The perineum is the space between the anus and the genitals, and it contains the perineal muscles. The perineum is located 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 an erogenous zone with multiple nerve endings that help with sexual arousal and response. It also contains structures that help with urination, defecation, and intercourse. The perineal muscles play a crucial role in supporting the pelvic floor and can be injured during childbirth. The perineal body, a tough mass of fibromuscular tissue, is located at the junction of the urogenital and anal triangles, providing a point of attachment for various muscles. The perineal region consists of several muscles, including the superficial and deep transverse perineal muscles, the bulbospongiosus muscle, and the external anal sphincter muscle.

What You'll Learn
The perineum is an erogenous zone
The perineum is the space between the anus and the genitals. 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. The perineum is below the pelvic diaphragm and between the legs. The perineal body is a pyramidal fibromuscular mass in the middle line of the perineum at the junction between the urogenital triangle and the anal triangle. The perineal body is essential for the integrity of the pelvic floor, particularly in females.
The perineum has many nerve endings, which may be why it is an erogenous zone. Erogenous zones tend to be highly sensitive, either because they have more nerve endings or because people do not often touch them. The perineum is a less accessible part of the body, which may be another reason why it is an erogenous zone.
The perineum is also an important area to consider during childbirth. Perineal tears and episiotomy often occur during first-time deliveries. However, the risk of these injuries can be reduced by preparing the perineum, often through massage. The perineum may also rupture during childbirth, leading to a widening of the gap between the levator ani muscles and potentially causing prolapse of the uterus, rectum, or urinary bladder.
The perineum is sometimes referred to as the "taint" or "gooch" in American slang and as the "notcha" in Australian slang. It is important to note that while the perineum is an erogenous zone for some people, this may not be the case for everyone. Every person is different, and some individuals may find that the perineum is not a pleasurable area to touch.

Perineal tears and episiotomy during childbirth
The perineum is the space between the anus and the genitals. In males, it is between the anus and the scrotum, and in females, it is between the anus and the vulva. The perineum is a diamond-shaped area that includes the anus and, in females, the vagina. The perineal body is a pyramidal fibromuscular mass in the middle line of the perineum at the junction between the urogenital triangle and the anal triangle. The perineal body contains skeletal muscle, smooth muscle, and collagenous and elastic fibres.
Perineal tears and episiotomies are common during childbirth, especially for first-time mothers. The perineum needs to stretch a lot during childbirth, and it may tear. Tears happen spontaneously as the baby stretches the vagina and the perineum during birth. Tears can be minor, but some are more significant as they affect the anus. These are called third or fourth-degree tears and will be stitched in the operating theatre. The most severe tears can lead to anal incontinence.
An episiotomy is a cut made by a healthcare professional into the perineum and vaginal wall to make more space for the baby to be born. Episiotomies are done with consent and are only performed if the baby needs to be born quickly, often during an instrumental birth, or if there is a risk of a serious perineal tear. Episiotomies can help prevent severe tears and speed up delivery. After an episiotomy or a tear, the healthcare professional will carefully examine the vagina, perineum, and rectum to see if there is a tear and advise if stitches are needed.
To avoid perineal tears during childbirth, a midwife can ask the mother to stop pushing and to pant or puff a couple of quick short breaths, allowing the baby's head to emerge slowly and gently, giving the skin and muscles of the perineum time to stretch without tearing. Massaging the perineum in the last few weeks of pregnancy can also reduce the chances of having an episiotomy during birth.

Perineal muscles in males and females
The perineum is the space between the anus and the genitals. In males, the perineum is between the anus and the scrotum, and in females, it is between the anus and the vulva. The perineum is a diamond-shaped area that includes the anus and, in females, the vagina. The perineal body is the central fibrous skeleton of the perineum, with a pyramid shape in males and a wedge shape in females. The perineal body is an important structure that helps strengthen the pelvic floor and provides attachments for various muscles.
The pelvic floor muscles are a group of muscles that stretch from the pubic bone at the front to the coccyx (tailbone) at the back, and they play a crucial role in both males and females. In males, the pelvic floor muscles support the bladder and bowel, helping to maintain continence and sexual function. Weakened pelvic floor muscles can lead to stress incontinence, urge incontinence, and bowel control issues. However, these muscles can be strengthened through specific exercises, such as squeezing the ring of muscle around the anus and lifting the pelvic floor muscles.
In females, the pelvic floor muscles are also essential for supporting the bladder and bowel. Additionally, the pelvic floor plays a critical role in childbirth. The perineal body may rupture during vaginal delivery, predisposing the woman to prolapse of the rectum, uterus, or urinary bladder. Perineal tears and episiotomy are common during childbirth, especially in first-time deliveries, but their risk can be reduced by preparing the perineum through massage.
The perineum region contains several important muscles, including the external anal sphincter muscle, which is responsible for opening and closing the anus, and the external urethral sphincter muscle fibres. The bulbospongiosus muscle is another important muscle in the perineal region, and it has different functions in males and females. In females, it acts as a tear-resistant body between the vagina and the external anal sphincter, while in males, it lies between the bulb of the penis and the anus.
The perineum region also includes the urogenital triangle, which contains the external urogenital organs, and the anal triangle, which contains the terminal segment of the anal canal and the anal sphincters. These triangles are separated by the line of the transverse muscles of the perineum, which contributes to the formation of the perineal body.

Perineal fascia and its subdivisions
The perineum is the space between the anus and the genitals. The perineal region extends from the skin to the inferior fascial surface of the pelvic floor. The perineum is subdivided into two triangles: the anterior urogenital triangle and the posterior anal triangle.
The perineal fascia is a continuity of the abdominal fascia that has two components: the superficial perineal fascia and the deep perineal fascia. The superficial perineal fascia is attached to the margins of the ischiopubic rami at its lateral end and the posterior margin of the perineal membrane at its posterior end. In males, the fascia also lines the skin of the scrotum, which contains the dartos muscle. In both sexes, the fascia becomes continuous with the membranous layer of the superficial fascia of the anterior abdominal wall (also called Scarpa's fascia).
The deep perineal fascia firmly overlies the muscles of the superficial perineal pouch. It attaches to the perineal membrane and the perineal body posteriorly, the suspensory ligament of the penis or the clitoris anteriorly, and the ischiopubic rami laterally. The deep perineal fascia also covers the superficial perineal muscles and protruding structures, such as the penis and clitoris.
The perineal membrane, also called the inferior fascia of the urogenital diaphragm, is a layer of tough fascia that is perforated by the urethra and the vagina in females. It divides the urogenital triangle into the deep perineal space (above the membrane) and the superficial perineal space (below the membrane). The perineal membrane is thickened at its apical end to form the transverse perineal ligament. The superficial perineal space is further divided into the subcutaneous and superficial perineal pouch by the three fascia layers: the superficial fascia of the perineum, the deep perineal fascia, and the perineal membrane.
The perineal body is the central fibrous skeleton of the perineum, with a pyramid shape in the male body and a wedge shape in the female body. It is located at the junction of the urogenital and anal triangles – the central point of the perineum. This structure contains skeletal muscle, smooth muscle, and collagenous and elastic fibres. The perineal body helps strengthen the pelvic floor and provides attachments to muscles such as the bulbospongiosus, deep transverse perineal muscle, and external anal sphincter.

Perineal body and its functions
The perineum is the space between the anus and the genitals. In males, the perineum is between the anus and the scrotum, and in females, it is between the anus and the vulva. The perineal body is a fibromuscular structure located in the midline of the perineum at the junction of the urogenital triangle and the anal triangle. It is also referred to as the "central tendon of the perineum". The perineal body is composed of collagen and elastic fibres, along with both skeletal and smooth muscle. It acts as a point of attachment for muscle fibres from the pelvic floor and the perineum itself.
The perineal body serves as a central convergence point where fibres of several muscles interlace and overlap. These include the bulbospongiosus, external anal sphincter, both the superficial and deep transverse perineal muscles, as well as smooth and skeletal muscle strands from the external urethral sphincter. The perineal body is critical for maintaining the integrity of the pelvic floor, especially in females. Its rupture during vaginal birth can lead to a widening of the gap between the anterior free borders of the levator ani muscle of both sides, thus predisposing the mother to prolapse of the uterus, rectum, or even the urinary bladder.
The perineal body also helps to strengthen the pelvic floor and provides attachments to several muscles. These include the bulbospongiosus, deep transverse perineal muscle, compressor urethrae, external anal sphincter, internal anal sphincter, external urethral sphincter, levator ani muscle, and rectourethralis. The perineal body is an important landmark during the surgical resection of anorectal tumours, ensuring the achievement of a tumour-free circumferential resection margin.
The perineum is an erogenous zone and is also known as the "taint" or "gooch" in American slang, and as the "notcha" in Australian slang. Perineum sunning is a wellness practice that involves exposing the perineum to sunlight. However, there is no scientific evidence that this practice promotes any health benefits, and it may increase the risk of skin cancers. Doctors recommend safer alternatives such as relaxation, meditation, and mindfulness to achieve the same desired benefits.
