Effects of Flibanserin on the Pre- and Post-menopausal Female Brain

The purpose of the present study is to understand the neurobiological mechanisms of action underlying sexual desire building on prior work Dr. Stephanie Cacioppo has done in which desire was not manipulated. In the present project, Dr. Stephanie Cacioppo is manipulating desire through Flibanserin (Addyi) vs. placebo and she will be measuring subjective sexual desire as a manipulation check. The investigators will address this goal using a double-blind randomized outpatient design and determine the pre-post neurobehavioral change in the Flibanserin group and investigate the extent to which Flibanserin normalizes brain activity in premenopausal women with HSDD and the extent to which regional brain activation is associated with changes in symptoms and behavior (as measured with self-report measures of sexual desire and/or eye-tracking movements).
