Past Research

 

The following is an incomplete list of completed studies on the topic of PSSD.

Animal Literature

Neonatal Antidepressant Exposure has Lasting Effects on Behavior and Serotonin Circuitry

(Maciag et al., 2013)

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3118509/

“Here, we show that chronic neonatal (postnatal days 8–21) exposure to citalopram (5 mg/kg, twice daily, s.c.), a potent and highly selective SSRI, results in profound reductions in both the rate-limiting serotonin synthetic enzyme (tryptophan hydroxylase) in dorsal raphe and in serotonin transporter expression in cortex that persist into adulthood. Furthermore, neonatal exposure to citalopram produces selective changes in behavior in adult rats including increased locomotor activity and decreased sexual behavior similar to that previously reported for antidepressants that are nonselective monoamine transport inhibitors.”

Maternal exposure to the antidepressant fluoxetine impairs sexual motivation in adult male mice

(Gouvêa et al., 2004)

https://www.ncbi.nlm.nih.gov/pubmed/18457868

“Global inspection of other cortical areas, such as the hippocampus, also revealed prominent reductions in the SERT-immunoreactive fiber network (data not shown). Moreover, the effects of citalopram on SERT fiber labeling were found to persist into adulthood—PN130 (Figure 7). Similar analysis of clomipramine-treated subjects revealed a nonsignificant effect of drug exposure on cortical SERT innervation; although it should be noted that a trend for decreased immunoreactivity was detected in some individual cases.”

These studies show that treatment with SSRIs cause persistant changes in the expression of SERT in the rodent brain, and that treatment of young rats with SSRIs leads to persistant decreases in sexual activity that carry into adulthood.

But what about in humans?
