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]

Twenty-one men were screened. Two were rejected because they had normal results on nocturnal penile study, and one man was excluded from the study because of a protocol violation. Eighteen men completed the study. The mean age of the men was 60.2 y (range, 34–69 y). The mean duration of erectile dysfunction was 3.1 y (range, 1–10 y). All men were in stable heterosexual relationships. The listed medical risk factors for erectile dysfunction were hypertension in nine men, atherosclerotic cardiovascular disease in seven, single offending medication in seven (mostly beta-blockers), multiple medications in five, diabetes mellitus in four (one with neuropathy), venous leakage in two, and peripheral vascular insufficiency in one.
The Medline (Pubmed) electronic database was searched (from June 1972 to November 2010) for systematic reviews that evaluated the effects of therapeutic exercise on ED. The key words and search terms used to develop the search strategy for each of these databases included: exercise therapy, aerobic exercise, therapeutic exercise, rehabilitation exercise, impotence and erectile dysfunction. In addition, the electronic searches were supplemented by checking the reference lists of any relevant identified articles.
The phrase “penis exercise” actually refers to exercises known as pelvic floor or Kegel exercises, in which a man focuses on strengthening the muscles that control the flow of urine and ejaculation. These exercises are often recommended to men who are recovering from prostate cancer treatment, have problems with ejaculation, or have a hard time holding their urine, but they do not appear to help erectile dysfunction.
Between 2001–2006, one-third of the US population had insufficient amounts of vitamin D, according to the Institute of Medicine. Risk factors for vitamin D deficiency include obesity and high BMI, not enough sun exposure or outdoor activity, having darker skin and suffering from certain from inflammatory conditions like Crohn’s disease. You can get a blood test to find out if you’re vitamin D deficient.

E.D. may just be that early warning sign. Erections depend on blood flow, and blood flow depends on nice, wide-open arteries. Atherosclerosis doesn’t just affect the arteries around your heart; if you have plaque build-up, you are likely to have it all around the arterial system — and the penile artery is one of the smallest arteries you have (no matter what you claim about your size). So if you have atherosclerosis, then the plaque there will be one of the first places where you would notice a decline in blood flow.
These results are remarkable, because it appears that not only can niacin improve short term erectile function in many men, but also can likely help to reverse arterial plaque if a comprehensive program is undertaken.  Of course, neither I nor anyone else knows how safe megadosed niacin is long term, but many experts consider it safe when used under the care of a knowledgeable physician.  You'll have to do your own due diligence.
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.
To evaluate the patients' response clinically in the office, a simple grading system was used.27 The patients were asked about the quality of their erections, which were graded as follows: grade 1, tumescence but no rigidity; grade 2, tumescence with minimal rigidity; grade 3, rigidity sufficient for sexual intercourse; and grade 4, fully rigid erection. At the end of the study, patients were graded as to whether they thought they had improved enough to have satisfactory regular intercourse, which is defined as success in 75% of attempts. The degree of subjective improvement in intercourse was used to classify patients as ‘responders’ vs ‘nonresponders’ in subsequent analyses. A log was kept by the couple of their sexual activity, and it was taken to the clinic for review by the clinical investigator.

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.
