In the hepatic 17-ketosteroid pathway of testosterone metabolism, testosterone is converted in the liver by 5α-reductase and 5β-reductase into 5α-DHT and the inactive 5β-DHT, respectively.[1][151] Then, 5α-DHT and 5β-DHT are converted by 3α-HSD into 3α-androstanediol and 3α-etiocholanediol, respectively.[1][151] Subsequently, 3α-androstanediol and 3α-etiocholanediol are converted by 17β-HSD into androsterone and etiocholanolone, which is followed by their conjugation and excretion.[1][151] 3β-Androstanediol and 3β-etiocholanediol can also be formed in this pathway when 5α-DHT and 5β-DHT are acted upon by 3β-HSD instead of 3α-HSD, respectively, and they can then be transformed into epiandrosterone and epietiocholanolone, respectively.[153][154] A small portion of approximately 3% of testosterone is reversibly converted in the liver into androstenedione by 17β-HSD.[152]
Osteoporosis refers to pathological loss of bone density and strength. It is an important condition due to its prevalence and association with bone fractures; most commonly of the hip, vertebra and forearm. Men are relatively protected from the development of osteoporosis by a higher peak bone mass compared with women (Campion and Maricic 2003). Furthermore, women lose bone at an accelerated rate immediately following the menopause. Nevertheless, men start to lose bone mass during early adult life and experience an increase in the rate of bone loss with age (Scopacasa et al 2002). Women of a given age have a higher prevalence of osteoporosis in comparison to men but the prevalence increases with age in both sexes. As a result, men have a lower incidence of osteoporotic fractures than women of a given age but the gap between the sexes narrows with advancing age (Chang et al 2004) and there is evidence that hip fractures in men are associated with greater mortality than in women (Campion and Maricic 2003).

Magnesium comes with a strict upper cap. Excess magnesium is hard on your kidneys, and can lead to kidney failure. The NIH recommends that men consume 400-420 mg of magnesium daily, but that they should not exceed 350 mg of supplemental magnesium per day. Because while it’s rare for people to chronically overdose on magnesium through diet (you’d have to eat a lot of almonds and spinach, for example), overdose by supplement is far more common.
Men who watch a sexually explicit movie have an average increase of 35% in testosterone, peaking at 60–90 minutes after the end of the film, but no increase is seen in men who watch sexually neutral films.[43] Men who watch sexually explicit films also report increased motivation, competitiveness, and decreased exhaustion.[44] A link has also been found between relaxation following sexual arousal and testosterone levels.[45]
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.

Reordering. My husband has been very tired (lazy), but unable to sleep, and quickly started gaining a belly. I give him his vitamins so he never knows what he is taking. Only 3 days after taking this, he played an entire soccer game and commented on how much more energy he had and how he just feels better all around. I then told him what he was taking. He has continued taking and he is like his old self again. His energy has not only come back on the soccer field, but in other areas, as well.
If you still feel the need to supplement, keep in mind that supplemental magnesium is more likely than dietary magnesium to cause adverse effects, which is why the FDA fixed at 350 mg the Tolerable Upper Intake Level for magnesium supplementation in adults. Also, you may want to avoid magnesium oxide: it has poor bioavailability (rats absorbed only 15% in one study,[43] and humans only 4% in another[44]) and can cause intestinal discomfort and diarrhea.
There are supplements out there that promise to increase your libido while also upping your testosterone. There are over the counter testosterone supplements and prescription supplements. There are supplements that market themselves as T-boosters, while also touting themselves as an aphrodisiac. And then there are companies that claim to have developed a testosterone pill that contains the triumvirate of male-enhancing properties: T-boosting, libido-enhancing, and even fertility-increasing. These supplement makers sometimes throw in an additional claim of muscle gain as well.
Heavy metal, fluoride, chlorine, pesticides, dioxins and other dangerous chemicals that are in our food, products and even the air we breath are wreaking absolute havoc on our endocrine systems (responsible for testosterone production). It’s hard to avoid these (especially if you’re a smoker) but they are major contributors to man’s decline in testosterone.
The same study showed that drinking did, however, lower semen count and quality. And I want to remind you – this is an article  on improving testosterone levels, not general health as there are a lot of studies that show drinking leads to an assortment of health issues. This acute spike in Testosterone could be due to the effect alcohol has on libido, and also the energy influx in the liver?

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).
Most Americans today are sleep deprived, which may be a contributing factor to declining testosterone levels in men. See, our body makes nearly all the testosterone it needs for the day while we’re sleeping. That increased level of T that we experience at night is one of the reasons we wake up with “Morning Wood.” (If you don’t have Morning Wood on a consistent basis, you might have low T).
If you are serious about losing weight, you have got to strictly limit the amount of processed sugar in your diet, as evidence is mounting that excess sugar, and fructose in particular, is the primary driving factor in the obesity epidemic. So cutting soda from your diet is essential, as is limiting fructose found in processed foods, fruit juice, excessive fruit and so-called "healthy" sweeteners like agave.

In summary it’s important to know that this topic is still hotly debated, and there are a lot of inconsistencies in the data. We do know that soy contains phytoestrogens and does seem to have a lot of affects on the body, including some studies that show decreased Testosterone levels. For that reason (and the fact that it tastes like ass) I avoid it, and I recommend you also avoid it (in particular soy isolates!) if you’re seeking higher testosterone.

The confusion is understandable, as one in-vitro study noted that high doses of zinc blocked the enzyme 5-a reductase inside test-tubes. But the studies that don’t see much daylight actually show that oral zinc supplementation on actual living, breathing, humans is able to significantly boost the production of dihydrotestosterone, and it does so even when there’s no deficiency in the mineral.
​You might know all about testosterone and its functions. Otherwise, you wouldn't have stumbled upon this article. You can't consider yourself a man if you have no idea what testosterone is. Obviously, it's the male sex hormone. But for those who are wondering what a decent amount of testosterone could do, here are some of the great stuff it is vital for-
We do note that Beast Sports’ supplemental magnesium level is fairly low — 26 mg per serving, up to 52 mg per day. If your diet is not particularly rich in magnesium (found in leafy greens, nuts, and whole grains), Beast Sports may not give you enough to meet the daily recommended dose. However, if you’re taking other multi-vitamins or supplements with magnesium, you’re less likely to cross that 350mg daily upper limit.
