Sleep apnea is another frequently listed contraindication to testosterone treatment. There have been a few reports of the development, or worsening, of sleep apnea during testosterone therapy (Matsumoto et al 1985) but sleep apnea is actually associated with lower serum testosterone levels (Luboshitzky et al 2002). The reduction in fat mass during treatment with testosterone could potentially be beneficial for sleep apnea, so many specialists will still consider patients for treatment with appropriate monitoring. It is wise to take a clinical history for sleep apnea during testosterone treatment in all men and perform sleep studies in those who develop symptoms.
The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression".[78][79] Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible.[78] The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game.[80] Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males.[81][82][83][84][85]
Testosterone is everywhere playing multiple roles from intrauterine life to advanced age. Table 1, the contents of which are always undergoing change primarily because of newly observed associations, provides an overview of the bodily systemic functions and patho-physiological states in which testosterone finds itself implicated. In some of these states there is a clear physiological cause and effect relationship. In others, evidence of the physiological role is early or tenuous.
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: According to the NIH, normal values for testosterone levels in men can range from 300 to 1,200ng/dL. There can be many different causes of low testosterone including age, diseases, accidents, and medications. Symptoms of low testosterone may include: loss of sex drive, erectile dysfunction, depressed mood, and difficulty concentrating. Low testosterone levels may also bring around body changes including: hair loss, decrease in blood cells possibly leading to anemia, fragile bones, and a decrease in muscle mass. There are different testosterone replacement therapies including patches, such as Androderm; gels, such as Androgel and Testim; and injections, such as testosterone cypionate. Only your health care provider can decide if and what kind of testosterone replacement therapy is appropriate for you. Testosterone replacement therapy is not right for everyone. Patient with certain prostate issues or breast cancer should not take testosterone. For more specific information, consult with your doctor for guidance based on your health status and current medications, particularly before taking any action. Kristen Dore, PharmD
These results have been echoed in clinical trials. A meta-analysis of 24 RCTs looked at weight loss caused by diet or bariatric surgery:[22] In the diet studies, the average 9.8% weight loss was linked to a testosterone increase of 2.9 nmol/L (84 ng/dL). In the bariatric-surgery studies, the average 32% weight loss was linked to a testosterone increase of 8.7 nmol/L (251 ng/dL).

According to the Mayo Clinic, testosterone therapy can help treat hypogonadism. This condition occurs when the body can’t produce enough testosterone on its own. However, it’s unclear whether supplements can help. A study published in Nature Reviews Endocrinology found no scientific reason to prescribe testosterone to men over 65 years of age with normal or low to normal testosterone levels.
There is an increased incidence of hypogonadism in men with rheumatoid arthritis. Tengstrand et al (2002) studied hormonal levels in 104 men with rheumatoid arthritis and 99 age-matched healthy men. They divided their subjects into 3 age groups: 30–49, 40–59, 60–69. Mean non-sex hormone binding globulin-bound testosterone (bioavailable testosterone) was lower in men with rheumatoid arthritis for each of the three groups. LH was also found to be lower in the patients with rheumatoid arthritis suggesting a hypothalamic-pituitary cause of the reduced bioavailable testosterone. Of the 104 men with rheumatoid arthritis, 33 had hypogonadism compared to 7 of the 99 healthy controls.
Ashwagandha is shown to be effective at reducing cortisol which in turn helps with testosterone production. There are also numerous studies showing the effects on improving testosterone in infertile men (ref 80).  If you are using the Aggressive Strength product you don't need to supplement with ashwagandha as it's included in the test booster formula. Likewise if you're using Tian Chi (my daily herb drink).
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.
Consume organic dairy products, like high-quality cheeses and whey protein, to boost your branch chain amino acids (BCAA). According to research, BCAAs were found to raise testosterone levels, particularly when taken with strength training.12 While there are supplements that provide BCAAs, I believe that leucine, found in dairy products, carries the highest concentrations of this beneficial amino acid.
A: Depo-Testosterone is a brand name medication that contains testosterone cypionate. Depo-Testosterone is given as an intramuscular injection. The medication is indicated for replacement therapy for men that have conditions associated with symptoms of deficiency in the hormone or absence of testosterone produced in the body. Conditions that can be associated with low testosterone include: delayed puberty, impotence and hormonal imbalances. Testosterone is a sex hormone that is naturally produced in the male testicles. In women, small amounts of testosterone is produced in the ovaries and by the adrenal system. Testosterone is available in various medications for testosterone replacement therapy. Different forms of testosterone (e.g. cypionate, enanthate etc) are contained in different brand name medications. Jen Marsico, RPh
Testosterone is used as a medication for the treatment of males with too little or no natural testosterone production, certain forms of breast cancer,[10] and gender dysphoria in transgender men. This is known as hormone replacement therapy (HRT) or testosterone replacement therapy (TRT), which maintains serum testosterone levels in the normal range. Decline of testosterone production with age has led to interest in androgen replacement therapy.[105] It is unclear if the use of testosterone for low levels due to aging is beneficial or harmful.[106]
Why do we need magnesium? Magnesium is an essential nutrient in the body that can help decrease the risk of developing osteoporosis, improve insulin sensitivity, and lower the risk of hypertension. This article looks at other health benefits of magnesium, what happens if a person has a deficiency, supplements, and how to include it in the diet. Read now

Smoking doesn’t promote maintaining male hormone levels healthy. The study has shown that smoking deprives the body from zinc. Zinc deficiency is dangerous for men because it is fraught with testosterone deficiency. The matter is that zinc is a kind of structural material for building the testosterone molecules. So, smoking combined with unhealthy diet strikes a blow against normal testosterone production.
The testosterone booster pills are effective from 4 to 8 hours. To maintain testosterone levels high during the whole day, you need a multiple daily dosing regimen. 2-times daily dosing still not always can improve hormone production to the greatest extent. 3-4-times daily dosing is the best solution to make your body normalize testosterone synthesis and prevent it from decreasing before you take another pill. Don’t forget that the regularity of daily supplement intake is crucial if you really aspire to give a boost to hormone production.
The biggest change I made to my diet was increasing my fat and cholesterol intake. There’s a reason why old school strong men would drink raw eggs — studies have suggested that higher fat and cholesterol consumption results in increased levels of total T; men eating low-fat diets typically have decreased testosterone levels. The emphasis on increasing fat and cholesterol consumption meant I got to eat like Ron Swanson for three months — bacon and eggs and steak was pretty much the staple of my diet.
On review of the patient’s history, he was found to have undergone laboratory tests before starting to use the aforementioned testosterone booster product. All blood parameters (testosterone hormone and full chemical profile) before product intake were in the normal range. A physical examination that included blood pressure and pulse assessments showed nothing out of the ordinary, and the man appeared to be in good condition before product consumption. After that medical checkup, the athlete began to consume the product for 42 continuous days divided into 2 cycles (each cycle comprised 24 days). The daily dose was a single pack of Universal Nutrition Animal Stak (ingredients are listed in Table 1), following the exact direction of the manufacturing company hoping to get the best results.

Zinc is involved in virtually every aspect of male reproduction, including testosterone metabolism. Several studies support the use of zinc for treating low sperm counts, especially when accompanied by low testosterone levels. In these studies, zinc has shown an ability to raise both sperm counts and testosterone levels. Many men may be suffering from low testosterone simply because of a zinc deficiency. Taking 30–45 mg of zinc per day is recommended; balance with 2–3 mg of copper for best results.


Cross-sectional studies conducted at the time of diagnosis of BPH have failed to show consistent differences in testosterone levels between patients and controls. A prospective study also failed to demonstrate a correlation between testosterone and the development of BPH (Gann et al 1995). Clinical trials have shown that testosterone treatment of hypogonadal men does cause growth of the prostate, but only to the size seen in normal men, and also causes a small increase in prostate specific antigen (PSA) within the normal range (Rhoden and Morgentaler 2005). Despite growth of the prostate a number of studies have failed to detect any adverse effects on symptoms of urinary obstruction or physiological measurements such as flow rates and residual volumes (Snyder et al 1999; Kenny et al 2000, 2001). Despite the lack of evidence linking symptoms of BPH to testosterone treatment, it remains important to monitor for any new or deteriorating problems when commencing patients on testosterone treatment, as the small growth of prostate tissue may adversely affect a certain subset of individuals.


It seems that adequate testosterone levels are an important influence on sexual symptoms in the aging male and also influence the response of men to PDE-5 inhibitors, the first line treatment for erectile dysfunction in men. Many would now suggest screening for testosterone deficiency in all men presenting with erectile dysfunction (Gore and Rajfer 2004; Shabsigh 2005). This would seem appropriate because, in addition to benefits on sexual function, identification and treatment of hypogonadal men with testosterone could improve other symptoms of hypogonadism and protect against other conditions such as osteoporosis.

The Organon group in the Netherlands were the first to isolate the hormone, identified in a May 1935 paper "On Crystalline Male Hormone from Testicles (Testosterone)".[180] They named the hormone testosterone, from the stems of testicle and sterol, and the suffix of ketone. The structure was worked out by Schering's Adolf Butenandt, at the Chemisches Institut of Technical University in Gdańsk.[181][182]
Testosterone is a stimulant of hematopoiesis in the bone marrow and consequently, increases the hematocrit (Shahidi 1973). Men with unexplained anemia should have their testosterone measured and if reduced, these men should be treated with testosterone. Because of the erythropoietin stimulating effect of testosterone, one of the parameters to be monitored during testosterone treatment is hematocrit since a small percent of testosterone-treated men develop polycythemia.
Instead of turning to some drug that can only ameliorate symptoms and cause additional complications, I recommend using a natural saw palmetto supplement. Dr. Moerck says that there are about 100 clinical studies on the benefits of saw palmetto, one of them being a contributed to decreased prostate cancer risk. When choosing a saw palmetto supplement, you should be wary of the brand, as there are those that use an inactive form of the plant.

Dr. Anthony’s Notes: Correcting a common zinc deficiency can really help testosterone levels. This is why many supplement companies make testosterone boosting supplement stacks called “ZMA” (which stands for Zinc-Magnesium Aspartate) – which is essentially a combination of zinc and magnesium. Do note that LONG TERM high dose zinc supplementation is NOT a good idea (above 30-40mg). Taking too much zinc can lead to a copper deficiency (the two minerals compete for absorption), which causes problems of its own. Verdict: this is one of the natural testosterone supplements that work. Best Food Sources: Beef, lamb, oysters, pumpkin seeds, cashews, quinoa, turkey, chickpeas How To Take Zinc: 30mg once per day with food is ideal. And as we alluded to above in my “notes,” it's often best to take zinc WITH the next supplement on our list…

Transdermal preparations of testosterone utilize the fact that the skin readily absorbs steroid hormones. Initial transdermal preparations took the form of scrotal patches with testosterone loaded on to a membranous patch. Absorption from the scrotal skin was particularly good and physiological levels of testosterone with diurnal variation were reliably attained. The scrotal patches are now rarely used because they require regular shaving or clipping of scrotal hair and because they produce rather high levels of dihydrotestosterone compared to testosterone (Behre et al 1999). Subsequently, non-scrotal patches were developed but the absorptive capacity of non-scrotal skin is much lower, so these patches contain additional chemicals which enhance absorption. The non-scrotal skin patches produce physiological testosterone levels without supraphysiological dihydrotestosterone levels. Unfortunately, the patches produce a high rate of local skin reactions often leading to discontinuation (Parker and Armitage 1999). In the last few years, transdermal testosterone gel preparations have become available. These require daily application by patients and produce steady state physiological testosterone levels within a few days in most patients (Swerdloff et al 2000; Steidle et al 2003). The advantages compared with testosterone patches include invisibility, reduced skin irritation and the ability to adjust dosage, but concerns about transfer to women and children on close skin contact necessitate showering after application or coverage with clothes.

Finally, we looked at the proprietary blends of our remaining boosters, and dug into their ingredient lists. Supplements frequently include ingredients known for their “folk-lore” value; they’re believed to work, even when there isn’t any scientific background to prove it. Though we didn’t ding points if an ingredient wasn’t proven to be good (just so long as it wasn’t proven to be bad), we didn’t want to include any ingredient with evidence of causing harm.

Exercise boosts testosterone in two important ways. First, specific types of exercise actually cause our body to produce more testosterone. We’ll talk more about those in a bit. Second, exercise helps to increase muscle mass and decrease body fat. As we’ve discussed previously, adipose tissue converts testosterone into estrogen. The less fat we get, the more T we have.
The prevalence of biochemical testosterone deficiency increases with age. This is partly due to decreasing testosterone levels associated with illness or debility but there is also convincing epidemiological data to show that serum free and total testosterone levels also fall with normal aging (Harman et al 2001; Feldman et al 2002). The symptoms of aging include tiredness, lack of energy, reduced strength, frailty, loss of libido, decreased sexual performance depression and mood change. Men with hypogonadism experience similar symptoms. This raises the question of whether some symptoms of aging could be due to relative androgen deficiency. On the other hand, similarities between normal aging and the symptoms of mild androgen deficiency make the clinical diagnosis of hypogonadism in aging men more challenging.

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.
For men with low blood testosterone levels, the benefits of hormone replacement therapy usually outweigh potential risks. However, for most other men it's a shared decision with your doctor. It offers men who feel lousy a chance to feel better, but that quick fix could distract attention from unknown long-term hazards. "I can't tell you for certain that this raises your personal risk of heart problems and prostate cancer, or that it doesn't," Dr. Pallais says.
