Science teaches us that sexual desires are controlled by what is known as the libido — a fancy word for sex drive. Libido is determined by a number of factors that include sociological, psychological, and hormonal influences. The primary hormone responsible for much of the human libido is testosterone. 

Research confirms that low testosterone levels usually mean a lower sex drive. One culprit for low testosterone is excessive amounts of sugar. Excess blood sugar levels can also cause damage to small blood vessels as well as the nerves that control sexual stimulation and response, resulting in what we know as erectile dysfunction. Let’s not forget, testosterone doesn’t just affect men. Imbalanced levels of testosterone in women can reduce desire, increase body fat, lower muscle mass, and increase inflammatory markers that interfere with hormone communication. In turn, high sugar levels can then affect the ability for a woman to experience sexual stimulation and arousal, and can impede the release of vaginal lubricant. (16)(17)(18)

Another master hormone, serotonin, is also involved in maintaining good sexual health. Serotonin is referred to as the body’s “happy” hormone.  While research shows that 95% of serotonin is created in the gastrointestinal track, it is also found in the genitals. It’s suggested that when your serotonin levels dip, your physical response to sexual desires also dips! (19)

Exercise has been shown to improve production of sex hormones like serotonin and reduce stress. Additionally, exercise promotes better circulation, opens arteries and  increases blood flow to both men and women’s sexual organs.  A Harvard study showed that even moderate levels of exercise significantly improved erectile dysfunction in men.  The studies suggest many circulatory conditions that impede sexual function can be reversed by just moving your body a little bit more.
