MEDLINE is the U.S. National Library of Medicine's (NLM) premier bibliographic database that contains over 18 million references to journal articles in life sciences with a concentration on biomedicine. A distinctive feature of MEDLINE is that the records are indexed with NLM Medical Subject Headings (MeSH).The great majority of journals are selected for MEDLINE based on the recommendation of the Literature Selection Technical Review Committee (LSTRC), a National Institute of Health (NIH)-chartered advisory committee of external experts analogous to the committees that review NIH grant applications. MEDLINE is the primary component of PubMed, part of the entry series of databases provided by the NLM National Center for Biotechnology Information (NCBI). MEDLINE may also be searched via the NLM Gateway (23).

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!


Vitamin C has been associated with higher sperm counts. You can get it naturally from strawberries, raspberries and blueberries, which are anthocyanins, colorful plant chemicals which help keep your arteries unclogged, boosting circulation and erection quality. In supplement stores, you’ll find all manner of megadoses — steer clear of those; they might do more harm than good.
A conflicting study of 22 subjects found that a 100mg daily dose of yohimbine for 30 days did not significantly improve penile rigidity. Three subjects experienced a notable increase in penile rigidity and twelve subject experience a partial increase in rigidity. [13] These findings do not completely discount the use of yohimbine to treat erectile dysfunction, but do suggest the compound's effects, even at very high dosages, will cause varying responses across a similar population.
In a study with human subjects, Kruger et al. have reported that acute changes in the normal physiological levels of PRL led to a significantly prolonged ejaculatory latency, but minor reductions of sexual drive and function.[19] Although zinc induced elevation of PRL was not an acute effect, findings similar to the human study (prolongation of ejaculation and mild reduction of libido index with medium dose of zinc) were observed in this study. However, the prolongation of ejaculatory latency may not be merely due to effects of elevated PRL because elevated PRL levels are known to be associated with the negative aspects of sexual activities (decreased sexual desire and frequency of sexual intercourse).[20]
However, the case is entirely different for Niacin, as it is not only relatively more convenient, but also it allows men to enjoy sex any time when they want even when they take Niacin for only one time in a day for erectile dysfunction. Niacin formulates in the form of various slow-release pills designed primarily to seep in a slow way within the human bloodstream during the course of one day.

Long prescribed for women who want to restore muscle tone after childbirth, pelvic floor exercises, also known as Kegel exercises, can benefit men significantly too. A study by researchers at the University of West of England in Bristol showed that pelvic floor exercises can help men with erectile dysfunction and premature ejaculation. Furthermore, experts think these exercises can make orgasms stronger. Once learned, pelvic floor exercises can be done any time, even while doing other things.
Penile erection is a hemodynamic process involving increased arterial inflow and restricted venous outflow, coordinated with corpus cavernosum and penile arterial smooth muscle relaxation. Any problem in this mechanism results in Erectile Dysfunction and its etiology is generally multifactorial. This study is aimed at determining the objective outcome of aerobic training in the management of Erectile Dysfunction of arterogenic origin using Meta analysis.
However, you might actually be better off going one step back in the chain reaction and taking an L-citrulline supplement. While your body converts L-arginine to nitric oxide, it also metabolizes it too fast when the amino acid is taken in an oral supplement, according to a 2011 study from the University of Foggia in Italy. L-citrulline, which the body converts to L-arginine, is actually a better option to follow the same metabolic pathway and serve as a treatment for ED, the same study found.
Does diabetes cause erectile dysfunction? Diabetes can lead to lower levels of testosterone, and this can result in erectile dysfunction. Controlling blood sugar levels, maintaining a healthy weight, getting exercise, and reducing stress are all ways of reducing this problem. Hormone therapy, Viagra, and counseling are some ways that medicine can help. Read now
Yohimbine. This chemical is found in the bark of an African tree called yohimbe. It has been used as a male aphrodisiac in Africa, and under medical supervision it has been used as a prescription drug to treat ED. Supplements made from yohimbe bark are also available without a prescription, but they can be life-threatening if used at high doses, according to the Natural Medicines Comprehensive Database. The supplement can interact in a harmful way with certain drugs, such as blood pressure medications, and should be avoided by anyone with liver, kidney, heart, or diabetes problems or problems with anxiety or depression. Like DHEA, yohimbine should not be taken without a doctor's supervision.
Using the protocol of a clinical randomized placebo-controlled parallel-group trial, the study also took place at the University of Hong Kong. One hundred sixty male patients with ED and dyslipidemia were randomized into two groups receiving either up to 1,500 mg of oral niacin daily or placebo for 12 weeks. Using questions from the International Index of Erectile Function (IIEF, particularly questions Q3 and Q4), the primary outcome was improvement in erectile function. Q3 ranked “frequency of penetration,” while Q4 ranked “frequency of maintained erections after penetration.” Other outcome measurements included the total IIEF score, IIEF-erectile function domain, and Sexual Health Inventory for Men (SHIM) score.

The Florida Sexual History Questionnaire, a 20-item questionnaire that assesses interest and desire for sexual activity, sexual development, current sexual behaviors, and satisfaction with current sexual activity, was used to assess male sexual dysfunction. Individuals responded to each question by choosing one of six ordinally scaled response categories, with higher scores representing better functioning. Scores on the Florida Sexual History Questionnaire have been shown to significantly discriminate between men with and without impotence25 and between men with primary organic and primary psychogenic erectile dysfunction.26 According to Geisser et al,25 the Florida Sexual History Questionnaire has high internal consistency as well as split-half reliability. Chronbach's alpha has been reported to be as high as 0.90, and Spearman Brown's coefficient is reported to be 0.86.
In fact, one common reason many younger men visit their doctor is to get erectile dysfunction medication. Often, men with erectile dysfunction suffer with diabetes or heart disease, or may be sedentary or obese, but they don’t realize the impact of these health conditions on sexual function. Along with erectile dysfunction treatment, the doctor may recommend managing the illness, being more physically active, or losing weight.
Where it comes from: Yohimbe is derived from the bark of a west African evergreen tree. Yohimbine is an active chemical (an alkaloid) found in said bark and is cultivated into supplement form. Yohimbine hydrochloride is a standardized form of yohimbine that is available as a prescription drug in the United States. These terms are all related but are interchangeable.

In the 18th century, Spain embraced the Age of Enlightenment, directing the beacons of thought to all endeavors. But while Spain was not as advanced as France, Britain, Germany, or America, its new political thinking led to the revocation of most of the historical rights and privileges of the sub-kingdoms that comprised the Spanish Crown. Those changes, in turn, allowed for the freedom of inquiry that was so needed for medical discovery, among others.
Medicines like I-Arginine and viagra, can fix your problems for hours but vitamins and amino acids will cure erection problems for long term. Remember, not to take vitamins and medications (I-Arginine) at the same time as it can react in your body. Discuss your doctor before adding any vitamin to your routine. Apart for I-Arginine and other pills, here we have given some vitamins to quick fix your problem and have a better sex life.

ICI Alprostadil may be used as a mixture with two other drugs to treat ED. This combination therapy called "bimix or trimix" is stronger than alprostadil alone and has become standard treatment for ED. Only the Alprostadil ingredient is FDA approved for ED. The amount of each drug used can be changed based on the severity of your ED, by an experienced health professional. You will be trained by your health professional on how to inject, how much to inject and how to safely raise the drug's dosage if necessary.
Over 18 million American men over 20 years old suffer from erectile dysfunction, a condition characterized by the inability to keep an erection. It’s a complex disorder brought on by a number of factors, but it’s almost always devastating for the man it affects — causing him to lose confidence in himself and different aspects of his life. The stress it causes can deteriorate relationships and lead to lost productivity at work. Health problems aren’t uncommon either. But there’s good news in all the bad; a new study finds exercise may be a simple way to get things going under the sheets again.
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.
Men typically have higher zinc needs than women, which can make them more vulnerable to zinc deficiencies. In men, zinc is also needed to support healthy prostate and penile function. Keep in mind that excessive amounts of zinc can be harmful so it is best to follow package directions on the supplement you choose, should you decide to supplement with the mineral.
Taking high doses can also cause other severe problems, including difficulty breathing, paralysis, very low blood pressure, heart problems, and death. After taking a one-day dose of yohimbine, one person reported an allergic reaction involving fever; chills; listlessness; itchy, scaly skin; progressive kidney failure; and symptoms that looked like the auto-immune disease called lupus.
In the present study zinc caused an elevation of T. This showed an increase from 2.39 to 8.21 ng/dl after two weeks of zinc treatment. This elevated T level may have contributed to the increase in number of penile thrusting (from 26.5 to 52.8) observed. Supplementation with 459 μmol/day of zinc for three months, in marginally zinc deficient healthy elderly men, has been shown to increase the levels of serum T from 8.3 to 16 ng/dl.[25] Laboratory experiments indicate that the nitric oxide erectile pathway is T dependent.[26] Many studies using animal models have confirmed that T is important in modulating the central and peripheral regulation of erectile dysfunction. T deprivation has a negative impact on the structure of penile tissues and erectile nerves.[27] Thus, elevated T levels subsequent to zinc supplementation may increase the sexual competence via rigid and sustained erection. This may promote greater tactile stimulation of the penis due to increased contact with vagina.[25]
Oysters are also a great source of zinc, with just 3 ounces providing 493% of your recommended daily intake. In fact, oysters are so rich in zinc that eating too much can cause an accidental zinc overdose, so just be wary of this. Bear in mind as well that oysters are a common source of food poisoning, and they are also very high in cholesterol – might be best to stick to your nuts and seeds!

However, Viagra can have unpleasant side effects, and an overdose can be serious. We cover everything you need to know about Viagra in this article. Read now
Motivated by philosophers that included John Locke (the most influential of Enlightenment thinkers), Voltaire, Newton, and Leibniz, ruling princes throughout Europe endorsed and fostered the intelligentsia of the Enlightenment. Some of these rulers even attempted to apply the ideas of the enlightenment to government. When grasped by “natural aristocrats,” the Enlightenment was particularly successful in America where it influenced Benjamin Franklin and Thomas Jefferson, among many others, and fueled the fires that led to the American Revolution, the Declaration of Independence, and the creation of the United States.
These are not currently approved by the FDA for ED management, but they may be offered through research studies (clinical trials). Patients who are interested should discuss the risks and benefits (informed consent) of each, as well as costs before starting any clinical trials. Most therapies not approved by the FDA are not covered by government or private insurance benefits.
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.
Evidence from 5 randomized studies published in the years between 2004 and 2010, has demonstrated strong evidence that aerobic exercise can benefit people with arterogenic ED. These review results of this study build on and update the evidence from studies that concluded that concluded that exercise was beneficial for people with ED and cardiovascular disorders (25–27); on ED and obesity (18) and on normal subjects with ED (24). However, studies have shown common pathway for ED, cardiovascular (28 –30) and metabolic disorders (19, 31).

Can one of the B vitamins actually improve erectile dysfunction?  The research makes a strong case that Niacin, a.k.a. Vitamin B3, does indeed do just that for a big percentage of men. Of course, this is a inexpensive help to erectile issues, as high niacin foods and supplements are cheap and readily available.  Below I summarize the most prominent human evidence to date that shows which men will likely benefit and why:
In addition to lowering low-density and total cholesterol along with triglycerides, increasing high-density lipoprotein cholesterol (HDL-C) has become one of the principal objectives for treating hyperlipidemia. Considerable evidence has shown that even a minor improvement in HDL-C levels may significantly reduce cardiovascular risk. For example, it has been found that an increase of 1 mg/dl in HDL-C levels results in a parallel reduction in coronary artery disease risk by 2% in men and 3% in women. Moreover, HDL-C helps to transport oxidized cholesterol from peripheral tissues where it instigates atherosclerosis to the liver for excretion. Furthermore, HDL-C has potential anti-inflammatory, anti-thrombotic and anti-oxidant effects.

Any problem in this mechanism results in Erectile Dysfunction and its etiology is generally multifactorial. This study is aimed at determining the objective outcome of aerobic training in the management of Erectile Dysfunction of arterogenic origin using Meta analysis.
Much higher doses have been used in certain studies, sometimes up to 100 milligrams daily. However, this is considered a very high dose that is potentially dangerous and likely to cause some side effects. Overall, it’s best to start with small doses while monitoring your reaction. Speak to a doctor or herbal practitioner before increasing your dosage to high levels.

However, for most men who experience erectile dysfunction, their overall experience can be improved even further through regular exercise. There are many reasons why exercise improves sexual satisfaction. For one thing, regular, sustained exercise can lead to the release of chemicals called endorphins that are responsible for the so-called runner’s high, and which stimulate the release of sex hormones. Exercise also generally improves mood and imparts a sense of calm afterward, with lower heart rate, lower blood pressure, better digestion, and lower levels of stress hormones.
