Clinical Trial Summary

Women who are unable to achieve orgasm compared to women who have normal orgasmic function may have different clitoral anatomy and different hormone levels. The investigators hypothesis is that women who have difficulty with orgasm may have a clitoris that is closer to the vagina and may have higher testosterone levels. Pelvic MRI will be used to observe whether clitoral measurements differ between women with normal orgasmic function vs. those with anorgasmia.


Description:

Women unable with anorgasmia and those with normal orgasmic function will undergo pelvic MRI so that clitoral measurements can be taken and then compared for differences.

Outcome

Type Measure Description Time frame Safety issue
Primary Clitoral Measurements Using Pelvic MRI All cases and controls will undergo a pelvic MRI without contrast to assess the clitoral complex. Between day 1-14 (follicular phase) of menstrual cycle No
Secondary Free Testosterone Free testosterone and the calculated free androgen index will be compared; additionally, these levels will be correlated with the questionnaire data and clitoral measurements Between day 1-14 (follicular phase) of menstrual cycle No
Secondary Total Testosterone Free & total testosterone, and the calculated free androgen index will be compared; additionally, these levels will be correlated with the questionnaire data and clitoral measurements Between day 1-14 (follicular phase) of menstrual cycle No
Secondary Free Androgen Index Free androgen index is calculated as the ratio of total testosterone to sex hormone binding globulin (SHBG) Between day 1-14 (follicular phase) of menstrual cycle No
Secondary Female Sexual Function Index (FSFI) Total Score The FSFI is a validated index of sexual function, consisting of a total score and six subscales or domains: desire, arousal, lubrication, orgasm, satisfaction, and pain. The FSFI total is the sum of the six domain scores, each of which is weighted as noted. The FSFI total score can range from 2 to 36, with higher scores indicating better sexual function. A total score of 26.55 has been identified as the ideal cut point for differentiating between normal sexual function and sexual dysfunction. baseline visit No
Secondary FSFI Desire The desire domain of the Female Sexual Function Index (FSFI) consists of two questions and measures the frequency (almost never to almost always) and level (very low to very high) of sexual desire. Item scores range from 1 to 5, with higher scores indicating better sexual function, and the domain score is weighted by a factor of 0.6, such that the domain score can range from 1.2 to 6.0. baseline visit No
Secondary FSFI Arousal The arousal domain of the Female Sexual Function Index (FSFI) consists of four questions and measures the frequency (almost never to almost always) and level (very low to very high) of sexual arousal; and confidence in becoming aroused (very low to very high confidence) and frequency of satisfaction with arousal (almost never to almost always). Item scores range from 0 to 5, with higher scores indicating better sexual function, and the arousal score is weighted by a factor of 0.3, such that the domain score can range from 0 to 6.0. baseline visit No
Secondary FSFI Lubrication The lubrication domain of the Female Sexual Function Index (FSFI) consists of four questions and measures the frequency of lubrication (almost never to almost always), the difficulty in becoming lubricated (extremely difficult to not difficult), frequency of maintaining lubrication (almost never to almost always), and difficulty in maintaining lubrication (extremely difficult to not difficult). Item scores range from 0 to 5, with higher scores indicating better sexual function, and the lubrication score is weighted by a factor of 0.3, such that the domain score can range from 0 to 6.0. baseline visit No
Secondary FSFI Orgasm The orgasm domain of the Female Sexual Function Index (FSFI) consists of three questions and measures the frequency of orgasm (almost never to almost always), difficulty in achieving orgasm (extremely difficult to not difficult), and satisfaction with the ability to reach orgasm (very dissatisfied to very satisfied). Item scores range from 0 to 5, with higher scores indicating better sexual function, and the orgasm score is weighted by a factor of 0.4, such that the domain score can range from 0 to 6.0. baseline visit No
Secondary FSFI Satisfaction The satisfaction domain of the Female Sexual Function Index (FSFI) consists of three questions and measures satisfaction (very dissatisfied to very satisfied) with emotional closeness with partner, sexual relationship with partner, and overall sexual relationship with partner. Item scores range from 0 (or 1) to 5, with higher scores indicating better sexual function, and the satisfaction score is weighted by a factor of 0.4, such that the domain score can range from 0.8 to 6.0. baseline visit No
Secondary FSFI Pain The pain domain of the Female Sexual Function Index (FSFI) consists of three questions and measures the frequency of discomfort or pain during and following vaginal penetration (almost never to almost always), and the level of discomfort or pain (very low to very high). Item scores range from 0 to 5, with higher scores indicating better sexual function, and the pain score is weighted by a factor of 0.4, such that the domain score can range from 0 to 6.0. baseline visit No
