Phthalates are found to cause poor testosterone synthesis by disrupting an enzyme required to create the male hormone. Women with high levels of DEHP and DBP (two types of phthalates) in their system during pregnancy were found to have sons that had feminine characteristics Phthalates are found in vinyl flooring, detergents, automotive plastics, soaps and shampoos, deodorants, perfumes, hair sprays, plastic bags and food packaging, among a long list of common products. Aside from phthalates, other chemicals that possess gender-bending traits are:
The use of anabolic steroids (manufactured androgenic hormones) shuts down the release of luteinising hormone and follicle stimulating hormone secretion from the pituitary gland, which in turn decreases the amount of testosterone and sperm produced within the testes. In men, prolonged exposure to anabolic steroids results in infertility, a decreased sex drive, shrinking of the testes and breast development. Liver damage may result from its prolonged attempts to detoxify the anabolic steroids. Behavioural changes (such as increased irritability) may also be observed. Undesirable reactions also occur in women who take anabolic steroids regularly, as a high concentration of testosterone, either natural or manufactured, can cause masculinisation (virilisation) of women.

Your body’s circadian rhythm essentially resets itself every night and releases chemicals like cortisol, which contribute to the overall hormone balance that can prevent low T-levels. I have even heard one endocrinologist claim that one hour of sleep between 10 p.m. and 2 a.m. has the same healing effects on your body as two hours of sleep before or after this timeslot!

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.

A loophole in FDA regulations allows pharmaceutical marketers to urge men to talk to their doctors if they have certain "possible signs" of testosterone deficiency. "Virtually everybody asks about this now because the direct-to-consumer marketing is so aggressive," says Dr. Michael O'Leary, a urologist at Harvard-affiliated Brigham and Women's Hospital. "Tons of men who would never have asked me about it before started to do so when they saw ads that say 'Do you feel tired?'"


Watch out for ingredients that interfere with blood clotting If you are taking any kind of blood medication, take aspirin or ibuprofen, or have any kind of blood-related condition, you’ll want to consult your doctor before taking any of these supplements. Fenugreek, Forskolin, and Acetyl-L-carnitine are just a few of the ingredients that can make these situations worse and increase your chances of bruising and bleeding.
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][67][68][69] Studies have also found that testosterone facilitates aggression by modulating vasopressin receptors in the hypothalamus.[70]
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.
Sexual arousal - boosting testosterone can improve sexual arousal, even if you have normal testosterone levels. Higher levels of testosterone can make it easier for you to get aroused and can boost your sex drive generally. While this doesn’t affect the physical action of your erections, if you are not getting hard because you’re not aroused then boosting testosterone could help.
Every vitamin, mineral, and ingredient that affects the human body can be taken in enough quantities that they are harmful, or toxic, even the ones that — at lower levels — are beneficial or necessary. Unfortunately, testosterone boosters contain a lot of ingredients that are not well understood. This means in addition to not being able to confirm whether certain ingredients increase testosterone, the scientific and medical communities also don’t know at what levels many ingredients become toxic. On the up side, you might need to eat several pounds of a particular leafy plant before it becomes harmful. On the down side, it could be significantly less that pushes you over your body’s limit. We simply don’t know how little or how much the human body can tolerate. We recommend keeping your doctor in the loop when you add any supplement with unproven ingredients into your diet — they’ll be able to help you find and track any undesired side-effects that these ingredients might cause.

Here’s a scary thought: You may be less of a man than your father was—at least hormonally. A study in the Journal of Clinical Endocrinology and Metabolism found that, on average, testosterone levels were higher in men of the same age in the ’80s than they were in the 2000s (due, researchers speculate, to higher rates of obesity and the wider use of medication these days).  
Why niacinamide could positively impact 5-a reduced androgens? It’s complex, but simply put, its a crucial part of this compound called NADPH (Nicotinamide adenine dinucleotide phosphate). And NADPH is a co-factor in many anabolic/androgenic reactions of the body, including both testosterone and dihydrotestosterone production (NADPH is needed for the production of 5-ar enzyme).
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.

There is increasing interest in the group of patients who fail to respond to treatment with PDE-5 inhibitors and have low serum testosterone levels. Evidence from placebo-controlled trials in this group of men shows that testosterone treatment added to PDE-5 inhibitors improves erectile function compared to PDE-5 inhibitors alone (Aversa et al 2003; Shabsigh et al 2004).
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.
In summary, low testosterone levels are linked to the presence of numerous cardiovascular risk factors. Testosterone treatment acts to improve some of these factors, but effects may vary according to pre- and post-treatment testosterone levels, as well as other factors. There is little data from trials specific to aging males. Appropriately-powered randomized controlled trials, with cardiovascular disease primary endpoints, are needed to clarify the situation, but in the meantime the balance of evidence is that testosterone has either neutral or beneficial effects on the risk of cardiovascular disease in men. It is particularly important to define the effect of testosterone treatment on cardiovascular disease in view of its potential use as an anti-anginal agent.

The bones and the brain are two important tissues in humans where the primary effect of testosterone is by way of aromatization to estradiol. In the bones, estradiol accelerates ossification of cartilage into bone, leading to closure of the epiphyses and conclusion of growth. In the central nervous system, testosterone is aromatized to estradiol. Estradiol rather than testosterone serves as the most important feedback signal to the hypothalamus (especially affecting LH secretion).[115] In many mammals, prenatal or perinatal "masculinization" of the sexually dimorphic areas of the brain by estradiol derived from testosterone programs later male sexual behavior.[116]

A blood test is the only way to diagnose a low testosterone level or a reduction in the bioavailability of testosterone. Some men have a lower than normal testosterone level without signs or symptoms. For most men, no treatment is needed. But for some others, very low testosterone levels lead to a condition in which bones become weak and brittle (osteoporosis). For others, low testosterone might cause changes in sexual function, sleep patterns, emotions and the body.
In males, the testosterone test can help find the reason for sexual problems, like reduced sex drive or erectile dysfunction. If you’re having a hard time getting your partner pregnant, the test can tell if your blood testosterone level is low. It can also screen for problems with the hypothalamus or pituitary gland. This controls how much testosterone your body makes.
We required all of our testosterone boosters to have magnesium, but gave preference to magnesium aspartate, citrate, lactate, and chloride. These forms have been found to be more easily absorbed than magnesium oxide and sulfate. (On the other hand, it didn’t count if the supplement had magnesium stearate, which is used to make pills not stick together.)
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.
Drumstick vegetable or Moringa oleifera is known for being 'libido-booster' in India. Whenever a guy buys a bunch of drumsticks in the market, people usually stare at him with the face 'he's planning a party tonight!' Although many studies are needed to prove it, Moringa is a rich source of magnesium, calcium and vitamin c. Moringa can also be considered a decent source of anti-oxidants.

Decreased testosterone production in men with rheumatoid arthritis is a common finding (Stafford et al 2000), and it is now generally recognized that androgens have the capacity to suppress both the hormonal and cellular immune response and so act as one of the body’s natural anti-inflammatory agents (Cutolo et al 2002). This known anti-inflammatory action of testosterone has led to studying the effect of testosterone therapy in men with rheumatoid disease. Although not all studies have reported positive effects of testosterone treatment (Hall et al 1996), some studies do demonstrate an improvement in both clinical and chemical markers of the immune response (Cutolo et al 1991; Cutolo 2000). This observation would go along with more recent evidence that testosterone or its metabolites protects immunity by preserving the number of regulatory T cells and the activation of CD8+ T cells (Page et al 2006).
The illegal testosterone supplements give immediate results and can be obtained without a prescription. However, it is strongly recommended to avoid these boosters as they contain an anabolic steroid, which is harmful to the body. The legal kinds of them are the best testosterone supplements and are considered as safe and efficient for muscle growth and to increase sex drive, but they are also not completely devoid of adverse effects. There are many side effects associated with the use of these testosterone therapy. The natural testosterone boosters are the safest and highly recommended testosterone supplements.
"I am only 10 weeks into taking your product and I have lost 12 pounds and three inches from my waist. Normally I scoff at radio or TV ads promising results like this. But in this case, my results have far exceeded my expectations. My energy level has increased and my appetite has decreased! All this without any extra exercise program. Thanks from a very satisfied customer!"
Looking for ingredients that work in the realm of supplements can be like finding a needle in a haystack. Testosterone boosters, like all dietary supplements, are not approved by the Food and Drug Administration prior to marketing. This lack of oversight dates back to the 1994 Dietary Supplement Health and Education Act (DSHEA), which stipulated that purveyors of supplements weren’t required to prove the safety of their products or the veracity of what’s on the labels to the FDA before listing them for sale. Often, there isn’t a lot of scientific backing behind an ingredient, or research has been done solely on animals, not humans.
Pine Pollen is an androgen, meaning in theory it can raise testosterone levels – effectively making it a naturally derived source of testosterone. Read more about this on the links below. But like I said I started taking it for a few weeks and did notice a bit more ‘up and go’ so to speak, but it did only last a few weeks. I have tried cycling it but haven’t noticed the same effects as I had when I initially started with it. I’m still experimenting and will keep this page updated. Therefore I recommend doing your own research.
For example, the study published in Obesity Research tells that the scientists measured testosterone levels in two groups of middle-aged men with obesity. One group underwent a 16-week weight loss program, while the second group did nothing. Each participant of the first group lost 20 kg on the average. And these participants experienced a significant increase in testosterone levels. So, the fight against overweight is very important for those who want to overcome testosterone deficiency. But starvation is strictly forbidden because this is a stressful situation which leads to the sharp decline in T levels.
Recent reports have revealed that there may be an unaired episode of the hit series Shark Tank in which a new testosterone supplement landed the biggest deal in the show's history! Supposedly, two sisters from Korea, Angela and Yoojin Kim, had created an innovative supplement that promotes muscle growth and resolves erectile dysfunction! Inside sources say that when they presented their product to the Sharks, it got an overwhelming response!
Pregnant or nursing women who are exposed to EDCs can transfer these chemicals to their child. Exposure to EDCs during pregnancy affects the development of male fetuses. Fewer boys have been born in the United States and Japan in the last three decades. The more women are exposed to these hormone-disrupting substances, the greater the chance that their sons will have smaller genitals and incomplete testicular descent, leading to poor reproductive health in the long term. EDCs are also a threat to male fertility, as they contribute to testicular cancer and lower sperm count. All of these birth defects and abnormalities, collectively referred to as Testicular Dysgenesis Syndrome (TDS), are linked to the impaired production of testosterone.5
Ten healthy men aged around 24 years old spent 1 week sleeping for 8 hours per night at home, they then spent the next 11 nights in a lab. They slept for 10 hours per night for 3 nights, followed by 8 nights of restricted sleep, when they slept for only 5 hours. Doctors checked their blood every 15 to 30 minutes during the last night that they slept 10 hours, as well as on the sleep-restricted session.
Another effect that can limit treatment is polycythemia, which occurs due to various stimulatory effects of testosterone on erythropoiesis (Zitzmann and Nieschlag 2004). Polycythemia is known to produce increased rates of cerebral ischemia and there have been reports of stroke during testosterone induced polycythaemia (Krauss et al 1991). It is necessary to monitor hematocrit during testosterone treatment, and hematocrit greater than 50% should prompt either a reduction of dose if testosterone levels are high or high-normal, or cessation of treatment if levels are low-normal. On the other hand, late onset hypogonadism frequently results in anemia which will then normalize during physiological testosterone replacement.
Lose some weight – It goes without saying that being overweight is unhealthy for more than one reason. As your weight increases, your testosterone levels decrease inevitably. The good news is that as soon as you start losing weight, you can reverse this process and your testosterone levels will begin rising again. Could you think of a better reason to exercise regularly?

One study looking at alcohol consumption found that increasing alcohol consumption led to a higher level of free & total testosterone compared to a non-drinking control group (20). Drinking did however lower SHBG testosterone levels, though this type of testosterone is bound to a protein meaning our bodies cannot use it to build muscle or increase our mood.
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).

A diagnosis of low testosterone is typically made if a man’s free testosterone hormone level is below 300 ng/dL. But as a doctor specializing in sexual health, I typically consider optimized male testosterone levels somewhere between 600 to 800 ng/dL—rarely above or below those numbers. The tests that I routinely recommend to my male clients can be found in this test panel and include biomarkers associated with testosterone, free and total (this includes sex-hormone binding globulin [SHBG]), estradiol, estrogen (total and serum), cortisol, DHEAs, thyroid-stimulating hormone (TSH), hemoglobin A1C, and vitamin D.

A: Testosterone products can improve a male's muscle strength and create a more lean body mass. Typically, these effects are not noticed within the first two weeks of therapy, but it is possible that he is more sensitive and responds well to the therapy. Some of the other more common side effects of testosterone patches are headache, depression, rash, changes in libido, acne, male pattern baldness, and increased cholesterol levels. This is not a complete list of the side effects associated with testosterone patches. Megan Uehara, PharmD
Take 1 teaspoon. Incredibly dense in nutrients and feed by bees to the larvae who grows on to be the queen bee. I found one human study where a 4g daily serving led to an small increase in testosterone in older men (ref 78). There are also numerous animal studies (ref 79) showing positive effects. Personally I source NZ manuka royal jelly from Manuka Health.
Many clinical studies have looked at the effect of testosterone treatment on body composition in hypogonadal men or men with borderline low testosterone levels. Some of these studies specifically examine these changes in older men (Tenover 1992; Morley et al 1993; Urban et al 1995; Sih et al 1997; Snyder et al 1999; Kenny et al 2001; Ferrando et al 2002; Steidle et al 2003; Page et al 2005). The data from studies, on patients from all age groups, are consistent in showing an increase in fat free mass and decrease in fat mass or visceral adiposity with testosterone treatment. A recent meta-analysis of 16 randomized controlled trials of testosterone treatment effects on body composition confirms this pattern (Isidori et al 2005). There have been less consistent results with regard to the effects of testosterone treatment of muscle strength. Some studies have shown an increase in muscle strength (Ferrando et al 2002; Page et al 2005) with testosterone whilst others have not (Snyder et al 1999). Within the same trial some muscle group strengths may improve whilst others do not (Ly et al 2001). It is likely that the differences are partly due to the methodological variations in assessing strength, but it also possible that testosterone has different effects on the various muscle groups. The meta-analysis found trends toward significant improvements in dominant knee and hand grip strength only (Isidori et al 2005).
Having low T is associated with decreased sex drive and less muscle mass, and one new study even found that lower levels of testosterone may raise the risk of depression. Fortunately, strength training spikes T, and living a healthy lifestyle also goes a long way toward keeping your levels topped off. But there are some completely natural compounds that can help as well.
Supplement nutrients when levels are low. Low levels of zinc and vitamin D may contribute to low testosterone levels in teenage boys, so increasing these nutrients through diet or dietary supplements can also help boost your testosterone. If your zinc and/or vitamin D levels are already normal, though, use caution before further increasing those levels with supplements.
Spinach/Spring Salad Mix. This was the base of my salad. I used Organic Girl Greens from Whole Foods. Yeah, I know. The base of my Man Salad came from a company called Organic Girl. Spinach and other leafy green vegetables contain minerals like magnesium and zinc, which have been shown to aid in testosterone production (study on magnesium, and another; study on zinc)

The regulation of testosterone production is tightly controlled to maintain normal levels in blood, although levels are usually highest in the morning and fall after that. The hypothalamus and the pituitary gland are important in controlling the amount of testosterone produced by the testes. In response to gonadotrophin-releasing hormone from the hypothalamus, the pituitary gland produces luteinising hormone which travels in the bloodstream to the gonads and stimulates the production and release of testosterone.
