E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the effect of concomitant DHEA compared to placebo in the two treatment groups of OC users on: • Sexual arousability, levels of sexual desire, frequency of sexual fantasies assessed with a Sexual Function Diary (SFD) • Sexual function assessed with the Female Sexual Function Index (FSFI) and the Female Sexual Distress Scale (FSDS) • The vascular component of the sexual arousal response (VPA) determined by vaginal photoplethysmography (VPP) • Number of satisfying sexual events assessed with the SFD • Experience of sexual arousal during self-induced erotic fantasy (SEF) and visual sexual stimulation (VSS)
|
|
E.2.2 | Secondary objectives of the trial |
• To determine the effect of concomitant DHEA on the frequency of and sexual response to sexual activities as assessed with the SFD • To investigate any correlation between VPA and subjective self-assessment measures of the sexual arousal response (SSAQ) • To determine the endocrinologic-sexual response relationship of concomitant DHEA • To evaluate the safety and tolerance of OC use with concomitant DHEA • To compare pretest sexual function (as determined by VPP assessments, SFD, FSFI and FSDS) with that of the two treatment periods
