Fig. 4.

Fractional area coated and leakage volume over time for gels DG1(a), DG2(b), and DG3(c) inserted at position L₀ in the canal with volumes 2 and 4 mL. These results are for a morphometrically small vaginal canal, length d = 12 cm and width w = 3 cm. L₀ = 12 cm corresponds to gel insertion into the fornix, and L₀ = 6 corresponds to gel insertion to the midpoint along the vaginal canal. Gels DG1 (2 mL) and DG2 (both volumes) do not leak. Gel DG3 spreads very rapidly, and both volumes achieve complete coating within 15 min
