Are you one of the many people in Hollywood who are burning the candle at both ends and maybe only getting 4 or 5 hours of sleep a night? Are you also one of those guys having problems with his sex drive and feeling out of sorts? Well, recent studies done in Hollywood in the last 3 years show that these symptoms could all be due to the effect of sleep on testosterone – just how, though, may be a chicken and egg question!
While it’s true that lower testosterone levels can be the cause of a sluggish sex drive and irritability it seems to be a matter of research opinion whether low sleep levels cause low testosterone or low testosterone causes lack of sleep.
Hormone Imbalance in Women
Marijuana attacks your precious testosterone in almost every negative way possible. One study after another has shown that cannabis lowers testosterone. For example one research team found that "a reanalysis of existing data established that testosterone levels are depressed both after smoking one marijuana cigarette and after intravenous infusion of delta-9-tetrahydrocannabinol, a pharmacologically active component of marijuana". The same study concluded that it would take at least 24 hours for testosterone levels to normalize after marijuana use. (NOTE: It's not just the smoke - an IV will do it.)
Another study found that not only was testosterone decreased after short term marijuana use, but leutenizing and follicle stimulating hormone were lowered as well. And just to add to the endocrinological misery, the arch-villain and stress hormone cortisol was raised as well. There are also studies in animals and humans that strongly indicate that marijuana blunts growth hormone response as well. And so it is no wonder that animal studies show that marijuana use shrinks the testes. So, if you're not happy with lowered testosterone, infertility and elevated cortisol, you can sit around enjoying the fact that you've got a little more air flow through your boxers.
You should also know that there are many reports that chronic marijuana use leads to gynecomastia, i.e. "enlarged male breasts", due to its abundant amounts of phytoestrogens. One journal writer pointed out that "given the effects of marijuana on the HPG axis in males and the possibility that noncannabinoid components of marijuana smoke have affinity to the estrogen receptor, an association with gynecomastia is plausible but has not been convincingly demonstrated". Remember that estrogen fights against testeosterone in the body as well.
Marijuana has also recently been flagged as particularly dangerous for young people because it decreases seratonin and increases norepineprine. While these are not sex hormones like testosterone, these can alter mood negatively and, through prolonged use, may permanently alter anxiety levels and reaction to stress. Again, the researchers are suggesting this may have long term, possibly lifetime anxiety and mood repercussions. I would also add that any increase in stress will also likely lower testosterone as well.
So we ask the question, "Could someone please explain again why anyone in their right mind would smoke marijuana?" The only thing we can think of is the extra hydrogen cyanide. That's right - marijuana tobaco is much higher in hydrogen cyanide - probably five times higher - than cigarette tobacco. Maybe that partially explains why habitual pot smoking is so hard on the lungs and why cannabis use has also now been linked to the most aggressive form of testicular cancer.
Not to make the bad news even worse, but there is also considerable reported evidence of erectile dysfunction among chronic marijuana users. This is undoubtedly partially due to the lowered testosterone. However, the other reason was discovered by one study that showed marijauna effected Nitric Oxide and summarized by saying, "We conclude that early endothelial damage may be induced by chronic cannabis use (and endocannabinoid system activation". Let me translate that: it may take your sex life with it. If so, decreased sexual activity is also associated with lowered testosterone levels as well.
The tragedy with marijuana is that many cultures and youth are embracing marijuana as more "natural", but this is far from being the case. One recent study found that marijuana induces just as much cell toxicity and DNA damage as cigarette smoke. The researchers were very clear that marijuana displayed just as much cancer causing power as the cigarette smoke: "In addition, when corrected for total particulate matter yield, little difference was observed in the mutagenic activity of samples smoked under the extreme vs the standard regime for both tobacco and marijuana condensates".
In summary, there is significant evidence that marijuana lowers testosterone, nitric oxide, leutinizing hormone, growth hormone and raises cortisol at the same time. Hormonally, there is no justifiable reason for cannabis use.

Are you one of those guys who are burning the candle at both ends and maybe only getting 4 or 5 hours of sleep a night? Are you also one of those guys having problems with his sex drive and feeling out of sorts? Well, recent studies done in the last 3 years show that these symptoms could all be due to the effect of sleep on testosterone - just how, though, may be a chicken and egg question!
While it's true that lower testosterone levels can be the cause of a sluggish sex drive and irritability it seems to be a matter of research opinion whether low sleep levels cause low testosterone or low testosterone causes lack of sleep.
Here's what we know about sleep, and testosterone to date as it relates to men:
After age 30, men's testosterone levels drop between 1 and 2% a year! By the time they reach 40 they start experiencing trouble sleeping. They complain of less deep sleep time, the period of sleep where the body repairs itself.
In fact, as a man gets older, the most recent studies assert, he can lose deep sleep time altogether! That means the older a man gets, the more his testosterone levels continue to decline, the less deep sleep he gets, the more his body's repair mechanisms decline and the higher his risk climbs for disease!
The reason for this decline in deep sleep time is thought to be due to a loss of neuron activity, which synchronizes brain activity. These neurons are responsible for about 20% of achieving deep sleep. They are intact in young men and get further scrambled as a man ages.
To further complicate things, low testosterone levels are thought to contribute to this loss of neuron activity in the brain. The take away of these studies, then, whichever perspective you come from, seem to say that restoring testosterone to healthy, youthful levels would likely help a man not only achieve deep, restorative sleep again, but also keep him healthier, re-invigorate his sluggish sex drive and keep him in a happier frame of mind.
Do You Have Symptoms of Low Testosterone?
One of the most frequent complaints I hear from my over-40 patients is that their sex drive has diminished significantly from when they were younger. One of the first things I do is to check a testosterone level and most often find that it is decreased. Interestingly, as well, is that they also often complain of not sleeping very much and are depressed!
Now whether their lack of sleep is from a too hectic lifestyle, stress, or from their decreased testosterone level, is not clear. However, when I recommend that they try to get between 6-8 hours of sleep a night their testosterone levels seem to naturally increase and their mood is brighter!
But decreased testosterone levels don't just affect men over 50, it can start as young as the 30-40's! Many men don't seek treatment because they think it's just a part of getting older and they're embarrassed to talk about it! Like menopause in women, low testosterone is not something men have to suffer through just because it's associated with getting older. Here are some other symptoms you may not associate with low testosterone levels:
•Emotional changes, like depression, irritability, "grumpy old man" syndrome
•Decreased muscle strength
•Loss of height
•Weight gain, especially belly fat
What Does Cause Low Testosterone?
Low testosterone levels can be caused or aggravated by a number of things both nutritional and environmental. For my patients who have lower than optimal testosterone levels, here are some other things I tell them to pay attention to in their diet and lifestyle:
•Xenoestrogens - in food and water supplies. These are "environmental estrogens" from soy products and plastics that get into our food and can decrease testosterone levels. Stay away from foods containing soy, most notably protein bars and soymilk. If you buy frozen foods, transfer them from their plastic container into a glass dish before heating.
•Lack of Protein - men need between 0.5 to 1 gram of high quality protein per pound of body weight per day to both build muscle strength and testosterone. Sources include pork, beef, and chicken, which also have higher levels of zinc, which is testosterone friendly.
•Lack of Cholesterol - many men over 40 are watching cholesterol intake for the sake of their arteries, but too little cholesterol will stop testosterone production. Aim for about 30% fat, mostly monounsaturated (nuts, olive oil) and some saturated (red meat, eggs) to build testosterone. Go very light, or leave out, polyunsaturated fats (fish, vegetable oils) as studies have shown they can decrease testosterone perhaps because they may contain xenoestrogens.
•Lack of Nutrition - zinc is a major building mineral for testosterone. The B vitamins, especially B1, B6, and B12 are helpful in keeping testosterone levels healthy. Be sure that your vitamin/mineral supplement includes these.
•Too Much Alcohol - alcohol increases blood sugar levels, which decreases testosterone. Limit to a few drinks per week.
•Lack of Sleep - as mentioned earlier, less than 6 hours of sleep a night can seriously rob your body of its repairing mechanisms and this includes the re-manufacturing of hormones like testosterone. See that you get at least 6-8 hours of sleep at night, more if you have been ill or under a lot of stress. Try some natural sleep aids like Valerian, calcium/magnesium supplements with some warm milk before bed. Cut back caffeine to not past 4 pm, and limit heavy meals to 2-3 hours before bedtime.
Researchers may finally decide which comes first; low testosterone then poor sleep, or poor sleep then low testosterone. In the meantime, I'm going to continue to counsel my patients that adequate sleep is at least a significant factor in low testosterone levels. However, before you start thinking dangerous steroids or prescription testosterone replacements, try the natural suggestions offered here. I believe your T-levels will be up to optimal levels and your sex drive and pleasant mood back on track in no time!

How Bio-Identical Hormone Replacement Therapy Is Used To Treat Menopause
Have you ever thought, "I just can not seem to get motivated anymore to workout. I just don't understand why I have not lost a pound in two months. My bench press is going down and not up, how can this be?"
We have all experienced time periods where all the hard work, dedication and even desperation does not seem to be enough to jump start us. We focus so much on what we are not doing we begin to lose sight of main reason for exercising in the first place. Before you know it you start entertaining the idea of quitting.
ALl of us have heard of the eighty - twenty rule in life. This is where our lives are built on twenty percent of our efforts. The remaining eighty percent seems too be pushed along by the other twenty percent. When it comes to our weight loss and fitness goals lets look at the same percentages in another light. How about the eight twenty rule in our attitudes?
When I first started exercising and bodybuilding over twenty years ago I knew absolutely nothing about fitness, food or where my future was headed. However, what I did believe was that if I kept consistent, something had to change. With that attitude came a hope for the future and an understanding that good days would be followed by some bad ones.
It is unrealistic for you and me to think that every day in the gym and at the table will be great? We will be tempted to eat badly and we will be discouraged to go workout from time to time. This is reality. However, understanding that in the long run if you have more good days than bad, things will be work out good for you. This mindset is the key longevity. Here are some ideas on how to follow the 80/20 rule:
1. Write out in detail your yearly goal.
2. Get an accountability partner.
3. Focus on internal health vs. external.
4. Focus on the feeling not the work.
Best of luck and remember it's about the BIG picture!

Hollywood is a city in Broward County, Florida, between Fort Lauderdale and Miami. The average temperature is between 68 and 83°F. As of July 1, 2015 Hollywood has a population of 149,728. Founded in 1925, the city grew rapidly in the 1950s and 1960s, and is now the twelfth-largest city in Florida. Hollywood is a principal city of the Miami metropolitan area, which was home to an estimated 6,012,331 people at the 2015 census.
Joseph W. Young founded the city in 1925. He dreamed of building a motion-picture colony on the East Coast of the United States and named the town after Hollywood, Los Angeles, California. Young bought up thousands of acres of land around 1920, and named his new town "Hollywood by the Sea" to distinguish it from his other real estate venture, "Hollywood in the Hills", in New York.
Young had a vision of having lakes, golf courses, a luxury beach hotel (Hollywood Beach Hotel, now Hollywood Beach Resort), country clubs, and a main street, Hollywood Boulevard. After the 1926 Miami hurricane, Hollywood was severely damaged; local newspapers reported that Hollywood was second only to Miami in losses from the storm. Following Young's death in 1934, the city encountered more terrific hurricanes and the stock market crashed with personal financial misfortunes.
