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.

Female Sexual Dysfunction

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective
Official Title: Clitoral Location in Relation to Sexual Function Using Pelvic MRI: A Case-Control Study

Further study details as provided by TriHealth Inc.:

Primary Outcome Measures:
  • clitoral measurements by pelvic MRI [ Time Frame: one year ] [ Designated as safety issue: No ]
    All cases and controls will undergo a pelvic MRI without contrast to assess the clitoral complex.

Secondary Outcome Measures:
  • testosterone levels [ Time Frame: one year ] [ Designated as safety issue: No ]
    Free testosterone and the calculated free androgen index will be compared; additionally, these levels will be correlated with the questionnaire data and clitoral measurements

Biospecimen Retention:   Samples Without DNA
