    Caffeine – Sex Booster or Cause of Infertility? 

    sex booster
    Four out of five Americans and two out of five Australians start the day with a coffee.

    It’s almost certainly not the same brew –“the best coffee in the world” – consumed by Jack Nicholson’s character in the 2007 movie The Bucket List.

    That was a rare blend known as Kopi Luwak, civet coffee – where the beans have passed through the digestive tracts of civet cats, and are gathered when the seeds, still coated in some cherry mucilage, are eliminated in the cat’s “poop”. Great!

    But whether you take your daily caffeine fix in Kopi Luwak or Starbucks, in cola, chocolate or black tea – there’s truckloads of conflicting evidence about whether caffeine is good for your health and love life, whether it boosts sexual desire or causes infertility.

    Good and Bad News About Caffeine

    Good: A new study shows caffeine gets females in the mood for sex. With a few provisos – if you’re a female rat who hasn’t previously experienced a caffeine “lift”  – it had them coming back for more – sex that is not coffee.

    Researcher Fay Guarraci, an assistant professor of psychology at Southwestern University in Georgetown, Texas, is cautious about whether it would boost women’s sex lives in the same way.

    “We gave only one dose of caffeine to animals who had never had caffeine before.

    “Most of the time, women drink coffee on a daily basis or ingest caffeine in cola beverages,” she observes. “In humans, it might enhance the sexual experience only among people who are not habitual users.”

    Bad:  More than four cups of coffee a day increases infertility in women who are already subfertile, according to a new European study. For many women though, it probably won’t make any difference.

    One study done in 2003 showed women who consumed less than 300 mg of caffeine a day (appx 2-3 cups of coffee) a day did not experience reduced fertility.

    Yet another study of over 1000 women found the risk of not conceiving to go up with each additional cup of coffee, where even one cup reduced a woman’s ability to conceive.

    The results are mixed for men as well. One study showed that sperm count, motility and abnormalities increased with the number of cups of coffee drank in a day – while another Brazilian study showed increased motility for mild to heavy coffee drinkers.

    Good: Coffee drinkers had a significantly reduced risk of diabetes, Parkinson’s Disease, cirrhosis of the liver, and gallstones.

    • A recent Harvard study of over 126,000 people conducted over 18 years found that compared to non-coffee drinkers, drinking 1-3 cups of coffee a day will reduce the risk of diabetes by single digits, but drinking 6 or more cups a day reduced that risk by 30% in women and 54% in men.
    • At least six studies have shown coffee drinkers are significantly less likely to develop Parkinson’s Disease (at least three studies showed that the more coffee you drank, the lower your risk).
    • Coffee drinking reduces the risk of cirrhosis of the liver by up to 80%, and cuts the risk of gall stones in half.

    Bad: Random Coffee Fact: People who buy coffee primarily at drive through windows on their way to work will spend as much as 45 hours a year waiting in line.

    Good: Caffeine aids weight loss

    Caffeine speeds your body’s metabolism so you burn calories at a faster rate, and it breaks down fat. Fat conversion is up to 30% more efficient when you consume caffeine before you exercise. It also keeps blood sugar levels higher, reducing appetite.

    “A Little Bad, A Lot of Good”

    Concludes Dr. Tomas DePaulis at Vanderbilt University Institute for Coffee Studies: “Overall, the research shows that coffee is far more helpful than harmful.” Drinking coffee, he says, brings little bad, but a lot of good.

    Caffeine and Your Sex Life 

    love coffeeWe drink around 4.4kgs each of it a year – that’s around 3 cups a day – and at those levels your mid morning coffee break is probably good for your health.

    It stimulates the nerve endings so gives a better mood, less fatigue, clearer thinking and better attention. Your metabolism speeds up, heart rate increases, bringing more oxygen to the muscles and generating more energy.

    But what about your sex life? There’s a confusing range of opinion about the impact caffeine has on sexual performance, from anecdotal forum comment from men saying they notice a distinct improvement when they drink less coffee, to recent research indicating  that for diabetic men in particular, a daily cup of coffee or two can improve sex by making diabetic medicines work more effectively.

    The secret it seems is in the level of consumption – below five cups a day it can be beneficial. Down five or more cups a day and you’ll be in danger of putting your sex life into reverse.

    Coffee for Diabetic Men’s Sex Lives

    Erectile dysfunction (ED) impacts between 35 to 75% of all male diabetic patients, three times the amount reported in non-diabetic males.

    While medications have been developed for ED, diabetic ED remains difficult to treat and no single treatment has proven effective for all diabetic men with ED.

    But a new joint Chinese-American study showing caffeine reversed ED in diabetic rats is giving new hope for a better love life for diabetic men.

    How Coffee Helped Improve Sex

    Erections are created by blood flow to the penis, and are dependent on what scientists refer to as the “NOcGMP pathway” (the Nitric Oxide pathway). In diabetic men, relaxation of penile arteries – allowing blood flow – is severely constricted.

    ED has most often been treated with medicines that act as inhibitors to prevent constriction, and because caffeine is a non-selective inhibitor, scientists in this study hypothesized that caffeine could help elevate cGMP and reduce constriction.

    Diabetic rats given caffeine for 8 weeks enjoy partially restored erectile function, and scientists predict a combination of caffeine and medication offers future treatment hopes.

    As a result of the study, the scientists gave a big tick to moderate coffee consumption – but warned that high levels (500mg – or more than five cups a day) could have negative effects such as impaired sleep and increased anxiety, both well-known factors in ED.

    Herbs for Sexual Performance

    Coffee is not the only natural stimulant which effects constriction and relaxation of blood supply to the penis. The so-called PDE-5 inhibitors – found in herbs like horny goat weed – operate in a similar way. Some herbal treatments for erectile dysfunction like Herbal Ignite contain horny goat weed as part of their formula. Etc etc – Sam can you improve this a bit?

    “Effect of Caffeine on Erectile Function Via Up-Regulating Cavernous cGMP in Diabetic Rats” appeared in the April 17, 2008 edition of the Journal of Andrology, published by the Department of Urology, Affiliated Drum Tower Hospital, Nanjing University, School of Medicine, Nanjing, Jiangsu, China ,and the University of Texas Medical School’s Department of Urology and MD. Anderson Cancer Center, both in Houston. Contributors included Run Wang, MD, FACS and Yutian Dai, MD, PhD with Rong Yang, Jiuling Wang, Yun Chen, and Zeyu, Sun.

    Breaking the No 4 Food Addiction – Caffeine 

    Do you reach for a caffeine fix every time you’re feeling tired? While some people drink just one cup of coffee a day, there are others who seem to be holding a coffee mug every time you turn around.

    Those who have serious cravings for caffeine throughout the day are most likely suffering from an addiction to caffeine. Caffeine stimulates activity in the brain, which in turn, causes the release of the hormone adrenaline. Despite achieving the desired effect, after the dose of caffeine wears off, it often creates a craving for additional caffeine to recreate the effect.

    Breaking Caffeine Cravings

    There are healthier, more effective ways of preventing fatigue throughout the day. First, make sure you are getting enough sleep! Second, exercise daily. Although many people mistakenly think that they will be more tired by exercising, they are actually wrong. Overall, exercise will increase your energy level and will enable you to overcome your food cravings.

    As well:

    • Eat five to six small meals a day and include some protein in each meal. This will help keep your blood sugar stable and provide you with the energy to keep going all day long.
    • Drink at least eight glasses of water. Water will help keep you energized
    • Drink a glass of water or green tea in the morning to help you wake up.
    • Get plenty of fresh air and sunshine each day. Use your usual coffee break to take a little brisk walk outside.
    • Switch to green tea. In addition to tasting great and giving you energy, it is packed with flavonoids and antioxidants, both of which are beneficial to your health.

    Start by cutting down on your caffeine consumption and replace as much of it as possible with green tea and water. Keep cutting more caffeine out every few weeks. Before you know it you will break the caffeine habit for good.
