Another potential new treatment consists of penile low-intensity shock wave lithotripsy. This consists of 1500 shocks twice a week for 3–6 weeks. The purpose is to stimulate neovascularisation to the corporal bodies with improvement in penile blood flow and endothelial function. The use of low-intensity shock wave lithotripsy may convert PDE5 inhibitor non-responders to responders.47

Older age. A man’s risk increases past the age of 40, as age is the variable most strongly associated with impotence. This is due to changing hormones, higher risk for heart problems and those affecting circulation, and decreased sexual desire that often occurs with increasing age. For example, based on findings from the National Health and Social Life Survey, it’s been found that “men between 50–60 years old are more than 3 times as likely to experience erection problems and to report low sexual desire compared to men aged 18 to 29 years.” (3)


"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.


When Viagra (sildenafil) hit the market in 1998, some men thought it was the long-awaited answer to their problems. Many rushed to doctor's offices to give it a try. According to the Grey Clinic in Indianapolis, which specializes in erectile dysfunction, 17% of men between 18 and 55 experience occasional impotence, while 6% have regular erectile difficulties. For men over 55, that number jumps to about one in three. Some common causes of impotence are diabetes, heart disease, and psychological problems. It also frequently occurs after prostate cancer surgery.

Some studies have shown Levitra to be more suitable for men suffering from diabetes. Other treatments include Caverject ('Alprostadil'), which is a medication injected directly into the penis and MUSE (another form of 'Alprostadil'), which is a pellet inserted into the urethra. These may be of use for men who have to take Nitrates and are therefore unable to take the PDE5 inhibitors.
Risk factors for ED include older age, obesity, diabetes, heart disease, and high blood pressure. The problem is that men without issues are using these medications. "We are seeing more and more young men without any risk factors for ED asking for ED drugs. They look a lot like the young men dancing around in the TV advertisements, probably too healthy to have ED,” said Rowena DeSouza, MD, associate professor of surgery at the University of Texas Health Science Center at Houston and director of urology at Lyndon B. Johnson Hospital.
Many prostate problems, including cancer, are linked to zinc deficiency, and when the Chicago Center for the Study of Prostatic Diseases gave 50 to 100mg of zinc daily to patients suffering from infection of the prostate, 70 per cent of cases showed improvement. Zinc levels decline with age and men over fifty can fight impotency and prostate enlargement by taking zinc supplements.

Both patients and partners report higher levels of satisfaction (assessed with the Erectile Dysfunction Inventory of Treatment Satisfaction [EDITS] questionnaire) after sildenafil treatment relative to placebo (Lewis et al 2001). Patients receiving sildenafil had significantly higher scores (73.6 ± 3.2) than did those receiving placebo (48.4 ± 3.2, p<0.001). The scores on the partner version of the EDITS were also significantly higher among the partners of men who received sildenafil (63.9 ± 8.1) than among the partners of those who received placebo (33.3 ± 7.5, p<0.001). A high level of treatment satisfaction (65%) reported in another clinical practice study (assessed by 5-item scale) (Jarow et al 1999). Treatment satisfaction was correlated with ED severity (41% in severe, 78% in moderate, and 100% in mild ED) and etiology (56% in neurologic causes, 58% in diabetes, 35% in radical prostatectomy, 89% in psychogenic causes, and 86% in vasculogenic causes). However, no particular characteristic predicted absolute failure with sildenafil. Sildenafil also improved all aspects of health-related quality of life (assessed by SF-36 or Q13 and Q14 of the IIEF) in general ED population or subgroups such as spinal cord injuries (Hultling et al 2000; Giuliano et al 2001; Fujisawa et al 2002). Significant improvements in self-esteem, confidence, sexual relationship satisfaction, and overall relationship satisfaction after treatment of ED with sildenafil were reported by Althof and colleagues (2006) using the self-esteem and relationship questionnaire (SEAR) in a cross-cultural double-blind, placebo controlled, flexible dose study (Althof et al 2006; Cappelleri et al 2006). Treatment satisfaction is also maintained through time (Figure ​(Figure3)3) (Carson et al 2002).


The nitric oxide stimulates an enzyme that produces something called a messenger cyclic guanosine monophosphate (cGMP). The cGMP relaxes the smooth muscle cells. One result of this is that the arteries in your penis dilate and the blood can flow into your penis more easily. Another result is that the erectile tissue itself fills with blood. Both of these process result in an erection. Viagra works by maintaining the level of cGMP in the smooth muscle cells.
Take note that you may not be able to complete a series of about 10 kegel exercises on your first try. This is just fine. Just do what you can, and gradually work on more kegel exercises until you reach 10 to 20 kegels, up to three times in a day. When performing these exercises, avoid holding your breath, or pushing your stomach, thigh muscles, or buttocks in. It would be helpful if you relax after every count of five. You may also challenge yourself by alternating between long and short squeezes.
A mineral involved in muscle development, muscle is essential for reproductive function in men of every age and activity level. One study that compared athletes to non-active individuals found that supplementing with 22 mg magnesium per pound of body weight of the course of four weeks raised testosterone levels in both groups. And two separate studies, one on a group of men over the age of 65 and a second on a younger 18-30-year-old cohort, present the same conclusion: levels of testosterone (and muscle strength) are directly correlated to the levels of magnesium in the body. These are the best foods for magnesium!
It is important to understand that ED is frequently, if not usually, directly related to endothelial dysfunction, and that the release of NO by the vasculature of the penile arteries is directly related to the function of intact, healthy endothelium. In the face of endothelial dysfunction, the process of erection fails to occur in a normal fashion.16
Vitamin D is primarily known to help bone health and for its role in calcium-phosphorous homeostasis—but a new study found it also improves erectile dysfunction. Men who received vitamin D supplements showed increased testosterone levels and improved erectile function, researchers reported. The trial included only 41 men, so a larger study is needed to confirm the results. But what mechanism might be behind vitamin D's erectile effect? Click here to find out.

How men can improve their sexual performance Many men want to know how to enhance their own and their partners’ sexual satisfaction. However, placing too much emphasis on performance can lead to anxiety. Certain lifestyle changes can help to reduce sexual anxiety, improve erectile dysfunction, and increase stamina. In this article, we describe 13 methods to try. Read now
The development of successful sexual behavior involves not only important neuroendocrine and local genital changes that begin at puberty, but also psychological and social influences that occur both before and after puberty.[7,8] Sexual behavior in males is regulated mainly by internal patterns of hormones; i.e. T, progesterone and PRL. These hormones are modulated by the male interactions with the social environment.[9]
Three subsets (eight in each subset) of sexually experienced adult male rats were supplemented with three different oral doses of zinc sulphate (a daily dose of 1 mg, 5 mg and 10 mg respectively) for two weeks. A subset of eight animals without zinc supplementation was used as the control group Sexual behavior was observed by placing them individually in cages with receptive females.

Sildenafil is a highly selective inhibitor of PDE type 5 (Boolell et al 1996; Gbekor et al 2002). It enhances NO-mediated relaxation of human corpus cavernosum in vitro (Ballard et al 1998; Stief et al 1998; Gemalmaz et al 2001). Sildenafil, by inhibiting phosphodiesterase, increases the intracellular concentrations of cyclic guanosine 3’,5’ monophosphate (cGMP), causing an amplification of the endogenous NO-cGMP signaling pathway.


L-arginine, an amino acid that is naturally present in the body and helps make nitric oxide, supports a successful erection. Nitric oxide is responsible for making the blood vessels relax, which helps sustain an erection for men. A 1999 study, observed the effects of six weeks of high-dose (5 grams/day) orally administered nitric oxide (NO) donor L-arginine on men with organic ED. Thirty-one percent of those who took 5 grams/day of L-arginine experienced significant improvements in sexual function. Burns told Medical Daily, “l-arginine and deer antler velvet” have been the most popular go-to natural treatments for men.
