Cognitive abilities differ between males and females and these differences are present from childhood. In broad terms, girls have stronger verbal skills than boys who tend to have stronger skills related to spatial ability (Linn and Petersen 1985). It is thought that the actions of sex hormones have a role in these differences. Reviewing different cognitive strengths of male versus female humans is not within the scope of this article but the idea that cognition could be altered by testosterone deserves attention.

Longitudinal studies in male aging studies have shown that serum testosterone levels decline with age (Harman et al 2001; Feldman et al 2002). Total testosterone levels fall at an average of 1.6% per year whilst free and bioavailable levels fall by 2%–3% per year. The reduction in free and bioavailable testosterone levels is larger because aging is also associated with increases in SHBG levels (Feldman et al 2002). Cross-sectional data supports these trends but has usually shown smaller reductions in testosterone levels with aging (Feldman et al 2002). This is likely to reflect strict entry criteria to cross-sectional studies so that young healthy men are compared to older healthy men. During the course of longitudinal studies some men may develop pathologies which accentuate decreases in testosterone levels.

Vitamin D, a steroid hormone, is essential for the healthy development of the nucleus of the sperm cell, and helps maintain semen quality and sperm count. Vitamin D also increases levels of testosterone, which may boost libido. In one study, overweight men who were given vitamin D supplements had a significant increase in testosterone levels after one year.5

The one side effect that no one talks about is psychological for me. Because I am 67 years old and suddenly look, feel and act 37 I only want to be around younger people. I have no use associating with people my own age. I have nothing in common and even look different. This year at my class reunion was a glaring example…..no doubt I looked younger than anyone, but it is sooo much more than just very that. My customers are young, all my girlfriends and associates. This all has a large effect on my mind. It’s hard to grasp suddenly looking and acting 30 years younger than your friends. My mind is so confused about how old I really am. I do a lot of adrenalin sports for my age snow ski, wake-surf, wake-board, scuba dive and it is no doubt just a matter of time till I get hurt doing these wild sports. In my mind I’m 37 so I think it’s all normal. This whole experience has been incredible and very positive with the only one psychological effect and no other physical side effect.
Like most supplements, Beast Sports contains several ingredients with little research about their long-term effects. WebMD describes Suma powder, Rhodiola Rosea, Cissus quadrangularis, Tribulus extract, and ashwagandha extract as possibly safe when taken for a short period of time (usually around 6-10 weeks). However, their long-term safety remains unknown. It also has a few ingredients, like cyanotis vaga root, safed musli, and polygonum cispidatum root extract for which there is a lack of data on even short term safety.
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).
A team led by Dr. Joel Finkelstein at Massachusetts General Hospital investigated testosterone and estradiol levels in 400 healthy men, 20 to 50 years of age. To control hormone levels, the researchers first gave the participants injections of a drug that suppressed their normal testosterone and estradiol production. The men were randomly assigned to 5 groups that received different amounts (from 0 to 10 grams) of a topical 1% testosterone gel daily for 16 weeks. Half of the participants were also given a drug to block testosterone from being converted to estradiol.
Male hypogonadism becomes more common with increasing age and is currently an under-treated condition. The diagnosis of hypogonadism in the aging male requires a combination of symptoms and low serum testosterone levels. The currently available testosterone preparations can produce consistent physiological testosterone levels and provide for patient preference.

If a young man's low testosterone is a problem for a couple trying to get pregnant, gonadotropin injections may be an option in some cases. These are hormones that signal the body to produce more testosterone. This may increase the sperm count. Hedges also describes implantable testosterone pellets, a relatively new form of treatment in which several pellets are placed under the skin of the buttocks, where they release testosterone over the course of about three to four months. Injections and nasal gels may be other options for some men.

How alpha are you? Well, how many shakes of hot sauce can you handle? A recent study from France found men who have a taste for spicy foods tend to have higher testosterone levels than those who can’t handle the heat. Of the 114 male participants surveyed, researchers saw a clear correlation between frequent hot-sauce usage and higher T-levels. Study authors suggest the findings may be due in part to capsaicin—the fiery compound in chili pepper that previous studies have associated with increased testosterone levels. In animal studies, capsaicin has also shown to increase the size of sex organs, while simultaneously decreasing belly fatbelly fat. Yowza!


As blood levels of testosterone increase, this feeds back to suppress the production of gonadotrophin-releasing hormone from the hypothalamus which, in turn, suppresses production of luteinising hormone by the pituitary gland. Levels of testosterone begin to fall as a result, so negative feedback decreases and the hypothalamus resumes secretion of gonadotrophin-releasing hormone. 
Infertility in men and women Infertility or a couple being unable to conceive a child can cause significant stress and unhappiness. There are numerous reasons for both male and female infertility but many ways in which medical assistance can overcome problems that people may face. Everything concerning infertility is discussed and explained here. Read now
The steroid hormone known as dehydroepiandrosterone, DHEA, plays an important role in sexual behavior, mental health and muscle growth. Your body uses this hormone to make sex steroids. Thus, taking a DHEA supplement should increase your circulating testosterone. A 2018 paper in the International Journal of Sports Medicine explored this possibility in athletic women.
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!
The sex hormone testosterone is far more than just the stuff of the alpha male's swagger. Though it plays a more significant role in the life of the biological male, it is actually present in both sexes to some degree. Despite popular perceptions that testosterone primarily controls aggression and sex drive—although it does play a role in both of those things—research has shown that individual levels of testosterone are also correlated with our language skills and cognitive abilities. Testosterone occurs in the body naturally, but can be administered as a medication, too: its most common uses are in the treatment of hypogonadism and breast cancer, as well as in hormone therapy for transgender men.
Caffeine. Use caffeine moderately. Too much of the jittery juice increases cortisol, which decreases testosterone. Moreover, consuming caffeine late in the day hurts sleep, which lowers testosterone production. But one recent study indicates that caffeine consumed before working out may boost testosterone levels and help you exercise more efficiently. During my experiment I popped a piece of caffeinated gum five minutes before my workouts. Each piece had 100 mg of caffeine, about the same amount in a cup of coffee. That was usually it for my caffeine intake that day.
I have been on TRT for over 8 years now. I feel GREAT! I read all these studies, hear in the news, and see all these dumb lawsuit commercials about testosterone causing cardiovascular events, blood clots and many other things. If anyone takes the time to do the due diligence and read the studies the picture becomes very clear. Unless you monitor all the other hormones, specifically, Estradiol, DHT, Pregenolone, Total Testosterone, Free Direct Testosterone, and DHEAS you are playing a deadly game. The reason is you must give something to control the pathways of T conversion into estradiol and or DHT. The vast majority of the studies used nothing to control those pathways and they gave men way, way more T than they needed to start with. They also gave forms of T that are not acceptable. Especially the oral version.
Of course, testosterone’s primary function is to bring about secondary sexual characteristics in men. A healthy dose of testosterone is shown to treat conditions such as impotence. Men with fertility issues benefit from increased levels of testosterone in the body. The aging process slows down the rate of testosterone production by the adrenals and testes. It is irreversible and one of the only means to mediate the effects of low testosterone concentration is to include testosterone boosting agents in your regimen.
There are several supplements on the market claiming to be natural testosterone boosters. I get these sorts of things in the mail all time. The companies that produce these products claim that the herbs (typically stinging nettle and tribulus) in their pills increase free testosterone by reducing SHBG. They also throw in some B vitamins for “increased energy and vitality.”
For people who are worried about low or high testosterone, a doctor may perform a blood test to measure the amount of the hormone in the patient's blood. When doctors find low-T, they may prescribe testosterone therapy, in which the patient takes an artificial version of the hormone. This is available in the following forms: a gel to be applied to the upper arms, shoulders or abdomen daily; a skin patch put on the body or scrotum twice a day; a solution applied to the armpit; injections every two or three weeks; a patch put on the gums twice a day; or implants that last four to six months.

This is one of the most controversial recommendations I make, but it shouldn’t be. It’s no different than using thyroid medication. If your levels are low, and the other techniques here don’t work, use TRT. You will like your life again. If your levels are low, bioidentical testosterone will make you live longer and better, provided you use it right.
“The Andro 400 has been a plus to my daily requirements of energy, stamina and weight loss. I have seen a noticeable reduction in my waistline from a 40" waist to a 37" waist. I am 6'6" and weighed 252, I now weigh 238 and feel much better. Without too much information, my sex drive and performance has been positively enhanced with greater sensitivity and stamina during those intimate times with my wife. Greater sensation, pleasure and results are evident.” 

Testosterone improves not just your sex drive, but it also enhances exercise drive, energy for work, mental sharpness, muscle repair, and revs your metabolism to help with weight control. Although improving testosterone levels has not yet been shown to increase lifespan, having a healthy testosterone level improves quality of life for both men and women.
“I can't tell you how good the product is! I'm in the best shape of my life. I used to take blood pressure medication and I don't even take that anymore. It's changed every aspect of my life. I was a 40 waist and I'm down to a 36. I'm 54 years old, and people tell me I look better than I ever have, and I look like I'm in my early 40s! And I'm telling you it's the Andro. This product is so much better than even the advertisements! From taking Andro400 I immediately notice a burst of energy . . . and my skin color, my sexual advancements, my energy, plus the weight loss, the toning of the body, and the increase strength and endurance . . . it's like night and day where I was then and where I am now, and Andro400 has made the difference. And my wife also takes it, 1 pill every other day, and she has experienced an amazing transformation in her body alone, with her hair, her complexion, and as well as in the gym. It's an outstanding product. My customers, my friends, my family, everybody is noticing the difference!”
While researchers in Brisbane, Australia, found that while Testofen (“a standardized [fenugreek] extract and mineral formulation”) significantly improved the sexual arousal, orgasm, and the general quality of life of participants, it did not remarkably increase testosterone above normal levels. Participants who took Testofen were more satisfied with their energy, well-being, and muscle strength than those who took the placebo.
In this article, testosterone-replacement therapy refers to the treatment of hypogonadism with exogenous testosterone — testosterone that is manufactured outside the body. Depending on the formulation, treatment can cause skin irritation, breast enlargement and tenderness, sleep apnea, acne, reduced sperm count, increased red blood cell count, and other side effects.
Men who watch a sexually explicit movie have an average increase of 35% in testosterone, peaking at 60–90 minutes after the end of the film, but no increase is seen in men who watch sexually neutral films.[43] Men who watch sexually explicit films also report increased motivation, competitiveness, and decreased exhaustion.[44] A link has also been found between relaxation following sexual arousal and testosterone levels.[45]
That said, keep in mind that using leucine as a free form amino acid can be highly counterproductive as when free form amino acids are artificially administrated, they rapidly enter your circulation while disrupting insulin function, and impairing your body's glycemic control. Food-based leucine is really the ideal form that can benefit your muscles without side effects.

A meta-analysis of nine randomized controlled trials [31] evaluated effects of ginger on net changes in blood glucose and lipid concentrations (total cholesterol, triglyceride, low-density lipoprotein cholesterol, high density lipoprotein cholesterol).  In a total of 609 adults with T2DM or hyperlipidemia, ginger supplementation led to significant reductions in plasma levels of total cholesterol, triglycerides, and blood glucose, but non-significant reduction in LDL-c levels.
Shilajit in its natural state has no chemical definition. In order to yield a consistent and efficacious form of shilajit, the shilajit is obtained from carefully selected rocks and is put through a patented technology where it is purified and standardized. This form of shilajit is now assured of optimal levels of bioactive components such as fulvic acid and dibenzo-pyrones, and is known as the patented PrimaVie.

Ashwagandha is shown to be effective at reducing cortisol which in turn helps with testosterone production. There are also numerous studies showing the effects on improving testosterone in infertile men (ref 80).  If you are using the Aggressive Strength product you don't need to supplement with ashwagandha as it's included in the test booster formula. Likewise if you're using Tian Chi (my daily herb drink).
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).

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!”

So much to say, take a look at excelmale.com. it is a resource for men like us that give answers, science and dialogue which addresses our questions. It’s a great resource for men like us. Also, I would say to eliminate blue light before bed from tv and pc screens. Simply use blue light blocking glasses or F.lux from the play store. Also get outside in the sun in the AM. The goal is to restore the circadian rhythm which impacts hormone productiion.

Boron, a mineral, keeps the cell walls of plants strong. Eating dried fruits and nuts gives you abundant amounts of boron. You can also take boron supplements. It's important to keep your daily boron intake at less than 20 mg, however, according to a current factsheet available from the U.S. National Library of Medicine. High doses of boron can cause serious side effects such as skin inflammation and peeling, irritability, tremors or depression.

For this reason I recommend doing your own research on this supplement before taking it. 5g of ground up dried powder is what was used in the studies. I recommend taking 1-2 capsules of the concentrated form from Paradise Herbs. Alternatively, the Aggressive Strength Test Booster also has MP in its formula so you may prefer to use that blend instead. 
Testosterone is a steroid from the androstane class containing a keto and hydroxyl groups at the three and seventeen positions respectively. It is biosynthesized in several steps from cholesterol and is converted in the liver to inactive metabolites.[5] It exerts its action through binding to and activation of the androgen receptor.[5] In humans and most other vertebrates, testosterone is secreted primarily by the testicles of males and, to a lesser extent, the ovaries of females. On average, in adult males, levels of testosterone are about 7 to 8 times as great as in adult females.[6] As the metabolism of testosterone in males is greater, the daily production is about 20 times greater in men.[7][8] Females are also more sensitive to the hormone.[9]

Unlike injection or ingestion of anabolic steroids, the use of testosterone boosters is relatively safe for daily consumption. In order to ward off any negative side effects, it is best to take a rest after finishing a bottle of your preferred testosterone booster. This will allow the body to relax after months of taking supplements that increase testosterone levels. This practice effectively cleans the body as well.
Testosterone is only one of many factors that influence aggression and the effects of previous experience and environmental stimuli have been found to correlate more strongly. A few studies indicate that the testosterone derivative estradiol (one form of estrogen) might play an important role in male aggression.[66][71][72][73] Studies have also found that testosterone facilitates aggression by modulating vasopressin receptors in the hypothalamus.[74]

That said, magnesium is one of a few ingredients demonstrated to impact testosterone levels. Researchers at Italy’s University of Palermo found that magnesium improved participants’ anabolic hormone status — including their testosterone levels. In a follow-up study, they confirm that even adjusting for age differences in their participant group, “magnesium was positively associated with total testosterone.” They propose that magnesium supplementation might help improve muscle performance in aging men — a group particularly vulnerable to declining/low testosterone levels. Outside of Italy, researchers at Turkey’s Selçuk University found that magnesium supplementation increased testosterone levels for both athletes and more sedentary men alike.

The testosterone booster pills are effective from 4 to 8 hours. To maintain testosterone levels high during the whole day, you need a multiple daily dosing regimen. 2-times daily dosing still not always can improve hormone production to the greatest extent. 3-4-times daily dosing is the best solution to make your body normalize testosterone synthesis and prevent it from decreasing before you take another pill. Don’t forget that the regularity of daily supplement intake is crucial if you really aspire to give a boost to hormone production.
It doesn’t get more natural than getting a good night’s sleep. Research published in the Journal of the American Medical Association showed that lack of sleep can greatly reduce a healthy young man’s testosterone levels. That effect is clear after only one week of reduced sleep. Testosterone levels were particularly low between 2 and 10 p.m. on sleep-restricted days. Study participants also reported a decreased sense of wellbeing as their blood testosterone levels dropped.
• In a trial of men with anemia, 58% percent were no longer anemic after a year of therapy, compared to 22% who received a placebo. In addition, testosterone therapy was associated with higher hemoglobin levels. Hemoglobin is a protein in the blood that carries oxygen from the lungs to other areas of the body. It also brings carbon dioxide back to the lungs.
I am 50 yrs old. I tried to go the route my urologist provide of 50mgs of injectable test weekly. No man can live on that dose. For the past five years I have self administered injectable cyponate at the rate of 250 mgs to 750 mgs weekly. Non stop , no breaks. I have polycythemia from these injections. I give blood every 8 weeks to combat this. I have administered 10 X the recommended dose with no bad side effects. I get full blood work done yearly. Doctors are so scared they will get sued if something happens that they wont give you enough. Its a shame.

The sex hormone testosterone is far more than just the stuff of the alpha male's swagger. Though it plays a more significant role in the life of the biological male, it is actually present in both sexes to some degree. Despite popular perceptions that testosterone primarily controls aggression and sex drive—although it does play a role in both of those things—research has shown that individual levels of testosterone are also correlated with our language skills and cognitive abilities. Testosterone occurs in the body naturally, but can be administered as a medication, too: its most common uses are in the treatment of hypogonadism and breast cancer, as well as in hormone therapy for transgender men.

Male hypogonadism is a clinical syndrome caused by a lack of androgens or their action. Causes of hypogonadism may reflect abnormalities of the hypothalamus, pituitary, testes or target tissues. Increases in the amount of testosterone converted to estrogen under the action of the enzyme aromatase may also contribute to hypogonadism. Most aspects of the clinical syndrome are unrelated to the location of the cause. A greater factor in the production of a clinical syndrome is the age of onset. The development of hypogonadism with aging is known as late-onset hypogonadism and is characterised by loss of vitality, fatigue, loss of libido, erectile dysfunction, somnolence, depression and poor concentration. Hypogonadal ageing men also gain fat mass and lose bone mass, muscle mass and strength.
