Much of the evidence shows high rates of vitamin D deficiency in patients with erectile dysfunction. In fact, one study of 3,400 participants found that men with vitamin D deficiency were 32% more likely to have trouble with erections when all other risk factors were controlled for. It’s a little on the nose that you need vitamin D for your “D,” but hey—science can be funny too.
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)
Researchers in London set out to find out if the claims about Yohimbe were true. Could the bark of a tree actually increase libido and improve impotence? They performed a double-blind trial using yohimbine for the treatment of erection inadequacy. Men, aged 18-70 years, seeking help for the secondary erection inadequacy for 6 months or longer, took part in the trial. None of the participants had any serious psychiatric disease, hypertension or liver insufficiency. Half of the men were given 5.4mg of yohimbine, the other half a placebo, for 8 weeks. Patients were assessed in 4-week intervals. After 8 weeks of treatment, 37 percent said they had good erections, as compared to only 13% in the placebo group. After the 8-week treatment, the placebo group was given the yohimbine as well, results for improved stimulated erection after the second 8-week trial increased to a total of 42 percent overall.
A physical exam checks your total health. Examination focusing on your genitals (penis and testicles) is often done to check for ED. Based on your age and risk factors, the exam may also focus on your heart and blood system: heart, peripheral pulses and blood pressure. Based on your age and family history your doctor may do a rectal exam to check the prostate. These tests are not painful. Most patients do not need a lot of testing before starting treatment.
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.
