The goal of this mini-review article is to summarize the current state of animal research, focusing on the long-term consequences related to adolescent ethanol exposure, with a special emphasis on the behavioral alterations and changes to ethanol sensitivity that can foster high levels of drinking in adulthood.

However, the relative contribution of 5-HT1 A somatodendritic autoreceptors and heteroreceptors in this pro-sexual behavior is unclear. Moreover, it is unclear whether the contribution of somatodendritic 5-HT1 A autoreceptors and postsynaptic 5-HT1 A heteroreceptors alter when extracellular 5-HT levels are chronically increased. Serotonin transporter knockout (SERT-/-) rats exhibit enhanced extracellular 5-HT levels and desensitized 5-HT1 A receptors. These rats model neurochemical changes underlying chronic SSRI-induced sexual dysfunction. We want to determine the role of presynaptic versus postsynaptic 5-HT1 A receptors in the pro-sexual effects of 5-HT1 A receptor agonists in SERT+/+ and in SERT-/- rats. Therefore, acute effects of the biased 5-HT1 A receptor agonists F-13714, a preferential 5-HT1 A autoreceptor agonistivity in both SERT+/+ and SERT-/- rats. Applying these specific pharmacological tools has not solved whether pre- or post-synaptic 5-HT1 A receptors are involved in pro-sexual activity. Moreover, the inactivity of S15535 in male sexual behavior in either genotype was unexpected. The question is whether the in vivo pharmacological profile of the different 5-HT1 A receptor ligan
