Alprostadil self-injection. With this method, you use a fine needle to inject alprostadil (Caverject Impulse, Edex) into the base or side of your penis. In some cases, medications generally used for other conditions are used for penile injections on their own or in combination. Examples include papaverine, alprostadil and phentolamine. Often these combination medications are known as bimix (if two medications are included) or trimix (if three are included).
When given orally, yohimbine reaches peak levels in 10–15 min, and the half-life is 0.6 h. The efficacy of yohimbine in sexual function has been questioned, perhaps because of early questionable multidrug preparations.10,11 Yohimbine has been shown to have some effect on psychologic erectile dysfunction12,13 and in reversing fluoxetine-induced sexual dysfunction.14
Clinical trials were included if they met all of the following inclusion criteria: study population defined; Men with arteriogenic ED were considered; the present review was concerned with studies that used aerobic exercise on ED; only randomized controlled trials on this topic were selected for review; The main outcome measure was satisfactory intercourse without additional therapy using the International Index of Erectile Dysfunction (IIED) scores. The present review utilized studies that had successfully undergone rigorous peer review (i.e., published peerreviewed journals), were included.
1. Increased Blood Flow in Men with Lower Niacin Levels. Of course, there is a lot to an erection, but I think just about everyone would agree that the #1 goal is to increase something called endothelial function. The endothelium is the delicate lining of the arteries that pumps out nitric oxide and relaxes the arteries. And, of course, a relaxed, i.e. more open artery is one that allows more blood to flow into your arm, your leg or your brain. And I'm sure I don't need to explain why increased blood flow into your penile arteries is critical for erectile strength.
Hypercholesterolemia (high cholesterol) is one of the main risk factors in the development of atherosclerosis, a condition that with the development of statins over the last 20 years has become more treatable, but not without consequences. Statins have been shown to reduce the incidence of cardiovascular events by 25–40%, yet this reduction is no big deal, especially considering that many patients need additional therapy to reach more optimal lipid levels and prevent cardiovascular events.
Vitamin B6 deficiency leads to irritability, numbness in the extremities, muscle weakness, fatigue, drowsiness, impaired mental activity, peripheral neuritis, seborrheic dermatitis, stomatitis, conjunctivitis, and, of course, impairment of sexual potency. Lack of this vitamin can be a result of long-term use of anti-tuberculosis drugs and chronic diseases of the gastrointestinal tract.
Despite the name, horny goat weed actually helps improve your erection, not libido. Botanically known as epimedium, this herb has been used by the Chinese for centuries to treat, among other things, low libido and erectile dysfunction. “A growing body of research shows that isolated icariin—the extract of epimedium—inhibits the enzyme phosphodiesterase-5 (PDE-5) and significantly increases nitric oxide synthase, helping to improve erectile function,” says Fisch. In fact, this is the same mechanism that Viagra works through (but the herb comes with a way better name).
A study from 1990 (eight years before Viagra was introduced) found that sedentary but otherwise healthy middle-aged men who started an intense aerobic exercise program reported higher levels of sexual intimacy, and more reliable sexual function. Men in the study who started a walking program also experienced improvements, though not as dramatic. But the bottom line is, improved physical fitness often improves sexual functioning and satisfaction. Here are 5 exercises that can help with erectile dysfunction.
On the other hand, high zinc levels have negative effects on sperm quality. Excessive zinc intake in mice have indicated a negative effect of increasing doses of zinc on sperm count and motility. Although there have been studies focusing on various aspects of zinc related reproductive functions, studies on zinc related sexual behavioral aspects have received scant attention. In one study, intranasal irrigation with zinc sulphate has been reported to completely abolish the sexual behavior of male rats.
Clinically I have seen these results in doses of just 20 mg twice daily. It is important to note that prolonged zinc supplementation can lead to lowered copper levels so it is not advisable to continue this therapy unless it is in a cyclical nature. For those on long term zinc there are combination products with Zinc and Copper. In cases where some prescriptions that lower zinc are given, like acid lowering meds, thiazide diuretics and ACE inhibitors, or in renal dialysis patients, this chronic monitoring of zinc may lead to longer term supplementation.
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!
a) Some Vegetarians and Vegans. It should be pointed out that certain animal-based foods are known for being the highest providers of niacin. So does this mean that animal-emphasized diets will result in increased blood flow over vegetarians? My experience on the Peak Testosterone Forum has been the opposite and this is the subject of my book The Peak Erectile Strength Diet. Basically, a great many plant foods directly stimulate nitric oxide and will increase blood flow while lowering blood pressure. In fact, some plant foods can lower blood pressure as much as modern hypertension medications. See my page on Flaxseed and Blood Pressure for an example of that. High nitrate foods, such as spinach, arugula and beets, are yet another example.
So what causes erectile dysfunction? Sometimes it is a circulation problem. Sometimes it is a low testosterone issue. Sometimes it is not. Testosterone (T) supplementation can help ED and low libido in cases of low T and even if there is a normal T level at baseline, ED can be helped. In cases where thyroid under or overactivity is causing T levels to be less than optimal. Aging is also a problem as T levels drop after mid 20’s and as adipose tissue increases and aromatase enzyme conversion of T to Estrogen correspondingly increases. This causes an unfavorable E:T ratio which equates to low T.
Unfortunately, many of the same factors that brought the Italian Renaissance to an end—among them corruption, wars, and a widespread backlash over secularism and indulgence (leading to the “Bonfire of the Vanities”)—also terminated the “rebirth” in Spain. Chasing heresies became a sport that led to the resurrection of the Inquisition, which unlike its prior appearances operated completely under royal authority, rather than the aegis of the church.
Zinc distributes all over the body, so it’s difficult to test through a blood test. If you have problems with erectile dysfunction or suspect that you might have a zinc deficiency, talk with your doctor. A medical professional will be able to check your testosterone level and determine if using zinc supplements to treat your ED is an appropriate course of action.
