Autopsy studies have found histological prostate cancer to be very common, with one series showing a prevalence of greater than fifty percent in men over age sixty (Holund 1980). The majority of histological cancers go undetected so that the clinical incidence of the disease is much lower, but it is still the most prevalent non-skin cancer in men (Jemal et al 2003). Prostate cancer is also unusual in comparison to other adult cancers in that the majority of those with the disease will die of other causes. Treatment of prostate cancer with androgen deprivation is known to be successful and is widely practiced, indicating an important role for testosterone in modifying the behavior of prostate cancer. In view of this, testosterone treatment is absolutely contraindicated in any case of known or suspected prostate cancer. The question of whether testosterone treatment could cause new cases of prostate cancer, or more likely cause progression of undiagnosed histological prostate cancer that would otherwise have remained occult, is an important consideration when treating ageing males with testosterone.
While I do have a pretty manly mustache, I’m not a doctor or a medical expert. I’m a guy with a law degree he’s never used who blogs about manliness. What I’m about to share shouldn’t be taken as a substitute for qualified medical expertise. It’s simply my experience and views on the subject. Before you make any changes in lifestyle or diet, talk to your doctor or healthcare provider. Be smart.

The hormone testosterone plays a major role in a man’s life. “We’re literally better at who we are if our T levels are thriving,” says Chad Howse, co-author of The Man Diet: A Proven Guide to More Energy, Increased Virility, and Higher Testosterone Levels. T affects just about everything, from a man’s appearance to his physical and emotional health.
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]
This evidence, together with the beneficial effects of testosterone replacement on central obesity and diabetes, raises the question whether testosterone treatment could be beneficial in preventing or treating atherosclerosis. No trial of sufficient size or duration has investigated the effect of testosterone replacement in primary or secondary prevention cardiovascular disease. The absence of such data leads us to examine the relationship of testosterone to other cardiovascular risk factors, such as adverse lipid parameters, blood pressure, endothelial dysfunction, coagulation factors, inflammatory markers and cytokines. This analysis can supply evidence of the likely effects of testosterone on overall cardiovascular risk. This has limitations, however, including the potential for diverging effects of testosterone on the various factors involved and the resultant impossibility of accurately predicting the relative impact of such changes.

From there, you’ll want to adjust how you train, since certain activities provide an especially powerful stimulus for testosterone. Research published in the journal Sports Medicine found that in order to experience a strong testosterone response from exercise, your workouts should be high in volume and produce a metabolic response. Churn through many exercises, sets, and reps, and focus on intense bursts of exercise with short rest periods.


Keep more weapons in your arsenal: Occasionally use lifting methods like forced reps, negatives, and dropsets to further stress your body. Personal trainer and fitness journalist Michael Berg explains in "6 Ways to Crank Up Your Testosterone Levels" that going beyond muscular failure with these techniques has been shown to pump up T-levels in study subjects.[16]
Grape seed extract is another ingredient with not enough research to suggest a dosage. Grape seed extract can interact with drugs like “blood thinners, NSAID painkillers (like aspirin, Advil, and Aleve), certain heart medicines, cancer treatments, and others.” If this sounds like you (or if you ever pop an Advil to clear off a headache), you’ll need to speak with a doctor to make sure this supplement is safe to take.
“I did a lot of research on Andro400 before I ordered it because I've tried other products in the past and they haven't worked. But with this I could not believe the difference within, literally within a month. I'm 62 years old and since I started taking it I have lost 37 lbs. And I have more energy than I've had in 20 years. It's still coming off, but it's coming off slower now. It was the belly fat. I could get weight off but I could never get the tummy off, and now the tummy's coming off. Libido -- everything's better all the way around.“
A related issue is the potential use of testosterone as a coronary vasodilator and anti-anginal agent. Testosterone has been shown to act as a vasodilator of coronary arteries at physiological concentrations during angiography (Webb, McNeill et al 1999). Furthermore men given a testosterone injection prior to exercise testing showed improved performance, as assessed by ST changes compared to placebo (Rosano et al 1999; Webb, Adamson et al 1999). Administration of one to three months of testosterone treatment has also been shown to improve symptoms of angina and exercise test performance (Wu and Weng 1993; English et al 2000; Malkin, Pugh, Morris et al 2004). Longer term studies are underway. It is thought that testosterone improves angina due its vasodilatory action, which occurs independently of the androgen receptor, via blockade of L-type calcium channels at the cell membrane of the vascular smooth muscle in an action similar to the dihydropyridine calcium-channel blockers such as nifedipine (Hall et al 2006).
You may find this hard to believe, but some common breakfast foods like Kellogg’s corn flakes and Graham crackers were invented 100 years ago to lower male libido. Kellogg and Graham believed that male sexual desire was the root of society’s problems, so they set out to make bland foods that would take away libido (this is absolutely true; look it up). That low fat, grain-based thing absolutely works wonders for lowering testosterone.
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.
The mineral zinc is important for testosterone production, and supplementing your diet for as little as six weeks has been shown to cause a marked improvement in testosterone among men with low levels.1 Likewise, research has shown that restricting dietary sources of zinc leads to a significant decrease in testosterone, while zinc supplementation increases it2 -- and even protects men from exercised-induced reductions in testosterone levels.3

This is the best BCAA supplement ever created.  You see this is not your typical BCAA supplement that all the other supplement companies sell.  Those products are simply free-form amino acids made by some Chinese manufacturer and packaged in the United States.  Free form amino acid supplements have been around since the 1980’s and they have never been proven to be helpful in building muscle mass.  In fact after whey protein came out in the 90’s it really made BCAA amino acids obsolete because whey protein contains over 30% BCAA.  If you want more BCAA’s simply use another scoop of whey protein instead of BCAA powder.  Its cheaper, tastes better, and contains plenty of BCAA plus all the other amino acids.  Ok so now that I have convinced you that free form BCAA’s supplements are pretty much worthless let me tell you about our new Advanced BCAA’s.
More recently, a study from 2015 noted that consuming 600mg daily of standardized fenugreek extract for eight weeks increased free testosterone levels compared to placebo. The test group also experience an increase the the number of repetitions the could perform in the leg press before reaching failure. And, to top it off, subjects receiving the fenugreek supplement dropped body fat without losing strength.
Hi Dean, thanks for reaching out bro! While testosterone boosters will help increase your T levels, strength, and libido, you need to make sure you’re eating the right foods and exercising in the right way. What is your current diet and workout plan? Maybe we can help? If you’re serious about getting in shape, a quality testosterone booster can certainly help. If you have a look at our top testosterone booster page, you’ll see TestoFuel is our best choice. If you have any more questions, don’t hesitate to write back! All the best bro, don’t give up, you can do it!
Fenugreek is an enigma, deep-fried in a mystery, and wrapped in secrecy. It can actually LOWER your testosterone levels while simultaneously increasing your libido and athletic performance, 2 effects that correlate with elevated testosterone levels.  Strange.  This is the first supplement I have come across that might have the opposite of the desired effect, and yet be worth taking anyway.
BCAA peptides are the building blocks of muscle.  Your body cannot make BCAA’s.  You have to eat them.  One easy way of course is food and things like whey protein powder.  That is why whey protein works so well because it contains BCAA’s at high levels.  Advanced BCAA is 50% BCAA in peptide form!!  Peptides are digested faster and more efficiently than whole foods and normal protein powders.  This means more muscle building and recovery support!!
Most studies support a link between adult criminality and testosterone, although the relationship is modest if examined separately for each sex. Nearly all studies of juvenile delinquency and testosterone are not significant. Most studies have also found testosterone to be associated with behaviors or personality traits linked with criminality such as antisocial behavior and alcoholism. Many studies have also been done on the relationship between more general aggressive behavior/feelings and testosterone. About half the studies have found a relationship and about half no relationship.[66] However, later it was found out that testosterone activates dominant, aggressive behavior if at the same time a person has high testosterone and low levels of cortisol in the blood. Conversely, a high level of testosterone and high levels of cortisol do not stimulate dominant behavior. Because cortisol inhibits the action of testosterone.[67][68][69][70] This is probably why the results of the experiments were inconsistent.

The mechanism of age related decreases in serum testosterone levels has also been the subject of investigation. Metabolic clearance declines with age but this effect is less pronounced than a reduction in testosterone production, so the overall effect is to reduce serum testosterone levels. Gonadotrophin levels rise during aging (Feldman et al 2002) and testicular secretory responses to recombinant human chorionic gonadotrophin (hCG) are reduced (Mulligan et al 1999, 2001). This implies that the reduced production may be caused by primary testicular failure but in fact these changes are not adequate to fully explain the fall in testosterone levels. There are changes in the lutenising hormone (LH) production which consist of decreased LH pulse frequency and amplitude, (Veldhuis et al 1992; Pincus et al 1997) although pituitary production of LH in response to pharmacological stimulation with exogenous GnRH analogues is preserved (Mulligan et al 1999). It therefore seems likely that there are changes in endogenous production of GnRH which underlie the changes in LH secretion and have a role in the age related decline in testosterone. Thus the decreases in testosterone levels with aging seem to reflect changes at all levels of the hypothalamic-pituitary-testicular axis. With advancing age there is also a reduction in androgen receptor concentration in some target tissues and this may contribute to the clinical syndrome of LOH (Ono et al 1988; Gallon et al 1989).
‘Testosterone boosting’ products  - found online, or in health food or body-building shops, these products claim to boost testosterone levels if you buy them. The majority of these products will not have the effect you want and are not worth spending money on. Any of these products that do have a real effect may have a form of prescription medication in which is both dangerous and illegal.
Men can experience a range of symptoms if testosterone decreases more than it should. Low testosterone, or low T, is diagnosed when levels fall below 300 nanograms per deciliter (ng/dL). A normal range is typically 300–1000 ng/dL, according to the U.S. Food and Drug Administration. A blood test called a serum testosterone test is used to determine your level of circulating testosterone.
In males, testosterone is synthesized primarily in Leydig cells. The number of Leydig cells in turn is regulated by luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In addition, the amount of testosterone produced by existing Leydig cells is under the control of LH, which regulates the expression of 17β-hydroxysteroid dehydrogenase.[132]
So if you’re intent on maximizing your testosterone levels, and/or you have applied all of the above and you’re still not satisfied with your results (which would be surprising) then you could try the below. I will point out that some of these tips may not have the scientific evidence to back them up like the previous points, but I can assure you that either I have or do use them (and have positive results), or a client has used them with pleasing results, or finally it is such a new conception that there isn’t enough evidence to prove it one way or another.
I started with the shots. Wowee! the effect was like night and day. For two years I was like a teenager. But then I noticed some REALLY risky (Health) behavior ( and memory gaps) and bad decisions with long-term implications(i.e judgement). So I tried stopping TRT (four years on the pumps),within four months, mood swings like menopause: snarly with co workers (not good in nursing), grumpy with everyone, switch from jovial to downcast in an instant (I’m male). Had to go back on and do an 18 mth taper, coupled with exercise. No TRT, makes exercise SO hard to do. Muscles seem so much more aware of stiffness.
The Organon group in the Netherlands were the first to isolate the hormone, identified in a May 1935 paper "On Crystalline Male Hormone from Testicles (Testosterone)".[184] They named the hormone testosterone, from the stems of testicle and sterol, and the suffix of ketone. The structure was worked out by Schering's Adolf Butenandt, at the Chemisches Institut of Technical University in Gdańsk.[185][186]
Hello – Has anybody here had their hair fall out after significantly increasing their T level? In 90 days of Clomiphene Citrate use my Total Testosterone went from 290 to 1100. and my Free T went from 50 to 202. Yes, it went way up! CC works. I have no idea why anybody would bother with gels and shots without giving this a chance. It costs almost nothing. so cheap.
We’ll be honest. Testosterone boosters don’t really boost. The best testosterone booster is like taking a multivitamin with extra herbs that might slightly and temporarily increase your testosterone levels. Like all supplements, finding the right testosterone booster means wading into a sea of ingredients, all promising to help. Of 133 testosterone boosters, we found only one with the right ingredients to help raise your testosterone levels: Beast Sports Nutrition - Super Test ($45.88 for 180 capsules, or $2.04 per day).
There is a large body of evidence linking the onset and/or progression of cardiovascular disease to low testosterone levels in men. It is now apparent that an increased cardiovascular risk and accelerated development of atherosclerosis occurs not only in elderly men or men with obesity or type 2 diabetes mellitus, but also in non-obese men with hypogonadism.14 Current best evidence from systematic review of randomized controlled trials suggests that testosterone use in hypogonadal men is relatively safe in terms of cardiovascular health and do not produce unfavorable elevations in blood pressure or glycemic control, and does not adversely effect lipid profiles.4,15
This has become a common practice despite an Institute of Medicine (IOM) report issued in 2003, indicating insufficient evidence of any benefit derived from testosterone hormone therapy to address expected symptoms of male aging.4  These studies, and 2 others (to be presented in a separate EW research brief) come on the heels of research on the efficacy of prescribing testosterone5 that appeared in the NEJM last year.
I see this is an older thread, but still very appropriate. After feeling lethargic, gaining weight, and generally having a declining sexual appetite I took some advice from a friend and got the Test check done. Turns out I was around 189, and it explained a lot. Now, I am a bigger guy, and I do hit the gym regularly, and I do push weights a lot. Big arms and chest, kinda flabby gut. Doc recommended Andro Gel. Glad I had insurance, because it is EXPENSIVE!!!!! Noticed after a week of two pumps that energy was coming back, and I could concentrate better at work. A little bit of face acne, some around shoulders, and a little on the chest. I also noticed a little acne on the contact areas on my arms where I applied it. Nothing like a teenager, but I noticed. It did help in the gym a little bit, as I would put on muscle a little faster, and kept it a bit longer. I also noticed some extra water weight gain around my gut.
Fenugreek, in the form of a capsule, testofen, or Fenugreek tea could do the trick. The fact that fenugreek increases libido is not mythology; it is backed by a clinical study which showed the libido of men aged 25-52 increased by 25%[1] on average when taking fenugreek extract for six weeks.  According to Lee Myer, of www.peaktestosterone.com fame, fenugreek will help you achieve orgasm as well, so if this is an issue for you, fenugreek may be the answer.  It’s a frustrating problem to have.
Free testosterone (T) is transported into the cytoplasm of target tissue cells, where it can bind to the androgen receptor, or can be reduced to 5α-dihydrotestosterone (DHT) by the cytoplasmic enzyme 5α-reductase. DHT binds to the same androgen receptor even more strongly than testosterone, so that its androgenic potency is about 5 times that of T.[118] The T-receptor or DHT-receptor complex undergoes a structural change that allows it to move into the cell nucleus and bind directly to specific nucleotide sequences of the chromosomal DNA. The areas of binding are called hormone response elements (HREs), and influence transcriptional activity of certain genes, producing the androgen effects.
Erectile dysfunction is a common finding in the aging male. A prevalence of over 70% was found in men older than 70 in a recent cross-sectional study (Ponholzer et al 2005). Treatment with phosphodiesterase-5 (PDE-5) inhibitors is proven to be effective for the majority of men but some do not respond (Shabsigh and Anastasiadis 2003). The condition is multi-factorial, with contributions from emotional, vascular, neurological and pharmacological factors. The concept of erectile dysfunction as a vascular disease is particularly interesting in view of the evidence presented above, linking testosterone to atherosclerosis and describing its action as a vasodilator.

“Before taking Andro400, my husband weighed 290 lbs. He's a diabetic and his blood pressure was through the roof. I purchased Andro based on the reviews, and he's lost 60 - 70 lbs! ​It's enhanced him health-wise in a lot of aspects too. He used to be depressed because of his weight. The fact that he was losing weight like crazy gave him a lot of relief. He's not depressed now, he's really happy. He's more loving. And it's so exciting for me as a wife to see him happier -- it made me happier​! ​ So I'm really grateful. Andro400 gave him a lot of ​energy ​ too because of the testosterone boost.​ The 3 main things everybody's noticing are: no more​ depression, a lot more energy and ​the huge weight loss. He went from size 42 to 38, so it's like, oh my God it's WORKING!! Trust me, we've tried a lot of other things that didn't work. And that's why I'm so excited because it's actually, literally changing our lives!”

One of the few testosterone boosters on the market to feature Eurycoma Longifolia, a patented ingredient that was developed at Massachusetts Institute of Technology (MIT) for the treatment of sexual dysfunction and male fertility, Tongkat Ali supports increased sex drive through multiple pathways, including boosting one’s free testosterone levels. Great as a standalone testosterone booster and a staple in many people’s post cycle after an anabolic cycle.


Benefits: Ashwagandha a wonderful herb originating from India is also called the Indian Ginseng because of it’s regard as a powerful aphrodisiac. Ashwagandha roots when consumed it increases sexual powers. These sexual powers include maintaining a stronger erection, longevity, enhanced sexual feeling. It also enhances fertility by increasing sperm count and quality. Ashwaganda works by reducing prolactin and neutralizing free radicals which both leads to increased testosterone levels.

With the exception of increasing my fat and cholesterol intake, my diet wasn’t that unconventional. I didn’t follow a strictly low-carb or Paleo diet because recent research has suggested that a diet high in protein and low in carbs actually causes T levels to decrease. With that said, I was judicious with the carbs. I tried to get most of my carbs from veggies and fruit, but I didn’t freak out if my wife made us spaghetti for dinner.
Thanks for reaching out buddy. Sorry to hear about your situation. First off, what I’d suggest is to forget about creams, they are a waste of money unless you are trying to moisturize your body – which I guess you’re not. As for estrogen blockers, the same goes here – but testosterone boosters on the other hand, they work with your body instead of against it to give you everything your body is missing – it sounds like it’s the missing piece to your puzzle. Bear in mind Graham, you’ll need to pay close attention to your diet – aim to cut down on refined carbohydrates and simple sugars – these are terrible for testosterone production and weight gain. If you drink more water, eat a balanced diet, and exercise occasionally while supplementing with testofuel.com you’ll soon be back on track. All the best!
Carbs play a big part in determining your Testosterone levels. Let's start with what to avoid. First, research shows that a large serving of sugar (75g of glucose), decreased Testosterone levels by as much as 25%! (25 & 26). I know this is a pretty extreme dosage, but you may want to avoid massive servings of sugar! Also, men who have Metabolic syndrome have lower Testosterone levels (27). Metabolic syndrome is often brought about by chronic high blood sugar which leads to insulin resistance.
Ginger rhizome powder was reported to posses an antioxidant and androgenic activity in doses of 50 mg/kg and 100 mg/kg daily [1]. Ginger administration significantly increased serum testosterone levels at 100 mg/kg [1]. There was also an increases in testosterone at 50 mg/kg daily but it failed to reach statistical significance [1]. A study by Kamtchouing et al. [2] also reported significantly increased serum and testicular testosterone levels as well as increase in weight of the testis and testicular cholesterol level in healthy rats. Another study using doses of 500 mg/kg and 1000 mg/kg indicated that extract of Zingiber officinale possesses pro-fertility properties [3]. Compared with the controls there was a dose and duration dependent increases in the serum testosterone levels and seminal quality [3]. At a very high dose (2000 mg/kg for 35 days), ginger led to slightly reduced weights of testes which might be due to negative feedback reaction from androgenic activity [4]. Combination of ginger and zinc appears to further increase testosterone in rats [24].
When looking for a solid natural testosterone booster, you’ll want one that has the ability to increase natural testosterone levels, increase muscular strength, improve performance and stamina, and help pack on lean muscle mass.  With a mix of key ingredients like D-AA, Tribulus, Fenugreek, and DIM, Evlution’s booster aims to take your training to the next level.  It can also help improve your sleep which is vital in allowing the body to recover from intense sessions in the gym.

However, testosterone is only one of many factors that aid in adequate erections. Research is inconclusive regarding the role of testosterone replacement in the treatment of erectile dysfunction. In a review of studies that looked at the benefit of testosterone in men with erection difficulties, showed no improvement with testosterone treatment. Many times, other health problems play a role in erectile difficulties. These can include:


Overall, few patients have a compelling contraindication to testosterone treatment. The majority of men with late onset hypogonadism can be safely treated with testosterone but all will require monitoring of prostate parameters HDL cholesterol, hematocrit and psychological state. It is also wise to monitor symptoms of sleep apnea. Other specific concerns may be raised by the mode of delivery such as local side effects from transdermal testosterone.

Hello everyone. First off, thank you Dr. Abraham Morgentaler, for the excellent and refreshing article. I do not intend to spill my guts about symptoms or values on here as it has already been done so many times over. I will say that I am an RN BSN and have been on HRT for going on 6 yrs. I live in Oklahoma and when I first started noticing symptoms I knew something was wrong and began to do research myself. With an initial level of 241 no doctor here at that time, would even consider HRT as I was only 35ish at the time.
In 1927, the University of Chicago's Professor of Physiologic Chemistry, Fred C. Koch, established easy access to a large source of bovine testicles — the Chicago stockyards — and recruited students willing to endure the tedious work of extracting their isolates. In that year, Koch and his student, Lemuel McGee, derived 20 mg of a substance from a supply of 40 pounds of bovine testicles that, when administered to castrated roosters, pigs and rats, remasculinized them.[183] The group of Ernst Laqueur at the University of Amsterdam purified testosterone from bovine testicles in a similar manner in 1934, but isolation of the hormone from animal tissues in amounts permitting serious study in humans was not feasible until three European pharmaceutical giants—Schering (Berlin, Germany), Organon (Oss, Netherlands) and Ciba (Basel, Switzerland)—began full-scale steroid research and development programs in the 1930s.
The study population in these TTrials included men aged 65 years or older with mean morning serum testosterone concentrations of 275 ng/dL or less and symptoms of impaired sexual function, physical function, or vitality. These trials were placebo-controlled and the testosterone treatment group received 1% testosterone gel at variable doses adjusted to maintain plasma testosterone at levels normal for young men (500-800 ng/dL).
February 22, 2018 - Since our last review, the manufacturers of two of our top picks have gone out of business, and some new testosterone boosters have entered the arena. We’ve updated this review to evaluate the current field of testosterone supplements, as well as beef up analysis on what kind of results you can expect from t-boosters. Our only current top pick, Beast Sports Nutrition, is a new player in the industry that contains all four of the ingredients with studies showing a positive effect on testosterone.
Testosterone is the main hormone associated with muscle mass, strength gains, and libido. But that's far from the only thing it does in the body. As Chris Lockwood, Ph.D., explains in the article "All About Testosterone," it impacts everything from mood and memory to bone health—but yes, to be clear, it also makes muscles bigger and stronger, and helps increase endurance and athletic performance.
