Damage to the pelvic floor occurs particularly in long second stages of labour, rapid deliveries, forceps or vacuum deliveries, and in the delivery of large infants. Often damage that occurs during pregnancy and childbirth goes unnoticed at the time, with symptoms only becoming evident following menopause. Recent research has revealed that the pelvic muscles are avulsed from their attachment at the actual time of delivery rather than later atrophy as a result of nerve damage.
