Viagra is basically used as a treatment for erectile dysfunction. Originally, this drug was developed for heart problems and high blood pressure, but it was later discovered that it can treat male impotence (aka erectile dysfunction), which made this medication very popular and in many times controversial.

The pill works by helping blood vessels to relax allowing blood to flow more easily. Because blood flow to the penis plays major part in achieving an erection. Enhancing blood flow to the penis and genital area will help men get firmer and stronger erections. Viagra not only improves blood flow to the genitals, but throughout the whole body as well. The more blood flowing through your body’s vessels and arteries, the more oxygen delivered to different parts of the body, the more energy you produce and the better you perform.

On the other hand, some experts disagree that Viagra can help athletes do better on the field. Anyway, the World Anti-Doping Agency is studying the effects of Viagra in athletes, which may possibly result in banning this drug.

One thing is for sure, Viagra will definitely “take part” in the Beijing 2008 Olympics.

Other similar drugs like Cialis and Levitra are said to have the same effects on athletes, but no results have been clinically proven yet.

98 women were involved in the study, which was published in the Journal of the American Medical Association. All of those women experienced sexual dysfunction as a side effect of antidepressants. 72 percent of the women involved in the study, who took Viagra pills, reported improvements in their sexual functions. The most significant gain those women have reported was improved ability to reach satisfactory orgasms. Other improvements included enhanced sexual arousal, enjoyment and desire.

Viagra may help improve the sexual ability and treat sexual dysfunction cased by antidepressants in women, but all other studies and researches made/funded by Pfizer didn’t conclude any remarkable effects of Viagra on women in general.

Anyway, if new studies can prove that Viagra also works for women, I think Pfizer will have to change the color of the pill. Maybe it should become the half blue, half pink pill! In fact, you can save yourself some money if you buy 100 mg tablets and cut them in half; you take the blue half and your wife takes the pink one, and then enjoy fireworks in bed. JK!

Yes, don’t be surprised! Researches have shown that watermelon is rich with an amino acid called citrulline, which helps relaxe blood vessels improving blood flow to the heart, penis and throughout the body in general. This is essentially what Viagra and other erectile dysfunction (ED) drugs do.

The big question now is: how much watermelon is equivalent to one Viagra pill?

If that amount costs lower than $10 USD (the normal price of one “brand” Viagra pill), then watermelon could be a cheap, natural alternative to Viagra and it may become men’s favorite diet food. It helps that 92% of watermelon’s content is water (that’s why it’s called “watermelon”), also two cups of watermelon have only about 100 calories, and in addition to that it has low fat and no cholesterol.

But scientists don’t know yet how much watermelon you’ll need to get effective results in treating erectile dysfunction. Researches are yet to provide a definitive answer on whether watermelon could be an effective natural alternative to ED prescription drugs or not.

On the other hand, some scientists and experts think that it’s ridiculous to say that watermelon is a “natural Viagra”. They argue that even if watermelon could help treat ED, it’d require a lot of watermelon to do so which is not a practical solution to the problem.

The generic name of Viagra is Sildenafil Citrate. Viagra is a little blue pill that starts working within 30 minutes (lees or more) and lasts for about 4 hours. Viagra tablets come in three strengths (dosage): 25 mg, 50 mg, and 100 mg.

Cialis (generic name: Tadalafil) is better known as the weekend pill because it can last up to 36 hours of hardness! The strengths of Cialis tablets are: 5 mg, 10 mg, and 20 mg.

Levitra has the generic name Vardenafil. Levitra doses come in four strengths: 2.5 mg, 5 mg, 10 mg, and 20 mg with an effect that can last for approximately 4 hours.

These three drugs work by the same means and they have almost similar side effects, of which the most common are headache and facial flushing.

Follow your doctor’s directions as described in your prescription when taking any of these drugs and seek immediate medical attention if you experience any unusual side effects.

It’s a bad habit that young men who don’t have ED are taking Viagra frequently in the hope of getting the most out of each sex session. An interesting article discusses this issue on this page.

Age is not the main cause of impotence. Impotence or ED can be caused due to other medical conditions, for example Hypertension, Diabetes, Atherosclerosis, and other diseases may cause erectile dysfunction.
Other causes of erectile dysfunction include: smoking, drinking alcohol, prostate surgery, kidney or liver problems, anxiety, depression, and others.

If you are taking other certain medicines/drugs, they may be the cause of erectile dysfunction (Ask your doctor about this).

In order to get a firm erection you have to be both physically and mentally relaxed, you and your partner as well. If you are having troubles in your relationship with your partner it may affect your ability to maintain firm erections during sexual activity. Always talk openly and honestly to your partner about any problems in your relationship and try to work things out.

Don’t be shy to ask for a doctor’s help/consultation if you have, or if you think you have, erectile dysfunction. There’s nothing to be ashamed of and remember that there are more men than you can imagine who have the same health problem.

Always follow the instructions that your physician gives you as he/she knows more about your specific health condition. Here are some general guidelines just for informational purposes:

If you are taking Viagra to treat impotence (erectile dysfunction), your physician may ask you to start on an average dose of Viagra (25-mg or 50-mg) and then increase or decrease your dose after you see how your body responds to the medication.

You should take your Viagra tab (most people prefer to take the 50 mg tabs or they buy 100 mg pills and divide them into 2 tablets) about one hour before sexual activity. You can also try to take it half an hour to three hours before sexual activity and see what works best for you and your partner.

You should not take Viagra pills more than one time every 24 hours or so. Also, your physician may ask you to take Viagra less often if you’re on other certain drugs or if your health condition requires so.

You can take Viagra on an empty stomach (with a glass of water) or after having a low-fat meal. This should only control how fast the pill starts to work. High-fat meals may delay the effect of Viagra.

You should see your physician if you experience uncommon side effects or if Viagra is not working for you as supposed to be.

In order to buy Viagra or Cialis you need to fill a prescription and so you do not endanger your health. You should not take Viagra if you’re on other medicines/drugs that contain nitrates. The effects of Viagra should last for about 4 hours, and about 24 to 36 hours for Cialis. If the effects/erection last for a considerably longer time or if you experience any unusual side effects you should immediately seek medical help.

If you are going to order Viagra or Cialis from an online pharmacy make sure you order it from a good pharmacy/drugstore. A good online pharmacy is the one that asks you for a prescription and other medical information related to your condition.

Viagra has only the following strengths: 25, 50, and 100 mg.
Cialis has only the following strengths: 5, 10, and 20 mg.

You should NOT buy Viagra/Cialis tablets online with strengths other than those mentioned above.
