None of the parameters showed a significant difference between controls and the group treated with 1 mg of zinc. The percentage of males who engaged in intromission (% intromitted), was significantly reduced in 10 mg/day zinc group; only three animals showed the particular behavior. Similarly percentage of rats which ended up with ejaculation significantly decreased with the high dose (two out of eight). Libido index of the highest zinc treated group was significantly low compared to controls; (38 % vs. 88 %, P < 0.05). Number of mounts and intromissions was also significantly decreased in the same group; Number of mounts: 1.58 (SEM 3.16) vs. 11.0 (SEM 1.59) and number of intromissions 2.13 (SEM 4.27) vs. 11.0 (SEM 1.59), P < 0.05).
Although not every study has shown that yohimbe can have slimming effects, certain other studies have found positive results. One study found that yohimbine significantly increased mean weight loss in overweight female patients following a low-energy diet. (12) Possible mechanisms of action include: boosting lipolysis (the breakdown of fats and other lipids by releasing fatty acids into the blood) both during and following exercise, regulating insulin secretion, and reducing appetite.

Aerobic exercise — which means "with oxygen" — consists of continuous, repetitive movements that increase your heart rate and get healthy oxygen into all your muscles by increasing blood flow that supports the heart and blood vessels (and in turn, prevents ED). In fact, research suggests that regular aerobic exercise can lower the risk for erectile dysfunction by about 40 percent.
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.
There’s no bedroom bummer quite like having to fly at half mast, but your penis problems are likely more common than you think: As many as 30 million American men suffer from erectile dysfunction, and one in four who seek treatment for ED are actually under the age of 40, according to a study in The Journal of Sexual Medicine. We all know there’s a little blue pill that can fix the failure to launch—but you don’t necessarily have to fill a ‘script to save your stiffy.
Latest research studies highlighted that a daily dose of Vitamin B3 or Niacin brings a drastic improvement in the erectile function of men dealing with the problem of high cholesterol. This result reveals that about 80 men, who consumed Niacin and started the study with either moderate or severe level of erectile dysfunction highlighted a significant improvement in the ability of maintaining an erection.
Over the years, myriad treatments and gadgets have been invented to assist with issues related to erections. They run the gamut from vacuum pumps to constriction bands, surgical implants, male hormone therapy, herbal supplements (ginkgo biloba, saw palmetto, L- arginine, and yohimbe), and even shock-wave therapy. Lifestyle changes include: increasing exercise, decrease smoking, losing weight, and eating healthier. More natural alternative treatments include acupuncture and watermelon juice. In her hilarious and informative book entitled Bonk, researcher Mary Roach explores coupling of science and sex, and dedicates a couple of chapters to in-depth analysis of erectile dysfunction treatments.
I was impressed with the questionnaire to make sure the meds I requested were right for me and the follow up email from the prescribing doctor to see if I needed any support. The meds came promptly, were well packaged and are comfortably in date - I thought they might be very near their sell by date but I was wrong to be suspicious. If I ever need this service again I wouldn't hesitate.
L-arginine. L-arginine is an important amino acid that the body needs to build proteins. Because L-arginine has been shown to improve blood flow, some alternative practitioners have recommended that the supplements be used to treat ED. The Natural Medicines Comprehensive Database, which is a reliable authority on alternative medicines, says L-arginine is possibly effective for treating erectile dysfunction. But Harris warns that "although this supplement could improve blood flow, side effects can be dangerous." L-arginine can cause an allergic reaction or worsen asthma in some people; it can also lower blood pressure.
The appropriate dose of yohimbe depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for yohimbe. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
Ginkgo biloba. Ginkgo is an herb that is used in Chinese medicine that’s thought to improve blood flow. "Any ED treatment that improves blood flow may help," explains Dr. Harris. "An erection is just blood in and blood out." However, the evidence that ginkgo can improve blood flow in ED is limited, and most experts say the jury is still out. In addition, ginkgo can increase the risk for bleeding problems if combined with certain medications, such as warfarin (Coumadin).
As an alpha-2 antagonist, yohimbine promotes sympathetic activity. According to a number of studies, yohimbe can increase blood pressure. This is why it’s useful for things like erectile dysfunction or diabetic nerve problems. Yohimbine is sometimes used to treat low blood pressure and symptoms like dizziness when standing up. It works by dilating blood vessels and acting on the sympathetic nervous system. However, it’s important to point out that increased blood pressure can also be a problem for some people, especially those with existing cardiovascular problems, people taking blood pressure medications, or those who already have high blood pressure.
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.
Three of the randomized studies (25–27) that contributed to the present study data indicated the positive role of both interval and continuous aerobic training in the dual management of both ED and cardiovascular disorders (hypertension and ischemic heart disease ,respectively); this is not surprising because of the arterogenic interrelationship between ED and several cardiovascular disorders. The physiological basis for the therapeutic role of continuous exercise in the management of both ED and some cardiovascular disorders as reported in the present study, could be related to the biochemical, neural and hormonal changes in the blood vessel walls that induce an acute and long-term blood vessel relaxation. The blood vessels might relax after each exercise session because of body warming effects; local production of certain chemicals, such lactic acid and NO; decreases in nerve activity; and changes in certain hormones and their receptors (32, 33). Over time, as the exercise is repeated, there appears to be a growing evidence of a prolonged effect. Thus, chronic (regular, longterm) physical training might reduce basal concentrations of inflammatory markers.
Erectile dysfunction (ED) is one of the most common sexual problems that men deal with. There are a host of different causes of ED that range from nutrient deficiencies to clinical depression. It’s important to talk to a medical professional about ED, in order to determine the cause of the issue before exploring treatment options. That said, erectile dysfunction has been found in recent years to be a symptom of zinc deficiency.
