During an erection, blood flows quickly into the penis, which increases its length, width, and firmness. If the "in" vessels (arteries) are too narrow or if blood drains too quickly through the "out" vessels (veins), men may have trouble achieving or maintaining an erection, says Arnold Aigen, MD, a urologist with Camino Medical Group in Sunnyvale, Calif. Viagra, which increases inflow, may not be strong enough to work its magic if the arteries are too narrow.
A review of 46 articles on phosphodiesterase type 5 inhibitor abuse was published in the journal Current Drug Abuse Reviews in 2011. One reason cited for abuse was easy access to ED drugs. A search for Internet drug stores found over six million hits at 7,000 Internet pharmacies. Only 4 percent of the sites were in proper compliance, according to the Verified Internet Pharmacy Practice Sites program.
The penis contains two chambers, called the corpora cavernosa, which run the length of the organ. Erection begins with sensory and mental stimulation. Impulses from the brain and local nerves cause the muscles of the corpora cavernosa to relax, allowing blood to flow in and fill the chambers. The inflow of blood creates pressure in the corpora cavernosa chambers, making the penis expand. Erection is reversed when muscles in the penis contract, stopping the inflow of blood and causing the blood in the chambers to flow out.

Poor sleep patterns can be a contributing factor for erectile dysfunction, Mucher says. One review published in the journal Brain Research emphasized the intricate relationship between the level of sex hormones like testosterone, sexual function, and sleep, noting that testosterone levels increase with improved sleep, and lower levels are associated with sexual dysfunction. Hormone secretion is controlled by the body’s internal clock, and sleep patterns likely help the body determine when to release certain hormones. 

Thank you for posting this. The exact same thing happened to me, My Dr. recommended Niacin to reduce LDL and increase HDL. Trouble is I noticed my sex life really dropped quickly. Very rare to get and maintain an erection. I couldn't quite tell but it seemed to me the problems started a couple of weeks after I began the Niacin. Out of desperation I quit Niacin to see what would happen and suddenly the full and regular erectiions came back. Everything I read says the effect should be the opposite. Now I have to decide do a die earlier of heart disease and have more sex or better cholesterol control with a diminished and almost non-existent sex life. Pretty sure I'm gonna favor the sex life!

Combination therapy has proven effective for some men who don’t respond adequately to oral medicines. The idea is to use two drugs with different mechanisms of action for better results. Commonly, sildenafil is used in combination with pellets of alprostadil (synthetic prostaglandin E1) that are inserted into the urethra (the tube in the penis that carries urine from the bladder to the outside of the body). Alprostadil also increases the blood supply to the penis, but by different means.

Erectile dysfunction is a self-reported condition by the patients and the results of different treatment modalities are also self-evaluated (Hatzimouratidis and Hatzichristou 2005). Recent data on ED treatment outcome have shown that many patients discontinue treatment, despite the availability of efficacious pharmacotherapies, because doctors fail to inform patients properly and to ensure continuity in care, as well as to be routinely involved in asking patients about their needs and expectations (Mulhall et al 1999; Hatzichristou et al 2005). Althof (2002) described several causes that may contribute, including the length of time the couple were asexual before seeking treatment, the man’s approach to resuming a sexual life with his partner, the female partner’s physical and emotional readiness to resume lovemaking, the meaning for each partner of using a medical intervention to enable intercourse and the quality of the nonsexual aspects of the relationship. It becomes apparent that patients’ needs and expectations vary widely and the treatment approach should always be individualized according to their preference for information and involvement in the decision-making process. Patient satisfaction is a complex issue that depends not only on therapeutic outcomes in terms of efficacy and adverse events or complications but also on expectations from treatment and relationship dynamics.

While balancing your sexual focus is singularly the most important aspect of solving a sexual dysfunction challenge, it's important to also address the physical component. This is especially true if you are over 40, or suffer from erectile dysfunction. Exercise increases blood flow and helps your body eliminate toxins. As well as this, exercise also improves your strength, stamina and form.

Psychological factors can make a big difference with regard to treatment and outcome, and should not be underestimated (the placebo effect is a good example). Brand, size, shape, and colour of a pill can all have a psychological impact on a patient’s confidence in the treatment. There is also documented evidence that a higher dosage can have a positive psychological effect, however side effects are more likely. Studies also suggest men’s mood improves after taking sildenafil.
The substance that gives hot peppers their kick can also give you some kick in the pants: Studies have associated the natural chemical with increased testosterone levels. In animal studies, capsaicin has also shown to increase the size of sex organs, while simultaneously decreasing belly fat. A 2014 study from France also found that men who ate more spicy food had higher testosterone levels than those who ate less. You can consume capsaicin via peppers, chili powder or a cayenne supplement.

April 10, 2000 (Mill Valley, Calif.) -- In his early 40s, Ron Hanson was too young to be having trouble getting and sustaining erections. But like many men, he was too embarrassed at first to talk about the problem. Hanson (not his real name) waited seven years to see a urologist. By the time he spoke up, erectile dysfunction had become a household word, thanks to the popularity of the drug Viagra. But the widely touted drug, Hanson soon learned, doesn't work for everyone.


Research is mixed on the effectiveness of acupuncture as an erectile dysfunction cure, but one study published in November 2013 in the Journal of Alternative and Complementary Medicine found that acupuncture can be beneficial for men experiencing erectile dysfunction as a side effect of antidepressants, including selective serotonin reuptake inhibitors (SSRIs) and serotonin noradrenaline reuptake inhibitors (SNRIs).
