![]() ![]() In the late 19th century, Hadra in ‘Lesions of the vagina and pelvic floor’, discussed the possibility of differences in anatomy for a living patient, also noting that the vaginal axis is different in the upper and lower vagina (defined as the sections of the vagina above and below the pelvic diaphragm) ( Hadra, 1888). These studies depict the vagina as a straight hollow tube extending vertically upwards towards the sacral promontory ( Grant, 1943 Eycleshymer and Schoemaker, 1983 Sultan et al., 1993). Our knowledge of female pelvic anatomy is based on old descriptions derived from the dissection of a small number of female cadavers. In comparison with other female pelvic organs, the anatomy of the vagina has been relatively poorly studied. Microbicide, MRI, pelvic anatomy, vagina Introduction Although there is variation among women, variables such as parity, age and height are positively associated with differences in baseline dimensions. CONCLUSION: No one description characterized the shape of the human vagina. Significant positive associations were parity with vaginal fornix length, age with pelvic flexure width and the height with width at the pelvic flexure. Vaginal width was largest in the proximal vagina (32.5 mm), decreased as it passed through the pelvic diaphragm (27.8 mm) and smallest at the introitus (26.2 mm). Mean vaginal length from cervix to introitus was 62.7 mm. The SD surrounding the mean at each anatomical site, and with summary measurements, was significantly smaller with each subject compared with the population. RESULTS: MRI measurements are reproducible. ![]() The influence of potential covariates (age, height, weight and parity) on these dimensions was assessed. Average dimensions were calculated for each woman and for the population. Seventy-seven MRI scans were performed on 28 women before gel application to establish baseline vaginal measurements. METHODS: We combined baseline information collected from five clinical trials using magnetic resonance imaging (MRI) to quantify distribution of a vaginal gel. This study aimed to measure baseline dimensions of the undistended vagina of women of reproductive age.
