High levels of which neurotransmitter might indicate sexual arousal?

Dopamine plays a significant role in the process of sexual arousal, as it is closely associated with the brain's reward system. This neurotransmitter is involved in motivation and the sensation of pleasure, which are crucial components of sexual desire and arousal. When dopamine levels rise, they can enhance sexual excitement and increase libido.

Research supports the association between elevated dopamine levels and both physical arousal and the subjective experience of sexual desire. This connection is further emphasized by the fact that certain pathways in the brain, which are activated during sexual arousal, rely heavily on dopamine activity. Therefore, higher levels of this neurotransmitter correlate positively with feelings of sexual arousal and motivation to engage in sexual activity.
