Low sexual desire is highly prevalent in the general population and affects adults of all ages. For long that it is recognized that testosterone is an important determinant of sexual desire, but various studies fail to find significant associations of desire with both endogenous and exogenous testosterone, which is congruent with the view that low desire has a multifactorial etiology, and psychological factors likely play a relevant role. Hence, it is important to gain a better understanding of how hormonal and psychological factors interact to generate desire and how this process can go awry.
