Some blood pressure medicines can also cause erectile dysfunction. Thiazide diuretics and beta-blockers are most likely to cause problems, but this is not a common effect of these medicines and will not happen to everyone. If you are taking either of these medicines and are worried about erectile dysfunction, your GP may be able to change your medicines.

Consider this:  penicillin, the first successful antibiotic, was derived from molds that inhibit bacterial growth.  Scientists had to figure out why the molds slowed bacteria, and refine the active ingredients.  Using herbal supplements is somewhat like putting mold on a wound.  It might help, a little, but it’s certainly not going to help as much as using penicillin.
Obesity is a strong predictor of ED as it is associated with other risk factors, such as diabetes, hyperlipidaemia and hypertension.4 Obesity increases the risk of ED by 30–90 % and acts as an independent risk factor for CVD. Obese men with ED have greater impairment in endothelial function than non-obese men with ED.5 Moreover, high BMI causes low testosterone levels, which in turn leads to ED, as observed in a prospective trial involving 7,446 participants.50
 Other treatment options such as penile self-injection therapy, external vacuum pumps and the medicated urethral system for erection are on rare occasions an effective long-term treatment. A very small percentage of men will continue with these treatments as evidenced by a very high drop out rate and a very low refill rate for these treatments. These procedures require extensive planning which interfere with sexual spontaneity and are really not a realistic long-term treatment for young patients with permanent ED. 
Characteristics that imply a higher risk is severe ED (SHIM 1–7) and ED duration >3 years.15,30 Vascular and circulating biomarkers may help to characterize further the patient with ED.23 Of the wide array of biomarkers that have been proposed for the assessment of cardiovascular risk in asymptomatic adults,34,35 some have been studied specifically in the context of ED.23Table 4 offers a critical evaluation of these biomarkers. Such tests should be considered as potentially helpful and thus recommended where available, but not mandatory.30 Despite its potent predictive ability recently shown,36 exposure to radiation with coronary artery calcium scoring should be carefully weighed. Although not specific for ED, it might be reasonable to evaluate biomarkers that have been proposed for the intermediate-risk patient such as uric acid, glycated haemoglobin, microalbuminuria, and lipoprotein-associated phospholipase A2.30
The obvious risks are the same that accompany any surgery: infection, pain, bleeding, and scarring. If for some reason the prosthesis or parts become damaged or dislocated, surgical removal may be necessary. With a general success rate of about 90 percent, any of the devices will restore erections, but they will not affect sexual desire, ejaculation, or orgasm.
“If a diabetic patient has erectile dysfunction, it’s not enough to provide Viagra [sildenafil] or Cialis [tadalafil] and then send him on his merry way,” J. Francois Eid, MD, a New York City urologist, said at the annual meeting of the American Association of Diabetes Educators. “It’s important to let individuals know the drug has not cured the erectile dysfunction. If patients don’t take care of the diabetes, the erectile dysfunction progresses.”

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:
The links between hypertension and ED are increasingly recognized and the 2009 re-appraisal of European guidelines includes relevant statements.35,47 Erectile dysfunction is almost twice as frequent in hypertensive as in normotensive individuals and appears to be of higher severity. The relative risk of developing ED in hypertensive patients compared with normotensive individuals ranges from 1.3 to 6.9. Regarding pathophysiology, hypertension appears to cause ED per se, through a multitude of mechanisms that include prolonged exposure to elevated levels of systemic blood pressure, endothelial dysfunction, and circulation of vasoactive substance (with a pivotal role of angiotensin II) that lead to structural and functional alterations in the penile arteries. The largely unfounded (see earlier paragraph) notoriety of antihypertensive treatment for causing ED is one of the most predominant causes for non-adherence and discontinuation of antihypertensive therapy, and therefore, patients should be properly informed by physicians. Phosphodiesterase type 5 inhibitors are effective in hypertensive patients with ED and they can safely be co-administered with antihypertensive medication.39 Specifically for alpha-blockers, low starting doses of PDE5 inhibitors are preferred in patients already on alpha-blocker treatment, and likewise, low starting doses of alpha-blockers are encouraged in patients taking PDE5 inhibitors. Of clinical significance is that hypertensive men with ED are more likely to comply with their antihypertensive medication when under PDE5 inhibitors.

A study published in May 2014 in The Journal of Sexual Medicine found that some men can reverse erectile dysfunction with healthy lifestyle changes, such as exercise, weight loss, a varied diet, and good sleep. The Australian researchers also showed that even if erectile dysfunction medication is required, it's likely to be more effective if you implement these healthy lifestyle changes.
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.
