Low testosterone levels can cause mood disturbances, increased body fat, loss of muscle tone, inadequate erections and poor sexual performance, osteoporosis, difficulty with concentration, memory loss and sleep difficulties. Current research suggests that this effect occurs in only a minority (about 2%) of ageing men. However, there is a lot of research currently in progress to find out more about the effects of testosterone in older men and also whether the use of testosterone replacement therapy would have any benefits.
It is now well-established that elderly men with type 2 diabetes mellitus have reduced levels of testosterone (Barrett-Connor 1992; Betancourt-Albrecht and Cunningham 2003). It is known, however, that obese men and diabetic men have reduced levels of SHBG (Barrett-Connor 1990) which could account for the lower total testosterone levels found in diabetic men. Dhindsa et al (2004) studied 103 male patients who had type 2 diabetes mellitus using free testosterone (done by equilibrium dialysis) or calculated free testosterone which takes SHBG levels into account. Of the 103 patients, 57 had free testosterone by equilibrium dialysis and of these, 14 (25%) had a free T below 0.174 nmol/L and were considered hypogonadal. Using a total testosterone of 10.4 nmol/L (300ng/dl) as the lower limit of normal 45 patients (43%) were in the hypogonadal range. They also found that LH and FSH concentrations were significantly lower in the hypogonadal group. The authors thus concluded that hypogonadotropic hypogonadism was a common finding in type 2 diabetes irrespective of glycemic control, duration of disease or the presence of complications of diabetes or obesity.
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.

Studies conducted in rats have indicated that their degree of sexual arousal is sensitive to reductions in testosterone. When testosterone-deprived rats were given medium levels of testosterone, their sexual behaviors (copulation, partner preference, etc.) resumed, but not when given low amounts of the same hormone. Therefore, these mammals may provide a model for studying clinical populations among humans suffering from sexual arousal deficits such as hypoactive sexual desire disorder.[37]

My question is in two parts, I am looking for energy and some muscle build but only do push ups and sit ups so not looking for massive results. I am diabetic and I am wanting to get a testosterone booster to have more energy for daily use not so much for help in the bedroom but I would not mind if it helps out. Would I be able to take it not just for a certain product but any testosterone booster? The other question is does it help with any form of muscle growth, again not anything big but some? I would appreciate any advice or information you can give me.

Testosterone is an important hormone for both men and women. Even though it’s often associated with a man’s libido, testosterone occurs in both sexes from birth. In females, it plays a part in sexual drive, energy, and physical strength. In males, it stimulates the beginning of sexual development and helps maintain a man’s health throughout his life.

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.
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.
The reasons for considering such therapy become evident from the many associations, indicated above, that reduced testosterone has with a variety of both physiological functions (bone metabolism, muscle mass, cognitive function, libido, erectile function) and pathophysiological states (metabolic syndrome, diabetes mellitus, obesity, insulin resistance, autoimmune disease). Although a definitive long-term, large scale placebo-controlled double-blind study of testosterone therapy in the aging male has not yet been carried out, multiple shorter-term trials have suggested improvement by testosterone with a resultant enhancement of muscle mass, bone density, libido, erectile function, mood, motivation and general sense of well-being.

Testosterone is a hormone with multifaceted physiological functions and multiple associations with pathophysiological states. It is an important hormone in male reproductive and metabolic function from intrauterine life to old age. In severe or classical hypogonadal states there is little controversy about the need to administer testosterone by an intramuscular, oral or transdermal formulation. There is controversy about making the diagnosis in the less severe cases of hypogonadism associated with the aging male but the current evidence suggests that this is efficacious in appropriately selected men and that there is little if any risk in giving aging symptomatic hypogonadal men a 6 month trial of therapy to determine whether symptoms will improve.
“This study establishes testosterone levels at which various physiological functions start to become impaired, which may help provide a rationale for determining which men should be treated with testosterone supplements,” Finkelstein says. “But the biggest surprise was that some of the symptoms routinely attributed to testosterone deficiency are actually partially or almost exclusively caused by the decline in estrogens that is an inseparable result of lower testosterone levels.”
We should probably start with the elephant in the room: do these supplements increase testosterone? The answer is probably yes. There are some ingredients that help convince your body to produce more testosterone, but there’s a catch. Testosterone boosters aren’t actually great at boosting; that is, at pushing your testosterone levels above your healthy, normal balance. Boosters typically act more like restorers — helping bring low testosterone levels back to that healthy equilibrium rather than boosting you above normal testosterone levels. Just like how if you have anemia, taking a vitamin B12 supplement can help restore your energy and reduce fatigue, but if your B12 levels are good, a supplement won’t give you super energy levels to stay awake for three days — your body will likely just process (read: pee) out the extra.
Before the ready availability of non-injectible testosterone preparations, and because of their ease of administration by the oral route, 17-alkylated steroids were popular surrogate agents for testosterone. These substances, however, were capable of inducing several risk factors for coronary artery disease (Kopera 1993; Hall and Hall 2005) and as a consequence, particularly after the revelations of extensive 17-alkylated anabolic steroid abuse by athletes, testosterone, became unjustly incriminated. The evidence, however, tends to suggest just the opposite; testosterone may even be cardioprotective. Dunajska and colleagues have demonstrated that when compared to controls, men with coronary artery disease tend to have: lower total testosterone levels and free androgen indices, more abdominal fat, higher blood sugar and insulin levels (Dunajska et al 2004).

Overall there is evidence that testosterone treatment increases lean body mass and reduces obesity, particularly visceral obesity, in a variety of populations including aging men. With regard to muscle changes, some studies demonstrate improvements in maximal strength but the results are inconsistent and it has not been demonstrated that these changes lead to clinically important improvements in mobility, endurance or quality of life. Studies are needed to clarify this. Changes in abdominal obesity are particularly important as visceral fat is now recognised as predisposing the metabolic syndrome, diabetes and cardiovascular disease.
Puberty occurs when there is an “awakening” of the hypothalamic-pituitary axis. The hypothalamus increases its secretion of gonadotropin releasing hormone (GnRH) which in turn stimulates the release of luteinizing hormone (LH) and follicle stimulating hormone (FSH). This leads to a significant increase in the production of testicular testosterone and the induction of the well-known secondary sex characteristics associated with puberty: growth spurt, increased libido, increased erectile function, acne, increased body hair, increased muscle mass, deepening of the voice, spermatogenesis, gynecomastia (usually transient).

The rise in testosterone levels during competition predicted aggression in males but not in females.[86] Subjects who interacted with hand guns and an experimental game showed rise in testosterone and aggression.[87] Natural selection might have evolved males to be more sensitive to competitive and status challenge situations and that the interacting roles of testosterone are the essential ingredient for aggressive behaviour in these situations.[88] Testosterone produces aggression by activating subcortical areas in the brain, which may also be inhibited or suppressed by social norms or familial situations while still manifesting in diverse intensities and ways through thoughts, anger, verbal aggression, competition, dominance and physical violence.[89] Testosterone mediates attraction to cruel and violent cues in men by promoting extended viewing of violent stimuli.[90] Testosterone specific structural brain characteristic can predict aggressive behaviour in individuals.[91]
Important future developments will include selective androgen receptor modulators (SARMs). These drugs will be able to produce isolated effects of testosterone at androgen receptors. They are likely to become useful clinical drugs, but their initial worth may lie in facilitating research into the relative importance of testosterone’s action at the androgen receptor compared to at other sites or after conversion to other hormones. Testosterone will remain the treatment of choice for late onset hypogonadism for some time to come.
Lean beef, chicken, fish, and eggs are some of your options. Tofu, nuts, and seeds have protein, too. Try to get about 5 to 6 ounces per day, although the ideal amount for you depends on your age, sex, and how active you are. When you don't eat enough of these foods, your body makes more of a substance that binds with testosterone, leaving you with less T available to do its job.
This paper will aim to review the current evidence of clinical effects of testosterone treatment within an aging male population. As with any other clinical intervention a decision to treat patients with testosterone requires a balance of risk versus benefit. We shall try to facilitate this by examining the effects of testosterone on the various symptoms and organs involved.
The hormone also plays a role in sex drive, sperm production, fat distribution, red cell production, and maintenance of muscle strength and mass, according to the Mayo Clinic. For these reasons, testosterone is associated with overall health and well-being in men. One 2008 study published in the journal Frontiers of Hormone Research even linked testosterone to the prevention of osteoporosis in men.
Dr. Anthony’s Notes: I use Maca often in cycles throughout the year. I typically buy the raw Maca powder, which has a VERY “dirt-like” earthy taste. Beware if you are a bit squeamish on tastes! How To Take Maca: 1500-3000mg of Maca powder is a typical dosage take daily alongside food. From personal experience, I've found that it’s best to buy the Maca powder as a standalone supplement and throw it into a blended protein shake to mask the taste.

This being my initial use of product I do find an overall improvement in mind and body "maleness" related to focused goal and strength improvements. Has it turned me into a super stud..no, but at a recent 60th birthday, increased desire has added to performance and that is what I was looking for.I have reinstated diet and exercise that also has made physical and mental health achievements Will finish current bottle, and evaluate overall products worth once completed. Further evaluation pending...
