The answer is the third one: Serotonin.

Explanation for each option:

  • Dopamine: This neurotransmitter is generally associated with the promotion of sexual function. It plays a role in the reward and pleasure centers of the brain, and increased dopamine levels are often linked to increased sexual desire and arousal.

  • Oxytocin: Often referred to as the "love hormone," oxytocin is associated with bonding, sexual reproduction, and during and after childbirth. It generally has a positive effect on sexual function and intimacy.

  • Serotonin: This neurotransmitter is known to exert an inhibitory effect on sexual function. High levels of serotonin can decrease sexual desire and arousal, which is why some antidepressants that increase serotonin levels can have sexual side effects.

  • Glutamate: This is the main excitatory neurotransmitter in the brain and is not typically associated with inhibiting sexual function. It generally plays a role in promoting neural activity.

In summary, serotonin is the neurotransmitter that exerts an inhibitory effect on sexual function.
