The Vulva: Anatomy, Function, and Aesthetic Diversity

External Anatomy of the Vulva

×

The vulva’s external anatomy is made up of several distinct parts, each with its own structure and purpose. These parts together form the outer genital area and can vary greatly in appearance from person to person.

Mons Pubis (Pubic Mound)

The mons pubis (or pubic mound) is the soft, fatty pad of tissue that lies over the pubic bone at the front of the vulva. It forms the uppermost part of the vulvar area, creating a gentle mound between the lower abdomen and the genital openings. After puberty, the mons pubis becomes covered with pubic hair. Functionally, this padded area cushions the pubic bone and helps absorb impact during sexual intercourse. Some people also find that pressure on the mons pubis during arousal can contribute to pleasurable sensations, while others might not feel much or could even experience slight discomfort with pressure.

Labia Majora (Outer Lips)

The labia majora are the two outer lips or folds of skin that run along the sides of the vulval opening. They are typically thicker and fleshier than the inner lips, and after puberty they usually have pubic hair on their outer surface. Internally, the labia majora contain fatty tissue and some erectile tissue, meaning they can swell with increased blood flow when a person is aroused. The primary role of the labia majora is to protect the more delicate structures of the vulva, such as the inner lips and vaginal opening, by encasing or covering them. Labia majora come in different shapes and sizes for everyone – there is a wide range of normal variation in how long, short, flat, or full they appear.

Labia Minora (Inner Lips)

The labia minora are the inner lips of the vulva, situated just inside the labia majora. These inner folds are thinner, hairless skin folds that extend from the top of the vulva (at the clitoris) down toward the bottom, ending at the perineum (the area between the vaginal opening and the anus). The upper part of each labium minus joins at the clitoris to form the clitoral hood, a fold of skin that partly covers and protects the clitoris. The labia minora are rich in blood vessels and nerve endings, so they become engorged (swollen with blood) during sexual arousal and are highly sensitive to touch. Just like the outer lips, the appearance of inner lips varies greatly: in some individuals the labia minora are small and tucked mostly inside the outer labia, while in others they are larger and may protrude past the labia majora (one side may even be longer or differently shaped than the other). All such variations are normal and healthy.

Clitoris

The clitoris is a small, incredibly sensitive organ located at the top of the vulva where the inner lips meet. Externally, only the glans clitoris (a pea-sized visible tip) can be seen, nestled under the clitoral hood. Despite its small external size, the clitoris is often described as the pleasure center of the vulva: it contains a dense concentration of nerve endings (estimated to be more than 10,000) – more than any other part of the human body. The clitoris actually has an internal structure as well (with a shaft and “roots” or crura that extend inside the body), but its sole function is to facilitate sexual arousal and orgasm. Most people with a clitoris require direct or indirect clitoral stimulation to reach orgasm. Because it is so sensitive, direct pressure on the exposed glans can sometimes feel overwhelming or even uncomfortable, so the clitoral hood and surrounding tissues help modulate sensations. In summary, the clitoris is a specialized organ dedicated entirely to sexual pleasure.

Urethral Opening

The urethral opening is a small opening located just below the clitoris and above the vaginal opening. It is the external end of the urethra, the tube that carries urine from the bladder out of the body. This opening (also called the urinary meatus) is usually a tiny slit or pin-point hole that isn’t very noticeable, but it’s a crucial part of the vulva because it’s where urine (pee) exits the body. The urethral opening does not play a direct role in sexual reproduction, but it is part of the vulvar anatomy. Just inside the urethral opening are the Skene’s glands (sometimes nicknamed the female prostate). These small glands produce a thin, milky fluid that helps lubricate the urethral opening and may help prevent urinary tract infections by flushing the area when you urinate. (Skene’s glands can also release fluid during certain types of arousal or orgasm, a phenomenon sometimes called female "squirting", but experiences vary.) Overall, the labia and surrounding tissues help keep the urethral opening protected and clean.

Vaginal Opening (Introitus)

The vaginal opening is the entrance to the vagina, located below the urethral opening. This is the external gateway to the vagina – a flexible, muscular canal inside the body. Through the vaginal opening (also called the introitus), several important functions occur: menstrual blood exits the body during a period, penetrative sexual intercourse can take place, and it is the channel through which a baby is delivered during vaginal childbirth. The vaginal opening is typically partially covered or surrounded by a rim of tissue that may include the hymen (a thin membrane that, if present, usually has an opening and can be stretched or torn the first few times something is inserted into the vagina). On either side of the vaginal opening are the Bartholin’s glands, which secrete lubricating fluid. These glands release mucus that helps keep the vulva and vagina moist, especially during sexual arousal, to reduce friction. The outer one-third of the vaginal canal (just inside the opening) contains many nerve endings and is quite sensitive, contributing to sexual pleasure when stimulated.

Perineum

The perineum is the area of skin and soft tissue between the vaginal opening and the anus. It forms the bottom border of the vulva. If you run your finger downward from the vagina toward the back, the perineum is that short bridge of flesh before you reach the anus. The perineum provides structural support for the pelvic floor and during sexual activity it can be involved (for instance, it may be stimulated externally or may stretch). The perineum is especially noteworthy in childbirth: it often stretches significantly to allow the baby to emerge, and in some cases it may tear or be deliberately cut (an episiotomy) to aid delivery. After birth, this area usually heals, but caring for the perineum is an important part of postpartum recovery. In everyday life, the perineum doesn’t require any special attention beyond normal hygiene, but it’s helpful to know this part of your anatomy, especially when discussing childbirth or injuries.

Internal Genital Structures

While the vulva refers to the external genital structures, it’s connected to several internal organs that play roles in reproduction and sexual health. 

Vagina

The vagina is an internal muscular canal that extends from the vaginal opening (in the vulva) up to the cervix. It is sometimes called the birth canal. The vagina is quite flexible and can lengthen or widen during arousal or childbirth. Its functions include allowing for menstrual fluid to leave the body, serving as the receptacle for a penis or other objects during intercourse, and providing the passageway for a baby during a vaginal birth. In other words, the vagina enables menstruation, sexual penetration, and childbirth. It also has self-cleaning capabilities (via vaginal discharge) and maintains an acidic environment to protect against infections. (Importantly, as noted, the vagina is internal, whereas the vulva is external – a distinction that helps clarify why the correct terminology matters).

Cervix

The cervix is the lower, narrow part of the uterus that protrudes into the top of the vagina. It acts as a gateway between the vagina and the uterus. The cervix has a small opening (the os) that allows menstrual blood to flow out from the uterus into the vagina, and it allows sperm to enter the uterus from the vagina. During childbirth, the cervix dilates (opens) to about 10 centimeters to let the baby pass from the uterus into the vaginal canal. In simple terms, the cervix connects the uterus to the vagina – it’s essentially the neck of the uterus. Under normal conditions you can’t see the cervix without a medical exam (it’s visible during a gynecological exam with a speculum), but you might feel it as a small nub or donut-like structure high inside the vagina. The health of the cervix is monitored through Pap tests, which check for cervical cell changes.

Uterus

The uterus (or womb) is a pear-shaped, muscular organ located in the pelvis, above the vagina and cervix. It’s about the size of a fist (when not pregnant) and is where a fertilized egg can implant and grow into a fetus. The uterus has thick muscular walls that are capable of strong contractions (which happen during labor as well as menstrual cramps). Biologically, the uterus is central to pregnancy – it is where a baby develops until birth. Each month, the lining of the uterus (the endometrium) builds up in preparation for a potential pregnancy and then sheds during menstruation if no fertilization occurs. So the uterus also plays a key role in the menstrual cycle. The top of the uterus connects to the fallopian tubes (which carry eggs from the ovaries), and the bottom of the uterus is the cervix. Though the uterus isn’t part of the vulva, its functions (menstruation and childbirth) are directly related to the vulva because the vulvar openings allow menstrual blood out and babies out.

Understanding these internal structures alongside the vulva gives a complete picture of female genital anatomy. The vulva is the external gateway to this reproductive system – it’s where internal and external meet.

Biological Functions of the Vulva

The vulva is not only a collection of skin folds and small organs; it also serves several biological functions that are important for health, reproduction, and sexuality. Here are some of the key functions of the vulva and its components:

• Protection: The vulva acts as a protective barrier for the internal reproductive tract. In fact, the word vulva comes from a Latin term meaning "wrapper" or "covering", emphasizing its role in covering the more sensitive internal organs. The labia majora (outer lips) in particular help shield the inner labia, vaginal opening, and urethral opening from dirt, friction, and pathogens in everyday life. This protection can help reduce the risk of injury or infection to the vagina and urethra. Essentially, the vulva is the first line of defense for the female reproductive system.
• Sexual Arousal & Pleasure: A major function of the vulva is enabling sexual pleasure. The vulva contains structures (like the clitoris, inner labia, and vaginal opening) rich in nerve endings, erectile tissue, and blood vessels that respond to sexual stimulation. During arousal, the clitoris and labia swell with blood, and the entire vulvar area becomes more sensitive. Most people with vulvas rely on stimulation of the vulvar region – especially the clitoris – to reach orgasm. The vulva’s ability to become lubricated (see below) and engorged increases pleasure and comfort during sexual activity. In short, the vulva is central to sexual arousal, with the clitoris being the only human organ whose exclusive purpose is to provide sexual pleasure.
• Lubrication: The vulva helps facilitate comfortable sexual activity through natural lubrication. Bartholin’s glands, located near the vaginal opening, secrete mucus that moistens the vulvar vestibule (the area around the vaginal opening). Similarly, the Skene’s glands near the urethral opening also contribute fluids. Together with lubrication from the vaginal walls, these secretions keep the vulva and vagina supple and reduce friction during intercourse or other activities. Lubrication is crucial for preventing injury to delicate tissues and for making sexual experiences more comfortable and enjoyable. If the vulva is aroused, you’ll typically notice increased moisture in the area – that’s the body’s natural way of preparing for penetration or stimulation.
• Urination: The vulva contains the urethral opening, which means it plays a role in the body’s urinary function. Urination (peeing) is facilitated by the vulva simply by providing an exit point for urine. The design of the vulvar anatomy helps direct urine flow out and away from the body. While the vulva itself doesn’t produce urine (the bladder and kidneys handle that), maintaining healthy vulvar skin and flora can help prevent irritation or urinary tract infections. For example, the proximity of the vulvar structures to the urethra is why proper hygiene (wiping front to back) is often emphasized – it helps avoid transferring bacteria into the urethral opening. In essence, the vulva’s role in urination is straightforward: it’s the part of the anatomy that urine passes through to leave the body.
• Childbirth & Reproduction: The vulva is integral to reproduction. During sexual intercourse, sperm is deposited near the vaginal opening, from where it travels through the cervix to fertilize an egg – thus, the vulva is the entryway for sperm into the female reproductive tract. Later, if a pregnancy occurs and goes to term, the vulva becomes the exit point for childbirth. The vaginal opening stretches tremendously during vaginal delivery to allow the baby to pass through. The labia and perineum also stretch (and sometimes tear) in the process, showing how the vulva accommodates the birth of a child. Additionally, the vulva allows for menstrual flow to leave the body: during menstruation, blood and tissue from the uterus exit through the cervix, vagina, and out of the vaginal opening. In summary, the vulva is involved at the beginning of new life (by permitting fertilization) and at the entry into the world (by allowing birth), as well as managing the monthly menstrual cycle by providing an outlet for menstrual blood.

Aesthetic Diversity and Cultural Perceptions

Just as every individual’s facial features are unique, each person’s vulva is unique in appearance. There is a tremendous aesthetic diversity in vulvas and labial anatomy. This includes variations in the size, shape, and color of the labia, clitoris, and other external parts. For example, some women have labia minora that are small and do not protrude much, while others have inner lips that extend past the labia majora – either case (and everything in between) is completely normal. Labia (both minora and majora) might be more symmetrical in some people and quite asymmetrical in others (one side longer or larger). The clitoral hood might fully cover the clitoris or only partially cover it. The color of the vulvar skin can range from pink to brown to dark or reddish, sometimes even differing from a person’s overall skin tone. All these variations are healthy – medical professionals emphasize that there is no single “normal” or “ideal” way for a vulva to look. Just as eye color or nose shape varies widely, vulvas naturally come in all shapes and sizes.

Despite this natural diversity, cultural perceptions and media portrayals have often been far less diverse. In some mainstream media (such as certain magazines or adult films), vulvas are shown with a very uniform look – often with minimal inner labia visible and everything very tidy or “neat”. In fact, in past years some countries’ publishing standards airbrushed away the labia minora in images: for example, at one point Australian magazines had to edit photos so that only a single crease was visible (no protruding inner labia), otherwise the images would be classified as explicit. This kind of editing and the prevalence of a narrow range of depictions (sometimes called the “Barbie doll” or “porn-approved” look) can create unrealistic beauty standards for vulvas. Many women, upon comparing themselves to these images, might worry that something is wrong with their own anatomy if their vulva doesn’t match what they’ve seen. It’s important to know that such media images are often not representative of the average woman – in reality, vulvas are as varied as faces.

Cultural and personal attitudes toward the vulva have also evolved over time. In some cultures and historical periods, the vulva (and by extension, the labia) was shrouded in modesty or even taboo – people didn’t talk openly about it, and proper terminology was rarely used. This is one reason why even today many people aren’t familiar with the word “vulva” and instead use euphemisms or the word “vagina” incorrectly. However, in recent years there has been a growing movement to promote body positivity and vulva diversity. Educational projects and art installations have showcased the wide variety of vulvas to reassure women that no two vulvas are exactly alike. For instance, health educators have reported that when women see collections of photographs or molds of many different vulvas, they often feel relief and validation, realizing “I’m normal” after all. This kind of vulva-positive activism (sometimes called “labia pride”) encourages accepting one’s anatomy as it is and pushes back against the notion that one must look a certain way.

It’s also worth noting that cultural preferences regarding vulva appearance can differ. For example, the practice of removing pubic hair (through shaving or waxing) has become common in Western culture in recent decades, partly influenced by media and fashion (e.g. bikini trends). In contrast, other cultures have long-standing practices like labia stretching in parts of Africa, where elongating the labia minora is traditionally considered desirable – a reminder that concepts of beauty can vary widely around the world. These practices and trends show that there is no universal standard for how a vulva “should” look; much of it is culturally constructed or personal preference.

Surgical Options

While embracing the natural diversity of vulvas is ideal, some individuals do experience issues with their labial anatomy that lead them to consider labiaplasty. Labiaplasty is a surgical procedure that alters the labia (usually the labia minora, and sometimes the labia majora) for either functional or cosmetic reasons. In cases where a woman’s inner labia are especially long or enlarged, she might have physical discomfort – the excess tissue can get twisted, pinched or irritated during activities like cycling, running, or intercourse. This can lead to pain or chafing in everyday life. Others may feel self-conscious or unhappy with the appearance of their labia, especially if they believe it deviates from cultural norms. Labiaplasty can be a solution for these concerns: it typically involves reducing the size of the labia minora so they no longer protrude as much, or reshaping the labia for a smoother look. It’s important to stress that there’s a wide range of normal labial appearance, and there is no medical necessity to change one’s labia purely for aesthetics. However, for those who have chronic discomfort or significant emotional distress related to their vulva, labiaplasty is one option available. People usually undergo this surgery to relieve physical discomfort or as part of reconstructive treatment (for example, if there was an injury), and sometimes for cosmetic reasons. If someone is considering labiaplasty, they should consult with a qualified gynecologist or plastic surgeon, discuss the risks and benefits, and have realistic expectations. The decision is very personal. What’s most important is that it comes from one’s own comfort and well-being, rather than pressure from external ideals.

In summary, the vulva is a remarkable part of female anatomy – it provides protection, enables pleasure, and supports vital functions from menstruation to childbirth. Every vulva is unique in appearance, and learning about this diversity can be empowering, helping to counteract any shame or misconceptions. By understanding the vulva’s anatomy and functions, individuals can better care for their sexual health, communicate with healthcare providers, and make informed choices (whether that’s embracing one’s natural body or exploring options like labiaplasty for personal reasons). The overarching message from health experts is that knowledge and acceptance of one’s vulva – in all its individuality – is key to overall well-being.
