When a man becomes sexually excited, muscles in their penis relax. This relaxation allows for increased blood flow through the penile arteries. This blood fills two chambers inside the penis called the corpora cavernosa. As the chambers fill with blood, the penis grows rigid. Erection ends when the muscles contract and the accumulated blood can flow out through the penile veins.
I recently treated a young twenty-something man with a primary complaint of erectile dysfunction. When he started to notice this issue, he attempted to treat it by performing lots of kegels. (If you haven’t heard of kegel exercises, they’re done by repeatedly contracting and relaxing the muscles that form part of the pelvic floor, as if you were trying to stop peeing mid-stream.) I found this man’s story interesting because, as we discovered, in his case the kegels actually did more harm than good. We found that once he stopped kegeling and allowed his pelvic muscles to relax, his erections became stronger and he was able to ejaculate without any issues.
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:

Wistar rats (From Medical Research Institute, Colombo) were obtained and kept in a well ventilated animal house under natural dark light cycle (temperature 28-30°C, humidity; 50-55%). Animals were housed in groups (four per group) until they reached sexual maturity (150-200 g). They were provided with pelleted food and water. Male rats were permitted access to receptive females on three separate occasions and then screened for sexual proficiency. Male rats who displayed consistently vigorous sexual activity were selected for the study.


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.

Eggs a supplement? Yup. Testosterone is derived from cholesterol, and eggs are the healthiest way to ensure you’re getting enough of the good kind (LDL cholesterol). Plus, eggs are rich in choline, a powerful natural chemical that not only burns fat but can help set your pants afire. Choline triggers the production of nitric oxide (NO), which relaxes arteries in the penis and enables blood flow to do its thing. Choline is a precursor to acetylcholine, a neurotransmitter which controls sexual behavior through its activity in the brain; having a higher level of AcH has been associated with more frequent sex and more intense, longer orgasms. And that’s not all: Check out these things that happen to your body when you eat eggs!

If ED continues to be a problem even after making certain lifestyle changes, talk with your doctor. ED is an uncomfortable subject for many men to discuss, but it’s treatable in most cases, so there’s no reason to avoid getting help. Doctors see patients every day about ED, so you’re simply one of millions of men dealing with this common condition.
In a recent study, moderate-intensity exercise such as walking briskly and light cycling was shown to boost mood for up to 12 hours. Exercising every day might be best to lift your mood, but strive for at least 5 days a week. Another study showed exercise can improve your body image, regardless of body weight or shape. And feeling good about your body is a great start toward making the bedroom a happier place.

A yohimbine HCL dosage of 0.2 milligrams per kilogram of bodyweight taken on an empty stomach immediately upon waking or in-between meals ramps up fat oxidation without causing undesirable side effects like high blood pressure or racing heart. [3] The table below provides a guideline on how many 2.5mg capsules of yohimbine HCL you should take based on your weight and the recommended dosage:
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.

One study found that sticking to a Mediterranean diet rich in virgin olive oil, vegetables, fruits, whole grains, nuts, and fish was associated with a lower risk of ED development and improvement in people who already suffered from ED. There is also some evidence that vegetarian and vegan diets may lower the risk of some types of heart disease, which in turn decreases the likelihood of developing 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.
Erectile dysfunction is obviously a frustrating health condition caused from different types of physical body problems. This may cause struggle with the self-esteem for both the man as a patient and his life partner. Luckily, individuals may take various supplements in the form of vitamins to deal with the root cause leading to the problem of erectile dysfunction. In this article, we will discuss about the role of Vitamin B3, known scientifically as Niacin to overcome the condition of erectile dysfunction among men.
Stimulant drugs speed up the nervous system. By speeding up the nervous system, stimulant medications can make you feel jittery and speed up your heartbeat. Yohimbe might also speed up the nervous system. Taking yohimbe along with stimulant drugs might cause serious problems including increased heart rate and high blood pressure. Avoid taking stimulant drugs along with yohimbe.
Whether you’re looking to bulk up, or are just concerned about having enough protein to keep your body strong and healthy, zinc is an absolute must have! When we eat protein, it gets broken down by the body into amino acids, and then resynthesized into the different proteins needed by the body, and zinc is a vital part of this process. So even if you are eating lots of protein, without zinc you won’t be able to use it properly!
Parameters evaluated in this study are determinants of some important aspects of the male sexual competence. Libido index, intromission and mount latencies are indicators of libido, arousability and motivation. Copulatory efficiency and inter-copulatory intervals are indicators of sexual vigor, while penile thrusting is an indicator of penile erection.[8,11,14,15] Our results showed that the libido index was significantly reduced in the 10 mg/day zinc saulphate treated group. In the same group, majority of the animals (62%) failed to complete their sexual behavioral cycle within the observed period. Though these unsuccessful rats showed the initial steps of the cycle such as licking, physical contacts with the females and few mounts and intromissions, they were inactive at later stages. Therefore a significant reduction of the libido index, number of intromissions, mounts, and ejaculations were observed in the high dose of zinc treated group compared to controls.
Controlling stress, having a healthy diet, and getting enough sleep to create a good foundation for sexual satisfaction. But sometimes the basics aren’t quite enough. Millions of men experience erectile dysfunction (ED), but ED can usually be successfully treated with prescription medications like Viagra, Levitra, Staxyn, and Cialis. These drugs have helped men understand that ED isn’t all in their mind, have opened up the topic to a more honest discussion, and have transformed many men’s sex lives.

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.


The researchers noted that "when patients were stratified according to the baseline severity of ED, the patients with moderate and severe ED who received niacin showed a significant improvement in IIEF-Q3 scores (0.56 0.96 [P = 0.037] and 1.03 1.20 [P < 0.001], respectively) and IIEF-Q4 scores (0.56 1.03 [P = 0.048] and 0.84 1.05 [P < 0.001], respectively] compared with baseline values, but not for the placebo group...For patients not receiving statins treatment, there was a significant improvement in IIEF-Q3 scores (0.47 1.16 [P = 0.004]) for the niacin group, but not for the placebo group. Niacin alone can improve the erectile function in patients suffering from moderate to severe ED and dyslipidemia." [3]

Though higher doses of zinc reduce libido, supplementation with a medium dose (5 mg/day) has some beneficial effect on the sexual competence of adult male rats. The major significant effects of this dose of zinc are prolongation of ejaculatory latency without disturbing sexual arousability, motivation, penile erection and sex vigor. Also, the partner preference index of the 5 mg/day group was positive and comparable to the controls. A positive partner preference index is indicative of unchanged sexual interest of males.[16] These results confirmed that libido and sexual interest are not affected by zinc supplementation with a 5 mg/day dose. However, mild reduction in percentage of intromission was observed in this group and it is postulated that this may be situational rather than an effect of supplemented zinc. This is based on our observation where mild rejection by the females at the initial phase of the behavior led some males to refrain from sexual activity.
