I. Slow oscillations in vaginal blood flow: alterations during sexual arousal in rodents and humans.
This study investigated slow oscillatory rhythms in vaginal blood flow as a physiological marker of female sexual arousal in rodents, human healthy volunteers, and women with female sexual arousal disorder (FSAD). ⋯ This study demonstrated that slow oscillations in vaginal blood flow are correlated with subjective physiological arousal and display diminished responsiveness in women with FSAD. Slow oscillations in vaginal blood flow are entirely independent of vaginal vasocongestion as women with FSAD demonstrated a normal vasocongestion response to visual sexual stimulation. In conditions where rodents would be expected to be sexually aroused, slow oscillations in vaginal blood flow showed a shift from HFs to LFs. This technique will greatly enhance the investigation of female sexual function both clinically and preclinically.

Clinical Trial
The effects of experimentally-induced sad and happy mood on sexual arousal in sexually healthy women.
In depressed women, common sexual difficulties include decreased sexual desire, sexual arousal and orgasmic difficulties, reduced sexual satisfaction, and reduced sexual pleasure. Experimental research on the influence of depressed mood on genital and subjective sexual arousal in women is scarce. ⋯ The results provide empirical support for the idea that mood can impact on subjective sexual arousal in women.
