Table 3. Uniaxial Tensile Biomechanical Properties of Vaginal Tissue.

The biomechanical properties (tensile strength, maximum strain, tangent modulus, and strain-energy density) of nulliparous and parous NHP are presented as mean ± S.D.

	Nulliparous (n=5)	Parous (n=6)	p-value
Tangent Modulus (MPa)	27.0 ± 11.5	12.8 ± 6.6	0.03
Tensile Strength (MPa)	2.4 ± 0.53	0.96 ± 0.26	<0.001
Maximum Strain (%)	19.0 ± 5.4	16.0 ± 5.0	0.24
Strain-Energy Density (MPa)	0.18 ± 0.08	0.07 ± 0.02	0.006

A Student's t-test (p<0.05) was used to determine statistical significance between each group.
