Sildenafil has been on the market for more than 8 years. Morales and colleagues (1998) provided summarized safety until 1998 and Padma-Nathan and colleagues (2002) provided long-term safety data (>4 years). The most commonly reported treatment-related adverse events are headache, facial flushing, dyspepsia, dizziness, nasal congestion, abnormal vision, and palpitation (Table ​(Table2).2). Other adverse events uncommonly or rarely reported include back pain, influenza-like syndrome, rash, vomiting, diarrhea, cardiac arrhythmia, and hypersensitivity reactions. Adverse events are dose related, mild in nature, self-limited by continuous use. The drop-out rate due to adverse events is similar to placebo (2% for sildenafil vs 2.3% for placebo). Post-marketing case series reported higher incidence of adverse events, especially for headache (9%–39%), flushing (7%–33%) and abnormal vision (5%–11%) (Zippe et al 1998; Jarow et al 1999; Marks et al 1999; McMahon et al 2000; Moreira et al 2000; Fagelman et al 2001; Guay et al 2001; Martinez-Jabaloyas et al 2001; Palumbo et al 2001). Patients may tolerate sildenafil differently based on existing comorbidities. Ischemic heart disease and hypertension are associated with higher incidence of adverse events than diabetes (3.6%, 2.3%, and 1.9%, respectively) (Padma-Nathan et al 2002). Visual disturbances (blurred vision, flashing lights, blue haze, and change in color perception) occur due to weak inhibition of PDE6 in the retina. They are coincident with peak plasma concentrations of sildenafil and are transient and fully reversible. None persisted 6 hours after taking sildenafil and rarely consist a reason to discontinue treatment.
In a recent study, moderate-intensity exercise such as walking briskly and light cycling was shown to boost mood for up to 12 hours. Exercising every day might be best to lift your mood, but strive for at least 5 days a week. Another study showed exercise can improve your body image, regardless of body weight or shape. And feeling good about your body is a great start toward making the bedroom a happier place.
Surgery for erectile dysfunction is usually considered only after all other options have failed. The two surgical options include the insertion of a semi-rigid rod or the implantation of a three-piece inflatable prosthesis. Penile prosthesis implantation has low infection, complication, and malfunction rates. However, since placement of an implant requires permanent injury to the erectile tissue of the penis, implant treatment is considered irreversible.
We studied the involvement of zinc in the sexual behavioral response of male rats. The study design employed a rat model to predict the human sexual response to elemental zinc supplementation. Rats were used because they are very social and copulate under a variety of circumstances, regardless of the presence of a human experimenter. They are practical (small and easy to handle) and certain tissues and neuroendocrine systems are strikingly similar to humans.[13]
Adequate daily magnesium intake is slightly lower for younger men than for those in their 30s and older. The University of Maryland Medical Center recommends 400 mg daily for men between the ages of 19 and 30, and 420 mg per day for men 31 and older. While these levels are a good general guideline, you should check with your doctor to determine the proper dosage for a daily magnesium supplement, particularly if you’re using magnesium to help treat or prevent erectile problems.
Pay attention to your vascular health. High blood pressure, high blood sugar, high cholesterol, and high triglycerides can all damage arteries in the heart (causing heart attack), in the brain (causing stroke), and leading to the penis (causing ED). An expanding waistline also contributes. Check with your doctor to find out whether your vascular system — and thus your heart, brain, and penis — is in good shape or needs a tune-up through lifestyle changes and, if necessary, medications.
What if we look at erectile dysfunction as something that can be addressed as a condition other than a “pill for every ill”.   What if we actually look at a nutrient level that directly correlates to a medical condition and follow the science to give a directive on its recommendation?  Well it turns out taking a simple zinc supplement won’t help 100% of the time, but it certainly helps some of the time.

Overall health. Certain existing conditions can affect how long Viagra lasts and how well it works for you. Diabetes, nervous system conditions like multiple sclerosis (MS), and heart conditions like atherosclerosis (fat buildup in your blood vessels) can all make Viagra less effective and not last as long. Some kidney conditions may make Viagra last longer because of the condition’s effect on your metabolism.
There are so many potential reasons a man might develop erectile dysfunction (ED), it's nearly impossible to generalize the best ways to treat it. What works for one man may not work for another simply because they are having problems for different reasons. That said, it may encouraging to hear that there are a variety of options that may be considered, from psychological counseling to lifestyle changes, medications to treatments and devices.
Health benefits and risks of copper Copper is an essential trace mineral that occurs in all body tissues. It is vital for a range of body functions including the production of red blood cells and energy, and the maintenance of nerve cells and the immune system. A copper deficiency can be harmful, but too much can be toxic. Learn more about copper here. Read now
Erection is a complex physiological process in which vascular factors play a pre-eminent role. Therapeutic options for men with arteriogenic erectile dysfunction (ED) are mainly administration of phosphodiesterase type 5 inhibitors, intracavernous injections of vasoactive agents (for example, prostaglandin El, papaverine/phentolamine, or triple drug), intraurethral administration of prostaglandin El, and administration of centrally acting drugs (11, 12). However, all of these methods circumvent the patient's problem temporarily, and patients are not cured of impotence, they will remain dependent on these treatments for the remainder of their sexually active lives. An effective treatment that cures the problem permanently is needed where penile revascularization and exercise remain treatment options for such patients. However, due to the complexity of penile revascularization such as cost ineffectiveness, unavailability of experts, side effects of surgery and high failure rates among the elderly (13) have left people with ED at the mercy of exercise.
Many factors can contribute to sexual dysfunction in older men, including physical and psychological conditions, comorbidities and the medications used to treat them. Aspects of an ageing man’s lifestyle and behaviour and androgen deficiency, most often decreasing testosterone levels, may affect sexual function as well. A study of men between the ages of 30 and 79 years showed that 24% had testosterone levels below 300 ng/dL and 5.6% had symptomatic androgen deficiency.2
This African tree bark extract sends blood flow to the genitals, said herbalist Ed Smith, a founding member of the American Herbalists Guild, who adds a warning that Yohimbe can cause nervousness and raise already-existing high blood pressure (so avoid taking it if you have heart or kidney disease), and can also negatively interact with antidepressants.

The human body only contains 2 or 3 grams of zinc at any given time. Zinc is distributed throughout the body in organs, blood, and bones. It can be difficult to diagnose zinc deficiency. While a low blood zinc level does indicate a deficiency, a normal blood level does not necessarily indicate the absence of a deficiency. And examination of the hair for zinc or a zinc taste test (ZTT) may also be used for supportive evidence in the diagnosis of zinc deficiency.
In male rats, main olfactory epithelium (MOE) exerts an important role in regulating sexual behavior. Intranasal irrigation with zinc sulphate has been reported to destroy the MOE and completely abolish the sex behavior.[6] In this study supplementation of zinc was done using a feeding tube and precautions were taken to avoid contacting nasal area. Hence the possibility of reducing sexual performance due to MOE disturbance is ruled out. Some humans experience gastrointestinal irritation with supplementation of zinc.[23] If the same is applicable to animals it may be another possible explanation for the reduction of libido index with elevated doses of zinc. One drawback of our study is that we did not compare the weight of animals before and after treatment.
The truth is medication or psychosexual counselling are the first treatments a doctor will suggest because they’ve been proven to work. If a doctor has approved a medication for you then it’s safe. If you would still like to see if herbal supplements work for you, then there is a list below of supplements thought to work for erectile dysfunction. Just before you invest your money in them, remember they aren’t proven to work:

However, Viagra and other medications commonly have side effects. UK chemist chain Lloyds Pharmacy reports that as many as one in ten men will suffer nausea and/or headache, and between one in ten and one in a hundred may have a stuffy nose, indigestion, red rashes on the face, blurred or blue-tinted vision, and dizziness. While the risk is described as rare, or very rare, it can also lead to a stroke or heart attack.

For the study, data was collected from more than 800 randomly selected Australian men, 35 to 80 years old at the beginning of the study, with follow-up five years later. Sexual desire was assessed using a standard questionnaire that addressed interest in engaging with another person in sexual activity, interest in engaging in sexual behavior by oneself, and no interest in sexual intimacy.
