Pelvic floor

The pelvic floor is composed of muscle fibers of the levator ani, the coccygeus muscle, and associated connective tissue which span the area underneath the pelvis. The muscles are called the perineal muscles which can contract both voluntarily and involuntarily. The perineal muscles are involved in ejaculation when they are involuntarily contracted. The ischiocavernosus are responsible for the male erection and the bulbocavernosus is responsible for ejaculation.
