Recently, the results of a study on obese individuals and an impaired sex drive were results. The clinical trial was conducted by clinical psychologist and director of behavioral health, Martin Binks, PhD, of Duke University's Diet and Fitness Center. The findings of the trial demonstrated that a third of the obese subjects suffering weight control experienced a low libido, an impaired sex drive, performance issue, or even all three. Furthermore, the research depicted how problems were stemmed from physical conditions that are prevalent with obesity.

The premature symptoms of type 2 diabetes such as high cholesterol and insulin resistance were found to impact sexual performance. These medical conditions have been found to impacts desire (specifically in men). The link between sexual ability and obesity has been found to impair the tiny arteries of the penis to power out; especially when vessel-clogging fatty deposits begin to develop. The correlation between male infertility and excess weight were noted by the director of sexual health and male infertility, Andrew McCollough, MD, of the NYU Medical Center in New York.

The same finding has been found to apply in the obese female gender. In the clitoris, the width of the blood vessels is impacted by the same kind of blockages that impact normal blood flow to the penis in men. The correlation was noted by director of sexual medicine, Susan Kellogg, PhD, at the Pelvic and Sexual Health Institute of Graduate Hospital in Philadelphia.

The blood flow dilemma is making the matters worse for both genders. More body fat represents elevated levels of a natural chemical known as SHBG (sex hormone binding globulin). Medical experts theorize that heightened levels of testosterone are bound to SHBG which reduces the desire for sexual intimacy.
