The point Gräfenberg, often also known as point G, is a small area of the genital area of the women located behind the pubis and about urethra 1 Some women inform that it is a question of an erogenous area which, once stimulated — it is already the spongy urethra or her part — can take to the strong sexual excitement, powerful orgasms and the ejaculation femenina.2 The point Gräfenberg, as it is described traditionally, it is located between 2.5 to 7.6 cm from the vaginal gap and the urethra up to the (previous) frontal part of the wall vaginal3 and is a sensitive area that can be a part of the prostate femenina.4

Although the point G has been studied from the decade of the 40,5 the adult magazine pdf disagreement persists as for the definition and location on its existence as a different structure. A British study realized in 2009 concluded that its existence is not verified and is subjective, being based on questionnaires and personal experiences. Other studies, using ultrasound, found physiological evidence of the point G in the women who declare to have had orgasms during the coitus. There exists also the hypothesis of which the point G is in itself an extension of the clitoris and which this is the cause of the vaginal orgasms.

It worries some sexologos and other investigators that the women could think disfunctional themselves if they do not experience the point G, and emphasize that it is normal not to experience it.

The term «point G» was minted by Addiego and collaborators in 1981, in honor to the German Ernst Gräfenberg, he discovered it in the 40s by chance, while he was studying the feminine urethra, although its investigations in the 40s were dedicated to the stimulation uretral and not to the stimulation of the internal vaginal wall. The concept reached the popular culture after the publication of The G commercial and Other Recent Discoveries About Human Sexuality for Alice and collaborators in 1982, but it was immediately criticized by the gynecologists most emphasized in those años.1 They denied its existence because it is not easy to find unless it is stimulated; autopsy studies, on the other hand, have failed in finding it. It was even later that the existence of the point was demonstrated G by different remarks, which changed of opinion.

Controversy

A controversy exists about the proper existence of the point G. In a study carried out by King's College of London, a questionnaire on sexual customs was sent by mail to twin women and identical twins; and half of the women answered that he was thinking that it was possessing this point G, while another half believed that not. The results of the survey have been a criticism object for its absence of scientific rigor after questionnaire 19 talk each other of a study based on one

The magazine Sexual Journal of Medicine there published the results of a study realized by Emmanuele Jannini, teacher of sexology doctor of the University of l'Aquila in Italy who was affirming that it is possible to determine the size and the form of the layer that is behind the main vaginal wall, the area uretrovaginal where the point would be located G, by means of an ultrasound exploration or ultrasound scan.

Study published in Sexual The Journal of Medicine documents that this anatomical structure yes exists. Adam carried out stratum for stratum of a previous dissection of the vaginal wall in a corpse of 83 years of age. The dissection establishes the presence of the point G, a quite delineated structure of salía placed in the back area (back) of the membrane perineal, 16,5 mm of the top part of the meato uretral, forming an angle of 35 grades with the side street (side) the border of the urethra.


The clitoris is the erectile sexual organ that is in the top part of the vulva of the woman, being its function that of providing sexual pleasure. The clitoris is a trace of the formation of a penis during the embryonic development.

It is joined to the lips least and covered partially by these. In fact, there are usually only visible the hood and the glans of the clitoris, which are in the top part of the least lips, and which are scarcely a tenth part of the entire volume of the clitoris adult magazines pdf.

When the cells of the internal face of the prepuce of the clitoris flake off and do the greasy degeneration that characterizes them, they form the esmegma, as in the masculine case. The habitual hygiene prevents this one from accumulating. If it was doing it, it would produce annoyance and adhesions, as it happens, in fact, in the cases of fimosis of the clitoris.

On him there concentrate the nerves that produce sexual pleasure in the woman. Until now this is its only well known function.

In some societies of the African continent the sexual mutilation of the women is practised: the clitoris ablation consists of its mutilation before the young people comes to the menarche to try to prevent from knowing the sexual pleasure.

Size

The clitoris in all its length can go so far as to have a size from 10 to 13 mm, while the glans clitoriano measures between 3 and 4 mm wide and 4 and 5 mm long (in the rest state) while in erection it can reach 1 to 1,5 cm long in the woman I mediate. The visible part of the clitoris is the glans and it is extremely sensitive to the direct stimulation in most of women, preferring the indirect stimulation across the prepuce or hood clitoriano, the glans constitutes only the eighth part of the whole clitoris.

Development

In the embryonic development, there is a phase in which both sexes are indistinguishable. The development of the clitoris and the external sexual organs of the woman begin from the 7th week of the embryonic life. The clitoris will develop from the similar genital tuber to the glans of the man.

In very early phases, the clitoris looks like a small penis. Later, due to the action of the maternal hormones, he acquires its location — previous to the urethra — and a size smaller than in the male.

Stimulation

The stimulation of the clitoris can be done in a direct or indirect way. Most of the women masturbate stimulating the area of the clitoris, taking care that he stays lubricated.


The vagina is a conduit fibromuscular elastic tape, it departs from the internal genital organs of the woman – then it departs from the feminine reproductive device. In the females of the mammals, it spreads from the vaginal foyer up to the uterine cervix. In some scientific words the prefix is used colpo - to indicate vagina, as in colporragia, flow of vagina.

The vulva and the vagina, two different anatomical structures that must not make a mistake, are the organs of the copulation in the mammals. Fulfilling this reproductive function, it is the feminine organ that receives the penis during the coitus, the low part of the channel of the childbearing, and the route of exit of the menstruation.

In the emptiness state, it is smoothed of forward to behind and its walls apply one to other one in all its extension less in its extremities.

Measured type

The length of the vagina in human beings changes according to races and genotipos is from 8 to 11 cm like average. It has in its previous face a 7 cm length, while the later one, which is the longest, measures 9 cm. Nevertheless it can dilate, increasing its length three or four centimeters more normal thing.
In suidos (pigs and jabalíes) of average size, it measures from 10 to 12 cm long. The caliber is small adult magazines pdf and with a thick muscular layer formed by two layers of longitudinal fibres and in way one of circular letters.
In the carnivora it is relatively big (approximately 12 cm in an animal of average size), it becomes closer cranealmente and the fornix does not differ. The muscular layer is thick and formed, fundamentally, by circular fibres. The mucous membrane forms longitudinal creases.
In the equidos it measures from 15 to 20 cm long. Its caliber is enormous, since it can reach approximately 10-12 cm in diameter when it is distended (even being limited its dilatabilidad by the pelvic wall). There are no external lines that allow to see the limits of the vagina to simple sight, in contrast to other species.
In bovidos it is much bigger than in the mare. More wide and more capable (as for its aptitude to be distended or to monopolize). Also longer (approximately 25 to 30 cm in weightlessness, enough more during the pregnancy), and its thickest walls. It has a few almost exclusive organs of this family, the channels of Gartner, of function secretora.
Layers of the vaginal wall type


Wall vaginal (mucous membrane), photo of microscope of light.

The mucous tunic forms enough creases (vaginal wrinkles, depending the orientation of the same ones according to the species) and sometimes it goes so far as to close completely the vaginal light. Two layers:

Epithelium: Its diameter ranges greatly, average 3 cm. In the epithelium, not mucous, stratified plane, large number of glucogeno exists during the phase proliferativa or folicular, produced by cells eosinofilas, whose fermentation produced by the bacterial flora, which transforms it into lactic acid, he awards the acidic character to the surface of the vaginal epithelium. During the phase secretora or luteinizante, the thickness of this layer diminishes greatly, and its cytology also changes, dominating the situation the cells basofilas, together with leukocytes and diverse bacteria. It is in this phase (and not in the previous one) when the masculine ejaculation (across the penis) can produce with much major probabilities the pregnancy (conception), since in the previous phase the vaginal light is closed. It is, in fact, in the phase secretora when there are generated more infections (due to the lactic acid absence). It is possible that this "inoffensive" stage helps to the survival of the sperms. Also, the leukocytes of the proper plate can help to avoid some infection (it is possible that some microorganism crosses the vaginal epithelium).
Proper plate: It is the conjunctive lax textile that joins the epithelium to the muscular layers. In its deep area there exist thicker fibres and glasses of major caliber, giving him this way erectile textile, forming these glasses the called vascular caverns.
Muscular tunic

The smooth muscle possesses, in turn, two differentiated strata: I intern one, composed of circular fibres, and one day pupil, more thickness consisted of muscular longitudinal fibres also smooth.
As for the skeletal muscle, in the low part there exists a species of sphincter, which closes the vagina. It is a question of skeletal muscular cells of the muscle.
Accidental tunic

It is a question of lax connective textile, which contains a big venous plexus.

Relation between vagina and vulva

1. Major lips.
2. Clitoris.
3. Less lips.
4. Urethra.
5. Glands of Skene.
6. Vagina.
7. Bartolino's glands.
The vulva and the vagina are a fundamental part in the sexual intercourse and in the childbearing, and for its proximity – in colloquial language – one tends to confuse the first one, with the name of the second one, what is a conceptual error.

The vulva is the external part – external genital organs – of the feminine reproductive device, and it includes several structures – as there are the genital lips, the clitoris, the glands of Skene and Bartolino, and the exit on the outside of the urethra and vagina–.

The vagina is one of the parts of the internal genital organs of the feminine reproductive device sex magazine pdf, that in turn, it includes other organs, like the womb, horns of Falopio or ovaries.

The vagina then, it is the fibro-muscular conduit that joins the womb with the vulva – the exterior – and its visualization, to simple sight, it is impossible. In the images of the right the biggest and less lips have separated manually, to be able to take a vision of the initial part of the conduit as its interior face.

Irrigation

The vascularizacion of 1/3 top of the vagina is given by vesico-vaginal branches originated from the uterine artery, which emerge before the uterine artery crosses ahead of the ureter of the same side, and of the cervico-vaginal branches originated from the same uterine artery after crossing the ureter.

The average third of the vagina is irrigated by the vaginal artery, branch of the hypogastric artery. The artery hemorroidal average, which is also a branch of the hypogastric one, helps to irrigate 1/3 low of the vagina, as well as branches of the artery pudenda internal.

Functions of the vagina

It serves for the canalization of the menstrual flow during the menstruation.
It is the orifice for which the man introduces the penis in the erection state during the coitus.
It is the route where the semen interferes with the sperms for the fertilization of one or more ova of the woman.
It facilitates the sexual act, for the lubrication of the secretions of the glands of Bartholin.
It is the exit of the fetus and of the afterbirth of the womb at the end of the gestation period.
Sexuality and myths

The penis gets in the vagina during the coitus. The vagina is, together with the clitoris and the point G, one of the areas that they are provided with the biggest number of nervous completions. The cunnilingus (the sexual contact of the feminine genitals across the mouth and the language of another person, is this one man or woman) is one of the multiple possibilities of obtaining pleasure for a woman. There are notable individual differences on this matter: there are women who obtain pleasure sexual only or principally across the cunnilingus, there are women who obtain pleasure sexual only or principally with the penetration of the penis.

In someone babies (in fact, less than it was supposed), the vagina is protected by the hymen or «virginity«, a thin membrane with some perforations that allow to go out the menstruation. Normally this membrane gets worn or gets lost for factors of the common life (the sports activity, the manipulation, etc.) . In last times, it was a common belief that the women had to preserve the intact hymen until they had the first sexual intercourse, when it was supposed that it was breaking with the penetration of the penis and was causing a bled brief one. Nevertheless, nowadays sex magazines pdf it is known that there are multiple myths on this matter: they are in fact very little women who are born with a membrane (be already finished or incomplete) and, of that they are born with her, they are also in fact very few those that, in its first sexual intercourse, there present the bled one and/or pain (myths that there has studied thoroughly the team of the Mexican sexologo oscar Chavez Lanz). In some cultures that still give him big value to the feminine virginity, this fact is the factor most used to determine the loss of the virginity and to judge and to censure the sexuality of the woman.

In the popular culture

The western society has treated in general the sexuality, the feminine vagina especially, how he is afraid of taboo and with many prejudices partly for the religious pressure.

These circumstances and the changes in the modern values, in the human rights or in the freedom of expression might explain the big success of the stage play of Eve Ensler, translated in the Spanish language world like The monologues of the vagina or The vaginal monologues. In its premiere in New York in 1996 and in its different versions about the world, it achieved that the word vagina was appearing in numerous and important mass media.

Also successful and prize-winning series of television Sex and the City, translated in countries of Spanish speech as Sex in the city or Sex in New York (also with cinematographic versions), contains many discussions about the feminine sexuality, and of course the vagina. In countries as China or Kenya it was censured by its sexual suppressed high place.

Owed especially to the proper taboo, popularly the vagina and the vulva often have made a mistake in the popular vocabulary, in addition to sharing or having different meanings, usually with offensive or pejorative sense. Many euphemisms have been invented in the ambience of the popular language (and this has happened in all the languages of the world, in all the cultures) to name both to the vagina and to the vulva, disguising it and comparing it with multitude of objects of form and similar characteristics.
