While it would be nice to buy a testosterone pill from the local supplement store and have your testosterone levels go up, such a magic pill does not exist. As you can see from the above rundown, while a few supplements may be somewhat effective if your T levels are already low, none will significantly raise your testosterone above a baseline level. Thus, the basics of keeping your T levels high remain pretty simple:
As you can see, the entire workout is only 20 minutes. Twenty minutes! That really is a beautiful thing. And within those 20 minutes, 75 percent of that time is warming up, recovering or cooling down. You're really only working out intensely for four minutes. It's hard to believe if you have never done this that you can actually get that much benefit from four minutes of exercise. That's all it is.

In addition to conjugation and the 17-ketosteroid pathway, testosterone can also be hydroxylated and oxidized in the liver by cytochrome P450 enzymes, including CYP3A4, CYP3A5, CYP2C9, CYP2C19, and CYP2D6.[155] 6β-Hydroxylation and to a lesser extent 16β-hydroxylation are the major transformations.[155] The 6β-hydroxylation of testosterone is catalyzed mainly by CYP3A4 and to a lesser extent CYP3A5 and is responsible for 75 to 80% of cytochrome P450-mediated testosterone metabolism.[155] In addition to 6β- and 16β-hydroxytestosterone, 1β-, 2α/β-, 11β-, and 15β-hydroxytestosterone are also formed as minor metabolites.[155][156] Certain cytochrome P450 enzymes such as CYP2C9 and CYP2C19 can also oxidize testosterone at the C17 position to form androstenedione.[155]

Prolactin is suppressed by dopamine activity. Since supplementing L-DOPA suppresses prolactin (by increasing dopamine activity), supplementing L-DOPA would increase testosterone if prolactin was abnormally high. The average, healthy male does not have elevated prolactin (unless he’s on steroids), so supplementing with L-DOPA will not increase your testosterone levels.
The maximum hormone concentration in the blood is reported immediately after the workout. And the effect lasts throughout the day. However, it’s important to ensure that your physical activity is moderate. The matter is that too much high-intensity exercise can give an undesirable result. But even if for any reason you can’t attend a gym, it’s not a problem. Just move as much as possible during the day. Even simple walking will be of great benefit.
Attention, memory, and spatial ability are key cognitive functions affected by testosterone in humans. Preliminary evidence suggests that low testosterone levels may be a risk factor for cognitive decline and possibly for dementia of the Alzheimer's type,[100][101][102][103] a key argument in life extension medicine for the use of testosterone in anti-aging therapies. Much of the literature, however, suggests a curvilinear or even quadratic relationship between spatial performance and circulating testosterone,[104] where both hypo- and hypersecretion (deficient- and excessive-secretion) of circulating androgens have negative effects on cognition.
There is a polymorphic CAG repeat sequence in the androgen receptor gene, which codes for a variable number of glutamine amino acids in the part of the receptor affecting gene transcription. A receptor with a short CAG sequence produces greater activity when androgens attach, and men with shorter CAG polymorphisms exhibit androgenic traits, such as preserved bone density (Zitzmann et al 2001) and prostate growth during testosterone treatment (Zitzmann et al 2003). Indirect evidence of the importance of androgens in the development of prostate cancer is provided by case control study findings of a shorter, more active CAG repeat sequence in the androgen receptor gene of patients with prostate cancer compared with controls (Hsing et al 2000, 2002).

A recent study conducted on trained subjects showed that squats stimulated a greater testosterone response than leg presses.10 Stick with multijoint exercises like squats, bench presses, and deadlifts—the kinds of compound lifts that'll help jack up your testosterone levels. Since machines isolate a muscle you're working (less stabilizer activity), they're not as good a choice compared to free weights.

Keep more weapons in your arsenal: Occasionally use lifting methods like forced reps, negatives, and dropsets to further stress your body. Personal trainer and fitness journalist Michael Berg explains in "6 Ways to Crank Up Your Testosterone Levels" that going beyond muscular failure with these techniques has been shown to pump up T-levels in study subjects.[16]
Testosterone boosters are a class of herbal supplements aimed at naturally increasing your testosterone levels. Usually, they contain micronutrients that men are commonly deficient in, such as zinc, and which have been connected in research to healthy testosterone levels. They also may contain adaptogens, which are a class of supplement that are thought to help the body adapt to stress, or ingredients which have been connected to improved sleep. Sleep restriction has been shown to reduce testosterone in healthy young men, and as Chris Lockwood, Ph.D., notes, disturbed sleep is a common symptom of low T-levels.[1]
12)  Use Aswaghanda and Collagen Protein:  This adaptogenic herb has been shown to reduce stress hormone, increase DHEA and boost testosterone levels.  You can take the Cortisol Defense to help you get restorative sleep at night which will support your testosterone.  In addition, I personally enjoy using the Organic Bone Broth Collagen in addition to the Amino Strong for a post weight training shake.  This protein powder has all the benefits of collagen protein and it has 500 mg of high potency ashwagandha in each serving!

A number of epidemiological studies have found that bone mineral density in the aging male population is positively associated with endogenous androgen levels (Murphy et al 1993; Ongphiphadhanakul et al 1995; Rucker et al 2004). Testosterone levels in young men have been shown to correlate with bone size, indicating a role in determination of peak bone mass and protection from future osteoporosis (Lorentzon et al 2005). Male hypogonadism has been shown to be a risk factor for hip fracture (Jackson et al 1992) and a recent study showed a high prevalence of hypogonadism in a group of male patients with average age 75 years presenting with minimal trauma fractures compared to stroke victims who acted as controls (Leifke et al 2005). Estrogen is a well known determinant of bone density in women and some investigators have found serum estrogen to be a strong determinant of male bone density (Khosla et al 1998; Khosla et al 2001). Serum estrogen was also found to correlate better than testosterone with peak bone mass (Khosla et al 2001) but this is in contradiction of a more recent study showing a negative correlation of estrogen with peak bone size (Lorentzon et al 2005). Men with aromatase deficiency (Carani et al 1997) or defunctioning estrogen receptor mutations (Smith et al 1994) have been found to have abnormally low bone density despite normal or high testosterone levels which further emphasizes the important influence of estrogen on male bone density.
And remember, saturated fats work best (along with monounsaturated fats – olive oil, almonds, avocados etc.). In fact higher intakes of polyunsaturated fats (canola oil, sunflower oil, soybean oil, safflower oil, margarine etc.) are linked to LOWER testosterone levels (14 & 15). I explore the dangers of PUFA's in a lot more detail in this article - PUFA's: The Worst Thing For Your Health That You Eat Everyday.
At the National Population and Family Development Board in Malaysia, men between the ages of 31 and 52 were given two capsules of the herb (E. longifolia) in Andro400 every day for three weeks. They reported erections were stronger and, in some cases, lasted longer. Overall, they felt more virile. Their levels of testosterone doubled within three weeks.5
The yolks of eggs exclusively are a fine source of Zinc. Egg yolks have all of the vitamins that are present in the whole egg as well. So, by consuming the yolk itself, you would get more than required fat, but you also get vitamins A, E, D and K, as well as additional amounts of minerals. Zinc and vitamin D - the pro-testosterone duo are in the captain seat in egg yolks.
When you're under a lot of stress, your body releases high levels of the stress hormone cortisol. This hormone actually blocks the effects of testosterone,6 presumably because, from a biological standpoint, testosterone-associated behaviors (mating, competing, aggression) may have lowered your chances of survival in an emergency (hence, the "fight or flight" response is dominant, courtesy of cortisol).
Among the changes which occur with aging are those that affect several aspects of the endocrine system which reduces its secretions to varying degrees in different individuals. These reductions in secretions are identified by a poor but widely recognized appellation, the “pauses”: menopause (decreased ovarian function), adrenopause (decreased adrenal function, especially with regard to dehydroepiandrosterone secretion), somatopause (decreased growth hormone production), andropause (decreased hypothalamic-pituitary testicular function with diminished testosterone availability and impaired spermatogenesis) (Lamberts 1997).

However, testosterone is only one of many factors that aid in adequate erections. Research is inconclusive regarding the role of testosterone replacement in the treatment of erectile dysfunction. In a review of studies that looked at the benefit of testosterone in men with erection difficulties, showed no improvement with testosterone treatment. Many times, other health problems play a role in erectile difficulties. These can include:
Some of these signs and symptoms can be caused by various underlying factors, including medication side effects, obstructive sleep apnea, thyroid problems, diabetes and depression. It's also possible that these conditions may be the cause of low testosterone levels, and treatment of these problems may cause testosterone levels to rise. A blood test is the only way to diagnose a low testosterone level.
