Therefore, scientists concluded that men who frequently visit striptease bars, or like watching erotica or sexual images on the internet, run twice the risk of developing prostate. This disease can be caused by stagnation in the genitals.

When the frustration condition (when erection is not followed by ejaculation) becomes a habit, it leads to a metabolic disorder in genitals which causes venous blood stagnation.

Moreover men who like watching erotic movies often have a lower self-appraisal and experience sexual problems in their relations with women.

Healthy and generally popular cranberry drink is not that harmless either.

If a woman takes oral contraceptives to prevent unplanned pregnancy, she should not take hypericum tincture - a well-known folk medicine for depressions. This herb stimulates breakdown of contraceptives in the liver. As a result comes the unplanned pregnancy.

Any medicine has side effects which “declare themselves” most vividly when an overdose takes place. The overdose can occur when the enzyme responsible for the excretion of the medicine out of the body is inhibited. And even common juice can become such an “inhibitor”.

Another unpleasant thing is that some foods can have an opposite effect - they can “excrete” the medicine out of the body too fast before it had enough time to give you any treatment. We often complain about drugs: they are fake, expensive and don’t cure. But it is quite often our own fault because we take any food without consideration.

The most dangerous things are cocktails made of food and drugs for old people and children!

Studies conducted by David Greening, an obstetrician and endocrinologist from Sydney IVF Company, included 118 men whose sperm cells had a high rate of defective DNA. That rate was 15 to 98% (average of 34%).

The participants of the experiment were asked to ejaculate every day during one week without taking any drugs or changing their life style. After that their sperm was examined again.

The average rate of examined defective DNA was 26% lower.

Meanwhile 80% of men observed a considerable improvement in the quality of their sperm, while the sperm quality of the rest got worse. The experiment also demonstrated that in spite of the fact that the amount of sperm produced during ejaculation went down, the sperm motility improved which provides a better chance for impregnation.

Greening assumed that the quality of sperm improves during regular sexual activity because if the DNA of sperm cells stays in testicular tubules for a long time, it is more exposed to the damaging action of free radicals.

Based on the results of the study, the scientist recommended to couples who want to conceive a child that they should have sex every day within one week before ovulation.

The received data also confirms the result of a research conducted in Israel, in 2003. Back then scientists proved that long sexual abstinence makes sperm quality go worse.

All these physiological reactions are more or less related to physical condition and health. Therefore, sex can be not only satisfying but also useful. And the latter often comes as a result of the former.

Sex can relieve unpleasant cold symptom (fever, body ache, general exhaustion) and promote recovery.

Our moms and grandmas have always told us since childhood that when you catch a cold, you have to “sweat it out” profusely. Chaste relatives suggest covering with many blankets for that purpose and drinking hot tea, which is right. However, wild delightful games in bed are not less effective.

Moreover, studies, conducted by Swiss doctors several years ago, showed that orgasm boosts up immune protection of the body and increases the amount of killer cells in blood. Those cells are called “killer cells” because they act like killers - they find and destroy foreign microorganisms.

There are lots of recipes for hangover, both of folk and medical healing. As a rule sex is not one of them, but it should be.

Hangover is not only a headache, thirst and unpleasant feeling in stomach. Hangover also comes with a depressed state of mind. People suffering from hangovers more often commit suicides.

Apart from the moral reasons (shame for the “night before” and remorse for spoiling “the day after”), the depressed condition has quite physiological causes too. It is caused by the imbalance of hormones which participate in the formation of positive emotions. Sex can help make up for the hormone deficiency providing the body with the previously mentioned endorphin and oxytocin. The latter does not only stimulate muscular contractions but also evokes kind feelings for people, improves social abilities and brings down the level of aggression.

So, if the consequences of the “night before” don’t let you get up, don’t even leave your bed, says Delfi.

As is generally known, it is easier to prevent a disease than to treat it. Active regular sex as any other physical workout makes your heart stronger, burns calories and trains muscles. Perhaps, it is the most pleasant type of fitness which is also absolutely free, as opposed to the gym membership.

In addition to that, thanks to the improvement of local blood circulation, sex “works” as an effective prevention technique for gynecological and urological diseases both in women and men.

However one should not think that it’s only the mechanical and chemical action that matter in sex, and that elevated feelings or at least simple unsophisticated enjoyments do not matter at all. On the contrary, sex “out of a sporting interest” can hardly be useful. And it is not all about morals (this is something one is free to decide for oneself), but the thing is that sex “works” through emotions. If there is no sincere joy, there is no good.

One should not search for sexual adventures only “for health”. If one does not want it or does not have anyone to do it with, it is much simpler and more efficient to do it by other means. But when one wants it and can do it, one should not refuse enjoying this delight because of some minor sickness.

This medicine, primarily known as a stimulant of sexual activity, has not been included in the list of prohibited drugs by any sport organizations. However it is on the register now: world sport leaders are concerned by the fact that during the Olympic games Beijing experienced a sudden boost of sales of Viagra in the Chinese capital and its suburbs.

Before long Gremio’s doctors are going to inform the governing body of the South American Football Confederation about their intention to use Viagra during the team’s training for the Libertadores Cup games. The drug might have a special importance in Bolivia where the highland causes low blood oxygen level in its visitors, providing the home team with a notorious advantage.

Marcelo Ebrard, the mayor of the city, provides an explanation: “sexuality is directly related to the quality of life and happiness.”

Armando Ahued, City Health Secretary, says that the government will distribute certain doses of Viagra, Levitra or Cialis pills after the first of December.

These doses will be distributed among the three centers, which specialize in sexual health of elderly men. Men should obtain a medical certificate before they get drugs.

Ahued asserts that approximately 112 000 men at the age of 70 and older live in the Federal District with a population of 8.7 million people.

About 20 million people live throughout Mexico.

At the same time, saddles with special notches, which are aimed to reduce pressure, can cause even greater harm.

Among 463 examined cyclists more than four per cent underwent erectile dysfunction.

But cyclists who ride a mountain bike on level ground (for instance, in the city) are at most risk.

The owners of bikes with a handle bar below the saddle also suffer from this problem, because such construction brings to higher pressure on inguinal region.

You should also take into account the fact that special saddles do not get the best fit to all men, so they do more harm than good.

Beginners at wheeling are in even greater danger, because they don’t possess necessary skills for proper weight distribution when riding a bicycle.

Professor Joseph Dettori from the Olympic Medical Center in Washington notes that men should not abandon cycling, because it provides an excellent physical activity.

In his turn, the professor promises to develop recommendations for bicycle manufacturers to improve saddle design in a short time.

Argentine scientists discovered that this drug helped hamsters quickly restore their physical condition when changing their usual time cycles. However, this drug works only if flying takes place from the west to the east, rather than vice versa.

Professor Robert Lucas said: “We need to wait for more accurate results of the research to see whether this drug has the same effect on people.” However, the manufacturer believes that Viagra should only be used as a drug that stimulates sexual activity.

Scientists from Stanford University found out that “Viagra” increases body endurance at highlands. Athletes on exercise bicycles took part in the test. Ten of them took a pill “Viagra” and the rest - a placebo. The participants had to overcome the 6-kilometer distance at an altitude of 3900 meters above the sea. After these tests it revealed, that four out of ten participants who took Viagra, improved their results by 39%.

By the way, “Viagra” was approved for the treatment of pulmonary hypertension (high pressure in pulmonary artery).

Sexual dysfunction - is a wide-known side-effect of antidepressants. Nevertheless, the most effective drugs for men are not approved to women, - say the authors of the research in the Journal of the American Medical Association.

Scientists tested “Viagra” on 98 women who have already gotten rid of depression but who were still experiencing sexual problems like a lack of sexual arousal and aches during sexual intercourse.

During eight weeks, women had to take one “Viagra” pill an hour before sexual intercourse. Half of them were given placebo which had no pharmaceutical effect.

Approximately 73% of women who took placebo told that they had no positive effect and only 28% who took “Viagra” said the same.

Cure this unpleasant side-effect among patients gives them an opportunity to continue taking antidepressants, and thus enhance the results of treatment, - wrote the author of the research, George Nuremberg from Medical School in the University of New Mexico.

Scientists say that oxytocin - the love hormone - is produced in a brain during coitus. Besides helping to initiate and bear a child it whips up romantic emotions and strengthens the relationship between a man and a woman. The latest research of the Wisconsin-Madison University shows that hormone secretion not only depends on sexual arousal, but on “Viagra” too.

Oxytocin is produced in a brain of both men and women, especially during orgasm. It appears that protein in “Viagra” have a positive influence on hormone secretion. Because of this protein influence, brain cells produce 3 times more oxytocin than during an ordinary intercourse.

Nevertheless, men shouldn’t forget one thing: hormone secretion can start only during coitus, “Viagra” only strengthens the effect.

“Potency medicine doesn’t provoke spontaneous erection - it only increase organism response to sexual arousal”, - sais professor Meer Jeckson, the head of this research.

Thus, scientists think they found biological explanation to the feeling of love.
