    Sunshine boosts sex drive 

    The idea of taking a break in the Caribbean sun to rejuvenate your sex life isn’t just an escapist fantasy, according to new research.

    An hour of sunbathing can boost a man’s testosterone levels – and his sex drive – by 69 per cent, European researchers reported in the Daily Telegraph have found.

    Sunshine is vital to boosting Vitamin D levels, and the new study shows Vitamin D is essential for good testosterone levels.

    Stimulated by UV radiation, 90 per cent of Vitamin D in the body is produced by the skin, although it can be found in cold water fish like tuna and salmon, and in cod liver oil.

    And while sunscreens with a sun protection factor of 8 or greater will block UV rays that produce Vitamin D, but it is still important to routinely use sunscreen whenever sun exposure is longer than 10 to 15 minutes.

    Testosterone Fluctuates With Sunshine

    Researchers at the Medical University of Graz in Austria found men with more Vitamin D per millilitre of blood had much more of the main male sexual hormone circulating than those with less.

    And the average amount of testosterone over the course of the year was subject to the same fluctuations as the Vitamin D level.

    Both decrease from October – at the beginning of the winter months – and reach their lowest level in March because of the weaker solar radiation during this period.

    Not Enough Sun

    Season, latitude, time of day, cloud cover, smog, and sunscreens affect UV ray exposure, so if you live somewhere with little sun, it is especially important to include good sources of Vitamin D in your food.

    In Boston – for example – the average amount of sunlight is insufficient to produce significant Vitamin D synthesis in the skin from November through February.

    Ad Brand, spokesman of the Sunlight Research Forum in Veldhoven in the Netherlands, said: “Men who ensure their body is at least sufficiently supplied with Vitamin D are doing good for their testosterone levels and their libido among other things.”

    Best Foods For Vit D

    While sunshine is the most effective Vitamin D source, it can also be obtained by eating fatty fish –cold water varieties like salmon, mackerel, tuna and sardines, by taking cod liver oil, eggs, beef liver, or UV irradiated mushrooms.

    Foods like cereals and milk are now routinely fortified with Vit D.

    Testosterone is the most important male sexual hormone. In males it is mainly responsible for the development of the sex organs, the formation and maintenance of the typical male sexual characteristics, sperm production and the controlling of male desire.

    Lance Armstrong’s Low Libido 

    Seven times Tour de France winner Lance Armstrong says he’s no sex champion – even though he’s recently announced the birth of his fourth child, son Max (“20 inches long, 7lbs 5oz, Mommy healthy and so am I”) on Twitter.

    In the three years he was “retired” from professional cycling Lance made a name for himself as a celebrity skirt chaser, leaving his wife and the mother of his three children for singer Sheryl Crow, then breaking up with her three months into their engagement to go on and date actress Kate Hudson and one of the Olsen twins, before setting up with Max’s mother Anna Hansen.

    But in an interview with the Men’s Journal he says he really doesn’t understand why chicks dig him. He says he is sure it isn’t his sex drive!

    “I had sex if I had the energy. I wasn’t one of those guys who believed in the myths about the guy losing his chi. The fact is that if you are riding your bike six, seven hours a day, you are not a sex champion. You’re just not. You have fatigue, low testosterone, and a lower libido. But you know, I never got any complaints.”

    Does Cycling Cause Impotence?

    Clearly the athlete who contested his eighth Tour de France this year and who is promising to be back in 2010 hasn’t yet been struck with the ‘cyclist’s curse’ of impotence predicted by prominent urologist Dr Irwin Goldstein in Bicycling Magazine a few years ago.

    Dr Goldstein got plenty of attention with his claim that “There are two kinds of cyclists: those who are impotent and those who will be.” The jury is still out on whether Lance has anything to worry about, because there have been no qualified or scientifically acceptable studies carried out on the link between impotence and bicycling.

    Sure, there is plenty of anecdotal and clinical evidence to confirm that long-term or endurance cycling causes numbness and discomfort in the genital region, but does that equate to long-term cycling impotence?

    A survey conducted on participants in a Norwegian endurance bike race found that 20% of the competitors reported penile numbness lasting from a few minutes to a day or more following the event and that 13% of competitors reported temporary impotence.

    Manufacturers are currently experimenting with new saddles to reduce pressure and give more support.

    Treatment for Cycling Impotence

    If you’ve noticed a decline in sexual performance – or like Lance you are feeling the effects of fatigue, low testosterone and lowered libido – there are a range of options you can consider from pharmaceuticals like Viagra, Cialis and Levitra to natural herbal supplements like Herbal Ignite (http://www.herbalignite.com) containing tribulus terrestris to boost testosterone. And in the meantime, until more hard evidence surfaces, you’ll be healthier getting on your bike and giving yourself a good cardio workout, than keeping off it because of fear of impotence.
