Have sexual intercourse the vagina in the process
Say from the essence, vagina to actively the effective stimulate of the response, reaction be not and at will for the insertion of penis to work well to prepare a process.Be like the erection of penis be a man to hand over a the species direct physiology that the joyful reason need to respond, extend of vagina with lubricated to also obviously and mentally hand over joys invitation to provide direct physiology digit to advertise for for the female.When vagina conduct and actions a sexual organ to evaluate, have to the point consider that the vagina responds the variety in the period in sex.
Female’s accepting the sex stimulus empress tugor of any form to start increase Gao Shi2’s first proof that physiology respond is a vagina wall to appear moist, this “perspiration” the phenomenon usually takes place in 10-30.Have another in the last years people as to it’s the source made a great deal of research, the effect confirmed regardless all of the temple jugular mucilage or greater vestibular gland liquids aren’t it cardinal source.Regardless being uterus and double side ovary oviduct, uterine tube, Fallopian tube to cut off is remarkable behind of”castration” patient, still implement the patients of artificial colpoplasty all exist this kind of sexual impulse cause of secretion activity, this completely expeled its secretion is come from inside temple neck or greater vestibular gland of possibility.The discharge, secretion can have certain influence to the vagina acidity, it has with quantity and length of secretion time of discharge, secretion certain relation, the pH value goes up after carry on long-playing sexual activity.
In the sex stimulation period the process, in the whole vagina the palatine canal of the structure, the dispersal appears from the fold surface of a drop with small transudate appears like the forehead of the night sweat pearl be similar.When sex tugor increases Gao after, isolated of the small drop blends to become 1 F gradually on the vagina wall even flashlight of overjet thing, make the vagina wall attain completely well moist.So, be placed in the women of sex response, reaction condition a short moment to attain to well ready to after get into stimulation period of stage.Vagina wall this kind of quickly appearing the exudation mechanism of abundant exudation kind material be in order to wrapping to round show of the whole venous plexus of vagina palatine canal Zhao to extend to result in.Surroundings all vascular plexuses obviously and all participated this explosion afferent hyperemia, congestion of vagina wall to respond.Study a confirmation over a long period of time, on the vagina wall any basic and nonexistent grain form material, to the bio-chemical composition of these transudates and them to the chemical effect of the normal vagina is in the research now.The before the event is very intimate the process extension be more long, don’t ejaculation front of hand over happy time to keep on more long, the discharge, secretion of vagina also produces more many.After attain exciting period, sex kept with long hours stimulus the activity be always a fixed factor which affects vagina lubrication condition, and and how the stimulus type(flesh of or mind of) of its adoption is irrelevant, and also have nothing to do with whether women’s end can attain the high tide of sex response, reaction to release or not.
Nervous keep on to evolve in sex of stimulation mid-term, can see of the vagina works well the anatomy of the preparation and the proof of the physiology for the coitus, copulation:The vagina section inside the palatine canal 2/3 extension with extend.Can observe irregularly extend of the vagina wall when the stimulation expect and will end a demulcent therapy, reconciliation terrace a period and will soon come kinematic, the vagina palatine canal appears to not and at will show Zhao to extend, then appears the chalasis of indiscipline, the vagina that is at this time wall of the tension seemed to disappear, hence was placed in the women of sex response, reaction condition to appear clinical up the vagina that can confirm palatine canal inside section 2/3 of obviously extend, in fact border the meaning be obvious.When sex tugor increase, temple neck and temple body slow-movingly jack up, get into a false pelvis upward and backward, this for the jugular cross section part of the temple in vagina result in one species tent action.Don’t multipara the true conjugate diameter, anteroposterior diameter of this part can from 2 Li rices at ordinary times or so increase to 6 Li rices or so, be also say that increase breadth 300% or so.Arrive to°from the frenulum of pudendal labia a fornix mural behind of the vagina length has never be irritated as well of 7-9 Li rices increase to 9.5-10.5 Li rices and equally lengthen 2.5 Li rices.In addition to lengthen, extending, the stimulation expect of another a performance are a show of color the Zhao deepen, because of the vagina wall vascular and obvious hyperemia, congestion, vagina wall from is change into by the pink of the Zi body hormone stimulus at ordinary times dark purple color.At stimulation earlier period, the discoloration is to spread at, disharmony of, expect along with the terrace of arrival and pelvis blood vessel bloodshot turn worse, the whole vagina take care of of the color deliver dark and more even demulcent therapy, reconciliation obvious.
Arrive after the terrace period the vagina not and at random extends to result in of the inevitable outcome be at first of the fold stretches to flatten gradually, the vagina epithelium become thin and expand.Expect to extend a section inside the vagina on the basal in the stimulation 2/3 of further mutation breadth and mutation longus is very limited, while expecting with stimulation compare can neglect not to account.The vagina expected to attain in sex stimulation the biggest secretion rate also has a descent, especially at the sex nervous level last longer is more such.
The terrace expects the biggest characteristics of vagina response, reaction BE, expect a section outside the vagina that the only light and tiny degree extend in the stimulation 1/3, along with sex strain level of increase Gao, this special district included a bulb of vestibule to take place to show partial afferent hyperemia, congestion and swelling of Zhao, this will make section outside the vagina 1/3 center antrums contract at least 1/3.This not and at will swelling a process is the explicit marking which attains a terrace period and certainly most women also can’t realize or detect to this kind of variety.Wrap to round a section outside the vagina 1/3 afferent hyperemia, congestion regions plus a lesser lip of pudendum of the hyperemia, congestion swelling established the orgasm physiology of the vagina the anatomy basal of the expression, is called a terrace to expect special”vagina terrace”.Its action has already been another place once making detailed introduction and forgive not to give unnecessary details.
The high tide expects the physiology of the sexuality high tide of the vagina palatine canal explosion to respond, substantially is only limit at a section outside the vagina 1/3 of high tide terrace of.Of the vagina hair the contraction is a continuous of, at least 3-5 times, at most 10-15 times, the partition is 0.8, the partition prolongs gradually after 3-6 first contractions, and the contraction strength also dies down gradually.At the tallest tugor level(”high tide condition”) the high tide expect and can keep on 2-4, then convulse disappearance at a clonus contraction by start and recover the regulation of 0.8 above-mentioned partitions a contraction.
Being the marking that the regression expects to start may be a section outside the vagina 1/3 of retreat sex change, hyperemia, congestion decrease, section outside the vagina 1/3 of central ntrum true conjugate diameter, anteroposterior diameter increment, slowly vagina palatine canal inside section 2/3 also recover to fall to sink of do not stimulate a condition.The temple neck reset and the color regression completes within 10-15 minutes.
Conveniently lift once female attach a greater vestibular gland of the gonad in the performance in the sexual activity, understanding these physiology response, reactions can clarify many facts.When the sexuality excite, control the parasympathetic nerve stimulation of greater vestibular gland, cause to be located on a vaginal orifice the greater vestibular gland of two sides to secrete a little amount and thin and yellow and alkaline mucilage.The secretion liquid having another in the last years to once affirm it successfully provided an enough lubrication action with have no painfully toward insertion inside the vagina for the penis.In fact this secretion activity is only take place in exciting later period or terrace earlier period, don’t multipara usually each the side only can produce a drop of mucilage and the multipara occasionally can produce 2-3 drops.Having never observed it can produce enough lubrication material to contribute to a penis toward the insertion of vagina.The alkaline property which even once mistakens for a greater vestibular gland secretion a liquid contributes to the acidity which remisses a vagina and promote a spermatozoon thus in take time in the vagina.In fact, because its secretion amount is regardless very tiny, come up to see from the physical volume or the chemistry and all attain a neutralization purpose impossibly.Have sexual intercourse record of the vagina pH value go up the secretion that the phenomenon is still vagina wall to result in.So say according to time and amount of its secretion, the secretion of greater vestibular gland since can’t lubricate a vagina more can’t provide for the penis insertion enough moist.
