RESUMO
OBJECTIVE: To provide baseline data for the anatomy of the external female genitalia and to investigate the correlation between those measurements and sexual function and genital perception. MATERIALS AND METHODS: This prospective cohort study consisted of 208 healthy premenopausal women. The Female Sexual Function index (FSFI) and the Female Genital Self-image scale (FGSIS) questionnaires were administered. Participants were divided into two groups according to their female sexual dysfunction (FSD) status. External genital measurements and anterior and posterior vaginal length were measured. RESULTS: The external female genital measurements were (cm, mean ± standard deviation): clitoral prepuce length 2.05±0.48; clitoral glans length 0.87±0.21; clitoral glans width 0.60±0.15; clitoris to urethra 2.24±0.55; anterior fornix depth 7.75±0.92; posterior fornix depth 9.25±0.75; labia minora width, right 2.12±0.86, left 2.20±0.96. A weak negative correlation was found between total FGSIS scores and clitoral prepuce length (p=0.01, r=-0.17), whereas a weak positive correlation was seen between total FGSIS scores and anterior-posterior vaginal lengths (p=0.04, r=0.13; p=0.02, r=0.15, respectively). No statistically significant difference was found between the genital measurements of participants with FSD (n=82, 39.4%) and those without FSD (n=126, 60.6%), and the total FSFI scores and orgasm subdomain scores. CONCLUSION: The female genital measurements were found to be distributed over a wide range. Although the relationship between genital measurements and genital perception varied, no significant relationship was found between genital measurements and sexual functions or orgasm. These findings suggest that a more cautious approach should be taken towards genital surgeries for cosmetic purposes.
RESUMO
OBJECTIVE: To provide data on the anatomical dimensions of adult female genitalia and to investigate the possible association of vulvar morphology and sexual function. STUDY DESIGN: This cross-sectional prospective cohort study, using measurements of the external genitalia was performed in a day-care unit of a tertiary, university-affiliated medical center from 2013 to 2014. Thirty-two premenopausal women aged 20-51 years, undergoing gynecological procedures under general anesthesia (not involving the external genitalia) were asked to respond to both a local general data questionnaire and a validated sexual function questionnaire (PISQ-12). Based on reported orgasmic performance during sexual intercourse, patients were divided into two groups, and the measured genital features were compared. RESULTS: Age, body mass index, parity and sexual activity history were recorded. A wide range of values was noted for each measurement. There was no statistically significant association between external genitalia measurements and age, parity or sexual activity. There was no statistically significant difference in any of the external genitalia measurements between the groups. CONCLUSION: Wide variability exists in the appearance of female external genitalia. Sexual function does not appear to be associated with genital dimensions. This information is important for both women and surgeons when considering cosmetic vulvar surgery.
