED, surgery might be a last-resort option. Surgery involves implanting a penile prosthesis. This is a saline-filled silicone device or a malleable device. Although the likelihood of serious side effects is considered to be low, certain risks are associated with surgery to correct erectile dysfunction. These side effects may include: anesthetic risk, device infection, and device malfunction or mechanical failure. Some studies have found that five years following surgery around 10–20 percent of men experience device malfunction and failure. Infection rates are low. Around one percent of men who opt for this type of surgery get an infection.

If you have symptoms of ED, it’s important to check with your doctor before trying any treatments on your own. This is because ED can be a sign of other health problems. For instance, heart disease or high cholesterol could cause ED symptoms. With a diagnosis, your doctor could recommend a number of steps that would likely improve both your heart health and your ED. These steps include lowering your cholesterol, reducing your weight, or taking medications to unclog your blood vessels.
