The pelvic floor muscles are a group of muscles which stretch between the pubic bone at the front and the tailbone at the back. Pelvic floor muscles play an important role in bladder and bowel control as well as sexual function.
The urethra (see diagram) and rectum (back passage) pass through the pelvic floor muscles. If these muscles are weak you may have trouble controlling your bladder and bowel. By strengthening these muscles you can improve your bladder and bowel control.
The pelvic floor muscles are also important in sexual function and if they are weak you may have difficulty achieving and maintaining an erection. By strengthening your pelvic floor muscles you may be able to improve your sexual function.
