Hearing loss or vision loss. Some men have had sudden loss of hearing or loss of vision after taking one of these medications. However, it isn't clear whether vision or hearing loss was directly caused by taking the medication or by a pre-existing condition. If you're taking an oral erectile dysfunction medication and have sudden loss of hearing or vision, seek prompt medical attention.
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.
Many studies have been conducted on this topic; their results have been challenged by lack of controlled groups and non-randomization. Randomized controlled trials (RCTs) are generally accepted as the most valid method for determining the efficacy of a therapeutic intervention, because the biases associated with other experimental designs can be avoided.Non-randomized controlled trials, can detect associations between an intervention and an outcome. But they cannot rule out the possibility that the association was caused by a third factor linked to both intervention and outcome. Random allocation ensures no systematic differences between intervention groups in factors, known and unknown, that may affect outcome. Randomized controlled trials are the most rigorous way of determining whether a cause-effect relation exists between treatment and outcome and for assessing the cost effectiveness of a treatment (45, 22).

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).
Unfortunately, many of the same factors that brought the Italian Renaissance to an end—among them corruption, wars, and a widespread backlash over secularism and indulgence (leading to the “Bonfire of the Vanities”)—also terminated the “rebirth” in Spain. Chasing heresies became a sport that led to the resurrection of the Inquisition, which unlike its prior appearances operated completely under royal authority, rather than the aegis of the church.
Reduction of the libido index was the major disadvantage that we observed with zinc supplementation. Substances that affect libido usually act centrally and may reduce desire by causing sedation or hormonal disturbances. The role of elevated levels of PRL in serum as an inhibitor of sexual drive and gonadal function is well established. This reduction of sex drive may occur through the modification of activity of dopaminergic neurons in the CNS that are regarded as controlling sexual motivation and function. Our study demonstrated a significant increase of serum PRL level (2.9 to 7.22 ng/dl) within two weeks of supplementation of zinc (5 mg/day). This is a possible explanation for the reduced libido with increasing doses of zinc observed in this study.
Two years ago I took regular Niacine for about a year to lower LDL and increase HDL. I did not want to take Statins because of its side effects. I was being monitored by my Dr. because of the effect on liver enzymes. I took 1.5 gr together with Phytosterols. The treatment was effective and the only side effect were the flushes which I found could be eliminated by having 500 mg at the end of each of the 3 main meals. I stopped treatment for a year or so, but now the Dr. suggested I start taking Niacine. or Statins. I chose Niacine (Nicotine Acid) and started with 500 mgs for 3 days; increased it to 1000 mgs. for 4 more days, until I increased it to 500 mgs x 3 for a total of 1.5 grms/day taking 500 mgms/meal. I started noticing my gradual decrease in libido this time almost inmediately. I do not take any other medicines as such I'm definitely inclined to blame Niacine because I have taken Phytosterols for 3 years and my libido was fine. I'm a senior. Hope this will help!
Besides, niacin’s beneficial effects became more evident when the Hong Kong study researchers excluded those already using statin therapy. If there is an overlapping effect of these two groups of lipid-lowering agents on endothelial function, this would make sense. Also, chronic statin use could lessen the effect of niacin on endothelial function and hence affect improvement in erectile function.
Although they work in similar ways, each oral medication has a slightly different chemical makeup. These minor differences affect the way each medication works, such as how quickly it takes effect and wears off, and the potential side effects. Your doctor will consider these factors as well as any health problems you have and possible interactions with other medications you take.
Researchers at Johns Hopkins University last year looked at 3,400 healthy Americans and found that men who were vitamin D deficient were 32% more likely to have trouble getting it up than those with sufficient levels, even after adjusting for other ED risk factors. In fact, the connection is so common, Walker says D levels are something he always checks in ED patients. Why? The sunshine vitamin is crucial for keeping the endothelial cells that line blood vessels healthy. Without enough of the stuff, blood flow is inhibited, affecting everything from your heart to your hard-on.
No matter what the cause of erectile dysfunction, it is likely to cause feelings of stress and other emotional reactions. It’s also not uncommon for erection problems to cause tension in a relationship, particularly if one or both partners withdraws emotionally and the problem is not talked about. And it’s possible for a man’s renewed ability to have intercourse after a period of no sexual activity to stir up relationship issues.
This is one B team you want to get on pronto: A recent report from Harvard University highlighted a study that has linked low levels of B12 to erectile dysfunction. A causal link hasn’t been nailed down, but the B vitamin is used by every system in the body, particularly in cell metabolism and the production of blood — two essential factors in getting and keeping a quality erection.
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.
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).
But you really do not need any medications like I-Arginine and others to solve your erection problems. Many researches suggest that if you try natural solutions and home remedies rather than going for medications, you will have a healthy and satisfying sex. These vitamins and supplements with surely help in treating your ED (erectile dysfunction) and other penis related problems.
Sildenafil, vardenafil and tadalafil increase the amount of nitric oxide in your body. Your body contains nitric oxide naturally, which is a gas that relaxes blood vessels. Medications to treat erectile dysfunction relax blood vessels in a man’s penis to help obtain and maintain an erection. Some medications that treat high blood pressure, high cholesterol and heart disease also relax your blood vessels. If you take niacin while you also take medications to treat erectile dysfunction, your blood pressure could drop drastically. You could faint or develop other health problems.
Counselling or sex therapy (58% of people find this works for them) –mind-related causes of erectile dysfunction can affect anyone. They are more likely if you experience erectile dysfunction at a younger age. Talking to a counsellor or therapist can help some people overcome erectile dysfunction related to these problems, possibly for good. They can also help you if your erectile dysfunction is causing you stress, as this can make matters worse.
Impotence, or erectile dysfunction (ED), is the inability for a man to sustain an erection long enough for normal, satisfying sexual intercourse. To understand the underlying causes of impotence, it helps to know the basics about how an erection develops, along with potential problems that get in the way. Erections begin in the brain with a thought related to sexual desire. Then a chemical message travels from the brain to the penis. Blood flow to the penis increases as blood vessels leading to the reproductive system relax and allow for increased circulation.
Selenium, found in Brazil nuts, liver and oysters, is a trace mineral that plays an important role in hormone health. You only need a tiny bit for healthy sperm, but a tiny deficiency can be catastrophic for reproductive health. In one study, men who had lower testosterone and were infertile also had significantly lower selenium levels than the fertile group. Supplementing with the mineral improved chances of successful conception by 56 percent. And a second British Journal of Urology study that included 69 infertile men with low levels of the mineral, found selenium supplementation could significantly improve sub-par sperm motility associated with testosterone deficiency.

Erectile dysfunction (ED) is a highly prevalent disease, as well as a major sexual concern for men (Braun et al 2000; Martin-Morales et al 2001; Papaharitou et al 2006). The prevalence of ED is increasing with age. The Massachusetts Male Aging Study (MMAS) demonstrated a 40% prevalence of ED in men aged 40 years that increased to almost 70% in men aged 70 years (Feldman et al 1994). As the proportion of older people in the population increases, it has been estimated that the worldwide prevalence of ED will double from 152 million men in 1995 to 322 million men in 2025 (Aytac et al 1999). ED is also associated with other conditions such as age, smoking, hypertension, heart disease, diabetes, and as a consequence of radical prostatectomy. Cardiovascular disease (CVD) and ED share common risk factors and reflect endothelial dysfunction (Kostis et al 2005). There is an increasing body of evidence that ED is the first sign of CVD in men with free medical history and may present well before CVD with a mean time-interval of even 3 years (Montorsi et al 2003).
In addition, when research has shown a nutrient such as zinc or niacin to improve sexual function, it's usually in people who are deficient in it. So, before you stock up on over-the-counter nutritional supplements for ED, speak with your doctor. He can test you for deficiencies and steer you toward the most effective and safest way to treat your erectile dysfunction.

Research has shown that the same eating patterns that can cause heart attacks due to restricted blood flow in the coronary arteries can also impede blood flow to and within the penis. The blood flow is needed for the penis to become erect. Diets that include very few fruits and vegetables along with lots of fatty, fried, and processed foods can contribute to decreased blood circulation throughout the body.
