Unlike the penis, of which it is usually described as the female homologue, the clitoris does not enjoy an array of nicknames, euphemisms or slang terms. There is even some controversy as to its pronunication, whether this should be clitt-oris or cly-toris; dictionaries vary and some give both as correct (although the Oxford English Dictionary prefers ‘cly-toris’), but this means that there is still a decision to be made, which may cause hesitation in referring to this organ in speech. The derivation of the word is commonly alleged to derive from the Greek ‘Kleis’, meaning ‘key’, but there is some philological debate about this, as discussed in a 1937 article by Professor Marcel Cohen — reprinted by Thomas Power Lowry in The Classic Clitoris (1978).
The anatomy of the clitoris was described in 1559 by Renaldus Columbus of Padua, who claimed that previous anatomists had overlooked the very existence of ‘so pretty a thing’. His primacy was, however, contested by another eminent anatomist of Padua, Gabrielo Fallopio. Although they claimed to have discovered this organ, since antiquity there had been a powerful belief that mutual orgasm was necessary for conception, which suggests that, though unnamed, the clitoris was known to be there. Renaldus had discovered something that had not been named or mapped, but which other people (though not, perhaps, the people he would recognize as colleagues) and other traditions had already known about.
The clitoris is a tiny organ which even the woman to whom it belongs may find difficulty in seeing, except with the aid of a mirror (unless she is very flexible). It may be so concealed as only to come into view when the labia majora — the outer lips of the vagina — are separated. Located above and in front of the urethral and vaginal openings, it is structurally connected to the labia minora (the inner lips of the vagina). The visible glans of the clitoris, which is hooded by a prepuce formed by the meeting of the labia minora, is, however, only the outward and visible manifestation of much more extensive erectile tissue, which forms a padding over the pubic bone. These concealed parts are anatomically continuous with and functionally linked to the vagina. The whole structure is densely packed with nerve endings: although there are a similar number to those of the penis, they are much more concentrated and closer together. It may be noted that, although, anatomically speaking, the clitoris is homologous to the penis, the female genitalia are far more differentiated than those of the male: instead of one organ which conveys sperm and urine, and is the source of sexual pleasure, a woman has three different parts for three distinct purposes. When erotically stimulated, the clitoris becomes engorged and erectile; when a high degree of arousal is reached it retracts, with the effect that it appears to have reduced in size. Vaginal lubrication takes place along with the engorgement of the outer part of the vagina. When sexual excitement reaches its peak, orgasm takes place, with rhythmic contractions of the muscles around the clitoris and vagina. Unlike men, women have the capacity for multiple orgasm without an intervening refractory period.
The appearance of the external glans of the clitoris is very various. In some women it may be quite noticeable and an obvious analogue to the penis, in others it may be small and barely visible. Although these are innate physiological characteristics, the size of the clitoris has been assumed to relate to the sexual activity of the female, and to be excessively developed by masturbation or indulgence in lesbian practices. Successive editions of a standard British textbook of forensic medicine rather gratuitously (since female homosexuality has never been in itself a crime in Britain) included a photograph of a ‘tribade's’ clitoris well into the middle of the twentieth century.
The role of the clitoris in orgasm has been the subject of very heated controversy. Although for centuries it had been known by medical and religious authorities in Europe that titillating the clitoris had a beneficial effect on conjugal relations, rendering them more pleasant and more likely to be fertile, from the later eighteenth century this information apparently became increasingly hidden. Popular handbooks which went on being reprinted in the nineteenth century underwent expurgation and referred, if at all, much more generally to the necessity of mutual caresses and pleasure between the married couple. However, although the arousing role of the clitoris had been recognized, and even that a woman might bring about an orgasm by self-stimulation if her husband failed to give her an orgasm through intercourse, the assumption was very persistent that if women masturbated, they did so with a dildo in order to mimic penetrative intercourse. (Even today, although vibrators are most often used for clitoral stimulation, the large number of the models available vary in shape from the generally phallic to the hyper-realistically penile.) This supposition extended to the idea of women having sex with one another being thought impossible or else involving this substitution. There are some grounds, however, for believing that there may well have been an oral culture, mainly among women, which, if it could not scientifically name and describe the clitoris, nevertheless knew about its significance. This, however, was increasingly eroded by the rise of a print culture privileging published writings (the vast majority by men) above oral information, and by a variety of social changes including greater privacy and greater separation between social classes.
A new ethos of mutual sexual pleasure in marriage arose during the early twentieth century: though shared pleasure had been an ideal in the Victorian era, suppression and ignorance meant that it had not always been achieved even with the best intentions. Authors of marriage manuals emphasized the important contribution of the clitoris to the sexual arousal and satisfaction of the woman, even going so far as to suggest, in some cases, that the bridegroom should give his wife her first orgasm by manual stimulation before proceeding to defloration. Even so, clitoral stimulation was seen as something ancillary to penetrative heterosexual intercourse, which was defined as the central conjugal act.
The clitoris received, as it were, a setback as a result of the wide acceptance and popularization of Freudian psychoanalytic ideas. According to this, clitoral stimulation was immature and masculine in its nature (though it may well be doubted that little girls relate this concealed if sensitive spot to the penis, if they have ever seen a penis), and, to be truly women, women needed to abandon clitoral pleasures and effect a transfer to achieving orgasm vaginally. This theory was contested by a developing school of empirical sex research — and it should be noted that marriage advice manuals continued to stress the importance of clitoral stimulation, at least until the wife's sexual responsiveness was ‘fully developed’ Alfred Kinsey, in his study of the sex life of the American female (published in 1953), noted the vast difference in sensitivity between the vaginal wall and the clitoris and labia minora. (William) Masters and (Virginia) Johnson observed sexual interactions in a laboratory setting, and, on the basis of these observations, which involved various technological devices to measure arousal and orgasm, they concluded that orgasm was always clitoral: even if the clitoris was not being directly stimulated, indirect stimulation was taking place as a result of friction from the pulling on the labia caused by penile thrusting during intercourse. Vaginal contractions were one manifestation of the orgasm produced by the clitoris. These findings came out in 1966, contemporaneously with the enormous social changes which led to the ‘second wave’ of feminism and the short-lived ‘Sexual Revolution’. Women found that this research supplied them with a way of describing experiences which had been neglected or distorted by the masculine assumption that the acme of sexual pleasure consisted of penis-in-vagina thrusting (probably mostly quite uninfluenced by psychoanalytic ideas of the superior maturity of the vaginal over the clitoral orgasm). Works such as Danish author Mette Ejlersen's I Accuse! (British edition 1969) and Anne Koedt's 1970 article ‘The Myth of the Vaginal Orgasm’ made a forceful if anecdotal case for the preceding obliteration of women's actual experience. Shere Hite's more extensive (though methodologically much criticized) survey, published as The Hite Report in 1976, to enormous publicity, revealed the importance of clitoral stimulation to women's sexual pleasure. The notion was disseminated in a range of popular publications, handbooks on women's health from a feminist perspective, works of sexual advice, and also in numerous novels taking advantage of a new explicitness.
However, other sex researchers have contested the conclusion that there is only one kind of orgasm, suggesting that, at least from subjective experience, some women do have orgasms, which they describe as ‘vaginal’ or ‘uterine’ from penetrative intercourse, and that these are qualitatively distinct from those achieved through specific clitoral stimulation. The connotation of immaturity has been lifted from the clitoral orgasm, and there is some evidence that women who prefer vaginal orgasms tend to be more passive, dependent, and anxious. It can be argued that the focus of attention on the clitoris has perhaps obscured the contribution to sexual pleasure and orgasm of the sensitive erectile tissues of the rest of the vulva.
Although the clitoris is such a small and apparently insignificant organ, there are and have been widespread conceptions that it is dangerous and threatening. There are substantial areas of the world today, in Africa and the Middle East, in which clitoridectomy is still routinely practised on ritual and hygienic grounds — though the number of cultures which practice it are far fewer than those in which some kind of circumcision of the penis is performed on boy children or youths in transition to manhood. The practice is deeply embedded in national and religious cultures, and has proved very difficult to extirpate; attempts to do so have caused crises for colonial powers in Africa. While many of the cultures which practice it are Islamic, clitoridectomy is not coterminous with the Muslim world: it is found among other religious groups in the regions in which it is common, and is not practised in all Islamic nations.
Clitoridectomy takes different forms, from a relatively minor removal of a small amount of flesh from the tip of the clitoris to almost complete extirpation, along with other practices such as infibulation and sewing up of the labia. The effect of this mutilating operation on the subsequent sexual life of the women involved is usually assumed to be deleterious in the extreme, although there is a little, perhaps rather anecdotal, ethnographic evidence that some women who have undergone clitoridectomy are nevertheless capable of experiencing orgasm. This may depend upon how much of the underlying concealed erectile tissue remains. The trauma of the operation, performed normally on young girls around the age of 8, without anaesthetic, by traditional practitioners, must be considerable. Subsequent infection and scarring can have long-term implications for future fertility and safety in childbirth. Such operations are regarded as reprehensible and unethical by Western medicine, although there have been cases of private practitioners performing the operation under surgical conditions in the UK for members of cultures in whom it is regarded as an essential attribute of the marriageable female.
However, there is no reason for an attitude of complacent superiority. During the 1860s the British surgeon Isaac Baker Brown performed an unknown number of clitoridectomies at his London Surgical Home. He believed that female masturbation was widely prevalent and the cause of a number of nervous ailments, including epilepsy, a point of view he advanced in his book On the Curability of Certain Forms of Insanity, Epilepsy, Catalepsy and Hysteria in Females (1866). The operation was, however, widely regarded as mutilating and shocking (especially given Baker Brown's rather cavalier attitude towards consent), and in 1867 he was expelled from the London Obstetrical Society and the London Surgical Home was closed. Baker Brown subsequently became insane. Clitoridectomy in Britain never recovered from this and did not become part of the medical repertoire, although it went on being practised in the US, to an extent which it is probably impossible to ascertain, well into the twentieth century. While the excesses of the advocates of ‘Orificial Surgery’, who advocated excising the clitoris as the remedy for a range of ailments, were probably not typical, as late as 1936 Holt's Diseases of Infancy and Childhood was not averse to recommending circumcision or cauterization of the clitoris as a cure for masturbation in girls. These might be extreme options, but there were certainly devices available to prevent girls (and possibly women) gaining access to their clitoris for self-stimulation.
Surgery of the clitoris still takes place. There are, of course, various legitimate medical reasons for operating on this organ, such as various forms of malignancy, but they are fairly rare. These days the clitoris is not, in Western medicine, excised to take away the unruly sexual desires of women, but adjusted to make it more conformable to the demands of penetrative intercourse. It has been observed that, in most coital positions, when the penis is in the vagina, there is rarely direct stimulation of the clitoris as well, without the intervention of hands (or devices such as ‘French ticklers’). Operations have been reported endeavouring to relocate the clitoris somewhere where it will be more likely to receive stimulation from simple penile thrusting, nearer the vaginal entrance. The equivalent to circumcision of the penis has also been performed, trimming back the clitoral hood to expose the glans to increase ‘sensitivity’. Alleged ‘adhesions’ have also been removed. The value of these operations is exceedingly dubious. They reflect a mechanistic approach to sexual functioning similar to the use of vaginal dilators for spastic contraction of the vagina: altering or trying to alter the female genitals to make them conform to the cultural norm rather than recognizing that the cultural norm has ignored the requirements of the female genitalia.
Perceptions of, and attitudes towards, the clitoris, provide a powerful reflection of wider societal attitudes to female sexuality, whether this is seen as so dangerous that it must be eradicated, or simply needing to be brought into a greater complementarity with male sexual needs.

The clitoris is a sexual organ that is present only in female mammals. In humans, the visible button-like portion is located near the anterior junction of the labia minora, above the opening of the urethra and vagina. Unlike the penis, which is homologous to the clitoris, the clitoris does not contain the distal portion of the urethra. The only known exception to this is in the Spotted Hyena. In this species, the urogenital system is unique in that the female urinates, mates and gives birth via an enlarged, erectile clitoris, known as a pseudo-penis.[1]
In humans, the clitoris is the most sensitive erogenous zone of a woman, the stimulation of which may produce sexual excitement and clitoral erection; its continuing stimulation may produce sexual pleasure in the woman and orgasm.

The word is pronounced /ˈklɪtɒrɪs/ (
listen) or /klɪˈtɔərɪs/ (
listen). The plural forms are clitorises in English and clitorides in Latin. In slang, it is sometimes abbreviated as clit, which originated in the 1950s. The OED suggests that the pronunciation /ˈklaɪtɒrɪs/) is also used in the UK, and gives the likely etymology as coming from the Greek κλειτορἰς, kleitoris, perhaps derived from the verb κλεἰ-ειν, klei-ein, to shut. The Online Etymology Dictionary maintains that the etymology of this diminutive is still uncertain noting that many sources take Κλειτορίδ, kleitorid, literally from the Greek "little hill”. Other etymological candidates are key or latch, to touch or titillate lasciviously, to tickle, to be inclined (toward pleasure) and slope, from the same root as climax. It has been noted in German as der Kitzler meaning "the tickler". Its Latin genitive is clitoridis, as in "glans clitoridis".
The head or glans of the clitoris is roughly the size and shape of a pea, although it can be significantly larger or smaller. The clitoral glans is highly sensitive, containing 8,000 nerve endings, double the nerve endings as the analogous organ in males, the glans penis.

The clitoris is a complex structure, with both external and internal components. Projecting at the front of the labial commissure where the edges of the outer lips (labia majora) meet at the base of the pubic mound is the clitoral hood (prepuce), which in full or part covers the head (clitoral glans). Following from the head back and up along the shaft, it is found that this extends up to several centimeters before reversing direction, branched resulting in a shape like an inverted "V", and extending as a pair of "legs" known as the clitoral crura formed of the corpora cavernosa, which are concealed behind the labia minora, and terminating attached to the pubic arch, according to some,[2] or following interior to the labia minora to meet at the fourchette, according to others.[3]
Associated are the urethral sponge, clitoral/vestibular bulbs, perineal sponge, a network of nerves and blood vessels, suspensory ligaments, muscles and pelvic diaphragm.[4]
There is considerable variation in how much of the clitoris protrudes from the hood and how much is covered by it, ranging from complete, covered invisibility to full, protruding visibility. An article published in the Journal of Obstetrics and Gynecology in July 1992 states that the average width of the clitoral glans lies within the range of 2.5 to 4.5 millimetres (0.098 to 0.18 in), indicating that the average size is smaller than a pencil-top eraser. There is no identified correlation between the size of a clitoris and a woman's age, height, weight, use of hormonal contraceptives, or being post-menopausal. Those who have given birth tend to have slightly larger measurements.[citation needed]
Masters and Johnson were the first to determine that the clitoral structures surround and extend along and within the labia, determining that all orgasms are of clitoral origin.[5] More recently, Australian urologist Dr Helen O'Connell, using MRI technology, noted a direct relationship between the legs or roots of the clitoris and the erectile tissue of the clitoral bulbs and corpora, and the distal urethra and vagina.[6] She asserts that this interconnected relationship is the physiological explanation for the conjectured G-spot and experience of vaginal orgasm taking into account the stimulation of the internal parts of the clitoris during vaginal penetration.[7] Some individuals who experience orgasm from both direct clitoral stimulation of the glans and vaginal access to the internal bodies may distinguish between them in terms of both the physical and general sensations associated with each.
During sexual arousal and during orgasm, the clitoris and the whole of the genitalia engorge and change color as these erectile tissues fill with blood, and the individual experiences vaginal contractions. Masters and Johnson documented the sexual response cycle, which has four phases and is still the clinically accepted definition of the human orgasm. More recent research has determined that some can experience a sustained intense orgasm through stimulation of the clitoris and remain in the orgasmic phase for much longer than the original studies indicated, evidenced by genital engorgement, color changes, and vaginal contractions.[8]
During the development of an embryo, at the time of development of the urinary and reproductive organs, the previously undifferentiated genital tubercle develops into either a clitoris or penis, along with all other major organ systems, making them homologous.[4] The clitoris is formed from the same tissues that would have become the glans and upper shaft of a penis if the embryo had been exposed to “male” hormones. Changes in appearance of male and female embryos begin roughly eight weeks after conception. By birth, the genital structures have developed into the female reproductive system.[9]
Embryo sex based on external genitalia is apparent to a doctor at the end of the 14th menstrual week, and the sex can usually be identified by an ultrasound after 16 to 18 menstrual weeks.[10] A condition that can develop from naturally occurring or deliberate exposure to higher than average levels of testosterone is clitoromegaly.
The clitoris has been rediscovered repeatedly over the centuries (Harvey 2001, Laqueur 1989). Over a period of more than 2,500 years, some have considered the clitoris and the penis equivalent in all respects except their arrangement.[3] Medical literature first recognized the existence of the clitoris in the 16th century[citation needed]. This is the subject of some dispute: Realdo Colombo (also known as Matteo Renaldo Colombo) was a lecturer in surgery at the University of Padua, Italy, and in 1559 he published a book called De re anatomica in which he described the "seat of woman's delight". Colombo concluded, "Since no one has discerned these projections and their workings, if it is permissible to give names to things discovered by me, it should be called the love or sweetness of Venus."
Colombo's claim was disputed by his successor at Padua, Gabriele Falloppio (who discovered the fallopian tube), who claimed that he was the first to discover the clitoris. Caspar Bartholin, a 17th-century Danish anatomist, dismissed both claims, arguing that the clitoris had been widely known to medical science since the second century. Indeed, Hippocrates used the term columella (little pillar). Avicenna named the clitoris the albatra or virga (rod). Albucasis, an Arabic medical authority, named it tentigo (tension). It was also known to the Romans, who named it (vulgar slang) landica.[11]
This cycle of suppression and discovery continued, notably in the work of De Graaf (Tractatus de Virorum Organis Generationi Inservientibus, De Mulierum Organis Generationi Inservientibus Tractatus Novus) in the 17th century and Kobelt (Die männlichen und weiblichen Wollustorgane des Menschen und einiger Säugetiere) in the 19th. De Graaf criticised Columbo's claims for this. (Harvey, Laqueur).
The full extent of the clitoris was alluded to by Masters and Johnson in 1966, but in such a muddled fashion that the significance of their description became obscured. That same year, feminist psychiatrist Mary Jane Sherfey published an article on female sexuality that described in detail the extensive nature of the internal anatomy of the clitoris[citation needed] and in 1981, the Federation of Feminist Women's Health Clinics (FFWHC) continued this process with anatomically precise illustrations.[3] Today, MRI complements these efforts, as it is both a live and multiplanar method of examination.[6]
The external part of the clitoris may be partially or totally removed during female genital cutting, also known as a clitoridectomy, female circumcision, or female genital mutilation (FGM); this may be a voluntary or involuntary procedure. The topic is highly controversial with many countries condemning the traditions that give rise to involuntary procedures, and with some countries outlawing even voluntary procedures. Amnesty International estimates that over 2 million involuntary female circumcisions are being performed every year, mainly in African countries.
In various cultures, the clitoris is sometimes pierced directly. In U.S. body modification culture, it is actually extremely rare for the clitoral shaft itself to be pierced, as of the already few people who desire the piercing, only a small percentage are anatomically suited for it; furthermore, most piercing artists are reluctant to attempt such a delicate procedure. Some styles, such as the Isabella, do pass through the clitoris but are placed deep at the base, where they provide unique stimulation; they still require the proper genital build, but are more common than shaft piercings. Additionally, what is (erroneously) referred to as a "clit piercing" is almost always the much more common (and much less complicated) clitoral hood piercing.
Enlargement may be intentional or unintentional. Those taking hormones and/or other medications as part of female-to-male transition usually experience dramatic clitoral growth; individual desires (and the difficulties of surgical phalloplasty) often result in the retention of the original genitalia, the enlarged clitoris analogous to a penis as part of the transition. However, the clitoris never completely adapts to the masculinization of its owner and will never be able to ejaculate or urinate and is small in comparison to the genitalia of a natural-born male. On the other hand, use of anabolic steroids by bodybuilders and other athletes can result in significant enlargement of the clitoris in concert with other masculinizing effects on their bodies. Temporary engorgement results from suction pumping, practiced to enhance sexual pleasure or for aesthetic purposes.
