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]
Not only will regular exercise burn calories and lower stress, it may lower your risk of ED. Before you start working out, check with your doctor about the best program for you. Think of exercises you're likely to enjoy and will want to continue on a daily basis, whether it's 30 minutes in the morning on a stationary bike while watching the news, a kick-boxing class, or a brisk after-dinner walk around the neighborhood with a friend.
What's to know about erectile dysfunction? Erectile dysfunction (ED) is a condition in which a man regularly finds it difficult to get or keep a firm erection. ED can be caused by psychological, physical, and medical reasons. This article looks at many of the causes, symptoms, and treatment options, which include medication, surgery, exercise, and diet.

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.
Using the protocol of a clinical randomized placebo-controlled parallel-group trial, the study also took place at the University of Hong Kong. One hundred sixty male patients with ED and dyslipidemia were randomized into two groups receiving either up to 1,500 mg of oral niacin daily or placebo for 12 weeks. Using questions from the International Index of Erectile Function (IIEF, particularly questions Q3 and Q4), the primary outcome was improvement in erectile function. Q3 ranked “frequency of penetration,” while Q4 ranked “frequency of maintained erections after penetration.” Other outcome measurements included the total IIEF score, IIEF-erectile function domain, and Sexual Health Inventory for Men (SHIM) score.
Hypercholesterolemia (high cholesterol) is one of the main risk factors in the development of atherosclerosis, a condition that with the development of statins over the last 20 years has become more treatable, but not without consequences. Statins have been shown to reduce the incidence of cardiovascular events by 25–40%, yet this reduction is no big deal, especially considering that many patients need additional therapy to reach more optimal lipid levels and prevent cardiovascular events.
A noticing fact is that each of these men had problems of lipid levels and high levels of cholesterol. According to the author Dr. Chi-Fai in Hong Kong, "Niacin or Vitamin B3 is one among the old erectile dysfunction drugs and medical experts have documented its safety in well manner. Because of this, we should consider it as a simple and an easy way to bring improvements in the men's erectile function."
Because cholesterol is a building block for testosterone, drugs that interfere with cholesterol production can lower levels of this hormone (Journal of Sexual Medicine, April, 2010). French and Dutch researchers have reported that decreased libido and erectile dysfunction may be associated with statin-type drugs (British Journal of Clinical Pharmacology, Sept. 2004; Drug Safety, July, 2009).
Most studies related to male infertility show a clear concise relationship between zinc and ed. During a study some young men were given a diet which included very little amounts of zinc and thus they developed a zinc deficiency. When testosterone levels were measured after 20 weeks of low-zinc diet it was found that the level of the hormone had drastically reduced. The study also found that in elderly men, with an increase in the uptake of zinc, testosterone levels nearly doubled.
Zinc is a trace metallic element that occurs naturally in the earth. Certain vegetables, meats, and seafood have more zinc content than others. This makes it fairly easy to obtain zinc through a varied diet. An extreme zinc deficiency is rare in the United States, as most people get some zinc through the foods that they eat. However, when levels of zinc fall below the recommended threshold, problems begin.
