The other component of that study is that the subjects ate much less saturated fat. Saturated fats are common in meat, butter, and coconut products, and they’re crucial for your body to function. Saturated fats keep the integrity of your cell membranes, and if you limit carbs and/or do Bulletproof Intermittent Fasting, saturated fats become a phenomenal source of energy for your brain.
The aim of treatment for hypogonadism is to normalize serum testosterone levels and abolish symptoms or pathological states that are due to low testosterone levels. The exact target testosterone level is a matter of debate, but current recommendations advocate levels in the mid-lower normal adult range (Nieschlag et al 2005). Truly physiological testosterone replacement would require replication of the diurnal rhythm of serum testosterone levels, but there is no current evidence that this is beneficial (Nieschlag et al 2005).
The biologically available part of total testosterone is called free testosterone, and it’s readily available to the cells. Almost every lab has a blood test to measure free testosterone. Even though it’s only a small fraction of the total, the free testosterone level is a pretty good indicator of low testosterone. It’s not perfect, but the correlation is greater than with total testosterone.

In my late 40’s I was on Androgel. I lost weight and gained muscle; became healthier over all, brighter outlook, more active, and a harder erection that had a mind of it’s own. Then I went on injectable testosterone. My numbers are normal but my weight is up even after eating less. As well everything else is shelter smelter. I intend to get back to Androgel. (this, of course, is my own personal study)
Our bodies need zinc to make testosterone. Zinc also blocks the action of aromatase, the enzyme that converts testosterone to estrogen. Oysters offer the highest amount of zinc per serving of any food. Just six oysters contain about 500 percent of the mineral’s recommended daily allowance (RDA). Other zinc-rich foods include lean meats and spinach.

A sedentary lifestyle is another scourge for modern civilization. And this is a serious danger for men. After all, if physical activity is minimal, the testosterone levels will decrease steadily. And in this situation, strength training exercises are a proven method for raising testosterone. Thus, sports exercises always helped raise the levels of male sex hormone. As a result, the testosterone levels elevate after every workout.

There have been case reports of development of prostate cancer in patients during treatment with testosterone, including one case series of twenty patients (Gaylis et al 2005). It is not known whether this reflects an increase in incidence, as prostate cancer is very common and because the monitoring for cancer in patients treated with testosterone is greater. Randomized controlled trials of testosterone treatment have found a low incidence of prostate cancer and they do not provide evidence of a link between testosterone treatment and the development of prostate cancer (Rhoden and Morgentaler 2004). More large scale clinical trials of longer durations of testosterone replacement are required to confirm that testosterone treatment does not cause prostate cancer. Overall, it is not known whether testosterone treatment of aging males with hypogonadism increases the risk of prostate cancer, but monitoring for the condition is clearly vital. This should take the form of PSA blood test and rectal examination every three months for the first year of treatment and yearly thereafter (Nieschlag et al 2005). Age adjusted PSA reference ranges should be used to identify men who require further assessment. The concept of PSA velocity is also important and refers to the rate of increase in PSA per year. Patients with abnormal rectal examination suggestive of prostate cancer, PSA above the age specific reference range or a PSA velocity greater than 0.75 ng/ml/yr should be referred to a urologist for consideration of prostate biopsy.
“I'm having great results. Everybody is seeing a difference. People say, “You look good! Did you lose weight? What are you taking?” I'm 59, and I'm bringing my belt down a couple different notches. I couldn't break 180 lbs for nothing, no matter what I tried. Now it's 175 lbs. and she's going from there. I was just doing it for the belly -- no matter what I just couldn't get rid of the belly (until now). And I'm not as tired as I used to be.“
"I went from 230 pounds down to 192. When my son got married, I went for the suit fitting, and I was a size 48. When I went back to do the final fitting, I was a 44! I want to keep getting it for the weight loss; I lost 4 inches around my belly, and I want to get rid of the rest of the weight around my belly. I’m 57, and my wife says I look like I’m back in my 30s. I have more energy for sure, and I’m going to participate in one of those Savage races where they have the obstacle courses with one of our kids."
The science is clear: Men’s body fat drains testosterone. We’re not talking pinchable back fat or squishable love handles. We’re talking classic belly fat. In medical parlance, it’s called visceral fat. Unlike fat that lies just beneath the surface of the skin, visceral fat nestles deep in the abdomen around the organs. It’s tenacious, dangerous, and hormonally active. The more visceral fat a man has, the higher his risk of type 2 diabetes, heart disease, high cholesterol, hypertension, insulin resistance, and colon cancer.

Let’s do a quick review of what I shared in the introduction to this series. August of last year was a tough month for me, primarily because of a huge and grueling project we were in the midst of here on the site. I was stressed out and my sleeping, healthy eating habits, and workout regimen all suffered. At the end of the month I got my testosterone levels tested and found that my total T was 383 ng/dL and my free T was 7.2 pg/mL – close to the average for an 85-100-year-old man.
I’m a low key,thinker-type, after a test I learned my T hormone was so low I should be rigid. TRT sent my drive into negative overdrive: ambition, cunning, entrepreneurial risk, physcal and psychological risks: drugs,you name it. I was lucky it happened after 50 years of memories ’cause I missd and have problems recalling the last seven years that I was on TRT (5 pumps a day of 1.25mgs). If you’re starting, take a pictoral record at the least of your monthly life ( a flick a month).
I definitely enjoyed an increase in muscle mass during my experiment. Despite dropping six percentage points in body fat in three months, my weight stayed about the same; I began the experiment weighing 185 pounds and I ended it weighing the same. The body fat I lost was replaced with muscle. It was fun to see and hear Kate’s reaction when I’d take off my shirt to get into the shower. “Whoa! Your muscles have gotten huge!”
The most commonly used testosterone preparation in the United States — and the one I start almost everyone off with — is a topical gel. There are two brands: AndroGel and Testim. The gel comes in miniature tubes or in a special dispenser, and you rub it on your shoulders or upper arms once a day. Based on my experience, it tends to be absorbed to good levels in about 80% to 85% of men, but that leaves a substantial number who don’t absorb enough for it to have a positive effect. [For specifics on various formulations, see table below.]

A testicular action was linked to circulating blood fractions – now understood to be a family of androgenic hormones – in the early work on castration and testicular transplantation in fowl by Arnold Adolph Berthold (1803–1861).[181] Research on the action of testosterone received a brief boost in 1889, when the Harvard professor Charles-Édouard Brown-Séquard (1817–1894), then in Paris, self-injected subcutaneously a "rejuvenating elixir" consisting of an extract of dog and guinea pig testicle. He reported in The Lancet that his vigor and feeling of well-being were markedly restored but the effects were transient,[182] and Brown-Séquard's hopes for the compound were dashed. Suffering the ridicule of his colleagues, he abandoned his work on the mechanisms and effects of androgens in human beings.


I turned 50 and noticed I had low energy and no desire to workout. I decided to try a testosterone enhancer. I bought these and upon taking them I felt immediate results. I then ordered 3 more bottles on the spot. It is truly amazing how much of a difference it has made in my strength and endurance. Not to mention stamina. I never would've guessed that anything would have such a noticeable positive effect on strength and energy. I am so impressed.
I have tried pellets, I went from 5 grams/day gel, to 10 grams, had little change due to work schedule and no energy made it difficult to manage daily. Levels got down to 78 at one point. Testo pellets worked great but it took 10 to make a difference and it brought me up to the 300-400 range. My body rejected 3 pellets and expelled them. Tried axiron, didn’t work, natesto, which the doc never heard off next, a Nasal spray which helped but the bottle ran out 5 days early either by my mistake or dosage problems. Back to 10 grams Testim AG ($360 after deductible) which helps if i could stay consistent but I’m 28. With a job, and health insurance, deductible issues I can not afford 800 dollars a month, 360 after deductible. Recent levels of FSH/LH are .7 and 1.2 (low). Total testosterone 114, free 18.9, and bioavalability at 39.6 (low). I had a MRI of my pituitary gland today, and get results next week. Hoping to start depo T next week as I return to work. If I can recommend anything to anyone, is make sure it’s affordable, you have the time or energy to apply/administer, and understand most people will not understand what you are going through. 2 killers of testosterone are chronic stress and lack of sleep. In 3 years of treatment I wish I came to this man’s article and others and read up prior because I’m on the brink of losing everything I’ve worked for due to hypogonadism. Wish you all results and good health, and thank you for a great article!
The sexual hormone can encourage fair behavior. For the study, subjects took part in a behavioral experiment where the distribution of a real amount of money was decided. The rules allowed both fair and unfair offers. The negotiating partner could subsequently accept or decline the offer. The fairer the offer, the less probable a refusal by the negotiating partner. If no agreement was reached, neither party earned anything. Test subjects with an artificially enhanced testosterone level generally made better, fairer offers than those who received placebos, thus reducing the risk of a rejection of their offer to a minimum. Two later studies have empirically confirmed these results.[75][76][77] However men with high testosterone were significantly 27% less generous in an ultimatum game.[78] The Annual NY Academy of Sciences has also found anabolic steroid use which increase testosterone to be higher in teenagers, and this was associated with increased violence.[79] Studies have also found administered testosterone to increase verbal aggression and anger in some participants.[80]
The final two studies looked directly at soy vs testosterone levels. The first looked at introducing consumption of soya flour on testosterone levels. They found that those who ate the Soy flour lowered their T levels during the study (43). And the second study looked at the consumption of soy protein isolates (powder) in healthy men. They found that testosterone levels decreased upon consumption of soy powder (45).
A: If a health insurance company is providing coverage for a medication, including testosterone replacement therapy, they determine the final cost of the product. Costs will vary from one health insurance plan to another. To determine the costs of the testosterone replacement options, the health insurance plan should be contacted. There are various options for testosterone replacement therapy including gels, injections, patches, and tablets that dissolve under the lip. All of the formulations can be effective and each has advantages and disadvantages. The most appropriate testosterone replacement therapy depends on a variety of factors, including cost, patient preference, and tolerability. Testosterone replacement gels, such as AndroGel and Testim, are very effective and easy to administer. AndroGel and Testim can be easily applied to the skin once daily. However, the gels can be irritating to the skin and AndroGel and Testim are typically quite expensive. Testosterone replacement injections, such as Depo-Testosterone (testosterone cypionate) and Delatestryl (testosterone enanthate), are usually inexpensive. The injections are given only once every one to two weeks. The major disadvantage with injectable testosterone is that testosterone levels may be difficult to control. Levels may be too high after an injection and too low before the following injection. A testosterone replacement patch, such as Androderm, is applied every night and left on for 24 hours. Androderm can be applied to the arm, back or stomach, in an area without too much hair. Androderm can cause irritation of the skin. A testosterone tablet, Striant, is placed under the upper lip against the gums and replaced every 12 hours. Striant molds to the upper gum so that eating and drinking can occur normally. The testosterone tablet can irritate the gums and cause a bitter taste and toothache. People with low testosterone should work with their doctor or healthcare provider to find a safe, effective, and affordable testosterone replacement option for them. For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action. Derek Dore, PharmD
The body’s endocrine system consists of glands that manufacture hormones. The hypothalamus, located in the brain, tells the pituitary gland how much testosterone the body needs. The pituitary gland then sends the message to the testicles. Most testosterone is produced in the testicles, but small amounts come from the adrenal glands, which are located just above the kidneys. In women, the adrenal glands and ovaries produce small amounts of testosterone.
Men's levels of testosterone, a hormone known to affect men's mating behaviour, changes depending on whether they are exposed to an ovulating or nonovulating woman's body odour. Men who are exposed to scents of ovulating women maintained a stable testosterone level that was higher than the testosterone level of men exposed to nonovulation cues. Testosterone levels and sexual arousal in men are heavily aware of hormone cycles in females.[46] This may be linked to the ovulatory shift hypothesis,[47] where males are adapted to respond to the ovulation cycles of females by sensing when they are most fertile and whereby females look for preferred male mates when they are the most fertile; both actions may be driven by hormones.
There are the testosterone deficiency signs, such as loss of sexual desire, erectile dysfunction, impaired fertility, chronic fatigue, etc. But it’s not always possible to understand which medical condition caused the decrease in testosterone levels. For example, if you always feel exhausted and have no sexual desire, it may provide evidence of depression.
“I'll be totally honest I tried a different product, and I wasn't happy with the different product and so I've been without any supplement for some time now, and I can really feel the difference. And I had fantastic results with the Andro400 Max. Probably lost 35 pounds. And more impressive than that was the inches I lost off of my belly and my waist. The increased energy is fantastic, and the mood enhancement is really good. I'm very impressed with it. You guys are considerably cheaper than the other brand. I get 2 bottles a month from you guys and that's even $15 less than the GNC product.”
In both men and women, imbalances in testosterone result in health issues like diabetes, obesity, metabolic syndrome, and osteoporosis. So testosterone is important for more than just men’s health issues; it crosses gender boundaries and affects all areas of the body. The Providers at New Leaf Wellness are aware of the risks and inconveniences that imbalanced hormone levels bring to the human body, and we are pleased to offer Natural Hormone Therapy to our clients.

The largest amounts of testosterone (>95%) are produced by the testes in men,[2] while the adrenal glands account for most of the remainder. Testosterone is also synthesized in far smaller total quantities in women by the adrenal glands, thecal cells of the ovaries, and, during pregnancy, by the placenta.[130] In the testes, testosterone is produced by the Leydig cells.[131] The male generative glands also contain Sertoli cells, which require testosterone for spermatogenesis. Like most hormones, testosterone is supplied to target tissues in the blood where much of it is transported bound to a specific plasma protein, sex hormone-binding globulin (SHBG).
Don’t waste your time with the gel, the Injectable is far superior. Also most will be given 200 mg cypionate per week, you can actually go much higher and feel a lot better and if combined with good resistance training and cardio achieve a very good figure and low fat percentage . There was actually a study overseas that said men could benefit with TRT at 600mg per week, although you will never see that happen with American doctors .
I am generally dubious about supplement claims & have tried a few other Testosterone boosters which had no effect I could tell. Being desperate to find something to help me feel better, I ordered Dr Martin's T Booster. It arrived on May 14th and after the first day I felt better & noticeably had more energy. I don't have that tired dead feeling every morning now when trying to get out of bed. I am able to do some work & physical activities without being exhausted to the point of being sick. I have been taking Dr Martin's T-Booster for 8 days now. While I am not out running marathons yet, I am feeling much better & hope to continue getting better as I keep taking it
A notable study out of Wayne State University in Indiana found that older men who had a mild zinc deficiency significantly increased their testosterone from 8.3 to 16.0 nmol/L—a 93 percent increase—following six months of zinc supplementation. Researchers of the study concluded that zinc may play an important role in modulating serum testosterone levels in normal healthy men.6
In decades past, this essentially meant that once your body hit a certain age, it no longer kept up with the young at heart. Luckily, today there is a variety of solutions to combat declining testosterone levels, including Test Boosters, dietary supplements which are formulated to help naturally stimulate the body’s production of testosterone. Sounds good, but not sure where to start? We’ve compiled the Top 10 Test Boosters for 2018 to help you make the best choice.
Zinc is little more of a nice-to-have ingredient than a must-have. It’s on our radar as an ingredient that possibly boosts testosterone levels, and while we couldn’t find enough supporting evidence that taking zinc would increase natural testosterone, low zinc levels have been connected to infertility. A low zinc level is also possibly a sign of hypogonadism. The closest support we found is in a study which found that people recovered from nutritional deficiency-related problems more quickly if they took a zinc supplement than those who did not. Zinc is available in many foods, such as oysters, fortified breakfast cereals, and red meat.
If men’s brain, muscles, and bones are being affected daily due to low testosterone, and it is what makes men, men, why aren’t we doing more about this serious health problem? Could there be a political correctness crept in the scientific community that is hindering newly invigorated research in this area? I thought that scientific inquiry suppose to go where the evidence leads. It appears that some honest experts are opening their eyes to this truth.

The sad truth, is that these purported testosterone support products were completely and utterly useless. They did absolutely nothing for testosterone production due to the simple fact that they didn’t contain any ingredients shown in human research trials to actually support testosterone production. Sure, they included all sorts of ancient herbs and botanical extracts that worked well in rats, but nary a compound that would actually benefit a real live human being.


When I was using the gel my testicles also shrank a bit, but not anywhere near this amount. And when I stopped using the gel they plumbed back up again to their former size. It took some time but their size came back. This may be an issue for the younger guys, but I think most older guys can easily handle this as no big deal, because overall it’s not.
Sleep apnea is another frequently listed contraindication to testosterone treatment. There have been a few reports of the development, or worsening, of sleep apnea during testosterone therapy (Matsumoto et al 1985) but sleep apnea is actually associated with lower serum testosterone levels (Luboshitzky et al 2002). The reduction in fat mass during treatment with testosterone could potentially be beneficial for sleep apnea, so many specialists will still consider patients for treatment with appropriate monitoring. It is wise to take a clinical history for sleep apnea during testosterone treatment in all men and perform sleep studies in those who develop symptoms.
Want faster recovery and more lean muscle gains?  Advanced BCAA is your answer.  Why?  Because everyone knows that BCAA’s (branched chain amino acids)  are the building blocks of muscle.  You’re not going to grow an ounce of muscle without BCAA’s.  Now BCAA’s can be found in foods like milk and meat, and of course whey protein contains BCAA’s.  However Advanced BCAA’s is a special ultra fast, absorbable form of BCAA that will sky rocket your muscle gains.  It provides the body with BCAA’s in peptide form.  Which means it is digested very fast,  faster than normal BCAA’s that you’ll find on the retail shelf.  Get a BCAA supplement that gives you the best chance for success.  GET ADVANCED BCAA!
Hypogonadism is highly prevalent amongst men with diabetes mellitus type 2 or symptoms of the metabolic syndrome, including insulin resistance, impaired glucose regulation, obesity, and hypertension.1,6,13,14,17,18 Low testosterone in many men with diabetes remains undiagnosed and untreated, and current guidelines recommend measurement of testosterone levels in such patients and, equally, that such chronic diseases should be investigated and treated in men with hypogonadism.1,6 It is not yet fully known whether diabetes is a cause or a consequence of low testosterone, and the full effects of testosterone administration on glycemic control in hypogonadal men with diabetes are unclear. However, there are indications that treating hypogonadism may have benefits on metabolic status in men with diabetes, and there is evidence that testosterone replacement therapy has a beneficial effect on risk factors for diabetes such as central obesity, insulin sensitivity, glucose control and blood lipid profiles in hypogonadal men with type 2 diabetes.14,19,20

In addition to these effects, DHEA supplementation also increases FREE testosterone levels. As you may or may not know, testosterone is found in the body in both free and bound forms. Free testosterone is the biologically active kind that we want more of in order to improve energy, strength, recovery, and sexual function. Bound testosterone is biologically inactive, due to serum hormone-binding globulin (SHBG).
When you're under a lot of stress, your body releases high levels of the stress hormone cortisol. This hormone actually blocks the effects of testosterone,6 presumably because, from a biological standpoint, testosterone-associated behaviors (mating, competing, aggression) may have lowered your chances of survival in an emergency (hence, the "fight or flight" response is dominant, courtesy of cortisol).
Hi my names Graham. I’ve suffered with Gyno for most of my adult life. Even when I’ve lost a ton of weight , those two unhelpful bags of fat are still there. To save me 4 to 6 grand on liposuction or surgery, will an estrogen blocker and testosterone booster help. I’ve also heard of a cream called andractim that can help , but they are expensive. Any advice would be great . Thanks.

I noticed that you say that those that have prostate cancer should not have testosterone replacement therapy, Why-in light of the studies that say that there is no danger from testosterone therapy to one that had/has prostate cancer? If this is your opinion do you have any suggestions as to what I should do about my symptoms? Does testosterone replacement therapy actually do anything?
Also, due to the intake of these synthetic substances, men start behaving in a very excited way, as well as demonstrate high levels of aggression and even violence. So, the men’s behavior may be antisocial. In addition, the men will experience breast enlargement and testicular shrinkage. The other adverse effects include hypertension, tumor growth, heart attacks and strokes, as well as development of liver disorders. It’s obvious that the numerous dangers of steroid use far outweigh a few benefits which they bring.
Dr. Abraham Morgentaler, an associate professor of surgery at Harvard Medical School and the director of Men’s Health Boston, specializes in treating prostate diseases and male sexual and reproductive difficulties. He has developed particular expertise in treating low testosterone levels. In this interview, Dr. Morgentaler shares his views on current controversies, the treatment strategies he uses with his own patients, and why he thinks experts should reconsider the possible link between testosterone-replacement therapy and prostate cancer.
"I'm 53 years old and my passion is surfing the oceans worldwide – big waves. Since taking Andro400, I'm now down to my ideal weight – from 185 to 175 now which is probably a net 15 pound loss, taking into account that the increased muscle I have now is heavier than the fat it replaced. My energy level is up. I feel strong and more physically fit in general. Also, from surfing I have been injured many times – for example I've broken my neck and pelvis among other things. Taking Andro400, I have much less pain overall – and I've been able to take less pain medication and anti-inflammatory drugs.”
Testosterone plays a role in certain behaviors, including aggression and dominance. It also helps to spark competitiveness and boost self-esteem. Just as sexual activity can affect testosterone levels, taking part in competitive activities can cause a man’s testosterone levels to rise or fall. Low testosterone may result in a loss of confidence and lack of motivation. It can also lower a man’s ability to concentrate or cause feelings of sadness. Low testosterone can cause sleep disturbances and lack of energy.
Testosterone may strengthen your heart. Research on testosterone’s relation to heart health is split. Some scientists have found that men with higher testosterone levels have an increased risk of heart disease, while recent studies have shown that men with below-normal T levels are more at risk for heart problems. The research is still on-going, but many doctors find the evidence compelling that optimal testosterone levels can help prevent cardiovascular disease.
The other component of that study is that the subjects ate much less saturated fat. Saturated fats are common in meat, butter, and coconut products, and they’re crucial for your body to function. Saturated fats keep the integrity of your cell membranes, and if you limit carbs and/or do Bulletproof Intermittent Fasting, saturated fats become a phenomenal source of energy for your brain.
The use of these supplements can help to burn fat and build muscles. As a result, the health and strength of your muscles and bones improve that ultimately leads to a strong and healthy body. Another prominent feature of Testosterone Booster is that it can help to elevate mood and energy. These supplements contains a powerful blend of natural herbs. These natural herbs have healthful properties. Thus, you can have the energy and stamina to perform your best in the gym. Furthermore, these supplements will also help you to increase your productivity at work because of your improved energy levels.
In contrast to steroids, testosterone boosters have a fully different mechanism of action. They are the products which contain the natural ingredients only. These ingredients act by stimulating the man’s body to synthesize own testosterone. So, testosterone levels grow naturally without negative health effects associated with the intake of steroids.
Hello I’m 22 years old and for years I’ve been struggling with hypothyroidism and depression. Recently I went to check my blood for low T and was shocked but not surprised at the level (125). That’s terrible for a 22 year old given that’s the time my testosterone is supposed to be the highest. Anyways I’ve been prescribed depo testosterone 200ml bottle. I give myself a shot each week and haven’t really noticed much change. I know I have to give it time, but is there anything else I can do or should be prescribed to help speed up the process?
The most popular way is to combine with a good tasting protein powder. Advanced BCAA’s taste very bitter due to the high amount of peptides. Peptides taste very bitter. You want to use 1 tsp of Advanced BCAA’s with every serving of protein powder. This will really upgrade the quality of the protein powder by adding BCAA, AND in peptides form. If you are using a whey protein you’ll increase the overall BCAA content by over 20%
Let’s first start off by saying, there is no comparison of natural testosterone boosters to synthetic.  When referring to synthetic, we’re talking anabolic steroids.  At that point, you’re comparing apples and oranges.  Which is best—natural or synthetic?  Synthetic.  It is much easier to put on quality muscle mass while using anabolics than it is using a natural testosterone booster.  One is basically giving you synthetic testosterone while the other is giving you a minor boost in natural testosterone production.  However, not only are there side effects to the use of anabolics, but they are also illegal in the United States unless used under a doctor’s supervision with a prescription.
The basis for my thinking that T levels could be boosted by cold baths came from a post I wrote a few years ago on the benefits of cold showers. One benefit I found in my research was that they could increase testosterone levels. I mentioned a 1993 study done by the Thrombosis Research Institute in England that found increased T levels after taking a cold shower. Here’s the thing. I can’t find a link to the original source and I can’t find any other studies that support this claim! So without supporting research, I’m unsure of the effects of cold showers on testosterone.
When testosterone and endorphins in ejaculated semen meet the cervical wall after sexual intercourse, females receive a spike in testosterone, endorphin, and oxytocin levels, and males after orgasm during copulation experience an increase in endorphins and a marked increase in oxytocin levels. This adds to the hospitable physiological environment in the female internal reproductive tract for conceiving, and later for nurturing the conceptus in the pre-embryonic stages, and stimulates feelings of love, desire, and paternal care in the male (this is the only time male oxytocin levels rival a female's).[citation needed]
Our bodies make testosterone while we sleep. In one study, men who got five hours of sleep a night had testosterone levels 10 to 15 percent lower than when they got a solid eight hours. The study, conducted by the University of Chicago, found that skimping on sleep reduced the men’s T levels by an amount equivalent to aging 10 or more years. While it can be challenging to change your sleep habits, says Natasha Turner, ND, you can “start going to bed 15 minutes earlier each week until you reach your target time.”
Epidemiological studies suggest that many significant clinical findings and important disease states are linked to low testosterone levels. These include osteoporosis (Campion and Maricic 2003), Alzheimer’s disease (Moffat et al 2004), frailty, obesity (Svartberg, von Muhlen, Sundsfjord et al 2004), diabetes (Barrett-Connor 1992), hypercholesterolemia (Haffner et al 1993; Van Pottelbergh et al 2003), hypertension (Phillips et al 1993), cardiac failure (Tappler and Katz 1979; Kontoleon et al 2003) and ischemic heart disease (Barrett-Connor and Khaw 1988). The extent to which testosterone deficiency is involved in the pathogenesis of these conditions, or to which testosterone supplementation could be useful in their treatment is an area of great interest with many unanswered questions.
