In the future, the measurement of dopamine and serotonin levels in individuals with PFS may elucidate many issues, since the pathways of these neurotransmitters can be altered in neurosteroidogenesis disorders, which in itself would affect sexual behavior in these patients.[44]
“The possibility that epigenetic mechanisms may influence the occurrence of PFS is also discussed, as it appears to affect a limited number of individuals exposed to the drug.44 Giatti et al. even raised the hypothesis that PFS has mechanisms in common with post-selective serotonin reuptake inhibitor syndrome, given the wide range of similar symptoms in the two clinical entities.”
