While testosterone stimulates a man’s sex drive, it also aids in achieving and maintaining an erection. Testosterone alone doesn’t cause an erection, but it stimulates receptors in the brain to produce nitric oxide. Nitric oxide is a molecule that helps trigger a series of chemical reactions necessary for an erection to occur. When testosterone levels are too low, a man may have difficulty achieving an erection prior to sex or having spontaneous erections (for example, during sleep).
Testosterone insufficiency has been associated with HIV infection in men (Dobs et al 1988). Early reports suggested that testosterone therapy may have an ameliorating effect on both depression and decreased energy in HIV infected men, even if testosterone levels were not reduced (Rabkin et al 1999; Grinspoon et al 2000; Rabkin et al 2000). Both depression and fatigue, however, are common features of HIV-positive men and may be associated with factors other than reduced levels of testosterone. The disease itself may induce depression and fatigue may be a consequence of the disease, per se, or of some of the medications used to control HIV.
Men can experience a range of symptoms if testosterone decreases more than it should. Low testosterone, or low T, is diagnosed when levels fall below 300 nanograms per deciliter (ng/dL). A normal range is typically 300–1000 ng/dL, according to the U.S. Food and Drug Administration. A blood test called a serum testosterone test is used to determine your level of circulating testosterone.
As you cut these dietary troublemakers from your meals, you need to replace them with healthy substitutes like vegetables and healthy fats (including natural saturated fats!). Your body prefers the carbohydrates in micronutrient-dense vegetables rather than grains and sugars because it slows the conversion to simple sugars like glucose, and decreases your insulin level. When you cut grains and sugar from your meals, you typically will need to radically increase the amount of vegetables you eat, as well as make sure you are also consuming protein and healthy fats regularly.
One of the most important nutrients that can help boost testosterone levels is vitamin D3. In 2011, the results of a study published in the journal Hormone and Metabolic Research announced that vitamin D supplementation boosts testosterone naturally in overweight men by up to 30 percent. (12) This is pretty exciting because research has shown that vitamin D3 is also linked to helping to prevent and treat cancer! (13)
How do you boost testosterone naturally? Testosterone is a male sex hormone. Low levels can cause changes to the distribution of body fat and muscle strength. Testosterone reduces with age, but people can boost it with lifestyle changes, including diet and exercise. Adequate sleep, nutritional supplements, and stress reduction may also help.
