Pelvic floor dysfunction is a term used for a variety of disorders that occur when pelvic floor muscles and ligaments are impaired. The condition affects up to 50 percent of women who have given birth. Although this condition predominantly affects women, up to 16 percent of men are affected as well. Symptoms can include pelvic pain, pressure, pain during sex, urinary incontinence (UI), overactive bladder, bowel incontinence, incomplete emptying of feces, constipation, myofascial pelvic pain and pelvic organ prolapse. When pelvic organ prolapse occurs, there may be visible organ protrusion or a lump felt in the vagina or anus.

Common treatments for pelvic floor dysfunction are surgery, medication, physical therapy and lifestyle modifications.

The term "pelvic floor dysfunction" has been criticized since it does not represent a particular pelvic floor disorder. It has therefore been recommended that the term not be used in medical literature without additional clarification.
