	Virgin	Parous	Pregnant	p- value
Ba	0.8±0.3	1±0.4	3.3±1	<0.05*
Bp	0.8±0.3	1±0.4	3.2±0.8	<0.05*

Data are reported as mean ± SEM in cm for n = 3 virgin and n = 6 each for parous and pregnant ewes.

*compared between virgin versus pregnant and parous versus pregnant.

Ba, reference point 3 cm proximal of the external urethral meatus of the anterior wall. Bp, reference point on the posterior wall opposite Ba. C, Cervix. Ns, not significant.
