From Day 1 I've said that Glutamate plays one of the largest roles in human sexual function and definitely in PSSD.
Here I am writing a collection of studies that support this hypothesis.
The idea of PSSD seems greatly compatible with the 'Glutamate-Dysfunction-Hypothesis of PSSD'.
1.) Topiramate in the treatment of compulsive sexual behavior: case report
2.) Natural reward experience alters AMPA and NMDA receptor distribution and function in the nucleus accumbens.
3.) Addiction Circuitry in the Human Brain
4.) Role of nonsynaptic GluN2B-containing NMDA receptors in excitotoxicity: evidence that fluoxetine selectively inhibits these receptors and may have neuroprotective effects.
5.) Genetic and clinical predictors of sexual dysfunction in citalopram-treated depressed patients.
With this being said, there's still a lot of evidence that Dopamine is playing major role, and it probably has most to do with Dopamine facilitation of Glutamate via D1 & D5 Receptors in Human Forebrain [1] and Hypothalamus [2] as well as the Spinal Cord [3] as well as the Dopamine promotion of cyclic AMP / CREBS / Ion cascade [4] [5].
