An erection problem, or erectile dysfunction, is one of the commonest disorders of male sexuality. Penile blood flow depends on a complex interaction of psychological, neural, vascular and endocrine factors. Testosterone has an important role in both central and peripheral domains of this process. Neurotransmitters are also involved in starting and to maintain a better penis erection including dopamine and nitric oxide. Men who have difficulty with keep an erect penis seek an erection ring, pump, vacuum device, cream, or search for a pill such as Viagra or herbal erection pills. To maintain a strong penis, it is best to have a deep sleep at night, have low stress, eat a healthy diet with plenty of vegetables and fish, have a moderate amount of exercise, do yoga, meditation, or relaxation techniques, and have an open heart and close intimacy. All these steps can lead to a longer erection time in a man.

How an erection happens
A complex interaction of neural, vascular, and biomolecular activity results in normal erectile function. Two chambers in the penis, the corpus cavernosa, contain sinusoids, which fill with blood and expand to become rigid when smooth muscle is relaxed. Blood flow out of the penis is temporarily stopped (veno-occlusion). Neural control is complex but, in general, the sympathetic nervous system inhibits, and the parasympathetic system excites erection. The central nervous system can induce erections without peripheral stimuli, e.g. in nocturnal erections. In general, there are 5 recognized phases in the response: latent, tumescent, full, rigid, and detumescent. The key biochemical event in this function is an increase in levels of cyclic guanosine monophosphate, which causes smooth-muscle relaxation and allows an erection to occur. This process is mediated by nitric oxide, produced by neurons and elsewhere, which acts as a gaseous messenger molecule.

Passion Rx -- Medical Doctor formulated
Passion Rx provides an erection problem solution sometimes noticed within a day or two, but most often it takes several days for the full sexual enhancement to be appreciated. This male and female herbal formula contains a number of erection enhancing herbs including Mucuna Pruriens, tribulus terrestris extract, tongkat ali, muira puama, catuaba, yohimbe bark extract, horny goat weed sex enhancer, and others. A version of Passion Rx is available without yohimbe.
Dr. Sahelian and his research staff have tested various doses and extracts of dozens of herbs from a number or raw material suppliers to determine the ideal dosage and combination for optimal erection enhancement with the fewest side effects. After years of trial and error,  a unique proprietary blend with 15 herbal extracts from the best raw material suppliers has been created which works within hours.

Erection problem may indicate cardiovascular or heart problems
The arteries in the penis are about one-third the size of one of the coronary arteries supplying the heart. When smaller blood vessels, such as the penile arteries, are narrowed even a small amount, it can have a major effect on their capacity to dilate. When a man becomes aroused, the brain sends signals to the penis to release a chemical that rapidly widens blood vessels. Blood rushes in, causing an erection. Damage to those vessels can make them inflexible, limiting their ability to expand. This damage to the penile arteries and the subsequent erection problems may indicate that damage has occurred to other arteries in the body, including coronary arteries.

Several studies have shown that men with ED have a significantly higher risk of cardiovascular disease - heart attacks and strokes. In fact, many of the causes of ED are also risk factors for atherosclerosis; the condition in which fatty plaque builds up in blood vessels, causing restricted blood flow.

NO erection enhancer
Nitric oxide is a chemical in the bloodstream that helps dilate blood vessels, including those in the penis, thus any herbs or supplement that increases nitric oxide levels help to maintain and improve an erection.

Vascular problems
Poor blood flow can cause erectile dysfunction. If you visit your doctor, he or she will ask if you have difficulty obtaining an erection, if it is suitable for penetration, if the it can be maintained until the partner has achieved orgasm.
   If hardening of the arteries has made your coronary arteries narrow and stiff, that means arteries elsewhere in your body are probably also affected. Atherosclerosis can prevent enough blood flow from reaching your heart, legs, brain and penis. When atherosclerosis affects blood flow to your penis, the blood can't sufficiently fill the penis to allow a suitable erection.
   Endothelial function plays a very important role in the process of male erection. Erection problems and coronary artery disease overlap in risk factors and clinical outcomes. Endothelial dysfunction is considered to be their shared causal factor. Patients presenting with difficulties with erection should be investigated for coronary artery disease, even if with no heart disease symptoms. Earlier diagnosis of erection problems can facilitate prompt intervention, reduce long-term complications, especially the risk of coronary artery disease, and provide effective treatment for erection problems.

Benefit of Viagra and other ED drugs
There is no doubt that Viagra, Cialis, and Levitra improve an erection problem. However, there are risks to these prescription erection pills including optic nerve damage and blindness. We prefer natural erection enhancers such as aphrodisiac herbs. Natural male erection enhancers work slower that prescription erection pills, but after a few days their overall sexual enhancement is comparable or even better than the drugs.

Erection pill
Quite a number of erection pills are available, from the pharmaceutical ones to single herb products to combination erection herbal products. Even though the drugs work quicker, many of the herbal erection pills, over several days, provide a more natural approach. After several days, a spontaneous erection may occur with erection herbs, including a nocturnal erection and morning erection.

Vitamin
There are some vitamin and supplement products that offer natural erection help. Most of the regular vitamins, such as vitamins A, B, C, D, and E do not have much of an immediate influence on penile erection and do lead to a harder erection. However, certain vitamin like nutrients, for instance choline, can be considered an erection vitamin.

Is there a natural vitamin or herb that can reduce erection and sex drive. I am too horny all the time and it distracts me from my work performance.
   5-HTP is a natural supplement that can reduce sex drive and erection strength. 5HTP converts into serotonin which can inhibit an erection. Serotonin (5HT) has two distinct, opposite and positive effects on sexual function, with 5HT-(1A) agonists decreasing ejaculatory latency and erection, and 5HT-(2C) agonists increasing both erection and ejaculatory latency. Kava herb and 5htp interfere with optimal erection and sensation.

Erection herbs
Which herb is best for a harder erection in a man?
   There are quite a number of herbs that help maintain a hard erection. Some of the strengthening herbs include yohimbe, tongkat ali, muira puama, catuaba, tribulus terrestris, horny goat weed, and maca. Many men report a harder morning erection after taking these herbs for a few days.

Alcohol has a negative effect
Chronic alcohol intake leads to a weak erection, which may be due to the decline of testosterone level and decline of penile smooth muscle strength. Alcohol also acts as an anesthetic, reducing sensation of the penis.

Smoking harm
Cigarette smoking is a risk factor for erection problems. Nitric oxide has been demonstrated to be the principal agent of cavernous smooth muscle relaxation and penile erection. Cigarette smoke interferes with optimal nitric oxide production and can lead to a weak erection in a man.

Priapism persistent penis erection
Priapism is a medical condition of persistent penile erection in the absence of sexual excitation. Although priapism affects only a small population of men, it carries major significance. Possible complications of this persistent erection includes penile fibrosis and permanent erectile dysfunction. Priapism can sometimes be caused by taking Viagra, Cialis, or Levitra erection pills, particularly in high dosages.

REM sleep
Penile erection and micturition events triggered by electrical stimulation of the mesopontine tegmental area.

Erection oil products
We don't have extensive information on erection oil products, however it seems unlikely one would get a strong erection by applying an oil to the penis.

questions
Q. I can get an erection but have trouble to maintain erection. Could the beta blockers that I take for blood pressure cause me the problems with erection maintenance?
   A. Yes, in order to maintain erection strength, your doctor may need to switch you to another type of blood pressure medication that does not cause erection problems.

Q. I have a 3 inch erection of my penis but I am looking for a huge erection that is rock hard and stronger.
   A. We am not aware of an erection pill that increases penis size. But, it is possible to keep a bigger erection with natural herbs.

Q. Will erection herbs cure my problem over time if it is due to psychological stress?
   A. Yes, many herbs used as erection enhancers can overcome erection problems due to psychological or emotional stress.

Q. According to your personal experience what herb (other then Yohimbe) works best for increasing the erection duration? I don't use Yohimbe bark extract anymore since I don't like the feeling.
   A. We am not aware of any herbs that work as quickly as yohimbe for erection enhancement, but you can see try some of the herbs mentioned on this page that could help you.

Q. I am looking for an erection enhancer. Have been experiencing erection problem and climaxing difficulties. Recently my doctor prescribed Atenolol 25 mg and I think that is when my erection problems started. Would it be okay to take Prostate Power Rx with Atenolol?
   A. Atenolol is a blood pressure drug that can cause erection problems. If you doctor approves, you can try Prostate Power Rx since it has some erection enhancing benefits.

Q. 1. After prostate removal, the nerve bundles that provide the chemical needed for an erection were not cut, but damaged. Result - no erection without Viagra, and then not very satisfying. Do you have any herbal help? How to get that chemical into the penis? How to stimulate the nerve bundles?
   A. In some people Passion Rx has helped but this is a a difficult condition to treat effectively.

Q. I have had prostate cancer and the prostate removed by radical surgical procedure. I am 59 years old and in good health, want to have sex but cannot get an erection hard enough for intercourse.
   A. There are a number of herbs and combinations used as erection enhancers. It is impossible to predict in any person which one or which combination will work.

Q. I am very much worried about my sexual life with my wife because I have destroyed my massive erection power by using Viagra too much now I am getting married soon and I am very much worried about that. I can't use Viagra for my whole life for erection dysfunction.
   A. Natural herbs for erection enhancement are good options to try. Erection dysfunction can be treated effectively in many cases using natural aphrodisiac herbs.

Q. I'm 63 almost 64 years old. I'm being treated for low testosterone and still am lacking in the desire and erection quality department. Will Passion Rx work for me and help me to feel like a man again with a stronger erection? Even with the testosterone gel that I apply daily there is no fire and very little help with the erection firmness and size. In order to have sex I take various natural erection supplements, some work others don't do anything at all. I am looking for help.
   A. Passion Rx with yohimbe is quite popular and has a high reorder rate, but it is not possible to predict in any one individual what the response would be. Most people take this product two days on, or or more days off. It seems to work for most people within a week.

Q. What herbal products might you suggest that might bring a 64 yr. old man back to normal erection function - who has a rock hard erection just before waking up in the morning and just before sexual encounter and goes soft just before insertion? Also he can't even get an erection if he tries to masturbate !I'm thinking (and l have been told) it could be psychological as well ! (and do you have anything available for that as well), This started happening on and off over a yr. ago (off and on) I do understand that happens in much younger men and now has a (seemingly) permanent loss of erection thing ! Do Progesterone and testosterone creams help that much? Would pregnenelone and/or DHEA aid an erection?
   A. Firstly, it is important to read the cautions regarding impotence in a male, particularly someone who is older since there can be vascular problems causing the erection problem. Secondly, it is not possible to predict in any one individual which single herb or combination formula will be an effective erection enhancer. DHEA and pregenolone may help some users, but these hormones carry side effects. There are a number of herbs that can be tried, including tribulus terrestris extract, tongkat ali, catuaba, etc.

Q. Though I test in the normal range of testosterone and other hormones, I have trouble with erections when I need them and am wondering if there is a blood test to determine the level of nitric oxide in a person's system and whether I am in the normal range? Perhaps I need to take a supplement as an erection enhancer to increase nitric oxide in my system. What do you think of arginine or citrulline as erection enhancing pills?
   A. Citrulline or arginine may raise nitric oxide levels, but their effect is transient and we do not consider these supplements effective erection enhancers. Rather than focusing on nitric oxide levels, consider trying any of a number of erection enhancing herbs or supplements that work in multiple ways to improve erections.

Q. I had a Radical Robotic Prostatectomy September 2008 and neither nerve could be spared, re non-nerve sparing. PSA is non detectible, so that was good, but too bad to lose the nerves. I have had some success using a vacuum pump, but the penis erection deflates easily even with using a ring. I was wondering if any of the herbs, Muira, Mucuna, Tribulus, Catuaba, would help especially to maintain blood in the penis better, and more firmness and if any of the herbs would improve nitric oxide, etc. I could have sex 3 or more times daily before, in some cases 5 times daily - something my Dr. kind of scoffed at. I was not bragging, but stating I had been healthy and functioning well except for the prostate cancer, so thought I would have a good recovery and function even without the nerves if I used the best methods and nutritional support. My Dr. prescribed MUSE, and the Injection as well and said that works real well (don't know exactly what he means by real well)
and to continue using the pump. I don't know if there is any slight chance, rare if at all, that the nerves could regenerate over time (2 - 3 years perhaps). and if some
of the nutrients in an herbal formula would be helpful in maintaining a better erection. I have plenty of desire, libido and interest still, just not as good function. I don't have other health issues other than the one I described.
   A. It is difficult to predict the response to herbal supplements for improving erections in those with radical prostatectomy and potential nerve damage. Much could depend on the extent of the nerve damage. If you doctor approves, you could try low dosages of an herbal formula or individual herbs, and over time perhaps there could be some improvement.

Q. I'm looking for an erection enhancer supplement. I'm 41 220 lbs i know I'm over weight but have working it down and changing my eating habits to a more healthier style. I don't like to take Viagra because the erections feels artificial.
   A. It may take trial and error to find a good and natural erection enhancer that works for you.

Q. I'm a 25 year old male of average weight and height who has had erection problems for almost two years. During intercourse, oral sex, and masturbation, I have an inability to produce a full erection and maintain a moderate erection. My primary care physician had me undergo expensive blood tests to check for hormonal imbalances and other problems. Everything came out normal. I was examined by a urologist about a year ago and he determined that it was physical impotence caused by diminished blood flow to the penis hence the erection problem. During the two-night Sleep Test, I was able to produce but not maintain a moderate erection. My urologist prescribed 20mg of Cialis, which was able to produce a moderate erection during masturbation but with the side effects of eye pain and headaches. I then tried 10mg, which produced the side effects WITHOUT maintenance of a moderate erection during intercourse and oral sex. I shouldn't even be on erection drugs at my age-and it's even worse that they don't work properly on me, not to mention how embarrassing it is going to the pharmacy and urology office. I'm now desperate for answers and avoiding sex, which is all quickly deteriorating my mental health and self esteem. I have spent hours online looking for supplements and reading articles, which has now led me to believe that excessive masturbation is the culprit. Since the age of 12, I've masturbated about 2x/day. I asked my urologist if frequent masturbation in adolescence can eventually cause erection problems and he said "No because then every guy would have the problem." Is it harmful to still be doing it 2x/day at the age of 25? It is possible that I may be addicted to porn, especially now that the erection problem would even prevent me from making a move on a gorgeous girl who's throwing herself at me. However, I recently spent two weeks abroad and during that time I had no desire to look at porn or even masturbate. It only happens when I'm bored at home.
   A. It may take trial and error to find out which herbal formula or single herb can be most effective for an erection problem. Don't expect an effect within a few hours. The benefits of natural herbal erection pills often take a few days to work. Good options for erection problems include Passion Rx, with or without yohimbe, tongkat ali or LJ100, mucuna pruriens, tribulus terrestris, and catuaba. It is a good idea to take a day off after every 2 days. Use the products by themselves rather than combining them. Reducing masturbation and reducing watching porn could help when being with a woman since masturbating too much or seeing too much porn may reduce sensation and interest from being with a woman.

Q. I was wondering which product do u suggest I try that will assist me in enhancing erections. I'm 41 years old. I can get and maintain a erection but I need a little supplement assistance normally.
   A. There are a number of natural herbs that are effective as erection enhancing purposes, including mucuna pruriens, tongkat ali, tribulus terrestris, and others. It is difficult to predict the response in any one person. It takes a few days for these herbs to be effective.

I still have sex though I feel like my erection isn’t the way it was. I can wake up in the morning without an erection which doesn’t start my day well. Sometimes its slightly there. But I believe it was because the 1st time I had sex I was older (21 years) and scared of what to do and my 1st galfriend was cheating on me so all that stress must be the reason as to why I lost my erections. So do u advice Passion Rx to help me eradicate this? Went for checkups and am so healthy. At 24 years, surely I think I can overcome this. If its passion Rx, shd I take the one with Yohimbe or the One without.
