Cycling & Biking can affect your SEX LIFE, reduce sperm quantity

NEW YORK (Reuters Health) – For most men, exercise appears to have no relationship to either the quality or quantity of sperm, according to U.S. researchers.

NUGGET : But they found one exception: Men who biked for at least five hours per week had fewer and less active sperm than couch potatoes.

“It is likely that most forms of exercise have no effect on semen quality and that only certain subtypes of activity, and/or those performed at higher intensity levels, have an effect,” study author Dr. Lauren Wise at Boston University told Reuters Health in an e-mail.

Previous research has suggested competitive athletes may have issues with their sperm. The new report, published in the journal Fertility and Sterility, looked at the relationship between sperm health and exercise in the average man.

The researchers focused on more than 2,200 men who provided semen samples to three fertility clinics, and answered questions about their general health and physical activity.

To eliminate the influence of additional factors that could affect sperm health independent of exercise, the authors used statistical tools to remove the influence of taking multivitamins, body weight, blood pressure, choice of underwear, and others.

Looking specifically at exercise, they found that men who exercised regularly — even vigorously — were no more likely to have problems with the quality or quantity of their sperm than men who never exercised.

However, when Wise and her team looked at specific types of exercise, they saw that men who said they spent at least five hours per week biking were twice as likely to have both a low sperm count, and relatively few sperm with healthy movement.

Among men who did not get regular exercise, 23 percent had low sperm counts — but so did more than 31 percent of those who biked for at least five hours per week. And nearly 40 percent of frequent bikers had low numbers of sperm with healthy movement, versus only 27 percent of men who didn’t exercise.

Previous research looking at competitive athletes has linked biking to genital or urinary problems and poor semen quality, Wise explained.

“However, we were uncertain whether we would find an association among a sample of men engaged in more moderate levels of physical activity,” she said. It’s possible that trauma or temperature increases in the scrotum may explain the relationship between biking and semen health, “but more research is needed to investigate these mechanisms further.”

It’s also too early to say that regular biking caused the sperm problems, Wise cautioned. “More studies are needed to replicate our findings before they can be considered causal.”

For instance, it’s possible the men included in the study may not be representative of the general population, since they were all attending a fertility clinic and therefore are more likely to have problems with their sperm, Wise said. Their physical activity may not differ from that of other men, however, so it is difficult to say how the results might change when looking at men who haven’t been to a fertility clinic, she noted.

Dark Chocolate is healthier than green tea. Improve Sex life, Boost immune system,improved digestion…

NUGGET: Daily consumptions of 100 grams amount of dark chocolate, can have important health benefits.

Flavonoid is found to be a healthy ingredients found in chocolate. It can be found in both processed chocolate and cocoa, raw and evern dairy products.

This flavonoid contained in dark chocolate,similar to those of green tea, has long been used by traditional healers as a medicine and healing remedy.

base on the results of these some research studies into the possible health benefits of flavonoid, the antioxidants contained in dark chocolate may have the following important health benefits:

  • The potential to lower blood pressure
  • Improved blood circulation
  • Lower levels of heart disease
  • Improved function of the cells which line the blood vessels
  • The ability to defend the body against the destructive molecules known as free radicals. These free radicals are thought to help trigger serious diseases such as heart disease, stroke and even some forms of cancer.
  • Improved digestion
  • boost the immune system
  • help prevent heart disease and other chronic problems.
  • good source of magnesium and copper
  • reduce the amount of LDL(bad) cholesterol in the body by 10%.
  • improve the congeniality and sexuality
  • believe to cure malarial infections.

Surprising, this antioxidants found in most dark chocolate can be used to treat patients suffering from anemia, kidney stones and poor appetite, adding even more to the health benefits of this delicious food.

At the same time, while considering the possible health benefits, it is important to keep in mind that it contains two different kinds of flavonoids – catechin and epicatechins.

Catechins are known to be present in abundant quantities in cocoa, and in minimally processed chocolates as well. Dark chocolate in particular has been found to contain more than three times the number of catechins as green tea, making it a even more healthier that we are least expecting it to be. The catechins contained in dark chocolate are said to be able to boost the immune system and help prevent heart disease and other chronic problems.

On top of these benefits, it is also known to be a good source of magnesium and copper, which are known to help regulate the blood pressure and heartbeat.

It is also important to keep in mind that the vast majority of the health benefits attributed are limited mainly to dark chocolate, which is quite different than milk chocolate and other varieties. Those people wishing to enjoy the many health benefits of chocolate would do well to limit their consumption of light and white chocolate, and to focus instead on the delicious and slightly bitter treat we know as dark chocolate.

Fortunately for lovers of dark chocolate, the major manufacturers and wholesalers are responding to these well publicized studies by offering more and more to their customers. In addition to existing Special Dark bars, for instance, Hershey has introduced a special line of dark Hershey Kisses, as well as varieties of many of its most popular candy bars. In the future dark chocolate lovers should not have to look too hard for the delicious taste and possible health benefits of their favorite sweet treat.

Readers, please take note : Stuffing yourself with chocolates is not a healthy habit. In particular, sweetened chocolates produce a lot of calories that can increase the fat retention in your body. The healthiest chocolates are those which contain plenty of flavonoids. Commercially sold chocolate bars, besides being sweetened, have varying contents of these substances.
