Motivated by philosophers that included John Locke (the most influential of Enlightenment thinkers), Voltaire, Newton, and Leibniz, ruling princes throughout Europe endorsed and fostered the intelligentsia of the Enlightenment. Some of these rulers even attempted to apply the ideas of the enlightenment to government. When grasped by “natural aristocrats,” the Enlightenment was particularly successful in America where it influenced Benjamin Franklin and Thomas Jefferson, among many others, and fueled the fires that led to the American Revolution, the Declaration of Independence, and the creation of the United States.

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.
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.
Data from the Florida Sexual History Questionnaire collected at each time period (baseline, 5.4 mg tid and 10.8 mg tid) are presented in Table 6. Three patients (two responders and one nonresponder) did not complete the entire questionnaire for each study period and were excluded from the analyses. Thus, data in the table and statistical analyses are based on the responses of seven responders and eight nonresponders.
Obesity is a state of chronic oxidative stress and inflammation (38). The increased oxidative stress associated with obesity may increase free radical formation, which could quench and deactivate nitric oxide, reducing its availability for target cells. Weight loss programs with dietary modifications and increased physical activity may lead to reduced oxidative stress associated with improved nitric oxide availability (39). As impaired nitric oxide activity appears to play an important role in the pathogenesis of erectile dysfunction (40), improved nitric oxide availability associated with weight loss may be implicated in the amelioration of erectile function in our series of obese men. A reduced CRP level due to sustained lifestyle changes may have contributed to amelioration of erectile function after treatment. Levels of CRP correlate significantly with reduced nitric oxide availability (41) and increasing severity of penile vascular disease as measured by penile Doppler (42). Moreover, consistent findings support a predictive role of CRP and IL-6 for cardiovascular events in different populations (43), while IL-8 is a potent chemoattractant (44).
For Men: Soy is terrible for the male sex drive as the phytoestrogens build up to unnatural levels much too quickly. In fact, an ex boyfriend and I experimented with this when he decided to become vegan. He ate and drank soy products for a month and by the end of that time he had zero libido. Within two weeks of stopping all soy, he was back to normal.

Alprostadil is injected into the side of penis with a very fine needle. It's of great value to have the first shot in the doctor's office before doing this on your own. Self-injection lessons should be given in your doctor's office by an experienced professional. The success rate for getting an erection firm enough to have sex is as high as 85% with this treatment. Many men who do not respond to oral PDE5 inhibitors can be ‘rescued' with ICI.
A study from 1990 (eight years before Viagra was introduced) found that sedentary but otherwise healthy middle-aged men who started an intense aerobic exercise program reported higher levels of sexual intimacy, and more reliable sexual function. Men in the study who started a walking program also experienced improvements, though not as dramatic. But the bottom line is, improved physical fitness often improves sexual functioning and satisfaction. Here are 5 exercises that can help with erectile dysfunction.

The response to yohimbine did not vary with patient age; the responders were 60.3 y of age vs 60.0 for the nonresponders (Table 4; P=0.106). The number of medical risk factors was slightly higher in the nonresponders (2.3 per person) compared with the responders (1.8 per person), but this difference was not significant (P=0.346). Documenting the quality of the men's erections in the office with a simple grading system showed a significant difference at the end of the study between responders and nonresponders. For the responders, the value was 3.0 compared with 1.9 for the nonresponders (P<0.001). This result correlated with the overall sexual satisfaction of patients who stated whether or not they were able to engage in regular sexual intercourse.


Poor sleep patterns can be a contributing factor for erectile dysfunction, Mucher says. One review published in the journal Brain Research emphasized the intricate relationship between the level of sex hormones like testosterone, sexual function, and sleep, noting that testosterone levels increase with improved sleep, and lower levels are associated with sexual dysfunction. Hormone secretion is controlled by the body’s internal clock, and sleep patterns likely help the body determine when to release certain hormones. 
Participants in this study gradually increased their daily intake of niacin from 250 mg to 3,000 mg over 36 weeks. Nine of the 23 people who were taking immediate-release niacin withdrew from the study early because of facial flushing, fatigue, or skin discoloration. Eighteen of the 23 who were taking 3,000 mg daily of sustained-release niacin dropped out due to upset stomachs, fatigue, or abnormal liver function tests. All of these side effects disappeared once the participants stopped taking the vitamin. Additional cause for concern comes from other reports suggesting that high doses of sustained-release niacin can cause jaundice and liver failure.

The main surgical treatment of ED involves insertion of a penile implant (also called penile prostheses). Because penile vascular surgery is not recommended for aging males who have failed oral PDE5 inhibitors, ICI or IU therapies, implants are the next step for these patients. Although placement of a penile implant is a surgery which carries risks, they have the highest rates of success and satisfaction among ED treatment options.
