An erection problem, or dysfunction, is one of the commonest disorders of male sexuality. Penile erection depends on a complex interaction of psychological, neural, vascular and endocrine factors. Testosterone hormone has an important role in this process. Neurotransmitters are also involved in starting and maintaining a better penis erection including dopamine and nitric oxide. Men who have difficulty with erection or a weak erection seek an erection ring, erection pump, erection vacuum device, erection cream, or search for an erection pill such as Viagra or herbal erection pills. To maintain a strong penis erection, it is best to have a good 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. Before you take any prescription medications or natural supplements and aphrodisiacs for erection problems, please make sure you read the cautions listed on this impotence page.

Subscribe to a FREE Supplement Research Update newsletter. Once or twice a month you will get research information on several studies on various supplements and natural medicine topics -- including ways for a better erection -- and their practical interpretation by Ray Sahelian, M.D.

A Unique Blend
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 research, a unique proprietary blend with more than a dozen herbal extracts from the best raw material suppliers has been created. The exact dosages and potencies of this effective erection pill blend is a close kept secret only known to the doctor and his research staff. You will only find this exact combination in Passion Rx.

How an erection Happens - erection control
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) to maintain and keep the erection. 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 erectile response: latent, tumescent, full erection, rigid erection, and detumescent. The key biochemical event in erectile 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.

Erection problems due to poor blood flow
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.

Penis erection and Viagra
There is no doubt that Viagra, Cialis, and Levitra improve an erection problem. However, there are risks to these erection pills including optic nerve damage and blindness. I prefer natural erection enhancers such as aphrodisiac herbs.

High Quality products formulated by a medical doctor
Consider highly popular all natural products. These top quality products include Mind Power Rx for better mental focus, concentration, and mood; Diet Rx which helps you eat less.

Erection ring
Erection rings are popular sex toys for boys and men, and can be used for foreplay, intercourse or masturbation. By preventing blood flow to return, they enhance erection.

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

Erection vitamin
There are some vitamin or 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.

NO erection - NO meaning nitric oxide
Nitric oxide is a chemical in the bloodstream that helps dilate blood vessels, including those in the penis, thus maintaining and improving an erection.

Average erection
Average erection length is about 5 to 6 inches, a large erection size would be over 7 inches. A small erection would be less than 4 inches.

Erection Research
Recent insights into androgen action on the anatomical and physiological substrate of penile erection.
Asian J Androl. 2006 Jan;8(1):3-9.
Erectile response is centrally and peripherally regulated by androgens. The original insights into the mechanisms of action of androgens were that androgens particularly exert effects on libido and that erections in response to erotic stimuli were relatively androgen-independent. It was shown that sexual functions in men required androgen levels at the low end of reference values of testosterone. So it seemed that testosterone was not useful treatment for men with erectile difficulties, particularly following the advent of the phosphodiesterase type 5 (PDE5) inhibitors. However, approximately 50 percent of those treated with PDE5 inhibitors discontinue their treatment. A number of recent developments shed new light on testosterone treatment of erectile dysfunction in aging men. In contrast to younger men, elderly men might require higher levels of testosterone for normal sexual functioning. Several studies have indicated that PDE5 inhibitors are not always sufficient to restore erectile potency in men, and that testosterone improves the therapeutic response to PDE5 inhibitors considerably. There is growing insight that testosterone has profound effects on tissues of the penis involved in the mechanism of erection and that testosterone deficiency impairs the anatomical and physiological substrate of erectile capacity, reversible upon androgen replacement. The synthesis of PDE5 is upregulated by androgens, and the arterial inflow into the penis is improved by giving androgen.

Melanotan-II: investigation of the inducer and facilitator effects on penile erection in anaesthetized rat.
Neuroscience. 2005 Dec 14;
The effects of melanotan-II, a non-specific agonist of melanocortin receptors, on erection and its possible sites of action were investigated in anesthetized rats. These results lead to the conclusion that central and peripheral melanocortin pathways are recruited by melanotan-II, depending on its route of delivery, to exert both inducer and facilitator activities on erection. Improve erection.

Characteristics of sildenafil erections in healthy young men.
Asian J Androl. 2005 Dec;7(4):395-8.
To determine the effect of sildenafil citrate on the nocturnal penile erection (i.e. time to onset, the duration of erection, and the interval between first and second erections) of healthy young men. Twenty-two potent men, 23-29 years old, were recruited for the study. All subjects completed three sessions over consecutive nights using the RigiScan monitoring device (Dacomed, Minneapolis, USA). After a first night of adaptation, night 2 records were their baseline values, and on night 3 they received 100 mg of sildenafil citrate. The mean time to onset of the first erection with sildenafil citrate was 34 minutes, whereas it was 74 min without sildenafil citrate. The interval between first and second erections was shorter with sildenafil citrat. The duration of the last erection was statistically significantly longer with the sildenafil citrate. Healthy young men achieved erection within 34 min after sildenafil citrate administration, which is shorter than the 1 h interval proposed by the manufacturer. The interval between the first and second erection was shorter and the duration of the last nocturnal erection was longer.

Pro- erection effects of an alkaloidal rich fraction from Aspidosperma ulei root bark in mice.
J Ethnopharmacol. 2005 Oct 13;
In recent years, there has been a renewed interest in the search for novel natural substances active against erection dysfunction. Plants that belong to the genus Aspidosperma (Apocyanaceae) are known to be very rich in indole alkaloids and have an ethnomedical history of use as traditional remedies for erectile dysfunction. This study examined whether the indole alkaloidal rich fraction from Aspidosperma ulei Markgr. root bark could manifest penile erection -related behavioral responses (penile erection, erection -like and genital grooming) in mice. These results point out that F(3-5) facilitates penile erection in mice possibly through the activation of central dopamine and blockade of presynaptic alpha-2 adrenoceptors with a subsequent enhancement in nitric oxide release from the penile nerves and arteries. This study further supports the traditional use of extracts from Aspidosperma species in erection dysfunction.

Erection enhancement
It is quite possible to get an erection enhancement with impotence drugs and natural supplements.

The 10 year Erection
Charles "Chick" Lennon, 68, received a steel and plastic implant in 1996, about two years before Viagra went on the market. The Dura-II is designed to allow impotent men to position the penis upward for sex, then lower it. But Lennon could not position his penis erection downward. He said he could no longer hug people, swim or wear bathing trunks because of the erection pain and embarrassment. In 2004, a jury awarded him $750,000. A judge called that excessive and reduced it to $400,000. A lawyer representing both Dura-II manufacturer Dacomed Corp. and the company's insurer have declined to comment. Dacomed has maintained that nothing was wrong with the implant. The implant consists of a series of plastic plates strung together with steel surgical wire, almost like a roll of wrapped coins. Springs press against the plates, creating enough surface tension to simulate an erection.

Erection emails

   A. It's difficult to say what your exact medical problem is since we don't have a doctor's diagnosis. We are not familiar with semen thickness having anything to do with erections.

Q. According to your personal experience what herb (other then Yohimbe) works best for increasing the erection duration? I don't use yohimbe anymore and I don't like the feeling.
   A. I am not aware of any herbs that work as quickly as yohimbe for erection enhancement, but you can see some of the herbs mentioned on this erection pill site (see link top of page) that could work after a few days.

Q. I am looking for an erection enhancer. Have been experiencing erection problem and climaxing difficulties. Recently taken off Atenolol 25 mg. On Tildiem Retard 90 mg twice daily. Atorvastatin 80 mg. Ezetimibe 10 mg. Clopidogrel 75 mg. Been on Prozac 20 mg for 17 years and recently been put on Modafinil 400 mg (last 5 months). Can I take 5 mg DHEA and Passion-Rx without Yohimbe.

Tildiem is a calcium channel blocker, atorvastatin is a statin drug, clopidrogel is a platelet inhibitor, ezetimibe is used for high cholesterol. Some of these drugs could influece erection, particularly Atenolol and Prozac and to a lesser extent Tildiem.

Q. I am 24 yrs old. And lately i have been this problem that whenever i am having sex then after losing my sperm I lose my erection. I never used to face this kind of erection problem.

Will cordyceps work maybe for erection enhancer.
   A. There are dozens of herbs for sexual health and to improve erection, it is difficult to predict which will work in any particular person. Cordyceps is not a potent erection enhancer like some other sexual herbs.

Q. 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?
