Abstract: Pelvic floor dysfunction （PFD） is strongly correlated with pregnancy and childbirth. The mechanisms of pelvic floor injury leading to PFD are largely unknown. The female pelvic floor can undergo a series of remodeling to maintain the anatomic and functional stability. The pelvic floor remodeling contains nerve, muscle and connective tissue; it is also carried through the whole perinatal period and shows individual difference. Study of female pelvic floor remodeling is beneficial to demonstrating the pathogenesis of PDF and providing effective therapy.
