A muscle in the pelvic floor. The pubococcygeus contracts during orgasm, and strengthening the muscle can allow for longer, more intense orgasms in some individuals. The muscle also controls the flow of urine, a stronger pubococcygeus can lower a person’s chances of urinary incontinence.

Kegel exercises can strengthen the PC muscle, and both sexes can benefit from a stronger pelvic floor. See “Kegel exercise” for more information.
