Cognitive abilities differ between males and females and these differences are present from childhood. In broad terms, girls have stronger verbal skills than boys who tend to have stronger skills related to spatial ability (Linn and Petersen 1985). It is thought that the actions of sex hormones have a role in these differences. Reviewing different cognitive strengths of male versus female humans is not within the scope of this article but the idea that cognition could be altered by testosterone deserves attention.
Studies of the effects on cognition of testosterone treatment in non-cognitively impaired eugonadal and hypogonadal ageing males have shown varying results, with some showing beneficial effects on spatial cognition (Janowsky et al 1994; Cherrier et al 2001), verbal memory (Cherrier et al 2001) and working memory (Janowsky et al 2000), and others showing no effects (Sih et al 1997; Kenny et al 2002). Other trials have examined the effects of testosterone treatment in older men with Alzheimer’s disease or cognitive decline. Results have been promising, with two studies showing beneficial effects of testosterone treatment on spatial and verbal memory (Cherrier et al 2005b) and cognitive assessments including visual-spatial memory (Tan and Pu 2003), and a recent randomized controlled trial comparing placebo versus testosterone versus testosterone and an aromatase inhibitor suggesting that testosterone treatment improves spatial memory directly and verbal memory after conversion to estrogen (Cherrier et al 2005a). Not all studies have shown positive results (Kenny et al 2004; Lu et al 2005), and variations could be due to the different measures of cognitive abilities that were used and the cognitive state of men at baseline. The data from clinical trials offers evidence that testosterone may be beneficial for certain elements of cognitive function in the aging male with or without cognitive decline. Larger studies are needed to confirm and clarify these effects.
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.
Zinc deficiency also negatively affects testosterone levels, according a 2014 article in the Journal of Plant Biochemistry and Physiology. The authors of this review note that zinc supplementation can increase circulating testosterone in some populations. In fact, daily supplementation with typical doses may double testosterone within a few months.
Magnesium deficiency is another widespread problem in our country. While this makes you prone to stress and muscle cramps, it also starves your body’s endocrine system of a vital mineral it needs for testosterone production. We wrote another article on how magnesium alone can send your testosterone levels through the roof. You have to check it out.
If you’re a frequent reader here in AM, you already know that increased dietary fat intake is directly correlated with increased testosterone production. And not only that, but the types of fat that increase T seem to be saturated fats (SFAs) and monounsaturated fats (MUFAs), while polyunsaturated (PUFAs) actually tend to lower testosterone (more here).

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.


This causes your body to burn fat for the next 36 hours to replace your body’s vital energy stores. It addition to increasing your T-levels, it can help burn between 3–9 times more fat, lower your resting heart rate, lower blood pressure, keep your brain young by increasing circulation, and aids in detoxification by stimulating the lymphatic system.
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.
A notable study out of Wayne State University in Indiana found that older men who had a mild zinc deficiency significantly increased their testosterone from 8.3 to 16.0 nmol/L—a 93 percent increase—following six months of zinc supplementation. Researchers of the study concluded that zinc may play an important role in modulating serum testosterone levels in normal healthy men.6

One study found that men who took 3,332 international units (IU) of vitamin D daily for one year significantly increased their testosterone levels. But vitamin D supplements may only work for men who are severely deficient in this specific vitamin. Another study found that men without a vitamin D deficiency had no increase in testosterone levels after taking vitamin D.
There are positive correlations between positive orgasm experience in women and testosterone levels where relaxation was a key perception of the experience. There is no correlation between testosterone and men's perceptions of their orgasm experience, and also no correlation between higher testosterone levels and greater sexual assertiveness in either sex.[34]

1) Eat a good diet daily consisting of 10 servings of fresh vegetables (recommend juicing, and go heavy on the carrots & broccoli), lots of cholesterol in the form of eggs, butter, bacon, avocados, good fat, and take in moderate levels of protein. Avoid all trans fat and limit sugars, carbohydrates and any grains. Lastly, snack on nuts throughout the day between meals to keep your metabolism going.


Also, due to the intake of these synthetic substances, men start behaving in a very excited way, as well as demonstrate high levels of aggression and even violence. So, the men’s behavior may be antisocial. In addition, the men will experience breast enlargement and testicular shrinkage. The other adverse effects include hypertension, tumor growth, heart attacks and strokes, as well as development of liver disorders. It’s obvious that the numerous dangers of steroid use far outweigh a few benefits which they bring.
Vitamin D, a steroid hormone, is essential for the healthy development of the nucleus of the sperm cell, and helps maintain semen quality and sperm count. Vitamin D also increases levels of testosterone, which may boost libido. In one study, overweight men who were given vitamin D supplements had a significant increase in testosterone levels after one year.5
The reasons for considering such therapy become evident from the many associations, indicated above, that reduced testosterone has with a variety of both physiological functions (bone metabolism, muscle mass, cognitive function, libido, erectile function) and pathophysiological states (metabolic syndrome, diabetes mellitus, obesity, insulin resistance, autoimmune disease). Although a definitive long-term, large scale placebo-controlled double-blind study of testosterone therapy in the aging male has not yet been carried out, multiple shorter-term trials have suggested improvement by testosterone with a resultant enhancement of muscle mass, bone density, libido, erectile function, mood, motivation and general sense of well-being.

4. Foods rich in vitamin A. Vitamin A is more commonly known for its association with eyesight improvement, but it is also a vitamin supplements the production of testosterone. The June 2004 issue of the Clinical Endocrinology journal published research conducted by Israel’s Kaplan Medical Center. This study involved Israeli boys that had delays in puberty. These boys were given Vitamin A supplements and foods rich in Vitamin A over the course of 6 months, and most of them showed an improvement with their testosterone levels. If you want to boost the level of testosterone in your body, food types that are rich in Vitamin A are carrots, sweet potatoes, squash, cantaloupe and eggs.
“I'm a truck driver and for 13 hours a night I sit in my truck and I drive. Out of boredom, I'd stop and eat. That was all until Andro400 – ever since then my life has changed. I started out weighing 341 pounds, and since taking Andro400 I've dropped 85 pounds! There's no cravings – I actually don't even think about food anymore. One thing that Andro400 said on the radio ad is it attacks belly fat – well let me tell you it did – the 2nd month is where I saw a drastic change in the size of my stomach. I've lost 6 inches! I'm sleeping better. My knee pain went away. I've had some lower back issues and that went away, and I can only attribute that to Andro400. It's a Life Changer for me!”

A: Androderm comes in the form of a transdermal patch and is used for testosterone replacement therapy in patients who have insufficient levels of testosterone. Testosterone is a hormone produced in the body that plays a key role in many physiological processes in men. In some men, however, the body does not produce enough of the hormone, resulting in a variety of symptoms including decreased libido, erectile dysfunction, muscle loss, anemia and depression, among others. Androderm helps treat these symptoms and raise low testosterone levels by delivering therapeutic amounts of the hormone, which are absorbed through the skin. According to the prescribing information for Androderm, depression was a reported side effect of the medication. Other common side effects of Androderm include itching and redness at the application site, prostate abnormalities, headache, and burning or hardening of the skin at the application site. Less common side effects of Androderm include reduced libido (sex drive), fatigue, high blood pressure, anxiety, confusion, increased appetite, and body pain. For more specific information, consult with your doctor for guidance based on your health status and current medications, particularly before taking any action. Your physician can determine if your dosage of the medication needs to be adjusted or if an alternative medication should be considered. Lori Poulin, PharmD
