Fatherhood decreases testosterone levels in men, suggesting that the emotions and behavior tied to decreased testosterone promote paternal care. In humans and other species that utilize allomaternal care, paternal investment in offspring is beneficial to said offspring's survival because it allows the parental dyad to raise multiple children simultaneously. This increases the reproductive fitness of the parents, because their offspring are more likely to survive and reproduce. Paternal care increases offspring survival due to increased access to higher quality food and reduced physical and immunological threats.[60] This is particularly beneficial for humans since offspring are dependent on parents for extended periods of time and mothers have relatively short inter-birth intervals.[61] While extent of paternal care varies between cultures, higher investment in direct child care has been seen to be correlated with lower average testosterone levels as well as temporary fluctuations.[62] For instance, fluctuation in testosterone levels when a child is in distress has been found to be indicative of fathering styles. If a father's testosterone levels decrease in response to hearing their baby cry, it is an indication of empathizing with the baby. This is associated with increased nurturing behavior and better outcomes for the infant.[63]
The potential downside of this positive feedback loop, Coates argues, is that testosterone levels can eventually surge past optimal levels and have the opposite effect – leading to overconfidence and poor decision-making. When this happens to animals, Coates, observed, they “go out in the open, pick too many fights [and] patrol areas that are too large…Risk taking becomes risky behaviour.”

Recently, a panel with cooperation from international andrology and urology societies, published specific recommendations with regard to the diagnosis of Late-onset Hypogonadism (Nieschlag et al 2005). These are summarized in the following text. It is advised that at least two serum testosterone measurements, taken before 11 am on different mornings, are necessary to confirm the diagnosis. The second sample should also include measurement of gonadotrophin and prolactin levels, which may indicate the need for further investigations for pituitary disease. Patients with serum total testosterone consistently below 8 nmol/l invariably demonstrate the clinical syndrome of hypogonadism and are likely to benefit from treatment. Patients with serum total testosterone in the range 8–12 nmol/l often have symptoms attributable to hypogonadism and it may be decided to offer either a clinical trial of testosterone treatment or to make further efforts to define serum bioavailable or free testosterone and then reconsider treatment. Patients with serum total testosterone persistently above 12 nmol/l do not have hypogonadism and symptoms are likely to be due to other disease states or ageing per se so testosterone treatment is not indicated.
Hello..was prescribe andro gel 1.62 for about 2 years..borderline low..At time 54 year old now 57..a year ago switched doctors..new doctor would not prescribe andro gel..without me stopping use and then being checked after 6 months..it’s been a year..by the way felt great while on it much more energy. .did notice some hair receding. .but felt stronger..my question is..by using andro gel ..did I turn off my body’s natural ability to make testosterone as using andro gel..if so what do I need to do too turn my body on if my doctor does not renew therapy. .by way the past without andro gel…little too no energy..weight gain of 40 lbs..especially around the belly..thank you for your time and reply
The regular intake of testosterone boosters is known for the high level of safety comparing to the hormone injections and the use of illegal steroids. But still to protect yourself against any possible adverse reactions, you should remember that the supplementation can’t be continuous. The breaks from time to time are required. Such an approach to the use of boosters is healthy and best-working if you aspire to enhance own hormone production without any harm.
It goes without saying that what you eat significantly influences your hormone balance and body composition. This is nothing new. There are countless athletes and bodybuilders who are paying a close attention to what they eat for a reason. For example, if you consume a lot of so-called junk food, then you inevitably end up with a poor nutritional profile. In plain English, you can forget about a six-pack and the high testosterone.

55+ million men in america between 40 and 70 years of age is a large enough group to warrant interest in a thorough study of the aged male delivery system and other sex related issues. There is a good chance there are 55 million women out there wishing for some kind of help also. Those are significant numbers, about 1/3 of the total population and the lions share of the income producers. And the best the medical community can do is speculate at the real cause for a significant cancer? Perhaps prostate cancer is the real cause of global warming, there is no real science unless there is a real paycheck?
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.
Testosterone, historically believed to be important only for male sexual function, has over the past decades transformed from niche hormone to multi-system player.22 There is increasing recognition of the harmful consequences of hypogonadism (also known as testosterone deficiency) wide spectrum of beneficial health effects of testosterone therapy and.23, 24
In many of the studies we found, those who saw the most improvement in health, testosterone, or muscle gain were those with existing nutrient or vitamin deficiencies. This means that some gains may be due more to dietary changes and generally restoring nutrient and vitamin levels than any one magic ingredient, but also that making sure your diet includes healthy amounts of nutrients should be your first step.
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].
Thomas M. Gill, MD, Humana Foundation Professor of Medicine at Yale University School of Medicine in New Haven, CT, told EndocrineWeb that these trials were needed because “the pharmaceutical industry did a very good job of promoting testosterone, and there have been suggestions of parallels between age-related decreases in testosterone levels in men, and menopause in older women.”
Intramuscular testosterone injections were first used around fifty years ago. Commercially available preparations contain testosterone esters in an oily vehicle. Esterification is designed to retard the release of testosterone from the depot site into the blood because the half life of unmodified testosterone would be very short. For many years intramuscular preparations were the most commonly used testosterone therapy and this is still the case in some centers. Pain can occur at injection sites, but the injections are generally well tolerated and free of major side effects. Until recently, the available intramuscular injections were designed for use at a frequency of between weekly and once every four weeks. These preparations are the cheapest mode of testosterone treatment available, but often cause supraphysiological testosterone levels in the days immediately following injection and/or low trough levels prior to the next injection during which time the symptoms of hypogonadism may return (Nieschlag et al 1976). More recently, a commercial preparation of testosterone undecanoate for intramuscular injection has become available. This has a much longer half life and produces testosterone levels in the physiological range throughout each treatment cycle (Schubert et al 2004). The usual dose frequency is once every three months. This is much more convenient for patients but does not allow prompt cessation of treatment if a contraindication to testosterone develops. The most common example of this would be prostate cancer and it has therefore been suggested that shorter acting testosterone preparations should preferably used for treating older patients (Nieschlag et al 2005). Similar considerations apply to the use of subcutaneous implants which take the form of cylindrical pellets injected under the skin of the abdominal wall and steadily release testosterone to provide physiological testosterone levels for up to six months. Problems also include pellet extrusion and infection (Handelsman et al 1997).
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.

Testosterone fluctuates according to age and life circumstance, often plummeting at the onset of parenthood, and spiking (for some) during moments of triumph. Romantic relationships, too, can impact a person’s testosterone production; though the reasons are still not fully understood, entering a relationship tends to increase women’s testosterone levels, while decreasing men’s. Since males produce significantly more testosterone than females—about 20 times more each day—females can be more sensitive to these fluctuations. High levels of testosterone, particularly in men, have been correlated with a greater likelihood of getting divorced or engaging in extramarital affairs, though a causal link has not been established.

Preliminary research has shown that clomiphene citrate (Clomid), a drug generally prescribed to stimulate ovulation in women struggling with infertility, can foster the production of natural testosterone, termed endogenous testosterone, in men. In a recent prospective study, 36 hypogonadal men took a daily dose of clomiphene citrate for at least three months. Within four to six weeks, all of the men had heightened levels of testosterone; none reported any side effects during the year they were followed.


Gary Womble… Get out of here with your quackery nonsense. No one likes trolls that want to push diet and weight loss pills as a serious solution to low t and ED. Anyone who reads your comment will waste at least 20 seconds of their life. What’s worse, they might listen to you instead of getting real medical advice that might actually help with an issue that is devastating to their lifestyle. And btw, before you decide to respond to this with more quackery, testimonials or fake research, know that I am a pharmaceutical scientist and won’t fall for your bogus statements
Cross-sectional studies have found a positive association between serum testosterone and some measures of cognitive ability in men (Barrett-Connor, Goodman-Gruen et al 1999; Yaffe et al 2002). Longitudinal studies have found that free testosterone levels correlate positively with future cognitive abilities and reduced rate of cognitive decline (Moffat et al 2002) and that, compared with controls, testosterone levels are reduced in men with Alzheimer’s disease at least 10 years prior to diagnosis (Moffat et al 2004). Studies of the effects of induced androgen deficiency in patients with prostate cancer have shown that profoundly lowering testosterone leads to worsening cognitive functions (Almeida et al 2004; Salminen et al 2004) and increased levels of serum amyloid (Gandy et al 2001; Almeida et al 2004), which is central to the pathogenesis of Alzheimer’s disease (Parihar and Hemnani 2004). Furthermore, testosterone reduces amyloid-induced hippocampal neurotoxity in vitro (Pike 2001) as well as exhibiting other neuroprotective effects (Pouliot et al 1996). The epidemiological and experimental data propose a potential role of testosterone in protecting cognitive function and preventing Alzheimer’s disease.
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.

My biggest symptom was fatigue. Interestingly, I had and have no problem with erections at all. Granted, I wasn’t getting spontaneous erections like when I was a teenager and into my late 20’s, but that was a good thing as getting an erection whenever and having no way to relieve it can get annoying. Anyway, my biggest concern with low T was/is energy levels and loss of muscle mass.
How do you boost testosterone naturally? Testosterone is a male sex hormone. Low levels can cause changes to the distribution of body fat and muscle strength. Testosterone reduces with age, but people can boost it with lifestyle changes, including diet and exercise. Adequate sleep, nutritional supplements, and stress reduction may also help.

Although, most studies on TT have been conducted on animals, the results appear promising. One study that looked at sexually sluggish male albino rats found that having been given extracts of TT, the rats "mount frequency, intromission frequency, and penile erection index" all increased, while "mount latency, intromission latency, and ejaculatory latency" all decreased. Who said romance was dead?

A large number of trials have shown the positive effects of testosterone treatment on markers of bone formation and increased bone density in hypogonadal men treated with testosterone.1,4,6,8,13 Not surprisingly, the effects may take several years to fully develop. At present no data on the role of testosterone in preventing fracture in men with hypogonadism are available.

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.

“I'm 55 years old and hitting the ball further than I've ever hit, and I'm not getting tired going 18 holes! And when I play softball I'm hitting the ball further. I work for the DWP in LA and it's a very physically demanding job. Andro400 really helps because we work 16 hour days a lot. I was turning down a lot of overtime, but when I started taking Andro400, it got me through the day. I really notice a difference – even my wife did. It really works!”
Testosterone is observed in most vertebrates. Testosterone and the classical nuclear androgen receptor first appeared in gnathostomes (jawed vertebrates).[193] Agnathans (jawless vertebrates) such as lampreys do not produce testosterone but instead use androstenedione as a male sex hormone.[194] Fish make a slightly different form called 11-ketotestosterone.[195] Its counterpart in insects is ecdysone.[196] The presence of these ubiquitous steroids in a wide range of animals suggest that sex hormones have an ancient evolutionary history.[197]
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]

Stress less – I know this is easier said than done but if you can reduce your stress levels it will help your testosterone production. This is because stress makes your body produce cortisol which has many negative effects on the body including being a testosterone killer. Try meditating, exercising, deep breathing and other lifestyle changes to keep stress down and cortisol in check.
Workouts lasting longer than about an hour may begin to spike cortisol levels and subsequently decrease testosterone. Additionally, research has demonstrated that a shorter rest period between sets (1 minute versus 3 minutes) elicited higher acute hormonal responses following a bout of resistance training.11 To maximize your testosterone response, keep your rest periods short and total workout time to 60 minutes or fewer.

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.

We kept it simple, and followed the premise of testosterone boosters: testosterone affects muscle gain, weight loss, and libido, so by increasing the amount of testosterone in the body, we can improve on each of those goals. This meant that we looked for ingredients proven to increase testosterone levels, not ingredients that might increase libido or help build muscle mass independently of testosterone (like having a healthy diet and feeling good about yourself). In addition, we dove deep into the specific ingredient lists of our finalists and cross-checked them against WebMD and the National Institutes of Health (NIH) database to make sure that they did not contain ingredients known to be harmful.

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.

Zinc is an essential mineral that plays an important role in improving testosterone levels as well as sperm production. Oysters are rich sources of this mineral. An increase in testosterone levels also helps improve your sexual desire and energy, which means that you are going to derive more pleasure from your sexual encounters besides having higher chances of conceiving.

In addition to its role as a natural hormone, testosterone is used as a medication, for instance in the treatment of low testosterone levels in men and breast cancer in women.[10] Since testosterone levels decrease as men age, testosterone is sometimes used in older men to counteract this deficiency. It is also used illicitly to enhance physique and performance, for instance in athletes.
"A lot of the symptoms are mirrored by other medical problems," Hedges says. "And for a long time, we were not attributing them to low testosterone, but to diabetes, depression, high blood pressure, and coronary artery disease. But awareness and appreciation of low testosterone has risen. We recognize now that low testosterone may be at the root of problems."
