Table 3 is a suggested algorithm for the assessment of patients and their further categorization and handling. There are parts of investigation that are common for patients both with and without CVD, while additional elements of investigation are helpful in categorizing the patient without CVD to the appropriate risk category. Determination of exercise ability and stress testing is crucial to the assessment (see also below ‘Exercise ability: the risk of sexual activity’). Patients without established CVD or diabetes should be evaluated for their risk of future events according to risk scores (SCORE or Framingham). Patients with established CVD or diabetes are by default considered at increased risk. Patients with adequate exercise ability or a negative stress test can initiate or resume sexual activity and begin treatment for ED. In patients with a positive stress test or in high-risk patients, sexual activity should be deferred until the cardiac condition has been treated and stabilized. In all cases, patient follow-up and reassessment is recommended.
Joel Fuhrman, M.D. is a board-certified family physician, six-time New York Times bestselling author and internationally recognized expert on nutrition and natural healing, who specializes in preventing and reversing disease through nutritional methods. Dr. Fuhrman coined the term “Nutritarian” to describe his longevity-promoting, nutrient dense, plant-rich eating style.
A cold slice of watermelon can do more than just satisfy thirst and hunger during the warm summer months; it can help with bedroom satisfaction. Citrulline, the amino acid found in high concentrations of watermelon, is found to improve blood flow to the penis. A 2011 study revealed men who suffered from mild to moderate ED and took L-citrulline supplementation showed an improvement with their erectile function and were very satisfied. Natural watermelon juice, or “nature’s Viagra,” can also be easier on the stomach, since taking pills like Viagra can cause nausea and diarrhea.

Hypertension can affect endothelial function in many ways. It can reduce endothelium-dependent vasodilatation by increasing the vasoconstrictor tone as a result of increased peripheral sympathetic activity.41–43 Another mechanism is hypertension-induced increase in cyclooxygenase activity that leads to an increase in reactive oxygen species; these in turn damage endothelial cells and disrupt their function.44–46 In some cases, endothelial NO synthase (eNOS) gene variations may relate to hypertension-associated endothelial dysfunction.6
If the cause is believed to be organic but not hormonal, or if the patient defers psychological intervention, he can be offered the VCD or oral drug therapy. EDDM patients on organic nitrates or who have experienced or are concerned about potential adverse reaction to PDE-5 inhibitors are suitable candidates for the VCD. The VCD induces functional rigidity in 75% of patients with diabetes with autonomic neuropathy. Some patients or their partners may reject or discontinue the use of the VCD because it induces an unnatural erection, causes bruising and numbness of the penis, and or inhibits antegrade ejaculation.8

But recently Brandon had some troubles keeping it up. At first, Kayla just thought it was her and that he needed some kind of a change to what they usually did, but later Brandon admitted that as of late, he just couldn’t seem to maintain an erection, and that it took way too much effort to go long. It wasn’t that he wasn’t aroused; his body just wasn’t keeping up.

Another oral treatment that has been used with very little success is yohimbine (Yocon, Yohimex). This is an alpha 2 adrenergic receptor blocker that increases cholinergic and decreases adrenergic tone. It stimulates the mid-brain and increases libido. Optimal results occur when used in men with psychogenic ED. Side effects include anxiety and insomnia.
The safety of PDE5 inhibitors in patients with IHD has been shown in multiple trials. Arruda-Olson et al. investigated the safety of sildenafil during exercise stress tests in patients with IHD to ascertain whether the drug induces or exacerbates myocardial ischaemia. This was a prospective, randomised crossover study that demonstrated safety of sildenafil when given 1 hour before an exercise stress test.69 Another study that investigated 120 trials of sildenafil revealed that the rates of MI and cardiovascular death with sildenafil are as low as with placebo.70
A similar situation develops in the fragile penile circulation. Any disturbance in nitric oxide production lowers the capacity to dilate penile arteries, impairing penile engorgement for erection. Release of nitric oxide is readily sabotaged by many conditions, including elevated levels of cholesterol, high blood pressure, increased triglycerides, smoking, metabolic syndrome and diabetes, and excessive consumption of dietary saturated fat.9 If an artery’s inner wall can’t produce nitric oxide, an abnormal constriction of the arteries to the penis follows, effectively choking off blood flow.
If not properly controlled, both type 1 and type 2 diabetes can cause complications due to high blood sugar levels. Over time, these high levels can cause irreversible nerve damage and narrow your blood vessels. While nerve damage may affect the sensitivity of your penis, blood vessel damage can affect the blood flow to your penis and make it more difficult for you to get an erection.

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.
