From: Morphological examination of pelvic floor muscles in a rat model of vaginal delivery
The muscle wet weight of the Pcm was significantly lower in the 1 W, 2 W, and 4 W groups versus the sham group (all p < 0.01). The muscle wet weight of the Icm did not differ significantly among the four groups. Pcm, pubococcygeus muscle; Icm, iliococcygeus muscle; sham group, sham-operated group; 1 W group, 1 week after vaginal distention; 2 W group, 2 weeks after vaginal distention; 4 W group, 4 weeks after vaginal distention. Values are mean ± standard deviation. Statistical analysis Tukey’s test. **Indicates a statistically significant difference (p < 0.01 versus the sham group)
