    The sex hormone testosterone is a genuine aphrodisiac, with higher levels stimulating sexual desire in men and perhaps in women as well, recent research has shown. But the level of testosterone coursing through a person's body has little direct impact on sexual performance, according to the studies, which have discovered a sharp distinction between the chemistry of desire and that of the sexual act itself. The findings on testosterone's role in erotic life are part of a series of recent discoveries emerging from laboratories as sexual desire, an urge at once elusive and compelling, yields its secrets to the cold eye of science. While for several decades scientists have made detailed studies of the psychology and anatomy of sexual arousal itself, it is only within the last few years that desire, the harbinger of arousal, has become a focus for research. The new studies, which aim to aid therapy of individuals and couples who suffer a lack of erotic impulses, are focusing on both the biological and the emotional chemistry of desire. Lief added.

    Sexual motivation is influenced by hormones such as testosterone , estrogen , progesterone , oxytocin , and vasopressin. In most mammalian species, sex hormones control the ability and motivation to engage in sexual behaviours. Sexual motivation can be measured using a variety of different techniques.
