The '''perineal body''' (or '''central tendon of perineum''') is a pyramidal fibromuscular mass in the middle line of the perineum at the junction between the [[urogenital triangle]] and the [[anal triangle]]. In males, it is found between the [[bulb of penis|bulb of the penis]] and the [[Human anus|anus]]; |

The perineal body is essential for the integrity of the [[pelvic floor]], particularly in females. Its rupture during vaginal birth leads to widening of the gap between the anterior free borders of [[levator ani]] muscle of both sides, thus predisposing the child-bearer to [[prolapse|prolapse]] of the [[uterine prolapse|uterus]], [[rectocele|rectum]], or even the [[cystocele|urinary bladder]]. [[Perineal tear]]s and [[episiotomy]] often occur in [[childbirth]] with first-time deliveries, but the risk of these injuries can be reduced by preparing the perineum, often through [[Perineal massage|massage]].{{cite journal |last1=Shipman |first1=M.
