When men are given supplemental testosterone it can have positive effects on erectile dysfunction as well as the “grumpy old men” syndrome of low energy, loss of drive, low libido, and loss of endurance as well as “man boobs”.  Zinc has a direct effect on the two main enzyme systems that act on testosterone: conversion of testosterone to estrogen via aromatase and the conversion of testosterone to DHT by 5 alpha reductase.   Zinc blocks the testosterone to estrogen pathway leading to more testosterone.  It turns out that only at really high zinc levels does zinc inhibit the 5 alpha reductase enzyme so when we give mild to moderate zinc supplements, DHT actually increases because there is more testosterone to feed into this pathway.   This actually benefits things because DHT has 2-3 times the times the androgen receptor affinity than testosterone.  In any case, we see an increase of testosterone and androgenic activity from DHT with zinc supplements and whether a guy has low or normal T to begin with, there is a positive change in erectile dysfunction and libido in some men due to the increased androgenic activity and less estrogen pulling in the opposite direction.  Conversely we see testosterone levels drop when a diet is low in Zinc as well as a drop in DHT.  It is important to note that this effect of increased testosterone with zinc supplementation, while well established, does not always lead to an improvement of ED and increased Libido.
1. Increased Blood Flow in Men with Lower Niacin Levels.  Of course, there is a lot to an erection, but I think just about everyone would agree that the #1 goal is to increase something called endothelial function.  The endothelium is the delicate lining of the arteries that pumps out nitric oxide and relaxes the arteries.  And, of course, a relaxed, i.e. more open artery is one that allows more blood to flow into your arm, your leg or your brain.  And I'm sure I don't need to explain why increased blood flow into your penile arteries is critical for erectile strength.

Test was terminated after 15 minutes of observation or after ejaculation (whichever occurred first). Ejaculatory latencies were taken as 15 minutes when animals showed intromissions but failed to ejaculate during the test period. After analyzing the results, the following tests were performed with the group that indicated significantly positive effects compared to the controls:
Take note that you may not be able to complete a series of about 10 kegel exercises on your first try. This is just fine. Just do what you can, and gradually work on more kegel exercises until you reach 10 to 20 kegels, up to three times in a day. When performing these exercises, avoid holding your breath, or pushing your stomach, thigh muscles, or buttocks in. It would be helpful if you relax after every count of five. You may also challenge yourself by alternating between long and short squeezes.
Erection is a complex physiological process in which vascular factors play a pre-eminent role. Therapeutic options for men with arteriogenic erectile dysfunction (ED) are mainly administration of phosphodiesterase type 5 inhibitors, intracavernous injections of vasoactive agents (for example, prostaglandin El, papaverine/phentolamine, or triple drug), intraurethral administration of prostaglandin El, and administration of centrally acting drugs (11, 12). However, all of these methods circumvent the patient's problem temporarily, and patients are not cured of impotence, they will remain dependent on these treatments for the remainder of their sexually active lives. An effective treatment that cures the problem permanently is needed where penile revascularization and exercise remain treatment options for such patients. However, due to the complexity of penile revascularization such as cost ineffectiveness, unavailability of experts, side effects of surgery and high failure rates among the elderly (13) have left people with ED at the mercy of exercise.
We studied the involvement of zinc in the sexual behavioral response of male rats. The study design employed a rat model to predict the human sexual response to elemental zinc supplementation. Rats were used because they are very social and copulate under a variety of circumstances, regardless of the presence of a human experimenter. They are practical (small and easy to handle) and certain tissues and neuroendocrine systems are strikingly similar to humans.[13]

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.
Regardless of diet or exercise - to control a sexual act, it's imperative to balance your sexual focus during foreplay, penetration, and intercourse. When you feel safe throughout foreplay it's easy to penetrate and if you're not worried at penetration time then intercourse is easier. A happy and satisfying sex life is knowing when and where to put your attention. How to do this is explained step-by-step in my Sex Mastery Hard AND in Control program for men.

Those consuming yohimbine lost nearly 30% more fat and experienced 31% greater reductions in body fat percentage compared to those in the placebo group. Neither group reported negative side effects from a twice-daily dosing of 10mg of Yohimbine HCL. These findings indicate that the powerful fat loss effects of yohimbine apply to even the most seasoned athletes with already low levels of body fat.

Did you copy past all that information without research just to get your post count up? WTF! Your mixing the instant Niacin which is the best and the time release niacin which is THE TOXIC version of niacin because some fat ass pussy whiner did not like the flushing. The real Niacin has no significant side effects. If you take to much you feel nauseated and at those levels you are still WAY BELOW what would be considered toxic for your body. Niacin actually makes your erections harder and your penis slightly increases in size. If you are having a hard time getting it up, it's something else. I also strongly advise to take niacin just before bed time as it will lower your stamina. I do not fully understand why it does this. It has something to do with ity regulating the fats in your blood. Niacin is also a sleep aide.


The Enlightenment proved itself to be an intellectual movement in 18th Century Europe that mobilized the power of reason to advance knowledge and reform society. It promoted intellectual transaction and opposed intolerance and abuses by both Church and State. This constituted a challenge to and disparagement of the heavy-handedness of the State. Thus, society was lifted and enlightened.
I never thought i could smile and be in a happy marriage again if not for the help of Dr salato. I got dr salato on his website https://drsalatosolutionte.wixsite.com/drsalato on the internet and i emailed him, and he got back to me with some encouraging words, he got me some herbs which i took for just 5 days and i began to feel the enlargement of my penis, and without surgery. This went on for a little period of about 14 days and to my surprise my wife keeps screaming that she love my big dick
When experiencing difficulty in achieving an erection, it’s important to figure out if you are able to achieve an erection at all or if this happens only when you are with your partner. If you are unable to achieve an erection on your own, this may be more related to a medical and/or physical condition. Examples of this could include heart conditions, neuromuscular disorders, or pelvic pain. To evaluate if this is the cause of your condition, you should follow-up with your physician to examine your cardiovascular, neurological, and musculoskeletal system. From here, they may recommend medications such as Viagra or Cialis, or sometimes a referral to a urologist.
medicines called alpha-blockers such as Hytrin (terazosin
HCl), Flomax (tamsulosin HCl), Cardura (doxazosin
mesylate), Minipress (prazosin HCl), Uroxatral (alfuzosin HCl),
 Jalyn (dutasteride and tamsulosin HCl), or Rapaflo (silodosin).
Alpha-blockers are sometimes prescribed for prostate
problems or high blood pressure. In some patients, the use
of Sildenafil with alpha-blockers can lead to a drop in blood pressure or to fainting
When stimulated by the nerves, the spongy tissue arranges itself in such a way that more blood can be stored in the penis. The veins running through the outer sheath of the penis then compress which stops the blood from leaving the penis. As the blood is stopped from flowing out, the penis fills with blood and stretches within the outer casing, giving an erection.
The concentration of yohimbine in commercial supplements may vary from one manufacturer to another. A chemical analysis conducted on 26 brands of yohimbe supplement shows that nine products contain no yohimbe extract at all, while eight products contain only small amounts of yohimbine — approximately 0.1 to 1 parts per million (ppm), which is significantly low compared to 7,089 ppm yohimbine in an authentic yohimbe bark.3

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.


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.

Yohimbine significantly increased subjective measurements of sexual desire, sexual satisfaction, frequency of sexual contacts, and erection quality during sexual intercourse. Each subject also underwent a sleep study and researchers found that yohimbine also objectively increased the rigidity of erections while sleeping. [12] Yohimbine appears to alleviate both physical and psychological symptoms associated with ED.
Zinc affects different aspects of mammalian reproduction. Testicular disruption, impaired spermatogenesis and subsequent poor semen parameters are found in males with zinc deficiency. Testicular concentration of zinc was lower in male sheep fed with zinc deficient diets. The same animals showed smaller seminiferous tubules and less lumen development than the controls.[1] Similarly variable degrees of maturation arrest in different stages of spermatogenesis with reduced diameter of seminiferous tubules were noted when rats were fed with zinc deficient diets.[2] Zinc deficiency causes a reduction in the structural parameters of seminiferous tubules influences serum levels of testosterone (T) and prolactin (PRL) in rats.[3,4]

Erectile dysfunction can occur as a side effect of medication taken for another health condition. Common culprits are high blood pressure meds, antidepressants, some diuretics, beta-blockers, heart medication, cholesterol meds, antipsychotic drugs, hormone drugs, corticosteroids, chemotherapy, and medication for male pattern baldness, among others.
The number of intromissions in the 5 mg/day group was comparable with controls. On the other hand number of penile thrusting was significantly increased with the same dose. These are indications of unimpaired erectile function due to supplemented zinc. Our observations also confirmed the lack of aberrant sexual behavior which is indicative of uninhibited penile tactile sensations.[15] Sexual behavior may also be changed with motor weaknesses and incoordination.[12] Supplementation with zinc did not impair muscle strength or coordination when tested with bar and bridge tests, indicating that prolongation of ejaculation was not mediated through these mechanisms.
Yohimbe goes by many names depending on how it’s sold. These include Yohimbehe, Yocon, Yohimex, Johime, Aphrodien and Corynine. Do any yohimbe supplements actually work to help treat sexual problems like impotence, or other conditions? Study results have been somewhat mixed. But there’s some evidence that they may help these conditions. It’s especially helpful when combined with other substances that promote better flow and higher energy levels, such as L-arginine. (3)
Our bodies are designed to be active and in motion. By keeping active and engaging in regular aerobic exercise, you increase the blood flow to your muscles, and your penis along the way. One of the most interesting things about increasing your blood flow is that it becomes a signal to your blood vessels to grow and get wider. It benefits your brain, your heart, and your erection. The principle of "use it or lose it" is the best advise one can follow. In fact, if you don't engage in sexual activity at least once or twice a week, it would be beneficial to masturbate. This not only helps with prostate health, but encourages the blood vessels that contribute to your erection to maintain their patency and flow.
