High blood pressure can damage blood vessels, and this damage may lead to cardiovascular disease – the leading cause of erectile dysfunction.
“There is a strong, emotional, psychological component,” Berglund said, “to being able to get an erection — quote-unquote ‘being in the mood.’” .
Peyronie's disease is a condition that results from a penis injury, causing scar tissue to form and the shaft to curve. Sexual intercourse is often difficult.
While ED medication works for most patients, there are other treatment options. These include external vacuum devices that draw blood into the penis and injections that men administer themselves to dilate the arteries of the penis and allow blood to flow in. Another option is penile implants, which Dr. Walker calls the “gold standard” for men who cannot tolerate the drugs and for whom other treatments fail. Flexible cylinders are embedded in the penis. The man pumps fluid into them from a reservoir when he wants to perform sexually.
Dr. Ira Sharlip, a clinical professor of urology at the University of California at San Francisco and spokesman for American Urological Assn., says that the results are intriguing but further studies need to be done on sexual intercourse and erectile dysfunction before the link becomes clear. Other factors could partially explain the findings, he notes, such as inborn powers. “Maybe some people are wired to be more sexual and also to have better erections for a longer period of time,” he says.
Usually, having spontaneous erections at night or in the morning is a good indicator of testosterone status. It means you have enough testosterone in your blood to rule out a severe deficiency. It would also help your doctor rule out other physical causes of impotence.
An association means that there is a statistical relationship between two variables. For example, when A increases, B increases. An association means that the two variables change together, but it doesn't necessarily mean that A causes B. The relationship isn't necessarily causal.
Sildenafil (Viagra) may affect another phosphodiesterase enzyme in the eye causing transient abnormal vision (seeing a bluish hue or brightness).
Tadalafil (Cialis) has an effect on another phosphodiesterase enzyme, PDE11, which is located in muscle. Tadalafil is associated with muscle aches in some men.
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.
A number of medical conditions share a common problem with ED, such as the impaired ability of blood vessels to open and allow normal blood flow.
In addition, your doctor may address underlying conditions. They may suggest counseling or medication changes. They also may suggest lifestyle changes, including increased exercise or dietary changes. It is also a good idea to avoid drugs, alcohol, and cigarettes.

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.
Although extensive testing in animals has demonstrated no negative effects on the fetus, Viagra has not been studied in pregnant women. There is no effect on sperm count or motility of sperm in men.
There can also be drug-drug interactions with other medications you take, potentially including anti-HIV drugs. When taken with ritonavir or cobicistat (boosting agents included in some HIV treatment regimens), levels of the erectile dysfunction medication may be increased, potentially adding to side-effects. On the other hand, when taken with non-nucleoside reverse transcriptase inhibitors (NNRTIs), levels of the erectile dysfunction drug may be lowered.
Thomas said he recognizes that studies like these often become highly politicized and weaponized on news and social media feeds by people for and against the oilsands. He added that the industry listens to reputable science and has responded in proactive ways in the past when their practices have been shown to be harmful.
Horny goat weed is an herb that has been used in China for centuries to treat low libido, erectile dysfunction, fatigue, and other conditions. Learn how its extract may help increase blood flow to the penis.
