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.
b) Men With Digestive Disorders.  There are many, many GI disorders that plague modern, urban dwellers:  atrophic gastritis, Crohn's, diverticulitis, enzyme deficiencies, IBS, ulcerative colities and on and on.  All of these can lower vitamin and mineral absoprtion.  Men struggling with these issues may very well benefit from increased amounts of niacin in the diet or possibly with supplementation.
Vidal and her team looked at self-reported physical activity among 300 men, and then categorized them into categories: sedentary, mildly active, moderately active, and highly active. These men also reported their levels of sexual function, including their ability to have an erection and orgasm, as well as the quality and frequency of their erections and overall sexual function.
Derived from the bark of a West African evergreen tree, yohimbe was the go-to ‘script for a wonky willy prior to the advent of wonder drugs like Viagra, Walker says. “Yohimbe enhances sexual performance both by blocking certain neurotransmitters in the brain and by increasing the release of nitric oxide in the cavernosal nerves of the penis,” he explains. And it pairs well with other erection-friendly tablets: A 2010 study in the Iranian Journal of Psychiatry found that a combination of yohimbe and L-arginine successfully helps guys get it up. However, yohimbe also has a handful of side effects, including elevated blood pressure and anxiety, so definitely talk to your doctor before you start on the supp.

Just because a product claims to be natural doesn't mean it's safe. Many herbal remedies and dietary supplements can cause side effects and dangerous interactions when taken with certain medications. Talk to your doctor before you try an alternative treatment for erectile dysfunction — especially if you're taking medications or you have a chronic health problem such as heart disease or diabetes.
There have been only a few  well-controlled studies to test the effects of herbal yohimbe (as opposed to medications) on humans. There’s some evidence that yohimbine has potential to enhance the nitric oxide pathway, helping to bring blood flow to the corpus cavernosum tissue of the penis. It may also stimulate the pelvic nerve ganglia and boost adrenaline supply to nerve endings. It seems to have the most effects overall when combined with other treatments or herbal remedies. (6) One study that evaluated the effects of yohimbe on ED found that those taking the herbal remedy experienced slight benefits compared to a control group that was not taking the supplement.
Alprostadil self-injection. With this method, you use a fine needle to inject alprostadil (Caverject Impulse, Edex) into the base or side of your penis. In some cases, medications generally used for other conditions are used for penile injections on their own or in combination. Examples include papaverine, alprostadil and phentolamine. Often these combination medications are known as bimix (if two medications are included) or trimix (if three are included).
Penile implants - are generally used if physical damage (like an accident) makes the anatomical parts needed for an erection not work. These are inserted by surgery and can provide a permanent treatment choice if others fail to work. The implants can be semi-rigid or inflatable. They can be pretty expensive and are not usually available on the NHS.
In the United States, certain prescription drugs containing yohimbine have been approved since the 1980s. They are labeled Yohimbine hydrochloride (which go by the brand names Aphrodyne or Yocon). Yohimbine medications are prescribed most commonly to treat sexual dysfunction in both men and women caused by a number of factors like aging, hormonal imbalances or side effects of medications.
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.
• Eliminate your bad habits: Bad lifestyle habits may take a toll on your body, making it harder for you to maintain your athletic performance, regulate your weight or treat sexual dysfunction. To keep your body in its best condition, quit your bad habits immediately — eliminate smoking, avoid excessive alcohol intake and cut down your late-night meals.
Once you get checked out for artery blockage and low T, there are things you can do to help treat ED besides taking medications. Yes, Viagra is now available generically (it’s called sildenafil), but it is still expensive, and many men experience side effects, like heart palpitations or blue-ish vision. Here are a few proven natural ways to help improve E.D.
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).
To locate the muscles these exercises engage, try to stop and restart the flow of urine mid-stream. Just do this once, because if you do it too much it can affect the passage of urine. Once you’ve located these muscles, you can tighten and draw the muscles in, feeling them lift upward. Hold for a count of five, then release. It’s recommended that men do 8 to 10 repetitions, resting in between. Ideally, each series of 8 to 10 should be followed by 5 to 10 quick squeezes and releases, and men should work up to doing the whole process four or five times per day for best results.
When it comes to boosting sexual performance, many men will walk all over God’s green earth looking for ways to maintain a good sex life. Luckily men, all you have to do is walk — not run — 2 miles a day. This, along with other healthier lifestyle interventions can help obese men reduce their risk of ED, or even “reverse” current impotence, according to a 2005 study. This comes of importance, since maintaining a trim waistline is a good defense for ED, as men with a 42-inch waist are 50 percent more likely to have ED than those with a 32-inch waist. Getting to a healthy weight and maintaining it is a good strategy for preventing and treating ED.
It is now thought that ED is part of the cardiovascular disease complex related to metabolic syndrome (MS). Although endothelial dysfunction and atherosclerosis are believed to be part of the main mechanisms for ED in patients with MS, other mechanisms account for ED in MS include androgen deficiency, drugs, the veno-occlusive mechanism, etc. Because dyslipidemia is one of the key risk factors for the development of endothelial dysfunction and atherosclerosis in MS patients, there is a close relationship between ED and dyslipidemia.
Also to be considered, patients were not using PDE5 inhibitors during the study period. Therefore it wasn’t determined whether the combined use with niacin can enhance the response of PDE5 inhibitors. Another limitation on the study results was the exclusion of the partner’s assessments. This would help to provide a more comprehensive assessment of the efficacy of niacin.

Associated risks/scrutiny: “A dose of yohimbine that’s too big could drop your blood pressure, cause dizziness, facial flushing and nausea,” warns Fratellone. Yohimbine and yohimbe bark may also increase heart rate and raise blood pressure. “No one should experiment with herbs without talking to their doctor,” reminds Fratellone. “If you’re taking Flomax and you start taking yohimbe, you’re going to dilate your penal vessels and you’ll pee more.” Other potential interactions between yohimbe and other drugs and herbs should be considered. Some of these combinations may be dangerous.

Esposito et al (18), in their randomized study investigated the effect of physical activities on 110 obese subjects. They reported significant effect of physical activities on both body mass index and EF. The physiological rationales underlying this hypothesis are that healthy lifestyle factors are associated with maintenance of good erectile function in men (19); obesity has been positively associated with endothelial dysfunction and increased serum concentrations of vascular inflammatory markers (34, 35); and both endothelial and erectile dysfunction may share some common metabolic and vascular pathways that may be influenced by behavioral-related pathways (19, 36). Obese men with erectile dysfunction had evidence of abnormal endothelial function, which was indicated by reduced blood pressure and platelet aggregation responses to L-arginine and elevated serum concentrations of markers of low-grade inflammation, such as IL-6, IL-8, and CRP. It has been shown that there are significant associations between IEEF score and proxy indicators of elevated body fat, the vascular response to L-arginine, and circulating IL-8 and CRP levels. The association we found between IEEF score and indices of endothelial dysfunction supports the presence of common vascular pathways underlying both conditions in obese men. A disturbance in nitric oxide activity linked to reduced nitric oxide availability could provide a unifying explanation for this association. In particular, in isolated corpus cavernosum strips from patients with erectile dysfunction both neurogenic and endothelium-dependent relaxation is impaired (37).
In the Hong Kong study, the researchers postulated that niacin might be as beneficial as statins on erectile function, and have other related benefits too. Niacin is known to produce a flushing effect (see “Toleration Despite Adversity,” above), which is related to prostaglandin D2 (PGD2) release in the skin. This can lead to vasodilation and concomitant flushing. The production of PGD2 can also occur in macrophages, a type of protective white blood cell. Consequently, when PGD2 production is induced by niacin, it may affect all body tissue, including the cavernosal tissue in the penis. Indeed, PGD2 is one of the potential agents causing the vasodilation and engorgement of cavernosal tissue, thereby leading to erection. Thus, niacin improves erectile function by stimulating the production of PGD2.
Suggested intake: “The problem with yohimbine is that you can’t regulate the amount in a dosage,” says Fratellone. “It all depends on what part of the tree it comes from, how it’s cultivated, how it’s exported, and so on. The amount of extract you get will vary.” FDA researchers analyzed a number of over-the-counter yohimbe bark products. They found that the supplements contained only seven percent or less of the amount of yohimbine that would be found in actual yohimbe bark, which suggests that they contained little or no yohimbe. However, the prescription form of yohimbine is strictly regulated by the FDA. It is approved only for the treatment of impotence, and is available in tablets and capsules. For erectile dysfunction, 5.4 to 10 milligrams three times daily has been studied and regarded as generally safe.
Taking one of these tablets will not automatically produce an erection. Sexual stimulation is needed first to cause the release of nitric oxide from your penile nerves. These medications amplify that signal, allowing some men to function normally. Oral erectile dysfunction medications are not aphrodisiacs, will not cause excitement and are not needed in men who get normal erections.

Pelvic floor exercises are actually good as they can enhance the strength of the pelvic floor muscles. These exercises are commonly called Kegel exercises. These are the types of exercises that women usually perform in order to regain their muscle tone right after childbirth. They are also known to enhance urinary continence and overall male sexual health.
Research has shown that the same eating patterns that can cause heart attacks due to restricted blood flow in the coronary arteries can also impede blood flow to and within the penis. The blood flow is needed for the penis to become erect. Diets that include very few fruits and vegetables along with lots of fatty, fried, and processed foods can contribute to decreased blood circulation throughout the body.
Prostate problems are most common in older men, but it’s never too early to start looking after your prostate! Problems such as BPH (enlarged prostate) and prostatitis can cause unpleasant symptoms such as frequent urination, weak urine stream, difficulty urinating and sudden urges to urinate, which can really get in the way of daily life and interrupt sleep.
In the analysis of the study, the niacin group showed a significant increase in both IIEF-Q3 scores and IIEF-Q4 scores compared to the initial baseline values. While the placebo group also showed a significant increase in IIEF-Q3 scores (high hopes, no doubt), it did not for IIEF-Q4 scores. In other words, the “placebo effect” did not extend to maintaining erections. Also, 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 and 1.03, respectively) and IIEF-Q4 scores (0.56 and 0.84, respectively) compared with baseline values. These results were not significantly increased for the placebo group.
But you really do not need any medications like I-Arginine and others to solve your erection problems. Many researches suggest that if you try natural solutions and home remedies rather than going for medications, you will have a healthy and satisfying sex. These vitamins and supplements with surely  help in treating  your ED (erectile dysfunction) and other penis related problems.
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.

The herb is particularly effective for those whose willy woes are based on other medications: An older study from the University of California found ginkgo biloba is 76% effective in treating sexual dysfunction caused by antidepressants. “Gingko helps counteract sexual dysfunction caused by certain antidepressants called SSRIs by blocking serotonin activity in the erectile centers of the brain, ultimately leading to better synthesis and bioavailability of nitric oxide,” Walker explains.


Some medical self-help books make niacin sound like a panacea for health-conscious people with rising cholesterol levels and shrinking budgets. Because this B vitamin is cheap and sold over-the-counter at drug and health food stores, people see no reason to check with the doctor before tossing back a handful of pills. What they may not know is that the high doses (1,500-3,000 mg) needed to lower cholesterol levels can cause serious complications. (As a dietary supplement, 10-20 mg is usually recommended). To add to the confusion, niacin comes in two forms: immediate- and sustained-release preparations.

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!


Usually there will not be a specific treatment that will lead to the improvement of erectile dysfunction. However, there are treatments that will allow erections to happen and can be used to allow sexual activity to take place. There are three main types of treatments: non-invasive treatments such as tablet medicines and external devices (e.g. vacuum device); penile injections; or for men who have not had success with other treatments, surgery may be an option.
Testosterone levels generally decrease as an individual ages. This is normal and natural, but it can lead to erectile problems for some people because androgenic hormones such as testosterone play an important part in regulating the function of tissues in the penis and testicles. One study found that supplementing with testosterone gel improved both the libido and erectile function of participants with low testosterone between the ages of 32 and 84.
Yohimbine may have certain fat-burning abilities and work even better while someone is fasting. (11) Given that yohimbine can act as a mild stimulant, researchers have looked at whether it can help increase energy levels in those looking to become more active, or whether it has positive effects on reducing appetite, regulating blood sugar levels, or promoting growth of muscle mass that can then help with weight loss.
Few men want to talk about their inability to get or maintain an erection, however, erectile dysfunction can have a profound impact on relationships and self-esteem. Fortunately, trouble in the bedroom doesn't necessarily mean you're dealing with erectile dysfunction. Most men will have problems with an erection at some point in their sexual history. But one bad day in the bedroom doesn't mean major sexual health problems. So how can you know if you're dealing with erectile dysfunction?
The following parameters were computed using the observed behavioral measures. Copulatory efficiency (proportion of mounts resulting in vaginal penetration relative to the total number of mounts), intromission ratio (number of intromissions/number of intromissions + number of mounts) and intercopulatory intervals (average time between intromissions).[8]
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.
If other options sound boring, maybe you should consider a fun, revved-up option like salsa dancing. You and your partner can lose yourself in the music, and it’s an intense exercise that engages the senses, combining cardio, balance, and coordination. Plus salsa dancing is great for keeping weight under control because it burns a lot of calories. Furthermore, it’s an activity that can build self-confidence, and if you’re single, the classes can be terrific for meeting new people. Regular exercise doesn’t have to be drudgery, and there are many types of dance classes that can seriously improve fitness and help you address erectile dysfunction.
A study of 23 individuals found that a dose of 0.4mg/kg of yohimbine not only increased norepinephrine in the blood, blood pressure, and heart rate, but it also increases impulsive response rates. These response rates are measured by the number of impulsive errors, response biases, and reaction times on an immediate memory task. [10] While yohimbine may improve your reaction time it may also encourage you to act irrationally.
Often when we start to look outside of mainstream medicine for alternative protocols to heal our health issues we replace one pill-taking protocol with another. The prescription drugs are replaced with a long list of supplements. Supplements alone, without any other lifestyle changes, will have some impact, but it will be nowhere near what they can achieve when working in a body supported with a healthy way of life.
Due to its ability to inhibit actions of the sympathetic nervous system, yohimbe can help to bring blood pressure levels back to balance. This is is why it’s used to sometimes increase blood flow, such as to tissues of the reproductive organs.  Or, also why it’s used to treat hypotension (abnormally low blood pressure). It may also be helpful for stimulating nerves and treating fatigue or symptoms of depression.
Yohimbe has been shown to be an alpha-adrenoceptor blocker. This action reduces the effects of hormones that increase the constriction of blood vessels as a person ages. Yohimbe also increases production of norepinephrine, which plays a role in achieving erection during sexual arousal. Yohimbe increases the amount of adrenaline that reaches the nerve endings, enhancing sexual sensations and allowing for a more satisfying sexual experience. Yohimbe has been shown to support sexual longevity.

Have you heard about the famous Kegel exercises women often turn to for help? Well, these exercises are not for women only. You can perform them also and get the same beneficial effects as women. Kegel exercises for men are often recommended by many doctors to be used in the treatment of erectile dysfunction. Kegel exercises will strengthen your pelvic floor muscles. In order to perform these exercises, you will need to locate your pelvic floor muscles (to do that you will need to stop the process of urinating a couple of times) and squeeze them a couple of times. Start performing these exercises a couple of times a day and see the results for yourself.
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.
Two years ago I took regular Niacine for about a year to lower LDL and increase HDL. I did not want to take Statins because of its side effects. I was being monitored by my Dr. because of the effect on liver enzymes. I took 1.5 gr together with Phytosterols. The treatment was effective and the only side effect were the flushes which I found could be eliminated by having 500 mg at the end of each of the 3 main meals. I stopped treatment for a year or so, but now the Dr. suggested I start taking Niacine. or Statins. I chose Niacine (Nicotine Acid) and started with 500 mgs for 3 days; increased it to 1000 mgs. for 4 more days, until I increased it to 500 mgs x 3 for a total of 1.5 grms/day taking 500 mgms/meal. I started noticing my gradual decrease in libido this time almost inmediately. I do not take any other medicines as such I'm definitely inclined to blame Niacine because I have taken Phytosterols for 3 years and my libido was fine. I'm a senior. Hope this will help!

After two hours of zinc treatment, male rats were individually caged and kept for 15 minutes for adaptation. One estrous (receptive) and one diestrous (nonreceptive) female were introduced to each cage and the duration of physical contact with each female was recorded for 15 minutes. Partner preference index (PPI) was calculated as the difference between the time spent with estrous female and diestrous female. Positive indices indicate their positive sexual interest.[12]

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 rare cases, the drug Viagra ® can cause blue-green shading to vision that lasts for a short time. In rare cases, the drug Cialis® can cause or increase back pain or aching muscles in the back. In most cases, the side effects are linked to PDE5 inhibitor effects on other tissues in the body, meaning they are working to increase blood flow to your penis and at the same time impacting other vascular tissues in your body. These are not ‘allergic reactions'.
Exercise helps to maintain blood circulation to this region and strengthens your heart so it can pump blood more effectively when at rest. As you exercise, your blood vessels dilate and more capillaries open so that blood can effectively be moved to where it is needed. Much of this blood is routed via the genital region, opening the network of vessels which feed the penis. The region will receive an improved circulation as a result even when your body is at rest, and increased blood flow to the skin itself brings the added benefit of greater sensitivity.
It promotes the formation of red blood cells, enhances cellular metabolism, supports brain function, improves sexual function in men, and contributes to the healthy sperm production. This is because vitamin B12 is required for the formation and duplication of DNA which, in turn, is responsible for the healthy sperm production. And vitamin B12 deficiency affects genetic material the sperm carries.
On the other hand, high zinc levels have negative effects on sperm quality. Excessive zinc intake in mice have indicated a negative effect of increasing doses of zinc on sperm count and motility.[5] Although there have been studies focusing on various aspects of zinc related reproductive functions, studies on zinc related sexual behavioral aspects have received scant attention. In one study, intranasal irrigation with zinc sulphate has been reported to completely abolish the sexual behavior of male rats.[6]

A study published in May 2014 in The Journal of Sexual Medicine found that some men can reverse erectile dysfunction with healthy lifestyle changes, such as exercise, weight loss, a varied diet, and good sleep. The Australian researchers also showed that even if erectile dysfunction medication is required, it's likely to be more effective if you implement these healthy lifestyle changes.


There have been only a few  well-controlled studies to test the effects of herbal yohimbe (as opposed to medications) on humans. There’s some evidence that yohimbine has potential to enhance the nitric oxide pathway, helping to bring blood flow to the corpus cavernosum tissue of the penis. It may also stimulate the pelvic nerve ganglia and boost adrenaline supply to nerve endings. It seems to have the most effects overall when combined with other treatments or herbal remedies. (6) One study that evaluated the effects of yohimbe on ED found that those taking the herbal remedy experienced slight benefits compared to a control group that was not taking the supplement.


A cold slice of watermelon can do more than just satisfy thirst and hunger during the warm summer months; it can help with bedroom satisfaction. Citrulline, the amino acid found in high concentrations of watermelon, is found to improve blood flow to the penis. A 2011 study revealed men who suffered from mild to moderate ED and took L-citrulline supplementation showed an improvement with their erectile function and were very satisfied. Natural watermelon juice, or “nature’s Viagra,” can also be easier on the stomach, since taking pills like Viagra can cause nausea and diarrhea.
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.
What are the alternatives to viagra? Erectile dysfunction, when a man cannot achieve or maintain an erection, is a common condition that causes much distress. Viagra is just one of several drug treatments that can help relieve the problem. Other methods and treatments can help, too, including alternative herbal remedies that people may wish to try.

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)

It’s hard to concentrate on what’s happening in the bedroom when you’re thinking about problems at work. For many men, it’s psychological issues like anxiety rather than physical ones that contribute to E.D. Chronic stress has also been linked to heart disease, high blood pressure, depression, and more. Find a way of blowing off steam that works for you (I like exercise and meditation) and stick to it.
