The perineum is the space between the anus and genitals, and is present in both males and females. The perineum is an erogenous zone and is also known as the taint or gooch in American slang. The perineal body, also called the central tendon of the perineum, is an irregularly shaped fibromuscular structure located at the central point of the perineum. It is composed of collagen and elastic fibres, along with both skeletal and smooth muscle. The perineum is susceptible to injury, which can cause bladder control and sexual function problems.

The perineum is a muscle with many functions, including protecting the nerves used for urination and erections
The perineum is a region of the body between the pubic symphysis (pubic arch) and the coccyx (tailbone). It is a diamond-shaped area that includes the anus and, in females, the vagina. The perineum is the most inferior part of the pelvic outlet and lies between the thighs. It is separated from the pelvic cavity superiorly by the pelvic floor. The perineal body is an irregularly shaped fibromuscular structure located at the central point of the perineum. It is composed of collagen and elastic fibres, along with both skeletal and smooth muscle.
The perineum is supplied by the pudendal nerve, which supplies the whole perineum with somatic fibres, and the internal pudendal artery, which is the chief arterial supplier of the perineum. The pudendal nerve and internal pudendal artery travel along the inner surface of the ischial tuberosities through a "canal" formed by a thickening of the obturator fascia (Alcock's canal). The pudendal nerve gives rise to the cavernosal and dorsal arteries in males, and branches to the vestibular bulb and vagina in females. The perineal region can be divided into the urogenital triangle (anterior half) and the anal triangle (posterior half).
The urogenital triangle contains the mons pubis, labia majora, labia minora, the clitoris, and the vaginal and urethral orifices in females, while in males, it contains the penis and the urethral orifice. The anal triangle contains the anal aperture (opening of the anus) and the ischioanal fossae, which are spaces located laterally to the anus and contain fat and connective tissue that allow for expansion of the anal canal during defecation. The perineum can be subject to various injuries, including straddle injuries, impalement injuries, and tears during childbirth, which can have long-term effects such as bladder control and sexual function problems.

Perineal trauma can cause bladder and bowel problems, as well as sexual dysfunction
The perineum is the space between the anus and the genitals. The human perineum is between the anus and the scrotum in males and between the anus and the vulva in females. The perineum is the most inferior part of the pelvic outlet, lying between the thighs. It is a diamond-shaped area that includes the anus and, in females, the vagina. The perineal body is a fibromuscular mass located at the junction of the urogenital and anal triangles – the central point of the perineum. It contains skeletal muscle, smooth muscle, and collagenous and elastic fibres. The perineum is protected by the pelvic floor muscles, which support the bladder and bowel.
Perineal trauma can also cause bowel control problems. Pelvic floor dysfunction can affect a person's ability to pass stool. This can be due to the muscles becoming too weak, resulting in bowel incontinence, or too tight, causing pain and tension. Perineal injuries can further lead to erectile dysfunction in males. The perineum protects the blood vessels that supply the genitals, and damage to these blood vessels can result in erectile dysfunction, or the inability to achieve or maintain an erection firm enough for sexual intercourse.
Perineal trauma during childbirth is common, with approximately 85% of women experiencing some form of perineal tear during vaginal delivery. This can lead to postpartum morbidity and frustration among women after delivery. Perineal tears can cause severe pain and make it difficult to walk, use the restroom, or perform other daily functions. In some cases, perineal tears may extend beyond the vagina, deep into the adjacent muscle or the anus, causing ongoing muscle problems and affecting the function of the urinary bladder or anal sphincter. Perineal trauma during childbirth can also lead to pelvic organ prolapse later in life as the compensatory mechanisms of the pelvic floor become weakened.

Childbirth can lead to perineal damage, which can be avoided with an episiotomy
The perineum is the space between the anus and the genitals. In males, it is the region between the anus and the scrotum, while in females, it is between the anus and the vulva. The perineum is the most inferior part of the pelvic outlet, lying between the thighs. It is separated from the pelvic cavity superiorly by the pelvic floor. The perineal body, which is located at the junction of the urogenital and anal triangles, acts as a central attachment for perineal muscles and supports the pelvic floor.
Childbirth can lead to perineal damage, such as stretching or tearing of the perineal body, which can result in possible prolapse of pelvic viscera. This damage can be avoided with an episiotomy, a surgical cut in the perineum that prevents uncontrolled tearing of the perineal body. An episiotomy is performed to widen the vaginal opening, making it easier for the baby to pass through. It is particularly recommended when the baby is in distress and needs to be delivered quickly to avoid birth injuries or stillbirth. Additionally, an episiotomy may be necessary to allow for the use of instruments during childbirth, such as forceps or ventouse suction.
While an episiotomy can help prevent severe tears, it does cause damage to the vaginal mucosa. It is important to weigh the benefits against the risks, as the procedure can result in excessive, raised, or itchy scar tissue formation. In some cases, perineal tears may be prevented without an episiotomy by allowing the baby's head to emerge slowly and gently, giving the skin and muscles of the perineum time to stretch. Perineal massage during the last few weeks of pregnancy can also reduce the likelihood of an episiotomy.
If an episiotomy is performed, it is typically done during the second stage of labor when the baby's head has already stretched the vaginal opening. Local anesthesia is used to numb the area, and the incision is made with surgical scissors or a scalpel. After the baby and placenta are delivered, the perineal tissues and muscles are repaired with stitches that will dissolve over time. It is common to experience pain and swelling after an episiotomy, and treatment options include pain relievers, ice packs, and sitz baths.

Perineal sunning is a wellness practice that involves exposing the perineum to sunlight
The perineum is the space between the anus and the genitals in placental mammals. In males, it is between the anus and the scrotum, and in females, it is between the anus and the vulva. It is a diamond-shaped area that includes the anus and, in females, the vagina. The perineum is generally defined as the surface region between the pubic symphysis and the coccyx.
Perineal sunning involves exposing the perineum to the sun for a short period of time. Some people lie on their backs with their legs spread wide in the air, while others face away from the sun and lean over so that the sun's rays have direct access to their perineum. The point of this routine is to give the body an intense dose of vitamin D, resulting in a big energy boost. Some people also claim that perineum sunning can improve sleep, concentration, creativity, and libido, as the technique is said to regulate hormone function in the sex organs.
However, perineal sunning has been labelled as a potentially harmful, non-evidence-based wellness practice by some medical professionals. There is no scientific evidence that exposing the perineum specifically has any benefits, and the high potential for sunburns and cutaneous cancers in this sensitive area is a cause for concern.

The perineal body is a fibromuscular structure located at the central point of the perineum
The perineum is the most inferior part of the pelvic outlet, located between the thighs and separated from the pelvic cavity superiorly by the pelvic floor. The perineum is an erogenous zone, with nerve endings that aid in sexual arousal and response. It is also referred to as the "taint" or "gooch" in American slang.
The perineum is comprised of two triangle-shaped regions: the urogenital triangle and the anal triangle. The urogenital triangle contains the genitals, urethra, and associated muscles, while the anal triangle contains the opening of the anus and the anal sphincter.
The perineal body, also known as the "central tendon of the perineum," is a fibromuscular structure located at the junction of the urogenital and anal triangles, which is the central point of the perineum. This structure contains skeletal muscle, smooth muscle, collagenous and elastic fibres, and acts as a point of attachment for muscle fibres from the pelvic floor and the perineum itself, including the levator ani muscle.
The perineal body is critical for maintaining the integrity of the pelvic floor, especially in females, and it plays a significant role in supporting the pelvic floor. During childbirth, the perineal body can be damaged, leading to possible prolapse of pelvic organs such as the rectum, uterus, or urinary bladder. An episiotomy, a surgical cut in the perineum, can be performed to prevent uncontrolled tearing of the perineal body, although it does cause damage to the vaginal mucosa.
