Peroneal nerve interventions include neurolysis, neuroplasty, or cable graft nerve repair. Injury to it during childbirth may weaken the pelvic floor and contribute to prolapse of the vagina and uterus. The Pelvic Floor - Overview and Function. [15] Measuring the anogenital distance in neonatal humans has been suggested as a noninvasive method to determine male feminisation and thereby predict neonatal and adult reproductive disorders. At the end of pregnancy, expectant mothers may encounter some degree of difficulty expelling the foetus from the vaginal canal. Another important anatomical structure within the anal triangle is the pudendal nerve, which supplies the whole perineum with somatic fibres.
