Take Home Messages:

  • We have inhibitory mechanisms and excitatory mechanisms related to sexual activity
  • Serotonin tends to be an inhibitor of sexual function
  • Dopamine and Nor-epinephrine are excitatory neurotransmitters

If you use an SSRI, you are getting more serotonin everywhere and more inhibition of all the phases of the sexual response cycle (desire, arousal, orgasmic function and pleasure)

  • Drugs that antagonise 5HT2C are less likely to lead to sexual side effects. e.g Agomelatine, Mirtazapine
