Interventions/Control_1
10 women were randomized to use placebo vaginal gel twice daily for 5.5 days. The vagina and cervix were examined using standard colposcopy and a new method, OCT, to determine the ability of OCT to detect vaginal/cervical findings not detected by colposcopy.
Interventions/Control_2
20 women were randomized to use the over-the-counter spermicide N-9 as a vaginal gel twice daily for 5.5 days. The vagina and cervix were examined using standard colposcopy and a new method, OCT, to determine the ability of OCT to detect vaginal/cervical findings not detected by colposcopy.

Key inclusion criteria
1. Provides written informed consent
2. Healthy female, 18-45 years of age
3. Pre-menopausal as defined by still having regular menstrual cycles and under age 46 years
4. Willing to discontinue use of vaginal products such as douches, drying agents, vaginal moisturizers, spermicides, tampons, and deodorant pads for 48 hours prior to their appointment and until completion of the study (i.e., from Day -2 to Day 13)
5. Willing to abstain from intercourse for 48 hours prior to Visit 1 until completion of the study (i.e., from Day -2 to Day 13)
Key exclusion criteria
1. History of hysterectomy
2. Gynecologic surgery within the last year
3. History of sensitivity/allergy to any component of the study products, sexual lubricants, spermicides containing Nonoxynol-9, or similar products
4. Current vaginal, cervical, or bladder symptoms such as irritation, burning, itching
5. Current genital pain or discomfort
6. Currently pregnant or within two calendar months from the last pregnancy outcome (delivery, spontaneous abortion, induced abortion)
7. Currently breast-feeding
8. Positive urine pregnancy test
9. Known history of HIV infection
10. Have been diagnosed with any STIs in the 3 months prior to the screening visit or at the screening visit
11. Any evidence of an acute vaginal infection or STI
12. Abnormal Pap smear at screening visit
13. Currently using, or suspected to be using, injection drugs
14. Current use of a vaginal ring or intrauterine device (IUD)
15. Antibiotic use in the two weeks prior to Visit 1
16. Chronic systemic steroid use (does not exclude the use of topical or inhaled steroids)
17. Current diagnosis of cervical cancer or pre-cancer cells
18. Excessive irregular menstrual or inter-menstrual bleeding or unpredictable bleeding pattern (this would interfere with scheduling study visits at a time free from bleeding)
19. Has received an investigational product within 30 days or 5 half-lives (whichever is the longer)
20. Participant has knowledge that her partner is currently having a sexual relationship(s) with another person (male or female)
21. Participant has knowledge that her current partner(s):
a. Has a history of HIV infection
b. Had an STD within the last 6 months
c. Is currently using, or is suspected to be using, injection drugs
22. Participant, in the opinion of the investigator, should not participate in the study

Results
Vincent KL, Stanberry LR, Moench TR, Breitkopf CR, Loza ML, Wei J, Grady J, Paull J, Motamedi M, Rosenthal SL. Optical coherence tomography compared with colposcopy for assessment of vaginal epithelial damage: a randomized controlled trial. Obstet Gynecol. 2011 Dec;118(6):1354-61.
Results: Colposcopy findings, optical coherence tomography scores, and epithelial thicknesses were similar between treatment groups at baseline. After treatment, there were significant differences between the nonoxynol-9 (1.37) and control group (1.15) optical coherence tomography scores (P<.001), indicating epithelial injury, and there was epithelial thinning in the nonoxynol-9 group (237 micrometers) compared with the control group (292 micrometers; P=.008). There were no significant posttreatment colposcopic differences in epithelial disruption between treatment groups, with only increased erythema noted after nonoxynol-9 use (P=.02).
CONCLUSION: Optical coherence tomography detected epithelial disruption and thinning not identified by colposcopy. Vaginal epithelial thickness, a measure previously available only through biopsy, decreased after nonoxynol-9 use, a finding that may contribute to increased susceptibility to human immunodeficiency virus after frequent use. Optical coherence tomography shows promise for the noninvasive clinical assessment of vaginal epithelial damage.
