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]
Shape up. ED is often linked with restricted blood flow to the penis. Keep your heart and arteries in good condition by maintaining a healthy weight, and following a diet high in fruits, vegetables and whole grains. Avoid saturated fats and trans-fats. Regular aerobic exercise can improve blood flow to the genitals and reduce the stress that can contribute to ED.
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.
Participants in this study gradually increased their daily intake of niacin from 250 mg to 3,000 mg over 36 weeks. Nine of the 23 people who were taking immediate-release niacin withdrew from the study early because of facial flushing, fatigue, or skin discoloration. Eighteen of the 23 who were taking 3,000 mg daily of sustained-release niacin dropped out due to upset stomachs, fatigue, or abnormal liver function tests. All of these side effects disappeared once the participants stopped taking the vitamin. Additional cause for concern comes from other reports suggesting that high doses of sustained-release niacin can cause jaundice and liver failure.
In addition, when research has shown a nutrient such as zinc or niacin to improve sexual function, it's usually in people who are deficient in it. So, before you stock up on over-the-counter nutritional supplements for ED, speak with your doctor. He can test you for deficiencies and steer you toward the most effective and safest way to treat your erectile dysfunction. 
Aids in fat loss: Yohimbe and other alkaloids in the bark extract are said to block specific receptors that actually inhibit fat loss. A three-week study in 1991 observed 20 obese females on 1,000-calorie diets. They were given 20 mg of yohimbe each day and lost three pounds more than the group receiving placebos. Not a drastic weight loss, but enough to give experts hope that yohimbe can help with weight loss. Other studies have found that yohimbe increases the amount of non-esterified fatty acids, a result of fat breaking down. More research is needed. Most other studies in the field are done using the drug yohimbine. Extracted chemicals are not the same as yohimbe bark. Studies with yohimbine are expected to give different results than studies that used the raw plant.
Yes, niacin is good for erectile dysfunction. Vitamin B3 or Niacin acts as a powerful agent to improve the condition of erectile dysfunction and a research study conducted in a medical center of Hong Kong confirmed that Niacin supplementation has resulted in the increase of blood flow across the pelvic region in men. In addition, researchers have further confirmed that the Vitamin comes with the ability to unclog various harmful fats collected in the artery region.
Counselling or sex therapy (58% of people find this works for them) –mind-related causes of erectile dysfunction can affect anyone. They are more likely if you experience erectile dysfunction at a younger age. Talking to a counsellor or therapist can help some people overcome erectile dysfunction related to these problems, possibly for good. They can also help you if your erectile dysfunction is causing you stress, as this can make matters worse.
In the statistical analysis, the difference between the pre-test and post-test values (changed score) for IIEF score was computed. Student t-test was used to compare the mean changed score values of IIEF. All statistical analysis was performed on an IBM compatible micro computer using SPSS for window version 15.0, (Chicago IL, USA). The probability level for all the above tests was set at 0.05 to indicate significance.
You may find that using a vacuum device requires some practice or adjustment. Using the device may make your penis feel cold or numb and have a purple color. You also may have bruising on your penis. However, the bruises are most often painless and disappear in a few days. Vacuum devices may weaken ejaculation but, in most cases, the devices do not affect the pleasure of climax, or orgasm.

Males consuming yohimbine HCL for its pro-erectile benefits should take 5.4mg to 6mg three times per day but don't expect for the results to be noticeable until after about two to weeks of consistent dosing. [4] Not all males will experience this benefit so if you do not notice a change after four weeks of consistent dosing then consider stopping supplementation altogether.
Yohimbe can interact with several drugs and medications, so it’s not safe for everybody to use. Don’t take yohimbe bark if you’re currently taking any ACE inhibitor drug, beta blocker, SSRI drug, MAOI, stimulants or caffeine-containing drugs, or tricyclic antidepressant drugs. Those who have any of the conditions listed below should not take herbal treatments like yohimbe without speaking with a doctor first. This is because it may affect things like blood pressure, heart health, kidney function and neurotransmitter functions:

For Men: Soy is terrible for the male sex drive as the phytoestrogens build up to unnatural levels much too quickly. In fact, an ex boyfriend and I experimented with this when he decided to become vegan. He ate and drank soy products for a month and by the end of that time he had zero libido. Within two weeks of stopping all soy, he was back to normal.
Partner preference index in both 5 mg zinc treated group and controls was positive. In the control group, time spent by males, with estrous and diestrous females, was 21.75 sec. (SEM 2.26) and 13.62 sec. (SEM 1.05) respectively. In the zinc treated group they spent 20.87 sec. (2.09 SEM) with estrous and 14.37 sec. (SEM 0.70) with diestrous females. The PPI of controls and zinc treated group was 8.12 Sec. (SEM 2.32) and 6.50 Sec. (SEM 1.76) respectively. There was no significant difference between the two groups, P > 0.05.

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.
The paired t-test was used to assess differences in responses using various doses of yohimbine in responders and nonresponders. Responder and nonresponder changes in tumescence, rigidity, and other physiologic responses over the entire study period were compared using independent t-tests (assuming equal variances). Independent t-tests were repeated to determine whether significant differences existed in the mean numbers of risk factors, age, or side effects among groups. Matched pairs t-tests were used to compare Florida Sexual History Questionnaire responses at each dose. Finally, χ2 analysis (or Fisher's exact test when appropriate) was used to compare the two groups on dichotomous sexual satisfaction ratings at the end of the trial; 95% confidence intervals were consistently examined to determine the magnitudes of differences detected. Two-tailed P-levels were used in reporting all results. SPSS 9.0 statistical software (SPSS Inc, Chicago, IL, USA) was used for analysis.
There’s a reason why Casanova developed his reputation: He was alleged to scarf two dozen oysters a day, which is the food highest in zinc. In the modern era, people with higher levels of zinc in their system have been shown to have a higher sex drive than those with lower levels. That’s because the mineral is essential for testosterone production. In one Nutrition study, zinc-deficient men who supplemented with zinc for six months doubled their T levels. And another eight-week trial published results in the Journal of the International Society of Sports Nutrition found that college football players who took a nightly zinc supplement showed increased testosterone levels as well.

Male erectile dysfunction (ED) has been defined as the persistent inability to attain and/or maintain an erection sufficient for sexual performance (1). ED is very common, and its prevalence as well as severity increases with age (2). It has been recognized that the major cause of ED is atherosclerosis affecting the pelvic vasculature (3). The presence of ED has been known to predict future cardiovascular disease, and early detection may allow timely modification of remediable risk factors, or lead to the diagnosis of occult cardiovascular disease (4, 5).
But, first for those of you who do not know anything on this topic, let’s define erectile dysfunction. Erectile dysfunction is a condition which characterizes itself with the inability to maintain an erection during sexual intercourse. Luckily, although erectile dysfunction is a common condition, this condition seems to be easily treated. You can choose from the variety of natural remedies, including supplements, which claim to increase your stamina, sexual ability, and muscle mass. This article is dedicated to the importance of exercise as a way to treat erectile dysfunction and highlight the best exercises you could use as a part of the treatment. 
Twenty-one men were screened. Two were rejected because they had normal results on nocturnal penile study, and one man was excluded from the study because of a protocol violation. Eighteen men completed the study. The mean age of the men was 60.2 y (range, 34–69 y). The mean duration of erectile dysfunction was 3.1 y (range, 1–10 y). All men were in stable heterosexual relationships. The listed medical risk factors for erectile dysfunction were hypertension in nine men, atherosclerotic cardiovascular disease in seven, single offending medication in seven (mostly beta-blockers), multiple medications in five, diabetes mellitus in four (one with neuropathy), venous leakage in two, and peripheral vascular insufficiency in one.
A vacuum erection device is a plastic tube that slips over the penis, making a seal with the skin of the body. A pump at the other end of the tube makes a low-pressure vacuum around the erectile tissue, which results in an erection. An elastic ring is then slipped onto the base of the penis. This holds the blood in the penis (and keeps it hard) for up to 30 minutes. With proper training, 75 out of 100 men can get a working erection using a vacuum erection device.
Obesity is a state of chronic oxidative stress and inflammation (38). The increased oxidative stress associated with obesity may increase free radical formation, which could quench and deactivate nitric oxide, reducing its availability for target cells. Weight loss programs with dietary modifications and increased physical activity may lead to reduced oxidative stress associated with improved nitric oxide availability (39). As impaired nitric oxide activity appears to play an important role in the pathogenesis of erectile dysfunction (40), improved nitric oxide availability associated with weight loss may be implicated in the amelioration of erectile function in our series of obese men. A reduced CRP level due to sustained lifestyle changes may have contributed to amelioration of erectile function after treatment. Levels of CRP correlate significantly with reduced nitric oxide availability (41) and increasing severity of penile vascular disease as measured by penile Doppler (42). Moreover, consistent findings support a predictive role of CRP and IL-6 for cardiovascular events in different populations (43), while IL-8 is a potent chemoattractant (44).
A study published in the journal Fertility and Sterility that analyzed the effect of various fruit and vegetables on sperm quality discovered carrots had the best all-around results on sperm count and motility—a term used to describe the ability of sperm to swim towards an egg. Men who ate the most carrots saw improved sperm performance by 6.5 to 8 percent. The Harvard researchers attribute the boost to carotenoids, powerful antioxidative compounds in carrots that help the body make vitamin A.

Three subsets (eight in each subset) of sexually experienced adult male rats were supplemented with three different oral doses of zinc sulphate (a daily dose of 1 mg, 5 mg and 10 mg respectively) for two weeks. A subset of eight animals without zinc supplementation was used as the control group Sexual behavior was observed by placing them individually in cages with receptive females.

The art of acupuncture has become the new treatment for everything from back pain, depression, and even ED. Impotence could be more of a state of mind, and acupuncture may help. Through this alternative therapy, fine needles are placed in various parts of the body to relieve pain or stress. Although there are many mixed studies for acupuncture and ED, many tend to confirm positive results. A 1999 study found acupuncture improved the quality of erection and even restored sexual activity in 39 percent of participants.

In the end, open and honest communication with your therapist will yield the best course of action. If you do decide to try pelvic floor PT, a comprehensive evaluation will determine what exactly is going on with your muscles. They may be tight and weak or they could have poor coordination. So my advice for those suffering from erectile dysfunction is this: before you try kegels, make an appointment with your pelvic floor therapist.

While balancing your sexual focus is singularly the most important aspect of solving a sexual dysfunction challenge, it's important to also address the physical component. This is especially true if you are over 40, or suffer from erectile dysfunction. Exercise increases blood flow and helps your body eliminate toxins. As well as this, exercise also improves your strength, stamina and form.
Taking zinc in supplement form is just one of many treatments for those looking for help with ED. Many men use supplements either to replace prescription medications like Viagra and Cialis, or to enhance the effectiveness of these medications. Some other natural supplements aimed at relieving ED symptoms include Korean red ginseng, L-Arginine, carnitine, and DHEA.
