Guarana & Impotence



Guarana is an herb that contains caffeine. It is used in some energy drinks, and also as an herbal remedy to help with weight loss, migraines and fatigue and to improve mental and sexual function. However, guarana can also cause certain side effects and it is not safe for everyone to use.

Impotence

Impotence, also called erectile dysfunction, is defined as not being able to sustain an erection firm enough to have sex. Many factors can increase your risk for impotence, including obesity, diabetes, high blood pressure, alcoholism, some prescription medications, multiple sclerosis, Parkinson's disease, heart disease, low testosterone, depression, fatigue, stress and tobacco use.


Guarana and Impotence

The effect of guarana on impotence is not clear. A study published in April 2008 in the "Journal of Andrology" found that erectile function in diabetic rats was improved by caffeine supplementation. However, another journal article published in December 2007 in "Evidence-based Complementary and Alternative Medicine," notes that consuming large amounts of guarana may cause impotence. Perhaps this is due its potential to increase blood pressure.

Side Effects and Safety

Guarana can cause allergic reactions and side effects including constipation, diarrhea, loss of appetite, nervousness, upset stomach, heartburn, irregular heartbeat, headache, sleeplessness and chest pain. If you have high blood pressure, heart problems, kidney disease, an anxiety disorder or an overactive thyroid you should not take guarana. Guarana can also cause withdrawal symptoms if you stop consuming it suddenly, similar to those caused by caffeine.

Considerations

Speak with your doctor before taking guarana to make sure it is safe for you. Do not self-treat your impotence with guarana, or use guarana in place of the treatment prescribed by your doctor. The evidence on the benefits of guarana for impotence is preliminary and conflicting, so it is better to use conventional treatments for this condition.

How Guys Might Increase Fertility

Here’s an odd pairing for you: what do your sperm and National Lampoon’s Vacation , that cult hit from way back in 1983 have in common? Never seen it? I’ll summarize it for you. An all-American family from Chicago, quarterbacked by determined, yet dim-witted Chevy Chase (sorry Clark, love ya man) drives across the western United States with their intended destination of Walley World – a knock-off for Disneyland, where good old Dad swears his family will have a rewarding vacation that will bring them together. Well, it wouldn’t be a comedy if things didn’t go crazy stupid along the way now, would it? And the Griswolds’ journey was, as you’d imagine, tumultuous, hair-raising, completely off course and, in hindsight, hilarious. Now how does this relate to your swimmers?

If your sperm resembles a clunky old station wagon, that doesn’t qualify as
