The brain is also affected by this sexual differentiation;[13] the enzyme aromatase converts testosterone into estradiol that is responsible for masculinization of the brain in male mice. In humans, masculinization of the fetal brain appears, by observation of gender preference in patients with congenital diseases of androgen formation or androgen receptor function, to be associated with functional androgen receptors.[99]

Everytime you add Testosterone to your system, be it naturally through producing in the testis, injected, oral, or dermal you will receive a spike in your blood levels. Estrogen is mainly created in men by an action of an enzyme called Aromatase. Aromatase floats around and binds to Testosterone and converts it to Estrogen. When you spike your T your E will follow in this way. The obvious and detrimental effects to many of the already estrogen dominant hypogonadal men will be inappropriate over stimulation of the estrogen receptors in the body. Gynecomastia, fluid retention, weight gain, brain fog, erratic emotions, depression, ect. Higher levels of Estrogen cause SHBG to be created. SHBG binds to Testosterone and transports it to the liver for disposal. On top of this Estrogen can bind to your androgen receptors causing Testosterone to float around with no where to go. If you are taking shots or gel or cream and feel little to no effect even though it’s technically raised your T blood ranges, you now have an multiple answers for why you little to nothing or feel even worse. This has been known for years that you must be prepared to control Estrogen. An Aromatase Inhibitor (AI) or anti estrogen medication (Clomiphene, Tamoxifen) is needed to stop the estrogen from getting out of control. By taking an Aromatase inhibitor and monitoring your E2 levels you can easily control Estrogen, Aromatase, and SHBG from getting out of hand and free up those blocked androgen receptors so you can now reap the benefits of elevating T to a healthy level. If your Doctor is not testing your E2(aka Estrogen, Estradiol) levels before and during talks and administration of TRT or will never prescribe an AI then you shouldn’t be following his advice at all and will be harmed by Testosterone usage. This may sound complicated but in the end it’s simple. Elevate Testosterone. Control Estrogen. Only two medications needed. Don’t settle.
Consuming high amounts of sugary foods raises your blood glucose levels, which causes your body to release insulin as a response to the raised blood glucose levels. If not managed correctly, the body begins to develop a tolerance to insulin and cannot absorb the sugars in the blood stream as it used to, causing you to become insulin resistant. Being insulin resistant releases cortisol, and as you know, cortisol has extremely negative effects, lowering testosterone by quite a bit.

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.
When patients ask about risks, I remind them that they already have testosterone in their system and that the goal of testosterone treatment is to restore its concentration back to what it was 10 or 15 years previously. And the molecule itself that we give is identical to the one that their bodies make naturally, so in theory, everything should be hunky-dory. But in practice, there are always some curveballs.

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.

Men who start using the gels have to come back in to have their testosterone levels measured again to make sure they’re absorbing the right amount. Our target is the mid to upper range of normal, which usually means around 500 to 600 ng/dl. The concentration of testosterone in the blood actually goes up quite quickly, within a few doses. I usually measure it after two weeks, though symptoms may not change for a month or two.
Herein lies the problem.  DHT is an extremely powerful androgen, significantly more potent than testosterone.  Somehow, fenugreek causes increases in muscle mass and libido while reducing DHT.  I often argue on the site that it is not exactly increased testosterone that you want.  You want the blessings of a high testosterone level: physical fitness, libido, and high energy levels.  If fenugreek can bestow these upon you, why do you need the testosterone?

“What on earth do you mean?” Well, I don’t literally mean taking it to the compound. What I mean to say is that you should be incorporating the three most important compound exercises into your routine: bench press, squats, and deadlifts. In case you didn’t know, by training large muscle groups your body releases more testosterone. When you do these three lifts, and perform them properly, then you’ll reap the benefits of not only muscle gains, but also that of an increased release of testosterone and growth hormone.


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.

I was born with a rare genetic disorder called Klinefelter’s syndrome. My parents actually were known about my condition prior to birth. I’m 25 years old and have been on TRT since 8th grade. It’s a permanent part of life and essential to ultimate happiness, motivation, and the pursuit of bigger and better things. I currently face problems at this time in life due to the endocrinologists. It seems when I bring a problem or question to them, they don’t take charge and figure it out. There all pushed off to the side and left for no one; so now I’ve gotten rid of them and I’m in pursuit of a doctor who will improve the quality of my life. Also with my last doctor I was able to retrieve enough testosterone to perform my out ethical experiment with Testosterone. I injected myself every 5 days for a period of 3 months at the dosage of .75ml. The outcome was amazing. My mind, body, and spirit were one. The energy was phenomenal and in demand. I was able to pursue my endeavors with the energy provided, I was able to think about running and exercising and then put that thought into action. I took extensive notes in the form of a journal to create the ultimate needed dosage for myself. The only reason it ended in three months, was due to no more medicine. It had to be done. Now I’m off to find a doctor to work with me.
Growth of spermatogenic tissue in testicles, male fertility, penis or clitoris enlargement, increased libido and frequency of erection or clitoral engorgement occurs. Growth of jaw, brow, chin, and nose and remodeling of facial bone contours, in conjunction with human growth hormone occurs.[21] Completion of bone maturation and termination of growth. This occurs indirectly via estradiol metabolites and hence more gradually in men than women. Increased muscle strength and mass, shoulders become broader and rib cage expands, deepening of voice, growth of the Adam's apple. Enlargement of sebaceous glands. This might cause acne, subcutaneous fat in face decreases. Pubic hair extends to thighs and up toward umbilicus, development of facial hair (sideburns, beard, moustache), loss of scalp hair (androgenetic alopecia), increase in chest hair, periareolar hair, perianal hair, leg hair, armpit hair.
Caffeine: While caffeine can’t ramp up testosterone directly, it can help you put in the quality work in the gym that will spike your T. One International Journal of Sports Nutrition and Exercise Metabolism study, for instance, found that athletes who consumed caffeine before training lifted more—and experienced a greater subsequent lift in testosterone—than those who took a placebo.
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

If you do take DAA I recommend cycling it (i.e. 5 days on, 2 off, over 4 weeks then 4 weeks off). And taking it with an aromatase inhibitor (which ensures the aspartic acid doesn’t get converted to estrogen). Especially as more studies are coming out showing the increase in testosterone is limited to a week or two before it drops back to normal levels.
Some studies have looked at testosterone therapy and cognition. Although the findings weren’t definitive, there was some evidence of cognitive improvement. Other studies have shown that it improves mood. Testosterone therapy has also been shown to be effective in the treatment of osteoporosis and in increasing muscle bulk and strength. [See “Testosterone’s impact on brain, bone, and muscle,” above.]
There are positive correlations between positive orgasm experience in women and testosterone levels where relaxation was a key perception of the experience. There is no correlation between testosterone and men's perceptions of their orgasm experience, and also no correlation between higher testosterone levels and greater sexual assertiveness in either sex.[34]

If testosterone deficiency occurs during fetal development, then male characteristics may not completely develop. If testosterone deficiency occurs during puberty, a boy’s growth may slow and no growth spurt will be seen. The child may have reduced development of pubic hair, growth of the penis and testes, and deepening of the voice. Around the time of puberty, boys with too little testosterone may also have less than normal strength and endurance, and their arms and legs may continue to grow out of proportion with the rest of their body.
In a recent study of male workers, men with low testosterone levels had an increased chance of severe erectile dysfunction (Kratzik et al 2005), although such a link had not been found previously (Rhoden et al 2002). Certainly erectile dysfunction is considered part of the clinical syndrome of hypogonadism, and questions regarding erectile dysfunction form part of the clinical assessment of patients with hypogonadism (Morley et al 2000; Moore et al 2004).
Testosterone was first used as a clinical drug as early as 1937, but with little understanding of its mechanisms. The hormone is now widely prescribed to men whose bodies naturally produce low levels. But the levels at which testosterone deficiency become medically relevant still aren’t well understood. Normal testosterone production varies widely in men, so it’s difficult to know what levels have medical significance. The hormone’s mechanisms of action are also unclear.
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.
For men with low blood testosterone levels, the benefits of hormone replacement therapy usually outweigh potential risks. However, for most other men it's a shared decision with your doctor. It offers men who feel lousy a chance to feel better, but that quick fix could distract attention from unknown long-term hazards. "I can't tell you for certain that this raises your personal risk of heart problems and prostate cancer, or that it doesn't," Dr. Pallais says.

Fenugreek is often found in Indian, Turkish, and Persian cuisine. Multiple studies have found it to improve testosterone levels, and in particular, sexual performance. Scientists at Babu Banarasi Das University and King George’s Medical University in India have found that fenugreek improved testosterone levels. Testosterone levels increased for 90% of the volunteers, sperm morphology (the size and shape of sperm) improved for 14.6%, and more than 50% of volunteers experienced improvements in mental alertness, mood, and libido.
Insulin causes lower Testosterone levels, so go easy on the carbs and eat more protein right? Well you need to be careful with protein consumption – Excess protein without fat can also cause insulin spikes. So go easy on that chicken breast with a side of egg white omelets washed down with a protein shake. From an insulin point of view you may as well drink a can of soda with some aminos acid! So what should you do? Eat more fat.
